一种聚丙烯复合材料及制备方法和应用
摘要：
本发明公开了一种聚丙烯复合材料及制备方法和应用，其特征在于各原料按质量百分数的配比为：聚丙烯树脂40％-80％；弹性体5％-15％；二氧化硅5-30％；矿物填料5-30％；耐磨剂1％-10％；润滑剂0.1％-2％；其他添加剂0.1％-5％。本发明的聚丙烯复合材料具有低线性膨胀系数、高耐寒性、高耐磨性等优点，可用于注塑与金属发生摩擦的保温杯内层杯盖注塑件、同时也可应用于注塑家电和汽车部件。
摘要（英）：

The invention discloses polypropylene composite materials, a preparation method and application. The polypropylene composite materials are characterized by being prepared from, by mass percent, the raw materials of 40%-80% of polypropylene resin, 5%-15% of elastomer, 5%-30% of silicon dioxide, 5%-30% of mineral filler, 1%-10% of wear-resistant agents, 0.1%-2% of lubricating agents and 0.1%-5% of other addition agents. The polypropylene composite materials have the advantages of being low in linear expansion coefficient, high in cold tolerance and wear resistance and the like, can be applied to injection molding of both vacuum cup inner layer cup cap injection molding pieces which have friction with metal, and meanwhile can be applied to injection molding of house hold appliances and automobile parts.
