Abstract
The invention belongs to the field of a high-molecular material and particularly relates to an isotactic polypropylene modified polyphenylene sulfide material for an automobile plastic part. The material is prepared from the following raw materials in parts by weight: 100 parts of polyphenylene sulfide, 14-16 parts of antimonous oxide, 17-19 parts of isotactic polypropylene, 12-14 parts of diatomite, 4-5 parts of ammonium dihydrogen phosphate, 10-12 parts of tung oil, 2-3 parts of zinc oxide, 4-5 parts of coumarone, 1-2 parts of an accelerator DM, 2-3 parts of calcium lignosulphonate, 5-7 parts of polyvinyl alcohol and 12-15 parts of an additive. The isotactic polypropylene modified polyphenylene sulfide material disclosed by the invention integrates the advantages of the raw materials such as the polyphenylene sulfide, the isotactic polypropylene and the diatomite, so the prepared material is high in intensity, good in rigidity, resistive to high temperature and impact, retardant to fire, good in insulativity, safe and reliable in use, widely applicable to the manufacturing of various plastic parts for automobiles, and especially applicable to automobile parts in relatively high-temperature environment.
Description
technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to an isotactic 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 the rigidity decreases very little 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 ...
