Description

  The present invention relates to a metal member having an abraded pattern and a method of manufacturing the same, and more particularly, to a metal member having an abraded pattern on which a clear contrast is produced on a metal surface and a texture derived from a metal substrate can be easily viewed. It relates to the manufacturing method.

  In construction materials, metal plates, particularly steel plates, are often used as highly rigid materials. In particular, building materials used outdoors are required to have high corrosion resistance to acids, moisture and the like because they are exposed to the outdoors for a long time.

On the other hand, the method of providing corrosion resistance to a steel plate by coating is known. This is to form a coating having corrosion resistance as a coating on the surface of a steel plate, and it is necessary to form a coating sufficient to exhibit functionality.
A highly corrosion-resistant plated steel sheet is known as a material that imparts high corrosion resistance to the steel sheet itself. This is a steel plate plated with an alloy.

  On the other hand, while decorative materials are required for building materials used for interiors and exteriors, patterns are given to steel plates by coloring or polishing.

  Here, it is difficult to apply surface processing to the above-described high corrosion resistance plated steel sheet, and it is difficult to apply processing to impart decorativeness.

On the other hand, a method is known in which a hot dip galvanized steel material is subjected to a phosphating treatment and then treated with a black dyeing agent to black dye the hot dip galvanized steel material (for example, Patent Document 1).
Moreover, the technique of the powder coating which colors a highly corrosion-resistant plated steel plate with a powder-form coating material is used (for example, patent document 2).

  Furthermore, melting is provided with a hot-dip Zn-based plating layer provided on the surface of a steel plate, and a black layer containing an oxide and / or a hydroxide formed by steam treatment on the surface layer of the hot-dip Zn-based plating layer There is known a hot-dip galvanized steel sheet having a linear pattern on a zinc-based plated steel sheet (for example, Patent Document 3).

Patent No. 4980607 Patent No. 3926270 gazette JP, 2017-218647, A

The technology of Patent Document 1 is limited to the pattern of the surface on the spangle. Furthermore, after processing, white rust occurs in the hot-dip galvanized steel material, and the performance as a building material decreases.
Moreover, although the above-mentioned spangle pattern has a designability, in addition to the design being limited to the pattern, it may be difficult to control the finish.

  On the other hand, although powder coating like Patent Document 2 has a high degree of color freedom, the whole of the high corrosion resistance plated steel plate becomes the texture of the powder coating, and only the texture different from the texture of the metal itself can appear.

In the case of forming a pattern by polishing, there is a problem that depending on the type of metal and the coloration of the surface, the polished pattern can not be clearly seen and the texture unique to the metal is lost.
In addition, when the high corrosion resistance plated steel plate is used without being subjected to finish processing, the color number of the steel plate is limited to a dull silver color, and the range of use as a building finish is greatly narrowed.

  In order to form the film of an oxide and / or a hydroxide by steam processing and to grind | polish this, the hot-dip Zn type steel plate of patent document 3 requires the installation for performing steam processing. Also, if the amount of oxide or hydroxide film formed is small, it is difficult to polish, and if it is large, the film will fall off at one time, so it is difficult to apply the desired pattern by polishing, and the processability There is a problem with
