Abstract

A metal plate is lacquered with nacre to give a decorative metal plate which is florid and graceful. Then metal plate is ground with sandpaper to give roughness on the metal surface. The rough metal plate is lacquered, and then is heated at 100-200 ≰C for 10-20 mins. This step is repeated three times, and then lacquered metal is ground again, and then nacre is applied to the plate. This plate is lacquered again and then is heated to give the final product.

The present invention relates to a method for producing a decorative plate barely coated on a metal plate, in particular, a thin metal plate, and in particular, the present invention enables a metal plate on a thin metal plate which is almost impossible to be barely coated, and thus has excellent decorativeness or splendor. It is to provide a decorative plate.

In general, Najeon Lacquerware is widely known as a unique craft of our country, and this Najeon Lacquerware has a gorgeous and elegant harmony with lacquer that shows black or red color by its brilliant color and luster. It is a well-known fact that it is a craft that is excellent in splendor.

However, despite the splendid decoration of Najeon Lacquerware, the decoration of Najeon and Lacquer is limited only to wooden products due to the monotonous problem of the choice of the base material which is generally limited to wood only. There was a problem that can not be diversified.

Therefore, the conventional method of performing Najeon and lacquer at the same time has been tried several times, but this is simply provided with a method that can be partially carried out in the synthetic resin, it is mainly used as various decorative plates due to the excellent rigidity and durability of the material It was not possible to carry out the diversification of the decorative plate on the metal plate, and the synthetic resin itself was vulnerable to the impact resistance of the material, which was easily broken by an external impact. .

Therefore, the present invention has been made in view of the above-mentioned problems in order to be able to simultaneously perform lamination and lacquer on a thin metal plate.

In addition, the present invention is to perform the Najeon and lacquer on a thin metal plate at the same time to diversify the material (base) of Najeon lacquer which is a unique craft of Korea, and at the same time, it is possible to make Najeon and lacquer on a thin plate Regardless, it is also possible to provide a large amount of colorful and elegant ornaments, such as various types of lacquer wares.

In addition, the present invention is able to provide a semi-permanent ornament almost durable by life-proofing and lacquer on all metal sheets excellent in strength, durability and shape preservation of the material, according to the accompanying drawings of the present invention The embodiment is described in more detail as follows.

FIG. 1 is an exemplary view illustrating an embodiment of the present invention, but for the sake of convenience, the present invention is illustrated on the metal thin plate 1 of the dial P of the watch, but the present invention is limited to the metal thin plate 1 of the clock face P. As described above, the present invention can be applied to all metal sheets or metal thin plates without being processed.

Hereinafter, the present invention will be described in detail according to the implementation process state according to the accompanying drawings.

[Step 1]

One side of the thin metal plate 1 to be ground and lacquered is polished with a send paper or the like to smooth the surface and give an uneven wound to form the uneven adhesion surface 2, and the uneven adhesion surface 2. Applying a live lacquer on the adhesive to form a fresh lacquer layer (3), and then repeatedly heated three times for 10-20 minutes at a temperature of about 100-200 ℃ to the raw lacquer layer (3) ) Is firmly formed.

The uneven adhesion surface 2 is formed in this process so that the metal thin plate 1 and the live lacquer layer 3 are firmly and in good condition when the green lacquer layer 3 is formed. By the same uneven adhesive surface (2), the raw lacquer layer (3) is firmly bonded after curing, and also by forming the raw lacquer layer (3) on the metal thin plate (1) in advance by this process, Najeon and lacquer described later The process can be performed perfectly on the same raw lacquer material (see also second (a) and second (b)).

[Step 2]

After the lacquer was repeatedly applied twice on the fresh lacquer layer 3 on the uneven adhesion surface 2 of the metal thin plate 1 formed in the first step, the lacquer layer 4 was formed and ground, and then rice. Mother-of-pearl 5 is adhere | attached in a predetermined pattern or form using the paste mixed with grass and fresh lacquer (refer also to 2nd (c) and 2nd (d)).

[Step 3]

In the second step, a blank (6) mixed with raw lacquer and a sample (6) is filled in the spaces between mother-of-pearl (5) bonded on the lacquer layer (4) of the metal thin plate (1), and then the surface thereof is three times. After grinding finely with whetstone or crystal crushed stone, apply lacquer again three times or more, and arrange the drawings evenly while polishing after each application (see also second (e)).

[Step 4]

In this step, the lacquer portion covering the upper part of the mother-of-pearl 5 is removed with an awl, a knife, or the like, and then the surface is polished with a grindstone or crystal abrasive stone and polished with a fresh lacquer to finish the present invention.

In the present invention, the surface of the metal thin plate 1 is first polished with a send paper or the like to form an uneven adhesive surface 2 to obtain a fresh lacquer, which is repeatedly heated several times at 100-200 ° C. for 10-20 minutes. By completely adhering the raw lacquer layer 3 onto the metal thin plate 1, it is possible to carry out perfect coating on the metal surface such as metal thin plate and lacquer at the same time. It is possible to provide a large amount of folk-specific artefacts that are colorful, excellent in gloss, and express classic beauty on various decorative plates and ornaments made of metal, and its base material is composed of metal plates, so its strength and durability It is excellent and has a feature that can give the same sense to Najeon lacquer in small ornaments and accessories made of metalwork.

Claims (2)

Form an uneven adhesive surface on the surface of the metal plate and apply it to the raw lacquer and repeat the heat treatment three times for 10-20 minutes at the temperature of 100-200 ℃. A method for producing a bare metal decorative plate, characterized by performing a known lacquer and gloss process. A concave-convex adhesive surface was formed on the surface of the metal plate, and a fresh lacquer layer and a lacquer layer were formed on the upper surface of the metal plate. Then, the mother-of-pearl layer was formed, and the lacquer and the stake layer were filled in the spaces between the mother-of-pearl of the mother-of-pearl layer. Next, a method for producing a bare lacquer metal plate by forming a lacquer layer on the upper surface again.
