Description

The present invention relates to a painted material, and relates to a painted material having a speckled pattern suitable for use as, for example, a top plate of a kitchen, a bathroom, a vanity, furniture, etc., a wall surface material, a door surface material, and the like.

The top plate used for kitchens and vanities is used by exposing the surface of the material or the surface of the molded product as it is, and the surface is painted and decorated with colors, patterns, etc. Is being used.
For example, Patent Documents 1 and 2 describe a painted object in which a pattern is expressed by such coating.
The coated material described in Patent Document 1 is configured to include a colored base paint layer painted on the surface of the material and a multicolored pattern layer coated with the colored paint in a spotted manner. Here, the colored base paint layer has the same color as the spotted pattern layer, and specifically, the color tone of the colored base paint layer is lighter than that of the spotted pattern layer.
Further, in Patent Document 2, a transparent paint is applied to the surface of metal, glass, etc., and then a high-viscosity paint is forcibly sprayed with a spray gun to form an irregular pattern in which fine lines and dots are mixed. The painted material that has been attached is shown.

Japanese Unexamined Patent Publication No. 2000-140750 JP-A-2002-45787

The coating material described in Patent Document 1 is intended to improve the design by unifying the color tone balance between the exposed portion of the colored base coating layer and the speckled pattern.
However, in this painted product, a color such as light gray or light brown is used for the colored base paint layer, and a color such as white, ivory, gray, or dark gray is used for the colored multicolored pattern layer to obtain the above-mentioned light color. It is just a color that satisfies the relationship. Therefore, there will be a difference in the appearance of the spot pattern and the colored base paint layer between the spots, but the overall design must be monotonous. Moreover, even if the speckled pattern is diversified, it does not contribute to the design of the painted object, such as a sense of depth and a sense of depth. Furthermore, no positive consideration has been given to materials that change their appearance depending on the viewing angle and the relative position with the light source over the entire surface.

Further, in Patent Document 2, as in Patent Document 1, only the material difference between the patterned portion and the non-patterned portion is expressed.

[Purpose of Invention]
An object of the present invention is to provide a coating material having a variety of designs, such as being able to impart a high-quality feel with enhanced brightness as a whole and expressing different aesthetics depending on the viewing position, angle, and the like. To provide.
Another object of the present invention is to create a clear contrast of shadows between the convex portions forming the speckled pattern and the concave portions between the convex portions, and to make it visible through the metallic layer to give a sense of depth. The purpose is to provide a painted material that can emphasize the feeling of depth and the like.

In order to achieve the above object, the present invention adopts the configuration described in the claims. Specifically, it is configured to include a spot pattern painted on the surface of the object to be painted and a metallic layer painted on the surface of the object to be painted and the surface of the spot pattern.

In the present invention, it is preferable that the surface of the object to be coated is provided in a matte tone. Here, the matte tone is used for those having a glossiness of 60 degrees of 20% or less, preferably 10% or less.

Further, the surface of the object to be coated is formed by applying coating.

Further, a structure in which a transparent layer is further provided on the surface of the metallic layer can be adopted.

In addition, the painted material can be used as a kitchen, bathroom, wash basin, furniture top plate, wall surface material, or door surface material.

According to the present invention, the convex portion of the speckled pattern and the concave portion between the convex portions are painted with the metallic layer, so that the light reflecting material such as aluminum flakes (fine aluminum particles) contained in the metallic layer becomes the convex portion. It is possible to provide a high-quality coating material with enhanced brightness by being oriented so as to imitate the surface of the recess and reflecting light in various directions.
In addition, through the orientation of the light-reflecting material, it is possible to express an aesthetic appearance in which light and darkness differs depending on the viewing position, angle, and the like, and it is possible to provide a painted product having a variety of designs.
Further, if the surface of the object to be coated is matte, it is possible to make the speckled pattern glossy and clarify the contrast of the shadow between the convex portion and the concave portion between the convex portions. In addition, it is possible to make the surface of the object to be painted visible through the metallic layer to make the spotted pattern and the surface of the object to be painted stand out to emphasize the sense of depth and depth.
Further, according to the structure provided with the transparent layer, it is possible to protect the speckled pattern and to express the design property in which the appearance is given a wet color.
In the configuration in which the painted material is applied to the top plate, wall surface material, etc., it is possible to effectively contribute to improving the overall texture of the kitchen or the like to which the top plate or the like is applied.

(A) is a schematic cross-sectional view of the coated material according to the embodiment, (B) is a partially enlarged cross-sectional view thereof, and (C) is a cross-sectional view showing an example of orientation of the light reflecting material in the metallic layer.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The thickness of each layer of the coating material shown in FIG. 1 is shown for the purpose of facilitating the understanding of the specification, and the actual thickness is determined within the range of the numerical values described below.
As shown in FIG. 1, the patterned painted object 10 includes a plate-shaped object to be coated 11, a convex speckled pattern 12 applied to the surface of the object to be coated 11, and the object to be coated 11 and the object to be coated 11. A metallic layer 14 painted so as to cover the surface of the speckled pattern 12 and a transparent layer 16 painted on the surface of the metallic layer 14 are configured.

