Japanese Patent Publication No. 58-24648 describes an oleoresin bearing formed from a homogeneous mixture of heat-treated expanded graphite impregnated with lubricating oil, atomized kelmet powder or bronze powder, and a self-lubricating, wear-resistant synthetic resin. ing. In addition, Japanese Patent Publication No. 59-24285 describes a lubricating oil, a norbornene elastomer heat-treated expanded black button as a lubricating oil carrier, a homogeneous mixture of atomized kelmet powder or bronze powder, and a self-lubricating, wear-resistant synthetic resin. The oil-free bearings are described.

各種潤滑油を含浸させることができる。Expanded graphite expands about 200 to 300 times in the C-axis direction by heat-treating it at about 300 to 1000°C. This heat-treated expanded graphite can be impregnated with about 5 g or more of various lubricating oils per 1 g of the expanded graphite, either as it is or after being crushed by pressing.

It is used in proportions such that it accounts for ~30% by weight, with 2 to 30% by weight of tetrafluoroethylene resin and the balance polyacetal resin. Lubricating oil-impregnated heat-treated expanded graphite and tetrafluoroethylene resin are both 2% by weight.
The following compounding ratios still do not sufficiently reduce the coefficient of friction, coefficient of wear, and temperature of sliding parts, and if more than 30% by weight is used, not only will the formability be impaired, but the strength and rigidity will also decrease. Undesirable.The above components are mixed in a Henschel mixer, ribbon mixer, etc. after adding fillers as necessary, and the mixture is kneaded in an extruder, rolls, etc., and then extrusion molded.
Molded into the desired shape by injection molding or the like.
