Abstract
The present invention discloses a corrosion-resistant automotive antifreezing solution. The antifreezing solution consists of the following raw materials in parts by weight: 8-12 parts of ethylene glycol; 4-7 parts of disodium hydrogen phosphate; 3-5 parts of polyacrylic acid; 4-8 parts of isobutyl acrylate; 3-5 parts of sodium benzoate; 1-2 parts of sodium tetraborate; 2-4 parts of triethanolamine; 2-5 parts of carboxymethylcellulose; 1-3 parts of borates; 1-3 parts of phosphates; 0.01-0.05 part of 4-methyl benzotriazole; and 0.01-0.05 part of 5-methyl benzotriazole. The antifreezing solution disclosed by the present invention has excellent rust and corrosion resistance, thereby prolonging the service life of an automotive cooling system.
Description
Technical field
The invention belongs to freezing proof technique field, be specifically related to corrosion automobile antifreeze solution.
Background technology
Winter temperature is low, and still can continue under low temperature in the winter time for making automobile to use, engine coolant all adds some materials that can reduce water-ice point as frostproofer, and when remaining on microthermal climate, cooling system does not freeze.Along with the development of automotive industry, also more and more higher to the performance requriements of engine, not only require that deicing fluid has lower freezing point and higher boiling point, also should have good metal subunits, cavitation-preventive, good antiscale property, and environmental pollution is little or free from environmental pollution, and there is the over-all properties of longer work-ing life etc. aspect.Domestic deicing fluid majority does not possess corrosion, has the deicing fluid of some anti-corrosion performances can not meet the higher requirement of people.
Summary of the invention
For the deficiencies in the prior art, the invention provides corrosion automobile antifreeze solution, anti-corrosion performance is good, extends automobile cooling system work-ing life.
Technical scheme of the present invention is: corrosion automobile antifreeze solution, is made up of the raw material of following parts by weight: ethylene glycol 8-12 part, Sodium phosphate dibasic 4-7 part, polyacrylic acid 3-5 part, isobutyl acrylate 4-8 part, Sodium Benzoate 3-5 part, sodium tetraborate 1-2 part, trolamine 2-4 part, carboxymethyl cellulose 2-5 part, borate 1-3 part, phosphoric acid salt 1-3 part, 4-tolyltriazole 0.01-0.05 part, 5-tolyltriazole 0.01-0.05 part.
Compared with prior art, the invention has the advantages that: the 4-tolyltriazole of interpolation and 5-tolyltriazole mixture, as rust-preventive agent, inhibiter, have well antirust, Corrosion Protection, extend automobile cooling system work-ing life.
