1、梳型紫外光快速固化聚氨酯的制备及涂层性能朱亚丽，董运生，陈丽杰，姚有为，洪阳阳，唐国翌*（清华大学深圳研究生院能源与环境学部，广东深圳518055）摘要：以1,3-丙二醇、甲基丙烯酸缩水甘油酯为主要原料，无水四氯化锡为催化剂，三氟乙酸为助催化剂，合成了一种具有光化学活性的聚醚（PGMA）。此聚醚以碳氧键为主链，以甲基丙烯酸酯基为梳型侧链，端基为羟基。将上述具有光化学活性的聚醚（PMGA）与异佛尔酮二异氰酸酯（IPDI）反应，制得具有光化学活性的聚氨酯〔Poly(PGMA-IPDI)〕。在上述聚氨酯中加入活性稀释剂和光引发剂，制备出一种能够快速光固化的树脂，固
2、化时间可以达到1s，柔韧性达到0.5mm、附着力为最高级0级，同时固化涂层在盐溶液、水溶液、碱溶液中浸泡无脱落，在酸性水溶液中脱落时间也达到36h请多用数据说话，中英文一并修改已改正，中英文相应数据已补充。，涂层具有优异的性能。关键词：紫外光固化；聚醚；阳离子聚合；聚氨酯树脂中图分类号：TQ314文献标识码：ASynthesisoftheComb-likeRapidUV-curedPolyurethaneandItsFilmPropertiesZHUYali,DONGYunsheng,CHENGLijie,YAOYouwei,HONGYangyang,TAN
