本文采用溶液聚合的方法[1],以丙烯酸酯和聚氨酯101-乙组分为原料,合成了玻璃化温度为-48℃的溶液型丙烯酸酯压敏胶黏剂。讨论了单体组成以及单体中丙烯酸羟乙酯与固化剂的比例大小等因素对胶黏剂性能的影响。结果表明,当丙烯酸羟乙酯与固化剂比例为2∶1,反应温度75±2℃,滴加单体时间3 h,聚合反应时间6 h,压敏胶性能良好。 In this paper, the solution polymerization method [1], the acrylate and polyurethane 101-B component as raw materials, the synthesis of a glass transition temperature of -48 ℃ solution-based acrylic pressure-sensitive adhesive. The effects of the monomer composition and the ratio of the hydroxyethyl acrylate to the curing agent on the properties of the adhesive were discussed. The results show that when the ratio of hydroxyethyl acrylate to curing agent is 2:1, the reaction temperature is 75 ± 2 ℃, the monomer addition time is 3 h and the polymerization time is 6 h, the pressure-sensitive adhesive has good performance.
