DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a decorative board used for construction, and more particularly to a method of manufacturing a decorative board, wherein a surface of a plate-like body is defined by a concave groove for joints to form a convex portion. The present invention relates to a method for manufacturing a decorative board having a three-dimensional appearance and a decorative property in a tiled tone or a natural stone tone.

[0002]

2. Description of the Related Art Conventionally, tile finishing and natural stone finishing used for finishing the interior and exterior of a building are carried out by sticking small pieces of tile or natural stone 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.

When fine stones or the like are adhered to the surface of the coated plate by spraying or the paint is applied in a spot pattern by a spray coater, the fine stones and the like similar to the convex parts are formed in the concave grooves for joints. Since a spot pattern is formed due to the adhered matter or the paint, the distinction between the convex portion and the concave groove becomes unclear, so that there is a problem that a deep stereoscopic effect cannot be expressed and the decorativeness is poor. .

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. Therefore, large spots adhere to the convex portions, resulting in an unnatural appearance. Also, spots that are so small as to be hard to visually discriminate adhere to the protruding portion, and a portion like a blurred dirt is formed on the surface of the protruding portion.

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 another object of the present invention to provide a method of manufacturing a decorative board 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]

Means for Solving the Problems To achieve the above object, the invention according to claim 1 is to apply an opaque coloring paint to the surface of a plate-like body having a convex portion and a concave groove formed thereon. The scaly aggregate is mixed and the opaque colored paint and the transparent top layer resin paint of a color different from the scaly aggregate are applied only to the convex portions of the plate-like body by a contact type applicator. Things.

[0010] Specifically, a solution provided by the invention of claim 1 is to provide a method for manufacturing a decorative plate, which comprises applying an opaque colored paint to the entire surface of a plate-like body having a convex portion and a concave groove for joints formed on the surface. After coating, only the convex portions of the plate-like body are opaque.
A transparent or translucent top layer tree of a color different from the opaque colored paint and the flaky aggregate is mixed with at least one flaky aggregate having a color tone different from the color paint.
By applying grease paint with a contact type coating machine , it becomes convex.
In addition to the appearance of the flake-like aggregate grain pattern on the
Apply the opaque colored paint coating layer from between the grain patterns to the concave grooves.
The configuration is such that a color tone that can be distinguished from the color tone appears through
Things.

According to a second aspect of the present invention, in the first aspect, the glossiness of the laminated coating layer of the opaque colored paint and the transparent or opaque paint applied to the convex portion is applied to the concave groove. This is to add a configuration in which a transparent or opaque paint is applied so that the glossiness of the applied opaque colored paint is higher than that of the coating layer.

[0012] The invention of claim 3 is claim 1 or claim 2.
In addition to the above configuration, a configuration in which 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 is added.

[0013]

According to the first aspect of the present invention, after the opaque colored paint is applied to the surface of the plate-like body, at least 1
When a flaky aggregate of color is mixed, and a transparent or translucent top layer resin paint of a different color from the opaque colored paint and the flaky aggregate is applied by a contact-type coating machine, a convex portion is formed. A clear grain pattern due to scaly aggregates appears only on the surface. Such scaly aggregates are different in color from the opaque colored paint and the transparent or translucent paint, and are mixed with the top paint and applied by a contact type applicator, so that the scaly aggregates have a substantially area. It clearly appears on the top layer of the decorative board surface with the large part as the surface. Furthermore, a decorative board with a three-dimensional appearance rich in natural feeling can be obtained in combination with the difference in color tone and texture between the convex portion and the concave groove. In this case, when a transparent or translucent resin paint mixed with scaly aggregates is applied to the surface of the convex portion by a contact type applicator, the resin paint is not applied to the concave groove, so the surface of the convex portion is Only can be painted efficiently.

According to the second aspect of the present invention, the glossiness of the laminated coating layer of the opaque colored paint applied to the convex portion and the transparent or translucent paint is reduced. for applying a transparent or opaque coating to be higher than the gloss, more towards the convex portion of the concave groove for joint because the light <br/> Sawa becomes low, more three-dimensional appearance and naturalness A decorative board can be obtained.

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, and the concave pattern is formed into a fine concave pattern of a grain shape. If it is set to, the background like a fired tile can be expressed, and if the concave pattern is made into a deep large concave pattern, the background of a split stone can be expressed.

