Title (EN) LUBRICANT OIL COMPOSITION AND METHOD FOR MANUFACTURING SAME
(FR) COMPOSITION D’HUILE LUBRIFIANTE, ET PROCÉDÉ DE FABRICATION DE CELLE-CI
(JA) 潤滑油組成物及びその製造方法
Abstract:
(EN) Provided is a lubricant oil composition that has a low sulfate ash content but yet shows excellent cleanliness and maintains excellent friction reduction action even after deterioration. The lubricant oil composition comprises a base oil (A), a metal-free sulfur-based antioxidant (B) and a hindered amine-based antioxidant (C) having a piperidine derivative skeleton in a molecule, wherein: the content of the metal-free sulfur-based antioxidant (B) in terms of sulfur atoms is 800 mass ppm or more relative to the total lubricant oil composition; the content of the hindered amine-based antioxidant (C) in terms of nitrogen atoms is 100-400 mass ppm inclusive relative to the total lubricant oil composition; the sulfate ash content of the lubricant oil composition is 0.70 mass% or less; and the total base number of the lubricant oil composition is 4.0 mgKOH/g or more.
(FR) L’invention fournit une composition d’huile lubrifiante dont la propreté est satisfaisante indépendamment d’une faible quantité de cendre d’acide sulfurique, et qui présente un effet réducteur de friction y compris après dégradation. La composition d’huile lubrifiante de l’invention comprend : une huile de base (A) ; un inhibiteur d’oxydation à base de soufre exempt de métal (B) ; et un inhibiteur d’oxydation à base d’amine encombré (C) possédant un squelette de dérivé de pipéridine dans chaque molécule. La teneur en termes d’atomes de soufre dudit inhibiteur d’oxydation à base de soufre exempt de métal (B), est supérieure ou égale à 800ppm en masse sur la base de la quantité totale de ladite composition d’huile lubrifiante. La teneur en termes d’atomes d’azote dudit inhibiteur d’oxydation à base d’amine encombré (C), est supérieure ou égale à 100ppm en masse et inférieure ou égale à 400ppm en masse sur la base de la quantité totale de ladite composition d’huile lubrifiante. La cendre d’acide sulfurique de ladite composition d’huile lubrifiante, est inférieure ou égale à 0,70% en masse. L’indice de basicité de ladite composition d’huile lubrifiante est supérieur ou égal à 4,0mgKOH/g.
