Description
本発明は、グリース組成物に関し、詳しくは、樹脂部材同士または、樹脂部材と金属部材との摺動部分に用いるグリース組成物において、潤滑機能（動摩擦係数が低いこと）と共に静止機能（静摩擦係数が高いこと）を併せ持つ潤滑グリース組成物に関する。 The present invention relates to a grease composition, and more specifically, in a grease composition used for sliding parts between resin members or between a resin member and a metal member, a static function (static friction coefficient is low) together with a lubrication function (low dynamic friction coefficient). High lubricity grease).
従来から歯車、および摺動部に使用される潤滑剤組成物としてグリースが使用されているが、近年の自動車部品、家電製品、電子情報機器、ＯＡ機器などでは軽量化、低コスト化を目的として歯車、および摺動部に樹脂部材が使用されることが多くなってきている。また近年、自動車やＯＡ機器の減速装置内の減速ギア部等において、静止時のすべり防止のため高い静摩擦係数が必要とされている。このような樹脂部材同士または、樹脂部材と金属部材との摺動部分に使用されるグリースには、潤滑機能（動摩擦係数が低いこと）と共に静止機能（静摩擦係数が高いこと）を併せ持つことが求められている。 Conventionally, grease has been used as a lubricant composition used for gears and sliding parts, but in recent automobile parts, home appliances, electronic information equipment, OA equipment, etc., for the purpose of reducing weight and cost. Resin members are increasingly used for gears and sliding parts. Further, in recent years, a high static friction coefficient is required in a reduction gear portion in a reduction device of an automobile or OA equipment in order to prevent slipping at rest. The grease used for the sliding parts between such resin members or between the resin member and the metal member is required to have both a lubricating function (low coefficient of dynamic friction) and a static function (high coefficient of static friction). It has been.
例えば、特許文献１で樹脂製摺動部材同士または、樹脂製摺動部材と金属製摺動部材との間の摩擦係数を低減するグリース組成物が開示されている。 For example, Patent Document 1 discloses a grease composition that reduces a friction coefficient between resin sliding members or between a resin sliding member and a metal sliding member.
特許文献２は固体潤滑剤としてメラミン樹脂、シリコーン樹脂、パラフィンワックスおよびフッ素樹脂を開示している。
しかし、特許文献１に記載の技術では、静止機能の部分では十分な機能を有していないという問題がある。 However, the technique described in Patent Document 1 has a problem that the static function portion does not have a sufficient function.
また、特許文献２には、固体潤滑剤としてメラミン樹脂が記載されているが、メラミンシアヌレート（ＭＣＡ）についての記載がない。 Patent Document 2 describes a melamine resin as a solid lubricant, but does not describe melamine cyanurate (MCA).
そこで、本発明は、上記従来技術の問題を解決するものであり、本発明の課題は、樹脂部材同士または、樹脂部材と金属部材との摺動部分に用いるグリース組成物において、潤滑機能（動摩擦係数が低いこと）と共に静止機能（静摩擦係数が高いこと）を併せ持つ潤滑グリース組成物を提供することにある。 Therefore, the present invention solves the above-described problems of the prior art, and an object of the present invention is to provide a lubricating function (dynamic friction) in a grease composition used for sliding portions between resin members or between a resin member and a metal member. Another object is to provide a lubricating grease composition having a low coefficient) and a static function (high coefficient of static friction).
また本発明の他の課題は、以下の記載により明らかになる。 Other problems of the present invention will become clear from the following description.

本発明において、固体潤滑剤は、ＭＣＡとＰＴＦＥを併用し、その配合比率および配合量を特定の範囲とすることで、潤滑機能（低動摩擦係数）と共に静止機能（高静摩擦係数）を併せ持つことが可能となる。 In the present invention, the solid lubricant may have both a lubricating function (low dynamic friction coefficient) and a static function (high static friction coefficient) by using MCA and PTFE in combination and setting the blending ratio and blending amount within a specific range. It becomes possible.
ＭＣＡとＰＴＦＥの配合比率は、ＭＣＡ／ＰＴＦＥ（重量比）＝０．０５〜５０の範囲であり、好ましくは ０．１〜２０の範囲である。 The mixing ratio of MCA and PTFE is MCA / PTFE (weight ratio) = 0.05 to 50, preferably 0.1 to 20.
０．０５未満であると、静摩擦係数が低くなってしまい、必要な静止機能が得られず、５０以上であると静摩擦係数が高くなるが、動摩擦係数も高くなってしまい、必要な潤滑機能が得られない。 If it is less than 0.05, the static friction coefficient becomes low and the necessary static function cannot be obtained, and if it is 50 or more, the static friction coefficient becomes high, but the dynamic friction coefficient also becomes high and the necessary lubrication function is obtained. I can't get it.

It is a range.
０．１ｗｔ％未満であると、静摩擦係数が低くなってしまい、必要な静止機能が得られない。また固体潤滑剤の機能を発揮しない。２５ｗｔ％より多いと、グリース組成物が硬くなりすぎるため、動摩擦係数が高くなってしまい、必要な潤滑機能が得られない。 If it is less than 0.1 wt%, the static friction coefficient becomes low, and a necessary static function cannot be obtained. Also, it does not exhibit the function of a solid lubricant. If it is more than 25 wt%, the grease composition becomes too hard, so that the dynamic friction coefficient becomes high and a necessary lubricating function cannot be obtained.
ＭＣＡはメラミンとイソシアヌル酸の付加物であることから、特開平１１−３３２１７７号公報に記載のメラミン樹脂とは異なる。 Since MCA is an adduct of melamine and isocyanuric acid, it differs from the melamine resin described in JP-A-11-332177.
