Abstract

PROBLEM TO BE SOLVED: To improve persistence of a colorant by charging the colorant in a pattern groove formed by breaking a surface of a decorative sheet laminated on a base plate, and forming an overcoating film on the sheet in this state. SOLUTION: A pattern tuned with a pattern design printed on the laminated decorative sheet 10 is formed by a protrusion 13 on an embossing board 12 for erabossing a base plate 11 laminated with the sheet 10. When the plate 11 laminated with the sheet 10 is pressed, the protrusion 13 is intruded in the plate 11 in the board 12, the sheet 10 of the intruded part is broken to form a pattern groove 14. Thereafter, colorant 15 is printed in the groove 14 by coloring wiping. Since the sheet 10 is broken, the colorant 15 is impregnated into the groove 14 to effectively coloring it. Thereafter, it is overcoated to form an overcoating film 16. Thus, the decorative plate formed with a beautiful pattern which is not faded even in the case of using for a long period can be manufactured.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative plate having good adhesion of a coloring agent for forming a pattern (for example, a wood grain pattern) and a method for producing the same.

[0002]

2. Description of the Related Art Veneer veneer plywood has been conventionally known in which a veneer is pasted on a plywood, then subjected to a color wiping treatment and a topcoat is applied. In this veneer, a colorant penetrates into a conduit groove of the veneer. And a very beautiful grain pattern.
However, in recent years, natural precious wood has become precious, and the sheet to be attached to the surface of the decorative board has been changed from veneer to printed decorative paper in order to reduce costs. This decorative paper is manufactured by printing and forming a wood grain pattern, sticking it to a substrate, pressing and molding with a stamping board synchronized with the wood grain pattern to form irregularities, and performing a colored wiping process.

[0003]

However, even if mechanical irregularities are formed on the decorative paper surface, the concave portions are formed to be shallow, and there is a problem that the colorant is not easily mounted on the colored wiping process and the finish is not neatly finished. is there. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a decorative board which has a good finish of a coloring agent in a colored wiping process and is beautifully finished, and a method of manufacturing the same.

[0004]

According to the present invention, there is provided a semiconductor device comprising:
In the decorative plate described above, a coloring agent is filled in a pattern groove formed by breaking the surface of the decorative sheet attached to the substrate, and in this state, a topcoat film is formed on the decorative sheet. . Further, in the method for manufacturing a decorative sheet according to claim 2, the decorative sheet is adhered to the substrate by pressing with a stamping plate having a convex part of a desired pattern from the surface, and the decorative sheet is formed by the convex part. Is broken, and then a coloring wiping process is performed to leave the coloring agent in the broken portion of the decorative sheet, and a top coat is arbitrarily applied.

In the decorative plate according to the first aspect, the decorative sheet in the pattern groove is broken, the portion is filled with the colorant, and further the top coat is applied, so that the fixed state of the colorant is maintained. It becomes better, and as a result, a beautiful pattern can be formed. In the method for manufacturing a decorative plate according to claim 2, the substrate on which the decorative sheet is adhered is pressed with a stamping plate having a convex portion of a desired pattern, and the decorative sheet in that portion is broken, By performing a colored wiping process to leave the coloring agent in the broken portion of the decorative sheet, since the top coat is arbitrarily applied, the fixing state of the coloring agent becomes good,
A beautiful pattern can be formed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention. Here, FIGS. 1A to 1D are process diagrams of a method for manufacturing a decorative board according to one embodiment of the present invention.

As shown in FIG. 1A, a decorative sheet 10 used in a method for manufacturing a decorative board according to one embodiment of the present invention.
Is attached to the substrate 11, plywood, particle board,
Any smooth plate-like body such as an MDF (medium fiber board), a wood board such as a hard board, an inorganic board such as gypsum, and a synthetic resin board can be applied. The decorative sheet 10 to be adhered on the substrate 11 is made of decorative paper such as kraft paper, titanium paper, linter paper, and the like, and is adhered to the substrate 11 with an adhesive such as a common urea resin or vinyl acetate. ing. Further, on the surface of the decorative sheet 10, for example, a grain pattern or the like is printed.

[0008] On the embossing plate 12 for embossing the substrate 11 to which the decorative sheet 10 is attached, a pattern which is synchronized with the pattern printed on the applied decorative sheet 10 is formed by the convex portions 13. As shown in FIG. 1 (B), when the substrate 11 on which the decorative sheet 10 is stuck is pressed (pressed) with the embossing plate 12, the protrusion 13 bites into the substrate 11, and the decorative sheet 10 in that portion is By breaking, the pattern groove 14 is formed.

Thereafter, as shown in FIG. 1 (C), a colored wiping process is performed. In the colored wiping process, after applying a coloring agent (stain) 15 with a roll coater, the sponge roll is rotated in the reverse direction, and the excess The printing is performed in such a manner as to be printed in the pattern groove (recess) 14 while removing the colorant. Since the decorative sheet 10 is broken at the portion of the pattern groove 14, the coloring agent 15 penetrates into this portion (the broken portion), and coloring can be performed reliably.

Thereafter, as shown in FIG. 1D, a top coat is applied. The overcoating is determined by various physical properties such as the use and material of the decorative board, and a transparent or lightly colored urethane resin or polyester resin is used. Although aminoalkyd resins are inexpensive, they are preferably not used except in special cases, since formaldehyde is gradually released. As a result, the colorant in the pattern groove 14 is fixed, and a decorative plate having a beautiful pattern that does not fade even after long-term use can be manufactured. In addition, 16 shows a top coat film.

In the above embodiment, the decorative sheet 1
Although the case of 0 and the pattern of the embossing board 12 synchronized therewith has been described as a wood grain pattern, the present invention is not limited to this, and the present invention can be applied to ordinary graphic patterns or geometric patterns. Further, in the above-described embodiment, decorative paper is used as the decorative sheet, but any other sheet can be applied as long as it is a sheet that is broken by the pattern of the convex portions of the stamping board.

[0012]

According to the decorative board according to the first aspect and the decorative board manufactured by the method for manufacturing the decorative board according to the second aspect, the coloring agent penetrates into the pattern groove and is fixed. Good adhesion, resulting in a beautiful pattern.
