Abstract
The utility model discloses a kind of composite coatings for corrosion of steel structure position rapid-maintenance, including aqueous rust conversion coating, water-base epoxy coating, Aqueous acrylic urethane's coating, the surface of the steel construction is respectively Aqueous acrylic urethane's coating, water-base epoxy coating, aqueous rust conversion coating from top to bottom, and the aqueous rust conversion coating is applied directly to steel construction rusty surface.The composite coating of the utility model is simple; construction is easy; and it joined rust transforming agent in aqueous rust conversion coating; it can be reacted with iron rust and generate complex compound; the adhesive force for improving coating is conducive to the steel construction of protection corrosion, prevents corrosion position from further corroding; the maintenance difficulty for greatly alleviating steel construction corrosion position, improves the service life of steel construction.
Description
Technical field
The utility model belongs to coatings art, and in particular to a kind of for the aqueous multiple of corrosion of steel structure position rapid-maintenance
Close coating.
Background technique
There is the utilization of a large amount of steel constructions in various industries field, although steel structure surface would generally carry out spray painting in advance and prevent
Shield, but long-term environmental corrosion can make steel structure surface corrosion defect occur, expose to the sun and rain, oxidation corrosion, corrosion-inhibiting coating is very
The aging phenomena such as it is easy to happen cracking, peeling, falls off, these corrosion positions are if necessary to maintenance spray painting again, before spray painting,
It first has to derust to surface, to improve the adhesive force of paint film, also needs to carry out sandblasting to metal foundation after the completion of derusting to beat
Mill, then could paint again, and the entire pretreatment procedure that paints takes time and effort, and can generate dust and noise pollution, and can not be thorough
The corrosion at complex job face dead angle is removed at bottom, in addition, the problems such as also will cause thinned steel construction, strength reduction, in addition in part
Under environment, also lacks equipment and condition carries out perfect pre-treatment.
Summary of the invention
To solve the above-mentioned problems, the purpose of this utility model is to provide one kind quickly ties up for corrosion of steel structure position
The aqueous composite coating repaired, the utility model are realized by using following technical scheme:
A kind of aqueous composite coating for the maintenance of corrosion of steel structure position rapid-maintenance, including aqueous rust conversion coating,
Water-base epoxy coating, Aqueous acrylic urethane's coating, the rusty surface of steel construction are respectively that aqueous rust conversion applies from top to bottom
Layer, water-base epoxy coating, Aqueous acrylic urethane's coating.
Preferably, it is described it is aqueous rust conversion coating be using water-base resin as film forming matter, addition rust transforming agent aqueous coating,
With a thickness of 40-80 microns.
Preferably, the water-base epoxy coating is using aqueous epoxy resins as the aqueous coating of film forming matter, with a thickness of 30-50
Micron.
Preferably, Aqueous acrylic urethane's coating be using water-based acrylic resin as the aqueous coating of film forming matter,
With a thickness of 30-50 microns.
Compared with prior art, the utility model has the beneficial effects that: the aqueous composite coating is simple, construction is easy,
It joined rust transforming agent in aqueous rust conversion coating, improve the transformation efficiency of iron rust, before reducing derusting, sandblasting polishing etc.
Link is managed, the coating maintenance difficulty and environmental pollution at steel construction corrosion position is reduced, maintenance efficiency greatly improved.
Detailed description of the invention
Fig. 1 is a kind of aqueous composite coating schematic diagram for corrosion of steel structure position rapid-maintenance of the utility model.
Specific embodiment
With reference to the accompanying drawing and specific embodiment, the utility model is described further:
As shown in Figure 1, a kind of aqueous coating for corrosion of steel structure position rapid-maintenance of the utility model, including steel
Form substrate 4, Aqueous acrylic urethane's coating 1, water-base epoxy coating 2 and aqueous rust conversion coating 3, the surface of the substrate
It is from top to bottom respectively Aqueous acrylic urethane's coating 1, water-base epoxy coating 2 and aqueous rust conversion coating 3, the aqueous ring
Oxygen coating 2 is bonded in the surface of aqueous rust conversion coating 3 on one side, and another side is bonded in the table of Aqueous acrylic urethane's coating 1
Face.
The aqueous rust conversion coating 3 has extremely strong rust conversion capability, can be by the rust transformation of metallic substrate surface
For complex compound, while there is very high adhesive force with substrate.
Water-base epoxy coating 2 has good corrosion resistance, can prevent the corrosion again of substrate, paint film has good machine
Tool performance and ply adhesion.
Aqueous acrylic urethane's coating 1 has good weather resistance, and ultraviolet light and water can be prevented to break coating
It is bad, and with outstanding appearance and decoration ability.
The aqueous rust conversion coating of the utility model uses aqueous acrylic emulsion, waterborne styrene-acrylic emulsion or aqueous chloroethene
Alkenyl lotion is film forming matter, is rust transforming agent with tannic acid, phosphoric acid, benzoic acid, adds dispersing agent, defoaming agent, levelling agent, increasing
Thick dose is prepared, and has very strong rust conversion capability, can be complex compound by rust transformation, can be widely used for steel construction corrosion
The rapid-maintenance on surface.
The above is only the preferred embodiment of the utility model, but this patent is not limited to the above embodiment,
It can also make several improvements without departing from the principle of this utility model, these improvement also should be regarded as the utility model
Protection scope.
