Description
・100℃での動粘度が8.2〜12.6mm2/sで且つ飽和炭化水素分が90質量%以上である基油(A)に、
・金属系清浄剤(B)と、
・ジチオリン酸亜鉛(C)と
を配合してなり、
・前記金属系清浄剤(B)を組成物100g当たり石鹸分含有濃度として2.5mmol以上含有し、
・リン分が200〜1000質量ppmであり、
・塩基価が7.5mgKOH/g以上である
ことを特徴とする。
金属系清浄剤の石鹸分含有濃度(mmol/100g)
=10×Σ{(金属系清浄剤配合量[質量%]×金属系清浄剤中の金属含有量[質量%])/(金属比×金属原子量)}
金属比=全金属分/石鹸分子に起因する金属分の質量比
(D−1)炭素数40〜400のアルキル基又はアルケニル基を分子中に少なくとも1個有するコハク酸イミド、あるいはその誘導体、
(D−2)炭素数40〜400のアルキル基又はアルケニル基を分子中に少なくとも1個有するベンジルアミン、あるいはその誘導体、
(D−3)炭素数40〜400のアルキル基又はアルケニル基を分子中に少なくとも1個有するポリアミン、あるいはその誘導体。

表1〜2に示す配合処方の潤滑油組成物を調製し、JPI−5S−55−99に準拠してホットチューブ試験及びASTM D2619を修正した加水分解試験を実施した。結果を表1〜2に示す。なお、表1〜2中、基油の量は、基油全量基準での含有量であり、一方、添加剤の量は、組成物全量基準での含有量である。
各試験油90質量%とシリンダー油のドリップ油10質量%との混合油を用いて、JPI−5S−55−99に準拠して、270℃、280℃及び290℃でホットチューブ試験を実施しし、試験後のテストチューブ変色部の色相の濃さの評点[0点(黒色)から10点(透明=最良)の間]で評価した。評点が高いほど、高温清浄性に優れることを示す。また、表2中、「閉塞」は、ガラス管が閉塞し、耐コーキング性が悪いことを示す。
試料(供試油100g/蒸留水10g)をコーク瓶に充填し、93℃の恒温槽内で5rpmで回転させることにより撹拌し、24時間後の試料に対して40000Gで1時間遠心分離を行い、水エマルションを分離し、上澄み油の塩基価を測定した。塩基価が高い程、加水分解安定性に優れることを示す。
