摘　　要：以活性增韧剂CYH-277对环氧树脂进行稀释、增韧,制备了无溶剂建筑结构胶粘剂。对活性增韧剂的结构进行了表征,考查了CYH-277对环氧树脂黏度的影响,研究了固化物的热性能,并用扫描电子显微镜(SEM)表征其形态结构,测试了制备的无溶剂建筑结构胶粘剂的力学性能。结果表明,CYH-277能够有效降低环氧树脂的黏度,调整施工性能,改善环氧树脂胶粘剂的综合性能。Solvent-free strtucture adhesives were prepared by diluting and toughening of epoxy resin with CYH-277 as the reactive toughening agent. Strtucture of CYH-277 was characterized by FT-TR. Effect of CYH-277 on epoxy resin viscosity was investigated, the thermal properties of the cured was studied and its morphological structure was characterized by SEM. Mechanical properties of adhesives were tested. Experimental results showed that CYH-277 can efficiently decrease the epoxy resin viscosity, adjust the workability and improve the comprehensive performance of the epoxy resin adhesive.
