-
摘要: 应用动态粘弹谱仪的环形剪切方法,在恒定的温度条件下,对环氧树脂的固化潜伏期、凝胶化时间和固化过程进行了分析测定.根据计算机处理的数据绘出样品粘度和剪切模量随时间变化的关系谱图,为研究环氧树脂的固化全过程提供了一种有效的表征方法.Abstract: The method to determine the course of the epoxy resin curing at constant temperature with a dynamic viscoanalyser is described. According to the tested data,the curves of the viscosity and the shear modulus with the change of time were ploted. This is a new method for analysis of the curing course of epoxy resin.
