Efficient corrosion-resistance anti-freezing fluid for automobile

Abstract

The invention discloses an efficient corrosion-resistance anti-freezing fluid for automobile. The anti-freezing fluid is characterized by being prepared from the following components in parts by weight: 10-20 parts of polyacrylic acid, 0.5-1 part of poly(sulfonated styrene), 10-15 parts of silicone, 0.1-1 part of sodium molybdate, 5-10 parts of water-soluble anti-rust additive, 3-5 parts of methyl silicon oil, 4-5 parts of carboxymethyl cellulose, 2-4 parts of methyl tertiary-butyl ether, 0.4-0.6 part of triolamine phosphate, 5-10 parts of phosphoric acid, 0.5-1 part of sodium hydroxide, 5-10 parts of water-soluble anti-rust additive and 5-10 parts of water. The anti-freezing fluid is low in cost, can be used for resisting freezing, icing, rusting, scaling and descaling, and does not need to be changed in three years.

Description

technical field [0001] The invention relates to an antifreeze liquid, which belongs to the field of chemical industry, in particular to a high-efficiency anti-corrosion automobile antifreeze liquid. Background technique [0002] Most of the cooling systems of vehicles use water as the heat exchange medium. Since water freezes at low temperatures, its volume increases by 9%. If the water in the cooling system is not released after the vehicle is driven in winter, the cooling system will burst due to freezing. , and long-term use of water as the exchange medium will corrode the metal parts and affect the structure of the heat exchange, shortening the life of the engine. Antifreeze can prevent the coolant from freezing when the car is parked in cold winter, causing the radiator to burst and the engine cylinder block to be frozen. or cover. Automobiles, trains, diesel locomotives, tractors, ships, engines, water tanks, and various mechanical equipment, diesel engines, gasoline ...

Problems solved by technology

Therefore, the antifreeze not only needs to have good cooling performance, but also has the functions of anti-freezing and anti-rust and anti-scaling. The antifreeze on the market basically meets these needs, but the price is on the high side.
