DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a patterned coating film, a decorative plate,
And their manufacturing methods. More specifically, the present invention relates to a patterned coating film having a more realistic feeling such as stone texture, a decorative veneer, and a patterned coating such that such a coating film and a veneer can be easily mass-produced at low cost. The present invention relates to a method for producing a membrane and a decorative board.

BACKGROUND OF THE INVENTION Conventionally, as a method for producing a decorative board having a pattern having, for example, a tile-like uneven portion and a concave portion and a convex portion having different colors, a dot-like (sputter) spray coating method and the like are known. . The sputter coating method is a method of spraying a paint on an object to be coated in a dot pattern to perform coating with a tile pattern, and the same paint adheres in a dotted pattern on the entire uneven portion of the object to be coated. It is impossible to apply the paint only to the concave portion and not to apply it to the concave portion.

For this reason, conventionally, in order to make it look as if sprayed only on the projections of the base material, first, the entire surface of the projections and depressions of the base material are painted in a specific color, and then only the surface of the projections is subjected to a roll coater. A color is applied, and then a paint of the same color as that of the concave portion is sprayed on the entire concave / convex portion in a dot shape to form a pattern of one color. However, in this method, a pattern of two or more colors cannot be obtained.
In the case where two or more color paints are sprayed, a dot-like pattern is formed in the concave portion, which is not preferable in appearance.

[0004] As such a paint for pattern coating, there is a water-based pattern forming paint in which colorant particles or colored silica sand which is insoluble in a solvent are dispersed.
(About 10 μm), the pattern is small and poor in design.

[0005] For this reason, there has been a demand for the development of a coating method which is adaptable to line production in factories and the like, and which can produce a decorative board having a pattern with a design tone at a low cost by a simpler process. .

[0006]

An object of the present invention is to solve the problems associated with the prior art as described above. The present invention is applicable to line production in factories and the like, and can reduce the number of steps and the uniformity of aggregate. An object of the present invention is to provide a decorative veneer having a uniform color tone with excellent dispersibility and design.

The present invention can be applied to line production in factories and the like, and can produce a decorative board having a uniform color tone with excellent uniform dispersibility and design (aesthetics) in fewer steps. The purpose is to provide such a method.

The coating composition 10 containing (dispersing) the aggregate is roll-coated (not shown) on the convex flat surface 31A.
And hardened to produce the patterned coated film 10A or the patterned decorative board 60B.

Such a decorative panel according to the present invention is applicable to line production in a factory or the like, and this method can produce the patterned decorative panel as described above with simpler steps. <Aggregate-containing coating composition> As the aggregate-containing coating composition used in this case, any of an aqueous type, a solvent type, and a non-solvent type may be used as long as the aggregate type is contained. Pigment components other than aggregates may be a translucent color clear paint containing a pigment, and may be a clear paint containing no pigment or a solvent containing no pigment. Varnish, and the curing method may be any of UV curing, heat curing, and room temperature curing.

The water-based paint (water-based paint) preferably used in the present invention is dispersed in water or water and a small amount of an organic solvent.
Dilutable paint, paint binder
Is used in the form of an emulsion, dispersion, aqueous solution, powder suspension (slurry) or a complex type thereof, preferably in the form of an emulsion.

As the resin component in such a water-based paint, conventionally known resins such as an acrylic resin, a vinyl acetate resin, a urethane resin, an epoxy resin, and an alkyd resin can be used.

As the dispersion (diluting) medium, water or a small amount of water [Example: 20 parts by weight or less per 100 parts by weight of water]
And a dispersion medium comprising an organic solvent. For example, an acrylic resin for a water-based paint is, for example, an acrylic monomer in water in the presence of a surfactant or an acrylic monomer and a small amount of a copolymerized monomer (eg, vinyl acetate, maleic ester, acrylic ester, etc.). It is obtained by emulsion polymerization, for example, has a particle size of about 0.1 to several μm, and an acrylic resin is aqueously dispersed in a polymerization solution.

The vinyl acetate resin for the water-based paint is, for example,
As a monomer, vinyl acetate, or a copolymerizable monomer containing vinyl acetate and a double bond (eg, ethyl acrylate,
It is obtained by emulsion polymerization of dibutyl maleate, vinyl alcohol ester, ethylene and the like in an aqueous solution containing a protective colloid (eg, polyvinyl alcohol, hydroxymethyl cellulose) in the presence of a catalyst.

