Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention comprises a thin metal plate having an uneven pattern on the decorative surface, or a slate plate, a calcium carbonate plate, asbestos cement and pearlite particles, an ALC plate, and the like. The present invention relates to a method for forming a decorative surface that allows each decorative surface of a panel having an uneven pattern such as a stucco pattern to have a more three-dimensional appearance.

Generally, the exterior surface made of a thin metal plate, for example, the interior, exterior wall, roof material, roof deck, parapet, and other decorative surfaces are flat surfaces, lysine surfaces, embossed patterns, and ceramic panel decorative surfaces are flat surfaces. The exterior has a stucco pattern or a mastic pattern. Further, the exterior material using a thin metal plate is merely artificial aesthetic, and the embossed pattern can be seen only as thin unevenness, which has a defect that the three-dimensional effect is poor. Further, the ceramic panel has a more natural feeling than the thin metal plate, but lacks a deep three-dimensional effect and has a disadvantage that it is not easy to form an uneven pattern.

In order to eliminate such defects, the present invention applies a three-dimensional sensitizer with directionality to at least a pretreatment coating, an exterior material having a decorative coating, or a decorative surface of a ceramic panel, and has a convex pattern. The present invention proposes a method for forming a decorative surface in which the above-mentioned promoter is wiped off and exposed so that the decorative surface is visually illusion of a deeper textured surface and also gives a natural feeling.

〔Example〕

Hereinafter, the method for forming a decorative surface according to the present invention will be described in detail with reference to the drawings. FIGS. 1 (a) and 1 (b) are explanatory views showing an example of an exterior material extracted by the method for forming a decorative surface according to the present invention. FIG. 1 (a) is an exterior material made of a thin metal plate. If 1, a case of (b) drawing the outer package 1 made of ceramic-based '. More specifically, the thin metal plate 2 is a surface-treated steel plate, galfan, galvalume steel plate,
Stainless steel plate, aluminum plate, copper plate, ceramic board 2'is gypsum board, slate, calcium carbonate plate, calcium silicate plate, cement and calcium and aluminate, sulphate and hydrate as main raw materials, pulp, glass Plates made of materials such as Seny and perlite mixed, asbestos cement calcium silicate board, foamed concrete board, cement board containing high-strength alkali glass fiber in cement, and asbestos cement mixed with pulp and perlite. Is. In addition, the exterior material 1 ,
Uneven pattern 5 made of Toka凹模like 3 and the convex pattern 4 on the surface of the 1 '
Is to have. A masking coat 6 is applied by a roll coater 7 on the top surface 4a of the convex pattern 4 of the exterior material 1 as shown in FIG. Masking coat 6
Is capable of temporarily covering the color and pattern on the top surface portion 4a, and finally wiping it off to expose the top surface portion 4a directly to the decorative surface, with a viscosity that does not flow into other than the top surface portion 4a, and can be wiped off. It is made of a material that does not come out and does not adversely affect the cosmetic surface. Specific examples are paints,
It consists of one type such as PVA and water (shimesu only). Reference numeral 8 denotes a three-dimensional accelerating agent (hereinafter, simply referred to as an accelerating agent), and as shown in FIGS. It is distributed on one or more parts of the bottom surface part 3a of the other concave pattern 3 described above. More specifically, the facilitating agent 8 has a visual element on the makeup surface, that is, in addition to a mechanical uneven pattern, a shadow function is added to the uneven pattern 5 to provide a deeper and richer three-dimensional appearance. It is for. The material is at least slightly different from the color and density of the decorative surface, and is made of one kind such as paint and asphalt. In addition, as a coating method, the spray gun 9 is applied so as to collide with the traveling direction of the exterior materials 1 and 1 ′ at an angle θ.
3 is installed as shown in FIG. 3A, or the promoter 8 is applied by a roll coater 10 as shown in FIG. 3B or a curtain flow coater (not shown).
In this case, the moving speed of the exterior material 1 is such a speed that the promoter 8 applied by the roll coater 10 or the curtain flow coater does not apply to at least a part of the convex side surface 4b. Reference numeral 11 is a wiping roller for wiping off the uncured masking coat 6 and the promoter 8 existing on the top surface 4a as shown in FIG. The structure is composed of a wiping roller 11, a roller 13 for storing the solvent 12, and a doctor knife 14, and at least one stage and, if necessary, a plurality of stages (not shown) are installed in parallel. 15
Is a heater for drying or baking the promoter 8 present in the uneven pattern 5 of the exterior material 1 as shown in FIG. 5. Specific examples thereof include a hot air method, an open flame method, and a hot wire method. It is either.

Next, an example of the method for forming a decorative surface according to the present invention will be described. Now, the exterior material 1 is wound in a coil shape.
It is assumed that a 0.27 mm-thick color steel plate (a white alkyd resin-baked plate material) has an uneven pattern 5 having a depth of 0.9 mm formed on its surface by embossing. Therefore, the second
As shown in the figure, the exterior material 1 is conveyed in the direction of arrow A at a speed of 60 m / min through a conveyor, and a color close to white (masking coat paint 6) is applied to the top surface 4a thereof by a roll coater 7. . Next, as shown in FIG. 3 (a), the spray gun 9 is used to move the promoter 8 (asphalt) to the decorative surface 5 moving in the direction of arrow A at the same speed as above, particularly the uneven pattern 5 at an angle θ = 45 °. To spray. In this case, promoter 8
Are distributed on the surface of the top surface portion 4a and the side surface portion 4b orthogonal to the spray direction of the spray gun 9, and on the bottom surface 3a. In other words,
A portion of the side surface portion 4b that is not orthogonal to the spray direction is in a state in which the promoter 8 does not exist at all, and other portions exist in some degree depending on the angle. Next, as shown in FIG. 4, the masking coat 6 and the promoter 8 existing on the top surface 4a are wiped off via the wiping roller 11, and are fed to the step of drying the exterior material 1 as shown in FIG. . In Fig. 5, a promoter 8
Is cured and delivered as a product. Of course, when the promoter 8 is a synthetic resin type paint, it is carried out by one of curing, drying and baking.

[Other Examples]

What has been described above is only one example of the method for forming a decorative surface according to the present invention, and as shown in FIGS. 6 (a) and 6 (b),
It can be formed on the exterior material 1 having the uneven pattern 5 having a three-stage structure. Further, the hardness of rubber, sponge, etc. of the roller coater 7 and the wiping toler 11 can be selected according to the purpose. For example, in FIG. 6 (a), the top surface portion lower than the top surface portion 4a '
It can also be formed so that the promoter 8 applied to 4a is not wiped off.

〔The invention's effect〕

As described above, according to the method for forming a decorative surface according to the present invention,
It is extremely easy to form a visual shadow on a concavo-convex pattern with directionality, and as a result, there is a feature that a deep and rich three-dimensional appearance is obtained. Further, since the promoter can be sprayed at an arbitrary angle, there is a feature that a makeup surface having various shades can be easily formed.
