Description

200923045 九、發明說明： 【發明所屬之技術領域】 本發明係關於壓感膠帶’更準確而言係關於即使在基材 係聚烯烴基材時亦具有極佳膠黏性及極佳抗邊緣剝離性且 能夠展示適宜再度捲繞力之壓感膠帶。 【先前技術】 迄今為止’作為用於束紮金屬線（例如各種電線及電纜） 之壓感膠帶（束紮壓感膠帶），自其易操作性及阻燃性角度 而° 廣泛使用者係具有聚氯乙烯樹脂基材（下文中此可 稱為PVC’’）之壓感膠帶。然而，由於使用pvc之壓感膠帶 在焚化時產生有毒氣體，故最近已使用具有不含有諸如氣 等鹵素原子之塑膠基材之壓感膠帶（此可稱為"無鹵素膠帶"）， 尤其係具有聚烯烴樹脂組合物基材之壓感膠帶，該聚烯烴 树脂組合物含有聚烯烴樹脂作為其主要成份。 而’使聚烯煙樹脂組合物如同PVC —樣具有適用於束 紮之均衡之強度、撓性及應力鬆弛特性卻極為困難。因 此為使此聚稀煙樹脂組合物能適宜用作束紮應用之壓感 膠帶之基材，已進行多方面研究，例如關於樹脂組合物之 強度與撓性之平衡（參見JP_A_2001_192629或Jp_A_2〇〇l_ 311061) 〇 另方面’已提出具有良好黏性及穋黏性之無鹵素膠帶 (參見 JP-A-2001-131509或 JP-A-2001-164215)。 亦已提出水性分散液型膠黏組合物，其含有丙烯酸系聚 合物與所用作為其單體組份之矽烷單體（參見JP_A_2001- 127127.doc 200923045 131511或JP-A-2003-176469)。 然而’至今仍未完全解決應力鬆、弛問題，且由於在用具 有聚稀煙樹脂組合物基材之壓感膠帶束紮後，壓感膠帶I 邊緣可能剝離，因此其㈣具有可靠性問題且由於壓感膠 帶之再度捲繞力太大且膠黏劑被其自身背面絆住，或相 反，當壓感膠帶之再度捲繞力較小時，不能用該膠帶緊固 束紮金屬線及諸如此類’因此其仍具有其他易操作性問 題。 如上所述具有良好黏性及膠純之無“壓感膠帶就其 在用於束紮後防止料自其邊剝離之抗邊緣剝離性及其易 操作性（再度捲繞力）而言仍不盡如人意。 關於壓感膠帶可對其易操作性有一些影響之再度捲繞特 性’在此之冑已提出再度捲繞特性問冑可藉由添加增塑劑 至膠黏劑中予以解決。 關於抗邊緣剝離性，藉由添加增塑劑至基礎聚合物中或 使增塑劑自基材轉移至基礎聚合物或藉由添加增黏劑至基 礎聚合物中使壓感膠帶之黏性及膠黏性增加的方法已為吾 人所習知。然而，並沒有揭示或提出此增塑劑與增黏劑之 具體組合之效果。 鑒於這種情況，為解決抗邊緣剥離性問題及壓感膠帶再 度捲繞中之易操作性問題，本發明者提供用於壓感膠帶之 膠黏組合物，該壓感膠帶具有由聚烯烴樹脂組合物構成之 聚烯烴基材，其中添加松香酯增黏劑至膠黏劑中藉此改良 膠帶之抗邊緣剝離性，且藉由提供給膠帶之增塑劑及石油 127127.doc 200923045 樹脂的效果適當控制帶之再度捲繞力。 然而’吾人期望具有更加改良之膠黏性及抗邊緣剝離性 以及具有適且再度捲繞力之壓感膠帶。 具體而言’在含有交聯劑之膠黏組合物系統中，當交聯 劑在系統中分散性較差(不均勻或一點也不均勻)時，或當 形成壓感膠層之乾燥條件波動（不穩定或一點也不穩定胃) 時，則由於在再度捲繞壓感膠帶中所需之再度捲繞力可能 增大或所再度捲繞之膠帶可能發出大的_音而亦存在一些 問題。 一 此外^在用作基材之塑膠膜中含有用作阻燃劑之多價 金屬鹽（例如金屬氫氧化物）時，可能出現壓感膠帶之膠黏 強度可能隨時間而大大降低之現象。另外，吾人已知，由 於該現象之緣故，膠帶之邊緣可容易地剝離，從而造成膠 帶之實用性問題。如此，當在基材中含有多價金屬鹽時， 則該多價金屬鹽可與膠黏劑之基礎聚合物中之反應性官能 團（主要為羧基）交聯，從而可使該膠黏劑固化且可能降低 其膠㈣度n端視情形而$ ’乳化劑可沈積於壓感 膠層之表面上，從而可能進一步降低膠帶之膠黏強度。 【發明内容】 口此，本發明之一目的係提供即使在基材係聚烯烴基材 時亦具有極佳膠黏性及極佳抗邊緣剝離性且能夠展示適宜 再度捲繞力之壓感膠帶。 本發明之另一目的係提供可作為供束紮用壓感膠帶使用 之壓感膠帶。 127127.doc 200923045 本發明者為達成上述目的堅持不懈地研究。結果，他們 發現，在具有由聚烯烴樹脂構成之基材的壓感膠帶中，當 δ亥壓感膠層係由含有丙烯酸系乳液（其中乳液顆粒具有特 定平均粒徑）之膠黏組合物形成時，則壓感膠帶即使在基 材係聚烯烴基材時亦可具有極佳膠黏性及極佳抗邊緣剝離 性且可藉助適宜之再度捲繞力來再度捲繞。本發明即係基 於該等發現達成。 【實施方式】 具體而言’本發明係關於如下（1)至（5)。 (1) 一種壓感膠帶，其包括基材及配置於該基材至少 一個表面上之至少一壓感膠層， 中《亥基材係由含有聚稀煙樹脂及金屬氮氧化物之烤煙 系樹脂組合物形成，且 其中该壓感膠層係由含有丙烯酸系乳液之乳液型丙烯酸 系踢黏組合物形成’其中乳液顆粒具有〇2微米或更小之 平均粒徑。 (2) 根據（1)之壓感膠帶’其中該乳液型丙烯酸系膠黏 組合物含有如下組份（Α)、及: (A) 乳液型丙烯酸系聚合物， (B) 石油樹脂，及 (C) 松香樹脂， 其中相對於1 〇〇重量份之組份（A)以1至50重量份的比例 含有組份（B)且相對於1〇〇重量份之組份（A)以1至50重量份 的比例含有組份（C)。 127127.doc 200923045 (3) 根據（2)之壓感膠帶，其中該乳液型丙烯酸系聚合 物（A)係藉由含有（曱基）丙烯酸酯及乙烯系不飽和單體之單 體混合物之共聚合獲得之丙烯酸系聚合物，該乙烯系不飽 和單體具有可水解之含矽原子基團。 (4) 根據U)之壓感膠帶，其中該乳液型丙烯酸系聚合 物（A)係藉由在具有可與（曱基）丙烯酸酯共聚合之基團之反 應性乳化劑存在下單體組份之乳液聚合獲得之乳液型丙烯 酸系聚合物。 (5) 根據（2)之壓感膠帶，其中相對於1〇〇重量份之組份 (A)，組份（B)與組份（C)之總比例係1〇至6〇重量份。 在本發明說明書中，（甲基）丙烯酸酯意指丙烯酸酯及/或 甲基丙烯酸酯；且所有"（甲基）"皆以此含義使用。 本發明之壓感膠帶具有上述構成且因此，即使基材係聚 稀煙基材’本發明之壓感膠帶亦可具有極佳膠黏性及極佳 抗邊緣剝離性且可表現出適宜之再度捲繞力。因此，本發 明之壓感膠帶可用作用於束紮之壓感膠帶。另外，在該壓 感膠帶中，基材係聚烯烴基材且因此該膠帶之另一特徵在 於其在焚化時不產生有毒氣體。 壓感膠層 本發明之壓感膠·帶具有由含有丙烯酸系乳液之乳液型丙 烯酸系膠黏組合物形成之壓感膠層，其中乳液顆粒具有 〇-2微米或更小之平均粒徑。為此，在形成壓感膠層之乳 液型丙烯酸系膠黏組合物中之丙烯酸系乳液中，由於乳液 顆粒具有〇 _ 2微米或更小之平均粒徑，因此在乳液顆粒中 127127.doc -10· 200923045 聚合物組合物之分子量（具體而言重量平均分子量）較大， 且因此低分子量組份之比例較小，從而乳液可展示極佳之 凝結力。此乃因當乳液顆粒之粒徑較小時，則乳液中顆粒 之數目變得較大且在-乳液顆粒中所採用聚合起始劑的量 變得較小，且因此在乳液顆粒中聚合物組份之分子量（具 體而言重量平均分子量)變得較大。另外，由於乳液里顆粒 之平均粒徑非常小，因此壓感膠層之表面不粗糙而是平 滑，且因此壓感膠層可確保有效之接觸面積（膠黏面積）。 因此，本發明之壓感膠帶即使基材係烯烴基材亦可展示極 佳膠黏性及極佳抗邊緣剝離性且可展示適宜之再度捲繞 力。 在乳液型丙烯酸系膠黏組合物中，乳液顆粒之平均粒徑 並無特別限制，只要其為0.2微米或更小即可，且較佳為 〇.〇1至0.18微米（更佳為0.08至〇15微米）。乳液型丙烯酸系 膠黏組合物中之乳液顆粒的平均粒徑可使用 Coulter生產之雷射散射衍射粒度儀"LS 13 32〇"加以量測。 乳液型丙烯酸系膠黏組合物並無特別限制，只要其含有 申乳液顆粒具有〇·2微米或更小之平均粒徑之丙烯酸系 乳液即可，且其較佳含有至少一種乳液型丙烯酸系聚合物 (Α)石油樹脂（Β)及松香樹脂（c)，其中石油樹脂（β)之比 例相對於1〇〇重量份之乳液型丙烯酸系聚合物（Α)為1至5〇 重里伤’且松香樹脂（C)之比例相對於1 〇〇重量份之乳液型 丙烯酸系聚合物（Α)為1至5〇重量份。當然，乳液型丙烯酸 ’系聚合物（Α)必須為丙烯酸系乳液形式之丙烯酸系聚合 127127.doc 200923045 物’其中乳液顆粒具有0.2微米或更小之平均粒徑。 如上所述，當石油樹脂（B)及松香樹脂（c)相對於用作膠 黏劑中基礎聚合物之乳液型丙烯酸系聚合物（A)以適宜比 例使用時，則壓感膠帶可展示更優異之膠黏性及更優異之 抗邊緣剝離性且可展示更適宜之再度捲繞力。具體而言， 當膠黏劑以此一適宜比例含有松香樹脂時，則當使用 (例如用其束紮）時，壓感膠帶可展示大為改良之防止膠帶 自其邊剝離之抗邊緣剝離性。於此’抗邊緣剝離性在其用 作用於束紮之壓感膠帶之實際應用中係重要特徵。當膠黏 劑以此一適宜比例含有石油樹脂（B)時，則當再度捲繞時 壓感膠帶之再度捲繞能力可大為改良且該帶可展示適宜之 再度捲繞力，而很少降低或根本不降低其抗邊緣剝離性。 乳液型丙烯酸系聚合物（A) 對於在乳液型丙烯酸系聚合物（A)中之丙烯酸系聚合物 (此可稱為"丙烯酸系聚合物（A)")，可用者係含有（甲基）丙 烯酸酯（丙烯酸酯或甲基丙烯酸酯）作為主要單體組份之（甲

改良聚合物之凝結力及黏附力’因此較佳根據聚合物對象 來使用含官能團之單體。然而’若該類型之單體添加過 多’則其可能使膠黏劑硬化且可能對膠黏特徵有重要影 響。因此，相對於100重量份之丙烯酸系聚合物（A)中之主 要單體組份（甲基）丙烯酸酯（具體而言（甲基）丙烯酸烷基 醋），含官能團之單體的量較佳為3〇重量份或更少，更佳 為10重量份或更少，甚至更佳為5重量份或更少。 127127.doc -15-

