Description
Technical field
The invention belongs to corrosion and the guard technology field of metallic substance, refer more particularly to a kind of aluminium Anti-corrosion antifreeze liquid.
Background technology
Deicing fluid is a kind of cooling fluid containing special additive, has winter antifreeze, and summer prevents premium propertiess such as boiling.In order to make solar water heater when temperature is too low, be unlikely to frost crack pipe, normally adopt binary cycle system, namely interchanger is set in solar water heating system, the hot side of heat collector and interchanger forms first and circulates, and use subzero deicing fluid to make heat-transfer working medium, thus realize the antifreeze of system.Now domestic and international more than the 95% aq. type deicing fluid using ethylene glycol, ethylene glycol is antifreeze, boiling point is high, volatility is little, modest viscosity and along with temperature variation little, Heat stability is good, but the meta-bolites of ethylene glycol has severe toxicity, big for environment pollution, the environmental protection advocated with country does not conform to.In addition, because the pipeline in solar energy circulating system is made up of all kinds of metal, so in order to avoid the material corrosion that deicing fluid causes in long term operation, extend the work-ing life of water-heater, in deicing fluid, also should add inhibiter, reach the effect of anti-inhibition.
The development experience of current inhibiter is from the traditional metal materials such as iron and steel, copper to the protection of the Novel light such as aluminium, magnesium alloy material and many metal composite structures, and the research about these alloy material corrosion preventions is also increasing.Aluminium inhibiter has three classes: adsorptivity inhibiter, mainly through the chemisorption of physical adsorption and covalent linkage, forms firmly adsorption film, medium and metal are kept apart at molecular surface, thus suppresses corrosion of metal; Diffustivity inhibiter, inhibitor molecular acts on the full surface of metal, and be that the resistance in the microbattery of local increases, corrosion current reduces, and the corrosion of aluminium is suppressed; Surface change type inhibiter, carry out chemical reaction with metal, reactant is covered on metallic surface.
Domestic research in corrosion of aluminium alloy protection is started late, be at first from inorganics, as molybdate, tungstate etc. have certain corrosion mitigating effect, nowadays organic inhibitor is developed into, the research of aluminium inhibiter in pursuit simultaneously efficiently, gradually to nontoxic, green, environmental protection, economic future development, and utilize rare-earth salts substitute to environment have the traditional chromium hydrochlorate of pollution become corrosive protection of aluminium alloy field development trend, composite by structures and characteristics having complementary different compounds in addition, realize synergistic corrosion inhibition, it is then an important research direction of aluminium inhibiter.
Summary of the invention
The object of this invention is to provide one and both can ensure that solar energy system heat transfer effect, again aluminium alloy is had to the aluminium Anti-corrosion antifreeze liquid of good corrosion inhibition, to overcome inhibiter poorly water-soluble, to the problem such as environment is unfriendly.
The invention provides a kind of aluminium Anti-corrosion antifreeze liquid, its preparation method is:
Step one: make benzotriazole, Polysorbate 80, rare-earth salts, cats product, sodium alizarinsulfonate be dissolved completely in propylene glycol and glycerol by ultrasonic vibration;
Step 2: add water, until the benzotriazole concentration in solution is 0.1-1.4 grams per liter, Polysorbate 80 concentration be 1-2 milliliter/liter, rare-earth salts concentration is 0.01-0.1 grams per liter, cationic surfactant concentration is 0.05-0.3 grams per liter, sodium alizarinsulfonate concentration is 0.001-0.008 grams per liter, PG concentration is 150-500 milliliter/liter, glycerol concentration be 100-450 milliliter/liter;
Step 3: repeatedly stir.
Preferred technical scheme has: a kind of aluminium Anti-corrosion antifreeze liquid, it is characterized in that being made up of benzotriazole, Polysorbate 80, rare-earth salts, cats product, sodium alizarinsulfonate, propylene glycol, glycerol, wherein benzotriazole concentration is 0.8 grams per liter, Polysorbate 80 concentration is 1.5 milliliters/liter, rare-earth salts concentration is 0.05 grams per liter, and cationic surfactant concentration is 0.15 grams per liter, sodium alizarinsulfonate concentration is 0.004 grams per liter, PG concentration is 300 milliliters/liter, glycerol concentration is 300 milliliters/liter; Described rare-earth salts is cerous salt; Described cationic surfactant is aminopyrazole derivatives.
Aluminium of the present invention is interacted by the aluminum ion that generates in the reactive group on its molecule and corrosion process with the benzotriazole in anti-corrosion preservative component and forms precipitation membrane or insoluble coordination compound film and play corrosion inhibition.Polysorbate 80 belongs to nonionic surface active agent, it contains polar group and non-polar group, and when it adds in corrosive medium, polar group can adsorb in aluminum alloy surface, make non-polar group align in aluminum alloy surface, stop corrosive medium thus play corrosion inhibition.Sodium alizarinsulfonate and cats product form stable associated complex and cover aluminum alloy surface, add rare-earth salts simultaneously, and act synergistically between these inhibiter, make the protective membrane of aluminum alloy surface complete, thus suppress the corrosion of aluminium alloy.
Aluminium Anti-corrosion antifreeze liquid viscosity provided by the invention is little, improves heat transfer effect; Simultaneously by changing component proportion, obtaining different freezing point scopes, being suitable for different areas and using and reduce costs.And all more than 91% is reached to the inhibition efficiency of aluminium alloy, and environmentally friendly, do not destroy original technical process, do not need optional equipment, easy to use, smail investments and quick rerurn.
