摘要: 采用差示扫描量热仪研究了不同牌号环氧树脂对双马来酰亚胺/氰酸酯(BMI/CE)树脂体系在不同升温速率下的固化反应。在保持BMI/CE质量比为1/2的前提下,加入同等质量不同牌号环氧树脂,运用Kissinger法、Ozawa法和Crane法求得不同体系的活化能、反应级数等动力学参数。结果表明,用环氧树脂(AG-80)改性的BMI/CE树脂体系的活化能的平均值为81.55kJ/mol,反应级数为0.93;环氧树脂(TDE-85)改性的BMI/CE树脂体系的活化能的平均值为69.25kJ/mol,反应级数为0.92;环氧树脂(TDE-85)改性的BMI/CE树脂体系更有利于固化工艺的实现。

Abstract: The cure kinetics of epoxy resin (AG-80 and TDE-85) modified bismaleimide/cyanate (BMI/CE) system was investigated at different heating rate, using non-isothermal differential scanning calorimetry (DSC). The curing kinetics parameters of the system were obtained by Kissinger, Ozawa equation, and Crane's theory. For epoxy resin (AG-80) modified system, the average activation energy was 81.55kJ/mol, and the reaction order was 0.93. For epoxy resin (TDE-85) modified system, the average activation energy was 69.25kJ/mol, the reaction order was 0.92.Compared to epoxy resin (AG-80) modified system, the results indicated that the addition of epoxy resin (TDE-85) could lower the activation energy of the modified system and the curing reaction could occur at a relative low temperature.
