摘　　要：为了提高聚苯乙烯(PS)的阻燃性能,降低其燃烧过程中的热释放和烟雾释放,通过静电自组装法制备一种新型阻燃剂(MAP),并将MAP-聚磷酸铵(APP)-季戊四醇(PER)组成的新型膨胀型阻燃剂(N-IFR)与硼酸锌(ZB)复配后添至PS中。结果表明:PS-22%N-IFR/1%ZB复合材料的极限氧指数提高至28.3%,垂直燃烧测试达到UL-94 V-0等级。与纯PS相比,其峰值热释放速率、总热释放量和总烟释放量分别下降67.6%、11.8%和25.9%。ZB与N-IFR的协同阻燃作用促进了高质量炭层的形成,并有效抑制了PS基体的热释放与烟释放。To enhance the flame retardancy of polystyrene(PS),reducing its heat and smoke release during combustion,a novel flame retardant(MAP)was prepared via electrostatic self-assembly,and the new intumescent flame retardant(N-IFR)composed of MAP-polyphosphoric ammonium(APP)-pentaerythritol(PER)was compounded with zinc borate(ZB)and added to PS.The results showed that the limiting oxygen index of PS-22%N-IFR/1%ZB composites increased to 28.3%,achieving UL-94 V-0 rating in vertical burning tests.Compared to pure PS,the peak heat release rate,total heat release,and total smoke production decreased by 67.6%,11.8%and 25.9%,respectively.The synergistic flame retardant effect of ZB and N-IFR promoted the formation of a high-quality char layer and effectively suppressed the heat and smoke release of the PS.
