SOLID LUBRICANT AND SLIDING MEMBER HAVING SOLID LUBRICANT EMBEDDED THEREIN

摘要

Provided are a solid lubricant having a low coefficient of friction and excellent wear resistance and a sliding member in which the solid lubricant is embedded. The solid lubricant 4 consists of a sea phase as a continuous phase containing a hydrocarbon wax and a polyethylene resin, and a phase as a dispersed phase containing a low molecular weight tetrafluoroethylene resin, a higher fatty acid salt, a phosphate of a basic nitrogen compound and zinc stannate. A sea island structure is shown, and a high molecular weight tetrafluoroethylene resin is fiber-shaped in the continuous sea phase and contained in a mesh form. The content of hydrocarbon wax is 30 to 60% by volume, the content of polyethylene resin is 3 to 10% by volume, the content of low molecular weight tetrafluoroethylene is 10 to 30% by volume, and the content of higher fatty acid salt is 20 to 40%. It is volume%, content of the phosphate of a basic nitrogen compound is 0.5-5 volume%, content of zinc stannate is 0.5-5 volume%, and content of high molecular weight tetrafluoroethylene resin is 1-10 volume%.
