FIELD: metal working by means of lubricant-and-coolants; aqueous solutions of lubricant-and-coolants for treatment of metals and alloys. ^ SUBSTANCE: proposed concentrate has the following composition, mass-%: triethanolamine, 28-31; oxyethylated alkyl phenol, 8-11;urotropin, 5.5-6.5; borax, 0.8-1.2; alkyl dimethyl benzyl ammonium chloride, 4.6-5.5; 1,4-btanedione, 10-12; decylic alcohol, 0.8-1.2; water, up to 100. It is preferably, that concentrate contains process water at carbonate hardness not higher 4 mg.eq./l. Use of proposed liquid makes it possible to reduce roughness of surfaces being treated to 0.85 mcm. ^ EFFECT: increase of resistance of cutting tools to 90 min. ^ 2 cl, 2 tbl |
