[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall material that exhibits a decorative pattern that is particularly visually superior, and a method for creating the pattern using the same wall material.

0002

[Prior Art] Interior and exterior materials used in buildings are required to have improved various physical properties and durability, but in recent years, there has been a strong demand for visually superior design and aesthetics. Became. For this reason, the colors of interior and exterior materials,
Research on patterns, etc. is also being conducted.

[0003] To achieve this objective, coating with fluorescent paint has been put into practical use. Fluorescent paint is a paint with bright colors that uses fluorescent pigments. Fluorescent paint has excellent brightness and color saturation. The above-mentioned fluorescent paints are used by being coated on the surfaces of various base materials. There are various types of base materials, such as vitreous boards, metal boards (iron, stainless steel, aluminum, titanium), cementitious boards (gypsum board, asbestos cement board, calcium silicate board, pulp). Cement boards, extruded cement boards), stone boards (marble, granite, granite), wood boards, synthetic resin boards (vinyl chloride, acrylic, melamine, polyester), etc.

[0004] Fluorescent paints are usually coated on the surface of the substrate with a coating of about 120 to 13
It is coated to a thickness of 0 μm. When the surface of the base material coated with this fluorescent paint is irradiated with various types of light, the coated surface exhibits a beautiful shine, but especially black light (with a wavelength of 3650
When irradiated with long-wavelength ultraviolet light (Å), it exhibits a neon-like glow and is particularly beautiful.

[0005]

[Problems to be Solved by the Invention] There has been an increasing demand for increased decorative value for interior and exterior materials, and in particular there has been a strong demand for them to have a three-dimensional effect.

[0006]

[Means for Solving the Problems] The present inventors completed the present invention as a result of research aimed at developing interior and exterior materials that meet the above requirements. That is, the present invention provides a decorative interior/exterior material for construction, comprising a base material, an inorganic lightweight aggregate layer provided on the base material, and a fluorescent paint applied to the aggregate layer, and the decorative interior/exterior material for construction. This invention relates to a method for producing a visually superior decorative pattern by irradiating it with a black light. All of the base materials mentioned above can be used. That is, they include glass plates, metal plates, cement plates, stone plates, wood plates, synthetic resin plates, and the like. Particularly preferred for practical use are glass plates, metal plates, cement plates, and stone plates, which have a high-quality feel.

Next, lightweight aggregate will be described. Lightweight aggregates include natural stones such as ordinary silica sand and gravel, artificial stones, and by-products, but artificial stones are preferable in terms of quality. Of course, the natural stone described above can also be used satisfactorily. Also, nonflammable ones, white ones, and rounded ones are practical. Among the artificial products, organic products such as polystyrene foam and polystyrene foam have problems in durability and are not nonflammable, making them undesirable for practical use. That is, inorganic lightweight aggregate is suitable.

[0008]As the inorganic lightweight aggregate, all natural stones, artificial materials, etc. can be used as described above, and a typical example is shown below. Perlite is an aggregate made by firing and expanding volcanic glass rock. In Japan, nacre, obsidian, and rosinite are used as raw stones. Although any pearlite may be used, fired obsidian is particularly preferred since it has low water absorption performance. Pearlite naturally satisfies the above conditions, namely, it is lightweight, durable, rounded and non-combustible. Also, the color is generally white.

An example of a fired obsidian product is Fuyolite (manufactured by Fuyolite Co., Ltd.). Fuyolite is a lightweight foam made of crushed and fired obsidian, which is made up of inorganic granular closed-cell aggregates covered with a strong glassy coating. An example of this chemical composition is shown in Table 1.

[Table 1] Examples of the particle size and capacity of this product are shown in Tables 2, 3, and 4.

[Table 2]

[Table 3]

[Table 4]

In the present invention, it is preferable that the particle size is coarse, and the particle size is preferably about 5 mm to 20 mm.

Next, a method for fixing lightweight aggregate to a base material will be described. Usually fixed with adhesive. As an adhesive,
Epoxy resin system, vinyl acetate resin system, chlorobrene (C
R) type, rubber type, acrylic resin type, polyester resin type, phenol resin type, and vinyl chloride resin type. A typical inorganic mortar is a polymer cement mortar made by mixing a synthetic polymer emulsion into Portland cement.

Furthermore, it may be attached using commonly used double-sided tape. Note that polymer cement mortar is preferable in consideration of durability and the like. As described above, a lightweight aggregate layer can be provided on the base material surface. The aggregate layer is 5mm thick
Approximately 20 mm is preferable.

[0013] Next, fluorescent paint is applied to the surface of this aggregate layer so as to form a desired design. As described above, it was possible to produce a decorative interior/exterior material for architecture, which is composed of the base material of the present invention, an inorganic lightweight aggregate layer provided on the base material, and a fluorescent paint applied to the aggregate layer. When the decorative interior/exterior material for architectural use of the present invention was irradiated with a black light, a visually excellent decorative pattern appeared on the exterior material. Furthermore, depending on the unevenness of the aggregate surface and the type of fluorescent paint, it has become possible to create a wide variety of excellent patterns.

【Example】

Stainless steel plate (1000 x 1000 mm□) as an example base material
High mole emulsion (manufactured by Showa Denko Co., Ltd.) was mixed with white cement (manufactured by Nippon Cement Co., Ltd.), an appropriate amount of water was added, and the mixture was applied to the substrate using a brush. Next, on that front, Fuyolite FL7, which is a lightweight aggregate, and Venuslite (
(small) was glued. Next, based on the predetermined design, fluorescent paint Lumilite Color (manufactured by Shinroihi Co., Ltd.) was applied in red, green, and
Five colors, pink, blue, and yellow, were applied to a thickness of 120 to 130 μm. Next, this coated surface was irradiated with black light beams (long wavelength ultraviolet rays with a main wavelength of 3650 Å). As a result, a fantastic, deep, three-dimensional, and deep color was obtained on the surface of the aluminum plate.

Comparative Example Five colors of fluorescent paint Lumilite Color (manufactured by Shinroihi Co., Ltd.) having the same design as in the example were directly applied to a stainless steel plate, and the coated surface was irradiated with a black light beam. Although I was able to obtain a neon-like glow, I was unable to obtain three-dimensional, deep colors.
