摘要
采用含浸压缩成型工艺制备了过氧化苯甲酸-1,1-二甲基乙基酯(TBPB)/环氧大豆油丙烯酸酯(AESO)复合材料,对其固化过程及结构进行了考察。结果表明,基于Kissinger法及Starink法计算得到TBPB/AESO复合材料的反应活化能为78.803 kJ/mo;基于Malek法选择Sesthk-Berggren作为固化模型,拟合计算得到的固化动力学方程能较好地与实验数据吻合;优化的TBPB/AESO固化工艺为先缓慢升温至407 K,再快速升温至424 K恒温固化,最后缓慢升温至489 K并保持一定时间。
tert-butyl peroxy benzoate(TBPB)/acrylated epoxy soybean oil composite(AESO)composite was prepared by immersion compression for-ming technology,and its curing process and structure were investigated.The results showed that the reaction activation energy of TBPB/AESO composite calculated based on Kissinger method and Starink method was 78.803 kJ/mol.Sesthk-Berggren was selected as the curing model,and the calculated curing kinetics equation based on the Malek method fitted well with the experimental data.The optimized curing process of TBPB/AESO involved increasing slowly the temperature to 407 K,then increasing rapidly the temperature to 424 K for constant temperature curing,and finally increasing slowly the temperature to 489 K for a certain period of time.
