Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative plate for use as a surface material such as doors for interiors of houses and shops, storage furniture and the like.

[0002]

2. Description of the Related Art As a conventional decorative board, after laminating decorative sheets printed with the grain direction of wood grain in only one direction of vertical direction or right angle direction, grooves are provided only in one direction of the fiber direction. The above-mentioned products or a decorative plate in which only decorative sheets printed in two fiber directions are laminated are known and have poor designability.

[0003]

However, in the prior art as described above, in the former case, the groove is provided only in one direction, and the plates are stuck in only one direction. It is used for the purpose of putting out. On the other hand, the latter has a smooth surface and does not have a three-dimensional effect, and is poor in design.

The present invention has been made in view of the above problems, and has a three-dimensional structure in which the wood pattern of the decorative plate has two or more fiber directions, and the surface is grooved and the groove is colored with a paint. The purpose is to provide an interior material which is excellent in design and design.

[0005]

In order to achieve the above object, the three-dimensional decorative board of the present invention has a decorative sheet laminated on the surface layer of a wood-based substrate, and the decorative sheet surface is then formed into a desired shape using a router. It is characterized in that a groove is bored in the groove, and paint is applied to the groove portion.

Further, the decorative sheet comprises a transparent plastic sheet, a back surface of which is provided with a wood grain pattern printing layer having at least two fiber direction regions and a concealing solid layer, and a gloss adjusting top which covers the entire surface of the sheet. A coating layer and a conduit printing layer of a matte ink in synchronism with the wood grain pattern printing layer are provided, and after the decorative sheet is laminated on a wood board, at least a joint portion in the fiber direction of the wood grain pattern printing pattern. It is characterized in that the groove part which is made to be bored by the router is processed and the paint is applied.

[0007]

In the three-dimensional decorative board having the above structure, there are two or more wood grain patterns in the fiber direction, and the wood grain pattern and the conduit pattern are in synchronization with each other. Since the groove is coated and colored with paint, it is three-dimensional and has excellent design.

EXAMPLES Examples will be described below with reference to the drawings.

FIG. 1 is obtained by the manufacturing method of the present invention,
A plan view of the three-dimensional decorative board, FIG. 2 is a sectional view of the three-dimensional decorative board taken along the line I-I, FIG. 3 is a sectional view of the decorative sheet, and FIG. 4 is a plan view of the decorative sheet. Board 1
Is composed of a decorative sheet 2, a substrate 8, grooves 9, and a colored paint 10.

The decorative sheet 2 is provided with a gloss-adjusting top coat 4 and a conduit print 3 on the surface of a base film 5, and has a wood pattern print 6 and a concealing solid layer 7 on the back surface. The wood pattern print 6 and the conduit print 3 The fiber direction of the frame 61 is provided in the vertical direction of the three-dimensional decorative board 1 and the central part 62 is provided at a right angle direction, and the fiber directions intersect at the joint 63, and the wood pattern printing 6 and the conduit printing 3 are synchronized. There is.

As the base film 5, a transparent film of polyvinyl chloride resin, polyester resin, acrylic resin or the like can be used. Especially, polyvinyl chloride is suitable, and the thickness of the film is good for strength and printing work. Considering the ease of post-processing, the range of 0.08 to 0.3 mm is preferable.

The grain pattern printing 6 and the concealing solid layer 7 may be provided on the back surface of the base film 5 by a conventional printing method using an existing printing ink, and the ink for printing the gloss adjusting top coat 4 and the conduit printing 3 may be used. However, in the case of the conduit printing 3, for example, black or dark brown dark ink is used as the color tone, and it is preferable that the gloss has a higher matte effect than the gloss adjusting top coat 4.

The gloss adjusting top coat 4 is made of urethane resin, and the gloss is adjusted by dispersing an appropriate amount of the matting agent. The matting agents that can be used are silica, calcium carbonate,
It is an inorganic filler such as silica sand and shirasu balloon.

The substrate 8 used in the present invention is made of wood such as plywood, medium density fiberboard, particle board, gypsum board,
It is made of inorganic plates such as asbestos perlite board and calcium silicate board, and the decorative board obtained by using these can be immediately used as a surface structural material for interior doors and storage furniture.

The width and depth of the groove 9 to be bored in the present invention are 2 to 6 mm for both the vertical groove and the horizontal groove and 1.5 to 3 for the depth.
It is preferable that the thickness is mm. When drilling to such a size, the portion surrounded by the vertical and horizontal grooves is three-dimensionally lifted, and it looks as if natural wood boards were pasted together.

Further, since the conical blade of the NC router is used for drilling, a clean cross groove can be formed without leaving a cut portion at the crossing portion of the vertical groove and the horizontal groove. Further, since the groove is formed at the crossing portion in the direction of the wood grain fiber, even if the pattern of the wood pattern and the conduit pattern are slightly detuned at the time of printing, the groove is deleted and becomes inconspicuous within the range of the groove width.

As the colored paint 10 to be applied to the groove, a natural resin or a modified resin thereof, a cellulose derivative, a polyvinyl chloride resin, an acrylic resin or the like is used as a vehicle, and a coloring pigment, a matting pigment or a plasticizer is used. Etc. are added, and the color tone is made slightly darker depending on the grain pattern, or vice versa. It is desirable to adjust the gloss to be lower than the grain surface. As a coating method, a wiping treatment after coating with a roll coater or a knife coater, or a masking spray is used.

Example 1 On a back surface of a transparent polyvinyl chloride film (Riken vinyl, R type) having a thickness of 0.12 mm, a wood pattern pattern of an H type door was printed with a vinyl chloride resin ink (Showa Ink, Chemical X). ,
On the upper surface, a concealing solid layer is also applied with a vinyl chloride resin ink (Showa Ink, Chemical XN07), and then a urethane gloss adjusting ink (Showa Ink, OP-80) is used on the surface of the transparent polyvinyl chloride film. On the gloss adjusting layer, an acrylic ink (Showa Ink, G & M) was used for inline printing with a gravure rotary printing machine in line with the wood grain pattern pattern to obtain a decorative sheet.

1. Adhesive CVC36 (made by Konishi) with a thickness of 2.
The entire surface of a 7 mm-sealed plywood was coated with a roll coater at 90 g / m ² and the above decorative sheet was laminated thereon so that the concealing solid layer and the adhesive layer were in contact with each other.

Then, using an NC router, two grooves having a width of 5 mm and a depth of 1.5 mm are provided in parallel with the joint between the frame and the cross grain part, and 7 in the cross grain part in the direction perpendicular to the groove. I punched a book. A three-dimensional H-shaped door surface material was obtained by applying a matte paint, which was slightly darker than the wood grain pattern, to the groove.
