摘要
用差示扫描量热仪(DSC)对间苯二甲酸二烯丙酯(DA IP)改性酚醛环氧树脂(F-51)固化体系的固化反应过程进行了分析。用K issinger方法求得体系固化反应的表观活化能ΔE=49.9kJ/m o l,根据C rane理论计算得到该体系的固化反应级数n=0.87。为初步确定甲基四氢苯酐(M eTHPA)和顺丁烯二酸酐(MA)两种酸酐作为固化剂的固化反应条件提供了一定的理论依据。
: The curing reaction process of system (DAIP/EP) was studied by DSC. Based on Kissinger method and Crane theory, the apparent activation energy (AE) is 49.9 kJ/mol, and reaction order (n) is 0.87 respectively. The results provide an elementary theory for further studying the curing reactions where the MeTHPA and MA used as solidifying reagents.
