Abstract

The invention discloses an anti-boiling, anti-scale and anti-freeze solution and belongs to the technical field of anti-freeze solutions. The anti-boiling, anti-scale and anti-freeze solution is obtained through reaction of 100 parts to 120 parts of ethanediol, 60 parts to 80 parts of deionized water, 15 parts to 30 parts of corrosion inhibitor, 5 parts to 10 parts of silicate, 6 parts to 8 parts of silicate stabilizer, 2 parts to 4 parts of mildew preventive, 5 parts to 10 parts of pH modifier, 1 part to 3 parts of defoamer and 1 part to 5 parts of colorant, wherein the pH modifier is disodium hydrogen phosphate. According to the anti-boiling, anti-scale and anti-freeze solution, by increasing the proportion of the deionized water in the antifreeze, the boiling point is raised while the freezing point is lowered, the quality of the anti-freeze solution is improved to a certain extent, the long-acting anti-boiling performance is achieved by adding various auxiliaries in the subsequent process, and the anti-boiling, anti-scale and anti-freeze solution is low in price and free of pollution, sediment and scaling. A preparation method of the anti-boiling, anti-scale and anti-freeze solution is simple in step, environmentally friendly and easy to carry out.

Description

technical field [0001] The invention belongs to the technical field of antifreeze, and in particular relates to an anti-boiling and anti-scaling antifreeze and a preparation method thereof. Background technique [0002] The full name of antifreeze should be called antifreeze coolant, which means coolant with antifreeze function. [0003] The cooling medium of the engine circulation cooling system, and the working state of the cooling system directly affects the normal operation and [0004] The service life of the vehicle, antifreeze is not only used in winter, it should be used throughout the year. Traditional antifreeze is mainly composed of antifreeze and additives, not only the production cost is high. The finished coolant is prone to mildew during storage, and it is difficult to take into account the anti-boiling and anti-scaling functions, which may easily lead to the phenomenon of "boiling" the engine.
