摘　　要：采用熔融共混法制备了纳米锡酸锌/丙烯腈-丁二烯-苯乙烯共聚物(ABS)/聚氯乙烯(PVC)复合材料。并对复合材料的冲击强度、阻燃性能进行了测试。结果表明,纳米锡酸锌不但可以提高复合材料的缺口冲击强度,还可以改善复合材料的抑烟阻燃性能。特别是当纳米锡酸锌添加量为6份时,复合材料的阻燃抑烟性能最佳。与未添加纳米填料时相比,纳米锡酸锌/ABS/PVC复合材料的缺口冲击强度达到69．93 kJ/m^2,提高幅度达49．71%。扫描电镜(SEM)分析表明,当纳米锡酸锌在6份时,其在复合材料中呈纳米级分散,且与塑料基体结合良好。The nano-zinc stannate/ABS/PVC composites was prepared by melting blending method. The impact strength and the flame retardancy of the composites were tested. The results indicate that nano-zinc stannate can not only improve the impact strength of the composites, but also improve the smoke restrin properties and the flame retardancy of the composites. Especially when the content of nano-zinc stannate is 6 phr,the best flame retardancy and smoke restin property of the composites can be achieved. Compared with ABS/ PVC,the impact strength of nano-zinc stannate/ABS/PVC composites increases by 49.71 and reaches 69.93 kJ/m^2. SEM analysis exhibits that nano-zinc stannate disperses at a nano sized state in the matrix and has a good compatibility with the resin when nano-zinc stannate is 6 phr.
