| abstract |
An object of the present invention is to provide a low-foaming metalworking lubricant excellent in lubricity such as abrasion resistance and the like, and excellent in separating oil such as mixed sliding surface oil. A polyether (A) which is an alkylene oxide adduct of an aliphatic alcohol having a specific structure and has a HLB of 8.5 or more and a weight average molecular weight of 1,000 to 10,000, and a derivative thereof. , And an aliphatic monocarboxylic acid and / or dicarboxylic acid having 8 to 12 carbon atoms and / or dicarboxylic acid (B), wherein the mixing ratio is (A) 100 parts by weight and (B) is 1 to 400 parts by weight for metal working. It is a lubricant. [Selection diagram] None |
