Abstract

The invention discloses anti-freezing mother liquor with good stability and a preparation method thereof. The preparation method comprises the following steps of: taking purified water, carrying out ultraviolet sterilization on the purified water, carrying out reverse osmosis filtration treatment, then feeding the purified water into an electric desalting device for treatment to obtain desalted water, and carrying out distillation treatment on the desalted water to obtain ultrapure water; adding the obtained ultrapure water into a reaction kettle, then adding ethylene glycol into the reactionkettle, performing high-speed stirring on the mixture through the reaction kettle at a temperature of 60-75DEG C for 30min, and then stopping stirring; performing low-temperature heating at 35-45DEG C, sequentially adding sodium benzoate, disodium hydrogen phosphate, benzotriazole, triethanolamine and hydrolyzed maleic anhydride into the reaction kettle, performing high-speed stirring treatment onthe later added solvents through the reaction kettle, and performing secondary stirring at a speed of 650-900r/min during stirring. Compared with the prior art, the anti-freezing mother liquor provided by the invention has the advantages of high corrosion resistance, good radiating effect and high stability, better solves the problems of metal corrosion and stored precipitate layering, and is notprone to scaling in use and high in use stability.

Description

technical field [0001] The invention belongs to the technical field of antifreeze, and in particular relates to an antifreeze mother liquid with good stability and a preparation method thereof. Background technique [0002] The boiling point of the existing antifreeze is relatively close to the freezing point, which is not conducive to the use in double extreme temperature environments. The use range is low, and the foam volume is large, the heat transfer efficiency is average, the heat dissipation is poor, the stability is low, and precipitation will occur during storage. The problem of delamination, the use stability is low, and it is easy to generate scaling. Contents of the invention [0003] The object of the present invention is to provide a kind of antifreeze mother liquor with good stability and preparation method thereof, to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention...
