Title (EN) LUBRICANT COMPOSITION
(FR) COMPOSITION D'HUILE LUBRIFIANTE
(JA) 潤滑油組成物
Abstract:
(EN) A lubricant composition which contains a lubricant base oil, (A) a dispersed poly(meth)acrylate compound having a weight average molecular weight of 30,000 to 200,000 in an amount of 1-10% by mass based on the total amount of the composition, and (B) a non-dispersed poly(meth)acrylate compound having a weight average molecular weight of 15,000 to 100,000 in an amount of 15% by mass or less based on the total amount of the composition, and wherein: the ratio of the content MA of the component (A) to the content MB of the component (B), namely, MA/MB is 0.05 to 1; and the ratio of the weight average molecular weight MwB of the component (B) to the weight average molecular weight MwA of the component (A), namely, MwB/MwA is 0.05 to 2.
(FR) L’invention concerne une composition d’huile lubrifiante qui comprend une huile de base d’huile lubrifiante, (A) 1 à 10% en masse de l’ensemble de la composition d’un composé de poly(méth)acrylate de type dispersé de masse moléculaire moyenne en poids compris entre 30000 et 200000, et (B) 15% en masse ou moins de l’ensemble de la composition d’un composé de poly(méth)acrylate de type non dispersé de masse moléculaire moyenne en poids compris entre 15000 et 100000. Le rapport (MA/MB) entre la teneur (MA) en composant (A) et la teneur (MB) en composant (B), est compris entre 0,05 et 1. Le rapport (MwB/MwA) de masse moléculaire moyenne en poids (MwB) du composant (B) par rapport à la masse moléculaire moyenne en poids (MwA) du composant (A), est compris entre 0,05 et 2.
