酚醛胺固化环氧树脂热降解动力学研究

Thermal Decomposition Kinetic of Epoxy Resin Cured with Mannich Amide

利用市售酚醛胺PPA固化剂固化环氧树脂E-44,对固化产物热稳定性进行研究,用Flynn-Wall-Ozawa法建立了固化产物热降解动力学模型,得出热解活化能E227.51 kJ/mol,lgA14.34(A2.19×1 014 s-1)。

The epoxy resin was cured with the reacting from mannich amide.To study the decomposition kinetic for epoxy resin cured with mannich amide,an activated energy of 227.51 kJ /mol,a pre-exponential factor of 2.19×1 014 s^-1.
