Abstract

The invention discloses a polypropylene composite material for automotive interior parts and a production process of the polypropylene composite material for the automotive interior parts. The polypropylene composite material for the automotive interior parts is prepared from, by weight, 55-80 parts of homo-polypropylene, 6-12 parts of ethylene-propylene-diene monomer rubber, 15-25 parts of talcumpowder, 0.2-0.8 part of a light stabilizer, 5-7 parts of a compatibilizer, 0.8-1.2 parts of a coupling agent, 0.3-0.6 part of an antioxidant, 5-8 parts of a flame retardant, 3-6 parts of an antibacterial and 0.2-2.1 parts of an adsorbent. Compared with the prior art, the polypropylene composite material for the automotive interior parts has advantages of great antibacterial and fame retardation performances, low VOC (volatile organic compound) and the like. In addition, the polypropylene composite material for the automotive interior parts has appearance and performances of rubber and can bemade into the automobile interior parts such as driver's seat outer lateral plates, small cover caps, lateral plate inner plates, inner lateral plate plastic parts, passenger seat outer lateral plates, door sheet armrest frameworks, door embedded decorative plate frameworks, door embedded decorative plates and the like through an injection molding process.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a polypropylene composite material for automobile interior decoration and a production process thereof. Background technique [0002] Polypropylene, abbreviated as PP, was first put into industrial production in Italy in 1957 and is another important plastic species after polyethylene (PE). It has good heat resistance, and it will not be destroyed when it is cooked at 135°C for 1000 hours. The specific heat capacity and thermal conductivity of PP are smaller than that of PE, but its thermal insulation is better than that of PE. PP is a non-polar polymer with excellent dielectric and electrical insulation properties. The electrical properties are basically not affected by ambient humidity and electric field frequency. Within the allowable operating range, the increase in temperature will reduce the electrical properties. Its High arc resistance. PP has good chemical resistance, and other...
