Polypropylene toughening master batch as well as preparation method and application thereof

The invention relates to the technical field of preparation of filling master batches, in particular to a polypropylene toughening master batch as well as a preparation method and application thereof. Nano calcium carbonate, nano silicon dioxide and nano montmorillonite are mixed, and a silane coupling agent is used for modifying the mixed powder to obtain the modified composite powder filler. And then mixing polypropylene resin, maleic anhydride grafted polypropylene wax, polyethylene wax, an aluminate coupling agent, calcium stearate and the prepared modified composite powder filler, mixing and extruding to obtain the polypropylene toughening master batch. When the polypropylene toughening master batch is applied to modification of a non-woven fabric raw material, the toughness and comprehensive performance of the material can be improved on the basis of reducing the production cost. 本发明涉及填充母粒的制备技术领域，尤其涉及一种聚丙烯增韧母粒及其制备方法和应用。本发明使用纳米碳酸钙、纳米二氧化硅和纳米蒙脱土三种粉体混合，并使用硅烷偶联剂对混合粉体进行改性得到改性复合粉体填料。随后将聚丙烯树脂、马来酸酐接枝聚丙烯蜡、聚乙烯蜡、铝酸
