Abstract

The invention belongs to the field of high molecular materials and particularly relates to a polyphenyl ether modified polyphenylene sulfide material for an automotive plastic part. The material is prepared from the following raw materials in parts by weight: 100 parts of polyphenylene sulfide, 14-18 parts of polyphenyl ether, 4-5 parts of carbodiimide, 3-5 parts of aluminum citrate, 1-2 parts of silane coupling agent KH-550, 1-2 parts of di(2-Ethylhexyl)-4,5-epoxycyclohexane-1,2-dicarboxylate, 2-3 parts of chitosan, 12-15 parts of white carbon black, 1-2 parts of silicon carbide and 12-15 parts of assistant. The material provided by the invention combines the advantages of the raw materials such as polyphenylene sulfide and polyphenyl ether and improves the performances of conventional nylon materials, so that the material has good processing and mechanical performances. The prepared material is firm and wear-resistant, high-temperature resistant and waterproof, good in electric insulating performance, flame-retardant and safe and reliable to use, and can be widely applied to preparing various automotive plastic parts.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a polyphenylene ether-modified polyphenylene sulfide material for automobile plastic parts and a preparation method thereof. Background technique [0002] PPS resin has high strength and high rigidity, and has little rigidity reduction under high temperature conditions, and has excellent fatigue resistance and creep resistance; it is widely used in auto parts and has good development potential and competitiveness. However, polyphenylene sulfide resin also has the disadvantages of high brittleness, poor toughness, and low impact strength, so its application is limited to a certain extent. [0003] In order to improve the performance of PPS resin materials and broaden the scope of use of materials, it is necessary to modify PPS resin materials so that they can be widely used in various parts of automobiles. Contents of the invention [0004] The purpose of the presen...
