Abstract

The invention discloses engine cooling liquid. The engine cooling liquid comprises, by weight, 30-70 parts of ethylene glycol, 10-30 parts of propylene glycol, 0.5-1.5 parts of silicate, 0.2-0.8 part of petroleum sulfonate, 0.1-0.6 part of molybdate, 0.1-0.8 part of azole compound, 0.5-3 parts of preservatives, 0.1-0.5 part of silicate stabilizer, 0.4-1.2 parts of defoaming agent, 0.08-1 part of pH regulator, 0.01-0.02 part of dyeing agent, 0.2-0.6 part of dimethyl sulfoxide, 0.05-0.4 part of isothiazolinone and the balance deionized water. The engine cooling liquid is good in freezing resistance, corrosion resistance, scaling resistance and boiling resistance.

Description

technical field [0001] The invention belongs to the technical field of engine cooling, and in particular relates to an engine coolant. Background technique [0002] Coolant, also known as antifreeze, antifreeze, etc., if the engine is overheated, it will lead to a decrease in inflation efficiency and a decrease in engine power; it will also increase the tendency of early ignition and deflagration, deteriorate the lubrication between moving parts, and aggravate its wear , Premature damage to components. With the development of the automobile industry, the performance requirements of the engine are getting higher and higher, not only requiring the coolant to have a lower freezing point and a higher boiling point, but also requiring better anti-fouling and anti-corrosion properties. Contents of the invention [0003] The object of the present invention is to provide an engine coolant, which not only has a lower freezing point and a higher boiling point, but also has better a...
