摘　　要：以端羟基聚丁二烯、3-异氰酸酯基亚甲基-3,5,5-三甲基环己基异氰酸酯、丙烯酸羟乙酯为原料合成聚氨酯二丙烯酸酯预聚物。以该预聚物和四氢呋喃丙烯酸酯、N,N-二甲基丙烯酰胺、γ-缩水甘油醚基丙基三甲氧基硅烷、1-羟基环己基苯基甲酮、2,4,6-三甲基苯甲酰基-二苯基氧化膦、纳米气相二氧化硅为原料配制UV胶,具有较佳的力学性能、粘接强度、耐湿热和耐冷热冲击性能,综合性能可满足L ED背光源透镜粘接总体要求。The polyurethane di-acrylate was synthesized using hydroxyl-terminated polybutadiene-diol, IPDI and hydroxyethyl acrylate. Then the UV curable adhesive was prepared from the polyurethane di-acrylate, THFA, N,N- DMA, 2,3-epoxypropoxy propyltrimethoxysilicone, 1-hydroxycyclohexyl phenyl ketone, 2,4,6-trimethyl benzoyl diphenyl phosphine oxide and fumed silica as the raw materials. The experiment results indicated that the UV curable adhesive had better mechanical properties, bonding performance and resistances to heat-humidity and temperature shock, and its comprehensive properties was able to meet the LED lightbar lens＇ bonding requirements.
