Abstract:

The curing process of epoxy monomer (3EPZ) containing heteronaphthalene biphenyl structure with polyether amine (ED-2003) was investigated by differential scanning calorimetry (DSC). The activation energy and related kinetic parameters of the system at different conversion rates were obtained using the Starink model and the autocatalytic model, and the kinetic equations were established. The correlation coefficients between the experimental results and the model calculations were greater than 99%, indicating that the autocatalytic kinetic model developed can better describe the curing process of the system.

Key words: epoxy resin, curing kinetics, autocatalytic model

摘要:

采用差示扫描量热法(DSC)对含杂萘联苯结构环氧单体(3EPZ)与聚醚胺(ED-2003)的固化过程进行研究。采用Starink模型及自催化模型获得了不同转化率下体系的活化能及相关动力学参数,并建立了动力学方程。实验结果曲线与模型计算结果曲线的相关系数大于99%,表明所建立的自催化动力学模型能够较好地描述体系的固化过程。
