Abstract

The invention belongs to the field of polymer materials, and particularly relates to a wear-resistant polypropylene modified polyphenylene sulfide material for car plastic parts. The material is prepared from the following raw materials by weight: 100 parts of polyphenylene sulfide, 20-23 parts of polypropylene random copolymer, 6-10 parts of carbon black, 1-2 parts of ferric oxalate, 18-22 parts of high abrasion-resistant carbon black N330, 8-12 parts of aluminium hydroxide, 5-7 parts of zinc oxide, 0.3-0.7 part of an accelerating agent DM, 2-3 parts of zinc stearate, 4-6 parts of fatty glyceride, 1-2 parts of butyl mercaptan tin and 12-15 parts of additives. The material combines the advantages of the raw materials of polyphenylene sulfide, polypropylene random copolymer and the like, and adds the raw materials of high abrasion-resistant carbon black N330, and the like for modified processing, so that the material has favorable processability and mechanical properties; the material prepared is high in strength, wear-resistant, heat ageing resistant, flame-retardant, low-temperature tendering resistant, shock-resistant, safe and reliable, and can be widely used for manufacturing various car plastic parts.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a wear-resistant polypropylene-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 t...
