摘　　要：研究了无机填料粒状碳酸钙(CaCO3)和片状滑石粉(Talc)对聚氯乙烯(PVC)/丙烯腈-丁二烯-苯乙烯共聚物(ABS)合金的力学性能、维卡软化温度和加工性能的影响,SEM观察PVC/ABS合金的冲击断面微观形貌和无机填料的分散情况。结果表明,CaCO3和Talc复配可以改善PVC/ABS合金的冲击性能和拉伸性能;Talc可以大幅度的提高PVC/ABS合金维卡软化温度;CaCO3和Talc复配不利于PVC/ABS合金维卡软化温度和加工性能的提高。The effect of CaCO3 and Talc as inorganic fillers on mechanical property,Vicat softening temperature and processing property of PVC/ABS composite were studied in this paper.The micro-morphology of impact fracture surface and the dispersion of the inorganic filler were examined by SEM.The results showed that：Composite stabilizer of CaCO3 and Talc can improve the impact property and tensile property of PVC/ABS composite.Talc greatly increased the Vicat softening temperature of PVC/ABS composite.Composite stabilizer of CaCO3 and Talc was disadvantage to improve the Vicat softening temperature and processing property of PVC/ABS composite.
