[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention particularly relates to a method for producing visually superior decorative patterns on interior and exterior materials of buildings.

0002

[Prior Art] Interior and exterior materials for buildings include, for example, plywood, fiberboard, gypsum board, asbestos cement board, calcium silicate board, pulp cement board, wood wool board, composite board, extruded cement board, Various materials such as metal plates are used.

Furthermore, natural stone materials such as granite and marble have also been widely used. However, in recent years, these natural stones have been decreasing in number, and artificial stones such as ceramic materials such as glass have been used instead. These artificial stones are required to have the excellent solidity that conventional natural stones have, but on the other hand, they also have characteristics that natural stones do not have, such as being translucent or having an excellent visual appearance due to reflected light. is being developed. A typical example is crystallized glass. Crystallized glass is a polycrystalline material obtained by heating amorphous glass.

[0004] Crystallized glass is translucent, and its countless crystal faces diffuse and reflect light in all directions, giving it a deep and soft appearance. In addition, it has high strength, weather resistance, and waterproof performance, is a noncombustible material, and has low thermal expansion that prevents thermal cracking.It can be cut with a glass cutter, and it can also be processed by chamfering, bending, etc. Free and easy. There are two types of commercially available crystallized glass: flat plates and curved plates, which are used as interior and exterior plates.

At present, as described above, this crystallized glass is used as it is as an interior and exterior panel, and also as an interior and exterior panel by coating the surface with fluorescent paint. In this case, it exhibits a visually excellent appearance depending on the color tone and pattern of the applied fluorescent paint. And especially artificial lights on the surface side,
The effect is further increased by providing lighting such as sunlight.

[0006]

[Problems to be Solved by the Invention] Although the color tone of crystallized glass is basically white, various color tones are required depending on the place of application. In addition to color tone, beautiful patterns and shine are also desired. Currently, crystallized glasses with various colors and patterns are commercially available. When used as an interior product, the appearance after sintering will vary depending on the blending ratio of the raw materials used during manufacturing, and as a building material product including luxury interiors and exteriors, it will have an elegant atmosphere. Crystallized glass is highly expected to be a growth product in the future.

Even though marble, granite, crystallized glass, and the like have various patterns on their inner surfaces, the appearance of these patterns is currently limited to their outer surfaces. For example, only the surface crystals of the substrate are exposed by external illumination such as artificial light or sunlight. For this reason, there is currently no method to make internal crystals appear on the surface of the base material, such as in crystallized glass, and the problem is that the crystal structure (composition) inside the base material is not utilized. .

[0008] In recent years, fluorescent paint has been applied to the surface of the base material,
A method of illuminating the surface side with artificial light, sunlight, etc. is adopted, and it has a visually excellent appearance depending on the color tone and pattern of the fluorescent paint applied. Interior and exterior panels coated with this fluorescent paint are excellent for practical purposes, but as buildings have become more upscale in recent years, the interior and exterior panels coated with this fluorescent paint have become more visually appealing and decorative. It has become a strong demand. Furthermore, this fluorescent paint has problems with durability and light resistance when used outdoors, so it deteriorates and fades within a few years. Furthermore, when used indoors, dirt adheres to the paint surface, etc., resulting in poor aesthetics. In any case,
External lighting is required, and crystals and designs inside the substrate are not exposed on the surface of the substrate.

[0009] As a result of research aimed at meeting the requirements already described, the present inventors placed a light source, such as a black light, on the coating side of the transparent substrate coated with the fluorescent coating described above, and The present invention was completed based on the knowledge that when light is irradiated on the substrate, the surface opposite to the surface coated with the fluorescent paint exhibits a visually superior appearance that has not been seen before.

