摘　　要：采用热重分析(TGA)研究了三元乙丙橡胶(EPDM)、乙烯-醋酸乙烯共聚物(EVA)和乙丙橡胶(EPR)三种橡胶材料的热分解特性,并计算出三种材料的热分解活化能,然后参照ASTM E1877中的方法建立了三种材料的热寿命方程。TGA was used to study the thermal decomposition characteristics of EPDM, EVA and EPR insulation ma-terials. The activity energies were calculated and the thermal aging life equations were obtained by the method de-scribed in ASTM E1877.

关 键 词：热重分析 绝缘材料 活化能
