Abstract
【解決手段】(a)主要量の潤滑粘度の油;(b)カルボン酸のアニオンを含む少なくとも一つの配位子を含む一種以上のハロゲン不含油溶性チタン錯体;(c)一種以上の分散剤;および(d)一種以上の清浄剤を含み、いかなるジアルキルジチオリン酸亜鉛も含まない潤滑油組成物。
【選択図】なし
Description
用語「全塩基価」もしくは「TBN」は、1グラムの生成物を中和するために必要なミリグラム単位のKOHの当量数を意味する。従って、高いTBNは、強い過塩基性の生成物および、その結果として酸を中和するためにより高い塩基性が確保されていることを反映している。生成物のTBNは、ASTMに規定されたD2896もしくは同等の操作により測定できる。より高いTBNを有する潤滑剤は、低TBNの潤滑剤よりも大きなアルカリ性を示す。言い換えると、前者はより多量の酸性種を中和することができる。
基準となる自動車のエンジン油を、ジアルキルジチオリン酸亜鉛なしで、おおよそ80質量%のシェブロン220Nとシェブロン600Nとの7:1混合物からなるII種基油、8.1質量%のポリイソブチレンコハク酸イミド分散剤の油濃縮物の混合物、2.2質量%の高および低BNを有する清浄剤の油濃縮物の混合物、モリブデン抑制剤、アミン系およびフェノール系の酸化防止剤の混合物、エチレン−プロピレンコポリマー粘度指数向上剤、および消泡剤を含むように生成した。以下の実施例において、チタン化合物は、最終潤滑油中に、おおよそ1600ppmとなるTiの量で加えた。
基準となる潤滑油の処方を、比較例Aと同じ添加剤、基油、および処理比を含むように生成した。下記の方法で製造したチタンジオレエート・イソプロポキシドを、上記の基準となる潤滑油の処方に対して2.4質量%で処方した。
基準となる潤滑油の処方を、比較例Aと同じ添加剤、基油、および処理比を含むように生成した。実施例1に開示した手順と類似の方法で製造したトリイソステアリル・イソプロポキシドチタン(IV)錯体を、上記の基準となる潤滑油の処方に対して3.1質量%で処方した。
基準となる潤滑油の処方を、比較例Aと同じ添加剤、基油、および処理比を含むように生成した。チタン(IV)イソプロポキシドを、上記の基準となる潤滑油の処方に対して1質量%で処方した。
基準となる潤滑油の処方を、比較例Aと同じ添加剤、基油、および処理比を含むように生成した。二級ZnDTPを、上記の基準となる潤滑油の処方に対して19ミリモルZn/kg潤滑油で処方した。
実施例1および2の潤滑油組成物と比較例A〜Cの潤滑油組成物との摩耗防止性能を、「ディーゼルエンジン内のすすによる摩耗」E.S.ヤマグチ、M.ウンターマン、S.H.ロビー、P.R.リアソン、およびS.W.イーのジャーナル・オブ・エンジニアリング・トライボロジー220(J5)、2006年8月によりシェブロン社が変更したPCS MTMベンチテストを用いて評価した。この試験では、エンジンのすすを加えた試験油で潤滑している回転中の金属ディスクを、固定した金属ボールに擦り付けた。摩耗による傷が、固定した金属ボール上に生じる。摩耗による傷の直径を測定し、記録する。摩耗による傷が低レベルであることは、優れた摩耗防止性能を有する油を示すと見ることができる。
