摘　　要：采用氮磷复合物阻燃剂HS-PNA、玻璃纤维、增韧剂、偶联剂对聚对苯二甲酸丁二醇酯进行改性,研究了加工工艺对无卤阻燃PBT性能的影响。实验表明,玻纤含量为30%、阻燃剂含量为17%时,复合材料的阻燃级别达到V0,同时具有高抗冲、高耐热、易于着色、价格低廉的特点,能够满足市场产业化生产的要求。Nitrogen and phosphorus compound flame retardant HS-PNA, glass fiber, toughening agent and coupling agent was used to modify the property of Polyethylene terephthalate （PBT）,the effect of the processing technic on the properties of composite was studied. The results showed that, when the rate of glass fiber was 30%,the rate of flame retardant was 17%,the composites can reach the flame-retardant level of UL94-V0,meanwhile,it also has the property of high impact resistance, high heat resistance, easy coloring, low cost, and can satisfy the demand of market and industrialization production.
