Problems solved by technology

At present, most antifreezes on the market use ethylene glycol as an antifreeze. Ethylene glycol type antifreeze has a low flash point, is flammable, and will produce acidic substances after oxidation, which will reduce the pH value of antifreeze and increase the antifreeze effect of antifreeze. corrosion of metal parts

Abstract

The invention relates to the field of anti-freezing solutions for vehicles, in particular to an anti-freezing solution for a low-temperature anti-rusting vehicle. The anti-freezing solution is prepared from following materials in parts by weight through uniform mixing: 1-2 parts of borax, 1-3 parts of Kathon, 1-3 parts of sodium nitrite, 0.2-0.4 parts of benzotriazole, 1-2 parts of triethanolamine, 5-10 parts of an aqueous graphene oxide solution, 40-65 parts of glycerin, 19.5-50.78 parts of purified water, 0.01-0.05 parts of fluorescent green and 0.01-0.05 parts of tributyl phosphate. The anti-freezing solution for the low-temperature anti-rusting vehicle is good in stability and resistant to low temperature, the applicable range of the anti-freezing solution is subzero 10 DEG C-subzero 40 DEG C, the boiling range is 106 DEG C-112 DEG C, and the anti-freezing solution is not prone to volatilization and cannot block pipelines; besides, a passivation protection film can be formed on the cooling metal surface to inhibit metallic corrosion.

Description

technical field [0001] The invention relates to the field of vehicle antifreeze, in particular to a low-temperature rust-proof vehicle antifreeze. Background technique [0002] As a kind of car maintenance products, antifreeze plays a very important role in the cooling system. Most people think that the function of antifreeze is only antifreeze in winter and anti-boiling in summer. In addition, it also needs to have anti-corrosion and anti-rust effects. At present, most antifreezes on the market use ethylene glycol as antifreeze. The ethylene glycol type antifreeze has a low flash point, is flammable, and will produce acidic substances after oxidation, which will reduce the pH value of the antifreeze and increase the antifreeze resistance to the antifreeze. Corrosion of metal parts. SUMMARY OF THE INVENTION [0003] In order to overcome the above problems existing in the existing products, the purpose of the present invention is to provide a low-temperature rust-proof ve...
