Title:
LUBRICANT AGENT COMPOSITION AND LUBRICANT OIL COMPOSITION CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2015/076103
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a lubricant oil additive composition which can exhibit a high friction-reducing effect even under a severe condition in which a high contact pressure is applied; and a lubricant oil composition in which the lubricant oil additive composition is contained to a base oil.
For achieving the purpose, the present invention provides: a lubricant agent composition comprising (A) a molybdenum dithiocarbamate that is represented by general formula (1) and (B) a copolymer that contains a unit (a) represented by general formula (2) and a unit (b) represented by general formula (3) as essential constituent units, has a weight average molecular weight of 5,000 to 150,000 and also has a composition ratio of the unit (a) to the unit (b), i.e., (a)/(b), of 50/50 to 90/10 by mole; and a lubricant agent composition in which the lubricant agent composition is contained in a base oil.