體組份（甲基）丙締酸S旨（具體而言（甲基）丙烯酸燒基醋），含 g月匕團之單體的置較佳為5重量份或更少、，更佳為3重量份 或更少，甚至更佳為h5重量份或更少。 在本發明中，丙烯酸系聚合物（A)亦可含有具有可水解 之3石夕原子基團之乙烯系不飽和單體（此可稱為"石夕烧單體 為共聚合單體。換+之，岛 早髖換5之，丙烯酸糸聚合物（A)可具有矽烷 單體之構成單元作為其中之單體組份。此類型之丙稀酸系

INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to pressure-sensitive adhesive tapes. More precisely, it has excellent adhesiveness and excellent resistance to edge peeling even when the substrate is a polyolefin substrate. And can display a pressure sensitive tape suitable for rewinding force. [Prior Art] As a result, the pressure-sensitive adhesive tape (bundle pressure-sensitive adhesive tape) used for tying metal wires (for example, various wires and cables) has been widely used since its ease of operation and flame retardancy. A pressure-sensitive adhesive tape of a polyvinyl chloride resin substrate (hereinafter may be referred to as PVC''). However, since a pressure sensitive tape using pvc generates a toxic gas during incineration, a pressure sensitive tape (this may be called "halogen-free tape") having a plastic substrate containing no halogen atom such as gas has recently been used. In particular, it is a pressure-sensitive adhesive tape having a polyolefin resin composition substrate containing a polyolefin resin as its main component. It is extremely difficult to make the olefinic resin composition as a PVC having a balance of strength, flexibility and stress relaxation properties suitable for the bundle. Therefore, in order to make the smokable resin composition suitable for use as a substrate for a pressure-sensitive adhesive tape for a tying application, various studies have been conducted, for example, regarding the balance of strength and flexibility of the resin composition (see JP_A_2001_192629 or Jp_A_2〇〇). L_ 311061) In other respects, a halogen-free adhesive tape having good adhesion and cohesiveness has been proposed (see JP-A-2001-131509 or JP-A-2001-164215). An aqueous dispersion type adhesive composition containing an acrylic polymer and a decane monomer used as a monomer component thereof has also been proposed (see JP_A_2001-127127.doc 200923045 131511 or JP-A-2003-176469). However, the problem of stress relaxation and relaxation has not been completely solved so far, and since the edge of the pressure-sensitive adhesive tape I may be peeled off after being bundled with the pressure-sensitive adhesive tape having the substrate of the poly-smoke resin composition, the (4) has reliability problems. Since the rewinding force of the pressure-sensitive adhesive tape is too large and the adhesive is caught by the back of the self-adhesive tape, or conversely, when the re-winding force of the pressure-sensitive adhesive tape is small, the tape cannot be used to fasten the wire and the like. 'So it still has other operability issues. As described above, there is no good pressure-sensitive and pure rubber-free pressure-sensitive adhesive tape, which is still not resistant to edge peeling and its easy handling (rewinding force) after being used for stranding to prevent the material from peeling off from the side. As far as practicability is concerned, the rewinding characteristics of the pressure-sensitive adhesive tape which have some influence on its ease of operation 'have been proposed. The rewinding property can be solved by adding a plasticizer to the adhesive. Regarding the edge peel resistance, the adhesiveness of the pressure-sensitive adhesive tape is improved by adding a plasticizer to the base polymer or transferring the plasticizer from the substrate to the base polymer or by adding a tackifier to the base polymer. The method of increasing the adhesiveness is known to us. However, the effect of the specific combination of the plasticizer and the tackifier is not disclosed or proposed. In view of this, in order to solve the problem of the edge peeling resistance and the pressure sensitive tape The present inventors provide an adhesive composition for a pressure-sensitive adhesive tape having a polyolefin substrate composed of a polyolefin resin composition in which a rosin ester tackifier is added, which is an easy-to-operate problem in rewinding. To the adhesive The good tape is resistant to edge peeling, and the rewinding force of the tape is