Description: TECHNICAL FIELD The present invention relates to a decorative plate used for construction and furniture manufacturing, and more particularly to a decorative plate having a wood surface pattern such as a conduit hole as a recess and a method for manufacturing the same.

(Prior Art) Conventionally, as a decorative plate having a wood hole pattern such as a conduit hole as a concave portion, a sliced veneer of natural wood is attached to the surface of a substrate such as plywood and formed by the conduit hole of the veneer. A concaved part filled with a colored paint, a concave part with a wood-skin pattern embossed on the surface of the substrate and filled with a colored paint, and a decorative paper with a wood pattern printed on the surface of the substrate. There is also one in which an adhesive is applied and embossing is performed in synchronism with the printed wood grain pattern conduit hole, and the recess is filled with a colored paint.

However, in each case, there is a drawback that only the wood surface pattern such as the conduit hole is emphasized and the natural texture of the whole wood pattern is lacking.

(Problems to be Solved by the Invention) An object of the present invention is to eliminate the defect in the conventional product that lacks the natural taste of the whole wood grain pattern.

(Means for Solving the Problem) The present invention provides a substrate surface by providing a base color paint layer on the surface of a substrate having a wood-skin pattern such as a conduit hole as a recess so as to penetrate into the recess of the wood-skin pattern. The present invention provides a decorative board that can unify the color tone of the above and can enhance the wood surface pattern due to the conduit holes and the like by the colored paint that has penetrated into the recesses such as the conduit holes.

Further, the present invention provides a decorative board which can suppress the peeling of the undercoating color paint layer by providing a transparent paint layer on the upper surface of the undercoating color paint layer, and can give a three-dimensional effect by embossing a wood texture pattern such as a conduit hole. Is provided.

Further, according to the present invention, by providing a wood grain pattern printing layer on the upper surface of the transparent paint layer, it is possible to have a wood grain pattern below and a wood grain pattern above through the transparent paint layer. The present invention provides a decorative board which has an extremely three-dimensional structure and gives a natural grain pattern.

That is, the present invention, on the surface of a substrate having a wood-skin pattern such as a conduit hole as a recess, to provide a base coloring paint layer by permeating into the recess of the wood-skin pattern, a transparent coating layer on the surface of the base coloring paint layer. The gist of the present invention is the structure of a decorative plate characterized in that a wood grain pattern printing layer is provided therethrough, and the present invention clearly has a conduit hole or the like that forms a wood pattern on the surface of the substrate as a recess. A hardwood layer, or
A wood pattern such as a conduit hole is formed as a recess on the surface of the substrate by embossing, and a colored base paint is applied to the surface of the substrate so as to penetrate into the recess where the wood pattern is formed. A gist of the present invention is to provide a method for producing a decorative board, which comprises applying a sanding sealer and drying it, and then smoothing the surface and printing a wood grain pattern.

(Function) The substrate used in the present invention is mainly a wood board, but is not particularly limited thereto. As the wood board, when using hardwood such as Lauan, where conduit holes, medullary lines, etc. are clearly present as recesses, and when softwood materials such as Agathis (South Sea sugi) with relatively few conduit holes, medullary lines are used. May be used.

First, the surface of the substrate is sanded to remove fluff and dirt, and the base is adjusted. For sanding, finest particles are used, for example, sandpaper of No. 150-300.

Among the substrates whose bases have been adjusted, those that are made of hardwood, etc., in which wood grain patterns such as conduit holes are clearly present as recesses are used as they are. On the other hand, if the surface texture of the conduit holes is relatively few or not visible, the surface texture of the conduit holes is embossed with embossing sugar or the like.

Then, for the purpose of matching the color tone of the substrate surface, and for the purpose of emphasizing the concave portions that form the wood surface pattern such as conduit holes or the embossed wood surface pattern, the color coat of the ground color of the wood pattern to be applied later is applied by the roll coater or reverse coater. Apply it to the substrate surface using a coater or the like. As the base color paint to be used, a color paint generally used for wood, plywood, etc. can be appropriately selected and used, but it is preferable to select a sealer to be applied thereafter and a good adhesion thereof. In addition, this base color paint is used in order to facilitate the permeation of the recesses formed as a wood texture pattern.
On the other hand, it is preferable to mix the solvent at a ratio of about 1 to 7 and dilute it before use. In addition, the application of this base coloring paint,
It can be repeated several times if necessary.

