计算机辅助DSC研究四官能环氧树脂固化反应动力学

A STUDY OF COMPUTER AIDED DSC FOR THE CURE REACTION KINETICS OF TETRAFUNCTIONAL EPOXY RESIN

摘要: 本文应用等温DSC研究了四官能环氧AG-80/DDS体系的固化反应动力学,采用计算机处理数据,用分段抛物插值法模拟DSC曲线,用回归分析法求出了反应级数、反应速率常数和反应活化能,建立了反应程度与温度和时间的定量关系,为模拟反应过程,制定合理的固化工艺参数提供了依据。

Abstract: The cure reaction kinetics of tetraglycidyl 4, 4'-diaminodiphenl methane (AG-80)-Diaminodiphenyl sulfone (DDS) epoxy resin system was investigated by isothermal DSC.The DSC data were processed with computer and the DSC curve was simulated by sectional parabola interpolation method.
