Description

[Detailed Description of the Invention] The present invention relates to a construction panel with improved surfaces of exterior materials and interior materials in buildings, so-called decorative surfaces.

In general, decorative surfaces of architectural members, especially interior and exterior materials, are required to have fashionability. And for this,
This has usually been dealt with by changing color or external shape. However, no matter how much the colors were changed in metal plates, it was still impossible to create a three-dimensional effect, so-called solidity, and depth. As an improvement over this, a product with so-called ricin finish, which is adhered to the surface of an iron plate, is commercially available. This product improved the above-mentioned drawbacks somewhat better than the iron plate itself, but it was not sufficient.

Furthermore, when forming an uneven patterned surface on the decorative surface of plasterboard, calcium silicate board, lightweight concrete board, calcium carbonate board, etc. in order to meet the above requirements, simply forming unevenness on the same material will not enhance the three-dimensional effect. It didn't work that effectively.

In order to eliminate such drawbacks, the present invention has a hard base material with an uneven patterned surface, especially a depressed patterned surface deep enough to bury the colored sand, and the colored sand is fixed only to this uneven patterned surface. A transparent paint is applied to the decorative surface to cover the uneven patterned surface to create an optical effect composed of a hard base material, a concave patterned surface made of a different slightly undulated surface, and a convex patterned surface that is a specular reflection surface. We propose an architectural panel that has a rich three-dimensional effect due to its surface structure.

An embodiment of the architectural panel according to the present invention will be described in detail below with reference to the drawings. Figure 1a,
1 is a perspective view and a vertical cross-sectional view showing an example of a construction panel according to the present invention, and 1 is a hard base material such as a metal plate made of a surface-treated steel plate, an aluminum plate, a stainless steel plate, a copper plate, etc. (as shown in figure a). ) or an inorganic hardened board (shown in Figure b) made of the above-mentioned lightweight concrete board, gypsum board, calcium carbonate board, etc., with uneven pattern surfaces 3 and 4 on the surface that will become the decorative surface 2.
has.

The decorative surface 2 has a concave pattern surface 3 and a flat top surface 4a.
and a side wall 4b from the edge of the concave pattern surface to the top surface 4a are formed continuously, independently, or randomly. The difference in height of this uneven patterned surface, the so-called depth h, is the depth at which at least all of the colored sand described later is buried. The best depth is one at which all of the colored sand is buried and some gap is formed between it and the top surface of the convex pattern. 5
has the function of at least temporarily fixing only the lower part of the colored sand described below to the concave pattern surface 3 as a fixing layer. Provided on the side wall 4b. The color of this fixed layer is considered in relation to the hard base material 1 and the colored sand depending on whether it is colorless or colored. For example, there are various combinations, such as using a colorless adhesive for the adhesive layer if the underlying color, the so-called hard substrate, is black, or using a cream-colored adhesive if the underlying material is white. The fixing layer fixes the colored sand at least temporarily, and is formed to have a thickness of several microns, for example. Of course, it is also possible to form it thicker as required. The above-mentioned synthetic resin paints include paints whose main components are phenolic resins, polyurethane resins, acrylic resins, polyester resins, alkyd resins, and other well-known resins. 6 is colored sand, and its materials include silica sand, shirasu, crushed stone (marble, quartz, Oya stone, and other stones), bentonite, talc, diatomaceous earth, perlite,
An organic or inorganic coloring agent is applied or coated on the outer periphery using permiculite, calcium carbonate, glass, or the like. As the coloring agent, dyes and the like are used for organic systems, and pigments for coloring are used for inorganic systems. For example, synthetic organic pigments, azo dyes, anthraquinone dyes, titanium, carbon black, cobalt blue, cadmium yellow, vermiculite green, aluminum powder,
and various coloring agents. Also, the size of the colored sand,
Although the shape is not particularly limited, it is determined by the relative relationship with the depth of the concave pattern surface described above. For example, if h = 0.3 to 0.5 mm, colored sand with a grain size of 0.3 to 0.4 mm, if h = 0.7 mm, colored sand with a grain size of 0.6 mm, and if h = 1 mm, colored sand with a grain size of 0.8 mm. Colored sand with a grain size of mm to 0.9 mm; if h = 2 mm, use colored sand with a grain size of 1.5 mm. Note that a grain size of 28 to 32 mesh is usually used for h=0.7 mm. Furthermore, the colored sand 6 is in a state in which the colored sand 6 is not in contact with each other, as shown partially in an enlarged view in FIG. As shown in some parts, the colored sand etc. 6 are distributed in a dispersed state in which they are in close contact with each other, or in a dispersed state in which there are many parts where the colored sand 6 is in close contact with each other (not shown). Furthermore, the colored sand 6 includes not only a single color but also a mixture of at least two or more colors. 7 is a transparent paint layer that covers the entire surface of the decorative surface 2 as partially shown in an enlarged view in Figure 3. Its main functions are to prevent the color of the colored sand from deteriorating, and to prevent the colored sand from deteriorating. The purpose is to prevent falling off, to obtain a waterproof effect for the hard substrate 1, to obtain weather resistance (rust prevention and corrosion resistance), and to enhance the color and three-dimensional appearance of colored sand by utilizing light refraction. The material for forming the paint layer 7 includes acrylic resin, alkyd resin, acrylic resin, acrylic resin and melamine resin, and other transparent clear resins. The transparent coating layer 7 may be subjected to a polymerization reaction by baking or by natural drying, depending on the purpose. Although the fixed layer 5 and the transparent paint layer 7 are clearly separated in FIG. 3, this is drawn for convenience, and they may be mixed depending on the state of the fixed layer.

What has been described above is only one embodiment of the construction panel according to the present invention, and the shape of the rigid base material 1 can also be formed into a male-female connection structure as shown in FIG. In Fig. 4, 8 is a side wall, 9 is an insertion edge, and 10
11 is an insertion groove, and 11 is a protruding edge, which is useful for forming a wall by male-female connection. Also, translucent paint may be used instead of transparent paint.

The architectural panel constructed as described above has the feature that it is possible to obtain a panel having a decorative surface with enhanced three-dimensional effect by significantly improving the nature of the hard base material itself. A feature that completely changes the image of the essence of the hard base material due to the synergistic effect of the color of the uneven pattern surface and the concave pattern surface, the color of the colored sand of the small undulation surface (diffuse reflection surface), and the color of the specular reflection surface of the convex pattern surface. There is.
It is characterized by fully demonstrating the characteristics of colored sand, improving waterproofness, weather resistance, and corrosion resistance, and preventing colored sand from falling off.
