Description

[Detailed Description of the Invention] The present invention relates to a construction panel with improved surfaces of houses, particularly interior and exterior materials, so-called decorative surfaces. More specifically, by utilizing the characteristics of a hard base material with an uneven patterned surface, sand grains and reflective particles are distributed in a mixed state only on the uneven patterned surface, the lower part is fixed, and a transparent resin layer is laminated and coated on top of it. This invention relates to an architectural panel that enhances the three-dimensional effect and fully exhibits the effect of reflective grains and sand grains.

In general, decorative surfaces of architectural members, especially interior and exterior materials, are required to have fashionability. In contrast, it has usually been targeted by changes in color or external shape. However, even if the colors of metal plates and the like were slightly changed, it was still not possible to create a sense of confrontation, so-called solidity, or a decorative accent. So, to improve this,
Products with a so-called ricin finish, in which sand is adhered to the surface of an iron plate, are commercially available. This product improved the above drawbacks somewhat better than the iron plate itself, but it was not sufficient. In addition, when forming an uneven patterned surface on the decorative surface of gypsum board, 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 defects, the present invention distributes a mixture of sand grains and reflective grains on the uneven patterned surface of a hard base material, especially on the concave patterned surface, and forms a synthetic resin layer on such a decorative surface to create a decorative surface. This is an architectural panel that attempts to add three-dimensionality and accents to decorative surfaces through a structure that also functions as a protective film that improves the weather resistance of the surface, prevents sand grains from falling off, and prevents performance deterioration in color, reflectance, etc. suggest.

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 slab, calcium carbonate board, etc., and the surface that will become the decorative surface 2 has uneven pattern surfaces 3 and 4.
has. On the decorative surface 2, a concave pattern surface 3 and a convex pattern surface 4 whose top surface 4a is at least somewhat planar are randomly distributed. Note that when the top surface 4a is planar, it functions usefully as a specular reflection and thus contributes to promoting a three-dimensional effect. Further, it is preferable that the height of the uneven pattern surface, the so-called depth h, be somewhat larger than the outer diameter of the sand grains or the like. 5 is a fixing layer which has the function of at least temporarily fixing the sand grains and reflective grains described below only on the concave pattern surface 3, such as synthetic resin paint,
A rubber adhesive or a glue type adhesive is provided on at least the bottom surface of the concave pattern surface or the entire concave pattern surface 3. Depending on whether this fixed layer is colorless or colored, it may be greatly related to the ground color of the hard substrate 1 and the color of the sand grains. This needs to be taken into consideration especially when the sand grains, etc. are sparsely distributed, that is, when the sand grains, etc. do not adhere to each other but are dispersed with some gaps. The fixing layer 5 is for temporarily fixing sand grains and the like 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 synthetic resin paints include phenolic resin, polyurethane resin, phthalic acid resin, polyester resin, vinyl acetate, alkyd resin, vinyl chloride resin, silicone resin,
It is a paint whose main component is other well-known resins. 6
is sand grains such as silica sand, shirasu, crushed stone (marble, Oya stone) rock powder, perlite, talc, bentonite, diatomaceous earth, vermiculite and other well-known stones, or organic or inorganic coloring agents attached to these materials. Also includes colored sand grains that have been deposited, coated, or impregnated. Reference numeral 7 refers to reflective particles, which are particles that are large and highly reflective when exposed to light, such as glass particles, aluminum pieces, or other metal pieces with particularly high reflectance, or sand grains 6 with highly reflective substances or fluorescent substances attached. It consists of so-called granules that have been adhered or coated. Further, the size and shape of the sand grains 6 and the reflective grains 7 do not need to be particularly limited, but since h of the above-mentioned concave pattern surface is usually about 0.1 to 3 mm, the sizes should be approximately corresponding to this. For example, from a few mm in diameter
It is up to about 300 meters. Note that when h=0.7mm, 28 to 32 meshes are often used. Furthermore, when the distribution state of the sand grains 6 and the reflection grains 7 is enlarged, it is as shown in FIGS. 2a and 2b. That is, FIG. 2a is a vertical cross-sectional view showing an extracted and enlarged portion of the decorative surface 2, and shows a concave pattern surface in which the sand grains 6 and the reflective grains 7 do not come into contact with each other, and are so-called sparsely dispersed. FIG. 2b is an enlarged sectional view showing a dispersed state in which these grains are in close contact with each other.
As is clear from the figure, the sand grains 6 and the reflective grains 7 are distributed with only their lower portions fixed to the fixed layer 5, and therefore exhibit complex optical effects. Reference numeral 8 denotes a transparent resin layer, which is used to coat the concave pattern surface 3 and the convex pattern surface 4 after fixing the lower parts of the sand grains 6 and reflective grains 7 with a fixing layer 5, as shown in FIG. It is coated in a film form. The main functions of this transparent resin layer 8 are (1) to prevent deterioration of the color and reflectance of the sand grains 6 and reflective grains 7, (2) to prevent these sand grains from falling off, and (3) to improve the weather resistance of the decorative surface. 2. To faithfully express the color of sand grains, reflective grains, and the color of the base of the hard substrate on the decorative surface. 1. To improve the refractive index of reflective grains and colored grains using a transparent resin coating. secondary effects, such as obtaining differences in reflectance depending on the line of sight. As materials for forming the transparent resin layer, acrylic resin, acrylic resin and alkyd resin, acrylic resin and melamine resin, and other well-known transparent paints are used. Note that the coating amount of the transparent resin layer is arbitrary depending on the purpose. Furthermore, the drying method is either natural drying or forced drying (baking). In addition, in FIG. 3, the fixed layer 5 and the transparent resin layer 8
Although clearly divided and drawn, the boundary may become a mixed layer depending on the state of the fixed layer 5.

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 be formed into various bonding structures as shown in FIG. 4 or not shown. In FIG. 4, 9 is a side wall, 10 is an insertion edge, 11 is an insertion groove, and 12 is a protruding edge. By connecting the male and female parts, a wall, etc. can be easily formed. Furthermore, the back surface of the decorative surface 2 can be filled with a cross-sectional material 13 such as polyurethane foam. It is also possible to use a translucent paint instead of the transparent resin layer.

As mentioned above, the construction panel according to the present invention has excellent features in the following points. In other words, because the sand grains and reflective grains are mixed and distributed over the concave and convex patterned surface, the specular reflection (gloss) on the convex patterned surface and the diffused reflection (so-called gloss) on the concave patterned surface are different. Because there are reflective particles that appear randomly and reflect accents in the diffused reflection, it is possible to significantly enhance the three-dimensional effect and obtain a decorative surface with a new reflective surface structure. Since a small undulating surface is formed by distributing small particles such as sand grains on the concave pattern surface, a diffused reflection surface can be easily formed. grains of sand,
The essence (appearance, texture) of the hard base material, which allows the characteristics of reflective grains to be fully exhibited on the decorative surface, is almost completely erased, and a rare patterned surface is presented. It is possible to prevent deterioration of sand grains, reflective grains, and the performance of the base color of the decorative surface, such as color and reflectance.
