| 摘 要： | 以1,2-环氧-9-癸烯和双侧氢封端的聚二甲基硅氧烷为反应物,在卡斯特催化剂〔铂(0)-1,3-二乙烯基-1,1,3,3-四甲基二硅氧烷〕的催化下发生硅氢加成反应,成功制备了双端环氧基聚硅氧烷预聚物,并使用阳离子型光引发剂对其进行紫外光固化,制得紫外光固化环氧聚硅氧烷树脂。对合成双端环氧基聚硅氧烷预聚物的反应条件进行优化。利用FTIR和1HNMR对所合成预聚物的结构进行了表征,采用热失重分析、差示扫描量热法、接触角、耐碱性、耐醇性、凝胶率、邵氏A硬度和断裂面微观形貌对固化膜的性能和形貌进行了测试与表征。结果表明:在反应温度为75℃、催化剂有效成分添加量为0.009‰(以双端含氢聚硅氧烷和1,2-环氧-9-癸烯的质量和为基准,下同)条件下,8 h时反应程度达93.95%;当使用光引发剂BL9380用量为3%(以预聚体质量为基准,下同)、固化时间为20s时,制得的树脂表面自由能为18.4～18.8mJ/m2,耐碱性、耐醇性良好,凝胶率为93.9%,邵氏A硬度为37,空气气氛下两个最大分解速率的对应温度分别为437.6和511.3℃,780℃下残炭率为13.9%,固化膜的综合性能较好。
