| 摘 要： | 采用可见光引发自由基-阳离子混杂光固化体系,固化环氧/丙烯酸酯制备的复合树脂,重点研究了自由基光引发剂樟脑醌和阳离子光引发剂二苯基碘鎓六氟磷酸盐质量比对固化时间、固化深度、线尺寸变化率及树脂性能的影响。结果表明:在可见光的照射下,当樟脑醌在混合引发剂中的质量分数为0.75时,固化时间为6s,光固化深度为7.86mm,线尺寸变化率为0.2%,固化复合树脂的综合性能优良;很好地证明了自由基-阳离子混杂光固化体系结合了自由基聚合和阳离子聚合的优点,表现出较好的协同效应。

| Abstract: | Composite resin of Epoxy-Acrylic was prepared by free radical-cationic hybrid curing systemin visible light-cured,and the influence of the proportion of free radical(CQ) and cationic initiator(DPI·PF6) on curing time,curing depth,linear dimension change and properties of composition were mainly studied.The results show: when the mass fraction of CQ is 0.75,the curing time is 6s,the curing depth is 7.86mm,the linear dimension change is 0.2%,and the synthetic performance of the composite resin is excellent.This result demonstrated that free radical-cationic hybrid curing system combined the advantages of radical and cationic polymerization,and exhibited a better synergy effect. |
