アミド樹脂組成物およびかかる組成物よりなる摺動部材
に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a polyamide resin composition for a sliding member that requires flexibility and sound-dampening properties, and a sliding member made of such a composition.
（従来の技術）
柔軟性と消音性が要求される摺動部材の代表として消音

材の弾性率として通常１０００〜５０００ｋｇｆ／ｃ−
程度の材料が使用されている。(Prior Art) A noise-reducing gear is a representative example of a sliding member that requires flexibility and noise-reducing properties. The characteristics required for gear materials built into OA machines and precision equipment are low noise and high sliding properties. The noise prevention effect is related to the elastic modulus of the material, and materials with a low elastic modulus have a sound dampening effect. However, since torque is applied to gears, considering the strength, the elastic modulus of gear materials is usually 1000 to 5000 kgf/c-
materials are used.

テトラメチレングリコール等で共重合化したポリアミド
エラストマーが多く用いられる。Among polyamides, polyamide elastomers copolymerized with nylon 12 containing a plasticizer, polytetramethylene glycol, etc. are often used.
さらにその摩擦、摩耗特性といった摺動性を向上させる
ため、潤滑剤を添加するのが普通である。Furthermore, in order to improve sliding properties such as friction and wear characteristics, a lubricant is usually added.
潤滑剤にはオイル、核剤、二硫化モリブデン、テフロン

いる。Well-known lubricants include oil, nucleating agents, molybdenum disulfide, Teflon powder, and lubricants. Furthermore, since the sliding properties of high-density polyethylene are excellent, a proposal (Japanese Patent Publication No. 46-41456) has been made to mix powder thereof.
（発明が解決しようとする課題）
しかしながら、含油処方は成形時にペレットがら油分の
しみ出しが生じてスリッピングを起こしやすく、二硫化
モリブデンの添加は摩擦係数を下げる効果が十分ではな
い。テフロンパウダーの添加は耐摩耗性に欠ける。しか
も、これら代表的潤滑剤の配合は、機械的強度を低下す
る欠点があるほかコストアップにつながることにもなる
。高密度ポリエチレンを混合する方法は、溶融粘度か大
きいため分散性が悪く、均一な材料か得にくい欠点かあ
る。(Problems to be Solved by the Invention) However, oil-containing formulations tend to cause oil to seep out of the pellets during molding and cause slipping, and the addition of molybdenum disulfide does not have a sufficient effect of lowering the coefficient of friction. Addition of Teflon powder lacks wear resistance. Moreover, the combination of these typical lubricants has the disadvantage of lowering mechanical strength and also leads to increased costs. The method of mixing high-density polyethylene has the disadvantage of poor dispersibility due to its high melt viscosity, making it difficult to obtain a uniform material.
このように摺動部材、特に柔軟性と消音性か要求される
消音ギヤーなどの摺動部材に要求される特性は、機械的

いが、従来満足すべきものがなかった。そこで発明者は
これらの要件を満たす摺動部材用樹脂組成物を提供する
ため、鋭意研究の結果本発明に到達したものである。In this way, the characteristics required for sliding members, especially for sliding members such as noise-reducing gears that require flexibility and sound-dampening properties, are low friction coefficient and wear resistance without compromising mechanical strength and elongation. It must have excellent properties and be easy to mold, but so far there has been no satisfactory product. Therefore, in order to provide a resin composition for sliding members that satisfies these requirements, the inventors conducted extensive research and arrived at the present invention.

れている。The polyamide/polyolefin graft copolymer used in the present invention is a copolymer obtained by graft-polymerizing a polyamide to a polyolefin having an acidic functional group. Examples of the polyolefin copolymer having an acidic functional group serving as a skeleton include methacrylic acid/ethylene copolymer, acrylic acid/ethylene copolymer, and the like. Methods for grafting polyamides include melt polymerizing polyamide monomers such as caprolactam and lauryllactam together with a small amount of phosphoric acid at normal pressure, or grafting polyamide oligomer within a limited degree of polymerization to a backbone polyolefin. There is a method of reacting to form a copolymer. Regarding the manufacturing method of these graft copolymers, for example, JP-A No. 5
