DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative panel used for interior and exterior of a house, a building, and the like. , A decorative board having high designability utilizing the pattern, texture and depth of the base material joints).

[0002]

2. Description of the Related Art Conventionally, various decorative boards have been used for interior and exterior of houses, buildings and the like. As the exterior use, a single color coating is applied to an inorganic base material such as ceramic siding or ALC, and decoration by gravure offset or inkjet is known. In addition, ceramic siding that imitates bricks and tiles with a very high-quality feel as an exterior material can perform simpler and less expensive construction than actual brick and tile construction.

However, since these ceramic sidings are mainly manufactured for embossing decoration, the color design is currently lagging behind.
That is, most products are painted in a single color over the entire surface, or are simply painted in two colors using different colors at joints. In particular, most of the joints (recesses) of a decorative board having a brick or tile-like shape are simply coated with a single color, and the finish of the joints becomes uniform, resulting in a texture and texture. There is no sense of depth.

[0004]

Heretofore, not only mere painting but also transfer of a picture has been attempted to improve the design feeling. However, all of them had the same finish and lacked the material feel and depth of the substrate. The present invention has been made to solve such a problem, and an object of the present invention is to provide a decorative board utilizing a pattern, a texture, and a sense of depth of a base joint.

The present invention has been conceived in order to solve the above-mentioned problems, and the invention according to claim 1 has a pattern in a decorative plate base having irregularities, in which a part of a large or small concave part or a whole concave part has a pattern. It is a decorative plate characterized by the above. The invention according to claim 2 is the decorative plate according to claim 1, characterized in that a part of the large pattern or the small concave portion or the entire concave portion has a pattern by an ink jet method.

[0006]

Next, an embodiment of the present invention will be described. FIG. 1 shows an example of a cross section of a decorative board obtained according to the present invention. Sealing treatment (2) is performed on the base material (1) of the decorative board, and the base coat layer (3), the joint pattern layer (4), the convex base coat layer (5), the surface pattern layer (6), and the surface protection A layer (7) is provided.

As the decorative board substrate (1), an inorganic plate-like base material such as MDF, siding material, calcium silicate, asbestos cement board, gypsum slag board, concrete block, ALC, GRC, etc. 2) An embossed base material subjected to a surface polishing treatment or the like can be used.

Further, as shown in the cross-sectional view of FIG. 3, a pattern printing layer (4) made of ink or resin may be provided on the translucent foamed resin layer (3) by a gravure printing method or the like. Good.

[0009] As the base coat layer (3), a layer capable of obtaining close contact between the substrate and the pattern is appropriately selected. For example, phthalic acid resin paint, amino alkyd resin paint, epoxy resin paint, vinyl resin paint, polyurethane resin paint, unsaturated polyester resin paint and the like.

According to the experiments by the present inventors, it was found that the use of a two-part curable acrylic urethane-based coating material allows the properties of both the coating material and the adhesive to be obtained. As a coating method, various coaters such as an air spray, an airless spray, a roll coater, and a flow coater may be used.

As the joint pattern layer (4), a layer which can provide close contact with the base coat layer is appropriately selected, and roll transfer, silk printing, gravure offset printing, spray coating, and inkjet coating are applied to the joint layer. Just paint the picture. According to the experiment of the present inventor, when the inkjet was used, it was possible to achieve a pattern painting with higher definition and excellent design.

[0012] Among the ink jet systems, the continuous type is faster and more favorable. There are aqueous and oil-based inks used for inkjet, but aqueous inks are generally used.

In the ink jet, in order to obtain the optimum flight characteristics, it is necessary to appropriately adjust the viscosity and the surface tension.
A thickener, a surface tension adjuster and the like are added. Therefore, solvents include amides, pyrrolidones, glycols, glycol ethers and the like. Among these, glycols such as dipropylene glycol, diethylene glycol, and polyethylene glycol may be used as a thickener for the ink. With a design of 200 dpi, a material having a sufficient texture was obtained.

The convex base coat layer (5) can be used for imparting concealing properties to a pattern when painting is to be performed by applying a different color to a portion other than the joint portion of the base material or by transferring. According to the experiment of the inventor, it was good to use the same paint as the base coat layer (3). The surface pattern layer (6) can be painted as required by silk printing, gravure offset printing, spray coating, roll transfer method, or the like.

The surface protective layer (7) may be appropriately selected as needed according to the intended use and location, and may be selected from two-part curable urethane resin, fluorine resin, acrylic silicone resin, and inorganic resin. Resin can be used. An ultraviolet absorber and a light stabilizer are added to these as needed. The coating thickness is preferably 10 to 200 μm, glossy, semi-glossy,
It may be glossless.

Next, an embodiment of the present invention will be described.

[0017]

EXAMPLE A two-component urethane resin sealer was applied to a ceramic flat base material having a thickness of 15 mm, and then a base coat was applied to a two-component urethane resin paint (Toyo Ink Manufacturing Co., Ltd.)
(50 g / m ² · dry), and then dried at 120 ° C. for 8 minutes.

Thereafter, a pattern was applied to the joints of the substrate using a continuous ink jet coating machine. In order to increase the painting speed, three inks of four heads and inks of four colors made of high weather resistance were used. For data processing, an image processor with a built-in RISC chip is used for high-speed processing, and digital data used is 200 dpi.

Next, the base coat of the convex portion is coated with a two-part urethane resin based paint except for the joints, and then heated at 120 ° C.
For 8 minutes.

In order to transfer the picture to the projection, the thickness is 120 μm.
m, a polyvinyl butyral resin-based ink is printed on a vinyl chloride sheet, and the pattern surface is bonded to the base coat surface of the base material, and the line pressure is 15 kgf / cm with a rubber roll heated to 180 ° C. with a rubber hardness of 80 °. Speed 7
The pattern layer was transferred at m / min.

The transfer paper is peeled off, and a two-component curable urethane resin transparent protective layer (V-Fron # 700 manufactured by Dainippon Paint Co., Ltd.)
Was painted, dried and cured to complete a decorative board.

[0022]

As described above, according to the present invention, by painting a pattern by the ink jet method on the joint of the base material, the pattern, texture and depth of the joint of the joint of the base material can be utilized as it is on the decorative board. By transferring a pattern that is in harmony with the base material and joint shape by transfer, it is possible to obtain a decorative board with a texture different from the surface of the base material at the joint, instead of the same finish as before. Can be.

Also, by changing the pattern and resolution of the joints arbitrarily, the joints can be intentionally emphasized over the pattern on the surface of the base material, and conversely, the joints can be made to have a higher degree than the pattern on the surface of the base material. By preventing it from being extremely noticeable, it is possible to obtain a high-transfer decorative board made of a design.