appropriately controlled by the effect of the plasticizer provided to the tape and the oil 127127.doc 200923045. However, 'we hope to have more improved adhesiveness and edge resistance. Peelability and pressure-sensitive adhesive tape with suitable and rewinding force. Specifically, 'in the adhesive composition system containing cross-linking agent, when the cross-linking agent is poorly dispersed in the system (uneven or not uniform) ), or when the drying conditions for forming the pressure-sensitive adhesive layer fluctuate (unstable or a little unstable to the stomach), the rewinding force required in the rewinding pressure-sensitive adhesive tape may increase or be re-rolled There may be some problems with the tape that is wound around the tape. In addition, when the plastic film used as the substrate contains a polyvalent metal salt (such as a metal hydroxide) used as a flame retardant, pressure may occur. The adhesive strength of the adhesive tape may be greatly reduced with time. In addition, it is known that the edge of the tape can be easily peeled off due to this phenomenon, thereby causing the practical problem of the tape. When a polyvalent metal salt is contained in the substrate, the polyvalent metal salt may be crosslinked with a reactive functional group (mainly a carboxyl group) in the base polymer of the adhesive, thereby allowing the adhesive to cure and possibly Reducing the rubber (four) degree n end depending on the situation and the emulsifier can be deposited on the surface of the pressure sensitive adhesive layer, thereby further reducing the adhesive strength of the adhesive tape. [Invention] It is an object of the present invention to provide even The base material is a polyolefin substrate which also has excellent adhesiveness and excellent edge peel resistance and can exhibit a pressure sensitive tape which is suitable for rewinding force. Another object of the present invention is to provide for use as a bundle. The pressure-sensitive adhesive tape used for the pressure-sensitive adhesive tape. 127127.doc 200923045 The present inventors have conducted intensive studies to achieve the above object. As a result, they have found that in a pressure-sensitive adhesive tape having a substrate composed of a polyolefin resin, when δ When the sensitizing layer is formed of an adhesive composition containing an acrylic emulsion in which the emulsion granules have a specific average particle diameter, the pressure-sensitive adhesive tape can have excellent adhesion even when the substrate is a polyolefin substrate. And excellent anti-peeling edge and can be wound again by means of a suitable force to the wound again. The present invention has been achieved based on these findings. [Embodiment] Specifically, the present invention relates to the following (1) to (5). (1) A pressure-sensitive adhesive tape comprising a substrate and at least one pressure-sensitive adhesive layer disposed on at least one surface of the substrate, wherein the substrate is made of a flue-cured tobacco system containing a polysmoke resin and a metal oxynitride The resin composition is formed, and wherein the pressure-sensitive adhesive layer is formed of an emulsion-type acrylic kick-bonding composition containing an acrylic emulsion, wherein the emulsion particles have an average particle diameter of 〇 2 μm or less. (2) The pressure-sensitive adhesive tape according to (1) wherein the emulsion-type acrylic adhesive composition contains the following components (Α), and: (A) an emulsion-type acrylic polymer, (B) a petroleum resin, and C) a rosin resin in which component (B) is contained in a ratio of 1 to 50 parts by weight with respect to 1 part by weight of component (A) and 1 part to 1 part by weight relative to 1 part by weight of component (A) The proportion of 50 parts by weight contains the component (C). 