Abstract
Description
本発明は、シリル基またはシロキシ基に起因した特性およびアンモニウム塩の特性を兼ね備えた新規なシロキシ基含有トリアルキルアンモニウムオリゴマー類およびその製造方法並びにこれを有効成分とする抗菌活性に優れる抗菌性樹脂組成物に関するものである The present invention relates to novel siloxy group-containing trialkylammonium oligomers having characteristics derived from silyl groups or siloxy groups and ammonium salts, a method for producing the same, and an antibacterial resin composition having excellent antibacterial activity using the same as an active ingredient About things
樹脂、光学材料、塗料等の分野で用いられている塗工液には、部材表面への塗工工程で発生するスジ、ハジキ、ムラ、ブツ、不濡れ等の不良の抑制、即ち、塗工膜表面への平滑性の付与を目的として、様々な物質が添加されている。 Coating liquids used in the fields of resins, optical materials, paints, etc., suppress defects such as streaks, repellency, unevenness, irregularities, and non-wetting that occur during the coating process on the surface of the member. Various substances are added for the purpose of imparting smoothness to the film surface.
パーフルオロアルケニル基を含有する化合物も本用途での添加剤として用いられており、特に、表面平滑性付与の点で、パーフルオロアルケニル基を有するノニオン系界面活性剤が有用であることが知られている(例えば、特許文献1)。 A compound containing a perfluoroalkenyl group is also used as an additive in this application, and in particular, a nonionic surfactant having a perfluoroalkenyl group is known to be useful in terms of imparting surface smoothness. (For example, Patent Document 1).
また、薄型ディスプレイ、PCモニター、携帯電話、携帯ゲーム機、カーナビゲーション等は様々な環境で使用され、タッチパネル化が進んでいる。これらの機器の画面では特に、画面表面に皮脂や化粧品、飲食物のカス等の様々な汚れが付着し、菌の繁殖を促進する。皮脂や化粧品、飲食物のカス等の汚れを除去するために、水や洗剤を含ませた布等による拭き取りが行われるが、汚れの拭き取りは容易ではなく、何度も拭き取りを行うことにより、画面に擦傷痕が生じることもある。 Thin displays, PC monitors, mobile phones, portable game machines, car navigation systems, etc. are used in various environments, and touch panels are being developed. Especially on the screens of these devices, various stains such as sebum, cosmetics, and food wastes adhere to the screen surface and promote the growth of bacteria. In order to remove dirt such as sebum, cosmetics, food waste, etc., wiping with a cloth soaked in water or detergent is performed, but wiping off the dirt is not easy, by wiping it many times, There may be scratch marks on the screen.
菌の繁殖を抑える目的で、抗菌剤を導入する方法が知られており、幅広く利用されている(例えば、特許文献2および3)。従来から所望の材料に抗菌性を付与する為に種々の抗菌剤が開発されており、有機系と無機系の抗菌剤が知られている。有機系の抗菌剤として、塩化ベンザルコニウムなどの第四アンモニウム塩系化合物、2,4−チアゾリルベンズイミダゾールなどのイオウ含有ベンズイミダゾール系化合物、メチレンビスチオシアネートなどのビスチオシアネート系化合物、8−キノリノールなどのキノリノール系化合物、エタノールなどのアルコール系化合物、ホルマリンなどのアルデヒド系化合物、クレゾールなどのフェノール系化合物、ソルビン酸などのカルボン酸系化合物などの抗菌剤が知られている。一方、無機系の抗菌剤として、銀、銅、亜鉛などの抗菌性を示す金属イオンを活性炭、アパタイト、ゼオライト、四価金属燐酸塩などに担持させたものが知られている。 Methods for introducing antibacterial agents are known and widely used for the purpose of suppressing the growth of bacteria (for example, Patent Documents 2 and 3). Various antibacterial agents have been developed so far to impart antibacterial properties to desired materials, and organic and inorganic antibacterial agents are known. Organic antibacterial agents include quaternary ammonium salt compounds such as benzalkonium chloride, sulfur-containing benzimidazole compounds such as 2,4-thiazolylbenzimidazole, bisthiocyanate compounds such as methylenebisthiocyanate, 8- Antibacterial agents such as quinolinol compounds such as quinolinol, alcohol compounds such as ethanol, aldehyde compounds such as formalin, phenol compounds such as cresol, and carboxylic acid compounds such as sorbic acid are known. On the other hand, known inorganic antibacterial agents are those in which metal ions exhibiting antibacterial properties such as silver, copper, and zinc are supported on activated carbon, apatite, zeolite, tetravalent metal phosphate, and the like.
しかしながら、シロキシ基を有する界面活性剤は表面の平滑性およびスリップ性、濡れ性等は得られるものの、抗菌性は無いという問題があった。 However, the surfactant having a siloxy group has a problem that it has antibacterial properties although it can obtain surface smoothness, slip property, wettability and the like.
また、従来の有機系抗菌剤は一般に耐熱性に乏しい為、プラスチックや繊維などへの練り込み加工に使用すると、変色、発泡などの問題を起こしたり、加工時に揮発や分解を生じ、充分な抗菌効果を発揮できなかった。さらに、プラスチックや樹脂等へ抗菌性を付与する為には、多量の抗菌剤を必要とし、元来持っているプラスチックや樹脂の性能を低下させるという問題があった。また、有機系抗菌剤は樹脂液中の硬化成分と化学的に結合しないため、時間の経過や外部からの刺激により樹脂硬化膜中から抜け、効果が消失してしまう。さらに、膜中で可塑剤的作用を示し、膜強度を低下させるといった問題点がある。 Also, since conventional organic antibacterial agents generally have poor heat resistance, when used for kneading into plastics or fibers, problems such as discoloration and foaming occur, and volatilization and decomposition occur during processing, resulting in sufficient antibacterial properties. The effect could not be demonstrated. Furthermore, in order to impart antibacterial properties to plastics and resins, a large amount of antibacterial agents are required, and there is a problem in that the performance of the inherent plastics and resins is lowered. In addition, since the organic antibacterial agent does not chemically bond with the curing component in the resin liquid, the effect is lost due to removal from the cured resin film due to the passage of time or external stimulus. Furthermore, there is a problem that it exhibits a plasticizer action in the film and lowers the film strength.
従来の無機系抗菌剤は耐熱性や耐薬品性に優れているものの、比較的高価であること、加工が難しいこと、加工時や使用時に着色や変色の可能性があること、効果の再現性に劣ることなどの問題点があった。加えて、無機系抗菌剤を使用した場合、透明な抗菌性付与面を得ることが難しかった。 Conventional inorganic antibacterial agents have excellent heat resistance and chemical resistance, but are relatively expensive, difficult to process, and may be colored or discolored during processing or use, and reproducibility of effects There were problems such as inferiority. In addition, when an inorganic antibacterial agent is used, it is difficult to obtain a transparent antibacterial imparting surface.
従って本発明は、基材の性能を損なうことのない抗菌組成物であり、且つ抗菌性付与面の透明性も兼ね備えた抗菌性組成物を提供することを目的とする。 Accordingly, an object of the present invention is to provide an antibacterial composition that does not impair the performance of the substrate and also has transparency of the antibacterial property imparting surface.

