Description
Technical field
The utility model relates to iron and steel manufacturing technology field, particularly relates to a kind of colored zinc plated steel of resistance to fingerprint.
Background technology
Galvanized steel plain sheet is widely used in the industrial circles such as building materials, household electrical appliances, automobile, by applying zinc coat as negative electrode sacrificial protective layer on general steel plate surface, can strengthen the decay resistance of general steel plate.
Colored zinc plated steel is not changing on the basis of its mechanical characteristic, makes galvanized steel plain sheet have outward appearance that is bright-colored, uniform in color, thus has ornamental preferably.
In prior art, in order to be obtained the galvanized steel plain sheet of coloured appearance by passivation procedure, galvanized steel plain sheet is applied the method for colored trivalent chromium passivating film by many employings, but the chromatic passivation galvanized steel plain sheet that this method is produced, pigment is combined not tight with the zinc coat of steel plate, there is the problem easily faded, and trivalent chromium is easily converted into Cr VI, not environmentally.
Summary of the invention
The utility model, by providing a kind of colored zinc plated steel of resistance to fingerprint, solves chromatic passivation galvanized steel plain sheet of the prior art, there is the technical problem easily faded.
The utility model provides a kind of colored zinc plated steel of resistance to fingerprint, comprising:
Galvanized steel plain sheet;
Color fingerprint resistant passivating film, covers described galvanized steel sheet surface.
Preferably, described galvanized steel plain sheet is specially: hot-dip galvanizing sheet steel, or plated steel sheet.
Preferably, the scope of the thickness of described galvanized steel plain sheet is: 0.3 millimeter ~ 2.5 millimeters.
Preferably, the scope of the thickness of described color fingerprint resistant passivating film is: 0.5 micron ~ 5 microns.
The utility model at least has following technique effect or advantage:
The colored zinc plated steel of resistance to fingerprint in the utility model, adopt the passivating solution of resistance to fingerprint being mixed with dyestuff, thin and the color fingerprint resistant passivating film of densification of one deck is formed at galvanized steel sheet surface, pigment is combined closely with the zinc coat of galvanized steel plain sheet, have bright in luster, color evenly, not easily fades, environmental protection, resistance to fingerprint, the advantage such as corrosion-resistant.
Accompanying drawing explanation
Fig. 1 is the structural representation of the colored zinc plated steel of resistance to fingerprint in the utility model embodiment.
Detailed description of the invention
The utility model embodiment, by providing a kind of colored zinc plated steel of resistance to fingerprint and manufacture method thereof, solves chromatic passivation galvanized steel plain sheet of the prior art, there is the technical problem easily faded.
In order to better understand technique scheme, below in conjunction with Figure of description and concrete embodiment, technique scheme is described in detail.
Embodiment one
As shown in Figure 1, the present embodiment provides a kind of colored zinc plated steel of resistance to fingerprint, comprising:

In specific implementation process, described dyestuff can be: blue or red or green or brown etc. random color, and for the pigment of described dyestuff specifically which kind of color, the present embodiment does not do concrete restriction.
In specific implementation process, need according to the color of colored zinc plated steel, the passivating solution of resistance to fingerprint configured is mixed a certain proportion of dyestuff, and with mixer by the passivating solution of resistance to fingerprint and dyestuff mixing, then rolling method is adopted at normal temperatures the passivating solution of resistance to fingerprint of mixed dye to be coated in the surface of galvanized steel plain sheet.
In specific implementation process, after the color that galvanized steel plain sheet presents dyestuff, finely tuned by the color of thickness to galvanized steel sheet surface of adjustment color fingerprint resistant passivating film, particularly, can be adjusted by the pressure between the application roll of adjustment roll coater and galvanized steel plain sheet and the thickness of rotating ratio to color fingerprint resistant passivating film between application roll and galvanized steel plain sheet.
Optionally, in the present embodiment, described galvanized steel plain sheet can be: hot-dip galvanizing sheet steel, or plated steel sheet.
Optionally, in the present embodiment, the described passivating solution of resistance to fingerprint to described galvanized steel sheet surface processes, and to form color fingerprint resistant passivating film at described galvanized steel sheet surface, comprising:
Galvanized steel plain sheet after passivation is placed in air flow dryer, drying and solidification are carried out to the passivating solution of resistance to fingerprint of galvanized steel sheet surface, to form color fingerprint resistant passivating film at described Several Thiourea Derivatives on Zinc Plate Surface, wherein, the temperature range of described drying and solidification is: 130 DEG C ~ 160 DEG C.
Technical scheme in above-mentioned the utility model embodiment, at least has following technique effect or advantage:
The colored zinc plated steel of resistance to fingerprint in the utility model, adopt the passivating solution of resistance to fingerprint being mixed with dyestuff, thin and the color fingerprint resistant passivating film of densification of one deck is formed at galvanized steel sheet surface, pigment is combined closely with the zinc coat of galvanized steel plain sheet, have bright in luster, color evenly, not easily fades, environmental protection, resistance to fingerprint, the advantage such as corrosion-resistant.
Although described preferred embodiment of the present utility model, those skilled in the art once obtain the basic creative concept of cicada, then can make other change and amendment to these embodiments.So claims are intended to be interpreted as comprising preferred embodiment and falling into all changes and the amendment of the utility model scope.
