Compound antifreezing fluid for automobile engine

Abstract

The invention discloses a compound antifreezing fluid for an automobile engine. The compound antifreezing fluid is prepared from the following components in parts by weight: 20-30 parts of ethylene glycol, 4-5 parts of methyl silicone oil, 2-4 parts of triethanolamine, 0.4-0.6 part of benzotriazole, 20-30 parts of calcium chloride, 0.1-0.5 part of sodium silicate, 1-3 parts of potassium permanganate, 1-3 parts of methyl tertiary-butyl ether, 1-2 parts of sebacic acid and 10-20 parts of deionized water. The compound antifreezing fluid has the characteristics of adhering, thickening, flowing, emulsifying and dispersing, forming, retaining moisture, protecting colloid, forming films, resisting acid and salt, suspending and the like, is physiologically harmless, has high viscosity of 8-9MPa.S and excellent adhering effect, and has a freezing point of lower than -48 DEG C, so that the antifreezing 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
