Description
本発明は、ポリオール、ポリイソシアネート、希釈剤、セメント、骨材及び水を含有してなる塗床用水硬性ポリマーセメント組成物にその施工時に添加して硬化を促進する塗床用水硬性ポリマーセメント組成物の硬化促進剤組成物に関する。 The present invention relates to a hydraulic polymer cement composition for flooring which is added to a hydraulic polymer cement composition for flooring which contains polyol, polyisocyanate, diluent, cement, aggregate and water, and accelerates hardening by its construction. It relates to a curing accelerator composition.
塗床用水硬性ポリマーセメント組成物は、熱水による洗浄を高頻度で行ない且つ年中無休状態で稼動する食品工場床等の下地コンクリート上に直接塗付され硬化して塗り床と成るものであるが、特に冬季の１５℃以下の低温時に施工すると硬化が遅延し、施工翌日にも硬化が不十分となって床として使用できない場合があるという課題がある。 The hydraulic polymer cement composition for flooring is coated directly on the ground concrete such as a food factory floor that is frequently washed with hot water and operates 24 hours a day, and becomes a coated floor. However, when it is constructed at a low temperature of 15 ° C. or lower especially in winter, there is a problem that the curing is delayed and the next day of construction is insufficiently cured and cannot be used as a floor.
これに対して、実用上十分な可使時間を持ち、低温硬化性に優れる硬化性ポリマーセメント組成物が提案されている。該硬化性ポリマーセメント組成物は、ポリオール、触媒、ポリイソシアネート、セメント、骨材及び水を含有して成る硬化性ポリマーセメント組成物において、触媒としてイミダゾール化合物及びジモルホリノジエチルエーテルを用いることを特徴とする硬化性ポリマーセメント組成物である（特許文献１参照）。 On the other hand, a curable polymer cement composition having a practically sufficient pot life and excellent low-temperature curability has been proposed. The curable polymer cement composition is characterized by using an imidazole compound and dimorpholinodiethyl ether as a catalyst in a curable polymer cement composition comprising a polyol, a catalyst, a polyisocyanate, a cement, an aggregate, and water. It is a curable polymer cement composition (see Patent Document 1).
また、良好な仕上がり外観を与えるポリウレタン系セメント組成物として、（ａ）水硬性セメント、（ｂ）骨材、（ｃ）イソシアネート基を含む化合物、（ｄ）水、（ｅ）３級アミン化合物触媒、および（ｆ）活性水素含有化合物（ただし水および３級アミン化合物触媒を除く）、を必須成分とするポリウレタン系セメント組成物が提案されている（特許文献２参照）。 Further, as a polyurethane-based cement composition that gives a good finished appearance, (a) hydraulic cement, (b) aggregate, (c) a compound containing an isocyanate group, (d) water, (e) a tertiary amine compound catalyst A polyurethane-based cement composition containing, as an essential component, and (f) an active hydrogen-containing compound (excluding water and a tertiary amine compound catalyst) has been proposed (see Patent Document 2).
しかしながら、特許文献１及び特許文献２に記載の３級アミン化合物、イミダゾール化合物、ジモルホリノジエチルエーテルを使用すると、十分な硬化促進効果が得られない場合があり、また可使時間が短くなって施工が出来なくなる場合があるという課題がある。 However, when the tertiary amine compound, imidazole compound, and dimorpholinodiethyl ether described in Patent Document 1 and Patent Document 2 are used, a sufficient curing accelerating effect may not be obtained, and the pot life is shortened. There is a problem that it may not be possible.
本発明が解決しようとする課題は、１５℃以下のいずれの温度下においても、材料を混合後に下地コンクリート上に施工可能な所謂可使時間を十分に有すると共に８時間以内に硬化して塗り床として使用が可能となり、硬化後の塗膜（塗り床）に炭酸ガス等による膨れ、発泡（ピンホール）がなく、さらには塗膜（塗り床）の性能が低下することがない、塗床用水硬性ポリマーセメント組成物の硬化促進剤組成物及び硬化促進方法を提供することにある。 The problem to be solved by the present invention is to have a so-called pot life that can be applied on the foundation concrete after mixing the materials at any temperature of 15 ° C. or less and harden within 8 hours to be coated. The coating film (coating floor) after curing does not swell due to carbon dioxide gas, foam (pinhole), and the performance of the coating film (coating floor) does not deteriorate. It is in providing the hardening accelerator composition and hardening acceleration | stimulation method of a hard polymer cement composition.

Can be attached. The alkyl sulfonic acid ester compound is a non-phthalic acid plasticizer, and mezamol (trade name, 100% alkyl sulfonic acid ester compound, manufactured by Bayer) is a commercially available product. The adipic acid ester is preferably diisononyl adipate. It is preferable that the polyol, diluent and water are mixed to form one liquid and formed as the main agent.

[Adhesiveness]
On the surface of a dried concrete flat plate of 300 mm x 300 mm x 60 mm thick (display value of 5% or less in the Ket Moisture Meter HI-520 concrete range) of JISA5371 at 23 ° C, the coating floor of Examples, Comparative Examples and Reference Examples Hydraulic polymer cement composition for use (including curing accelerator composition for Examples and Comparative Examples), 4 mm thickness on foundation concrete except for Example 4, Example 5, Example 6 and Reference Example 2 Spread and spread for 7 days to give a test specimen. About Example 4, Example 5, Example 6, and Reference Example 2, the surface is smoothed and pressed for 7 days on a ground concrete with a mallet or the like, and cured for 7 days. The adhesion strength (N / mm 2 ) between the 40 × 40 mm portion of the hydraulic polymer cement composition for coating and the concrete flat plate was measured with a Kenken-type adhesive strength tester. As for the fracture state, 100% cohesive fracture of the ground concrete was evaluated as “good”, and the others were evaluated as “poor”.
