Description

TECHNICAL FIELD [0001] The present invention relates to a decorative panel having a pattern formed thereon,

The present invention relates to a decorative panel in which a pattern is formed and a method of manufacturing the decorative panel. More particularly, the present invention relates to a decorative panel having a pattern formed thereon, To a decorative panel having a pattern that can be exposed to the outside through a through groove, and a method of manufacturing the decorative panel.

It is necessary to print various image patterns and form a surface pattern in order to give a luxurious feel to the flat surface of the metal material constituting the interior and exterior materials of the elevator, automobile or various household appliances and various doors.

Conventionally, in the surface processing of a metal material such as stainless steel, aluminum or titanium, various image patterns are printed by chemical etching or silk screen technique. Conventional techniques such as chemical etching or silk screen have been disadvantageous in that it is not only impossible to precisely implement an image pattern of several tens of millimeters (mm) or less, but also causes environmental pollution.

Recently, a metal surface treatment technique using laser has been developed.

Such a technique uses a laser beam as a light source to melt or remove part of a metal surface, thereby realizing a desired image pattern on the surface of a metal material.

On the other hand, there is a decorative panel in which a plurality of films or resin layers are laminated on a metal plate or the like.

In this case, in order to form a pattern on the decorative panel, a predetermined pattern or the like is formed by etching a film or a resin layer with a laser, and a protective film or a protective resin layer is laminated thereon to protect the pattern.

However, in this method, since a film or the like must be laminated and a protective film or the like must be laminated thereon after etching it with a laser, the operation time and work process are long and uneconomical.

2 (b), the pattern layer 30 may be formed with a scratch on the surface of the PET film 31 to form the pattern.

The method of manufacturing the decorative panel of the present invention as described above comprises a panel preparing step and an etching step.

3 (a), the panel preparation step is performed in a state where the base layer 10, the print layer 20, the pattern layer 30, and the protective layer 40 are stacked from the bottom to the top Panel.

At this time, the print layer 20 and the pattern layer 30 are formed of a film, and the base layer 10 may have a plurality of layers as described above.

More specifically, in the panel preparation step, a laminated film layer composed of the PVC film 12, the adhesive layer 13, the print layer 20, the pattern layer 30 and the protective layer 40 is formed on the substrate Layer 11 so as to prepare the panel.

That is, after the worker purchases the previously produced laminate film layer, the laminate film layer is bonded to the substrate layer 11 made of a metal plate or the like.

FIG. 4 shows a photograph of a panel having completed the above panel preparation step.

The color of the surface of the panel is the same as that of the print layer 20 because the protective layer 40 and the pattern layer 30 are transparent.

As shown in FIG. 3 (b), the etching step irradiates a laser beam onto the pattern layer 30 and the print layer 20 constituting the panel, (50) is formed in the layer (30) and the print layer (20).

The through grooves 50 formed in the etching step form characters, figures, figures or numbers.

FIG. 5 shows a photograph of the decorative panel after the etching step as above.

5, the pattern and the letter shape are formed by etching the pattern layer 30 and the print layer 20 with a laser beam as described above, so that the black color shown in the drawing and the alphabet And the black color of the PVC film 12 appears through the through groove 50 to the outside.

Since the hue of the PVC film 12 is exposed to the outside as described above, the hue of the PVC film 12 can be changed into various hues to easily realize various colors in the shape of the through grooves 50.

The through grooves 50 may be formed by irradiating the adhesive layer 13 and the PVC film 12 with not only the pattern layer 30 and the print layer 20 but also the pattern layer 30, Layer 20, the adhesive layer 13 and the PVC film 12 so that the color of the base layer 11 is exposed to the outside.

The laser beam is focused on the pattern layer 30 and the print layer 20 so that the laser beam passes through the protective layer 40 without etching the pattern layer 30, The printed layer 20 is etched to form the through-hole 50. [

More specifically, in order to expose the color of the PVC film 12 to the outside in the base layer 10 composed of the base layer 11, the PVC film 12 and the adhesive layer 13, The pattern layer 30 and the print layer 20 are etched to form the through-hole 50.

The pattern layer 30, the print layer 20, the adhesive layer 13 and the PVC film 12 are etched using a laser beam to expose the color of the base layer 11 to the outside, So that the groove 50 is formed.

As described above, according to the present invention, a laminated film layer is formed by laminating a plurality of layers, and the laminated film layer is bonded to the base layer 11 to prepare the panel. The pattern layer 30 and / The through hole 50 is formed by etching the print layer 20 or the like so that the manufacturing process and the manufacturing time are shortened and the through groove 50 for expressing the design or the character of the desired shape by the customer is formed at a desired position It can be easily formed as shown in FIG. 5 by irradiating a laser beam.

That is, after purchasing a laminated film layer in which a plurality of layers are laminated, a penetrating groove 50 is formed by irradiating the laser beam to the laminated film layer, and characters or the like are formed through the penetration grooves 50. Therefore, The manufacturing time and the manufacturing process can be shortened, and it is more economical than the case where the through grooves 50 are formed.

6 is a comparative diagram comparing the manufacturing process by the decorative panel according to the first embodiment of the present invention and the manufacturing process of the conventional decorative panel.

6 (a), the film layer 61 and the base layer 10 are prepared and adhered, and then the top of the film layer 61 is etched to form a through groove 50, A protective film (62) is laminated on the upper part of the through groove (50).

In contrast, in the present invention, as shown in FIG. 6 (b), the clad film layer 63 and the base layer 10 are prepared and bonded, and then the inside of the clad film layer 63 is etched to form the through grooves 50 ), It is possible to shorten the manufacturing process and the manufacturing time as compared with the conventional technology.

In the present invention, since the laminated film layer 63 is adhered to the base material layer 11 and then the laser beam is irradiated to form the penetrating grooves 50, characters corresponding to the shape and position desired by the customer are inserted into the through- (50).

The decorative panel of the present invention is exposed to the outside of the base layer 11 or the PVC film 12 through the through hole 50 as well as the printing layer 20 and the pattern layer 30, As shown in FIG. 5, it is possible to realize a decorative panel having various colors and patterns 33 by expressing different colors of letters and the like expressed through the through-holes 50.

The decorative panel of the present invention can be applied to decorative panels for building materials (fire doors, elevators), decorative panels for interior (furniture), decorative panels for electronic products, and the like.
