摘　　要：首先探讨了磷酸酯(PX)及纳米氧化镁(MG)对聚对苯二甲酸丁二醇酯(PBT)阻燃和力学性能的影响。然后固定磷酸酯阻燃剂用量,考察了纳米氧化镁的添加量对PBT/PX复合体系的阻燃性能和力学性能的影响。实验结果表明,在磷酸酯阻燃剂的质量分数为15%,纳米氧化镁为10%时,PBT复合材料在保持一定的力学性能的基础上氧指数从20.3%提高到28.8%,达到UL94 V-0级,并表现出良好的消烟效果,表明该PBT复合体系具有优良的阻燃性能和力学性能。Effects of phosphate ester and Nano-MgO on flame retardanee and mechanical properties of PBT system were investigated experimentally. Nano-MgO flame retardant amount was fixed and then the addition of MgO on the flame retardanee and mechanical properties of PBT/PX composite was researched, the results showed that by using 15 wt% phosphate ester and 10 wt% Nano-MgO, LOI of PBT increased from 20. 3% to 28.8% achieving UL-94 V-0 level with keeping mechanical properties and conducted well smoke suppressants. PBT composite had excellent flame retardanee and mechanical property.
