摘要 采用不同升温速率下的非等温DSC研究一种TR1219B耐高温环氧树脂体系的固化反应,分别通过n级反应模型和Malek最大概然机理函数法确定固化反应机理函数,求解固化反应动力学参数,得到固化反应动力学模型。结果表明:通过Kissinger和Crane方法求解动力学参数所得到的n级反应模型与实验值差别较大;采用Malek方法判别机理表明,该固化反应按照自催化反应机理进行,实验得到的DSC曲线与模型计算所得到的曲线吻合良好,所确立的模型在5~20K/min的升温速率下能较好地描述该环氧体系的固化反应过程。

Abstract:The curing processing of TR1219B heat-resistant epoxy system was studied by non-isothermal differential scanning calorimetry (DSC) at different heating rates. The curing kinetic mechanism function and the kinetic parameters were determined using n order reaction model and the most probability mechanism function method given by Malek respectively, and the kinetic model was built. The results indicate that the n order model deviates significantly from experimental data by Kissinger and Crane methods. While the most probability mechanism function method show that the process of curing reactions follows an autocatalytic reaction, and the DSC curves from the autocatalytic model can well agree with that of experiment, the autocatalytic model can well depict the curing reaction process of the studied epoxy resins in the range of 5-20K/min.
