摘　　要：通过以聚苯氧基磷酸联苯二酚酯(PBPP)阻燃剂和聚苯氧基磷酸联苯二酚酯(PBPP)/聚磷酸铵(APP)复合阻燃剂分别混合石墨烯对环氧树脂(EP)进行阻燃改性对比研究。通过氧指数(LOI)、垂直燃烧(UL-94)、力学性能、热失重(TGA)等方法研究单一阻燃剂和复合阻燃剂对环氧树脂(EP)阻燃性能的影响。结果表明,PBPP/APP-EP体系比PBPP-EP体系的效果更好,复合阻燃剂效果比单一阻燃剂PBPP阻燃效果好。In this paper,the flame retardant modification of epoxy resin(EP)by graphene blends of polyphenoxydiphenyl phosphate(PBPP)flame retardant and polyphenoxydiphenyl phosphate(PBPP)/ammonium polyphosphate(APP)flame retardant was studied.The effects of both flame retardants on the flame retardant properties of epoxy resin(EP)were studied by means of oxygen index(LOI),vertical combustion(UL-94),thermogravimetry analysis(TGA),and mechanical properties test.The results showed that at the same loading,the effect of PBPP/APP-EP system was better than that of PBPP-EP system.
