CONCENTRATE OF WATER-LUBRICATING-COOLING LIQUID Russian patent published in 2020 - IPC C10M159/08 C10M101/04 C10M129/00 C10M129/02 C10M133/02 

FIELD: chemistry.

SUBSTANCE: invention relates to compositions of lubricant-coolant process agents, in particular to lubricant-cooling liquids (LCL) concentrates, which can be used in form of aqueous emulsions in machine building on operations of blade and abrasive processing of ferrous metals and their alloys. Content of the concentrate of water-mixed LCL, which as fatty acids contains non-distilled fatty acids, extracted from soap stocks of vegetable oils processing, emulsifier contains triethanolamine, as stabilizer contains ethyl cellosolve, as alkali metal hydroxide – sodium hydroxide, and as anticorrosion additive contains neutral calcium sulphonate at following ratio of components, wt%: fatty acids extracted from soap stocks of processing vegetable oils, non-distilled 20–40, triethanolamine 15–25, ethyl cellosolve 20–40, sodium hydroxide 0.5–1.5, neutral calcium sulphonate 0.3–0.7, technical sunflower oil 100.

EFFECT: formulation of a composition which meets the quality requirements of a water-miscible LCL concentrate which has improved anticorrosive properties and high stability of the LCL obtained therefrom.
