摘要
以环氧树脂为壁材,聚磷酸铵(APP)为核,通过原位聚合的方式制备出微胶囊包覆聚磷酸铵(EAPP)。同时复配纳米碳材料(碳纳米管和石墨片),制备环氧树脂复合材料,研究了复合材料的阻燃和导电等性能。结果表明:经微胶囊包覆后的APP在环氧树脂基体中的分散性得到改善,复合材料的阻燃性能也得到提高。当100g环氧树脂添加10g EAPP及3g碳纳米材料时,复合材料的氧指数提高至28.6%,电导率提高至6.61×10-3S/cm,达到导电级别。
Microencapsulated ammonium polyphosphate(EAPP)was prepared by using of epoxy resin as wall material and ammonium polyphosphate as core material based on in situ polymerization.Besides,carbon nanoparticles(carbon nanotubes and graphite sheet)were incorporated to prepare EP composites,and the flame retardant and electrically conductive properties were studied.The results showed that the microencapsulated APP improved the dispersibility in the EP matrix as well as the flame retardancy of the composites.With the presence of 10 g EAPP and 3 g carbon nanomaterials,the LOI of 100 g EP composites increased to 28.6%,and the electrical conductivity was also increased to 6.61×10-3 S/cm,reaching the conductive level.
