摘　　要：主要研究了经表面处理和未经表面处理的凹凸棒土对PVC/ABS复合材料力学性能及维卡软化温度的影响,用SEM观察了PVC/ABS复合材料的冲击断面微观形貌和凹凸棒土的分散情况。结果表明:经偶联剂改性后的凹凸棒土对复合材料力学性能的影响要好于未改性的凹凸棒土;未经处理的凹凸棒土对复合材料维卡软化温度有较大的提高。The influences of the attapulgite with surface treatment and without surface treatment on mechanical properties and Vicat softening temperature of PVC/ABS composite were mainly researched,and the impact fracture morphology of PVC/ABS composite and the dispersion of attapulgite in composites were observed by SEM.The results show that： the effect of attapulgite modified by titanate coupling agent on mechanical properties of PVC/ABS composite is better than that of unmodified attapulgite on mechanical properties of composite.The vicat softening temperature of the composite is greatly improved by adding unmodified attapulgite.
