摘　　要：研究了无机填料针状硫酸镁晶须(MSW)和片状滑石粉(TAL)对PVC/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,当TAL用量为70份时,PVC/ABS合金维卡软化温度达到102.2℃。在MSW和TAL复配中,MSW对PVC/ABS合金有很好的增强效果并对缺口冲击强度影响较大。The effect of inorganic fillers needle-shaped magnesium sulfate whisker （MSW） and Talc on the mechanical property, Vicat softening temperature and processing property of PVC/ABS composite were studied in this paper. The micro-morphology of impact surface and the dispersion of the inorganic filler of PVC/ABS were analyzed by using SEM. The results showed that： the Vicar softening temperature of PVC/ ABS composite was 102. 2 ℃ when 70 phr Talc was added. In the MSW and Tale composite, MSW had a good reinforcing effect and great influence on the notched impact strength on PVC/ABS composite.
