摘　　要：研究了丙烯腈-丁二烯-苯乙烯共聚物(ABS)与甲基丙烯酸甲酯-丁二烯-苯乙烯共聚物(MBS)复配对聚氯乙烯(PVC)/滑石粉合金耐热性能和力学性能的影响,同时比较了滑石粉经硅烷偶联剂改性前后合金性能的差异,并通过SEM观察分析了合金的冲击断面微观形貌和填料的分散情况。结果表明:ABS/MBS中各组分含量若发生改变,则会对合金的耐热性能和力学性能均产生较大的影响;改性后的滑石粉更有助于提高合金的耐热性能和力学性能。The influences of different combination of ABS and MBS on mechanical property and heat resistance property of PVC/talc alloy were studied, and the performance differences of the alloys which filled with unmodified talc powder and the powder modified by silane coupling agent were compared. The micro-morphology of impact surface and the dispersion of the inorganic filler of the alloy were analyzed by SEM. The results show that： with the variation of content of each component in ABS/MBS, the heat resistance and mechanical properties of the alloy are affected obviously. The modified talc powder will do a lot more help to improve the heat resistance and the mechanical properties of the alloy.
