[Prior art]

 BACKGROUND ART Conventionally, as one of the means for decorating the outer surface of buildings, structures, walls such as partition walls, columns, etc., various types of paint have been applied to the surface of factories or factory sites. . For on-site painting, it is difficult to ensure performance depending on weather conditions, work conditions, and processes, and the finish depends largely on the skill of the worker. For these reasons, the proportion of painting by factory line has been increasing in recent years. However, for factory coating, a method that allows thick coating is proposed by partially devising the coating in Japanese Patent Application No. 4-100259, but it is still a general-purpose thin finish coating material. Only the top coat is painted. In addition, it has become popular to attach a stone-faced decorative sheet to the above-mentioned wall surface and the like on site.

[Problems to be solved by the invention]

 Among various coating materials, when it is desired to obtain a stone-finished surface, for example, a coating material called a skin-based coating material containing a plurality of natural stones or colored fine aggregates in a synthetic resin emulsion is used. By using wood or a few materials, the finish of the pattern without unevenness and regularity was obtained by relying solely on the skill of the painter. In the field painting, the work was complicated, and the unpainted part had to be cured, and it took daily time to obtain a dry coating film, and it was necessary to avoid rainfall. Also, there is no problem when finishing the entire surface with the same coating material, but it was very difficult to change the color depending on the surface or building material panel. Similarly, in building material panels, flat surfaces and corner members are manufactured separately, which makes it difficult to manufacture the same lot in the same lot, especially when using a skin-based coating material for various patterns. It was difficult to do. Even for painted building material panels, when multiple skin-based coating materials are used, differences occur in the color of the entire coating film and the size of the pattern grains between the panels, and the color changes when the panels are lined up. It was sometimes reflected as a difference. The products on the market have a large size per building material panel of 1.5 x 10 (shaku) or 3 x 6 (shaku), and the difference in color when the panels are arranged vertically and horizontally is easily noticeable. It was

On the other hand, although the method of sticking a stone-skin-like decorative sheet on site reduces the work on site and stabilizes the performance and quality of the sheet, it nevertheless adjusts the base for applying the decorative sheet. It took a lot of time to work, allocate decorative sheets, and attach them. There is also a demand for simpler construction by integrating the base plate-like siding and the decorative layer in the process of prefabricating.In this way, the wall formation and finishing can be done in one step. I had expectations.

In this invention, by providing a relatively small-sized painted decorative board having a coating film of a skin-based coating material having a thick feeling on the surface of a member appearing on the surface of a building material used for walls, columns, etc. , Even if there is a slight color difference, it is easy to devise the arrangement order when attaching the porcelain tiles.

[Means for Solving the Problems]

 In order to solve the above problems, in the invention of claim 1, ceramic siding having a particle size of 0.01 to 4.0 mm and ceramic crushed particles having a particle size of 0.01 to 4.0 mm are provided for ceramic siding having a length of 30 to 60 cm and a width of 45 to 90 cm. , A plurality of different colors of fine aggregates selected from ceramic grains, pre-colored fine aggregates or natural stones, and a decorative material layer spread in a synthetic resin in a speckled pattern are laminated. Similarly, according to the second aspect of the invention, for ceramic siding having a length of 30 to 60 cm and a width of 45 to 90 cm, crushed ceramic particles, glass particles, ceramic particles having a particle diameter of 0.01 to 4.0 mm, previously colored. It is made by laminating a decorative material layer that has a fine sand aggregate or fine stone selected from natural stones in multiple colors and has a sandstone split skin pattern spread on a synthetic resin. The invention of claim 3 is characterized in that a clear paint layer is further provided on the surface of the decorative material layer of claim 1 or 2. The invention of claim 4 is characterized in that the ceramic siding in the invention of claim 1, claim 2 or claim 3 is a plate processed by four-way consensus processing.

First, ceramic siding, which is a base material for coated decorative boards, is exemplified by silica board, pulp cement board, gypsum slag board, asbestos perlite board, wood chip cement board, and cement extrusion molding. There are boards, ALC plates, various siding boards, etc. The size of this siding is set to 30 to 60 cm in length and 45 to 90 cm in width so that the efficiency of the processing is good and the size can be rearranged even when the color and pattern of the decorative material are different. This is because

The decorative material layer is a portion for making a design on the surface of the building material of the present invention. Decorative materials are natural stones and crushed stones, finely colored aggregates pre-colored, crushed colored plastic particles or fine particles of colored plastics, glass particles, ceramic particles, and synthetic resin emulsions, solvent type The main component is a binder selected from synthetic resin, water-soluble resin, hot-melt resin, and water-soluble silicate salt. In the case of a granite pattern, a plurality of the compositions containing the aggregate and the binder as the main components are used as a paint or a molded product. In the case of paint, spray, apply or drop onto siding and dry. In the case of spraying, it is easy to make a spot pattern using a multi-head spray gun. In the case of a sandstone pattern, the composition containing the aggregate and the binder as the main components is used as a paint or a molded product. In the case of paints or molded products, it is necessary to apply a split skin pattern on the surface, brush it, and mold it so that it looks like a sandstone.

