Description

本発明で使用されるβ−ジチオフォスホリル化プロピオン酸の添加量は潤滑油基油１００重量部に対し０．００５〜０．５重量部、好ましくは０．００５〜０．２重量部、とくに好ましくは０．０１〜０．１重量部である。添加量が０．００５重量部未満では十分な効果が得られず、０．５重量部を越えても潤滑性能が飽和し、熱酸化安定性、加水分解安定性、腐食性を低下させるので好ましくない。なお、下記一般式（２）のりん酸トリアリールとの組み合わせの場合におけるβ−ジチオフォスホリル化プロピオン酸の添加量は潤滑油基油１００重量部に対し０．００１〜０．１重量部、好ましくは０．００５〜０．０５重量部である。 The amount of β-dithiophosphorylated propionic acid used in the present invention is 0.005 to 0.5 parts by weight, preferably 0.005 to 0.2 parts by weight, based on 100 parts by weight of the lubricating oil base oil. Particularly preferably, it is 0.01 to 0.1 parts by weight. If the addition amount is less than 0.005 parts by weight, a sufficient effect cannot be obtained, and even if it exceeds 0.5 parts by weight, the lubrication performance is saturated and the thermal oxidation stability, hydrolysis stability and corrosiveness are lowered, which is preferable. Absent. The amount of β-dithiophosphorylated propionic acid added in combination with triaryl phosphate of the following general formula (2) is 0.001 to 0.1 parts by weight with respect to 100 parts by weight of the lubricating oil base oil. , Preferably 0.005 to 0.05 parts by weight.

本発明では前記の必須成分のほかに更に性能を向上させるため、必要に応じて通常使用される種々の追加的添加剤が適宜使用できる。これらには、酸化防止剤、防錆剤、金属不活性剤、清浄分散剤、耐摩耗剤、極圧剤、摩擦調整剤、流動点降下剤、粘度指数向上剤、抗乳化剤、消泡剤等の公知の潤滑油添加剤を挙げることができる。 In the present invention, in addition to the above-mentioned essential components, various additional additives usually used as necessary can be appropriately used in order to further improve the performance. These include antioxidants, rust inhibitors, metal deactivators, cleaning dispersants, abrasion resistant agents, extreme pressure agents, friction modifiers, pour point lowering agents, viscosity index improvers, anti-emulsifiers, defoamers, etc. Known lubricating oil additives can be mentioned.
