Description
Technical field
The present invention relates to protection agent, in particular to a kind of resistance to dust storm mill coating naked steel surface
Erosion agent and preparation method thereof.
Background technology
Metal erosion is the metal a kind of failure procedure under environmental corrosion medium effect, is metallurgical
The inverse process produced, entropy is continuously increased, be a kind of the most spontaneous carry out inevitable the most naturally show
As.Atmospheric corrosion causes the initial failures such as product, unit, structural member and destruction
Major reason.The economic loss caused because of atmospheric corrosion every year is the most surprising.
Under air natural environment, it is a step-by-step procedure that naked steel forms stable protection rusty scale, needs
Wanting considerable time, at least need more than 3 years, the naked steel surface having forms form compact and stable rust
The time of layer was more than more than 10 years.During wind sand environment forms stable rusty scale, usually
Occur that rust liquid stream is hung and the caducous phenomenon of rusty scale in early days.
The most also there is no a kind of effective abradant of resistance to dust storm at present, so in the urgent need to one
The abradant of resistance to dust storm.
Summary of the invention
The present invention is directed to naked steel and hang ask easy to fall off with rusty scale at the naked steel of wind sand environment rust liquid stream in early days
Topic, it is provided that a kind of abradant of resistance to dust storm coating naked steel surface and preparation method thereof；This resistive
Husky abradant is that naked steel surface is carried out chemical treatment, directly generates the rusty scale of stable densification, shape
Become self-protection.After coating the abradant of resistance to dust storm, naked steel both can be avoided to use initial stage yellow rust liquid
The phenomenon of sagging, can quickly form again stable protective rust on its surface, prevents rusty scale from taking off
Fall, make the corrosion rate of naked steel tend towards stability.
For achieving the above object, a kind of resistance to windsand mill corrosion coating naked steel surface that the present invention provides

FePO4Being deposited on steel substrate surface, form fine and close, complete rusty scale, corrosion resistance is strong.
FeCl3As corrosive chemical.Cl-It is penetrant particle, accelerates the corrosion of steel.
Fe3+It is high valence ion, Fe can be generated with base steel generation Quick Oxidation reduction reaction2+Ion.
Copper sulfate promotes the amorphous Fe of surface corrosion layer3O4Generate mutually, it addition, copper plays activation
The effect of negative electrode, promotes steel anode to be passivated, slows down corrosion.
Calcium nitrate and phosphate generation precipitation, generate insoluble calcium phosphate, be deposited on steel
On primary surface, make rusty scale finer and close, complete, improve corrosion resistance and wearability.
The addition of nickel nitrate makes nickel be enriched with in rusty scale, and base steel inner surface can produce one layer of thin richness
Collecting layer, this rusty scale is close to the internal layer of steel matrix, and tack is strong, promotes steel anode to be passivated,
Corrosive medium can be slowed down corrode further inside steel plate.
As the film forming component in solution during tannic acid coating, there is preferable passivation effect.
The beneficial effects of the present invention is:
