DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of coating a decorative veneer for a building, and more particularly, to a method of applying a tile having a convex portion formed by dividing the surface of a plate-like member into concave grooves for joints. The present invention relates to a method for painting a decorative veneer having a three-dimensional appearance and decorativeness of a natural stone paste.

[0002]

2. Description of the Related Art Conventionally, tiles and natural stones used for finishing the interior and exterior of buildings have been constructed by attaching small pieces of tiles and natural stones one by one with joint cement or the like. Therefore, the tiled finish and the natural stone-finished finish can exhibit a high-grade appearance, but require much labor and skill and are expensive.

[0003] Therefore, the surface of the plate-shaped body is embossed,
After forming convex portions and concave grooves for joints by router cutting method, molding method, etc., apply colored coating to convex portions and concave grooves, and then apply spot coating on the surface of convex portions, By applying fine particles such as fine stones by spraying, a fine skin pattern of tiles and stones is expressed on the surface of the plate-like body, thereby producing tile-like or natural stone-like building decorative boards. That is being done.

[0004]

However, if the above-mentioned convex portions and concave grooves for joints are uniformly coated with a spray coater or a flow coater, the color of the joints and the color of the convex portions become the same. Therefore, it is inferior in decorativeness and cannot express the depth of the concave groove for joints.

Further, when fine stones or the like are adhered to the surface of the painted plate by spraying, or when the paint is applied in a spot pattern by a spray coater, the same is applied to the concave grooves for joints as well as the convex parts. A spot pattern is formed by deposits such as fine stones and the like, and the distinction between the convex portion and the concave groove becomes unclear, so that a deep stereoscopic effect cannot be expressed and the decorativeness is poor. There is.

When fine stones or the like are applied by spraying, there is a risk that the fine stones may fall off the surface of the plate-like body. To avoid this, clear coating with a resin solution is performed on the surface of the attached fine stones. However, there is a problem that the production process is complicated.

[0007] Further, in the case of applying spot coating with a paint, it is practically difficult to control the size of the spots within a preferable range. However, since a portion such as a blurred dirt is formed on the surface of the convex portion, there is also a problem that the decorativeness is reduced.

The present invention solves each of the above problems at once, and enhances the three-dimensional effect by making a visual difference appear between the convex portion on the surface of the plate-like body and the concave groove for joint. It is an object of the present invention to provide a method for coating a decorative board for building, which can perform a decorative pattern with a grain pattern such as a tile or a stone surface only on the surface of a convex portion.

[0009]

In order to achieve the above object, a first aspect of the present invention is to provide a scaly aggregate after applying an opaque paint so that a convex portion and a concave groove have different colors. The transparent or translucent resin liquid mixed with is applied only to the convex portions of the plate-like body by a contact type applicator.

[0010] Specifically, a solution taken by the invention of claim 1 is to apply a method of coating a decorative board for building to a whole surface of a plate-like body having a convex portion and a concave groove for joint formed on the surface. Over the first step of applying a first opaque colored paint having a first color tone, and a second opacity having a second color tone different from the first color tone only on the convex portions of the plate-like body. A second step of applying a colored paint, and applying only a transparent or semi-transparent resin liquid mixed with at least one color of scale-like aggregate by a contact type applicator to only the convex portion of the plate-like body. And a third step of forming a grain pattern only on the convex portion of the plate-like body.

According to a second aspect of the present invention, in the constitution of the first aspect, the third step is a lamination comprising a coating layer formed of a second opaque colored paint and a coating layer formed of a resin liquid. A configuration including a step of applying a resin liquid so that the glossiness of the coating film layer is higher than the glossiness of the coating film layer formed by the first opaque coloring paint is added.

According to a third aspect of the present invention, in the configuration of the first or second aspect, a concave pattern having a depth smaller than the depth of the concave groove is formed on the surface of the convex portion of the plate-like body. It is to be added.

