滑性樹脂組成物に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lubricating resin composition. For more details,
The present invention relates to a lubricating resin composition having excellent lubricity suitable for electrical parts, mechanical parts, etc.
近年、機器類の軽量化ニーズに伴って、金属製品に代っ
て合成樹脂製品が機械部品として数多く用いられるよう
になり、例えば軸受等の摺動部材においても合成樹脂製
品が使用され始めている。In recent years, with the need to reduce the weight of equipment, synthetic resin products have come to be used in many mechanical parts instead of metal products. For example, synthetic resin products have also begun to be used in sliding members such as bearings.
かかる摺動部材においては、従来、摺動性の良い合成樹

、フッ素系樹脂等が用いられている。In such sliding members, polyamide, polyacetal, polyethylene, fluororesin, etc. have conventionally been used as synthetic resins with good sliding properties.

欠点を有する。In low load and low speed ranges, these materials satisfy the required sliding properties even without lubrication, but as the load and high speeds increase, they may seize or flow due to frictional heat. become unable to do so. In addition, fluororesin,
In particular, although tetrafluoroethylene resin itself provides high heat resistance and excellent sliding properties, it has the disadvantage that it undergoes significant plastic deformation in a high load region and cannot provide stable sliding properties for a long period of time.
これらの欠点を改良する目的で、これらの合成樹脂に潤

くの問題があった。In order to improve these drawbacks, a method was adopted in which lubricating oil was added to these synthetic resins to make so-called oil-impregnated plastics. There were many problems, such as poor physical properties of the resulting molding material, and abnormal wear when the oil ran out.
一方、上述の液状の潤滑油に代わって、固体潤滑材を加

いは、熱可塑性樹脂に、酸化不融化処理したポリフェニ

−２７５６６７号公報）等があげられる。On the other hand, a method is already known in which a solid lubricant is added instead of the above-mentioned liquid lubricant to improve sliding characteristics. For example, a method in which polyphenylene sulfide contains tetrafluoroethylene resin, metal oxide powder, or aromatic polyamide fiber (Japanese Patent Application Laid-open No. 100123/1983);
A method of adding nickel powder and carbon fiber to an olefin-based synthetic resin (JP-A-61-168645), or a method of blending a thermoplastic resin with polyphenylene sulfide resin powder treated to make it infusible by oxidation (JP-A-63
-275667), etc.
かかる方法によって、上述の含油プラスチックにおける

しては不充分である。Although this method solves the above-mentioned problem caused by oil seepage in oil-impregnated plastics, the inclusion of metal or inorganic particles damages the sliding surface of the mating material, making it difficult to maintain stable sliding properties. I can't get it. In particular, in order to reduce the weight of equipment, the mating material may be resin or aluminum,
In the case of soft metals such as brass, it causes abnormal wear. Furthermore, although it is possible to improve the material properties of the resulting molded product by adding aromatic polyamide fibers or carbon fibers, it is difficult to disperse during molding, and fibrillar wear particles are generated during friction. This caused new problems such as accumulation. In addition, polyphenylene sulfide resin powder treated with oxidative infusibility treatment,
It does not have sufficient heat resistance, making it unsatisfactory as a sliding material for high-load, high-speed applications.
［発明が解決しようとする課題］

The object of the present invention is to provide a lubricating resin composition that has dynamic properties and excellent material properties.
