−９８０２８号公報等参照）。2. Description of the Related Art Conventionally, polytetrafluoroethylene resin (hereinafter sometimes abbreviated as "PTFE resin").
Because of its excellent self-lubricating properties, low friction coefficient, and chemical and heat resistance, it is widely used as a sliding material for bearings and the like. When a sliding material made of a PTFE resin is used without lubrication, it is necessary to transfer the PTFE resin to a mating material and slide the PTFE resin with each other. Conventionally, this has been made possible by adding lead (for example, Japanese Patent Publication No. 39-16950,
-98028).

The barium sulfate particles constitute 1 to 30% by volume of the sliding material, preferably 3 to 30%.
Used to account for 15 vol%. If it is less than 1 vol%, the transfer of the PTFE resin to the partner material is small, and the effect of blending barium sulfate is small. If it exceeds 30 vol%, the coefficient of friction increases, and wear increases, which is not preferable.

Preferred examples of the solid lubricant include molybdenum disulfide (MoS 2 ), tungsten disulfide (WS 2 ), graphite, boron nitride, and the like. The graphite may be either natural or artificial graphite, but natural graphite is preferred from the viewpoint of friction characteristics. The average particle size of the solid lubricant is preferably 15 μm or less, more preferably 0.2 to 1 μm.
0 μm. Among them, molybdenum disulfide and graphite are particularly preferable, and it is preferable that at least one of them is added.

The solid lubricant is 5 to 40 vol% of the sliding material, preferably 10 to 10 vol%.
Used to account for 30 vol%. If it is less than 5 vol%, the abrasion resistance is not good, and the effect of blending the solid lubricant is small. If it exceeds 40% by volume, the coefficient of friction increases, which is not preferable.

ある。In the sliding material of the present invention, a sliding member is manufactured by forming a sliding layer on a base material. As the base material of the sliding member, a material obtained by sintering a copper alloy, for example, copper tin, copper lead tin, phosphor bronze, or a mixed powder of iron, copper, and tin on a steel plate, is used. Then, after impregnating the mixture of each component constituting the sliding material into the porous sintered layer, moisture is removed by drying,
By baking at 350 to 400 ° C., a sliding layer is formed on the substrate. Sliding layer thickness on steel plate is 80-4
It is 00 μm, preferably 120 to 350 μm. Further, the porous sintered layer is preferably not exposed on the outermost surface of the sliding layer, but may be exposed. A steel plate alone may be used as the base material of the other sliding member. In this case, a roughening treatment such as shot blasting may be performed on the steel plate, and the sliding material may be directly applied to the roughened portion. As a coating method, means such as spraying, tumbling, roll transfer, and printing are used. The thickness of the coating surface is preferably 10 to 50 μm,
More preferably, it is 20 to 30 μm. Further, a wire net may be used without using a steel plate as the base material. In the case of a wire mesh, it is basically the same as the method of impregnating the porous sintered layer.
