CN102108289A - Novel anti-freezing solution - Google Patents

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

Anti-freezing liquid

Technical field

The invention belongs to chemicals, be specifically related to the deicing fluid that car engine cooling system is used.

Background technology

In the winter of cold, can works better for the cooling system that ensures automobile, use deicing fluid just to become inevitable choice.In fact; deicing fluid also has some other function except antifreeze effect is arranged; these functions all are very important for protection automobile works better, if needing to replace the deicing fluid changed with tap water or pure water, just mean and have abandoned the security of driving to a certain extent.And deicing fluid not only has antifreeze function, at aspects such as antirust, protection against corrosion, anti-incrustation scale, boiling protections important effect is arranged also, and these prophylactic functions also all is the indispensable guarantor's umbrella of automobile.What use by car engine cooling system at present is the anti-freeze cooling liquid of main component with ethylene glycol, is used for anti-advantage such as boil in radiator in winter antifreeze, summer, but also has the production cost height, the single shortcoming of purposes.

Summary of the invention

The purpose of this invention is to provide a kind of low cost, effective anti-freezing liquid.

Technical solution of the present invention is:

Ethylene glycol 50-55;

Tetra hydro Phthalic anhydride 0.1-1.0;

Potassium primary phosphate 0.1-0.3;

Water 10-100;

Promotor 0.1-0.5;

Sodium hydroxide 0.1-0.2;

Dyestuff 0.1-0.2;

Earlier water is added in the reactor, adds ethylene glycol then and stir, after add other components, fully stir, all material mixings get final product.

Anti-freezing liquid provided by the invention, not only freezing point is low,-30 ℃ of uses are not frozen, safe in utilization, there is not carcinogenic problem, it is good to suppress corrosive effect, be used for radiator in winter anti-boiling in antifreeze, summer, and production cost is low, have antifreeze, heat transfer rate fast, reduce heat energy loss, fuel saving, the advantage that cost is low.
