摘　　要：采用长纤维增强热塑性复合材料在线模压成型(LFT-D)方法将α-ZrP改性无卤阻燃聚丙烯与玻璃纤维熔融共混,并分别研究了磷酸锆(α-ZrP)、玻璃纤维、相容剂马来酸酐接枝聚丙烯(MAPP)含量对复合材料阻燃性能和力学性能的影响。结果表明:α-ZrP能明显地提高复合材料的阻燃和力学性能;玻璃纤维可以在一定范围内提高复合材料的阻燃和力学性能;相容剂可以在一定限度内提高复合材料的力学性能。The polypropylene(PP)intumescent flame retardant modified by α-ZrP were blended with glass fibre by LFT-D method.The effect of α-ZrP,glass fibre,MAPP on flame retardant and mechanical properties of composite was researched.The results shown that the flame retardant and mechanical properties of composites can be obviously improved by α-ZrP.Glass fiber can improve the flame retardant and mechanical properties of composite within a certain limits.The MAPP can improve the mechanical properties of composite within a certain limits.
