Abstract
A resin composition for a sliding member of the present invention comprises 5 to 40% by weight of barium sulfate; 1 to 30% by weight of a phosphate; 1 to 10% by weight of at least one selected from the group consisting of a polyimide resin, a phenol resin-calcined product and a polyphenylene sulfone resin; and the balance of a polytetrafluoroethylene resin, and a sliding member produced from the resin composition. Such a resin composition suitable for producing a sliding member capable of exhibiting a stable low friction coefficient and an extremely low wear amount under dry frictional condition, or under oil-immersed or oil-lubricated condition.
Claims5
A sliding member comprising:
- a substrate comprising either a steel backing plate with a porous sintered metal layer formed on said steel backing plate, or a metal mesh;
- and
- a resin composition layer formed in pores or meshes of the metal mesh and on the surface thereof, comprising 5 to 40% by weight of barium sulfate, 1 to 30% by weight of a phosphate, 1 to 10% by weight of at least one member selected from the group consisting of a polyimide resin, a phenol resin-calcined product and a polyphenylene sulfone resin, and the balance of a polytetrafluoroethylene resin.
