摘要
由环氧树脂固化过程的体积收缩现象来研究加入二氧化硅及二氧化硅表面不同处理的填料的固化反应动力学，结果表明固化过程分为四级、零级与一级反应三个阶段．填料及其不同表面处理对环氧树脂固化反应速度和活化能有影响，但不影响反应历程．与纯树脂体系相比加填料体系体积收缩量较小．
The curing kinetics of epoxy resin to add filler of silica and silica by different surfacetreatment was investigated by an appeerance o f shrink of volume during the curing process'Results silo'ved the witch curing course was divided into four, zeroand one-order stages.Fillerand its different surface treatment were effectiveon reaction velocity and activation of energybat were not effeCtive on reaction course.Compared pure system with filled system,it was foundthat the shrinkage of the volume was less.
