Abstract

PROBLEM TO BE SOLVED: To solve problems in conventional building plates such as a flat plate with a flat decorative face, a three-dimensional pattern plate with a three- dimensional pattern formed by embossing or a mold, a two-color coated plate using different colors between the projecting parts and recessed parts of the three-dimensional pattern plate, and the like which are used as interior and exterior materials, but the three-dimensional pattern of the mere three- dimensional pattern plate becomes unrecognizable when viewed at a distance, and the two-color coated plate gives the monotonous impression of only the color difference between the projecting parts and the recessed parts only to emphasize the repeated monotonous rugged pattern which is far from acquiring a three-dimensional effect particularly when viewed at a distance. SOLUTION: The rugged pattern is formed at a part of a decorative face of this building plate, and a shrinkage paint with a small quantity of pigment component (with a large quantity of resin component) is applied to the decorative face. The viscosity, fluidity, surface tension, and the like of the shrinkage paint are used to obtain design in harmony with the height difference of the rugged pattern.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an architectural plate having an uneven pattern used for the interior and exterior of a building, which is painted so as to emphasize the unevenness to enhance the design.

[0002]

2. Description of the Related Art A conventional architectural board is a flat board having a flat decorative surface, a three-dimensional pattern board in which a three-dimensional pattern is formed by embossing or a mold, and a two-color pattern in which the color is changed between a convex portion and a concave portion of the three-dimensional pattern plate. There are painted boards, etc., which are used as interior and exterior materials.

[0003]

However, a mere three-dimensional pattern plate makes it difficult to understand a three-dimensional pattern when viewed a little away, and a two-color painted plate is monotonous, in which only the color differs between the convex portions and the concave portions. It only emphasizes the monotonous pattern of repetition, and does not provide a three-dimensional effect especially when viewed from a distance.

[0004]

According to the present invention, an irregular pattern is formed on a part of a decorative surface of an architectural plate, and the decorative surface is coated with a fine paint containing a small amount of a pigment component (a large amount of a resin component). By utilizing the viscosity, fluidity, surface tension and the like of the paint, it is possible to obtain a design property along the height difference of the uneven pattern.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The paint used in the present invention is a dirt paint, and the pigment component is 1 to 30% by weight of the total paint, and the solvent component is 10 to 30% by weight. That is,
The pigment component is smaller than that of a general lacquer paint.

By reducing the amount of the pigment component and increasing the amount of the resin component of the paint, the fluidity of the paint becomes higher, so that the paint becomes easier to flow in accordance with the level of the uneven pattern. Since the hiding power is lower, a difference in gloss due to the shading of the color and the fine pattern occurs according to the film thickness.

That is, in the uneven pattern, since the coating thickness gradually increases from the upper side to the lower side of the inclined surface, the color tone becomes darker in accordance with the thickness, and the smaller the coating thickness, the smaller the shrink pattern or The glossiness is close to the original glossiness of the paint itself, and the thicker the coating film, the larger the dust pattern becomes and the lower the glossiness becomes.

Further, the design property of the present invention not only depends on the fluidity of the coating material, but also can change the viscosity and surface tension of the coating to give a difference in the three-dimensional appearance of the coating film itself.

In general, even when an uneven pattern is formed on an architectural plate coated with a dirt paint, a certain three-dimensional effect can be obtained, but a monotonous feeling cannot be denied. By changing the coating thickness in accordance with the height difference, the excellent coating can exhibit excellent design without monotonous feeling.

[0010] The architectural plate used in the present invention may be a metal plate or an inorganic plate, and is not particularly limited. The plate may be a base plate or a substrate which has been subjected to ground treatment or painting. However, a material that hinders the fluidity of the dirt paint is not preferred.

The uneven pattern is not particularly limited. The number of flat portions may be large or small. However, the uneven pattern may be determined in consideration of a change in the thickness of the coating film due to the fluidity of the paint. Good.

The coating method used in the present invention includes a curtain flow coater, a spray, a roll coater, etc., but is not particularly limited, and may be selected in consideration of the viscosity of the coating material and the like. Further, by applying air blow or vibration immediately after coating, the fluidity can be further promoted, or a design that cannot be obtained with the above-described coating machine alone can be obtained.

An embodiment according to the present invention will be described below, but the present invention is not limited thereto.

(Example) On a color steel sheet having an uneven pattern as shown in FIG. 1, a paint was applied using a roll coater. The paint used was 51% by weight of the polyester resin, 20% by weight of the pigment component, 10% by weight of the additive, and 19% by weight of the solvent. FIG. 2 shows a part of a section of a building plate obtained by flowing and drying the dirt paint. 1 is a color steel plate and 11 is a coating film. The painted steel plate gradually becomes darker in color from the upper part to the lower part, and similarly, a difference in gloss due to the fine pattern is generated, and even when viewed from a distance, the three-dimensional pattern is formed along the height difference of the uneven pattern. The pattern was clear and the design was excellent.

[0015]

According to the architectural plate of the present invention, the flowability of the paint is increased by reducing the pigment component of the paint, and the thickness of the coating gradually increases from the upper part to the lower part of the uneven pattern. Therefore, the color gradually becomes darker in accordance with it, and furthermore, the gloss becomes low due to the fine pattern, and the pattern is clear along the height difference of the concavo-convex pattern, and the design is excellent.
