摘要

摘要: 对二苯基碘鎓六氟磷酸盐引发的环氧树脂电子束(EB)辐射固化反应动力学进行了研究,应用环氧树脂乙腈溶液推导出引发剂辐射分解速率常数和引发、增长反应速率.动力学研究结果表明,二苯基碘鎓六氟磷酸盐引发剂经电子束辐射分解产生质子酸的过程是二级反应,在辐射反应过程中,环氧树脂体系的引发速率和增长速率分别迅速达到最大值后逐渐减小.

Abstract: The kinetic studies on electron beam (EB) curing of epoxy resins were made. The experimental results manifested that a second-order reaction is involved during the production of protonic acid deriving from radiation decomposition of diaryliodonium salts initiator and the decomposition kinetic constant is obtained. The rate of initiation and propagation for epoxy resin in acetonitrile solution has a rapid increase up to a maximum value, and then decrease.
