Novel anti-freezing solution

Abstract

The invention aims to provide novel anti-freezing solution. The novel anti-freezing solution is characterized by comprising the following components in percentage by weight: 50 to 55 percent of glycol, 0.1 to 1.0 percent of phthalic anhydride, 0.1 to 0.3 percent of monopotassium phosphate, 10 to 100 percent of water, 0.1 to 0.5 percent of promoter, 0.1 to 0.2 percent of sodium hydroxide and 0.1 to 0.2 percent of dye. A manufacturing method of the anti-freezing solution comprises the following steps of: firstly, adding water into a reaction kettle; secondly, adding the glycol into the reaction kettle and uniformly stirring the materials; and finally, adding the other components into the reaction kettle and uniformly stirring the components to obtain the novel anti-freezing solution. The novel anti-freezing solution has the advantages of preventing freezing, reducing heat loss and saving fuel, along with high heat transfer rate and low cost.

Description

technical field [0001] The invention belongs to chemical preparations, in particular to an antifreeze used in the cooling system of an automobile engine. Background technique [0002] In the cold winter, in order to ensure the normal operation of the car's cooling system, the use of antifreeze has become an inevitable choice. In fact, antifreeze has other functions in addition to antifreeze. These functions are very important to protect the normal operation of the car. If tap water or pure water is used instead of antifreeze that needs to be replaced, it means giving up driving safety. Moreover, antifreeze not only has the function of antifreezing, but also plays a very important role in antirust, anticorrosion, antiscale, antiboiling, etc., and these preventive functions are also indispensable umbrellas for automobiles. At present, the antifreeze coolant with ethylene glycol as the main component used in the automobile engine cooling system is used for the advantages of a...

AI Technical Summary

Problems solved by technology

At present, the antifreeze coolant with ethylene glycol as the main component used in the cooling system of automobile engines is used for antifreezing of automobile water tanks in winter and anti-boiling in summer, but it still has the disadvantages of high production cost and single use.