Such an aqueous paint may further contain various additives such as a coloring pigment, an extender, a thickener, a dispersant, an antifoaming agent, a film-forming aid, and a preservative, if necessary. Is also good. As the solvent-based coating, any conventionally known type such as thermosetting and thermoplastic may be used. As the thermosetting type solvent-based coating, a hydroxyl group-containing ethylenically unsaturated monomer (for example, 2 -Hydroxyethyl (meth) acrylate) (co) polymers, melamine resins and thermosetting acrylic resin coatings containing polyisocyanate and the like. As the thermoplastic type solvent-based coatings,
Acrylic lacquer and the like can be mentioned.

Examples of the solventless resin include a UV-curable unsaturated polyester resin, epoxy resin, (meth) acrylic resin, urethane resin and the like. In any of these paints, additives such as the above color pigments may be blended.

<Aggregate> The coating composition used in the present invention contains an aggregate. As the aggregate, as described above, the aggregate is mica, silica sand, glass beads, crushed glass, or the like. , Glass powder and one or more of these colored materials. In order to improve the design properties of the patterned coating film and decorative panel of the present invention, it is preferable that a colored aggregate is contained, and further it is preferable that colored mica and / or colored silica sand be contained, particularly natural Alternatively, it is preferable that artificial colored foil mica is contained.

The average diameter of the plane of the aggregate used in the present invention is 0.1 to 5 mm, preferably 0.5 to 2.5 mm, more preferably 0.5 to 1.5 mm. When an aggregate such as foil mica or silica sand having such an average diameter is used, there is no roughness due to the foil shape, and each color pattern tends to be clear.

The number of colors of the colored mica is usually from 1 to 10, preferably from 2 to 4. If the number of colors exceeds 10, the color tone tends to be cloudy and the sharpness tends to be lost. Among such aggregates, especially in a coating composition containing mica or silica sand, even when a shearing force is applied to the composition during coating, the uniform dispersibility of the aggregate is not destroyed, and the coating film is not damaged. Aggregates such as colored mica will be distributed evenly in the interior, and the convex part of the substrate to be coated will have uniform color tone, lightness, saturation, gloss, etc., and makeup with a pattern such as stone texture A plate is obtained.

The following are examples of (colored) mica. Color mica manufactured by Mica Yamaguchi Corporation: HC-938
9 white (average diameter 1.0 mm), HC-9372 black (average diameter 1.0 mm), etc. Mica made from axillary mica: mica white 13 (average diameter 1.0 m)
m), black 13 (average diameter 1.0 mm) and the like.

In particular, a coating composition containing these mica is preferable because an excellent stone-grain pattern can be obtained. In the present invention, these aggregates can be used alone or in combination of two or more.

Such an aggregate is usually contained in an amount of 20 to 200 parts by weight, preferably 40 to 100 parts by weight, based on 100 parts by weight of the resin solid content in the coating composition. desirable. It is preferable that the aggregate be contained in such an amount because the aggregate is distributed over substantially the entire surface of the convex surface of the substrate to be coated.

In the present invention, conventionally known "other coloring materials" may be used together with such aggregates. Examples of such a coloring material include pigments and dyes of various colors such as red iron oxide, yellow, and gray. Other coloring materials, such as petals, have a resin solids content of 100% in the coating composition.
Usually, 1 to 50 parts by weight, preferably 5 parts by weight,
Up to 20 parts by weight may be included.

<Substrate to be Coated and Coating Method> Substrate to be Coated 5
As 0, the material is not particularly limited as long as it has uneven surfaces 21 and 31 on its surface, or has uneven surfaces 20 and 31A on the surface of the undercoat layer 6 on the substrate 50 to be coated. For example, resin, wood, metal, slate, calcium silicate plate, wood chip cement plate and the like can be mentioned, and the external shape is not particularly limited, such as a substantially plate shape, a sheet shape, a nonwoven fabric shape, and a three-dimensional shape.

In the present invention, the coating composition containing such an aggregate is applied to the surface of the above-mentioned substrate by a roll coater. The viscosity at the time of application (measured with a Stormer viscometer) is as follows. Although it depends on the distance between adjacent concave portions and the distance between convex portions on the surface of the substrate to be coated, the depth of the concave portions and the like, and is not determined unconditionally, it is usually 40 to 90 ku, preferably 50 to 8
It is preferably 0 ku. When the viscosity is less than 30 ku, the whole becomes the same color by casting over the entire uneven portion of the substrate to be coated, and there is a tendency that a patterned substrate of two or more colors tends not to be obtained. However, the fluidity tends to decrease and the coating efficiency tends to decrease.