[0013]

According to the first aspect, the first step and the second step
By the step, the coating layer made of the first opaque colored paint having the first color tone is formed in the concave groove of the plate-like body, while the second color tone is formed in the convex portion of the plate-like body. A coating layer made of a second opaque colored paint having the following formula is formed. Next, the third
In the step, the transparent or translucent resin liquid in which the flaky aggregate is mixed only in the convex portion of the plate-like body is applied by a contact type applicator. In the convex portion, the second opaque colored paint is used. A clear grain pattern in which flake-like aggregates are scattered appears on the coating film made of, while the coating film made of the first opaque colored paint remains in the concave groove. For this reason, a clear grain pattern composed of the color of the second opaque colored paint and the color of the scale-like aggregate formed only on the convex portion and the first opaque colored paint formed on the concave groove are obtained. By the synergistic effect with the coating film layer, it is possible to obtain a three-dimensional architectural decorative board rich in natural feeling. Further, in the third step, the transparent or translucent resin liquid mixed with the scale-like aggregate is applied only to the surface of the convex portion by the contact type applicator, so that the resin liquid is not applied to the concave groove. Therefore, the coating layer made of the resin liquid can be efficiently formed only on the surface of the convex portion.

According to the second aspect of the present invention, in the third step, the glossiness of the laminated coating layer composed of the coating layer formed of the second opaque colored paint and the coating layer formed of the resin liquid is adjusted. Since the method includes a step of applying a resin liquid so as to be higher than the glossiness of the coating layer formed by the first opaque coloring paint, the gloss of the convex portion of the plate-like body is higher than the gloss of the concave groove for joints. Therefore, it is possible to obtain a decorative plate having a more three-dimensional feeling and a natural feeling.

According to the third aspect of the present invention, a concave pattern having a depth shallower than the depth of the concave groove for joints is formed on the surface of the convex portion. When you set it, you can express the background of the fired tile,
When the concave pattern is a deep large concave pattern, a stone ground can be expressed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A method for coating a decorative veneer according to an embodiment of the present invention will be described below.

First, a plate 3 having a convex portion 1 and a concave groove 2 for joints formed on the surface is prepared.

The plate-like body 3 having the convex portions 1 and the concave grooves 2 for joints formed on the surface thereof may be, for example, a mixture of a hydraulic binder such as cement and water in a piece of wood, and then a tile pattern formed by an emboss plate. A convex portion 1 and a concave groove 2 are formed and then cured and cured. In this case, the surface of the cured and cured plate 3 may be coated with a base coat such as a sealer coat.

The plate-like body 3 may be made of an inorganic material such as a glass fiber reinforced cement board, an asbestos cement board, a magnesium carbonate board, a pulp cement board, a slag cement board, a calcium silicate board, etc. And those made of these inorganic materials are preferable because they have the texture of tiles and stones and have excellent durability.

The plate-shaped member 3 may be made of a wood material, a synthetic resin material, or the like, in addition to a material made of an inorganic material.

As a method for forming the convex portions 1 and the concave grooves 2 on the surface of the plate-like body 3, a cutting method using a router, a molding method, or the like is employed in addition to the above-described method using the embossed plate. Can be.

Furthermore, a concave pattern 4 having a depth smaller than the depth of the concave groove 2, for example, a fine concave pattern of a grain shape expressing the ground surface of a fired tile, or a stone on the surface of the convex portion 1 It is particularly preferable to use the plate-like body 1 on which a deep and large concave pattern or the like that expresses the skin is formed. As described above, when the concave pattern 4 is formed on the surface of the convex portion 1, the method using the emboss plate is the most productive.

Next, a colored opaque paint is applied to the surface of the plate 3 so that the convex portion 1 and the concave groove 2 have different colors.

The method of applying the colored opaque paint so that the convex portion 1 and the concave groove 2 have different colors is not particularly limited, but, for example, the surface of the plate-like body 3 may be entirely coated. After applying the joint color with a spray coater or a flow coater over the entire surface, only the convex portion 1 is painted in a different color with a roll coater, or the concave groove 2 is covered with a masking material to spray only the convex portion 1. It can be painted in a different color by a coater. Conversely, after the entire surface of the plate-shaped body 3 is painted in the color of the convex portion 1 by a spray coater or the like, only the concave groove 2 may be painted in another color.

The colored opaque paint used here is a so-called enamel paint. For example, an opaque paint obtained by mixing an organic or inorganic colored pigment with a resin component such as a urethane resin, an acrylic resin or an amino alkyd resin is used. It is a paint that is the main component.

The color tone of the colored opaque paint applied to the convex portion 1 and the concave groove 2 is preferably ΔE> 1.0 or more in terms of color difference, as measured according to JIS-Z-8722. More preferably, there is a color difference of> 2.0 or more.

Next, a transparent or translucent resin liquid mixed with at least one color of scaly aggregate is applied to only the convex portion 1 of the plate-like body 3 by a contact type applicator.

The transparent or translucent resin liquid is a resin liquid containing a urethane resin, an alkyd resin, a polyester resin, an acrylic resin, a silicon resin, a fluorine resin, or the like. A colored one can be used.

