【摘要】 聚对苯二甲酸乙二醇酯（PET）是一种应用广泛的热塑性塑料。但其易燃烧,而且燃烧时伴随大量熔滴和烟,严重影向了聚酯的使用安全。因此阻燃改性一直是聚酯研究的重点和热点。本文将反应型含磷阻燃剂2-羧乙基苯基次膦酸（CEPPA）和纳米ZnCO₃同时引入到聚酯体系中,制备了一种新型、抗熔滴的高效阻燃共聚酯纳米复合材料。并对其燃烧性能和阻燃性能进行了研究。更多还原

【Abstract】 Poly（ethylene terephthalate）（PET） resins are semicrystalline thermoplastic resins widely used in many industrial applications.The flammability,the poor anti-dripping property of PET and ease of giving off thick smoke during burning restrict the range of their applications.Therefore, many studies have been focused on the improvement of flame retardancy of PET. In this paper,a novel flame retardant PET was synthesized based on reactive phosphorus-containing flame retardant（CEPPA） and nano-ZnCO₃.The flammability and fire resistance of the copolyester and its nanocomposite were also investigated.更多还原