It has been found that it is possible to continuously impart antibacterial properties and antibacterial properties and transparency. These findings led to the development of antibacterial oligomers that have both excellent antibacterial effect and transparency when cured and do not affect film strength. By making it an oligomer type antibacterial agent, it is characterized by an increase in the density of antibacterial active groups based on the properties of the polymer, a reduction in toxicity by increasing the molecular size, and an approach as an oligomer material.

抗菌性の評価
(1)抗菌性
評価基準 : ◎ = 菌の生育なし
○ = コロニー数1〜50
△ = コロニー数が50以上であるが、未添加と比較して抗菌効果が見られる
× = 未添加樹脂組成物と同等以下、抗菌効果が見られない
(2)透明性
試験片の透明性を目視で観察した。
Antibacterial Evaluation (1) Antibacterial Evaluation Criteria: ◎ = No growth of bacteria
○ = 1-50 colonies
△ = The number of colonies is 50 or more, but the antibacterial effect is seen compared with the non-added
× = Less than or equal to unadded resin composition, no antibacterial effect seen
(2) Transparency The transparency of the test piece was visually observed.
評価基準 : 透明 = ○
濁りあり = ×
(3)塗膜硬度
JIS K 5600-5-4に準じて、試験塗板面に対し約45°の角度に鉛筆の芯を当て、750g荷重で試験塗板面に押し付けながら前方に均一な速さで約10mm以上動かした。塗膜が破れなかったもっとも硬い鉛筆の硬度記号を塗膜硬度とした。

表2から分かるように、本発明の抗菌性組成物は、抗菌性に優れ、透明性にも優れている。 As can be seen from Table 2, the antibacterial composition of the present invention has excellent antibacterial properties and excellent transparency.
樹脂を変更しても、添加剤を入れることでスジやハジキの抑制が出来、シロキシ基含有トリメチルアンモニウムオリゴマーを添加することにより抗菌性が発現する。また、無機系抗菌剤の使用では樹脂組成物の透明性がなくなるが、合成例1〜7のシロキシ基含有トリメチルアンモニウムオリゴマーでは、抗菌性能および透明性に優れている。さらに、比較例4では抗菌性も透明性もあるが塗膜性能が落ちてしまっていたが、シロキシ基含有トリメチルアンモニウムオリゴマーの使用で塗膜性能を維持したまま、抗菌性、透明性が得られる。 Even if the resin is changed, streaks and repelling can be suppressed by adding an additive, and antibacterial properties are exhibited by adding a siloxy group-containing trimethylammonium oligomer. Moreover, although the transparency of the resin composition is lost when an inorganic antibacterial agent is used, the siloxy group-containing trimethylammonium oligomers of Synthesis Examples 1 to 7 are excellent in antibacterial performance and transparency. Further, in Comparative Example 4, although the antibacterial property and transparency are both present, the coating film performance has been lowered, but the antibacterial property and transparency can be obtained while maintaining the coating film performance by using the siloxy group-containing trimethylammonium oligomer. .
本発明による、シロキシ基含有トリメチルアンモニウムオリゴマーは、例えば、ガラス、繊維、金属、樹脂、フィルム、光学材料、塗料等の分野で用いられる抗菌性付与剤として有用であり、基材表面に抗菌性、透明性、帯電防止性を付与させることができる化合物として有用である。 The siloxy group-containing trimethylammonium oligomer according to the present invention is useful, for example, as an antibacterial property-imparting agent used in the fields of glass, fibers, metals, resins, films, optical materials, paints, etc. It is useful as a compound that can impart transparency and antistatic properties.