127127.doc 200923045 (3) The pressure-sensitive adhesive tape according to (2), wherein the emulsion-type acrylic polymer (A) is obtained by a monomer mixture containing a (fluorenyl) acrylate and an ethylenically unsaturated monomer. An acrylic polymer obtained by polymerization, the ethylenically unsaturated monomer having a hydrolyzable ruthenium containing group. (4) A pressure-sensitive adhesive tape according to U), wherein the emulsion-type acrylic polymer (A) is a monomer group in the presence of a reactive emulsifier having a group copolymerizable with a (fluorenyl) acrylate An emulsion type acrylic polymer obtained by emulsion polymerization. (5) The pressure-sensitive adhesive tape according to (2), wherein the total ratio of the component (B) to the component (C) is from 1 to 6 parts by weight with respect to 1 part by weight of the component (A). In the specification of the present invention, (meth) acrylate means acrylate and/or methacrylate; and all "(meth)" are used in this sense. The pressure-sensitive adhesive tape of the present invention has the above-described constitution and thus, even if the base material is a dense smoked base material, the pressure-sensitive adhesive tape of the present invention can have excellent adhesiveness and excellent edge peeling resistance and can exhibit a suitable re-degree. Winding force. Therefore, the pressure-sensitive adhesive tape of the present invention can be used as a pressure-sensitive adhesive tape for tying. Further, in the pressure-sensitive adhesive tape, the substrate is a polyolefin substrate and thus another feature of the tape is that it does not generate a toxic gas upon incineration. Pressure-sensitive adhesive layer The pressure-sensitive adhesive tape of the present invention has a pressure-sensitive adhesive layer formed of an emulsion-type acrylic adhesive composition containing an acrylic emulsion, wherein the emulsion particles have an average particle diameter of 〇-2 μm or less. For this reason, in the acrylic emulsion in the emulsion type acrylic adhesive composition forming the pressure-sensitive adhesive layer, since the emulsion particles have an average particle diameter of 〇 2 μm or less, 127127.doc - in the emulsion granules 10· 200923045 The molecular weight of the polymer composition (specifically, the weight average molecular weight) is large, and thus the proportion of the low molecular weight component is small, so that the emulsion can exhibit excellent cohesion. This is because when the particle size of the emulsion particles is small, the number of particles in the emulsion becomes larger and the amount of the polymerization initiator used in the emulsion particles becomes smaller, and thus the polymer group in the emulsion particles The molecular weight (specifically, the weight average molecular weight) of the portion becomes large. Further, since the average particle diameter of the particles in the emulsion is very small, the surface of the pressure-sensitive adhesive layer is not rough but smooth, and therefore the pressure-sensitive adhesive layer ensures an effective contact area (adhesive area). Therefore, the pressure-sensitive adhesive tape of the present invention exhibits excellent adhesiveness and excellent edge peel resistance even if the substrate is an olefin substrate and exhibits a suitable rewinding force. In the emulsion type acrylic adhesive composition, the average particle diameter of the emulsion particles is not particularly limited as long as it is 0.2 μm or less, and preferably 〇1 to 0.18 μm (more preferably 0.08 to 〇 15 microns). The average particle diameter of the emulsion particles in the emulsion type acrylic adhesive composition can be measured using a laser scattering diffraction particle size analyzer "LS 13 32" manufactured by Coulter. The emulsion type acrylic adhesive composition is not particularly limited as long as it contains an acrylic emulsion having an average particle diameter of 2 μm or less, and preferably contains at least one emulsion type acrylic polymerization. (石油) petroleum resin (Β) and rosin resin (c), wherein the ratio of petroleum resin (β) is 1 to 5 〇 in weight with respect to 1 part by weight of the emulsion type acrylic polymer (Α) The proportion of the rosin resin (C) is 1 to 5 parts by weight based on 1 part by weight of the emulsion type acrylic polymer (Α). Of course, the emulsion type acrylic polymer (Α) must be an acrylic polymerization in the form of an