Problems solved by technology

At present, the impact resistance and dimensional stability of automobile plastic bumpers on the market are poor, which will lead to dangerous riding; the bumper will change color and deformation under high temperature; and the impact resistance is not high, the shrinkage rate is too large, and the size is unstable The plastic bumper materials of automobiles have not met people's requirements for safety
Therefore, people add various fillers or additives to modify it. However, many modification effects are not ideal. It is difficult to improve the impact performance and rigidity of materials by adding various additives in the same material system.

Abstract

The invention discloses a method for preparing polyphenyl ether plastic particles for automobile bumpers. The method comprises the following steps that all components are weighed according to a weight part ratio and then are placed in a high-speed mixer to be stirred and mixed; then the evenly mixed materials are added into a double-screw extruder to be molten, plasticized, extruded and pelletized, and then the polyphenyl ether plastic particles are obtained. The polyphenyl ether plastic materials manufactured through the method are high in surface strength, good in stretch resistance, good in acid and alkali corrosion resistance and good in water resistance, can be used for manufacturing the bumpers at the front end and the rear end of the interior of an automobile, and is high in environmental friendliness, low in weight and capable of achieving the low weight of the automobile easily.
