摘　　要：以甲基六氢邻苯二甲酸酐(MeHHPA)为固化剂,N,N二甲基苄胺为固化促进剂,在一定的固化条件下,对双酚F环硫环氧树脂进行固化实验,探讨了固化机理。并对双酚F环硫环氧树脂固化物的吸水性、拉伸强度、剥离强度和玻璃化温度进行分析测试,结果表明,与双酚F环氧树脂相比,相应的双酚F环硫环氧树脂具有更高的拉伸强度、剥离强度和玻璃化温度以及较低的吸水性。Using MeHHPA as the hardener and N,N-dimethyl benzylamine as the catalyst,the curing behavior and reaction mechanism of bisphenyl F epoxy-episulfide resin system were studied under a cured condition. Glass transition temperature of cured compounds were investigated using DSC.The effect of episulfide value of bisphenyl F epoxy-episulfide resins on the properties,such as water absorption,glass transition temperature,tensile strengh and peel strengh was investigated,and the results showed that bisphenyl F epoxy-episulfide resin system has some significant advantages over common epoxy resins:lower water absorption,higher glass transition temperature,higher tensile strengh and more rapid low temperature curing.
