Abstract

The invention relates to a polypropylene combination with anti-scoring property. The polypropylene combination is characterized in that the invention consists of the following raw materials by weight part: 40 to 100 parts of polypropylene, 0.5 to 5 parts of maleic anhydride or glyceryl methacrylate copolymer or graft Alpha- olefin copolymer, 0.2 to 2 parts of aliphatics acid amide, 0 to 40 parts of mineral filler, 0 to 20 parts of toughening agent, 0.1 to 1 part of antioxidant agent, and 0.1 to 1 part of retardant agent. The polypropylene combination of the invention is provided with good aging-resistant, flame retardant and anti-scoring properties, and is used for vehicle inner decorating pieces, home appliances shells, etc.

Description

technical field [0001] The invention relates to a polypropylene composition with scratch resistance and a preparation method thereof, which is applied in the fields of automobile, home appliance and machinery industry, and belongs to the technical field of polypropylene modification. Background technique [0002] Due to its light weight, solvent resistance, easy processing, excellent mechanical properties, and easy recycling, polypropylene has been widely used, especially in the automotive industry, home appliances and machinery. In the future, the automobile industry will develop in the direction of energy saving, environmental protection and safety. This requires the materials used to be light in weight, simple to process, easy to recycle, etc., and polypropylene meets these requirements. However, due to the lower surface hardness and poor scratch resistance of polypropylene materials compared with other materials, it cannot meet the requirements of automotive interior pa...
