Abstract

PROBLEM TO BE SOLVED: To accentuate a embossed pattern by coating the surface of a base material, that is provided with an embossed pattern, with a coating material of a predominant color and thereafter subjecting only the rising parts of the embossed pattern of the surface to spray coating with another coating material of another color that belongs to the same family as that of the predominant color and has lower brightness as compared with the predominant color, through spraying the coating material of the color having lower brightness on the surface of the material in one oblique direction to the surface. SOLUTION: In this method, a panel which is e.g. a ceramic based exterior panel and provided with a embossed pattern formed in its surface by press forming or the like, is firstly coated with a coating material of a dominant color 3. At this time, the whole surface of a base material 1 is uniformly coated by roll coating or spray coating, however, when the difference in height between the projecting parts and the recessed parts is small, the surface is thinly coated so as not to bury the recessed and projecting parts with the resulting coating film. Then, another coating material of another color which is used as a silhouette 4 of the dominant color 3 of the surface of the base material 1, and also, belongs to the same family as that of the dominant color 3, and further, has lower brightness as compared with the dominant color 3, is sprayed on the surface of the base material 1 in one oblique direction to the surface so that only the rising parts of the embossed pattern of the surface is preferentially coated. Thus, shade and shadow of the embossed pattern become clear to increase the stereoscopic effect of the pattern and to accentuate the pattern.

2. Description of the Related Art Conventionally, in ceramic exterior panels and the like, those having a surface provided with an uneven pattern by press molding or the like have been generally used. In such an exterior panel, a finished product is obtained by applying a desired color to the surface of a base material that has been subjected to curing and curing by applying an uneven pattern by press molding or the like.

[0003]

However, in the exterior panel having the surface coated with the uneven pattern as described above, depending on the painted color, the depth of the unevenness, the shape of the unevenness, the size, etc., When viewed from a slightly distant position, the concavo-convex pattern became inconspicuous, and in some cases it appeared to be flat.

The present invention has been made in view of the above circumstances, and provides a coating method for an uneven surface which can enhance the uneven pattern when coating the surface of a base material provided with the uneven pattern. Is.

[0005]

According to a first aspect of the present invention, there is provided a method for coating an uneven surface, wherein a base color is applied to a surface of a base material having an uneven pattern, and then a similar color having a lower lightness than the base color is applied. Is inclined with respect to the surface of the base material and spray-coated from one direction, and the similar color is applied only to the rising portion of the uneven pattern.

In this uneven surface coating method, a similar color having a lower lightness than the base color applied to the base material is tilted with respect to the surface of the base material and spray-coated from one direction to form an uneven pattern. Since the above-mentioned similar color is applied only to the portion, the concave and convex pattern has a visually distinct shadow, which enhances the three-dimensional effect. Therefore, the uneven pattern can be emphasized.

According to a second aspect of the present invention, there is provided an uneven surface coating method, wherein the base material is a ceramic exterior panel.

According to this method of coating the uneven surface, it is possible to obtain a ceramic exterior panel in which the uneven pattern is emphasized.

According to a third aspect of the present invention, there is provided an uneven surface coating method, wherein the base material is an exterior projecting corner member.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described based on a method for coating an uneven surface according to an embodiment.

1A, 1B, and 1C are cross-sectional views of a base material showing a procedure of a method for coating an uneven surface according to an embodiment of the present invention.

In this embodiment, first, as shown in FIGS. 1A and 1B, a base color is applied over the entire surface of the base material 1 to which the uneven pattern is applied. In the figure, 2 indicates a convex portion and 3 indicates a base color layer.

As the base material 1, a ceramic-based inorganic cured plate is used, and the unevenness pattern on the surface is not particularly limited, and the arrangement, shape and size of the unevenness are geometric. May be irregular, and the height (depth) of the unevenness is not limited, but the present invention capable of emphasizing the uneven pattern is more effective when the height difference is small. Can be said.

The method of applying the basic color is not particularly limited, and known methods such as roll, spray, curtain and brush coating can be applied, but the entire surface is uniformly coated. Preferably, when the unevenness of the unevenness of the unevenness pattern is small, it is preferable to apply a thin coating so that the unevenness is not filled with the coating film.

The basic color is not particularly limited, and any desired color can be selected. However, if the color has a large lightness, the present invention is particularly preferable because the lightness and darkness can be clearly defined.

Further, as shown in FIG. 1C, a color suitable for the silhouette of the basic color of the surface of the base material 1, that is, a similar color having a lightness lower than that of the basic color (hereinafter, such a color is referred to as a silhouette). The coating material (referred to as color) is sprayed from one direction to the surface of the base material 1 so that the coating material is sprayed so as to be attached only to the rising portions of the unevenness. At this time, the inclination angle to be sprayed is not particularly limited, but when the angle approaches 90 degrees, it is not preferable because the silhouette color tends to adhere to portions other than the rising of the unevenness, and when the angle is too small. It is not preferable because it is reflected on the surface of the base material 1 and is less likely to adhere to the rise of irregularities. The optimum angle of the sprayed angle depends on the pattern of the uneven pattern and the amount of the sprayed paint, so it is better to consider the balance with these angles and set it to an appropriate angle.
It is 0 to 60 °. In the figure, 4 indicates a silhouette color layer.

The spraying direction on the base material 1 is preferably from the lower side when, for example, the base material 1 is an exterior panel or exterior exterior corner member and the vertical direction is fixed.

In the method of coating the uneven surface, since the surface of the base material 1 is coated as described above, the uneven pattern is a pattern in which the shade is visually clear, and the three-dimensional effect is enhanced, and the uneven pattern is emphasized. It becomes a thing.

Therefore, when the exterior panel is used as the base material 1, the exterior wall surface in which the uneven pattern is emphasized can be formed by using the exterior panel, and at the same time, the exterior corner member is used as the base material. When the same coating as the exterior panel is used as 1 in combination, the uneven pattern can be emphasized also in the outer corner of the outer wall.

[0021]

According to the method for coating an uneven surface according to claim 1, spray coating from one direction by inclining a similar color having a lower lightness than the base color applied to the base material with respect to the surface of the base material. Then, since the similar color is applied only to the rising portion of the uneven pattern, the uneven pattern is a pattern in which the shade is visually clear, and the three-dimensional effect is increased. Therefore, the uneven pattern can be emphasized.

According to the second aspect of the present invention, it is possible to obtain a ceramic exterior panel in which the uneven pattern is emphasized.

According to the third aspect of the present invention, it is possible to obtain the exterior protruding corner member in which the uneven pattern is emphasized.
