DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. The present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

A method of manufacturing a decor plate product that can be easily implemented in multiple colors according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2A to 2F.

An anodizing process is performed on the aluminum plate 1 to oxidize the entire upper surface of the aluminum plate 1 so that the oxidation film 2 is formed as shown in FIG. .

At this time, the oxide film 2 formed over the entire upper surface of the aluminum plate 1 has a porous structure due to surface oxidation, and forms a surface roughness on the upper surface of the aluminum plate 1, Is a pretreatment process for increasing the brightness and color saturation as well as durability of the color coating exposed in the primary color anodizing or the n-th color anodizing to be performed in the light emitting device.

Such an oxide film 2 is also a basic step for displaying the base color of the product and may be anodizing treatment techniques such as an oxalic acid method, a sulfuric acid method or a coloring method, or an anodizing treatment technique such as black, white, , Red, and so on.

Here, when the step of impregnating an aluminum plate with an electrolytic solution containing an electrolytic solution or an electrolytic solution containing a dye and applying a positive electrode (+) to the upper surface of the aluminum plate and conducting electricity is performed, the surface of the aluminum plate is oxidized A coating of aluminum oxide is formed, and when a dye is mixed, various color coatings can be formed.

2b, laser marking is locally performed on the aluminum plate 1 having the oxide film 2 so that a portion of the aluminum plate 1 having the oxide film 2 has a first laser marking portion 3 (S2).

At this time, the first laser marking portion 3 has a structure in which the thickness of the first laser marking portion 3 is reduced compared to the portion where no laser marking is performed, and is a portion where the oxide film 2 is removed and the laser marked surface of the aluminum plate 1 is exposed.

Here, the first laser marking unit 3 may be a circle, an ellipse, a rectangle, or the like as in the example shown in Fig. 3, may be a brand logo of a corporation, and may be a symbol, a number, or a letter. Sometimes it can be a pattern such as spin (rotating pattern), hair line (wave pattern) or hologram (interference pattern).

Further, it may be a form in which two or more kinds of these various images or patterns are mixed.

Further, the first laser marking unit 3 may be formed by continuously arranging shapes such as a circle, an ellipse or a quadrangle in a continuous manner as shown in the example of FIG. 4, The surface roughness of the surface of the superimposed portion can be increased. Therefore, it is possible to increase the brightness and saturation of the superimposed portion in the color film displayed in the subsequent primary color anodizing, The display can be implemented.

In addition, the first laser marking unit 3 can display the thickness of the neighboring shapes (processing depth) differently, while continuously arranging the shapes of circles, ellipses, or squares or the like, as in the example shown in Fig. 5 This is because it is possible to cause a difference in brightness and chroma on the overlapped portion and the non-overlapped portion through the difference in the thickness (processing depth) with respect to the overlapping portion in the color coating displayed at the first color anodizing to be performed later Therefore, it is possible to implement color expression with a different feeling for each array.

The aluminum plate 1 including the first laser marking portion 3 is subjected to primary color anodization to form a first color coating 4 in the first laser marking portion 3, (S3).

At this time, according to the marking form of the first laser marking unit 3, the first color coat 4 has one identical color, and colors having a difference in lightness and chroma are displayed. Therefore, , And the first color coating (4) can be expressed in various colors such as white, silver, gold, and red depending on the color of the dye used.

In the first color anodizing, the aluminum plate 1 including the first laser marking portion 3 is impregnated into an electrolytic bath containing an electrolyte in which the dye is mixed, and the positive electrode (+) is applied to the first laser marking portion 3, And the first color coating 4 is formed in the first laser marking portion 3. In this case,

On the other hand, the second laser marking is locally performed on the product obtained through the third step (S3) in order to expose completely different colors to the product of the decor plate, and as shown in FIG. 2d, 5) are formed (S4).

At this time, the second laser marking unit 5 can be formed separately from the first laser marking unit 3, and the first laser marking unit 5 having the first color coating 4, as in the example shown in FIG. 6, Or may be formed in the first laser marking portion 3 having the first color coat 4, as shown in FIG.

In addition, a part of the first color coating 4 may be removed by the second laser marking unit 5. [

The second laser marking unit 5 may have a thickness (processing depth) different from that of the first laser marking unit 3 having the first color coating 4, and the first laser marking unit 3 ) Can be formed by selecting any one of an image or a pattern corresponding to the pattern.

Next, the aluminum plate 1 including the second laser marking portion 5 is subjected to secondary color anodization to form a second color coating (not shown) in the second laser marking portion 5 6) are formed (S5).

In this case, the second color coating 6 can be expressed in different colors from the first color coating 4 as shown in the example shown in FIG. 7, and in particular, when they are formed to overlap with each other, You can also implement a completely new color.

In the second color anodizing, the aluminum plate 1 including the second laser marking portion 5 is impregnated into the electrolytic bath containing the electrolyte in which the dye is mixed, and the anode (+) is impregnated into the second laser marking portion 5, And the second color coating 6 is formed in the second laser marking portion 5. In this case,

On the other hand, in the case of primary or secondary color anodizing, it may be possible to perform a work of applying a cushioning agent or attaching a masking tape to a portion of the aluminum plate 1 which is not desired to be corroded, By varying the donor voltage, different colors can be displayed.

After the first color coating 4 or the second color coating 6 is formed by primary or secondary color anodizing, a sealing layer (not shown) is formed with a transparent sealing liquid as shown in FIG. 2F 7) are formed and then subjected to a sealing process to protect the color coatings (4) and (6), as well as to increase the corrosion resistance (S6).

At this time, the sealing process may be performed over the entire surface of the aluminum plate 1, or only locally where the first color coating 4 and the second color coating 6 are formed.

Such a sealing treatment may be carried out after the primary color anodizing is carried out when the secondary color anodizing is not carried out.

Finally, a desired shape is cut or processed by laser, CNC or press (S7).

In the embodiment of the present invention, the laser marking and theanodizing are performed once or twice, but the laser marking and theanodizing may be repeated three times or more.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Which will fall within the technical scope of the present invention.
