Abstract

The invention belongs to the technical field of polymer materials, and relates to a polyphenylene sulfide material and a preparation method thereof. The composite material is composed of the following raw materials in parts by weight: 45 to 55 parts of polyphenylene sulfide, 5 to 10 parts of anti-wear agent, 0.5 to 1 part of lubricant, 0.2 to 0.4 part of antioxidant, 0.6 to 1 part of coupling agent, and 35 to 45 parts of glass fiber. The preparation method comprises the following steps: adding 45 to 55 parts of polyphenylene sulfide, 5 to 10 parts of anti-wear agent, 0.5 to 1 part of lubricant, 0.2 to 0.4 part of antioxidant, 0.6 to 1 part of coupling agent, and 35 to 45 parts of glass fiber into a high-speed mixer, evenly mixing the materials in a high speed in the high-speed mixer, then pouring the mixture into a screw extruder, extruding the mixture strips, and cutting the strips into granules so as to obtain the finished product. The material has the advantages of high strength, self-lubricating, and wear resistance, and can be made into gears, bearings, and the like.
