Problems solved by technology

However, because the mica powder has a flake structure, it is easy to bridge in the actual processing process, and there will be a phenomenon that the material will not be cut.
In addition, in order to maintain the flaky structure of mica powder, manufacturers on the market usually use wet processing methods to obtain mica powder by grinding. Such powder contains a large amount of metal ions and is not resistant to aging.

Abstract

The invention discloses a polypropylene material having scratch resistance and indentation resistance and a preparation method thereof. The polypropylene material includes polypropylene, talcum powder, toughening agent, high density polyethylene (HDPE), silicone masterbatch, antioxidant, polytetrafluoroethylene and auxiliary agent. The preparation method includes evenly mixing the components to obtain the polypropylene material. According to the polypropylene material having scratch resistance and indentation resistance and the preparation method thereof, the indentation resistance of the polypropylene material is effectively improved, the surface friction coefficient of the polypropylene is reduced, the scratch resistance is improved, the method is simple and feasible, and the polypropylene material is easy to produce.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polypropylene material with anti-scratch and anti-indentation properties and a preparation method thereof. Background technique [0002] With the increasing development and growth of the automobile industry, lightweight and replacing steel with plastic have become the main theme of the automobile industry. Modified polypropylene has been widely used in the interior and exterior decoration of automobiles, and the requirements for the appearance and performance of automobile interior and exterior decoration materials have also been continuously improved. [0003] Polypropylene interior and exterior trims are prone to collisions during use, assembly, and transportation, resulting in color differences at the collision parts and affecting product appearance. At present, the surface can be smoothed and the surface friction coefficient can be reduced by adding amides or pol...
