Anti-corrosion motor vehicle antifreeze fluid

Abstract

The invention discloses anti-corrosion motor vehicle antifreeze fluid. The raw materials include, by mass, 80-90 percent of ethanediol, 0.05-0.15 percent of pigment, 0.5-1.5 percent of zinc chloride, 0.05-0.15 percent of methyl-1H-benzotriazole, 0.5-1.5 percent of sodium tetraborate, 0.5-1.5 percent of polyamino acid and the balance deionized water. The anti-corrosion motor vehicle antifreeze fluid is high in anti-corrosion performance, can effectively prevent water scales from forming, has good protection performance for any materials of a cooling part of an engine, has the excellent performance of preventing freezing in winter, preventing boiler in summer, preventing water scales and corrosion all the year round and the like, effectively protects a water cooling system of a motor vehicle, prolongs the service life of the water cooling system, reduces the cost and further has the advantage of being environmentally friendly.

Description

technical field [0001] The invention relates to an antifreeze liquid, in particular to an anti-corrosion automobile antifreeze liquid. Background technique [0002] The earliest automobile engines were of two types, water-cooled and air-cooled. Water-cooled engines had a better cooling effect due to heat dissipation through radiators, so they were more and more widely used in high-power automobile engines. Water is a good heat transfer medium, but it does not have antifreeze effect in low temperature weather, so it is necessary to add a substance that can lower the freezing point of water in water, so that the coolant has antifreeze effect and can be used in vehicles or engines all year round . Inorganic salts were originally used in cooling liquids to lower the freezing point, but due to severe corrosion, the cooling system materials used in the early days were not widely used. Another class of substances that can lower the freezing point are polysaccharides, but they hav...
