摘　　要：基于阻燃剂ANTI-660及抗静电剂单苷酸甘油酯(Gm)制备了聚丙烯(PP)复合材料,采用水平垂直燃烧测试仪、氧指数测试仪、表面电阻测定仪、万能试验机和摆锤式冲击试验机等研究了阻燃剂和抗静电剂对复合材料阻燃性能、抗静电性能和力学性能的影响。结果表明,在阻燃剂含量为18.0%(质量分数,下同),抗静电剂含量为2.0%时,复合材料的极限氧指数(LOI)达到26.0%,UL 94测试达到V-0级,表面电阻下降到1.7×10^(12)Ω;添加阻燃抗静电体系的复合材料相比于添加纯阻燃剂的复合材料整体力学性能改变不明显,但仍具有较好的综合力学性能。Polypropylene(PP)composites were prepared based on a fire retardant ANTI-660 and an antistatic agent glyceryl monoacetate(Gm).The effects of flame retardant and antistatic agent on the flame retardant,antistatic and mechanical properties of the composites were characterized using horizontal and vertical combustion tester,oxygen index tester,surface resistance tester,universal testing machine and pendulum impact testing machine.The result indicated that with the addition of 18.0 wt%fire retardant and 2.0 wt%antistatic agent,the limiting oxygen index of the composites reached 26.0 vol%,their vertical combustion reached a V-0 classification,and their surface resistance decreased down to1.7×10^(12)Ω.There is no obvious difference in mechanical properties between the composite system with only a flame retardant and the system with both of the flame retardant and antistatic system.However,the composites with both of additives still keep high comprehensive mechanical performance.
