METHOD OF PREPARING EMULSOL FOR MACHINING OF METALS Russian patent published in 1999 - IPC

FIELD: metal working, more particularly, compositions for preparing cutting liquids. SUBSTANCE: in order to prepare emulsol, mineral oil with viscosity of 12-30 s at 50 C is emulsified in water with composition of triethanolamine with oleic acid and dimethyl urea- monoethanol amine condensation product. Polyethylene glycol alkylphenyl ether and hydroquinone are added to the resulting emulsion to prepare emulsol which comprises, wt. %: mineral oil, 40-60; oleic acid, 6-10; triethanol amine; 5-7; dimethylol urea-monoethanol amine condensation product 5-9; polyethylene glycol alkylphenyl ether. EFFECT: wear resistance of cutting tools under heavy cutting conditions, corrosion and microbic stability during prolonged period of service. 4 tbl