[0016]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a method for manufacturing a decorative board according to one embodiment of the present invention will be described.

First, a plate-like body having a convex portion and a concave groove for joints formed on the surface is prepared.

As a plate-like body having a convex portion and a joint concave groove formed on a surface thereof, for example, a wood piece is mixed with a hydraulic binder such as cement and water, and then a tile pattern or the like is formed by an emboss plate. A shape and a concave groove are formed, and then cured and cured. In this case, a base coat such as a sealer coat may be applied to the surface of the cured and cured plate-like body.

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

The plate-shaped body may be made of a woody material or a synthetic resin material in addition to an inorganic material.

As a method of forming the convex portions and the concave grooves on the surface of the plate-like body, a cutting method using a router, a molding method, or the like can be adopted in addition to the above-described method using the emboss plate.

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

Next, a colored opaque paint is applied to the entire surface of the plate-like body by a spray coater, a flow coater or the like.

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

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

The transparent or translucent paint includes urethane resin, alkyd resin, polyester resin,
A paint containing an acrylic resin, a silicone resin, a fluorine resin, or the like, which is colored by a color pigment or the like so as to have a color different from that of the opaque colored paint so as not to lose transparency or translucency can be used. .

In this case, the glossiness of the laminated coating layer of the opaque colored paint applied to the convex portion and the transparent or translucent paint to be coated from now on is determined by the opaque colored paint applied to the concave groove. It is desirable to use a transparent or translucent paint that has a higher gloss than the layer.

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.

Here, the term "transparent or translucent" refers to a state in which the coating layer of the colored opaque coating is clearly or slightly seen through after application and drying, or a concave portion having a concave shape as in the case where a concave pattern is formed. This means that the paint is partially thickened and this part is opaque, and the other part is clear or slightly transparent.

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 square, but a flat object having an area larger than the thickness.

The scaly aggregate has a diameter of 0.04 m.
Those having a size of about m to 5 mm can be used. The reason is that when the diameter is smaller than 0.04 mm, it becomes inconspicuous as a spot pattern, and when the diameter is larger than 5 mm or becomes something other than a flat shape, the resin liquid is uniformly dispersed by a contact type coating machine. This is because application becomes difficult. 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 the scaly aggregate, a color different from the opaque colored paint and the transparent or translucent paint may be used, and a single color may be used. When a plurality of scaly aggregates colored in a mixture are used, a spot pattern composed of a complex mixed color can be expressed, so that the decorative value can be enhanced.

A roll coater is usually used as a contact type applicator for applying the paint mixed with the scale-like aggregate only to the convex portions, and a printing machine such as a screen or a relief plate may be used. it can. When a concave pattern is formed on the surface of the convex portion, the degree of hardness of the application roll in the roll coater can be selected according to the concave pattern.

[0034] By applying such a transparent or translucent paint only the convex portion, concave from between between scaly aggregate
A decorative plate excellent in three-dimensional appearance and decorativeness in which a non-transparent colored coating film layer having a color tone that can be distinguished from the color tone of the opaque colored coating film layer of the groove is obtained.

[0035]

As described above, according to the method for manufacturing a decorative plate according to the first aspect of the present invention, after applying an opaque colored paint to the surface of the plate-like body, only the convex portion has at least one color. A flake-like aggregate is mixed therein, and the opaque colored paint and a transparent or translucent color of a different color from the flake-like aggregate .
Since the resin coating for the top layer is applied as a top layer by a contact type applicator, a clear spot pattern due to scaly aggregates appears only on the convex portions, and a clear spot pattern appears between the clear spot patterns and the spot patterns. The joint color that comes out and the coating layer of a different color are combined
Thus, it is possible to form a decorative plate having a three-dimensional effect rich in natural feeling.

Further, since the flake-like aggregate is mixed into the transparent or translucent paint, it is easy to apply the paint by the contact type applicator even though the paint contains the aggregate.

According to the method of manufacturing a decorative board according to the second aspect of the present invention, the glossiness of the laminated coating layer of the opaque colored paint and the transparent or translucent paint applied to the convex portions is applied to the concave grooves. Since a transparent or translucent paint that is higher than the glossiness of the coating layer of the opaque colored paint is applied, the concave grooves for joints have a lower gloss than the convex parts, so that a more three-dimensional appearance and natural A decorative plate with a feeling can be obtained.

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