CONCENTRATE OF CUTTING LIQUID FOR DIE CASTING OF NON- FERROUS METALS Russian patent published in 1997 - IPC

FIELD: manufacture of castings from zinc and aluminium alloys. SUBSTANCE: concentrate for die casting of non-ferrous alloys, (comprises kerosene), oleic acid, triethanolamine, sodium soap of fatty acids and polysiloxane liquid, the carrier is mineral oil and water, the ratio of components being as follows (wt%): 10.0-30.0 mineral oil; 5.0-8.0 kerosene; 8.0-10.0 oleic acid; 4.0-5.0 thriethanol amine; 2.0-2.5 sodium soap of fatty acids; 1.9-2.1 polysiloxane liquid; and the water balance. Concentrate of cutting liquid makes it possible to improve quality of the resulting castings and reduce contamination of mold surface. EFFECT: improved properties of the concentrate of cutting liquid.
