2. Description of the Related Art In recent years,
BACKGROUND ART Pattern lining products in which various patterns such as a grain pattern, a bamboo pattern, and a stone pattern are applied to the surface of a base material made of a steel material, a synthetic resin material, or the like are widely used as handrails, building materials, and the like.

Conventionally, this kind of pattern lining product has been
A wood grain pattern can be directly applied to the surface of a base material made of steel pipe or the like using several types of coating materials of different colors, a stone surface pattern can be polished on the painted surface, or a pattern can be printed indoors. The decorative decoration made of vinyl chloride was attached to the surface of the base material to make the pattern decoration.

In the method described above, the shape of the finished product is limited, and there is a problem in durability of the pattern decoration. In the above method, it is necessary to completely remove the unevenness of the painted surface by surface polishing and to smooth the surface, and it is required to form a coating film to be considerably thick in order to absorb a work error at the time of surface polishing. In addition, the formation of a coating film having an unnecessarily thick thickness and the accompanying increase in the amount of polishing work have been caused. In addition, if the method of attaching a decorative seal is not good, air may be trapped inside the seal or wrinkles may be formed. There was a problem with gender.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and it is possible to easily form a multi-color decoration having a clearer and three-dimensional appearance. It is an object of the present invention to provide a striped lining method which can be applied and has a high degree of freedom in product shape.

[0006]

According to the present invention, there is provided (A) a step of forming a coating lining layer having irregularities on the surface of a substrate;
(B) a step of shaving off the top of the convex portion of the coating lining layer,
(C) a step of filling the concave portions of the coating lining layer with a coating material different in color from the coating lining layer, and (D) a step of polishing the surface of the coating lining layer to provide a continuous smooth surface. It is.

According to the present invention, the thickness of the coating lining layer can be controlled by employing the steps (A) and (B), and the final thickness of the coating lining layer can be controlled by the steps (C) and (B). (D) It becomes possible by adopting the process. Therefore,
Even if there is some work error at the time of surface polishing, it is not necessary to excessively thicken the coating lining layer, compared to the conventional method,
Effects such as simplification of the painting process, saving of paint, and reduction in the amount of polishing work can be achieved.

In the step (A) of the present invention, when a relatively high-viscosity paint is applied to a substrate in the manner of ordinary spray coating, a paint lining layer having irregular irregularities on the surface is naturally formed. This coating lining layer is used as it is as a coating lining layer having an uneven surface. If the depth or shape of the unevenness formed on the surface of the coating lining layer during coating is not favorable, press the coating lining layer with a pressing roller with an uneven pattern during or immediately after coating to paint the desired unevenness. It is preferable to form it on the layer surface.

As the base material in the present invention, various materials corresponding to products to be manufactured are used. Such materials include steel, alloy steel such as stainless steel, zinc, zinc-aluminum alloy or aluminum-plated steel,
Examples include metal-based materials such as aluminum or aluminum alloys or copper alloys, mortar, concrete-based inorganic materials, polymer cement-based inorganic-organic composite materials, and organic materials such as synthetic resin molded products. For these substrates, in order to improve the adhesion with the coating lining layer,
The surface is subjected to a normal ground treatment.

In the present invention, a metal-based material as a base material,
In particular, mechanical projection and chemical conversion treatment of zinc-iron alloy particles (so-called Z-
It is preferable to use a metal-based material on which a zinc-iron alloy film is formed by S treatment) and subjected to a base treatment.

The invention described in claim 1 of the present application is roughly classified into the following three embodiments.

(1) A case in which the coating lining layer formed in the step (A) is a single color, and the concave portion of the coating lining layer is later filled with a different color paint. (When the purpose is to show the polished surface of a monochromatic stone material.) (2) The coating lining layer formed in the step (A) is formed of a plurality of coating layers having different colors, and will be described later. In the concave portion of this coating lining layer, paint of the same color as each coating layer (even if it is the same color as any coating layer constituting the coating lining layer, it is a different color compared to the coating lining layer) or a different color paint When filling. (When the purpose is to show the polished surface of a marble-colored multi-colored stone material.) (3) The coating lining layer formed in the step (A) is formed of a plurality of adjacent coating bands having different colors. After that, in the concave portion of the coating lining layer, the color of each coating band is the same as that of each coating band (even if it is the same color as any coating band constituting the coating lining layer, it is a different color compared to the coating lining layer ) Or when filling with a different color paint. (The case where the purpose is to present a polished finish pattern surface of a granite or granite-colored multi-colored stone material.) Each embodiment will be described in the above order.

(1) A single-color coating lining layer having irregularities in a thickness range of about 0.1 mm to 10 mm is formed by a method that easily causes irregularities such as spray coating in the step (A), and convexities are formed in the step (B). After shaving off the top of the part, filling the concave part with a different color paint in the step (C) makes the surface of the coating lining layer a continuous plane. Finally, in step (D), the surface of the coating lining layer is polished to remove unnecessary coating film adhering to the surface and to make the surface smooth, so that the final coating lining layer has a thickness of 1 to 4 mm. The stone-like stripes and swirls appear on the design surface. The color tone of the paint to be filled in the step (C) and the color tone of the coating lining layer formed in the step (A) may be distinctly different colors or may be slightly different. In order to exhibit a solid stone-like design surface, it is rather preferable that there is not much difference in color tone.

(2) In the step (A), two to four kinds of paints having different colors are successively sprayed, and the whole coating layer is formed to have a thickness of about 0.1 mm to 10 mm. A coating lining layer is formed to have. In this embodiment, it is preferable that the painted surface is pressed by a pressing roller having a concave and convex pattern between the painting of the first paint and the painting of the second paint to form irregularities on the painted surface. When the tops of the projections are scraped off in the step (B), the coating layer hidden in the surface layer is exposed on the surface, and stripes and swirls appear. The subsequent steps (C) and (D) are exactly the same as in the case of (1).
Eventually, stone-like stripes and swirls with a coating lining thickness of about 1 to 4 mm will appear on the design surface. The color of the paint used in step (C) may be the same as or different from the paint used in step (A), and may be any color that matches the desired pattern formation.

(3) In the step (A), two to four kinds of paints having different colors are simultaneously spray-painted in parallel (so-called multicolor spraying), so that adjacent paint films are painted in different shapes. Unlike the above cases (1) and (2), a lining layer is formed and two or more color patterns appear on the surface of the coating lining layer from the beginning. This is the same as (1) and (2). Also,
The point that the color of the paint used in the step (C) may be the same as or different from the paint used in the step (A) is the same as in the case of the above (2).

In any of the above embodiments (1), (2) and (3), selection of the color of each paint to be used, selection of the thickness of the coating film, and coating lining formed in the step (A) By selecting the degree of irregularity and irregularity of the layer, selecting the height of the top of the coating lining layer to be shaved in the step (B), and selecting the paint to be filled in the step (C), there are various stripes and swirls. A lining layer is obtained.
