Compounded anti-freezing fluid for automobile engine

Abstract

The invention discloses compounded anti-freezing fluid for an automobile engine. The anti-freezing fluid is prepared from the following ingredients in parts by weight: 20-30 parts of ethylene glycol, 5-10 parts of triethanolamine, 20-30 parts of calcium chloride, 0.1-0.5 part of sodium silicate, 1-3 parts of potassium permanganate, 2-3 parts of calcium formate, 0.1-0.5 part of fulvic acid, 0.3-0.5 part of isopropyl nitrate and 10-20 parts of deionized water. The fluid has the characteristics of adhering, thickening, flowing, emulsified dispersing, shaping, water retention, colloid protecting, film forming, acid resisting, salt resisting, suspending and the like and is physiologically harmless; according to the anti-freezing fluid disclosed by the invention, the viscosity is high, the viscosity number is 8-9MPa.S, the vehicle adhering effect is good, and the ice point is below -48 DEG C, so that the anti-freezing effect is guaranteed.

Description

technical field [0001] The invention relates to an antifreeze liquid, in particular to a compound antifreeze liquid for an automobile engine. Background technique [0002] The full name of antifreeze should be called antifreeze coolant, which means coolant with antifreeze function. Antifreeze can prevent the coolant from freezing and bursting the radiator and freezing the engine cylinder block or cover when the vehicle is parked in cold winter. But we have to correct a misunderstanding, antifreeze is not just for winter, it should be used throughout the year. In the normal maintenance items of the car, the engine antifreeze needs to be replaced every year of driving. Bulk granular goods such as coal and mineral powder transported by railways and roads in winter are easy to freeze in the vehicle, which brings great difficulties to transportation and unloading, which not only causes great economic losses to railways, ports and coal users, but also posed a safety hazard.

Problems solved by technology

Bulk granular goods such as coal and mineral powder transported by railways and roads in winter are easy to freeze in the vehicle, which brings great difficulties to transportation and unloading, which not only causes great economic losses to railways, ports and coal users, but also pose a security risk

At present, the antifreeze liquid actually used often has a low viscosity, and its viscosity value is usually around 3MPa·S. When it is sprayed on the inside of the car, it cannot exist stably inside the car, resulting in the phenomenon of freezing the car during the spraying process. It not only wastes the antifreeze, but also seriously affects the antifreeze effect, resulting in the loss of goods
