A series of wear and flame resistant polyamide 6 (PA6) composites were prepared using glass fiber (GF) and talc (T) as reinforcer, polytetrafluoroethylene (PTFE) and graphite (Gr) as solid lubricants, red phosphorus (RP) and zinc borate (ZB) as flame retardant. The tribological property, mechanical property, flame retardant property and the flame retardant mechanism were investigated. The tests show that the formula of the wear resistant PA6 composite (WRPA 6) is PA6/GF/T/PTFE/Gr in the ratio of 100/15/5/10/5 by mass. Because this composite exhibits the lowest friction coefficient (0.1429) and...

采用玻璃纤维(GF)、滑石粉(T)为增强体,聚四氟乙烯(PTFE)和石墨(Gr)为固体润滑剂,红磷(RP)和硼酸锌(ZB)为阻燃剂制备了一系列耐磨阻燃的聚酰胺6(PA6)复合材料。研究了复合材料的摩擦磨损性能、力学性能、阻燃性能及阻燃机理。结果表明,耐磨材料(WRPA6)配方是质量比为100/15/10/5的PA6/GF/T/PTFE/Gr 复合材料,该材料的摩擦因数为0.1429,且没有检测到质量损失。RP 和ZB 可以提高WRPA6的阻燃性能,RP 和ZB 有协同作用。当WRPA6含有4份ZB和12份RP 时达到最大极限氧指数30.2vol%和UL94V-0级,阻燃机理为气相阻燃和凝聚相阻燃。
