Description
(1) 基油と、添加剤とを含有する潤滑油組成物であり、
添加剤として、脂肪族ポリスルフィドを潤滑油組成物中1〜10質量%含み、
かつ、脂肪族ポリスルフィド中の一級型脂肪族ポリスルフィドの割合が1〜50質量%である潤滑油組成物。
を提供するものである。
本発明の潤滑油組成物は、基油と、添加剤とを含有する潤滑油組成物であり、
添加剤として、脂肪族ポリスルフィドを潤滑油組成物中1〜10質量%含み、
かつ、脂肪族ポリスルフィド中の一級型脂肪族ポリスルフィドの割合が1〜50質量%である潤滑油組成物である。
本発明の潤滑油組成物は、基油を含む。基油としては、鉱油であってもよく、合成油であってもよい。
本発明の潤滑油組成物は、脂肪族ポリスルフィドを含有することを特徴とする。本発明の潤滑油組成物は、脂肪族ポリスルフィドを含まないと、所望の耐焼付性を満足することができないが、脂肪族ポリスルフィドの添加により金属腐食性が悪化する課題があった。特に、耐焼付性を向上させるため、脂肪族ポリスルフィド中の硫黄含有量を高めることで、ポリスルフィド中の硫黄鎖長を長くすることが良く行われる。これにより硫黄ラジカル放出量が高められるが、逆に低温でも硫黄ラジカルを発生しやすくなる結果、腐食性が悪化することがよく見られた。一方、脂肪族ポリスルフィドの耐熱安定性は硫黄の結合する炭素原子に結合する炭素原子の数にも大きく影響を受けることがわかっている。耐熱性は炭素原子が1つ結合した一級型がもっとも高く、3つ結合した三級型が最も低い。硫黄ラジカル放出量もこれに応じた形で増減するため、硫黄含有量に加え、硫黄が結合した炭素の構造を適切な範囲内に調整することで、硫黄ラジカル放出量を適切に調整できることを見出した。―級型ポリスルフィドは高耐熱であるため、混合物とした際に各々の性能の和から想定される性能を超えた変化が見られ、例えばわずかな配合量でも大きく耐焼付性を向上できた。
本発明の潤滑油組成物は、本発明の効果を損なわない範囲で、必要に応じて、さらに一般的に用いられるその他添加剤を含有してもよい。
本発明の潤滑油組成物の製造方法としては、特に制限は無く、例えば、基油に、上述の脂肪族ポリスルフィドを配合する工程を有する方法が挙げられる。
本発明の潤滑油組成物の100℃動粘度は、1.5mm2/s以上が好ましく、5mm2/s以上がより好ましく、50mm2/s以上が更に好ましい。また上限は、30mm2/s以下が好ましく、20mm2/s以下が更に好ましい。動粘度が上記範囲内であると、変速機用潤滑油組成物としてより適正なものとなり、耐焼付性及び耐銅腐食性が向上する。
以上説明してきたように、本発明の潤滑油組成物は、耐焼付性及び耐銅腐食性に優れるものであり、ガソリン自動車、ハイブリッド自動車、電気自動車等の自動車用変速機、建設又は農業、土木工作機械用変速機や工業用機械駆動部の潤滑に好適に用いられる。本発明の駆動部用潤滑油組成物は、優れた耐銅腐食性を有することから、電動モーター及び発電機等の電気部品を備えるハイブリッド自動車、電気自動車により好適に用いられ、該電動モーターの冷却が油冷却方式であるハイブリッド自動車、電気自動車等の変速機に、特に好適に用いられる。なお、変速機は、手動変速機、自動変速機、無段変速機のいずれであってもよい。本発明の潤滑油組成物は変速機等の機械駆動部用ではあるが、機械駆動部以外の用途、例えば、ガソリンエンジン、ディーゼルエンジン、その他内燃機関、自動車用ギヤ、その他一般機械等の工業用ギヤ、油圧機械、タービン、圧縮機、工作機械、切削機械等の体軸受け、転がり軸受けを備える機械等に用いてもよい。
表1に示す配合処方(質量%)で潤滑油組成物を調製した。それぞれの添加剤や基油に関して添加順や添加方法に特に制限はないが、基油に対して各添加剤を配合していく方法法でも、あらかじめ添加剤配合物を調製し、これを基油に添加する方法でも良い。特に添加剤配合物をあらかじめ調製する場合はリン化合物の配合を最後とすることが副反応の抑制の点から好ましい。得られた潤滑油組成物について、以下の方法により各種試験を行い、その物性を評価した。評価結果を表1に示す。