00010]

[Means for Solving the Problems] That is, the present invention applies a fluorescent paint to the surface of a translucent base material, and irradiates the coated surface with a black light from outside the coated surface to make the base material fluorescent. This invention relates to a method for creating a visually superior decorative pattern in accordance with the applied fluorescent paint and the crystals inside the base material on the opposite side of the paint-applied surface. Since crystallized glass is practically excellent as a light-transmitting substrate, the present invention will be explained using crystallized glass. The crystallized glass may be one that is commercially available in the world, and an example of the crystallized glass composition is shown in Table 1, and various properties are shown in Table 2.

[Table 1]

[Table 2]

In the method of the present invention, a fluorescent paint is applied to one side of the crystallized glass (the side where the light source is located). In this case, a pattern may be provided in advance on the coated surface by, for example, sandblasting, if necessary. Fluorescent paints are usually organic fluorescent pigments that have bright colors. If necessary, a specific pattern can be provided in advance by sandblasting or the like on the crystallized glass surface to which the fluorescent paint is applied.

[0012] The thickness of fluorescent paint application is usually 50 mm in practical terms.
~200 μm.

[0013] The color and sharpness of the fluorescent paint differ depending on the pigment used, and the fluorescent color also differs depending on the light source used to irradiate it. That is, it exhibits different fluorescent colors depending on daylight, fluorescent lamp light source, mercury lamp light source, sodium lamp, black light lamp, etc. The inventors conducted research on various light sources and selected a black light lamp. The black light lamp is a low-pressure mercury lamp that emits only ultraviolet light with a wavelength of 330 to 370 nm and hardly any light. When a fluorescent paint is irradiated with long-wavelength ultraviolet light with a main wavelength of 3650 Å from a black light in a dark place, a fluorescent color with a neon-like shine can be obtained.

As in the present invention, when a fluorescent paint is applied to one surface of the crystallized glass and a black light is irradiated to the coated surface from the coated side, the fluorescent paint fluoresces and becomes more visible than the other surfaces of the crystallized glass. When looking at the glass, one can see colors and forms with fantastic depth and depth through the crystallized glass. This is because the fluorescent light is refracted in various ways when passing through the crystallized glass, revealing the internal design of the crystallized glass. The fluorescent colors visually confirmed by the method of the present invention exhibit various colors by changing the type of fluorescent paint.

[0015] Polycrystalline glass is best as a translucent substrate, but it is not limited thereto. The method of the present invention can be applied to various interior and exterior materials for buildings, and can also be used for various information boards, exhibition displays, product displays, hotels, wedding halls, restaurants, discos, events, etc.

Next, the present invention will be explained with reference to examples. Example 1 Fluorescent paint Lumilite Color (manufactured by Shinroihi Co., Ltd.) red was applied to the back side of the 400 x 600 x 7 mm crystallized glass flat plate (manufactured by Otake Ceram Co., Ltd.) Athena Veil to a thickness of 1.
It was applied to 20μ. This coated surface was irradiated with black light beams (long wavelength ultraviolet rays with a main wavelength of 3650 Å). As a result, the surface of crystallized glass has brightness, color tone, and luster that have not been visually seen before, and it has a fantastic, deep color (reddish color) and design that cannot be adequately expressed in words. was gotten.

Example 2 The same process as in Example 1 was carried out except that a flower pattern was formed by sandblasting before applying the fluorescent paint to the back surface of the Athena veil. As a result, as in Example 1, a flower pattern with a visually excellent color (reddish) and a visually unprecedented characteristic appeared on the surface of the crystallized glass.

[0018]

[Effects of the Invention] The present invention applies a fluorescent paint to the back side of a transparent substrate such as crystallized glass, and irradiates the coated surface with a black light to create a design on the surface of the substrate such as crystallized glass. This will expand its use as a building material for interior use. Compared to conventional construction methods, the method of the present invention has no problems with outdoor light resistance or durability.
Problems such as dust adhesion on interior surfaces are also solved, and furthermore, there is no need for external lighting. Furthermore, as in the method of the present invention, the color that appears on the surface of a translucent substrate such as crystallized glass by light irradiation from the back side is more fantastic and deeper than the color that appears when the front surface is irradiated. , and has depth, expanding its use as interior decoration.
