摘要
分别采用Kissinger模型和Flnn–Wall–Ozawa(FWO)模型研究了E–51型环氧树脂/胺基酰亚胺潜伏性固化体系的非等温固化动力学,得到了该体系在这2种模型下的固化反应活化能。分析了不同动力学模型对该体系固化反应动力学研究的影响。结果表明,由2种模型得到的固化动力学参数基本相近。E–51/胺基酰亚胺体系的固化反应具有变活化能特征,固化反应起始阶段的活化能较高,约为103-112 kJ/mol;当固化度为0.9时,活化能约为63-82 kJ/mol。
The non-isothermal curing kinetics of E-51 epoxy resin/aminimide latent curing system was investigated by using Kissinger model and Flnn-Wall-Ozawa （FWO） model separately and the curing reaction activation energy of the system under such two models was obtained. The influence of different kinetics models on the curing reaction kinetics of such system was analyzed. The results show that the curing kinetic parameters obtained from the two models are basically closed. The curing reaction of E-51/aminimide system possesses variable activation energy characteristics. The activation When the curing degree is 0.9, energy during the initial stage of the curing reaction is higher, it is 103-112 kJ/mol the activation energy is 63-82 kJ/mol.
