摘要
利用等温DSC法对E-51环氧树脂/2-甲基咪唑(2-MI)体系的固化动力学进行了研究,拟合得到n级固化模型、自催化模型及Kamal复合模型方程中的各个参数值,以确定固化模型。研究表明:E-51/2-MI体系的固化过程分为2个阶段,即诱发阶段和加成反应,其固化反应兼具n级固化与自催化的特征,符合Kamal复合模型。
The curing kinetics of E-51epoxy resin/2-methyl imidazole（2-MI）system was studied using isothermal DSC.The corresponding parameter values of the n-order curing model,autocatalytic model and Kamal model were obtained by fitting to determine the curing model.The result showed that the curing process of E-51/2-MI included two stages ： induced stage and addition reaction stage.The curing reaction had both n-order curing and autocatalytic model characteristics and was in line with the Kamal composite model.
