摘要：利用红外光谱跟踪体系光固化反应过程中的双键转化，比较了不同光引发剂的引发活性，探讨了光固化反应的各种影响因素和反应规律。发现光引发剂ａ，ａ－二甲氧基－ａ－苯基苯乙酮（ＩＲ６５１）和ａ－羟基－ａ，ａ－亚戊基苯乙酮（ＩＲ１８４）的活性显著大于安息香乙醚（ＢＥ）；升高温度、增大入射光强和在氮气气氛中反应，可有效提高光固化反应速度和涂漠的最终转化率。
The photocuring processes of acrylic acid and acrylate were monitored by mea-suring the variation in double bond content with IR spectrometry.The initiating efficiency ofdifferent photomitiators and various factors affecting the photocuring reaction were examined.It was obviously found that the efficiency of a, a-dimethoxy-a-phenylacetophenone(IR651)and a-hydroxy-a,a-pentamethylene-acetophenone (IR 184) is higher than that ofbenzoin ethyl ether(BE),and that the speed of the photocuring reaction and the final conversion of coatings can be increased with raising temperature and incident light intensity as wellas using inert(N_2)atomosphere.
