Description

TECHNICAL FIELD [0001] The present invention relates to a coating material, a coating material layer, and a laminated structure,

The present invention relates to a novel coating material, a coating material layer, and a laminate (coating) structure. The present invention can be applied mainly to buildings and civil engineering structures.

Background Art [0002] Conventionally, natural stone is widely used as a surface cosmetic material in buildings and wall surfaces of civil engineering structures. With such a material, it is possible to express beauty with depth that is unique to a natural product. However, natural stone is disadvantageous in that it is expensive, difficult to process, and has a high weight. Particularly, it is difficult to process and has a high weight, which may adversely affect workability and safety when applied to a wall surface or the like.

Under these circumstances, various methods have recently been proposed for obtaining a finish of natural stone by porcelain. For example, Japanese Patent Application Laid-Open No. 11-130980 (Patent Document 1) discloses a composition containing an aggregate having a particle diameter of 0.05 to 5 mm and an acrylic resin emulsion containing a silicon atom in a resin skeleton. Japanese Patent Application Laid-Open No. 2000-15999 (Patent Document 2) discloses a ceramic material in which colored aggregates having a uniform particle size within a range of 10 to 1000 占 퐉 are mixed and dispersed in a colorless transparent binder. However, since such porcelain is mainly composed of aggregate, the specific gravity of the material is relatively large. In addition, the amount required for coating is relatively large, so there is a limit in weight reduction.

On the other hand, Japanese Patent Application Laid-Open Nos. 5-237444 (Patent Document 3) and 2005-238138 (Patent Document 4) disclose that a plurality of colored paints of different colors are spray painted to form a natural stone pattern Method is disclosed. This method is advantageous in terms of weight reduction compared with the techniques of the above-described Patent Documents 1 and 2. [

However, in the methods of Patent Documents 3 and 4, since a plurality of paints are required, the painting work becomes complicated and it is difficult to reproduce a predetermined shape. In addition, the shape to be formed tends to give an artificial impression, and it is difficult to obtain a deep feeling unique to natural stone. In addition, the shape surface obtained by this method may cause a rise in temperature due to sunlight or the like.

The surfaces of these base materials 1 may be subjected to any surface treatment (for example, a sealer, a spacer, a filler, a putty, etc.), or may have a coating film or a wallpaper attached thereto. The base material 1 may be flat or irregular.

On the surface of the substrate (1), a colored layer (2) is formed. The colored layer 2 can be formed by applying a coloring material to the base material 1. Such a coloring material may be uniformly coated on the entire surface of the substrate.

As the coloring material, a mixture of the color materials and the coloring materials may be used. Among these resins, an acrylic resin, a urethane resin, a vinyl acetate resin, a silicone resin, a fluorine resin, an acrylate vinyl resin, an acryl urethane resin, an acrylic silicone resin and the like can be used. . The form of the resin is not particularly limited, but a water-dispersible resin (resin emulsion) is suitable.

As the respective color granules, the above-mentioned chromatic color granules, black granules, achromatic granules and the like can be used. The color tone of the coloring material can be prepared by appropriately setting the kinds and ratios of these coloring materials. The proportion of the powdery material is preferably 5 to 500 parts by weight, more preferably 10 to 400 parts by weight, based on 100 parts by weight of the resin solid content.

The coating (laminate) structure of the present invention has a covering material layer 3 on the colored layer 2. This covering material layer 3 is composed of two or more kinds of colored colored particulate materials, and as a colored particulate material, a transparent colored particulate material having the same color as that of the material layer is colored. The covering material layer 3 may be a discontinuous coating film. The particle diameter of the transparent colored particulate material is preferably 0.1 to 15 mm, more preferably 0.5 to 12 mm, and still more preferably 1 to 10 mm.

In the present invention, " the same color " means that the color can be visually recognized as almost the same color. Concretely, the mutual color difference is usually 5 or less (preferably 4 or less, and more preferably 3 or less). This color difference? E is calculated by measuring color data (L *, a *, b *) of the object (the surface portion of the colored undercoat layer and the portion of the colored undercoat layer on the colored undercoat layer) . The color difference can be measured using a color difference meter.