Further, those to which a pigment such as a coloring pigment is added for imparting appropriate translucency can also be used as the resin liquid of the present invention.

In this case, the glossiness of the multilayer coating film layer of the opaque paint applied to the convex portion 1 and the resin liquid to be applied from now on is determined by the glossiness of the coating film layer of the opaque paint applied to the concave groove 2. It is desirable to use a transparent or translucent resin liquid that is higher than the above.

Here, the term "translucent" refers to a state in which the coating layer of the colored opaque paint is slightly or clearly seen through after application and drying, or in a case where a concave pattern is formed. In this state, the paint is partially thickened, the portion is opaque, and the other portions are slightly or clearly visible.

Specifically, such glossiness is J
When the glossiness of the former is 1.5 times or more the glossiness of the latter according to the glossiness measurement method of IS-Z-8741,
The three-dimensional effect can be further emphasized.

The scaly aggregate is made of plastic,
It is made of ceramic, mica, metal, paper, or the like, and is not a three-dimensional object such as a sphere or a prism, but a flat object having an area larger than the thickness.

The scaly aggregate has a diameter of 0.04 m.
It is preferable to use those having a diameter of about m to 5 mm, because if the diameter is smaller than 0.04 mm, it becomes inconspicuous as a spot pattern, and the diameter becomes larger than 5 mm or becomes something other than a flat shape. In such a case, it is difficult to uniformly apply the resin liquid by the contact type applicator. From such a viewpoint, if a scale-like aggregate having a diameter of 0.2 mm to 2 mm is selected, decorativeness and applicability are further improved.

As such a scaly aggregate, a single color may be used. However, when a plurality of scaly aggregates colored in different colors are mixed and used, a complicated mixed color is obtained. The decorative value can be enhanced because a speckled pattern consisting of

The resin liquid mixed with the scaly aggregate is mixed with the convex portion 1.
As a contact-type applicator that applies only to a varnish, a roll coater is usually used, and a printing machine such as a screen or letterpress can also be used. When the concave pattern 4 is formed on the surface of the convex portion 1, the degree of hardness of the application roll in the roll coater can be selected according to the concave pattern 4.

By applying such a resin liquid only to the convex portions 1, an opaque colored coating layer having a color tone different from the color of the joint groove 2 appears between the scale-like aggregates. An architectural decorative board excellent in texture and decorativeness is obtained. From such a viewpoint, as the density of the flaky aggregate in the resin liquid, the flaky aggregate is 5% to 80% of the surface area of the convex portion 1.
Is preferably set to a degree that conceals.

[0038]

As described above, according to the method for coating a decorative veneer for a building according to the first aspect of the present invention, the coating of the first opaque colored paint having the first color tone in the concave groove of the plate-like body. After forming the film layer and forming a coating layer made of the second opaque colored paint having the second color tone on the convex portion of the plate-like body, the scaly aggregate is formed only on the convex portion of the plate-like body. In order to apply a transparent or translucent resin liquid mixed with a contact type applicator, from the color of the second opaque colored paint and the color of the scaly aggregate that appears only in the convex portions of the plate-like body The synergistic effect of the clear grain pattern and the coating layer made of the first opaque colored paint formed in the concave groove makes it possible to obtain a three-dimensional decorative decorative board rich in natural feeling. In addition, since the transparent or semi-transparent resin liquid mixed with the scale-like aggregate is coated on the convex portion of the plate-like body by the contact type coating machine, the second opaque coloring is performed only on the convex portion of the plate-like body. A clear grain pattern consisting of the color of the paint and the color of the scaly aggregate can be reliably formed.

According to the method for coating decorative architectural boards according to the second aspect of the present invention, a laminated coating layer comprising a coating layer formed of the second opaque colored paint and a coating layer formed of the resin liquid. Since the resin liquid is applied such that the glossiness of the coating is higher than the glossiness of the coating layer formed by the first opaque colored paint, the gloss of the concave groove for joints is lower than the gloss of the convex portion. Therefore, it is possible to obtain an architectural decorative board having a more three-dimensional feeling and a natural feeling.

According to the method for coating a decorative board for construction according to the third aspect of the present invention, since a concave pattern having a depth smaller than the depth of the joint concave groove is formed on the surface of the convex portion, Since the background of the fired tile and the background of the stone can be expressed in the convex portion, the decorativeness of the decorative panel for building can be further improved in combination with the effect of claim 1 or 2.
