摘　　要：对2个复合体系聚丙烯/膨胀型阻燃剂(PP/IFR)及聚丙烯/聚烯烃弹性体/纳米碳酸钙/膨胀型阻燃剂(PP/POE/nano-CaCO3/IFR)的阻燃性进行研究,通过测试氧指数、水平燃烧速率、烟密度以及燃烧测试后试样的形貌观察,分析了复合体系的阻燃效果及机理。结果表明,PP/IFR复合体系可达到优异的阻燃性能,IFR用量为30份时氧指数达到34.4%,并且可明显改善PP的熔滴现象。而添加POE破坏了阻燃炭层的形成,降低了氧指数,并伴随严重的熔滴,却能明显降低释烟量。Flame retardancy of two compound systems（PP/IFR and PP/POE/nano-CaCO3/IFR）was studied.By means of testing the LOI,horizontal burning rate,smoke density and observation of specimens tested after combustion,the flame-retardant effect and mechanism of the compound systems were analyzed.The results show that PP/IFR compound stystem gets remarkable flame retardancy.The LOI reaches 34.4% when IFR content is 30 phr.IFR prevents PP melting and dripping.The addition of POE destroys the fire-retardant char layer,LOI is reduced,and accompanying by serious melting and dripping.The amount of smoke release is siynificantly reduce.
