Abstract

The invention belongs to the field of special engineering plastics and particularly discloses a polyether-ether ketone composite material. The polyether-ether ketone composite material is characterized by comprising the materials of polyether-ether ketone fine powder, polyether-ether ketone coarse powder, carbon fiber, graphite, polytetrafluoroethylene and a dispersing agent, wherein the mass ratio of the dispersing agent, the carbon fiber, the polytetrafluoroethylene, the graphite, the polyether-ether ketone fine powder to the polyether-ether ketone coarse powder is 1:(11-13):(9-10):(6-8):(7-9):(60-65). The polyether-ether ketone composite material adopts the polyether-ether ketone as a base material, is compounded with a highly-wear-resistant material (carbon fiber), a high-lubricity material (graphite) and a wear-reducing material (polytetrafluoroethylene), comprises the polyether-ether ketone fine powder and the polyether-ether ketone coarse powder and is added with the dispersing agent, so that the fluidity of a product is effectively improved, the stability of the product is improved, the properties of high strength and high wear resistance and the like of the product are further optimized; and the temperature can reach more than 300 DEG C after long-time use, and the melting point is about 356 DEG C, so that the application field of the material is expanded.

Description

technical field [0001] The invention belongs to the field of special engineering plastics, and in particular relates to a polyether ether ketone composite material and a preparation method thereof. Background technique [0002] Special engineering plastics, also known as high-performance engineering plastics, are a class of polymer materials that are mainly used in high-tech fields, have excellent comprehensive properties, and have a long-term service temperature above 150°C. Special engineering plastics have excellent characteristics such as high specific strength and high heat resistance. In recent years, the research on special engineering plastics has developed rapidly. There are many kinds of special engineering plastics that have been industrialized. The main varieties are: polyimide resin (PI ), polyaryletherketone (PAEK), etc. Although the usage of special engineering plastics cannot be compared with that of general-purpose plastics, due to its excellent performance...
