Abstract
Description
粘度工剤は、多機能粘度調整剤として追加の機能を有してもよい。また、粘度指数向上剤が1種以上存在していてもよい。
サンプル潤滑油配合物は、ベースストックの混合物を含む基油を提供し、それに少なくとも耐摩耗剤および希釈剤中の他の添加剤を含む添加剤組成物(希釈剤はベースストックの1つである)を配合することによって調製した。製剤を以下の表2に要約する。
次いで、試料S1〜S6を耐摩耗性能およびエラストマー適合性試験に供した。特に、耐摩耗性のためのFZGおよびFE8ステップ1およびステップ2試験、ならびに上記のようなNBRおよびFKMエラストマー試験を行う。試験後の油を目視でスラッジをチェックし、レーザ顕微鏡で表面仕上げ試験を行った。試料S1〜S6についての試験結果を以下の表3に示す。
