Abstract
The utility model discloses a kind of graphene heavy antisepsis composite coatings for steel structure bridge coating, including painting, acrylic polyurethane finish paint in graphene heavy antisepsis priming paint, epoxy micaceous iron, the surface of the steel structure bridge is respectively graphene heavy antisepsis priming paint, applies in epoxy micaceous iron, acrylic polyurethane finish paint from top to bottom, and the graphene heavy antisepsis priming paint is applied directly to steel structure surface.The coating structure of the utility model is simple, construction is easy, anti-corrosion capability is excellent, with long-effective corrosion weather resistance, steel structure bridge coating applied widely, especially under adverse circumstances, can significantly reduce the corrosion of steel structure bridge, reduce coating maintenance frequency, the service life of lifting steel structural bridge.
Description
Technical field
The utility model belongs to coatings art, and in particular to a kind of graphene heavy antisepsis for steel structure bridge coating is multiple
Close coating.
Background technique
The application of steel structure bridge is typically all in the stronger environment of corrosivity, and chronic sun exposure drenches with rain, oxidation corrosion, steel
The mechanical performances such as its intensity, toughness can be greatly reduced after structure erosion, are seriously endangered bridge security, are brought huge security risk.
Traditional corrosion-inhibiting coating is easy to that cracking, aging, peeling, phenomena such as falling off occurs in harsh environment, protects the time limit short, need through
Repairing work often is carried out to coating, and can greatly reduce the service life of steel structure bridge after breakdown of coating.
Summary of the invention
To solve the above-mentioned problems, the purpose of this utility model is to provide a kind of graphite for steel structure bridge coating
Alkene heavy antisepsis composite coating, the purpose of this utility model are implemented with the following technical solutions:
A kind of graphene heavy antisepsis composite coating for steel structure bridge coating, including graphene heavy antisepsis priming paint, ring
Oxygen Yun Tiezhong painting, acrylic polyurethane finish paint, steel structure bridge surface are respectively graphene heavy antisepsis priming paint, epoxy from top to bottom
Yun Tiezhong painting, acrylic polyurethane finish paint.
Preferably, the graphene heavy antisepsis priming paint is using epoxy resin as film forming matter, addition graphene slurry, anticorrosion
The coating of pigment, auxiliary agent, with a thickness of 60-100 microns.
Preferably, the coating using epoxy resin as film forming matter is painted in the epoxy micaceous iron, with a thickness of 50-70 microns.
Preferably, the acrylic polyurethane finish paint be using acrylic resin as the coating of film forming matter, it is micro- with a thickness of 60-80
Rice.
Compared with prior art, the utility model has the beneficial effects that: the graphene anticorrosion coat structure, construction are held
Easily, graphene slurry and zinc powder be joined in graphene heavy antisepsis priming paint, the Corrosion Protection of coating can be greatly improved, had
There is extremely strong durability, improves the service life of steel structure bridge.
Detailed description of the invention
Fig. 1 is a kind of graphene heavy antisepsis composite coating schematic diagram for steel structure bridge coating 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 graphene heavy antisepsis composite coating for steel structure bridge coating of the utility model, packet
Steel construction substrate 4, acrylic polyurethane finish paint layer 1, epoxy micaceous iron floating coat 2 and the graphene heavy antisepsis priming paint bed of material 3 are included, it is described
The surface of substrate is respectively acrylic polyurethane finish paint layer 1, epoxy micaceous iron floating coat 2 and graphene heavy antisepsis priming paint from top to bottom
The bed of material 3, the epoxy micaceous iron floating coat 2 are bonded in the surface of the graphene heavy antisepsis priming paint bed of material 3 on one side, and another side is bonded in third
The surface of olefin(e) acid polyurethane finish layer 1.
The graphene heavy antisepsis priming paint bed of material 3 has extremely strong anti-corrosion capability, while with substrate with very high attached
Put forth effort.
The epoxy micaceous iron floating coat 2 has good impermeable ability, and extraneous moisture content can be prevented to coat inside
Infiltration, paint film have good mechanical performance and ply adhesion.
The acrylic polyurethane finish paint layer 1 has good weather resistance, and ultraviolet light and water can be prevented to coating
It destroys, and with outstanding appearance and decoration ability.
The graphene heavy antisepsis priming paint of the utility model is used using epoxy resin as film forming matter, adds graphene slurry, zinc
Powder, corrosion-inhibiting pigment, auxiliary agent are prepared, and the graphene in paint film is a kind of lamellar nanostructure powder, can effectively hinder
Only infiltration of the corrosive substance to substrate, while graphene and zinc powder constitute " zinc-alkene " structure, have very strong electrochemical anti-corrosive
Erosion ability can be widely used for the coating of steel structure bridge.
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.
