叔丁基酚缩水甘油醚丙烯酸酯的合成及其在紫外光固化涂料中的应用

以叔丁基酚缩水甘油醚和丙烯酸为主要原料,三苯基膦为催化剂,对羟基苯甲醚为阻聚剂,合成一种新型的活性稀释剂——叔丁基酚缩水甘油醚丙烯酸酯。通过对反应时间、反应温度、反应转化率、产物色泽和体系黏度等考察,得出较佳反应条件：温度为100～110℃,三苯基膦的质量分数为0.7%～0.9%,对羟基苯甲醚质量分数为0.2%～0.3%。将合成的活性稀释剂和光引发剂加入到双酚A型环氧丙烯酸酯树脂中配成紫外光固化涂料,对涂膜进行了拉伸、硬度、柔韧性等测试。结果表明：此预聚物配成的涂料具有较好的力学和热性能。

Synthesis of 4-Tert-butyl Phenol Glycidyl Ether Acrylate and Its Application in UV-curable Coating

A novel reactive diluent was synthesized with 4-tert-butyl phenol glycidyl ether and acrylic acid as the main materials,triphenyl phosphine as the catalyst,and p-hydroxyanisole as the inhibitor.By investigating the reaction conversion,the color of product,and the viscosity of the system,the experiment results showed that the optimum conditions were as followings：the reaction temperature was 100-110 ℃,triphenyl phosphine mass fraction was 0.7%-0.9%,p-hydroxyanisole mass fraction was 0.2%-0.3%.The UV-curing coating was prepared with synthesized reactive diluent and the photoinitiator and bisphenol-A epoxy resin.The tensile,hardness and flexibility test were performed for the UV-cured films.The results showed that the coating had good mechanical and thermal properties.