The particle size of the aggregate to be blended in the decorative material is 0.01 to 4.0 mm because the color expressed by each paint is less than 0.01 mm when forming a spot pattern. May become a flat plate, or the part where the paints are mixed may become a mixed color, resulting in a muddy color. On the other hand, when using aggregates exceeding 4.0 mm, the surface becomes rugged, and gaps are created between the aggregates, and the gaps are filled with a binder, which is unnatural compared to natural stone. In some cases, the boundary between multiple paints is too clearly visible.

The clear paint layer that may be formed on the surface of the decorative material layer is used for improving the weather resistance of the decorative material layer, protecting it, or imparting gloss. Acrylic resin, acrylic urethane resin, acrylic silicone resin, and fluororesin are examples of the main resins that make up the clear paint.

The four-sided consensus processing in the ceramic siding is to provide male and female fruits on two adjacent two sides of the four sides of the rectangular siding. When a painted decorative board that has undergone a four-sided joint process is to be constructed at a construction site, it is fixed to the foundation pillar or furring strip so that the male and female fruits form a pair.

The decorative coating plate of the present invention will be described with reference to the drawings. FIG. 1 is an external perspective view of the embodiment. In the figure, reference numeral 1 is a coated decorative plate, and reference numeral 2 is a male fruit. FIG. 2 shows a cross-sectional view taken along the line AA of FIG. 1, in which reference numeral 3 indicates a female seed, reference numeral 4 indicates a base material, and reference numeral 5 indicates a decorative material layer. FIG. 3 shows a sectional view taken along the line BB of FIG.

【Example】

 In Example 1, for a ceramic siding processed by four-way consensus, an effective dimension of 30 cm × 60 cm × 23 mm, a finish coating material “Chinaton CT-24” manufactured by Kikusui Chemical Co., Ltd., which is a natural stone finish Painted with three spray guns. Before coating, curing was carried out to prevent the coating material from adhering to the male part, the mouth and the edge of the tree. The above-mentioned CT-24 is a coating material composed of three colors of white, light green, and light black. After coating, rollers were used to hold the convex and concave portions, and after drying, sanding was performed to further equalize the thickness. After this, clear paint of acrylic silicone resin was applied. The obtained decorative coating plate was fixed to the outer wall of the detached house by fitting it with metal to finish the outer wall. Although some colors were emphasized in light green or light black on the decorative coated board, the degree of emphasis was fixed in an inconspicuous order, resulting in no problem.

In Example 2, a finish coating material “Natural Tone NW-1”, which is a natural stone-like finish, was applied to the ceramic siding of 45 cm × 45 cm × 24 mm in effective dimensions, which had been subjected to a four-sided consensus process, and Kikusui Chemical Co., Ltd. ) Was painted with a double-headed gun. Also in this case, before coating, curing was performed so that the coating did not adhere to the male part, the wood mouth and the edge of the tree. The NW-1 is a coating material composed of two colors, light gray and dark gray. Before curing after application, it was passed under the brush roll so that a brush-drawn pattern was formed on the surface. After the finish coating material was dried and cured, a clear paint of urethane resin was applied. The obtained decorative coated board was fixed to the outer wall of a two-story apartment house with metal fittings to finish the outer wall. Due to the small panel size, the processability was good, and the panel loss was small, resulting in a good finish.

In Example 3, a finishing coating material “Sandstone SD-1”, which is a sandstone-like finish, is applied to a ceramic siding having an effective size of 45 cm × 45 cm × 24 mm that has been subjected to a four-sided consensus processing. Co., Ltd. was applied with a knife coater. Also in this case, before coating, curing was performed so that the coating did not adhere to the male part, the wood mouth and the edge of the tree. Before being cured after application, it was passed under a brush roll so that a brushed pattern was formed on the surface. After the finish coating material was dried and cured, a urethane resin clear coating was applied. The obtained decorative coated board was fixed to the outer wall of a two-story apartment house with metal fittings and fixed to finish the outer wall. The obtained outer wall surface was designed in such a way that each panel was independent, and the finish was even closer to that of a real stone.
