Abstract

The invention belongs to the field of the high polymer materials and specifically relates to a low-cost polyethylene modified polyphenyl ether material for automobile plastic parts. The material is prepared from the following raw materials in parts by weight: 100 parts of polyphenyl ether, 16-19 parts of recycled polyethylene, 2-3 parts of isopropyl tri(dioctyl pyrophosphoric acyloxy) titanate, 2-4 parts of magnesium oxide, 3-5 parts of molybdenum disulfide, 2-4 parts of barium stearate, 1-3 parts of methyltrimethoxysilane, 10-12 parts of kaoline powder, 10-15 parts of polytetrafluoroethylene, 5-7 parts of epoxidized butyl oleate and 12-15 parts of auxiliaries. The low-cost polyethylene modified polyphenyl ether material integrates the advantages of the raw materials such as polyphenyl ether, polyethylene and polytetrafluoroethylene, and thus has excellent processability and mechanical property; the prepared material is firm, flexible, waterproof, moisture-proof, heat aging-resistant, has excellent electrical properties, good chemical stability and self lubricating property, is hard and durable, and can be widely applied to manufacturing of various automobile plastic parts, and furthermore, the production cost is reduced and the waste of resources is avoided.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a low-cost polyethylene-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 pres...
