Abstract

The invention belongs to the field of high-molecular materials, and particularly relates to a toughened low temperature-resisting modified polyphenylene sulfide material applied to an automobile plastic part. The material is prepared from the following raw materials in parts by weight: 100 parts of polyphenylene sulfide, 12-14 parts of ABS (Acrylonitrile Butadiene Styrene) high-rubber powder, 4-6 parts of sodium tungstate, 4-5 parts of magnesium chloride, 2-3 parts of zinc oxide, 1-2 parts of sodium aliphatate, 12-14 parts of polyethylene, 4-5 parts of hydrogenated rosin, 8-12 parts of polyisobutene, 2-3 parts of 3-aminopropyl trimethoxy silane, 2-3 parts of polytetrahydrofuran ether glycol, 4-6 parts of chlorinated paraffin and 12-15 parts of additive. The toughened low temperature-resisting modified polyphenylene sulfide material disclosed by the invention integrates the advantages of the raw materials such as the polyphenylene sulfide 11, the low-density polyethylene and asbestos fibers, so a prepared material is light, wear-resisting, corrosion-resisting, less in possibility of cracking, thermal ageing-resisting, good in color, smooth in hand feeling, beautiful, durable, safe and reliable in use, widely applicable to manufacturing of various plastic parts for automobiles and especially applicable to manufacturing of automobile parts such as tail light covers, automobile roofs and automobile doors.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a toughened and low-temperature-resistant 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 p...
