description The invention relates to a PEEK valve-plate composite material with high heat resistance and excellent wear resistance and a preparation method thereof. The material of the invention is a short glass fiber/PTFE/PEEK composite material for gas compressor valve-plates. Innovation of the technology for preparing the composite material is embodied in the following aspects: short glass fiber and teflon are compounded and filled to enhance the PEEK material, teflon is used to raise wear resistance of the PEEK composite material, and a short glass fiber/PTFE/PEEK composite material undergoes blending extrusion by a twin-screw extruder and the extruded product undergoes traction, cooling and grain-sized dicing so as to obtain the modified PEEK valve-plate composite material with high heat resistance and excellent wear resistance. In the field of gas compressor valve-plates, in comparison with a traditional metallic material, the PEEK valve-plate composite material with high heat resistance and excellent wear resistance has high rigidity and high toughness, gives consideration to high dimensional stability, wear resistance and fatigue resistance and also has advantages of raising compressor efficiency and reducing noise.
