Title (EN) LUBRICANT ADDITIVE PACKAGES FOR IMPROVING LOAD-CARRYING CAPACITY AND SURFACE FATIGUE LIFE
(FR) COMBINAISONS D'ADDITIFS DE LUBRIFIANT PERMETTANT D'AMELIORER LA CAPACITE DE CHARGE ET LA DUREE DE VIE EN FATIGUE DES SURFACES
Abstract: front page image
(EN)The present invention provides a multifunctional lubricant additive package or composition for improving load-carrying capacity, pressure resistance, surface fatigue life, and other performance characteristics of a lubricant or base oil. The composition typically includes four components: (a) an alkyl or aryl neutral phosphate, (b) a long-chain organic partial ester, (c) an aryl or alkyl phosphite, and (d) a phenol compound. The present invention further provides a multifunctional lubricant having improved performance characteristics, which are obtained by mixing a lubricant with the above-described multifunctional lubricant additive package or composition.
(FR)L'invention concerne une combinaison ou une composition d'additifs de lubrifiant multifonctionnels permettant d'améliorer la capacité de charge, la résistance à la pression, la durée de vie en fatigue, et d'autres caractéristiques de performance d'un lubrifiant ou d'une huile de base. Cette composition comprend normalement quatre composants: (a) un phosphate neutre d'alkyle ou d'aryle, (b) un ester partiel organique à chaîne longue, (c) un phosphite d'aryle ou d'alkyle, et (d) un groupe phénol. L'invention concerne en outre un lubrifiant multifonctionnel présentant des caractéristiques de performance améliorées, que l'on obtient en mélangeant le lubrifiant avec la combinaison ou la composition d'additifs multifonctionnels de lubrifiant décrites ci-dessus.
