| 摘 要： | 研究了橡胶、增塑剂、矿物填料和表面处理剂对橡胶／聚氯乙烯(PVC)共混物力学性能的影响，用扫描电镜分析了有机胺类表面处理剂改性高岭土／丁腈橡胶(NBR)／PVC的界面结合状况。结果表明，当NBR用量为30份，邻苯二甲酸二辛酯用量为60份，有机胺类表面处理剂质量分数为3％，填充60份的超细碳酸钙或高岭土或牌号为SMF的蒙脱土时，可得到力学性能较佳的NBR／PVC共混物；不同矿物填料对NBR／PVC共混物的增强作用不同，经有机胺类表面处理剂改性后，以超细碳酸钙、高岭土和蒙脱土SMF的增强效果最为明显。

| Abstract: | The effects of rubber,plasticizer,mineral filler,and surface treating agent on mechanical properties of rubber/poly(vinyl chloride)(PVC) blends were studied.The interface combination of kaolin modified by organic amine surface treating agent/nitrile rubber(NBR)/PVC blends was analyzed by scanning electron microscope.The results showed that the mechanical properties of NBR/PVC blends was better when the amount of NBR was 30 phr,dioctyl phthalate was 60 phr,mass fraction of organic amine surface treating agent was 30%,superfine calcium carbonate or kaolin or montmorillonite(its brand was SMF) was 60 phr.The reinforcement of rubber/PVC blends varied from mineral filler to mineral filler.The reinforced effect of rubber/PVC blends was obvious after filling superfine calcium carbonate or kaolin or montmorillonite SMF. |
