Title:

SOLID LUBRICANT AND SLIDING MEMBER HAVING SOLID LUBRICANT EMBEDDED THEREIN

Document Type and Number:

WIPO Patent Application WO/2013/168507

Kind Code:

A1

Abstract:

Provided are: a solid lubricant having a low friction coefficient and excellent abrasion resistance; and a sliding member having this solid lubricant embedded therein. The solid lubricant (4) has a sea-island structure, comprising: a sea phase as a continuous phase, containing a hydrocarbon-based wax and a polyethylene resin; and an island phase as a dispersion phase, containing a low-molecular weight tetrafluoroethylene resin, a higher fatty acid salt, a phosphate of a basic nitrogen-containing compound, and zinc stannate. A high-molecular weight tetrafluoroethylene resin is contained in this continuous-phase sea phase in a fibrous and mesh state. The hydrocarbon-based wax content is 30-60 vol%, the polyethylene resin content is 3-10 vol%, the low-molecular weight tetrafluoroethylene resin content is 10-30 vol%, the higher fatty acid salt content is 20-40 vol%, the basic nitrogen-containing compound phosphate content is 0.5-5 vol%, the zinc stannate content is 0.5-5 vol%, and the high-molecular weight tetrafluoroethylene resin content is 1-10 vol%.
