４ ）。PRIOR ART Conventionally, a grease composition using a combination of an oil-insoluble phosphorus compound and an oil-soluble sulfur compound as a layer for improving the extreme pressure characteristics of a lubricating grease composition has been known (Japanese Patent Laid-Open No. 54-3430).
4).
しかしながら、油不溶性リン酸化合物単独を使用した場
合には所望の極圧性の向上は達成されなかった。However, when the oil-insoluble phosphoric acid compound was used alone, the desired improvement in extreme pressure properties was not achieved.
従来、滴点が高く、耐熱性くすぐれしかも常温から高温

潤滑用グリース組成物が要望されていた。Conventionally, there has been a demand for a lubricating grease composition that has a high dropping point, excellent heat resistance, and has excellent mechanical stability, load carrying capacity, and wear resistance when exposed to temperatures ranging from room temperature to high temperatures.
本発明は一鉱油または合成潤滑油にリン酸三カルシウム
を配合したグリース組成物がきわめてすぐれた性質を有
することを見出したことにもとづくものである。The present invention is based on the discovery that a grease composition containing tricalcium phosphate in mineral oil or synthetic lubricating oil has extremely excellent properties.
すなわち、本発明は、
弐〇ａ、（ＰＯ４）、で表わされるリン酸三カルシウム

ある。That is, the present invention relates to a grease composition characterized by containing 2 to 40% by weight of tricalcium phosphate represented by 20a, (PO4) based on mineral oil or synthetic lubricating oil. .
本発明によるリン酸三カルシウムグリースは高滴点をも

、耐荷重性にもきわめてすぐれているものである。The tricalcium phosphate grease according to the present invention has a high dropping point, excellent oxidation stability at high temperatures, and at the same time extremely excellent wear resistance and load carrying capacity.
また、鉱油及び各種の合成油に対し、親和性に富み、グ
リースが容易に製造できること、価格が安いことなど多
くの利点を有している。It also has many advantages, such as high affinity for mineral oils and various synthetic oils, easy production of grease, and low cost.
本発明のグリースに用いる基油としては、通常の潤滑油
の粘度範囲（１００℃、２〜４０ｃｓｔ）のものであれ
ばすべて使用できる。As the base oil used in the grease of the present invention, any base oil can be used as long as it has a viscosity within the range of normal lubricating oils (100° C., 2 to 40 cst).
例えば、ナフテン−基、パラフィン基及び混合基油等鉱
物潤滑油、α−オレフィンポリマー系合成油、セバシン
酸ジオクチルの如き二塩基酸のジエステル、トリメチロ

ステル、シリコーン油、ポリエーテル系合成油等があげ
られる。For example, mineral lubricating oils such as naphthenic, paraffinic and mixed base oils, α-olefin polymer synthetic oils, diesters of dibasic acids such as dioctyl sebacate, polyol esters such as trimethylolpropane and pentaerythritol, silicone oils, Examples include polyether-based synthetic oils.
リン酸三カルシウムをグリースの増粘剤として使用する
場合には、潤滑油中に２ないし４０重量％、好ましくは
５ないし３０！量％、さらに好ましくは、１０ないし２
５重量％で使用する。When tricalcium phosphate is used as a grease thickener, it is present in the lubricating oil in an amount of 2 to 40% by weight, preferably 5 to 30%! amount%, more preferably 10 to 2
Used at 5% by weight.
リン酸三カルシウムの配合量が２重量外以下の場合には
、滴点の上昇および例えばせん断安定性、耐荷重性、耐
摩耗性などの機械的安定性の改良の効果が得られない。If the amount of tricalcium phosphate is less than 2% by weight, the effects of increasing the dropping point and improving mechanical stability such as shear stability, load resistance, and abrasion resistance cannot be obtained.
′また、４０ｉｉ％以上の場合には粘１’４ Ｋなりす
ぎて使用が困篠である。'Furthermore, if it is more than 40%, the viscosity becomes too high, making it difficult to use.

易に適合する。In addition, it has excellent oxidation stability and load resistance even without antioxidants or extreme pressure agents, but it can also be used with various additives normally used in greases, such as antioxidants, extreme pressure agents, rust preventives, and adhesives. Easy to fit.

添加すればよい。In order to more efficiently disperse tricalcium phosphate into the base oil, it is necessary to pre-treat the surface with a surfactant such as alkyltrimethylammonium chloride or polyoxyethylene dobutylamine, or use these surfactants. Just add a small amount.

。In addition, a dispersant such as bentone grease, amethane, propylene carbonate, etc. may be used. When the base oil is processed in a three-roll mill or a colloid mill, without using a dispersant, and in the necessary amount to adjust its consistency, it forms a smooth grease.
