Description
Technical field
The present invention relates to a kind of rust and process material, promote rust inactivation transforming agent in particular to one.
Background technology
Steel component is in atmospheric environment, easily corrodes, and causes economic loss.Application
Anticorrosive paint can increase the service life of steel beam column greatly.In order to obtain excellent corrosion resistance
Can, steel beam column Surface Rust must be removed clean before application, otherwise paint film can due to rust not
Disconnected expansion causes paint to come off.Manually eliminate rust not only complex operation, time and effort consuming, also has certain
Danger, the mode such as sandblasting, hydroblasting there is also respective shortcoming, it is impossible to replace people
Work rust cleaning mode.Using chemical treatment is dense inert layer by rust transformation, reduces artificial rust cleaning
Workload, thus reach antiseptical effect, be the most feasible a kind of mode.
In currently available technology, rust remover or antirust agent etc. are occurred in that, this series products master
Mineral acid to be passed through, to the dissolving of rusty scale and reaction, reaches the effect of rust cleaning, and uses similar phosphorus
Change the composition of liquid, form phosphate coating in metal surface, play antirust effect.But this kind of rust cleaning
Antirust agent self contains the mineral acids such as larger amount of hydrochloric acid, phosphoric acid, has bigger corruption to steel
Erosion, easily makes metal produce hydrogen embrittlement；It addition, this product is uncontrollable with the reaction rate of rusty scale,
Easily cause reaction not exclusively.Additionally, processed metal interface complicated component, with follow-up
The adhesion of anticorrosive paint is relatively poor, reduces the service life of anticorrosive paint.Publication No.
The Chinese patent of CN102071414A provides a kind of rust conversion and rust-proof coating agent, and it is by coating
The removing of rust, greasy dirt is realized at band rust steel surface.But its shortcoming be mineral acid acid content relatively
Height, produces gas after the material of residual and metal reaction, easily causes coating foaming.Publication number
A kind of derusting rust-proofing conversion film treating agent is disclosed for CN102071414A Chinese patent, will
On this direct steel surface of derusting rust-proofing conversion film treating agent, to remove steel surface rust, and
Form the conversion protecting film that one layer of compactness is high, but its shortcoming be that rusty scale thickness is had strict demand,
Rusty scale is poor compared with thick material treatment effect, and rusty scale is relatively thin, base material can be caused acid corrosion.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, the object of the invention aims to provide a kind of rust inactivation that promotees and turns
Agent, this transforming agent can control the metal ion content in solution by buffer system, thus
Control itself and rusty scale conversion reaction, it is ensured that rusty scale can convert and be formed inertia protective layer completely,
Steel substrate will not be caused corrosion.In addition the adhesion of base material and corrosion-inhibiting coating can also effectively be promoted,
Ensure the service life of coating.
Realize the object of the invention and the technical scheme is that a kind of rust that promotees inactivates transforming agent, including:
The water of 58%-68%, the phosphoric acid of 8%-15%, 2%-5% oxalic acid, 5%-10% rush rust deactivator,
The rusty scale wetting agent of 10%-20%, the reaction controlling agent of 5%-15%, 1%-5% metal inhibitor,
The interface coupling agent of 0.5%-5%, the surfactant of 0.5%-5%, above percentage ratio is quality
Percentage ratio.
In technique scheme, promoting rust inactivation transforming agent is gallic acid；Rusty scale wetting agent
For neopentyl alcohol and any one or two kinds of sums of the tert-butyl alcohol；Reaction controlling agent be sodium citrate and/or
Sulfosalicylic acid sodium salt；Interface coupling agent is aminopropyl triethoxysilane, and metal inhibitor is sulfur
Urea and/or hexamethylenamine；Surfactant is dodecylbenzene sodium sulfonate and/or op-10.
Transforming agent of the present invention utilizes faintly acid and the reproducibility of gallic acid, forms acidity with phosphoric acid
Buffer system, can control the iron ion content in rusty scale, the oxidation of suppression metallic iron, thus reach
To the purpose controlling rusty scale reaction rate；Gallic acid can form stable chela with metal ion simultaneously
Compound, it is thus possible to cover on rusty scale surface with network molecular structure, it is ensured that rusty scale can turn completely
Change and formed inertia protective layer.It addition, add metal inhibitor in the present invention, it is ensured that nothing
Steel substrate will not be caused corrosion by machine acid, thus avoids the generation of Hydrogen Brittleness Phenomena.Additionally, convert
Coupling agent in agent can play the effect connecting substrate surface with corrosion-inhibiting coating, can effectively promote base
Material and the adhesion of corrosion-inhibiting coating, it is ensured that the service life of coating.
Compared with prior art, the invention have the advantages that
1, use buffer system, control rusty scale reaction rate, it is ensured that rusty scale converts completely；
2, metal inhibitor is used, little to base material corrosion；
3, use interface coupling agent, increase the adhesive force of base material and corrosion-inhibiting coating；
4, VOC free, environmentally friendly.
