Problems solved by technology

[0005] Although the above methods all play a certain role in the scratch resistance of the specific polypropylene composite material system, the imitation metal effect polypropylene composite material is mainly used as a decorative part and appearance part material, which is an easy-to-scratch part. If scratches occur, It directly affects its appearance, so the metal-like effect polypropylene material has very high requirements for scratch resistance, but the scratch-resistant metal-like effect polypropylene composite material is rarely studied and reported

Abstract

The invention discloses a scratch-resistant imitated-metal-effect polypropylene composite material and a preparation method thereof. The scratch-resistant imitated-metal-effect polypropylene composite material is prepared from the following raw materials in percentage by weight: 41-92% of polypropylene, 0-25% of inorganic filler, 0-15% of toughener, 0.1-4% of effect pigment, 0.1-4% of scratch resisting agent, 0.1-1% of light stabilizer and 0.1-1% of antioxidant. By adding a right amount of scratch resisting agent into the imitated-metal-effect polypropylene composite material, the prepared imitated-metal-effect polypropylene has better scratch resistance. Various physical mechanical properties of the prepared imitated-metal-effect polypropylene composite material are basically not influenced on the premise of ensuring the wear resistance of the material. The method for improving the wear resistance of the imitated-metal-effect polypropylene composite material has the advantages of simple preparation technique and low production cost.

Description

technical field [0001] The invention relates to a scratch-resistant metal-imitating polypropylene composite material and a preparation method thereof, which can be used for interior and exterior trim parts of automobiles and belongs to the technical field of polymer modification and processing. Background technique [0002] As people pay more and more attention to environmental protection, a class of imitation metal effect resin that can achieve spraying effect through direct injection molding without spraying is showing its strong competitiveness. The usual way to prepare this kind of imitation metal effect materials is to fill the resin materials with metal pigments and pearlescent pigments to achieve their special color effects. The imitation metal effect resin material can not only bring customers a variety of products, make it maintain a leading edge in the same industry, but also reduce the spraying process from raw materials to finished products that pollute the envir...
