Abstract
(EN)
[Problem] To provide a lubricant oil composition which is for a compressor oil, and which has not only extremely favorable temperature viscosity properties but also good heat-resistant oxidation stability. [Solution] This lubricant oil composition for a compressor oil has a kinematic viscosity at 40 °C of 10-300 mm2/s, and contains: 10-99 mass% of a lubricant base oil (A) having a kinematic viscosity at 100 °C of 1-14 mm2/s, a viscosity index of 100 or more, and a pour point of 0 °C or less; 1-90 mass% of a liquid-phase random copolymer ethylene-α-olefin copolymer (B) formed of ethylene and α-olefin and prepared by using a specific catalyst (the sum of (A) and (B) is 100 mass%).

L'invention fournit une composition d'huile lubrifiante pour huile de compresseur qui possède des caractéristiques de température et viscosité tout à fait excellentes, et qui se révèle également excellente en termes de résistance à la chaleur et stabilité à l'oxydation. Plus précisément, l'invention concerne une composition d'huile lubrifiante pour huile de compresseur qui comprend 10 à 99% en masse d'une huile de base d'huile lubrifiante (A) de viscosité cinématique à 100°C comprise entre 1 et 14mm2/s, d'indice de viscosité supérieur ou égal à 100 et de point d'écoulement inférieur ou égal à 0℃, et 90 à 1% en masse d'un copolymère éthylène - α-oléfine (B), copolymère aléatoire liquide d'un éthylène et d'une α-oléfine fabriqué à l'aide d'un catalyseur spécifique (Le total de (A) et (B) valant 100% en masse.), et qui présente une viscosité cinématique à 40°C comprise entre 10 et 300mm2/s.