acrylic emulsion 127127.doc 200923045' wherein the emulsion particles have an average particle diameter of 0.2 μm or less. As described above, when the petroleum resin (B) and the rosin resin (c) are used in an appropriate ratio with respect to the emulsion type acrylic polymer (A) used as the base polymer in the adhesive, the pressure-sensitive adhesive tape can exhibit more Excellent adhesiveness and superior edge peel resistance and can display a more suitable rewinding force. Specifically, when the adhesive contains the rosin resin in an appropriate ratio, the pressure-sensitive adhesive tape can exhibit a greatly improved anti-edge peeling property for preventing the tape from peeling off from the side when used (for example, by bundling). . Here, the anti-edge peeling property is an important feature in the practical application of the pressure-sensitive adhesive tape which acts on the bundle. When the adhesive contains the petroleum resin (B) in an appropriate ratio, the rewinding ability of the pressure-sensitive adhesive tape can be greatly improved when re-winding, and the belt can exhibit a suitable rewinding force, and rarely It reduces or does not reduce its resistance to edge peeling. Emulsion type acrylic polymer (A) For the acrylic polymer in the emulsion type acrylic polymer (A) (this can be called "acrylic polymer (A)"), it is available (A) A (meth)acrylic acid vinegar polymer having a acrylate (acrylate or methacrylate) as a main monomer component. (Methyl) acrylate vinegar includes alkyl (meth) acrylates as described below and cycloalkyl (meth) acrylates such as cyclohexyl (meth) acrylate and phenyl (meth) acrylate An ester or the like (mercapto) aryl acrylate. The acrylic polymer (A) preferably contains an alkyl (meth)acrylate polymer having a (meth)acrylic acid alkyl group as a main monomer component. The (meth)acrylic acid alkyl ester polymer may be a single polymer (homopolymer) of alkyl (meth)acrylate or an alkyl (meth)acrylate and a cyclic ring such as (fluorenyl)acrylic acid. 127127.doc -12- 200923045 Any other (meth) acrylate such as ester or aryl (meth) acrylate or any other monomer copolymerizable with alkyl (meth) acrylate (copolymerized monomer) Copolymer. In other words, in the (meth)acrylic acid alkyl ester polymer, the monomer component such as an alkyl (meth)acrylate may be used singly or in combination of two or more of such monomers. Examples of the alkyl (meth)acrylate in the acrylic polymer (A) include Cw alkyl acrylate (preferably c2_14 (meth) acrylate alkyl hydrazine is more preferably C2_10 ( Methyl)alkyl acrylates, such as decyl (meth) acrylate, ethyl (meth) acrylate, propyl (meth) acrylate, isopropyl (meth) acrylate, Butyl methyl methacrylate, isobutyl (meth) acrylate, second butyl (meth) acrylate, t-butyl methacrylate (meth) acrylate, pentyl (meth) acrylate, ( Methyl)hexyl acrylate, heptyl (meth)acrylate, octyl (meth)acrylate, 2-ethylhexyl (meth)acrylate, isooctyl (meth)acrylate, (methyl) Nonyl acrylate, isodecyl (meth) acrylate, decyl (meth) acrylate, isodecyl (meth) acrylate, undecyl (decyl) acrylate, (methyl) propyl Dilute dodecyl ester, tridecyl (meth)acrylate, (meth)acrylic acid Alkyl ester, pentadecyl (meth)acrylate, cetyl (meth)acrylate, heptadecyl (meth)acrylate, octadecyl (meth)acrylate, (A) Base) hexadecyl acrylate and eicosyl (meth) acrylate. The alkyl (meth)acrylate is more preferably butyl (meth)acrylate or 2-ethylhexyl (meth)acrylate. (Meth) acrylate used herein as the main monomer component 'and relative to the total amount of the monomer component, (meth) acrylate (specifically, (meth) acrylate 127127.doc -13· 200923045 The proportion of the base ester) is preferably 5% by weight or more, preferably 8% by weight or more, and more preferably 90% by weight or more. When the proportion of (meth) acrylate is less than 50% by weight, the adhesiveness and cohesiveness (or adhesive strength and coagulation ability) of the adhesive composition may be lowered. In the acrylic polymer (A), a co-monomer copolymerizable with an alkyl (meth)acrylate includes, for example, a carboxyl group-containing monomer such as (meth)acrylic acid (propionic acid or methylpropyl).

