摘要
通过使用丙烯酸羟乙酯(HEA)引进羟基官能团,对甲基丙烯酸缩水甘油酯型(GMA)丙烯酸树脂进行改性,从而提高了GMA型丙烯酸树脂的柔韧性和抗冲击性,改善了产品的流平性能和附着力;探讨了不同的溶剂和引发剂、引发剂的用量、反应时间和温度对产品性能的影响;制备得到的新型丙烯酸树脂的环氧当量为547 g/mol,数均分子量为15 000 g/mol左右,软化点为108.6℃。
Hydroxyl functional groups were introduced into glycidyl methacylate(GMA)acrylic resin by using HEA to improve the flexibility and impact resistance of GMA acrylic resin and improve the leveling property and adhesion of the product.The effects of different solvents and initiators,initiator dosage,reaction time,and temperature on the properties of the product are discussed.The epoxy equivalent of the new acrylic resin prepared was 547 g/mol,the average molecular weight was about 15000 g/mol,and the softening point was 108.6℃.
