摘　　要：以分子筛作为协效剂,与未加协效剂的膨胀阻燃剂(RTB-IFR)及其他助剂复配制成膨胀阻燃剂(IFR),用于聚丙烯(PP)的阻燃。研究了添加不同分子筛的IFR对PP的阻燃性能、力学性能及热降解行为的影响。结果表明:4A和H-BETA分子筛的阻燃效果比13X、ZSM分子筛好;分子筛对材料的力学性能影响不大;添加分子筛的阻燃剂改变了IFR和IFR-PP的热降解过程,提高了高温成炭量、炭层的热稳定性和热绝缘性,使IFR-PP的阻燃性能得到提高。Taking zeolites as synergistic agents,the intumescent flame-retardant PP（IFR-PP） was prepared.The effects of different zeolites on the flame retardancy,mechanical properties,thermal degradation of IFR-PP were studied.The results show that the flame retardancy of 4A and H-BETA are better than that of 13X and ZSM;the zeolites have little effects on the mechanical properties of IFR-PP;the addition of zeolites alters the thermal degradation process of IFR and IFR-PP,increases the char residue amount at high temperature,improves the thermal stability and insulation of char layer,and enhances the flame retardancy of IFR-PP.
