The preservative is one or more of carbazone, 1, 2-hexanediol and ethylene glycol phenyl ether, the corrosion inhibitor is one or more of borax, phosphate, nitrite, nitrate and molybdate, the scale inhibitor is one or more of phosphate and chlorate, the foam suppressor uses one or more of alkyl nonionic surfactant, one or more of rotary glyceryl ether, alcohol and silicone, the colorant is one of methyl red, phenol red and methylene blue, the sterilization and mildew preventive is sodium benzoate, and the pH regulator is one or more of organic amine, phosphate and phosphate.
Different ratios of ethylene glycol to deionized water form different freezing points:
| de-ionized water/%) | Ethylene glycol/%) | Freezing point/. degree.C |
| 40 | 50 | -30℃ |
| 42 | 52 | -32℃ |
| 44 | 55 | -29℃ |
| 37 | 59 | -45℃ |
In summary, it can be seen from the comparison of the data that the ratio of ethylene glycol to deionized water is 59%: when the concentration is 37%, the freezing point of the antifreeze reaches the maximum, the proportion is the optimal proportion, and the proportion of other reagents added into the antifreeze is low, so that the manufacturing cost of the product can be reduced, and the efficient preparation of the product is facilitated.
The function of adding the foam reducing agent into the antifreeze liquid is as follows: as the automobile engine inevitably vibrates in the running process, air enters the antifreeze solution to generate certain foam. This affects the heat transfer. And a proper amount of defoaming agent is added into the antifreeze, and when the concentration of the defoaming agent reaches a certain amount, a defoaming effect can be achieved. The antifreezing solution is added with a nontoxic water-soluble colorant for the following functions: the addition of the water-soluble colorant facilitates the observation of the pH value change of the antifreeze. If the observed color does not match the indicating color, the antifreezing agent is acidic, and the acidity does not play a role in preventing freezing and rust. The function of adding the sterilization mildew preventive into the antifreeze fluid is as follows: because microorganisms are easy to generate in the process of storing the antifreeze, a small amount of sterilization and mildew-proof agent is required to be added in order to inhibit the growth of the microorganisms and prevent the antifreeze from mildewing and deteriorating, so that the antifreeze is prevented from mildewing in the storage period of 2-3 years. As the PH value of the antifreeze can be reduced and the medium can be changed into acid in the working process, the PH value can be controlled within a certain range by adding the corrosion inhibitor.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
