High-hardness composite material for motor vehicles

Abstract

The invention discloses a high-hardness composite material for motor vehicles. The composite material comprises the following substances in parts by weight: 20-30 parts of PP (polypropylene), 15-25 parts of PS (polystyrene), 35-45 parts of ABS (acrylonitrile butadiene styrene), 15-20 parts of PVC (polyvinyl chloride), 14-19 parts of graphite powder, 10-15 parts of dispersing agent, 20-30 parts of thickener, 10-25 parts of flame retardant, 10-15 parts of defoamer, 14-26 parts of bactericide, 10-19 parts of mica powder, 25-30 parts of high-elasticity rubber, 1-3 parts of manganese, 1-8 parts of nickel and 1-7 parts of phosphorus. The composite material has the beneficial effects that the composite material has good mechanical performance, can play a role of elastic buffering when cars are subjected to impact and can be used for bumpers of cars, car body shells and the like.

Description

technical field [0001] The invention relates to a high-hardness composite material for motor vehicles. Background technique [0002] There are many accidents in automobiles now, and the parts where automobiles often collide are bumpers and automobile bodies. At present, the main materials used are mostly polypropylene. The disadvantage is that the mechanical properties are poor, and its anti-collision performance cannot meet the ideal requirements. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a high-hardness composite material for motor vehicles. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A high-hardness composite material for motor vehicles, characterized in that it includes the following parts by weight: 20-30 parts of PP, 15-25 parts of PS, 35-45 parts of ABS, 15-20 parts of PVC, 14-19 parts of graphite powder, a...