On the other hand, " dichroic " means that the color can be visually recognized as a different color, and the color difference thereof is usually more than 5 (preferably 6 or more, more preferably 8 or more).

In the present invention, by including the transparent colored particulate material in the covering material layer 3, transparency, depth and the like are imparted, and a large pattern shape is obtained. Such an effect is considered to be exhibited by a visual action that is the same color as the material layer even when the colored particulate material is transparent and colored.

The covering material layer 3 can be formed by the following method (1) or (2).

(1) A coating material in which at least two kinds of colored particulate materials of different colors (at least one or more of the colored particulate materials are transparent colored particulate materials in which a transparent coloring material is granulated) is dispersed in an aqueous medium is applied.

As the transparent coloring material, it is preferable to form a transparent colored film having a concealment rate of 80% or less (preferably 5 to 70%, more preferably 10 to 60%, and more preferably 15 to 50%). These characteristics contribute to imparting a sense of transparency, depth, and a large pattern. When the transparency of the transparent coloring material is insufficient, such an effect can not be obtained well.

As the colored particulate material other than the transparent colored particulate material, an opaque coloring material which is more granular than the transparent coloring material can be used. Such a coloring material may comprise the component (a), the component (b), and the like, but the covering ratio of the coating is preferably more than 80% (more preferably 85% or more, 90% or more). In consideration of these conditions, the coloring material can be obtained in the same manner as the transparent coloring material.

The coating amount of the covering material is preferably 0.1 to 1 kg / m ² , more preferably 0.2 to 0.8 kg / m ² . Drying after coating is usually carried out at normal temperature, but it is also possible to perform heating.

In the above (2), a coating method capable of granulating the coloring material (transparent coloring material) at the time of coating can be employed, and spray painting is particularly suitable. These coloring materials may be applied simultaneously or sequentially. When a plurality of kinds of coloring materials are simultaneously coated, a double-headed spraying paint or the like can be used as a coating mechanism. The application amount of the coloring material is preferably 0.01 to 0.8 kg / m ² .

The coating material layer 3 has some irregularities. The dry film thickness of the convex portions is preferably 50 占 퐉 or more, more preferably 100 占 퐉 or more, further preferably 300 占 퐉 or more, particularly preferably, 500 탆 or more. The upper limit of the dry film thickness of the convex portion is preferably 2000 占 퐉 or less, more preferably 1800 占 퐉 or less, and still more preferably 1500 占 퐉 or less. In the present invention, even if the covering material layer 3 is a relatively thick film, sufficient design effect can be obtained in terms of transparency, depth, and the like. The dried film thickness of the convex portion was measured in the same manner as in the first invention group.

The covering material layer 3 contains at least one transparent colored particulate material, but it preferably contains two or more kinds (preferably three or more kinds) of transparent colored particulate materials having different color tones. That is, it is preferable that two or more transparent coloring particulate materials (preferably three or more colors) are mixed. The proportion of the transparent colored particulate material in the colored particulate material is preferably 20 to 100% by weight, more preferably 50 to 95% by weight.

As a method of molding the laminated structure of the present invention into a sheet form in advance, a known method may be employed. For example, the colored layer 2, the covering layer 3 and, if necessary, the transparent layer 4 may be coated on the supporting layer 5 by the above-described method. In each layer, the respective materials described above can be used.

In Fig. 2, a sheet-like laminated structure in which a colored undercoat layer 2 and a cover material layer 3 are laminated is used on a support layer 5.

Examples of the support layer 5 include a woven fabric, a nonwoven fabric, a ceramic paper, a synthetic paper, a glass cloth, a mesh, a gypsum board, a plywood, a slate plate and a metal plate. The support layer 5 may be made of two or more kinds of materials. As the support layer 5, those having infrared reflective properties, heat insulating properties and the like can also be used.

The sheet-like laminated structural body may be handled as a sheet-shaped formed body at the time of distribution, and the sheet-like laminated structural body may be fixed to various substrates 1 after being brought into a construction site such as a building or civil engineering structure. When the sheet-like laminated structure is fixed to the substrate 1, an adhesive, an adhesive, an adhesive tape, a nail, a pushpin, a pin, a fastener, a rail, or the like can be used.