The object to be coated 11 is not particularly limited, but is composed of a plate-shaped base material 11A and a base layer 11B applied to the base material 11A to form the surface of the object to be coated 11. In the present embodiment, artificial marble is used as the base material 11A, but other resin molded plates, metal plates, wooden plates and the like can be adopted.
The artificial marble constituting the base material 11A is made by coloring a thermosetting resin or a thermoplastic resin with a dye or a pigment, and crushing a plastic material or the like to obtain particles having various colors, shapes, and sizes, as well as artificial ones. It is formed by blending granules obtained by crushing marble, natural stone, etc., and various additives. Examples of the thermosetting resin include polyester resins and thermosetting acrylic resins. Examples of the thermoplastic resin include polyester resin, polyethylene resin, polystyrene resin, vinyl chloride resin and the like.
The preferred plate thickness of the base material 11A in the present embodiment is 1 mm to 50 mm, more preferably 3 mm to 20 mm.

The base layer 11B is provided in a matte tone. As the base layer 11B, a resin component and a coloring pigment mixed and dispersed in a solvent such as thinner and water are preferably used. As the resin component, for example, a thermoplastic resin such as a polyester resin, an acrylic resin, an alkyd resin epoxy resin, a urethane resin, a fluororesin, or a silicon resin, or a thermosetting resin can be used. Further, as the coloring pigment, any pigment capable of coloring the resin component may be used, and various coloring pigments can be used.
The base layer 11B can be applied by an air spray, but may be applied by other means such as a roller.
In addition to painting with a matte paint, the base layer can be roughened with sandpaper or the like to give a matte finish.
The base layer 11B does not necessarily have to be provided. In this case, it is sufficient if the surface of the artificial marble constituting the base material 11A has a matte finish.

Similar to the base layer 11B, the speckled pattern 12 is provided by painting with a paint in which a resin component and a coloring pigment are mixed and dispersed in a solvent such as thinner and water. The speckled pattern 12 is provided over the entire in-plane of the base layer 11B in a state where glossy convex portions are scattered. A concave portion where the base layer 11B is exposed is formed between the convex portions. The size of the convex portion constituting the speckled pattern 12 is preferably 1 mm ^{2 to} 50 mm ² , and the height is preferably 5 μm to 70 μm. This is because if the size of the convex portion is less than 1 mm ² , the pattern becomes inconspicuous and the effect of providing the speckled pattern is reduced, and if it exceeds 50 mm ² , the area balance between the convex portion and the concave portion becomes poor and the design is deteriorated. Is. Further, if the height is less than 5 μm, the contrast of the shadow due to the convex portion and the concave portion becomes inconspicuous, and if it exceeds 70 μm, the surface of the coating material 10 becomes extremely rough, which is not preferable. More preferably, the size of the convex portion is 2 mm ^{2 to} 30 mm ² , and the height is 10 μm to 50 μm.
In [Fig. 1] (A) and (B), the speckled pattern 12 is shown in which the convex portions are independent one by one, but in reality, it is shown in [Fig. 1] (C). As you can see, the convex parts may overlap or connect in the plane direction.
The speckled pattern 12 is preferably applied using a spray gun, but the present invention is not limited to this, and other coating means using a roller or the like can also be used. For example, a method of arranging a masking sheet having a large number of holes corresponding to the convex portions on the base layer 11B, rolling a roller impregnated with paint on the sheet, and then removing the sheet can be adopted. In this case, it is possible to provide a coating material in which the positions of the speckled patterns 12 are standardized or standardized, and the skill level required for spray coating is not required.
The viscosity of the paint of the speckled pattern 12 is adjusted with a viscosity cup NK-2 manufactured by Anest Iwata Co., Ltd. so that the dropping time is 9 to 12 seconds. As a result, when the speckled pattern 12 is applied using a spray gun, a convex portion having the above size and height can be formed without difficulty. It is preferable to adjust the time to 12 to 18 seconds in order to form a large convex portion.
Further, the speckled pattern 12 may be provided by painting with a metallic paint to which a light reflecting material such as known aluminum flakes is added.

In the present embodiment, the metallic layer 14 is formed by using a known metallic paint in which aluminum flakes (aluminum particles) 14A are mixed with a transparent resin. The aluminum particles 14A are generally scaly, and as illustrated in FIG. 1 (C), the longitudinal direction of the scales is oriented so as to follow the upper surface of the convex portion.
The metallic layer can be applied with a thickness of about 2 μm to 15 μm. In order to make the obtained coating material exhibit high brightness as a whole, it is preferable to apply the coating so that 70% or more of the entire convex portions and concave portions are covered with aluminum particles. Further, in order to obtain a sense of depth or depth that can be seen in the depth direction, it is preferable to apply the coating so that 5% or more of the entire convex portion and concave portion can be seen through in the depth direction.

The transparent layer 16 is formed by applying a clear paint using acrylic, urethane, silicone resin, or the like, or a translucent clear paint, thereby protecting the surface of the metallic layer 14 and imparting a wet color. You can do it. In the present embodiment, as the clear paint for forming the transparent layer 16, one to which glass beads 16A are added is adopted, and the surface hardness is increased by the glass beads 16A.

Next, an embodiment will be described.
