Description

{The method of forming the protective film on the metallic decorative panel for building}

The present invention relates to a method for forming a film of a decorative metal plate for building, and more particularly, to a specific portion of a decorative plate of metal by a resin electrodeposition method using a water support solution in which a urethane acrylic material and an ionization activating material are mixed. It relates to a method for forming a protective film of a decorative metal plate for building to form a.

In general, various beautiful patterns are formed and plated on metal plates such as stainless plates or copper plates (hereinafter referred to as metal plates) for the purpose of beautifully decorating the interior of elevator cages, doors, or buildings, and work such as corrosion and scratching. It forms a pattern and is used as decoration material of various buildings.

  As an example, as shown in FIG. 1, a process of manufacturing a beautiful decorative metal decorative plate by etching a plurality of portions of a metal plate to form a specific pattern shape and plating gold on the surface of the pattern shape, first, in FIG. As described above, a first masking ink is applied to a portion of the metal plate 1 except for a specific pattern to be formed on the metal plate 1 such as stainless steel.

  Then, the surface of the metal plate 1 is etched while the first masking ink 2 is applied, and then the first masking ink 2 is dissolved and removed with hydrogen peroxide. As shown in FIG. 1 (c) in order to plate gold on the etching part 3, the etching part 3 to be formed is etched by the part to which the first masking ink 2 is not applied is etched. As in the second masking ink 4 is applied to the surface of the metal plate 1 of the remaining portion except the etching portion (3).

  Thereafter, as shown in (d) of FIG. 1, the metal plate 1 coated with the second masking ink 4 is added to a gold plating apparatus to complete plating, and then the second masking ink 4 is dissolved in a diluent. When the removal and washing by the gold deposition portion 5 is formed in a thin pattern of several microns on the surface of the etching pattern 3, that is, the pattern formed on the metal plate 1, as shown in (e) of FIG. The production of beautiful architectural metal plate is completed.

However, the appearance of the decorative metal plate for building manufactured by such a process becomes beautiful, but it is not only difficult to remove when foreign matter such as dust gets on the gold deposit, but also when removing foreign matter on the surface of the plating or when a long time elapses. The gold deposit formed on the metal decorative plate may be damaged or separated from the metal plate, which may adversely affect the appearance, resulting in a shortened lifespan.

According to the present invention, a protective layer is formed on a surface of a specific portion such as a gold deposition portion of a metal decorative plate by a resin electrodeposition method using a water support liquid containing a urethane acrylic material and an ionization-activating material. It is an object of the present invention to provide a method for forming a protective coating on a decorative plate of building metal, which can be easily removed when the same foreign material is applied, and also has a semi-permanent life by preventing the gold deposit from being damaged or separated from the metal plate. .

The present invention is a decorative metal decorative plate for forming a specific pattern by etching a plurality of parts of the metal plate, the step of applying masking ink to the remaining portions other than the specific portion to form a protective film of the metal plate, the masking ink is applied Injecting the prepared metal plate into the film forming apparatus in which the coating stock solution is embedded, and applying a different electrode to the coating stock solution and the metal plate, respectively, and electrodepositing resin on the masking ink opened by ionization to form a protective film. Separating and washing the metal plate from the film forming apparatus and heat-treating at 150 for about 2 hours, after which the entire surface of the metal plate is dissolved with a diluent to remove the masking ink applied to the metal plate. .

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a structural diagram of a protective film forming apparatus for forming a protective film on the surface of the gold deposition section 5 plated on the etching plate 3 of the metal plate 1 of a building metal decorative plate. When the water support liquid and ultrapure water mixed with urethane acrylic material and ionization activating material are mixed in a predetermined ratio, the ionization phenomenon is divided into anions by receiving molecular or valence energy after the water support liquid is dissolved in the ultra pure water. Will be displayed.

  In this state, a process of forming a protective film on a specific portion such as a gold plating layer of a building metal decorative plate manufactured by the same process as in FIG. 1 through FIGS. 3 to 6 will be described.

  In order to form a protective film on the surface of the gold deposition portion 5 plated on the etching plate 3 of the metal plate 1 of the building metal decorative plate manufactured by the same process as in FIG. The third masking ink 9 is applied to the metal plate 1 of the remaining portions except for the etching portion 3 in which (5) is formed.

 Then, as shown in FIG. 4, the metal plate 1 coated with the third masking ink 9 is introduced into the protective film forming apparatus 7, and then the power solution 8 is dissolved in ultrapure water. When applied to 1), an ionization phenomenon occurs in which the resin solution is divided into ions.

  Therefore, the resin solution is not deposited on the third masking ink 9 applied to the metal plate 1, as shown in FIG. 5, but the protective film 10 is formed to a thickness of several microns by resin electrodeposition only on the open gold deposition unit 5. ) Is formed, after which the metal plate (1) is separated from the protective film forming apparatus (7), washed, and then heat treated at 150 for about 2 hours to maintain a predetermined strength (about 4H). The protective film 10 becomes insoluble.

  After the above process is completed, the entire surface of the metal plate 1 is dissolved with a diluent, and as shown in FIG. 6, the third masking ink 9 applied to the metal plate 1 is removed and the resin is electrodeposited, a transparent colorless protective film. Only (10) is left to protect the gold deposition unit (5) where the urethane acrylic material and the ion support material mixed with the water support liquid and ultrapure water when the desired color is added to the desired color treatment is possible gold It is possible to form a protective film on a specific portion of the plating layer, it is possible to maintain the cleanness of the decorative metal decorative plate, as well as the color treatment by depositing a protective film on the front or part of the metal plate.
