Automotive composite material with high collision preventing performance

Abstract

The invention discloses an automotive composite material with high collision preventing performance. The automotive composite material comprises the following materials in parts by weight: 20 to 30 parts of PP (Polypropylene), 15 to 25 parts of PS (Poly Styrene), 35 to 45 parts of ABS (Acrylonitrile Butadiene Styrene), 10 to 15 parts of dispersing agent, 20 to 30 parts of thickening agent, 10 to 25 parts of fire retardant, 10 to 15 parts of antifoaming agent, 14 to 26 parts of bactericide, 10 to 19 parts of mica powder, 17 to 28 parts of hollow glass microsphere, 14 to 19 parts of graphite powder, 10 to 15 parts of modified polypropylene, 1 to 3 parts of manganese, 1 to 8 parts of nickel, and 1 to 7 parts of phosphorus. The automotive composite material has high mechanical property, can implement elastic buffering while an automobile is collided, and can be applied to a bumper of the automobile, an automobile housing and the like.

Description

technical field [0001] The invention relates to a composite material with high anti-collision performance for automobiles. 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.
