摘　　要：采用熔融共混法制备一种阻燃聚对苯二甲酸乙二醇酯(PET)混杂复合材料,利用扫描电子显微镜及采用差示扫描量热法和力学性能测试等方法,研究了蒙脱土(MTT)、高岭土和埃洛石炭纳米管(HNTs)三种无机粒子对PET的结晶性能、力学性能、耐热性和流动性及断面形貌的影响.结果表明,添加2%无机粒子的PET混杂复合材料具有较佳的综合性能.在添加2%无机粒子的PET混杂复合材料的基础上,再添加30%的玻纤和11%的聚溴化苯乙烯/三氧化二锑复合阻燃剂,所制备出的增强型阻燃级PET混杂复合材料具有优良的性能.A novel flame retardant PET hybrid composite has been prepared by melting blending. The effects of montmorillonite（MMT）, kaolinite and halloysite nano-carbon nanotubes（HNTs） upon crystallization, mechanical properties, heat resistance, flowability and fracture surface morphology of PET were investigated by DSC, SEM and mechanical tests,etc. The results showed that PET hybrid composite had the optimal comprehensive properties when adding 2 wt % inorganic particles. Reinforced and flame retardant PET hybrid composites With good comprehensive properties were developed when 30% glass fiber and 11% flame retardant consisting of PBS and Sb2O3 was applied to the composites.
