Abstract

PROBLEM TO BE SOLVED: To provide a method for applying a rust pattern which becomes a naturally generated mentally calm pattern wherein uneven parts of rust become a finely dispersed state and there is no boundary in density or hue as if rust is generated before one knows with the times though maintenance has been kept, is fitted to mass-production though there is no principle in pattern, not changed in rust state because different from rust generated by the surface corrosion of a metal and can maintain the status quo for ever. SOLUTION: Fine beads are mixed with a paint, which imparts an antiquated hue to the surface of a metal to which the rust pattern must be applied, to prepare an undercoat paint and an intercoat paint, which contains pigment imparting a rust hue to the surface of the metal and has a rust feeling, is prepared and the undercoat paint is applied to the surface to which degreasing substrate treatment is applied of a material to be coated to disperse the fine beads in an irregular pattern group and, after the beads are fixed by curing the undercoat paint, the intercoat paint is applied to the undercoat paint layer and the coated material to be coated is wipen using an organic solvent. The antiquated color of the undercoat paint and the rust color of the intercoat paint are expressed on an irregular pattern by the intercoat paint hooked with the beads group though the coated material to be coated is wiped.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to a method of painting a rust pattern for treating old-fashioned interior materials.

[0002]

2. Description of the Related Art Even if painted, the metal members of a building are old and rusted for a long time, but this is because it exudes European antiquity, nobility and deepness. Building is preferably used as a relaxing place. In spite of this rare existence, attempts have been made to artificially paint building materials as if they were old and rusted.

Heretofore, in this attempt, a paint having a color tone such as rust was simply and uniformly applied, so that there was no pattern that appeared as a natural phenomenon. Was not felt.

[0004] Looking at the state of rust generation in an existing building that is preferably used, even if it has been cleaned for a long time, even though it has a clean feeling, irregular rust spots appear from natural occurrence, This exudes a sense of cleanliness and antiquity. However, it was difficult to spontaneously express this mottled pattern.

[0005] For example, the expression of a pattern is expressed by hand movement, for example,
If the spray is to be realized as a combination of this moving change and speed, it will not only require skillful techniques, but also form the expression of the individuality of the worker, and even if it is suitable for a single piece of work, In the case where uniformity is required to a certain extent as in the above case, it is not appropriate to establish a mass sales system.

Further, since the rusted portion is swollen due to the oxidation phenomenon, in order to express this, unevenness is formed by applying an emulsion paint unevenly, and a rust-colored paint is applied thereon with a roller. However, in this case, the appearance of rust strength is created by the embedding of the emulsion paint, so it becomes an image of a dirty ruin without maintenance, and it is beautiful in expressing traditional age Cannot be taken.

In the case of painting and the like, a transfer sheet is often used to take a mass production posture. However, if a rust pattern is expressed by this method, it is too patterned and a natural expression that calms down the heart peculiar to rust. It is not appropriate to use this method either, because it does not result in a natural expression having fine irregularities and no boundaries in shades and colors.

On the other hand, a method is currently used in which a metal member such as iron or copper is corroded by a chemical to actually generate rust on the metal surface. In this method, oxidation of the metal surface progresses for a long time, the state of rust changes, and finally, the metal member itself cannot keep its shape due to corrosion.

[0009]

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, the present invention is different from the conventional method in that rust has been generated over time even though care has not been omitted. As shown, rust irregularities are fine and dispersive, resulting in a naturally occurring calm pattern with no boundaries in shades and colors, suitable for mass production despite the lack of principle of the pattern, and corrosion of the metal surface It is an object of the present invention to provide a rust-pattern coating method that does not change the rust state because it is not rust due to the rust pattern and can keep the current condition forever.

[0010]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a method for producing a rust pattern, wherein the surface of the metal has fine beads on a paint having an old color tone. While mixing the ball to prepare the undercoat, the metal surface is mixed with a rusty intermediate paint containing a pigment with a rusted color, and the surface of the material to be coated is subjected to a degreasing ground treatment, and then the undercoat is prepared. The beads are scattered in the mottled group by applying the paint, and after the beads are fixed with the curing of the undercoat paint, the intermediate paint is applied, and then the organic paint is wiped with the organic solvent. It is an object of the present invention to provide a method of coating a rust pattern, wherein the old paint and the rust color of the undercoat paint are expressed in a spotted pattern by the intermediate paint remaining on the ball group.

