摘要: 用示差扫描量热仪(DSC)对含联苯结构环氧树脂(TMBP)/4,4′-二氨基二苯砜(DDS)固化体系的固化反应过程进行了分析,并用Kissinger和Ozawa方法分别求得体系固化反应的表观活化能ΔE为69.7和74.2kJ/mol,根据Crane理论计算得到该体系的固化反应级数n=0.89及在不同升温速率下的频率因子A,确定了使用DDS作为固化剂的固化反应条件.

关键词: 联苯, 环氧树脂, 固化反应动力学

Abstract: The reaction process of the curing system(TMBP/DDS) was studied by DSC and carefully analyzed. Based on the Kissinger method and Ozawa method, the apparent activation energy(ΔE) was got 69.7 and 74.2 kJ/mol respectively. The reaction order(n=0.89) and frequency factor A in various temperature were calculated according to Crane theory. The curing reaction condition was made by using DDS as the curing regent.

Key words: Biphenyl, Epoxy resin, Curing reaction kinetic
