摘要:
对不同种类光引发剂与丙烯酸酯型光固化树脂(APR)的紫外光固化反应进行了研究.通过凝胶率的测定研究光固化速度的影响因素,对各种固化体系进行了漆膜性能测试并利用红外光谱分析了丙烯酸酯型环氧预聚物(AEP)、丙烯酸酯型光固化树脂、丙烯酸酯型光固化树脂/ Omnicat432BPO体系热固化前后的涂膜结构.结果表明:光固化速度与光引发剂种类、丙烯酸含量及光敏剂有关;漆膜性能测试表明阳离子-BPO混杂光引发体系更有利于改善涂膜的硬度;阳离子安息香丁醚混杂光引发体系不利于涂膜性能的改善.
Abstract:
The UVcuring reaction of acrylated photocurable resin (APR) and diffirent photoinitiators were discussed. The influence factors on photocuring rate was investigated with gel percent of the system. Moreover, Coating structure of acrylated epoxy prepolymer (AEP), APR with the same content of acrylic acid, before and after the thermal curing of the APR/Omnicat432BPO system were characterized by FTIR spectrum. The results showed that the photocuring rate was related to the photoinitiator’s type, the acrylic acid content and the photosensitizer. The film performance tests showed that the cationBPO hybrid photoinitiator system was more conducive to improving the coating hardness; the cationbenzoin nbutyl ether photoinitiator hybrid system wasn’t conducive to the improvement of coating performance.
