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.
