为改善传统石油树脂改性方法能耗高、效率低等缺陷,本文应用点击化学,在常温下,以甲苯为溶剂,以Darocur1173为光引发剂,在UV-LED灯辐照下,通过3-巯基丙酸与DCPD石油树脂发生巯基-烯加成反应,制备的产物命名为DCPD-COOH.以三苯基膦为催化剂,用甲基丙烯酸缩水甘油酯(GMA)与DCPD-COOH反应,制备了可光固化的丙烯酸酯石油树脂,命名为DCPD-A.固化漆膜的设计配方:DCPD-A(50份)、活性稀释剂甲基丙烯酸羟乙酯(HEMA,50份),光引发剂Darocur1173(5份).在该配方下制得的固化漆膜其附着力达到0级,铅笔硬度为2H.制备的DCPD-A与极性溶剂或者极性树脂的相容性较好,可应用于光固化涂料和光固化油墨等领域.
