摘　　要：以自制的聚醚链段为柔性链段、苯脂肪氨基为刚性链段的新型端脂肪氨基聚醚(APPEG)为固化剂制备了可室温固化的环氧树脂(E-44)胶粘剂,研究了环氧树脂增韧体系的微观形貌和力学性能。结果表明:固化剂对环氧树脂具有明显的增强、增韧效果,当APPEG与E-44的质量比为0.67∶1时,胶粘剂表现出最佳的综合力学性能;胶粘剂的玻璃化转变温度Tg为22℃,具有较好的耐温性和阻尼性能。A novel room temperature curing adhesive was prepared with polyether as the flexible segment and benzene aliphatic amino as rigid segment. The micromorphology and mechanical properties of α,ω-biaminophenyl terminated poly（ethylene glycol） （APPEG）/bisphenol A has been researched. The result shows that the adhesive has both high toughness and high modulus. The optimal comprehensive properties of the adhesive occurred when the weight ratio of APPEG to E-44 was about 0.67. The glass transition temperature （Tg） is about 22 ℃ and the adhesive has a good heat resistance and damping performance.
