[0004] At present, there are relatively few studies on the indentation resistance of polypropylene materials, and most of the research focuses on improving the scratch resistance of materials. For example, Chinese patent CN201610374640.8 discloses a scratch-resistant polypropylene compound and its preparation method ; Patent CN201410135179.1 discloses a polypropylene composition with scratch resistance and high-gloss spray-free aesthetic effect and its preparation method and application; Patent CN201110283014.5 discloses a scratch-resistant and stress-resistant whitening polypropylene Compositions and their preparation methods, most of these patents improve the scratch resistance of polypropylene materials by adding scratch-resistant agents such as amides or polysiloxanes

Abstract
The invention discloses a polypropylene material with excellent indentation resistance and a preparation method of the polypropylene material. The polypropylene material is prepared from raw materialsin percentage by weight as follows: 68%-89% of polypropylene, 0-15% of talc powder, 5%-15% of mica, 4%-10% of high density polyethylene, 0.1%-1% of an antioxidant and 0.1%-2% of other additives. Thepolypropylene material has the advantages as follows: 1, the indentation resistance of the polypropylene material is effectively improved with a method of partially replacing talc powder with mica with large radius-thickness ratio; 2, due to addition of high density polyethylene, polypropylene crystals are refined, the indentation depth of the material can be reduced, and the indentation resistance of the material can be improved; 3, the method for preparing the polypropylene material with indentation resistance is simple and feasible and facilitates production.
Description
technical field [0001] The present invention relates to a polypropylene material with excellent anti-indentation performance and its preparation method, more specifically, the compression resistance of the polypropylene material is improved by using mica with a high aspect ratio to partially replace talcum powder and using high-density polyethylene The invention belongs to the technical field of polymer material modification and processing. Background technique [0002] Polypropylene (PP) has become the fastest-growing general-purpose plastic in recent years because of its abundant raw material sources, cheap price, good comprehensive performance, and easy processing and recycling. It is widely used in the automotive industry, electronic appliances, daily necessities, and furniture packaging. and other fields. With the continuous expansion of the application range of polypropylene materials, the technical requirements for modified polypropylene materials are also getting hi...