In the present invention, the coating composition having such a viscosity is used in an amount of usually 20 to 70 m / min, preferably 30 to 50 m / min.
It is desirable to paint at a speed of minutes. In addition, such a coating composition is used in an amount of 0.5 to 4.0 g / size at one time.
² [5.5-44 g / m ² ], preferably 1.0-3.0
/ Scale ² [11-33 g / m ² ]. The thickness (total) of the cured film formed by repeatedly applying and curing the coating composition once to several times is not particularly limited, but is usually 5 to 50 μm, preferably 10 to 10 μm.
It is about 25 μm thick. In addition, the curing method of the coating composition applied in this manner differs depending on the type of the coating material used and the like, and is not determined unconditionally.
Examples of the method include curing.

In the present invention, as shown in FIG. 1, the coating composition 10 containing the aggregate is applied directly to the convex flat surface 31 of the base material 50 to be coated by a roll coater (not shown). The patterned coating film 10 and the patterned decorative plate 60A may be manufactured (FIG. 1).

For example, as schematically shown in FIG.
The substrate 5 to be coated can be formed by various known coating methods (eg, spray coating, electrostatic coating, brush coating, dip coating, etc.).
The sealer 1, the intermediate paint 3, the entire surface of the substrate 50 to be coated including the zero concave plane 21 and the convex plane 31.
Each of the coating films 1, 3, and 5 may be formed by sequentially applying the topcoat paint 5 and curing as necessary. In addition, the coating film 5 is the coating film 3
The color tone may be changed, and only the protrusions may be painted with a roll coater to give a two-tone color.

In the present invention, after the undercoating is performed as described above, the above-described coating composition 10 may be applied with a roll coater to manufacture the decorative board 60B with a pattern. In addition,
The roll coater used is preferably a soft sponge-like roll coater.

When coated in this manner, as shown in FIG. 2, the coating composition 10 does not adhere to the concave portions 20 of the coating film made of the above-mentioned top coating material 5, but adheres only to the convex portions 30. Therefore, in FIG. 2, the color tone of the concave portion 20 of the coating film made of the top coating material 5 and the color tone of the convex portion 30 of the coating film of the coating composition 10 appear. Therefore, according to the method of the present invention, a feeling of material such as a deep tile tone or a stone grain tone appears strongly.

As the undercoat paint used at this time, conventionally known paints such as a solvent-based acrylic resin and a water-based acrylic resin emulsion as described above can be used. Further, the application speed of the undercoat paint and the thickness of the undercoat cured layer 6 obtained by applying and curing the undercoat paint are not particularly limited as long as the uneven surfaces 20, 31A as shown in FIG. However, for example, the thickness is about 10 to 120 μm, preferably about 40 to 80 μm.

The preferred combinations of (a) substrate to be coated / (b) undercoat layer / (c) colored mica-containing coating composition layer in the present invention are as follows: (a) Nichiha siding board for outer wall / (B) Colored mica-free water-based acrylic emulsion paint layer / (c) Colored mica-containing water-based acrylic emulsion paint layer, (a) Kubota siding board / (b) solvent-based acrylic resin paint layer / (c) colored mica-containing Water-based acrylic emulsion resin paint layer, (A) Nichiha siding board / solvent-based acrylic resin paint layer / colored mica-containing solvent-based acrylic silicone resin paint layer.

[0047]

The patterned coated film and decorative panel according to the present invention are full of realism, such as stone-grained, tile-like and mosaic patterns.

According to the method for producing a patterned coating film and a decorative panel according to the present invention, the aggregate contains, for example, foil-like colored mica (color mica) having an average (flat) particle size of about 1 mm. Nevertheless, by roll coater painting,
A multi-colored coating film or a multi-colored decorative board in which the aggregate is uniformly dispersed can be easily obtained with fewer steps than before. Moreover, in this method, even if the production line is operated in a factory or the like for a long time to produce the patterned coating film or the decorative panel, the stability of the pattern can be maintained, thereby improving the productivity and reducing the cost. Can be planned.

In addition, according to the present invention, by applying an aggregate-containing coating composition to a substrate having irregularities using a roll coater, the aggregate can be uniformly applied only to the projections. And a multi-colored coating film of several colors (1 color or more and 10 colors or less) can be formed by such a method.
