Abstract

PURPOSE:To improve the design properties of the facing and interior finish, weather resistance, stain resistance, chemical resistance, corrosion resistance, file resistance, strength, etc., of a building and a structure by forming a resin layer between a metal plate and a glass layer and unifying the metal plate, the glass layer and the resin layer. CONSTITUTION:A resin layer 2 such as polyethylene, polypropylene, a vinyl chloride resin, etc., is interposed between the metal plate 1 of iron, aluminum, copper, stainless, titanium, etc., and a glass layer 3, and unified. Even when the glass layer 3 is damaged, a simultaneous falling of the whole part of the layer 3 is prevented. Accordingly, a decorative laminate A can be formed in a large size while design properties, weather resistance, strength, etc., are improved by positioning the glass layer 3 to a surface, and the adhesion of dust is prevented and cleaning can also be simplified.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is used, for example, in exteriors or interiors of buildings, structures, etc., and has unprecedented designability, weather resistance, stain resistance, chemical resistance, corrosion resistance, fire resistance, strength, etc. The present invention relates to a decorative board which is greatly improved as compared with the conventional one.

2. Description of the Related Art Generally, as a method for improving the design of the surface of a metal decorative plate, a method using lysine as disclosed in JP-B-60-18308 and JP-B-57-27816.
Method by embossing as in Japanese Patent Publication, Japanese Patent Publication Sho 59
There is known a method using a mastic paint as disclosed in Japanese Patent No. 16830.

[0003]

However, this type of method has various drawbacks. That is, in the lysine method, due to the size of the sand, the three-dimensional effect was more than that of the flat surface, and the uniform distribution was difficult. Also, when embossing, there are various restrictions on height, pattern, and material,
The height was about 0.5 mm, the pattern was a pattern in which unevenness was balanced and the coating film was not cracked, and the material was aluminum, which had good workability, a colored iron plate, or the like. Further, in the case of using the mastic paint, it is difficult to uniformly manufacture the pattern, resulting in an increase in cost, and there is a disadvantage that the pattern is peeled off. Further, these are liable to attach dust and are very difficult to clean, and are inferior in designability, weather resistance, stain resistance, chemical resistance, corrosion resistance, fire resistance, strength and the like. Further, these are tired of their design, and it has been expected that a decorative board having a novel appearance that has never existed will be put on the market.

[0004]

In order to eliminate such drawbacks, the present invention forms a resin layer between a metal plate and a glass layer and integrates them, thereby designing an exterior or interior of a building or a structure. The present invention proposes a decorative board having improved properties, weather resistance, stain resistance, chemical resistance, corrosion resistance, fire resistance, strength and the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a decorative board according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is an enlarged cross-sectional view showing a part of a decorative plate according to the present invention, where A is a decorative plate, 1 is a metal plate, 2 is a resin layer, and 3 is a glass layer.

More specifically, the metal plate 1 is made of iron, aluminum, copper, stainless steel, titanium, aluminum / zinc alloy plated steel plate, enamel steel plate, clad steel plate, laminated steel plate (vinyl chloride steel plate, etc.), sandwich steel plate (damping steel plate, etc.). Etc. (including, of course, colored metal plates coated with these in various color tones), and may be formed into various shapes by roll molding, press molding, extrusion molding or the like, if necessary.

Further, the metal plate 1 functions as a base and a protective material integrated with the glass layer 3 which will be described later, and is integrated with the metal plate 1 even if the glass layer 3 is damaged by an external force. Therefore, the glass layer 3 does not drop at a stretch, and the danger can be prevented. Therefore, the decorative plate A can be formed in a large size.

The resin layer 2 is made of polyethylene, polypropylene, polystyrene, vinyl chloride resin, styrene resin, methacrylic resin, polyurethane, phenol resin,
Urea resin (urea resin), melamine resin, fluororesin,
It is a sheet-like member made of one or more of silicon resin, fiber reinforced plastic, and the like.

As a matter of course, in the resin layer 2, as a pigment, an inorganic pigment having talc, kaolin, titanium oxide, zinc oxide, iron oxide or the like as a main component, a natural pigment, an organic pigment, or a pigment made of ceramic color powder or the like. Is added and colored to form various color tones and patterns.

