Abstract
The invention discloses a multifunctional corrosion-resistant antifreeze fluid composed of the components of, by weight: 10-30 parts of diethylene glycol, 5-10 parts of sodium molybdate, 3-10 parts of glycerin, 2-8 parts of phosphoric acid, 1-5 parts of polysorbate, 1-5 parts of poly-styrene sulfonate, 1-10 parts of phosphate potassium dihydrogen, and 10-20 parts of deionized water. The multifunctional corrosion-resistant antifreeze fluid has the advantages that: with heterocyclic compounds such as benzotriazole in the antifreeze fluid, through the interaction of the reaction groups on organic corrosion-retarding agent molecules and the aluminum ions on the surface of metal produced during a corrosion process, a precipitation film or insoluble complex film is formed, and a corrosion-retarding effect is achieved. According toteh invention, propylene glycol and glycerol with low viscosity are adopted, such that the heat exchange effect of a solar system is ensured.
Description
Technical field
The invention belongs to corrosion of metal and guard technology field, especially a kind of Multifunctional corrosion resistant erosion deicing fluid.
Background technology
At present, countries in the world are many to deicing fluid patent application, main component is ethylene glycol and water, and add sanitas, rust-preventive agent, stablizer, colors staining agent, individual other also added permeability-reducing admixture, for example Chinese patent 201110252501.5, but the potassium nitrite containing in inhibiter component is harmful to HUMAN HEALTH.If single with regard to regard to the corrosion mitigating effect of carbon steel, chromic salt, especially coordinates the chromic salt with poly-phosphate and zinc salt, remains so far ideal person in inhibiter.The U.S. is still applying it to a great extent.But chromic salt is poisonous, to environment.Therefore, worldwide oneself is replaced by (gathering) phosphoric acid salt gradually.But phosphoric acid salt is the nutrition source of microorganism in water, its discharge can cause body eutrophication, and result, from another point of view to environment.Therefore, environment and human body have been become to an important direction of current inhibiter research field without the research and development of the environmentally friendly inhibiter of harm.Think that after deliberation substitute ，Er China that rare earth is expected to become chromic salt is again the country that rare-earth ore resource is the abundantest in the world, kind is more complete, still, simple rare earth is large as inhibiter consumption, and effect neither be very stable.
Summary of the invention
The deficiency existing for prior art, technical problem to be solved by this invention is, a kind of good stability and environmental protection are provided,
Can all reach more than 90% Multifunctional corrosion resistant erosion deicing fluid to the inhibition efficiency of aluminium alloy and carbon steel again.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of Multifunctional corrosion resistant erosion deicing fluid, is comprised of the composition of following weight part:
10～30 parts of Diethylene Glycols;
5～10 parts of Sodium orthomolybdates;
3～10 parts of glycerol;
2～8 parts of phosphoric acid;
1～5 part of polysorbate;
1～5 part of poly-sulfonated phenylethylene;
1～10 part of potassium primary phosphate;
10～20 parts of deionized waters.
The advantage of Multifunctional corrosion resistant of the present invention erosion deicing fluid is: the aluminum ion of the heterogeneous ring compounds such as benzotriazole in deicing fluid component that the present invention is anti-corrosion by the metallic surface that generates in the reactive group on organic inhibitor molecular and corrosion process interacts and form precipitation membrane or insoluble coordination compound film plays corrosion inhibition, thereby the present invention has guaranteed the heat transfer effect of solar energy system by the little propylene glycol of viscosity and glycerol, and more than the inhibition efficiency of aluminium alloy and carbon steel is all reached to 90 %, there is suitability strong, less investment, environmentally friendly, do not need the advantages such as optional equipment.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in further details;
Embodiment 1:
