Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a building panel, particularly a construction panel that exhibits a special appearance as a surface design through a material that is impermeable and has good thermal conductivity, such as a metal plate.

More specifically, the present invention relates to the production of a construction panel in which a flat surface of convex portions and a concave surface filled with sand grains or the like are densely filled with a minimum number of man-hours on a decorative surface having an arbitrary uneven pattern. In a construction method that is generally referred to as a conventional construction method, for example, a mortar ricin wall is commonly used as the outer wall.

However, recently, dry construction methods have become widespread due to construction schedule constraints and cracks in the mortar walls themselves. One such product is the so-called metal siding, which is formed from a metal plate and filled with a core material and a heat insulating material. With respect to the surface, that is, the decorative surface, various measures have been taken to improve the color, brightness, three-dimensional effect, etc. along with advances in paints and the like. For example, products that resemble pseudo-mortar walls have appeared, with ricin coating applied to decorative metal surfaces. However, due to the technical difficulty of uniformly distributing sand grains on a flat surface, the design effect was extremely low. In order to eliminate such defects, the present invention selects a metal plate as the base material, and utilizes its excellent plasticity to randomly form irregularities in an arbitrary pattern. Only the concave portions of the surface are filled with sand grains having a resin coating at a high density, and at least a portion of this coating dissolves to function as an adhesive and paint layer, and the surface is flat and reflective. The present invention provides a method for manufacturing an architectural panel having a sand decorative surface that exhibits a new decorative surface due to the at random distribution of the diffused reflection surface of the surface and the concave portions having minute undulations.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a construction panel having a sand decorative surface according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing a portion of a building panel obtained by the present invention on a scale of 1:1. In the figure, 1 is a construction panel with concave parts 2 and convex parts 3 arranged randomly (
distribution) and a decorative surface 5 in which the concave portions 2 are densely filled with sand grains 4 having a resin-coated film. To explain in more detail, the shape of the concavo-convex portion is an arbitrary pattern, for example, as shown in Fig. 2 a, b, and c.
The shapes are as shown in figures a, b and c. The sand grains 4 are composed of aggregates 4a and coatings 4b, and the aggregates 4 include silica sand, sand, rock grains, ceramic grains, glass grains, mineral grains (kaolin, talc), shirasu, shirasu balloons, pearlite grains, etc. Use one type or a mixture of two or more types. It is preferable that the grain size does not protrude beyond the depth of the concave portion at most, and for example, a filling structure as shown in FIGS. 4a, b, and c is possible. That is, the concave portion can be filled not only with one layer but also with several layers. Also, the external shape of the grains is not necessarily limited to spherical, but similar external shapes, triangular, scaly, etc.
The coating 4b, which may be a mixture of grains of any shape such as square or oval, or a single grain, is made of acrylic resin, alkyd resin, melamine resin, ABS resin, phthalkyd resin, polyvinyl chloride resin, polyester resin, etc., and is coated on the aggregate. The state of the film is that it is not completely polymerized, the so-called surface is in an apparently hardened state, or that it is not hardened or hardened in the air drying or competitive type. In other words, when it is irradiated or immersed in a hot solvent, water, etc., at least a portion of the coating dissolves and then hardens. Next, it is assumed that an embodiment of the method for manufacturing a building panel having a sand decorative surface according to the present invention will be described in detail.

Although not shown, if a panel such as a colored iron plate having an uneven part of about 8 feet is continuously conveyed in a certain direction via a conveying means such as a roller or a V-belt flat belt, initially 32 to 28 mesh diluted with 20 micron triol in silica sand 4a,
Sand grains 4 having a film 4b coated with an acrylic resin set to centipoise are uniformly scattered on the uneven surface. This process corresponds to the mouth shown in FIG. Next, the sand grains 4 existing on the convex portion 3 are removed. This process is shown in FIG. 5c and FIG. 6c. So next 120
℃ is applied with a heater or the like (as shown in FIG. 5 D) to melt at least a portion of the coating 4b, and also to bond and integrate the sand grains together, as well as to bond and integrate the coating on the color coat of the colored iron plate. Next, this is transferred to the next step, the so-called leaving step shown by E in FIG.

The results are shown in Figure 6d. What has been described above is only one embodiment of the present invention, in which powdered resin is adhered to aggregates, the resin is melted by applying heat or irradiation with a solvent, and then a polymerization reaction is caused. A similar structure can also be obtained by forming a normal coating film as a result.

It is also possible to form a finishing coat again on such a decorative surface. As described above, according to the method for manufacturing a construction panel having a sand decorative surface according to the present invention, silica sand or the like is sprinkled,
The sanitary conditions of the working environment are very good, since the excess of it is removed and only heat is added to it.

In addition, the work efficiency is very high, unlike when using a paint film. Furthermore, since the particles themselves have a coating, there is no insufficient adhesion or falling off, and the aggregate and lateral membrane coatings are exposed at random, giving the particles a unique appearance.
