Abstract

The invention belongs to the field of high-molecular materials and particularly relates to a temperature-resisting nanometer bauxite 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, 4-6 parts of octadecanamide, 13-15 parts of white carbon black, 1-1.5 parts of stearic acid, 1-2 parts of antioxidant BHT (Butylated Hydroxytoluene), 10-15 parts of diatomite, 12-14 parts of nanometer bauxite, 3-5 parts of isopropyl tri(dioctyl pyrophosphate acyloxyl) titanate, 4-7 parts of polyethylene wax powder and 12-15 parts of additive. According to the temperature-resisting nanometer bauxite modified polyphenylene sulfide material disclosed by the invention, the polyphenylene sulfide is modified by use of the raw materials such as the nanometer bauxite and the diatomite, and the improved material has good processing performance and mechanical properties; a prepared material is firm, capable of resisting high temperature and low temperature as well as low-temperature impact, relatively high in thermal deformation temperature, good in barrier property, oil-resisting, water-proof, self-lubricated, safe and reliable in use and widely applicable to manufacturing of various plastic parts for automobiles.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a temperature-resistant nano-bauxite-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 purpos...
