Problems solved by technology

[0004] If it is not handled properly, the antifreeze will easily corrode metal parts during use, and the metal parts that have been corroded for a long time will generate a large amount of rust, which will gradually corrode the metal plate and cause leakage, which is directly related to the service life of the car cooling system; At the same time, scale is easy to form. The thermal conductivity of scale is small, which is 1/25 of that of cast iron and 1/50 of that of brass, which greatly reduces the thermal conductivity of the coolant and seriously reduces the cooling effect; the temperature of the engine increases and the corrosion increases, which further promotes Scale increases, forming a vicious

Abstract

The invention belongs to the technical field of antifreeze fluid and discloses an automotive antifreeze fluid and a preparation method thereof. The automotive antifreeze fluid is prepared from, by mass, 400.0-600.0%o of polyalcohol, 1.0-5.0%o of acrylic acid-acrylate-sulfonate ternary copolymer, 1.0-5.0%o of polyoxyethylene polyoxypropylene segmented copolymer, 5.0-10.0%o of organic amine, 0.5-5.0%o of benzotriazole, 0.5-5.0%o of accelerants, 0.5-5.0%o of sodium hydroxide, 0.5-5.0%o of sodium nitrate, 0.5-5.0%o of sodium metasilicate, 2.0-8.0%o of organic acid, 0.005-0.5%o of sodium fluorescein, 0.005-0.5%o of turquoise blue pigment, 0.005-0.5%o of an anti-foaming agent and the balance deionized water. The automotive antifreeze fluid has advantages of low freezing point, high boiling point, excellent anti-freezing and anti-boiling performances and great corrosion resistance and anti-scaling performances.

Description

technical field [0001] The invention belongs to the technical field of antifreeze, and in particular relates to an automobile antifreeze and a preparation method thereof. Background technique [0002] Antifreeze, also known as antifreeze coolant, is used to prevent the coolant from freezing and bursting the radiator and freezing the engine cylinder when the vehicle is parked in cold winter. Antifreeze is used in the cooling systems of automobiles, trains, diesel locomotives, tractors, ships, engines, water tanks, and various mechanical equipment, diesel engines, and gasoline engines. In the coolant path of the internal combustion engine, there are materials such as aluminum, cast iron, steel, brass, solder, copper, etc., and the antifreeze should be able to effectively inhibit the corrosion of these materials. Therefore, the antifreeze should not only have good cooling performance, but also have the functions of anti-freezing, anti-rust and anti-scaling. [0003] The measu...
