STUDY OF THE MODERATE TEMPERATURE CURING EPOXY RESIN——Ⅱ.Investigation on the apparent kinetics of the curing reaction

摘要: 按Ellerstein的方法,用差示扫描量热分析仪对环氧6l8^#树脂/DDS/促进剂AB体系的热固化反应进行了研究.借助计算机跟踪求积,仅从一条实验曲线就较准确地求出了固化反应的表观动力学方程.井对树脂体系的反应特性、贮存特性进行了预测.

Abstract: Using Differential Scanning Calorimeteter according to Ellerstein's method,the thermal curing reaction of the Epoxy Resin 618^#/DDS/Accelerator AB system is studied. With the help of computer,the key parameters and the apparent kinetics equation of the curing reaction characteristic and the pot life of the resin are predicted.
