Description
Technical field:
The present invention relates to a kind of automobile engine cooling liquid, especially relate to a kind of automobile engine cooling liquid of environment-friendly type.
Background technology:
Automobile engine cooling liquid is the circulating heat transfer medium in car water engine-cooling system, be make engine work, operate requisite integral part, it directly affects the work-ing life of automobile.The major function of deicing fluid is: take away the heat that engine produces at work; Prevent from high temperature seething with excitement and freeze under low temperature; Protection engine-cooling system metalwork, prevents corrosion, corrosion and cavitation erosion; Prevent engine-cooling system from affecting heat transfer efficiency because of fouling.
Deicing fluid in the market adopts ethylene glycol to make frostproofer substantially.But to be a kind of toxicity large and be difficult to biodegradable compound for ethylene glycol, and the environmental issue that the deicing fluid making frostproofer by ethylene glycol brings also day by day receives the concern of people.In addition, existing engine coolant amine, nitrate, nitrite, phosphoric acid salt and borate do inhibiter, and these are all the materials to human body and bad environmental, and easily produce metallic corrosion, the metalwork of corrode engine cooling system, formulation stability is poor.
Goal of the invention:
Technical problem to be solved by this invention is to provide a kind of environment-friendly type cooling fluid, and it has good corrosion inhibition to the metalwork of engine-cooling system, and formulation stability is good, has long-acting suppression corrosive power.
Above-mentioned purpose is achieved in that it contains propylene glycol, glycerol, lipid acid, azole compounds, potassium sorbate, sodium hydroxide, defoamer, water-soluble dye, deionized water; Wherein propylene glycol accounts for the 20-60% of gross weight of the present invention, glycerol accounts for the 1-20% of gross weight of the present invention, lipid acid accounts for the 0.3-5.0% of gross weight of the present invention, azole compounds accounts for the 0.01-1.0% of gross weight of the present invention, potassium sorbate accounts for the 0.05-2.0% of gross weight of the present invention, and sodium hydroxide accounts for the 0.01-2.0% of gross weight of the present invention, and defoamer accounts for the 0.001-0.2% of gross weight of the present invention, water-soluble dye accounts for the 0.001-0.1% of gross weight of the present invention, and surplus is deionized water.
Described azole compounds is one or both mixture of benzotriazole or methyl benzotriazazole, and blending ratio is not limit.
Described lipid acid is sad or a kind of or several arbitrarily mixture of isocaprylic acid or sebacic acid or hexanodioic acid or celebrating diacid or nonane diacid, and blending ratio is not limit.
Described defoamer is silicone antifoam agent.
Described water-soluble dye can be fluorescent green dye.
Specific practice is: according to the weight percent of the described each component of formula, propylene glycol, glycerol and deionized water are added in reactor, stirring at normal temperature 30 minutes, then sodium hydroxide, lipid acid, azole compounds and potassium sorbate are added in reactor successively, stir and add defoamer and water-soluble dye again after 1 hour, until dissolve completely.
Advantage of the present invention is: this cooling fluid adopt propylene glycol make frostproofer, add appropriate glycerol, glycerol by biological extraction, environmentally safe.Inhibition system, based on organic acid and salt thereof, adds the composition compound slow corrosion systems such as triazole class compounds simultaneously.The present invention has selected nontoxic inhibiter and biodegradable frostproofer, avoids the injury in the past brought to human and environment because adding a large amount of harmful compound.
Engine coolant of the present invention is containing the material to human body and bad environmental such as amine, nitrate, nitrite, phosphoric acid salt and borate, selected organic acid, azole compounds and potassium sorbate are combined with the proportioning of the best, organic acid not easy consumption Sum decomposition, embodies between various material and has optimum synergistic corrosion inhibition simultaneously.
Because it adopts propylene glycol as refrigerant, propylene glycol zero pour is low, and boiling point is high, is a kind of good pour point depressant and boiling point elevation agent, has very wide application stable range.It adopts azole compounds as anti-corrosion of metal inhibiter, can prevent the corrosion of copper component, has certain corrosion inhibition to aluminium, cast iron simultaneously.When there is corrosion in cooling system, the pH value of cooling fluid reduces, and slightly acidic environment appears in local.Lipid acid by ion transit be molecule dissociate out be adsorbed on occur corrosion active site, prevent from corroding further generation.Thus extend the work-ing life of deicing fluid.Described potassium sorbate effectively can reduce the corrosion to metalwork, with Fatty acid compositions inhibition system.Inhibiter makes the energy state of metallic surface tend towards stability by absorption, and by nonpolar group because causing hydrophobic nature film, the diffusion of Charger transfer and etching reagent is all suppressed, thus reduces corrosion of metal.And the synergistic effect of several organic inhibitor, thus make, to various metals, there is excellent Corrosion Protection simultaneously.Described defoamer is silicone antifoam agent, can well suppress the generation of deicing fluid foam in high-speed circulating process.Water-soluble dye, carries out inspection and maintenance when being convenient to mechanical means circulating water system generation seepage.Because the present invention has selected nontoxic inhibiter and biodegradable frostproofer, it is containing the material to human body and bad environmental such as amine, nitrate, nitrite, phosphoric acid salt and borate, avoid the injury in the past brought to human and environment because adding a large amount of harmful compound, good corrosion inhibition is had to the metalwork of engine-cooling system, formulation stability is good, has long-acting suppression corrosive power.
