摘　　要：采用优质煤系高岭土煅烧制备的纳米莫来石(nano-mullite)对聚苯乙烯(polystyrene)进行改性,通过机械共混的方法制备了PS/nano-mullite复合材料。探讨了复合材料中纳米莫来石的含量对改性PS的力学性能、耐热性能以及热流动性的影响。实验结果表明:适量的纳米莫来石加入后,复合材料的拉伸强度,缺口冲击强度,维卡软化点温度和热流动性能均有较大的提高。Polystyrene/nano-mulite composites had been developed based on PS blended with nano- mullite particles. The effects of different content of nano-mullite on the mechanical property .heat-resisting property and heat-fluidness were investigated. The experimental results indicate that the tensile strength, Izod notch impact intensity, Vicat softening point and the heat-fluidness of PS/nanomulite composites are enhanced markedly.
