PURPOSE:To obtain the titled compsn. which can maintain high lubricating and rolling performances for a long period of time and is free from danger of fire, by blending a particular lubricating oil component with a dispersant component selected from among water-soluble cationic high-molecular compounds and water-soluble amphoteric high-molecular compounds. CONSTITUTION:At least one lubricating oil component selected from among mineral oil, aliphatic alcohol, and fatty acid (ester) is blended with 0.1-10wt% dispersant component selected from among an addition polymer, a ring-opening polymer and a polycondensation product which is a polymer containing at least two basic or cationic nitrogen atoms and having an average MW of 1,000-10,000,000 and additives such as 0-5wt% extreme pressure agent, 0-2wt% rust preventive and 0-5wt% antioxidant, thereby obtaining the titled compsn. 1-30wt% aforesaid compsn. is diluted with 99-70wt% water for use. |