Further, when the resin layer 2 is formed with a color tone, a pattern or the like so as to have an appearance such as a raster tone (rainbow finish), a metallic tone, a pearl tone, or a seven-color rainbow color tone, the glass layer 3 described later is formed. Refractive index (polarization index)
With the synergistic effect of and, there are unprecedented colors and textures, and the impression of the viewer will remain large. Of course, the resin layer 2 may function as an adhesive agent between the metal plate 1 and the glass layer 3. Of course, the color tone may be changed depending on the viewing angle.

The glass layer 3 is mainly made of ordinary transparent glass, and the appearance of the resin layer 2 changes depending on the difference in the thickness and the refractive index (polarization index) thereof.
The appearance of the resin layer 2 changes depending on the viewing angle, so that the decorative board A has a design that is unprecedented.

The material is a hard and brittle transparent body containing silicate as a main component. Generally, silicic acid, boric acid or the like is used as the acid component, and soda, potassium, lime, or the like is used as the base component.
Lead oxide etc. are crushed and kneaded, and this is put in a furnace at 1400 to 1500
It can be melted at ℃, and various glass products can be made from this seed glass according to the application.

As the glass layer 3, ordinary plate glass (transparent plate, sliding plate glass), float plate glass, polished plate glass,
It is composed of template glass, netted glass, special glass (laminated glass, tempered glass), and the like. In addition, if a polarizing glass that is transparent or invisible depending on the viewing angle is used, the decorative plate A has an appearance that has never been seen before. Of course, the product is obtained by forming the decorative plate A by changing the glass layer 3 according to the purpose of use of the decorative plate A.

Further, since the glass layer 3 is flat and smooth,
Dust is hard to adhere and it is easy to clean. Furthermore, since the glass layer 3 is inorganic, it has fire resistance.

Of course, since the glass layer 3 itself has hardness (shape retention), it is not necessary to give hardness to the material of the metal plate 1, and particularly the metal plate 1 having a large plate thickness or the expensive metal plate 1 is required. No need to use.

Further, the glass layer 3 has weather resistance, stain resistance, and
Since the metal plate 1 has properties such as chemical resistance, corrosion resistance, and fire resistance, the metal plate 1 does not have to have these properties and be expensive.

As described above, simply by adhering to the conventional metal plate 1, the decorative plate A has the advantages of glass (high hardness) and the advantages of metal (toughness).

In order to integrate the resin layer 2 with the metal plate 1 and the glass layer 3, if the resin layer 2 itself has adhesiveness, this is also used, but a transparent adhesive (transparent clear, etc.) is used. It is used and integrated to prevent the resin layer 2 from being hidden by the adhesive. Of course, the resin layer 2, the metal plate 1, and the glass layer 3 may be integrated by heat fusion.

[0019]

Other Embodiments The above description is merely one embodiment of the decorative board A according to the present invention, and it can be formed as shown in FIGS. 2 (a) to 2 (c). That is, (a) is a decorative plate A in which the resin layer 2 is integrally formed by heat fusion between the metal plate 1 and the glass layer 3, and (b) is a resin plate 2 which is the metal plate 1 or glass (not shown). The decorative plate A formed on the layer 3 and integrated with the adhesive 4 made of clear or the like, (c) shows the decorative plate A in which the metal plate 1, the resin layer 2 and the glass layer 3 are integrated with the adhesive 4. Is.

Further, in FIGS. 3 (a) and 3 (b) (cross-sectional view of FIG. 3 (a)), a decorative plate A in which four surfaces are integrated by a U-shaped frame 5 is shown.
Is.

[0021]

As described above, according to the decorative board of the present invention, the glass layer is used as the surface to improve designability, weather resistance, stain resistance, chemical resistance, corrosion resistance, fire resistance, strength, etc. It becomes a decorative veneer. Since the glass layer is integrated with the metal plate through the resin layer, even if the glass layer is damaged, the glass layer does not drop at a stretch and the strength is improved. The formation of the glass layer improves the weather resistance of the resin layer. Due to the formation of the glass layer, the color of the resin layer changes depending on the direction in which the glass layer is viewed, and the exterior or interior has an unprecedented appearance. When a raster (finish), metallic, pearl, or 7-color rainbow-colored sheet is used as the resin layer, the synergistic effect with the glass layer causes the degree of light hitting the resin layer and the glass The hue changes due to the change in the refractive index (polarization index) of the layer, creating a new color. Because it has a design that has never been seen, it is very noticeable and impressive. It is possible to form a large decorative plate having a glass surface. It becomes a decorative board that can pass the fireproof structure. Dust is hard to attach and cleaning is easy. There are characteristics and effects.
