Application of novel compound bis-(4-aminophenyl)phenylphosphonate in epoxy resin system

The invention discloses application of a compound bis-(4-aminophenyl)phenylphosphonate serving as a novel flame retardant curing agent in an epoxy resin system. The application method comprises the steps that bis-(4-aminophenyl)phenylphosphonate serves as the curing agent and is added into the epoxy resin system to be evenly mixed, and a cured epoxy resin system is obtained after forming, curing and post-curing. The adopted novel curing agent can be used for curing and flame retardance of epoxy resin, the curing effect and the compatibility are good, since no halogen is included, few smoke andlow toxicity are achieved, and the requirements for novel environment-friendly curing agents are met. 本发明公开了化合物二-（4-胺基苯基）苯基膦酸酯作为新型阻燃固化剂在环氧树脂体系的应用，应用方法为：将二-（4-胺基苯基）苯基膦酸酯作为固化剂加入到环氧树脂体系中混合均匀，并经成型、固化、后固化后，得到环氧树脂体系固化物。本发明所采用的新型固化剂既可固化环氧树脂又能用于环氧树脂阻燃，并且固化效果、相容性均较好，由于不含卤素因此低烟低毒，符合新型绿色环保型固化剂的要求。
