Problems solved by technology

Polyphenylene sulfide has good strength, but it still cannot meet the requirements in some application industries that require ultra-high strength materials. At this time, materials with higher strength are needed to meet their requirements. When used as bearings or gears in other fields, it is required to have good self-lubricating and wear-resistant properties to ensure the combination with other components, so as to ensure the normal operation of the equipment and small friction damage during use.

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.

Description
