Abstract

The invention discloses an anti-yellowing antibacterial polypropylene plastic for automobile decorations. The plastic contains the following raw materials in parts by weight: 100 parts of polypropylene, 20-40 parts of polystyrene, 10-20 parts of nitrile rubber, 15-25 parts of nanometer calcium carbonate, 1-5 parts of titanium dioxide, 5-10 parts of shell powder, 1-3 parts of octaphenyl cage-like silsesquioxane, 1-3 parts of polyoxyethylene stearate, 0.5-1.5 parts of composite antibacterial agent, 1-3 parts of coupling agent, 0.5-2 parts of crosslinking agent, 0.5-2 parts of anti-aging agent, 0.5-2 parts of plasticizer, 1-2 parts of stabilizer and 1-3 parts of processing aid. The polypropylene plastic disclosed by the invention has the advantages of high strength, high impact resistance, good antibacterial effect, good heat resistance, good weather resistance, aging resistance, yellowing resistance and the like and can be processed into various automobile interior parts.

Description

technical field [0001] The invention belongs to the technical field of plastics, in particular to a yellowing-resistant and antibacterial polypropylene plastic for automobile accessories. Background technique [0002] PP, also known as polypropylene, is a semi-crystalline material. It is harder and has a higher melting point than polyethylene (PE) plastic. PP resins have excellent moisture absorption resistance, acid and alkali corrosion resistance, and solubility resistance. Because plastic has the advantages of light weight, no rust, and good insulation, it is one of the fastest-growing varieties of general-purpose thermoplastics. PP resin has certain special requirements in the fields of chemical industry, building materials, home appliances, automobiles, etc., but because PP has large spherulites, grain boundary defects and cracks are prone to appear at the spherulite interface, causing embrittlement. PP has the disadvantages of low modulus, low impact strength, and p...
