In prior art, in order to be obtained the galvanized steel plain sheet of coloured appearance by passivation procedure, adopt method galvanized steel plain sheet being applied colored trivalent chromium passivating film, but trivalent chromium is easily converted into Cr VI more, there is problem not environmentally.
Summary of the invention
The utility model solves chromatic passivation galvanized steel plain sheet of the prior art by providing a kind of completely without chromium passivating colored zinc plated steel, there is technical problem not environmentally.
The utility model provides a kind of completely without chromium passivating colored zinc plated steel, comprising:
Galvanized steel plain sheet;
Colored completely without chromium passivation film, cover 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, described colour completely without the scope of the thickness of chromium passivation film is: 0.5 micron ~ 5 microns.
The utility model at least has following technique effect or advantage:
The utility model discloses a kind of completely without chromium passivating colored zinc plated steel, adopt the full chromium-free passivation liquid being mixed with dyestuff, thin and the colour of densification of one deck is formed completely without chromium passivation film at galvanized steel sheet surface, galvanized steel plain sheet can not only be made to have colorful color, and have bright in luster, not easily fade, the advantage such as good decorative property, environmental protection, corrosion resistance are strong.
Accompanying drawing explanation
Fig. 1 is the structural representation completely without chromium passivating colored zinc plated steel in the utility model embodiment.
Detailed description of the invention
The utility model embodiment solves chromatic passivation galvanized steel plain sheet of the prior art by providing a kind of completely without chromium passivating colored zinc plated steel and manufacture method thereof, there is technical problem not environmentally.
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 completely without chromium passivating colored zinc plated steel, comprising:
Galvanized steel plain sheet 201;
Colored completely without chromium passivation film 202, be coated in described galvanized steel plain sheet 201 surface.
In specific implementation process, described colour completely without chromium passivation film 202 can be: blue or red or green or brown etc. random color, for the pigment of described colour completely without chromium passivation film, the present embodiment does not do concrete restriction.
Optionally, in the present embodiment, described galvanized steel plain sheet 201 is specially: hot-dip galvanizing sheet steel, or plated steel sheet.
Optionally, in the present embodiment, the scope of the thickness of described galvanized steel plain sheet 201 is: 0.3 millimeter ~ 2.5 millimeters.
Optionally, in the present embodiment, described colour completely without the scope of the thickness of chromium passivation film 202 is: 0.5 micron ~ 5 microns.
Further, provide the above-mentioned manufacture method completely without chromium passivating colored zinc plated steel, comprising:
Be dissolved in by dyestuff in full chromium-free passivation liquid, described full chromium-free passivation liquid is not containing chromium;
The full chromium-free passivation liquid being dissolved with dyestuff is coated in galvanized steel plain sheet 201 surface;
