摘　　要：合成并表征了端氨基苯基聚丙二醇(APPPG),并用它作为固化剂与环氧树脂组成了综合力学性能好的胶粘剂。研究了合成APPPG的工艺条件、以及APPPG的用量和试件表面处理工艺对胶粘剂粘结性能的影响。结果表明:当APPPG与E-44环氧树脂的质量比约为1时,组成的胶粘剂有最佳的综合力学性能;用0号纱布打磨试件表面制成的试样,其剥离强度最高。Based on the synthesis and characterization of α,ω-biaminophenyl-terminated poly(propylene glycol)(APPPG),a high performance adhesive containing APPPG and epoxy resin was available. Effects of reaction time and temperature on the yield of APPPG,as well as effects of the weight ratio of APPPG to E-44 epoxy resin and surface treatment of the substrate on the adhesive's mechnica) properties were studied. The results showed that the optimal comprehensive properties of the adhesive occurred when the weight ratio of APPPG to E-44 epoxy resin was about 1.0. Using sand paper with NO:0 to pretreat the substrate would obtain the biggest peeling strength of the sample.
