摘要
用萃取法研究了4-乙烯基-4’-甲氧基二苯甲酮(4-VMBP)和二苯甲酮(BP)在固化膜中的残留量;用实时红外法研究了4-VMBP的光聚合动力学,考察了胺浓度、引发剂浓度、灯距、氧阻、固化方式对氨基丙烯酸酯6116固化时间的影响。结果表明4,-VCBP固化残留量比BP小一个数量级;4-VMBP和三乙醇胺(TEOA)匹配性最好;固化体系中4-VMBP和TEOA质量分数均为4%时较为合适;隔绝空气条件下,固化时间缩短;灯距从10 cm调到20 cm,固化时间延长2倍多;间歇固化时间是连续固化的2倍多。
By extraction,the residues of 4-vinyl-4＇-methoxy benzophenone（4-VMBP） and benzophenone（BP） in the cured film were analyzed.By real-time infrared spectrum,the photopolymerization kinetics of 4-VMBP were studied,and the effects of amine concentration,initiator concentration,light distance,oxygen resistance and curing methods on the curing time of amino acid ester 6116 were researched.The results showed that the residues of 4-VCBP were an order of magnitude smaller than that of BP,4-VMBP and TEOA matched well,the favorable concentration of 4-VMBP and TEOA were both 4%,the curing time of ester was shortened without air and was double longer when light distance changed from 10 cm to 20 cm.The intermittent curing time was twice more than the continuous curing time.
