FIELD: chemistry.

SUBSTANCE: present invention relates to a lubricant coolant concentrate, which contains products of reaction of triethanolamine with oleic acid, boric acid, monoalkylphosphoric acid, target additives - antifoaming agent and a fragrance and water, wherein reaction product of triethanolamine and oleic acid used is triethanolamine soap of oleic acid and triethanolamine soap of oxyethoxylated oleic acid at 7 moles of ethylene oxide, product of reacting triethanolamine with boric acid used is a product of reacting triethanolamine with modified boric acid, product of reacting triethanolamine with monoalkylphosphoric acid used is a product, where alcohol agent is polyethylene glycol 400, concentrate further contains an aqueous solution of polyethylene glycol 1500 in concentration of 30-35 wt% and a copper inhibitor, in form of a product of reacting benzotriazole with triethanolamine in weight ratio of 1:5, in following ratio of components, wt%: triethanolamine oleic acid soap - 10.0-20.0; triethanolamine soap of oxyethylated oleic acid at 7 moles of ethylene oxide - 10.0-12.0; product of reacting triethanolamine with modified boric acid - 25.0-28.0; product of reacting triethanolamine with monoalkylphosphoric acid, where alcohol agent is polyethylene glycol 400, - 25.0-30.0; aqueous solution of 30-35 % of polyethylene glycol 1500 - 10.0-12.0; product of reacting benzotriazole with triethanolamine in weight ratio of 1:5 - 0.3-0.5; antifoaming agent - 0.05-0.07; fragrant - 0.003-0.005; water - up to 100 %.

EFFECT: technical result of present invention is development of lubricant coolant concentrate having high performance: improved lubrication, anti-wear, inhibiting properties for machines, processing aluminium alloys, titanium materials, ferrous and nonferrous metals, steel and alloys thereof, with supply of working solution of lubricant coolant at high pressure (from 4 to 10 atm), with low foaming, relatively high wetting and detergent properties and with sufficiently high quality of processed surface.
