摘　　要：研究了尼龙6(PA6)对红磷、氢氧化镁复配阻燃聚丙烯(PP)复合材料力学性能的影响。采用氧指数(LOI)和热失重法(TGA)分析了PA6对该无卤阻燃PP体系的燃烧及热降解行为的影响。结果表明:PA6的加入提高了该体系的力学性能和热稳定性,并对该无卤阻燃体系具有良好的协效作用。PA6的用量为12份时,该体系的拉伸强度提高了20.5%,分解温度提高了15℃,同时获得了良好的阻燃性。The effects of PA6 on the mechanical properties of PP/Mg（OH）2/red phosphorus composite were studied. The influence of PA6 on the combustion and thermal degradation behaviors of the halogen-free flame retardant PP composites were analyzed by means of LOI and TGA. The results showed the use of PA6 upgraded the mechanical properties and thermal stability of the composite, and PA6 had obvious synergistic effect on the system. When PA6 content was 12 phr, the tensile strength increased by 20.5%, the decomposition temperature rose by 15℃, with better flame retardancy.
