Description
Technical field
The invention belongs to corrosion of metal and protection technology field, especially one kind can take into account two kinds of aluminium alloy and carbon steel
The Anti-corrosion antifreeze liquid of different metal.
Background technology
Anti-icing fluid is a kind of coolant containing special additive, antifreeze with winter, the premium properties such as summer anti-boiling.With
The extensive application of solar water heater, when temperature is too low, is reached using indirect type system typically on device antifreeze
Effect, i.e., be provided for coil pipe or the chuck for exchanging heat on main water box, and coil pipe or chuck are connected with heat collector sealing by connecting tube
Connect, as the pipe-line system of circulation, anti-icing fluid is added then in the circulating pipe system of above-mentioned closing.Now domestic and international 95% with
On anti-icing fluid using be all ethylene glycol aqua type, ethylene glycol is antifreeze, boiling point is high, volatility is little and with temperature change
Little, heat endurance is good, but there is also viscosity greatly, affects heat transfer effect；Metabolite has severe toxicity, big for environment pollution etc. asks
Topic.
Further, since the pipeline in solar energy circulating system is made up of each metalloid, material the most universal is carbon steel
And aluminium alloy, then in order to avoid anti-icing fluid corrodes in the material that long-term work causes, extend the service life of water heater, anti-
Freeze in liquid and should also add corrosion inhibiter, reach the effect of anti-inhibition.Corrosion inhibiter is divided into inorganic inhibitor, mainly includes chromate, Asia
Nitrate, silicate, molybdate, tungstates, Quadrafos, zinc salt etc.；Organic inhibitor, including phosphonic acids (salt), phosphine carboxylic acid, coloured glaze
Base benzothiazole, BTA, lignosulfonate etc. some containing oxynitrides heterocyclic compounds；Polymerization species corrosion inhibiter,
Mainly include the polymer chemistry thing of some oligomer such as polyethylene kind, POCA, poly-aspartate.
At present, countries in the world are relatively more to anti-icing fluid patent application, and main component is ethylene glycol and water, and adds anti-corrosion
Agent, antirust agent, stabilizer, colors staining agent, individual other be also added into permeability-reducing admixture, such as Chinese patent 201110252501.5,
But the potassium nitrite contained in corrosion inhibiter component, is harmful to health.If singly just for the corrosion mitigating effect of carbon steel,
Chromate, especially coordinates the chromate with Quadrafos and zinc salt, remains ideal person in corrosion inhibiter so far.The U.S. exists
Substantially it is being applied still.But chromate is poisonous, to environment.Therefore, worldwide oneself is gradually
(gathering) phosphate is replaced.But, phosphate is the nutrient source of microorganism in water, and its discharge can cause body eutrophication,
As a result, from another point of view to environment.Therefore, the research to environment and the environmentally friendly corrosion inhibiter of human body non-hazardous
An important direction of current corrosion inhibiter research field is had become with exploitation.Think that rare earth is expected to become chromate through research
Substitute, and China be in the world rare-earth ore resource enrich the most, the more complete country of kind, but, simple rare earth conduct
Inhibiter consumption is big, and effect is nor very stable.
102851003 A of CN disclose a kind of Anti-corrosion antifreeze liquid, by BTA, polyoxyethylene sorbitan monoleate, non-ionic table
Face activating agent, high-molecular polymer salt, heterocyclic compound, rare-earth salts, propane diols and glycerine composition, wherein BTA is dense
Spend for 0.1-2.0 grams per liters, polyoxyethylene sorbitan monoleate concentration is 1-5 ml ls, and concentration of nonionic surfactant is 0.01-0.1
Grams per liter, high-molecular polymer salt concentration be 0.1-0.2 grams per liters, heterocyclic compound concentration be 0.05-0.15 grams per liters, rare-earth salts
Concentration is 0.01-0.1 grams per liters, and PG concentration is 150-500 ml ls, glycerol concentration is 100-450 ml ls.Should
Patent is using the little propane diols of viscosity and propenyl as anti-icing fluid, it is ensured that heat transfer effect, good stability and environmental protection, environment
