Abstract

The invention belongs to the field of a high-molecular material, and particularly relates to a wear-resisting silicon carbide modified polyphenyl ether material for an automobile plastic part. The material is prepared from the following raw materials in parts by weight: 100 parts of polyphenyl ether, 12-15 parts of silicon carbide, 2-3 parts of a silane coupling agent KH-570, 5-7 parts of trisodium phosphate, 1.2-1.5 parts of ethylene-bis-stearamide, 4-6 parts of wool fat, 1-2 parts of shell powder, 2-3 parts of titanium dioxide, 12-14 parts of magnesium hydroxide and 12-15 parts of an additive. By modifying the polyphenyl ether by use of the raw materials such as the silicon carbide, the wool fat and the titanium dioxide, the mechanical properties of a conventional polyphenyl ether material are improved, and the prepared material is flexible, wear-resisting, heat-resisting, anti-corrosive, good in lubricity, lustrous and bright in surface, easy to be colored, good in formability, safe and reliable in use and widely applicable to the manufacturing of various plastic parts for automobiles.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a wear-resistant silicon carbide modified polyphenylene ether material for automobile plastic parts and a preparation method thereof. Background technique [0002] Polyphenylene oxide (PPO) is one of the five major engineering plastics, with excellent physical and mechanical properties, heat resistance and electrical insulation, low moisture absorption and excellent creep resistance. It is widely used in auto parts and other fields. PPO is an amorphous polymer material. Its melt viscosity is very high and its fluidity is very poor. If it is not modified, it cannot be used because it cannot be processed. [0003] In order to improve the performance of polyphenylene oxide (PPO) materials and broaden the scope of use of materials, it is necessary to improve the formula of polyphenylene oxide (PPO) materials and modify the materials so that they can be widely used in var...
