Description of the Related Art Zinc-based plated steel sheets include low carbon cold-rolled steel sheets, plain steel sheets such as hot-rolled steel sheets, or chromium-containing steel sheets such as stainless steel sheets, etc., which are used for hot dipping or electroplating. It is manufactured by plating zinc or zinc alloy by vapor deposition plating method,
When blackening these steel sheets to enhance their design, a method of forming a black zinc phosphate coating by treating the steel sheets with a zinc phosphate treatment agent is adopted in place of the general coating method. (Japanese Patent Application No. 5-181883 and Japanese Patent Application Laid-Open No. 5-237450).

ラになってしまうという問題もあった。However, the zinc phosphate coating is porous and inferior in corrosion resistance, and the coating is damaged during the molding process, so that the zinc phosphate coating cannot be used as a building material as it is. As a countermeasure for this, a method of protecting the zinc phosphate film by forming a chromate film by chromate treatment after zinc phosphate treatment and further forming a clear resin coating film on it is conceivable. Even if only the clear resin coating film was formed, the glossiness of the coating film was high, and therefore the color tone changed depending on the viewing angle, and the uniform appearance was not obtained. Also, if the clear resin coating film is made of resin alone, the corrosion resistance is poor,
If it is used in the coastal area where sea salt particles etc. are affected, it will reach the zinc phosphate film in a short time. Furthermore, when the zinc phosphate coating is formed on a continuous line, a slight color difference occurs in the longitudinal direction and width direction of the coil, but this color difference is emphasized when a clear resin coating with high gloss is formed. There was also the problem of unevenness.

０.２％と着色顔料を０.０２〜０.１％とを添加した。According to the present invention, 4 to 13% of an extender pigment is added to a clear resin coating film. In addition to the extender pigment, 0.04 to 0.2% of rust preventive pigment or 0.04 to rust preventive pigment is added to the clear resin coating film of the blackened zinc-based plated steel sheet.
0.2% and 0.02-0.1% of color pigments were added.

カ粉末が好ましい。When the extender pigment is added to the clear resin coating film, the gloss of the coating film is lowered, and the color tone does not change depending on the viewing angle. The extender pigment is preferably added so that the glossiness becomes 3 to 10, and for that purpose, it is made to be 4 to 13% of the coating film. When it is less than 4%, the glossiness exceeds 10,
The gloss becomes high, and even if the amount exceeds 13%, the gloss is not further reduced. As the extender pigment, powders of magnesium carbonate, white carbon, silica and the like, particularly silica powders are preferable.

る。However, only by adding the extender pigment, the corrosion resistance of the coating film was insufficient, and a slight color difference generated in the longitudinal direction and the width direction of the coil was emphasized. Therefore, a color pigment is added to the coating film, or a color pigment together with the rust prevention pigment. That is, when a rust preventive pigment is added, the corrosion resistance becomes high, so even if sea salt particles or the like adhere, the zinc phosphate film cannot be easily reached, and both the rust preventive pigment and the coloring pigment are added. In addition to corrosion resistance, a slight difference in color tone that occurs in the longitudinal direction and width direction of the coil is reduced.

−ボンブラックが好ましい。The amount of the rust preventive pigment added is 0.04 to 0.2%. This is because if it is less than 0.04%, the corrosion resistance is not improved, and if it is more than 0.2%, no further effect of improving the corrosion resistance is recognized. Ammonium chromate, magnesium chromate, nickel chromate, strontium chromate and the like are suitable as the rust preventive pigment. Further, the addition amount of the coloring pigment is 0.02 to 0.1%. 0.
If it is less than 02%, it is difficult to reduce the color difference, and the difference is 0.1.
%, The color tone of black gray obtained by the zinc phosphate coating is impaired, resulting in poor design. The coloring pigment may be either an inorganic pigment or an organic pigment, but carbon black having excellent weather resistance and chemical resistance is preferable.

If it is less than 3 μm, the zinc phosphate film peeling during molding cannot be sufficiently suppressed and the corrosion resistance is lowered, and if it exceeds 15 μm, the coating film peeling may occur during molding.

Zinc phosphate film, chromate film with chromic anhydride (total chromium amount: 10 mg / m
After forming 2 ), a clear coat containing polyester resin as a main component was coated with a roll coater so that the dry coating film thickness was 10 μm, and was baked and dried. As the clear paint, not only the extender pigment (silica powder) but also the rust preventive pigment (strontium chromate) and the coloring pigment (carbon black) were used. Then, the following tests were carried out after the coating of each paint was completed. Table 1 shows the coating composition, and Table 2 shows the test results.

Further, even if the zinc phosphate coating is formed on a continuous line, there is no difference in color tone in the longitudinal direction and width direction of the coil.
