Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial application >> The present invention relates to a decorative method for a surface of a building wall material for applying a makeup with a metal spray coating.

<< Conventional Technology >> There have conventionally been various exterior or interior finishing methods for building wall materials, but in recent years, as disclosed in, for example, JP-A-61-117264, metal spraying has been performed on the surface of building wall materials. There is a method of forming a film to have a metallic glossy surface.

In this way, by making the metal glossy surface by the metal spray coating, it is possible to give a dignified and beautiful makeup.

<< Problems to be Solved by the Invention >> However, in such a conventional method of applying a metal spray coating to a building wall material, since the metal spray coating is formed integrally with the building wall material, It becomes extremely difficult to make up the makeup when the color tone of the metal spray coating changes or the gloss deteriorates.

That is, in such a makeup repair, the old metal spray coating is uniformly peeled over the entirety, and the metal spray coating is formed again after the peeling, but the metal spray coating integrated with the building wall material is peeled off. Is extremely troublesome, and cannot be practically used.

In addition, in such a makeup method using a metal spray coating,
As disclosed in JP-A-56-161150, there is a method in which a porous metal coating layer and a densified porous metal layer are formed into a multi-layer, and even in this method, the porous metal coating layer and the dense In this case, it is difficult to separate the metal layer as in the case of the above-described conventional technique, and the makeup is significantly complicated.

Then, in view of such a conventional problem, an object of the present invention is to provide a decorative method of a building wall material that can easily remake a metal sprayed coating.

<< Means for Solving the Problems >> In order to achieve this object, the present invention provides a plurality of metal spray coatings on the surface of a building wall material, a buffer material such as a heat-resistant resin interposed between the coatings, and a layer of each metal coating. It was formed into a multi-layer so as to be peelable, and the building wall material was once decorated with the outer layer of the metal spray coating of the multilayer, and after a lapse of time, the outer layer of the metal spray coating was peeled off to expose the lower layer.

It is preferable that a buffer material such as a heat-resistant resin is interposed between the multiple metal spray coatings.

<< Operation >> In the makeup method of the building wall material of the present invention with the above configuration, since the metal spray coating is formed in multiple layers on the surface of the building wall material so that each layer can be peeled off, The outer layer can be easily peeled off.

And the outer layer deteriorates or after a certain period of time,
The outer layer is peeled off, exposing the lower layer. Then, since the newly exposed lower layer is not deteriorated because it has been covered with the outer layer up to that time, the lower layer becomes beautiful. Therefore, the makeup of the architectural wall material can be redressed by a simple operation of removing the outer layer.

And if the lower layer and the outer layer are made of the same material,
It can be returned to the same wall (atmosphere) as when it was built,
On the other hand, different materials can create a completely new atmosphere.

Further, by interposing a buffer material such as a heat-resistant resin between the multiple metal spray coatings, the peeling of the outer layer is further simplified.

<< Example >> Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 to FIG. 6 are explanatory diagrams sequentially showing one embodiment of a method for applying a makeup to a surface of a building wall material according to the present invention.
Numeral 10 is concrete for building wall materials.
As shown in the figure, a surface treatment is performed on the surface of the concrete 10.

In the base treatment, the heat-resistant mortar layer 12 is formed on the surface of the concrete 10.

Next, as shown in FIG.
Then, a coating of a buffer material 14 such as a heat-resistant resin is applied thereon, and then, as shown in FIG.
The first metal spray coating 18 is formed by using 16.

In the thermal spray gun 16, as is conventionally done, the thermal spraying is performed by heating powder particles of a metal to be melted by a flame and fixing it to the surface of the heat-resistant mortar layer 12.

Then, the first metal spray coating 18 thus formed is formed.
After further applying a buffer material 14 as shown in FIG. 4, a second metal spray coating 20 is similarly formed using a spray gun.
To form

Therefore, two layers of the metal spray coatings 18 and 20 are formed on the surface of the concrete 10, and the second layer as the outer layer is formed.
The surface of the concrete 10 is decorated by the metal spray coating 20 of.

FIG. 5 shows that when the second metal spray coating 20 on the surface of the concrete 10 is deteriorated with time, the surface is discolored or the metallic luster is lost, and the makeup is redressed. The second metal spray coating 20 is peeled off as described above. As a result, the first metal spray coating 18 is exposed, and thereafter, the metal spray coating 18 becomes an outer layer, and the redressing is completed.

In the decorative method of the surface of the architectural wall material according to the present embodiment as described above, the first and second metal spray coatings 18 and 20 are formed on the surface of the concrete 10, and the second metal spray layer serving as the outer layer is formed. Make the surface of concrete 10 once with 20.

Then, at the time of makeup repair, the second metal spray coating 20
Is done by polishing, stripping, etc.
Since the first metal spray coating 18 and the second metal spray coating 20 are laminated so as to be peelable from each other, the work of peeling the second metal spray coating 20 can be significantly simplified.

In this embodiment, the first and second metal spray coatings are particularly used.
Since the buffer material 14 is interposed between the 18, 18 and 20, the peeling of the second metal spray coating 20 is further facilitated.

Therefore, in the present embodiment, since the second metal spray coating 20 is easily peeled off, the work of redressing the surface of the architectural wall material is remarkably facilitated, and the work period and the cost required for the work can be reduced. Achieved.

In addition, since the makeup is simplified in this manner, the makeup can be easily repaired systematically for a fixed period of time, for example, every year, without being limited to the case of makeup repair due to aging deterioration. If the first and second metal spray coating layers 18 and 20 are formed, a finished surface having an unusual color tone or the like can be obtained, and a variety of makeup can be performed.

Furthermore, the metal spray coating laminated on the concrete 10 is:
It goes without saying that three or more layers may be used instead of two layers.

Furthermore, although the case where the buffer material 14 is interposed between the first and second metal spray coatings 18 and 20 is disclosed, the second metal spray coating 20 is easily peeled off by the buffer material 14, The cushioning member 14 is not always necessary, and even when the metal spray coatings 18 and 20 are directly sprayed with a certain time interval, the metal spray coatings 18 and 20 can be separated from each other.

Further, in the above-described embodiment in which the makeup is simply re-moulded by simply peeling the outer layer, the number of times of the makeup is limited to the number of layers of the metal spray coating formed in advance. Therefore, when the lowermost layer is exposed or before the outer layer is peeled off, a new metal spray coating may be applied so as to be peelable. By doing so, makeup can be redressed semipermanently.

<< Effects of the Invention >> As described above, in the decorative method of the surface of a building wall material according to the first aspect of the present invention, a metal sprayed coating can be peeled off in each layer on the surface of the building wall material to form a multilayer. Because it formed
It is possible to remarkably facilitate peeling of the metal spray coating as an outer layer at the time of redressing, and furthermore, it is possible to simplify the redressing, thereby shortening the operation period and cost required for this.

Also, by making makeup easy like this,
It is possible to increase the number of times of redressing, and it is possible to form a different metal spray coating every predetermined period, and to redress with a rich change in color tone.

Furthermore, in claim 2 of the present invention, since a buffer material such as a heat-resistant resin is interposed between the multiple metal spray coatings, various excellent features that the metal spray coating of the outer layer can be more easily separated. It has the effect.
