LUBRICATING AND COOLING LIQUID FOR TOOLING OF METALS, METHOD FOR ITS PRODUCTION, EMULSION LUBRICATING AND COOLING LIQUID Russian patent published in 1997 - IPC

Abstract RU 2083645 C1

FIELD: oil processing and treatment of metals. SUBSTANCE: proposed liquid contains mineral oil and product of ozonolysis of oil resinous-asphaltene material (RAM) being used as additive. Method involves ozonation of 5-15 % solution of RAM, the process is carried out in mineral oil at temperature up to 80 C, expense of ozone being up to 4 moles per 1 mole of RAM. The process is followed by sustaining at 120-130 C within 1-2 h, cooling and separation of precipitate. Thus prepared lubricating and cooling liquid may be used as self-emulsifying oil represents 3-10 % aqueous-oil emulsion, pH of aqueous phase being 7.5-10. EFFECT: improved quality of desired product, improved efficiency of the method. 4 cl, 2 tbl