According to the above configuration, when the undercoating paint containing beads is applied, large and small groups of beads are formed, and between the groups are rough portions where the beads are scarcely present. In addition, since the density changes gradually during that time, no boundary is generated. Since the beads are fixed by drying or baking of the paint, the beads do not flow even if the middle coat is applied thereon. Appears as an undercoated old color, portions other than the beaded balls appear as a middle coat rust color, and the rust appears as a spotted pattern as a whole. This is because, in the wiping of the intermediate coating, the beads other than the group of the beads are caught by the beads and the intermediate coating remains.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, a material 1 representing a rust pattern may be not only an exterior material and an interior material of a building, but also a fitting and an ornament. Further, the material does not need to be a material corresponding to the color in which rust is generated, and for example, copper rust may be formed in an aluminum material. In addition, not only new fabrics but also existing fabrics may be used.

[0013] In any case, the undercoat is applied after the undercoating treatment. However, if it is an existing one, it is necessary to remove it when rust is generated, and it is still new and needs to be cleared. Unless the treatment or coating treatment is stable, a rust preventive treatment such as a chromate treatment or a primer treatment is performed to form a stable undercoating base.

The color tone of the undercoat 4 is basically desirably an old color when an oxide film is formed on the surface of the target metal where rust is generated. For example, when iron is rusted, black brown is desirable, and when copper is rusted, greenish black brown is desirable.

Since the beads need to be fixed, the undercoat is cured by natural drying, artificial drying, baking, etc., and then the intermediate coating is applied. The color of the intermediate coating 5 is bronze. Is preferably green-blue, iron is an iron rust color, and brass is an intermediate color. But,
The pigment material is not particularly limited. In any case, a paint containing a large amount of pigment for residual and having a rust feeling is selected. The intermediate coating 5 may be a baking type or a normal temperature type.

As the organic solvent for wiping, alcohol, thinner, or the like is used. If the organic solvent is contained in a cloth, buff, or the like and the intermediate coating is wiped off, the area where the beaded balls 3 are present becomes a completely undercoated surface. On top of this, a clear (fluorine-based, urethane-based, etc.) is applied as an overcoat 6 and finished.
Since the presence of the beaded beads is uniformly scattered as a whole, a rough rust is exhibited even if the surface of the beads is touched.

The types of the undercoat 4 and the intermediate paint 5 are not particularly limited. For example, urethane, acrylic, epoxy, alkyd and unsaturated polyester resin paints are preferred. Regarding the application method, brush coating, spray coating, electrostatic coating, flow coating, dip coating, roller coating, and the like can be appropriately used.

[0018]

As described above, according to the present invention, an undercoat and an intermediate coat are applied to a material such as a building material which is to be looked old, and the intermediate coat is wiped off. There is an excellent effect that a well-maintained clean rust can be expressed by naturally occurring spots. ,

[0019]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An aluminum alloy metal plate alumite-treated material is used as a material 1 to be coated. First, degreased as a pretreatment, and then a chromic acid treatment and a zinc chromate film 2 to increase corrosion resistance. (Figure 1). This is called a chromate treatment. In this case, it is immersed in a treatment solution and then washed with water. After the surface of the chromate treatment has dried, a paint 4 containing beads 3 is applied by spray coating as an undercoat. In this case, a paint in which the glass bead balls 3 were uniformly mixed into a black-brown urethane-based resin paint was used.

After the undercoat 4 is dried, the paint 5 to be wiped thereon is applied as a middle coat with a spray gun (FIG. 2). As the intermediate coating paint 5, a mixture of a patina powder as a pigment and a urethane resin paint was used.

After applying the intermediate paint 5, the intermediate paint 5 is wiped off with a cloth containing a thinner (FIG. 3). As a result of this wiping operation, the intermediate coating paints 5, 5,... Remain only at locations other than the groups P, P,... Of the bead balls 3, and a rust between the black-brown surface of the undercoating paint 4 and the green-blue color. A mottling was formed.

After the surface showing the mottled pattern was dried, a fluorine-based clear top coat 6 was sprayed and dried (FIG. 4). Regarding the finish, even though the surface of the aluminum alloy was applied, patina appeared on the bronze surface as if it were patchy, giving a well-maintained clean rust.
