Antifreezing cooling liquid

Abstract

The invention discloses an antifreezing cooling liquid which is composed of the following raw materials in parts by weight: 2-3 parts of ethylene glycol monoethyl ether acetate, 1-2 parts of 1,2-propanediol, 2-4 parts of polyethylene glycol, 2-3 parts of acrylic acid, 3-5 parts of ethylene glycol, 2-3 parts of azelaic acid, 3-4 parts of octanedioic acid, 4-5 parts of dibutyl sebacate, 2-4 parts of adipic acid, 3-4 parts of boric acid, 4-5 parts of sodium fluosilicate, 3-4 parts of calcium silicate, 3-5 parts of dimethicone, 2-5 parts of cinnamic acid, 4-6 parts of styrene, 2-4 parts of sorbitol and 100-120 parts of pure water. The antifreezing cooling liquid is good in storage stability and has a good inhibition effect on corrosion of aluminum and aluminum alloy.

Description

technical field [0001] The invention relates to the technical field of cooling liquid, in particular to an antifreeze cooling liquid. Background technique [0002] At present, the antifreeze coolant mostly adopts the aqueous solution of ethylene glycol, adding phosphate and boric acid additives in the aqueous solution of ethylene glycol can make the antifreeze coolant play a good role in inhibiting the corrosion of copper and iron, but as the aluminum alloy Widely used in the cooling system of automobile engines, the disadvantage of this kind of antifreeze coolant being highly corrosive to the surface of aluminum has gradually emerged. Corrosion of aluminum alloys. [0003] However, because the silicate is very unstable, the storage stability of the antifreeze coolant containing silicate is poor, and precipitation is easy to form, which affects the inhibition of the antifreeze coolant to the corrosion of aluminum and aluminum alloys.
