潜伏性热固性树脂体系动力学参数的研究

STUDIES ON KINETIC PARAMETERS OF LATENT THERMOSETTING RESIN SYSTEMS

本文通过对二种潜伏性热固性树脂(环氧树脂)体系动力学参数的分析讨论。结果认为,理想的潜伏性热固性树脂体系的特征是具有较高的反应活化能(Ea)和频率因子(A);或者具有变活化能—既在室温下具有较高的反应活化能。

The kinetic parameters of two kinds of latent thermosetting epoxy resin systems were discussed. The results indicate that an idea latent thermosetting resin system should possess higher reactive activation energy (Ea) and frequency factor (A) , or possess a variable reactive activation energy, that is, the resin system should possess a higher activation energy at room temperature and a lower one at elevated temperature.
