摘　　要：考察了分子筛在自制膨胀型阻燃体系(IFR)中的协效催化作用。利用添加分子筛的IFR对聚丙烯(PP)进行阻燃。运用扫描电子显微镜、垂直燃烧仪等对膨胀阻燃PP体系的表面形态和性能进行了研究。结果表明,阻燃PP加入不同的分子筛后,燃烧级数达到V-0级,氧指数最高增加17.86%,有明显的成炭效果,可获得良好的阻燃性能。The synergism of zeolite in selfmade intumescent flame retardant （IFR） was studied. The IFR containing zeolite was used as the flame retardant of polypropylene（PP）. The surface morphology and property of flame retardanted PP were studied by SEM, UL- 94 vertical burning test. The results showed that followed with adding zeolite to IFR, the flame retardant PP had obvious charring effect, perfect retardancy with UL - 94 rate of V - 0 and the OL increasing 17.86%.
