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

The invention discloses a polypropylene mica master batch as well as a preparation method and application thereof, and belongs to the technical field of plastic processing aids. The polypropylene mica master batch comprises the following components in parts by weight: 10-25 parts of homopolymerized high melt index polypropylene, 10-25 parts of metallocene low isotacticity polypropylene, and 75-90 parts of mica. By adding a small amount of metallocene low-isotacticity polypropylene, a highlight surface is easy to form, so that the glossiness of the polypropylene mica master batch is improved. Meanwhile, through the synergistic effect of homopolymerized high-melt-index polypropylene, the dispersity of a mica master batch system is improved while the glossiness value is effectively improved, the polypropylene mica master batch with high mica content and high glossiness is prepared, the glossiness can reach 79.6, and the first-level dispersion effect can be achieved. 本发明公开了一种聚丙烯云母母粒及其制备方法和应用，属于塑料加工助剂技术领域。聚丙烯云母母粒，
