摘要

以双酚A型环氧树脂为主体成分构成紫外阳离子光固化体系，用常规的最低光固化速度测试方法和实时傅立叶变换红外光谱法研究了各种条件对体系光固化速度的影响。结果表明，光引发剂的种类和浓度可以有效地改变光固化速度，环氧稀释剂会大幅度降低光固化速度，而羟基化合物的加入只是轻微降低光固化速度。在三元体系中，其光固化速度并不是几种作用的简单叠加，而是更加类似于羟基化合物的性质。使得通过调节合适的组分构成和配合，能够获得具有合适光固化速度的紫外阳离子光固化配方，从而会大大扩展其应用的技术领域。

Abstract

Cationic UV curing of bis-phenol A epoxy resin was studied. Effects of the component combinations on photocuring kinetics were investigated with the lowest photocuring rate method and Real-Time FTIR. The results demonstrated that epoxide dilute decreased the photocuring rate obviously and hydroxyl compound (HC) showed slight influence. But in a combination system, the HC exhibited unique dominative function on photocuring rate.
