摘要

采用非等温DSC法对低黏度体系CY184/IPDA环氧树脂体系及对CY184/ES184/IPDA环氧/环硫树脂体系的固化反应动力学进行了研究。用高级等转化率Vyazovkin积分法求取活化能Ea

通过Málek法确定了固化反应机理函数和动力学参数

得到固化反应动力学方程。结果表明:CY184/IPDA环氧树脂体系的平均活化能为47.04 kJ·mol-1;CY184/ES184/IPDA环氧/环硫树脂体系的活化能为48.97 kJ·mol-1。两种体系的模型拟合曲线与实验得到的DSC曲线吻合得较好

均符合esták-Berggren(m

n)模型。

Abstract

The curing kinetics of a low viscosity epoxy resin system CY184/IPDA and an epoxy-episulfide resin system CY184/ES184/IPDA were studied by non-isothermal DSC.An advanced isoconversional method proposed by Vyazovkin was used to solve the activation energy of these resin systems.Based on the Málek method

curing mechanism functions and reaction kinetic parameters were obtained and the curing kinetic equations of these systems were determined.Average activation energy values for CY184/IPDA and CY184/ES184/IPDA epoxy/episulfide resin system were 47.04 kJ·mol-1 and 48.97 kJ·mol-1 respectively.The calculated curves fitted well with experimental DSC curves of these systems which could be described by Šesták-Berggren(m

n)model.
