Abstract
The invention discloses a multifunctional corrosion-resistance antifreezing fluid. The antifreezing fluid is prepared from the following components in parts by weight: 10-30 parts of diethylene glycol, 5-10 parts of sodium molybdate, 3-10 parts of glycerol, 2-8 parts of phosphoric acid, 4-5 parts of methyl silicone oil, 2-4 parts of triethanolamine, 0.4-0.6 part of benzotriazole, 1-10 parts of potassium dihydrogen phosphate and 10-20 parts of deionized water. The multifunctional corrosion-resistance antifreezing fluid has the advantages that benzotriazole and other heterocyclic compounds in the corrosion-resistance antifreezing fluid can form a precipitation membrane or an insoluble coordination compound membrane by means of the interaction effect of a reactive group on an organic inhibitor molecule and aluminum ions on a metal surface generated in a corroding process so as to play a corrosion inhibiting effect; and propylene glycol and glycerol with small viscosity are used to guarantee the heat exchange effect of a solar system.
Description
Technical field
The invention belongs to corrosion of metal and guard technology field, especially a kind of Multifunctional corrosion-resistant antifreeze 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 adds permeability-reducing admixture, such as Chinese patent 201110252501.5, but the potassium nitrite contained in inhibiter component are harmful to HUMAN HEALTH.If single with regard to the corrosion mitigating effect to carbon steel, chromic salt, especially coordinates the chromic salt with poly-phosphate and zinc salt, remains ideal person in inhibiter so far.The U.S. is still applying it to a great extent.But chromic salt is poisonous, to environment.Therefore, worldwide oneself gradually by (gathering) phosphoric acid salt is replaced.But phosphoric acid salt is the nutrition source of microorganism in water, its discharge can cause body eutrophication, result, from another point of view to environment.Therefore, without the research and development of the environmentally friendly inhibiter of harm, the important direction of of current inhibiter research field has been become to environment and human body.Think that rare earth is expected to become the substitute of chromic salt after deliberation, and China is the country that rare-earth ore resource is the abundantest, kind is more complete in the world, but simple rare earth is large as inhibiter consumption, and effect neither be very stable.
Summary of the invention
for the deficiency that prior art exists, technical problem to be solved by this invention is, provides a kind of good stability and environmental protection,
The Multifunctional corrosion-resistant antifreeze fluid of more than 90% all can be reached again to the inhibition efficiency of aluminium alloy and carbon steel.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of Multifunctional corrosion-resistant antifreeze fluid, is made up of the composition of following weight part:
Diethylene Glycol 10 ~ 30 parts;
Sodium orthomolybdate 5 ~ 10 parts;
Glycerol 3 ~ 10 parts;
Phosphoric acid 2 ~ 8 parts;
Methyl-silicone oil 4 ~ 5 parts;
Trolamine 2 ~ 4 parts;
Benzotriazole 0.4 ~ 0.6 part;
Potassium primary phosphate 1 ~ 10 part;
Deionized water 10 ~ 20 parts.
The advantage of Multifunctional corrosion-resistant antifreeze fluid of the present invention is: the heterogeneous ring compounds such as the benzotriazole in Anti-corrosion antifreeze liquid component of the present invention are interacted by the aluminum ion of metallic surface generated in the reactive group on organic inhibitor molecular and corrosion process and form precipitation membrane or insoluble coordination compound film and play corrosion inhibition, the propylene glycol that the present invention's viscosity is little and glycerol thus ensure that the heat transfer effect of solar energy system, and 90 more than % are reached to the inhibition efficiency of aluminium alloy and carbon steel, 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;