As the copolymerizable monomer, a monomer having a functional group is preferred, and a monomer having an acidic functional group (especially a monomer having a carboxyl group such as (meth)acrylic acid) is more preferred. The copolymerizable monomers may be used singly or in combination of two or more kinds thereof. Since a functional group-containing monomer (e.g., an acid functional group-containing monomer) can effectively improve the cohesive force and adhesion of the polymer, it is preferred to use a functional group-containing monomer depending on the polymer object. However, 'if this type of monomer is added too much' it may harden the adhesive and may have an important effect on the adhesive characteristics. Therefore, the amount of the functional group-containing monomer is relatively larger than 100 parts by weight of the main monomer component (meth) acrylate (specifically, alkyl (meth) acrylate) in the acrylic polymer (A). It is preferably 3 parts by weight or less, more preferably 10 parts by weight or less, even more preferably 5 parts by weight or less. 127127.doc -15- 200923045 In the present invention, when an acrylic polymer (A) containing a functional group-containing monomer as a monomer component is applied to a polyvalent metal salt (for example, magnesium hydroxide or aluminum hydroxide) On the polyolefin substrate, the ionized metal salt can react with the functional group in the acrylic polymer (A) to promote crosslinking of the adhesive, and therefore attention should be paid to this. Therefore, although this end depends on the type of the substrate, in this case, when a polyolefin substrate containing a polyvalent metal salt is used as a support, it is mainly related to 100 parts by weight of the acrylic polymer (A). The monomer component (methyl) propionate S is intended to be specifically (specifically, (meth)acrylic acid vinegar), and the monomer containing the g gangrene group is preferably 5 parts by weight or less, more preferably It is 3 parts by weight or less, and even more preferably h5 parts by weight or less. In the present invention, the acrylic polymer (A) may further contain an ethylenically unsaturated monomer having a hydrolyzable 3 austenite group (this may be referred to as a "combination monomer". In the case of the island, the yttrium acrylate polymer (A) may have a constituent unit of a decane monomer as a monomer component therein. The acrylic acid polymer of this type (8) has at least one molecule in the molecule. The hydrolyzable group containing the cerium atom can be easily and stably prepared by using the ceramsite-containing monomer 1 and the hydrolyzable group containing the cerium atom can be uniformly or uniformly homogenized. It is introduced into a smear. Therefore, when the celestial precursor is used as a copolymerization monomer, the pressure-sensitive adhesive layer can be copolymerized by the group introduced into the acrylic acid polymer (4) by condensation without being smashed. In the storm...cup...the parent is not added to it. Therefore, the dusty adhesive layer which is stable and good in production quality is affected by the dispersibility of the crosslinking agent, and it does not affect the condition. Drying may be fluctuating in the dryness in the decane monomer, hydrolyzed containing ruthenium, base Examples of the group include a carboxyalkyl group having 1 127127.doc -16 - 200923045 to 3 alkoxy groups, such as a trialkoxycarbenyl group, such as a trimethoxymethyl decyl 'triethoxy decyl group, three Propyl methoxyalkyl, triisopropoxy methoxyalkyl, tributoxymethyl decyl or triisobutyloxy decyl; dialkyloxyalkyl carboxyalkyl, such as dimethoxymethyl Carboxyalkyl, dimethoxyethyl formyl, dimethoxypropyl formyl, dimethoxy isopropyl carbenyl, dimethoxy methoxy carboxyalkyl, diethoxymethyl a decyl group, a diethoxyethyl formamyl group, a diethoxypropyl decyl group, a diethoxy isopropyl carbaryl group or a diethoxy butyl decyl group, and an alkoxydialkyl group A ketone group, such as methoxydimethylformamyl, methoxydiethylformamidinyl, methoxydipropylmethyl sulfonyl, methoxydiisopropyl ruthenium , methoxydibutyl phthalocyanine, ethoxy dimethyl fluorenyl, ethoxydiethyl decyl, ethoxydipropyl methacrylate Ethoxydiisopropylmethytyl or ethoxydibutylformamidin. In the case where the alkyl group having an alkoxy group has a plurality (2 or 3) alkoxy groups, then the plural The methoxy groups may all be the same or may be partially the same or may be all different. In the case where the methoxyalkyl group having an alkoxy group has two groups other than an alkoxy group (for example, an alkyl group), the other groups are It may be the same or different. In the present invention, as a decane monomer, in view of its excellent copolymerization ability with (mercapto)acrylic acid vinegar (specifically, mercapto acrylate), preferred a decane compound having an ethylenically unsaturated bonding site and having a hydrolyzable aragonite atom group, such as a (meth) propylene oxyalkyl group, a vinyl decane derivative, a vinyl alkyl decane Derivatives. 127127.doc -17- 200923045 Examples of (meth) propylene decyloxyalkyl decane derivatives include the following cerium oxide compounds: 曱矽 曱矽 alkyl groups having 丨 to 3 alkoxy groups The extension group is bonded to the (fluorenyl) propylene oxy group (C) a methoxy or methyl propyl oxime); and specific examples thereof include (meth) propylene oxyalkyl-tritoxy decane, (fluorenyl) propylene oxyalkyl-ditoxy _alkyl decane and (meth) propylene methoxyalkyl-alkoxy dialkyl decane.

During the polymerization (for example, emulsion polymerization), the monomer component can be introduced into the reaction system by supplying it all to the reaction system in advance or by supplying it continuously or intermittently; or One portion of the component may be supplied all at once to the reaction system, and the remainder thereof may be added dropwise to the system continuously or intermittently to thereby introduce the monomer component into the reaction system. In other words, the polymerization mode of the emulsion polymerization may be any one of ordinary bulk polymerization, continuous dropwise addition polymerization, or intermittent dropwise addition polymerization. The polymerization can be achieved step by step. Specifically, for example, another monomer component may be added thereto after performing one polymerization to further carry out other polymerization. In the emulsion type acrylic polymer (Α) of the present invention, as described above, the emulsion particles of the acrylic polymer have an average particle diameter of 〇 2 μm or less; and therefore, emulsion polymerization is carried out so that the formed emulsion particles are formed It may be important to have an average particle size of 〇 2 microns or less. Therefore, the emulsion type acrylic polymer (Α) can be produced by emulsion polymerization under conditions capable of producing emulsion particles having an average particle diameter of 0.2 μm or less.

For example, the relationship between the amount of the emulsifier (parts by weight, relative to 100 parts by weight of the acrylic polymer to be obtained) and the average particle diameter of the emulsion particles in the acrylic emulsion may be as follows: amount of emulsifier (weight fraction average) Particle size (micron) =

In the emulsion polymerization of the overall polymerization mode, in view of the effect of temperature control and increase in molecular weight of the polymer, it is effective to employ a method comprising a temperature lower than a predetermined reaction initiation temperature of the polymerization initiator (for example, 8 〇 _ 9〇<t, preferably about 85. The emulsified monomer component is polymerized under the arm and the reaction temperature is gradually increased. On the other hand, in the emulsion polymerization in which the continuous dropwise addition polymerization method is employed, the following method can be employed. The emulsified monomer component is added dropwise to the aqueous system to which the emulsifier has been previously added. Specifically, the emulsifier is 0.05/1 relative to the propylene (tetra) polymer to be obtained (preferably The ratio of 〇·1/〇·5) is added to the aqueous system (aqueous phase), and thus an acrylic emulsion in which the emulsion particles have an average particle diameter of Q 2 μm or less can be prepared. In this case, when When the droplet velocity of the bulk component is increased, the average particle diameter of the polymer may be small; and when the amount of the emulsifier previously supplied to the aqueous phase is increased, the average particle diameter of the polymer may be small. , # is controlled by the appropriate drip rate of the monomer component and The amount of the emulsifier supplied first to the aqueous phase can control the average particle diameter of the polymer to be produced.

The temperature during the polymerization can be appropriately determined depending on the type of the initiator used, and for example, it can be from 2〇t to 100. When preparing an emulsion type acrylic polymer by emulsion polymerization, one or more known emulsifiers may be used singly or in combination thereof. However, in order to prevent or prevent deposition of an emulsifier on the surface of the pressure sensitive adhesive layer ( The adhesive strength of the low-pressure adhesive layer or the emulsifier may contaminate the object applied by the pressure-sensitive adhesive tape, and the emulsifier that is expected to be used herein has the ability to react with bismuth acrylate. a reactive emulsifier of a group such as a group having an ethylenically unsaturated bonding site. The reactive emulsifier can be bonded to a molecular chain in the adhesive composition (specifically to an acrylic polymer ( A) The molecular chain), and thus preventing or preventing deposition or transfer onto the surface of the pressure-sensitive adhesive layer. Therefore, the adhesive strength of the pressure-sensitive adhesive layer can be effectively prevented or prevented from decreasing with time and the pressure feeling can be effectively prevented or prevented. The adhesive to which the tape is applied is contaminated with time. Therefore, it is desirable for the emulsion type acrylic polymer (A) to be prepared by emulsion polymerization of a monomer component in the presence of a reactive ritual agent.

