Automobile engine compound antifreezing solution

Abstract

The invention discloses a composite antifreeze fluid for automobile engines, which is composed of the following ingredients in parts by weight: 20-30 parts of ethylene glycol; 5-10 parts of triethanolamine; 20-30 parts of calcium iodide; and 0.1-0.5 parts of sodium silicate 1-3 parts of potassium permanganate; 2-3 parts of zinc acetate; 0.1-0.5 parts of brassinolide; 0.3-0.5 parts of vinyl acetate; 1-2 parts of sebacic acid; The solution has the characteristics of adhesion, thickening, flow, emulsification and dispersion, shaping, water retention, protective colloid, film forming, acid resistance, salt resistance, suspension, etc., and is physiologically harmless. The antifreeze of the present invention has high viscosity and a viscosity value of 8- 9MPa·S, the trailer effect is good, and its freezing point is below -48°C, which ensures the antifreeze effect.

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. At...

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
