Abstract
(EN)
The present invention provides a lubricating oil composition containing a polymer for improving viscosity, the polymer having little decrease in viscosity due to shear, keeping viscosity elevation at low temperatures low, and having exceptional low-temperature characteristics. The present invention is a lubricating oil composition characterized by containing: 30-90 wt% of a liquid random copolymer (A) of ethylene and an α-olefin, the copolymer being produced by through specific method; and 10-70 wt% of a lubricating oil base comprising one or more components selected from specific synthetic oils (B) or mineral oils (C) (where the total of components (A), (B), and (C) is 100 wt%).
(FR)
L'invention fournit une composition d'huile lubrifiante qui est telle qu'une baisse d'élévation de viscosité lorsque la température est basse est limitée, et qui contient un polymère pour amélioration de viscosité doté d'excellentes caractéristiques à basse température et présentant une faible diminution de viscosité due au cisaillement. Plus précisément, l'invention concerne une composition d'huile lubrifiante qui est caractéristique en ce qu'elle comprend 30 à 90% en masse d'un copolymère aléatoire liquide (A) d'un éthylène et d'une α-oléfine fabriqué selon un procédé spécifique, et 10 à 70% en masse d'un agent d'huile de base d'huile lubrifiante constitué d'au moins une sorte de composant choisie parmi une huile synthétique spécifique (B) ou une huile minérale (C) (le total des composants (A), (B) et (C) valant 100% en masse).