For example, when a thick polyolefin substrate or a hard (tetra) hydrocarbon substrate is used, since the edge peeling resistance of the pressure sensitive tape may be lowered, it is desirable that the ratio of the rosin resin (C) is higher within the above range, whereby The pressure sensitive tape can have good edge peel resistance. On the other hand, when a thin polyolefin substrate or a relatively soft polyolefin substrate which is advantageous for edge peel resistance is used, the total amount of the petroleum resin (B) and the rosin resin (c) can be reduced. Further, when the rewinding force of the pressure-sensitive adhesive tape is small, the amount of the petroleum resin (B) can be increased within the above range, thereby increasing the force, and thus, the pressure-sensitive adhesive tape can thereby exhibit a suitable re-degree Winding force. Emulsion-type acrylic acid-based adhesive composition The emulsion-type acrylic-based adhesive composition in the present invention may contain a plasticizer. Plasticizers are optional ingredients in the composition. By adding a plasticizer to the emulsion type acrylic adhesive composition, when the emulsion type acrylic adhesive composition is used to form the pressure sensitive adhesive layer of the pressure sensitive adhesive tape of the present invention, the plasticizer may migrate to The polyolefin substrate thus exhibits the effect of softening the polyolefin substrate. Therefore, the polyolefin substrate is softened and the edge peel resistance of the pressure-sensitive adhesive tape can be improved thereby. From this point of view, the edge peel resistance of the pressure sensitive tape can be further improved by adding a plasticizer to the adhesive. Examples of plasticizers 127127.doc • 31 - 200923045 which may be used herein include phthalate plasticizers (e.g., dibutyl phthalate (DBP), diheptyl phthalate ( DHp), dioctyl phthalate (DOP), diisononyl phthalate, diisononyl phthalate (DIDP), tridecyl phthalate (DTDp) ) diisotridecyl acid ester, butyl butyl phthalate lauryl ester and butyl phthalate benzyl ester) and trimellitic acid ester plasticizer (eg trimellitic acid II) Octyl ester (TOTM) and tri-n-octyl trimellitate). It is not limited to these and can also be used in the present invention as a fatty acid plasticizer (for example, tributyl citrate, dioctyl adipate (D〇A), dioctyl sebacate (DOZ). ), dioctyl sebacate (D〇s) and decyl phthalate), phosphate plasticizers (such as tricresyl phosphate (TCp) and trioctyl phosphate (TOP) ), epoxy resin plasticizer and polyester plasticizer. These plasticizers may be used alone or in combination of two or more kinds thereof. Although the amount of the plasticizer is not particularly limited, when it is excessively added, the adhesive may be softened to cause an adhesive which cannot be adhered or is liable to remain. Therefore, for 1 part by weight of the emulsion type acrylic polymer (4), the plasticizer is preferably 30 parts by weight or less (e.g., 13 G parts by weight). When the plasticizer 1 is too small, the effect of the plasticizer to soften the polyolefin substrate may be lowered. The liquid form of the bupropion acid-based adhesive composition may contain a crosslinking agent. The crosslinking agent is overlaid and the examples include an epoxy resin crosslinking agent, an oleic acid vinegar, and a ruthenium (tetra) crosslinking agent. These crosslinking agents may be used alone or in combination of two or more. There is no particular limitation on the amount of the product which can be used in the adhesive composition. In addition, the 'emulsion type acrylic adhesive composition may contain any tackifying resin different from 127127.doc -32- 200923045 oleoresin (B) and rosin resin (C) (for example, bismuth-based tackifying resin, cumbersome The adhesive resin, the epoxy resin tackifying resin, the polyamine amine tackifying resin, the ketone tackifying resin, and the elastomer-based tackifying resin can be used as long as the effect of the present invention is not impaired. In the present invention, the emulsion type acrylic adhesive composition may contain various additives (if necessary). The additives may be selected from known additives such as the above plasticizers (softeners), tackifying resins and crosslinked resins, as well as viscosity modifiers, UV absorbers, antioxidants, fillers, colorants, antistatic agents, foaming agents. And surfactants. The emulsion type acrylic adhesive composition can be obtained, for example, by using the above emulsion type acrylic polymer (A), petroleum resin (B), and rosin resin (c) and (as appropriate) a plasticizer and a crosslinking agent. Other additives are prepared by mixing. Substrate The pressure-sensitive adhesive tape of the present invention comprises a polyolefin substrate formed of a poly-sparse resin composition containing a polyolefin resin and a metal hydroxide. Examples of the polyolefin resin in the polyolefin substrate include polyolefin resins containing an α-olefin as a monomer component thereof, such as polyethylene (ruthenium), polypropylene (ruthenium), ethylene-propylene copolymer, and ethylene-acetic acid. Vinyl ester copolymer (EVA). These polyolefin resins may be used singly or in combination of two or more kinds thereof. In the present invention, the substrate is preferably a polyolefin substrate substantially free of a _ atom. The term "quoting" as used herein does not substantially contain a _ atom, and means that a substance containing a (tetra) atom in the molecule is not used as a material constituting the smoky base material (olefin resin composition). Therefore, when the composition of the substrate is analyzed by an analyzer, a trace amount of a halogen atom is detected in the substrate material (for example, 127127.doc-33-200923045, for example, a substance containing a halogen atom in a constituent material for producing a substrate) It is acceptable that a halogen atom generated as a catalyst is mixed in a constituent material of the substrate, and thus a trace amount of a nitrogen atom is detected in the substrate. More specifically, examples of the polyolefin resin in the polyanthracene base material include polyethylene (for example, low density polyethylene #, linear low density polyethylene, ultra low density polyethylene, medium density polyhexene, and high density poly Ethylene), polypropylene, polybutene and polybutadiene and copolymers of ethylene and/or propylene with any other heart olefin (especially random copolymers), such as ethylene-propylene copolymers (random copolymers) .

The other resin is a thermoplastic resin having a carbonyl oxygen atom in a molecule (molecular skeleton) from the viewpoint of a suitable flexibility of the substrate. As the thermoplastic resin having a carbonyl oxygen atom (oxygen atom assigned to a carbonyl group) in the molecule, a soft polyolefin resin having a plurality of oxygen atoms in the molecule (this may be referred to as a 'carbonyl group-containing polyolefin resin') is preferred. Of course, since the carbonyl-containing polyolefin is a polyolefin resin, it can be used as a polyolefin resin which functions as a constituent material of the pressure-sensitive adhesive tape substrate. In other words, the carbonyl-containing polyolefin resin can be used alone or in combination with any other. A polyolefin resin is used as a polyolefin resin for a substrate. Preferred examples of the carbon-based polyolefin resin include a vinyl copolymer having a carbonyl group or a metal salt thereof (ionomer) using ethylene and a vinyl riding compound And/or an α,β·unsaturated carboxylic acid or a derivative thereof (for example, an anhydride, an ester or a vapor) is produced as a monomer component thereof.
