摘要
以多官能丙烯酸酯为骨架,接入含氢硅氧烷分子链,并引入有机胺基团合成了一种性能优良的有机硅改性光敏促进剂。介绍了其基本配方,并对两步反应对光敏促进剂性能的影响、反应温度及反应时间对两步反应的影响等进行了研究。该促进剂能显著提高涂膜的光固化速率,改善涂膜的消泡和流平性能。
A kind of modified photosensitive accelerant with organosilane having good performances was synthesized with multi-functional acrylic ester as main chain, with hydrogen siloxane as branched-chain, and by using organic amine group. The basic formula was introduced. The effect of the order of two reaction steps in the synthesis on performances of the accelerant, and the effect of temperature and time on the two steps of reactions, etc., were studied. The accelerant can improve the photo-curing rate, antifoaming performance and leveling performance of the coatings.
