Description of the Related Art Heretofore, exterior materials such as an outer wall material having an uneven pattern formed of a lysine coating film on a substrate surface have been widely used. The formation of the lysine coating film is performed, for example, by applying a finish coating compounded with coarse silica sand to the surface of the base material, or applying a base coating by a flow coater or a spray, and then spraying the silica sand with a sand sprayer. It has been carried out by spraying and fixing, forming an uneven coating film formed of silica sand, and applying the topcoat once or twice in the same manner as in the case of applying the base paint. In addition, tile patterns are also widespread, such as the formation of a tile coating, for example, after coating the base paint on the base paint with a flow coater or spray,
This has been done by painting the tile base with a tile gun and then applying one or two overcoats.

耐ブロッキング性に問題があった。In recent years, demands for deep grooved or complicated embossed patterns have been increasing in response to the trend toward higher-grade design of exterior wall materials. However, the above-mentioned conventional coating method has originality. In addition, there was a problem that the painting could not follow the demand for a new pattern. For on-site coating, there is also a method of applying a paint containing silica sand of No. 2 to 4 and then scratching it with a trowel to pattern it. However, when a flat plate is stacked in such a state, there is a problem in blocking resistance such as damage to a coating film.

になる程度が適当である。BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail. In the method for forming a decorative coating film of the present invention, as the base material, various materials such as a metal plate used for a building exterior wall material and the like and an inorganic plate can be used. Step (a) The undercoat paint used in step (a) of the present invention only needs to have adhesion to the base material and to have adhesion to the intermediate paint used in step (c). Conventionally known baking molds,
Various paints such as an organic solvent type such as a normal dry type and an ultraviolet curable type, an aqueous type or a non-solvent type can be used. Specifically, the undercoat paint is composed of a resin component as a binder, an essential component, and, if necessary, an organic solvent, a solvent such as water, a coloring pigment, an extender pigment, and various additives. ing.
As the resin component, for example, an acrylic resin, an alkyd resin, an epoxy resin, a silicone resin, a fluororesin, one or a mixture of two or more of inorganic silicon resins,
Alternatively, a resin composed of a modified product thereof (optionally used in combination with a curing agent) is suitable. In the step (a), such a base coat is applied to the surface of the base material by a coating means such as a spray, a roller or a brush. The coating amount is the dry film thickness,
For example, 30 to 100 μm, preferably 40 to 80 μm
Is appropriate.

くくなり、美しい引っ掻き模様が形成しにくくなる。 Step (b) The particle size of the silica sand used in step (b) of the present invention is 0.3
In order to control the thickness of the intermediate coating film in the next step (c), the silica sand is sprayed while the undercoating film is not yet dried at a thickness of 1.5 to 1.5 mm, preferably 0.5 to 1.0 mm. To the undercoat. The spraying amount is, for example, 5 to 500 g / m 2 , preferably 30 to 200 g / m 2 . In addition,
When the particle size is less than 0.3 mm, the three-dimensionality of the resulting coating film is poor, which is not desirable in terms of design. On the other hand, when the particle size exceeds 1.5 mm, the drying property is undesirably reduced. It is desirable to use silica sand having substantially the same particle size so as to have a uniform film thickness when an intermediate coating film described later is pressed. If the amount of spraying is less than 5 g / m 2, it is difficult to obtain a uniform coating film in the next step of pressing the intermediate coating with a roller or the like. On the other hand, when it exceeds 500 g / m 2 , it is difficult for the silica sand to be dragged and moved in the steps (d) and (iii), and it is difficult to form a beautiful scratched pattern.

To 1000 parts by mass, preferably 300 to 700 parts by mass. When the amount of the colored silica sand is less than 100 parts by mass, the drying property is deteriorated. On the other hand, when the amount is more than 1000 parts by mass, the strength of the coating film and the workability of coating are deteriorated. If the particle size of the colored silica sand is smaller than 0.05 mm, it is not preferable in terms of design. If the particle size is larger than 0.3 mm, it is difficult to suppress the particles with a roller or the like in the steps (d) and (i). As the paint, various known paints such as a baking type, a normal dry type, an ultraviolet curable organic solvent type, an aqueous type or a non-solvent type can be used. Specifically, the resin component and colored silica sand are essential components, and if necessary,
It is composed of a mixture of an organic solvent, a solvent such as water, a coloring pigment, an extender pigment, and various additives.

固着させる。 Step (d) In step (d), the following steps (i) to (iii) are performed while the intermediate coating film is not dried. In the step (i), the intermediate coating film is pressed down to the tip of the undercoat film of the silica sand sprinkled in the step (b) to reach the cuff, thereby obtaining a substantially smooth coating film. The intermediate coating film (paint) that has become excessive due to the pressing may be removed. For example, a roller is suitable as a method for suppressing the intermediate coating film, and examples of the material of the roller body to be used include plastics such as polyethylene, polypropylene, and vinyl chloride, metals, and cement. In the case of large-scale line coating, that is, pressing down on a substrate conveyed on a conveyor at a factory, using a heavy-weight roller body such as metal or cement, pressing down is performed by its own weight. Method and Tokusho Sho 5
An appropriate method is to use a head cutting device described in JP-A-9-4190 and perform leveling. In the step (ii), silica sand having a particle diameter of 1.0 mm to 4.0 mm and having a particle diameter larger than that of the silica sand sprayed in the step (b) is sprayed on the surface of the pressed intermediate coating film in the step of intermediate coating. Affix to film.

る。The silica sand is sprayed in the step (iii) by dragging to form a scratch pattern on the surface of the intermediate coating film and to impart blocking resistance to the coating film. The silica sand has a particle size of 1.0
If it is less than mm, the drawn streaks are fine and the scratch pattern becomes unclear, while if it is more than 4.0 mm, it tends to fall off from the intermediate coating film, which is not preferable. The application amount of silica sand is 10 to 1000 g / m 2 , preferably 50 to 50 g / m 2 .
0 g / m 2 is appropriate. If the amount is less than 10 g / m 2 or exceeds 1000 g / m 2 , the design will deteriorate. (Iii) In the step, the surface of the intermediate coating film is rubbed while being held down with an iron, a rubber sheet, or the like, and the silica sand fixed to the intermediate coating film is dragged and moved, for example, by about 10 to 100 mm. A scratch pattern is formed on the film surface.

It is composed of a resin component as an essential component, and if necessary, a solvent such as an organic solvent or water, a coloring pigment, a dye, an extender pigment, and various additives. As the resin component, for example, acrylic resin, alkyd resin, silicone resin,
A resin made of one or a mixture of two or more kinds such as a fluororesin and an inorganic silicone resin, or a modified product thereof (in some cases, used in combination with a curing agent) is suitable. The coating amount is suitably about 20 to 100 μm in dry film thickness. By applying a clear coating to the surface of the intermediate coating film, it is possible to prevent dirt and silica sand from falling off. In addition,
The clear paint may be applied before the intermediate coating film is dried, or may be applied after drying.
