摘要
用 PE DSC-7仪器测定了 N,N,N′,N′—四烯丙基二苯甲烷二胺改性双马来酰亚胺树脂的比热容,并借助DSC-7动力学软件得到该树脂的固化反应级数n=1.39±0.10、反应活化能E_a=138±7.77kJ/mol和表观频率因子InZ=28.6±1.921/sec;还预测了树脂的固化反应程度(d),固化反应温度(T)和固化反应时间 (t)三者间相互关系,并计算了凝胶化温度(Tgel)、固化温度(Tcure)和后处理温度(Ttreat)。
The specific heat, curing reaction order, activation energy of reaction, and apparent frequency factor of the bismaleimide resin modified with N, N, N', N' - tetraallyl diphenyl methane diamine. Were examined, the reactionship between the cure degree of cure reaction, cure temperature and cure time was predicated, and the gelation temperature, cure temperature and postreatment temperature were calculated.
