摘　　要：以新近推出的Orient系列膨胀阻燃剂(IFR)为主体,研究其在不同型号的聚丙烯材料中的阻燃性能、耐水性能及灼热丝性能。实验表明:Orient IFR在不同型号聚丙烯中添加19%～31%(质量分数)时,就可以通过UL94 V-0级阻燃测试,但聚丙烯的结构和熔体质量流动速率对于阻燃剂的添加量有一定程度的影响。少量的抗滴落剂可以提高熔体强度,从而提高材料的阻燃性能,降低阻燃剂添加量。P603牌号的阻燃剂有很好的耐水性能,1.6mm和0.8 mm样条能通过UL746C试验。Orient系列阻燃剂有良好的耐燃性,均可通过850℃灼热丝试验。Effects of Orient IFR on flame retardancy, water resistance and glow wire property test of different types of polypropylene resins were investigated. The experimental results demonstrated that the samples of different types of polypropylene could pass UL94V-O with 19 wt% - 31 wt% Orient IFR. The addition amount of Orient IFR was confirmed to be effeeted by the melt index and the structure of polypropylene. A small amount of drip resistant agents could improve the melt strength and flame retardance, and reduce the loading of Orient IFR. The flame retardant of P603 showed an excellent water resistance, of which both 1.6 mm and 0. 8 mm samples could pass UL746C test. Orient IFR also presented superior flame retardance and could pass glow wire test at 850 ℃.
