摩擦条件下での使用を目的とするものである。The sliding members disclosed in these conventional techniques have improved sliding characteristics by blending a certain proportion of PTFE with the base resin, and have improved wear resistance and wear resistance by blending a certain proportion of glass fiber, carbon fiber, etc. They improve mechanical properties and are intended for use under dry friction conditions without supplying lubricating oil to sliding surfaces.

This results in the problem of developing abrasive wear.

It is not clear why the friction and wear characteristics are improved by the addition of phosphate, but in a sliding member in which PTFE and phosphate are simultaneously added to the base resin, the surface of the mating material (sliding) after the sliding friction test is Based on the fact that a lubricating film composed of a base resin, PTFE, and phosphate was formed on the moving surface, the inventors concluded that the effect of this phosphate on improving friction and wear characteristics was due to the lubricating film. It is assumed that this is due to its excellent film-forming properties.

くなりすぎ、返って耐摩耗性を低下させる。Phosphate starts to exhibit a film-forming effect for a lubricating film when the blending ratio is small, for example, 0.5% by weight, and the film-forming effect is maintained up to a blending ratio of 15% by weight. but,
If the amount exceeds 15% by weight, the amount of lubricating film formed will be too large, which will actually reduce the wear resistance.
したがって、リン酸塩の配合割合は0.5〜15重量%
、就中3〜10重量%が好ましい。Therefore, the blending ratio of phosphate is 0.5 to 15% by weight.
, particularly preferably 3 to 10% by weight.
