本発明は、摺動材用樹脂組成物に関する。更に詳しくは
、低コスト化された摺動材用樹脂組成物に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a resin composition for sliding materials. More specifically, the present invention relates to a resin composition for sliding materials that is lower in cost.
ポリアミド６、ポリアミド６−６、ポリアミド４−６゜
ポリアミド１１．ポリアミド１２などのポリアミド樹脂
は、樹脂材料の中では自己潤滑性に富む樹脂であるが、
各種機器などの性能向上に対応するため、なお−層の潤
滑性の向上が要求されている。Polyamide 6, Polyamide 6-6, Polyamide 4-6° Polyamide 11. Among resin materials, polyamide resins such as polyamide 12 are highly self-lubricating.
In order to respond to improvements in the performance of various types of equipment, improvements in the lubricity of the layer are required.

れ、用いられている。In response to such demands, tetrafluoroethylene resin-filled polyamide resins, molybdenum disulfide-filled polyamide resins, carbon fiber-filled polyamide resins, and the like have been commercially available and used.
しかしながら、テトラフルオロエチレン樹脂充填ポリア

干すぐれてはいるものの、それ程大きな効果はみられな
い。However, although the tetrafluoroethylene resin-filled polyamide resin is effective in terms of the coefficient of friction, it has almost no effect on wear, and furthermore, it has the disadvantage of greatly reducing strength. Although molybdenum disulfide-filled polyamide resin is slightly superior to unfilled polyamide resin in terms of sliding properties, the effect is not that great.

それは高価であるという欠点を有する。Under these circumstances, carbon fiber-filled polyamide resin has been used as a material that has excellent friction and wear properties even under severe conditions, but it has the disadvantage of being expensive due to the filler.
そこで、本発明者らは、カーボン繊維充填ポリアミド樹

擦摩耗特性の低下を抑制し、前記課題を解決することに
成功した。Therefore, the present inventors conducted various studies in search of an inexpensive filler-filled polyamide resin that has friction and wear characteristics comparable to those of carbon fiber-filled polyamide resin. However, filling with glass fiber alone will actually reduce the friction and wear properties, so by adding both tetrafluoroethylene resin and molybdenum disulfide to form a composite, the reduction in the friction and wear properties can be suppressed. succeeded in solving the problem.
従って１本発明は摺動材用樹脂組成物に係り、この樹脂
組成物は、ポリアミド樹脂、ガラス繊維、テトラフルオ
ロエチレン樹脂および二硫化モリブデンよりなる。Accordingly, the present invention relates to a resin composition for sliding materials, and this resin composition comprises a polyamide resin, glass fiber, a tetrafluoroethylene resin, and molybdenum disulfide.
ガラス繊維としては、一般に繊維径約３〜１３μｍ。Glass fibers generally have a fiber diameter of about 3 to 13 μm.
繊維長約１〜１０ｍｍのものなどが用いられ、テトラフ
ルオロエチレン樹脂としては、一般に溶融粘度が１０１
０〜１０１３ポイズのものが用いられ、また二硫化モリ
ブデンとしては粒径が約１〜１０μｍのものなどが用い
られる。Those with a fiber length of about 1 to 10 mm are used, and tetrafluoroethylene resins generally have a melt viscosity of 101 mm.
Molybdenum disulfide having a particle size of about 1 to 10 μm is used.
これらの充填材は、組成物中ガラス繊維が約３〜２０重
量％、好ましくは約５〜１５重量２の割合で、テトラフ
ルオロエチレン樹脂がやはり約３〜２０重ｉ％、好まし
くは約５〜１５重量％の割合で、また二硫化モリブデン
が約１〜５重量％、好ましくは約２〜３重、ｌＸｔ％の
割合で用いられる。These fillers include about 3 to 20% by weight of glass fibers, preferably about 5 to 15% by weight of the composition, and about 3 to 20% by weight of tetrafluoroethylene resin, preferably about 5 to 1% by weight of tetrafluoroethylene resin. Molybdenum disulfide is used in a proportion of 15% by weight, and molybdenum disulfide in a proportion of about 1-5% by weight, preferably about 2-3% by weight, 1Xt%.
このような充填割合が選択されるのは、次のような理由
に基いている。即ち、これ以上の割合で用いられると、
ガラス繊維では摺動特性を悪化させ、テトラフルオロエ
チレン樹脂および二硫化モリブデンについては強度低下
がみられ、一方各成分がこれ以下の割合で用いられると
本発明の目的を達成することができない。The reason why such a filling ratio is selected is as follows. In other words, if it is used at a rate higher than this,
Glass fiber deteriorates the sliding properties, and tetrafluoroethylene resin and molybdenum disulfide cause a decrease in strength. On the other hand, if each component is used in a lower proportion than this, the object of the present invention cannot be achieved.

れる。The polyamide resin composition according to the present invention uses glass fibers instead of carbon fibers, and compensates for the lack of friction and wear characteristics by using a combination of tetrafluoroethylene resin and molybdenum disulfide. It comes to exhibit properties comparable to filled polyamide resin. Therefore, this composition can be effectively used as a molding material for sliding materials such as bearings, gears, and chain guides.