After the base color paint is dried, a transparent sanding sealer is applied to the surface of the base color paint by a roll coater or the like as a presser for the base color paint. The amount of transparent paint applied is
About 10 to 12g per square meter is enough.

Next, of sanding sealers consisting of polyester resin type, urethane resin type, amino alkyd resin type, etc.,
A transparent sanding sealer that adheres to the sanding sealer that holds down the colorant is used to apply 70 to 100 g per square meter of rice with a roll coater, reverse coater, flow coater, etc. to form a transparent coating layer.

After this is dried, it is sanded with a No. 400 sandpaper, or sanded to make the surface smooth.

Furthermore, using a gravure offset printing machine, a 1- to multi-colored wood grain pattern is printed on the transparent paint layer with a smooth surface by a conventional method, and finally a transparent or semi-transparent paint is applied (top coat). By doing so, the decorative board of the present invention can be obtained.

(Example 1) The surface of a lauan plywood having a thickness of 2.5 m / m is sanded with sandpaper No. 240 to adjust the groundwork.

Next, a woodworking pigment colorant (Seekstin PG. Woshin Kagaku) white 78% by weight, brown 8% by weight, yellow 13% by weight, and red 1% by weight are toned.
The colorant 1 toned is diluted with a ratio of thinner 5 to prepare a base color of wood.

While using this roll coater with a sponge roll set, press-fit and infiltrate this adjusted undercoat coloring paint into recesses such as conduit holes on the surface of the under-prepared lauan plywood.
Apply over the entire surface with a coating amount of g / m ² . This is repeated twice to dry.

Clear urethane sanding sealer (85% by weight sealer, thinner) to hold down painted surface paint
15% by weight) is applied with a roll coater at 10 g / m ² and dried.

Transparent urethane sanding sealer (sealer 85
90% / m ² with a reverse coater and dried to provide a thick transparent paint layer on the entire surface.

The surface of the transparent paint layer is water-polished (polished) with No. 400 sandpaper using a wet sander (wet final sander), and the groundwork for the next grain pattern printing is adjusted.

Further, a two-color printing of oak grain pattern was carried out with a commonly used oil-based ink by a gravure offset printing machine, and finally urethane clear was overcoated with a roll coater at 20 g / m ² to obtain a decorative board of the present invention. .

(Example 2) The surface of an agatis plywood having a thickness of 3.6 m / m is sanded with No. 240 sandpaper to adjust the groundwork.

Apply a transparent amino alkyd sanding sealer to the surface of the plywood surface adjusted with a roll coater.
Apply g / m ² and dry.

A conduit pattern of walnut material is pressed by an embossing roll on the surface of the plywood coated with the sanding sealer.

Next, 71% by weight of woodworking pigment colorant, black,
Prepare a walnut base color by diluting with a thinner at a ratio of 1: 7, adjusting tones of 18% by weight and 11% by weight of brown.

Using the roll coater in which a sponge roll is set, the adjusted base coloring paint is pressed into the recess formed by embossing and allowed to permeate while being coated on the entire surface at a coating amount of 40 g / m ² and dried.

A transparent amino alkyd sanding sealer is applied by a flow coater at 100 g / m ^{2 and} dried to form a transparent paint layer.

Polish the surface of the transparent paint layer with a wide belt sander using No. 360 sandpaper to adjust the groundwork for the wood grain pattern printing.

Furthermore, a walnut wood grain pattern is printed in two colors with a commonly used oil-based ink by a gravure offset printing machine, and finally, an amino alkyd clear is overcoated with a roll coater at 20 g / m ² to finish, so that the decorative board of the present invention is finished. Got

(Effect) According to the present invention, since the base color paint layer is provided on the surface of the substrate having the wood texture pattern such as a conduit hole as the recess so as to penetrate into the recess of the wood texture pattern, the color tone of the substrate surface is unified. At the same time, the colored paint that has penetrated into the recesses such as the conduit holes has the practical advantage of being able to emphasize the wood surface pattern due to the conduit holes.

Further, according to the present invention, since the transparent paint layer is provided on the upper surface of the undercoating paint layer, it is possible to suppress the peeling of the undercoating paint layer and to make the surface texture of the conduit hole and the like stand out to give a three-dimensional effect. Have a real benefit.

Further, according to the present invention, since the wood grain pattern printing layer is provided on the upper surface of the transparent paint layer, it is possible to have a wood grain pattern below and a wood grain pattern above through the transparent paint layer. The entire pattern becomes extremely three-dimensional and has the practical benefit of obtaining a natural grain pattern.
