Problems solved by technology

Polyphenylene sulfide itself 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. At the same time, in aerospace, petrochemical In the field of static electricity, the generation of static electricity will lead to great production safety problems, so the materials used in these industries are required to have excellent antistatic properties, and the application of polyphenylene sulfide is greatly restricted

Abstract

The invention relates to the technical field of polymer materials, and discloses a high-strength antistatic polyphenylene sulfide material and a preparation method thereof. The material is prepared from following components by weight: 45-55 parts of polyphenylene sulfide, 45-55 parts of glass fiber, 0.2-0.4 part of a lubricant, 0.2-0.4 part of an antioxidant, 0.6-1 part of a coupling agent and 0.5-1 part of an antistatic agent. The preparation method comprises steps of mixing uniformly the 45-55 parts of the polyphenylene sulfide, the 45-55 parts of the glass fiber, the 0.2-0.4 part of the lubricant, the 0.2-0.4 part of the antioxidant, the 0.6-1 part of the coupling agent and the 0.5-1 part of the antistatic agent at a high speed by a high-speed mixer, adding the mixture into a screw extruder, and stretching and pelletizing by the screw extruder to obtain a product. The material has permanent antistatic performance, and the cost of the material is largely reduced because of addition of the low-cost glass fiber, thus extending the application range of the material largely.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-strength antistatic polyphenylene sulfide material and a preparation method thereof. Background technique [0002] Polyphenylene sulfide (PPS) is a special engineering plastic with excellent comprehensive properties.
