摘　　要：用合成的2-(4-氨基苯基)-5-氨基苯并咪唑(APABI)作为环氧树脂固化剂,并与其他固化剂作性能对比。新型固化剂/环氧树脂体系能中温短时(150℃、2h)固化,固化物具有良好的耐热性,初始热分解温度在400℃以上。The laboratory synthesized 2-（4-aminophenyl）-5-aminobenzimidaz-ole （APABI） was used as the curing agent of epoxy adhesive system. Its performance was compared with other curing agents. The new curing agent/epoxy resin system can be cured at medium temperature for short period, such as 150 ℃ for 2 hours. The cured has good heat resistance and an initial decomposition temperature of above 400℃.
