Title (EN) AMINE TUNGSTATES AND LUBRICANT COMPOSITIONS
(FR) TUNGSTATES D'AMINE ET COMPOSITIONS DE GRAISSAGE
Abstract: front page image
(EN)This invention relates to lubricating oil additives, and to lubricating oil compositions, their method of preparation, and use. More specifically, this invention relates to several novel lubricating oil additives and compositions which contain a tungsten compound and an antioxidant, namely aminic antioxidants such as a secondary diarylamine or an alkylated phenothiazine. The use of the tungsten compound with the secondary diarylamine and/or the alkylated phenothiazine provides improved oxidation and deposit control to lubricating oil compositions. The lubricating oil compositions of this invention are particularly useful as crankcase and transmission lubricants, gear oils and other high performance lubricant applications.
(FR)L'invention concerne des additifs d'huile de graissage, des compositions d'huile de graissage, un procédé de préparation de ceux-ci ainsi que leur utilisation. Plus spécifiquement, l'invention concerne plusieurs nouveaux additifs et compositions d'huile de graissage qui contiennent un composé de tungstène et un antioxydant, à savoir des antioxydants aminés tels qu'une diarylamine secondaire ou une phénothiazine alkylée. L'utilisation du composé de tungstène avec la diarylamine secondaire et/ou la phénothiazine alkylée confère aux compositions d'huile de graissage une oxydation améliorée et une régulation améliorée de la formation de dépôts. Les compositions d'huile de graissage de l'invention sont particulièrement utiles comme lubrifiants de carter et de boîte de vitesses, huiles pour engrenages et d'autres applications de graissage hautes performances.
