Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming a pattern with a new design on a wall surface of a building or a structure, an inorganic plate-like building material, or the like.

[0002]

2. Description of the Related Art In the field of painting on the interior and exterior walls of buildings by on-site painting, and in-line painting of building materials with concrete, mortar, etc., painting for forming various patterns has been conventionally performed. I have.

For example, after forming a uniform and smooth coating film by spray coating or roller coating, a roller having an uneven surface is rolled before the coating film is cured, whereby the surface of the roller is rolled. There are a method of forming irregularities and a method of forming irregular irregularities by applying a paint containing a large amount of aggregate with a coating machine called a ricin gun.

[0004] However, the textures obtained by these conventionally known methods are not suitable for in-situ painting on interior and exterior surfaces of buildings.
Long drying times are required, and the conditions under which coating is possible depend on the weather. Further, in the case of painting of a plate-like building material on a factory line, equipment for heating or forced drying is required, resulting in a large capital investment.

[0005]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to develop a method for forming a pattern, which differs from the conventional coating method in that the drying time is greatly reduced and no special heating and drying equipment is required.

[0006]

Means for Solving the Problems In order to solve such problems, the present inventors have conducted intensive studies and found that a thermoplastic resin or a hot melt resin is applied in a continuous or discontinuous uneven or fibrous form. The drying time was significantly shortened, and a pattern that had never existed before was successfully formed. The gist of the present invention resides in the following.

On the surface of a plate-like building material or the interior and exterior surfaces of a building,
A pattern forming method, wherein a pattern is formed by applying a thermoplastic resin in a continuous or discontinuous uneven shape or a fibrous shape. The pattern forming method described above, wherein the thermoplastic resin is a hot melt resin. The pattern forming method described above, wherein the hot melt resin is applied using a nozzle type air spray applicator or a spiral spray applicator. The pattern forming method described above, wherein the thermoplastic resin or the hot melt resin is colored with a dye, a pigment, or a paste thereof to an arbitrary color. The pattern forming method described above, wherein a colorful pattern is formed by combining a thermoplastic resin or a hot melt resin colored in two or more colors. The pattern forming method described above, wherein a transparent or colored clear paint is applied after applying a thermoplastic resin or a hot melt resin in a continuous or discontinuous uneven or fibrous form. This will be described in detail below.

The thermoplastic resin used in the present invention is a resin which is solid at room temperature, has fluidity in a heated state, and can be applied by heating and pressurizing. Examples include unsaturated polyester resin, polyethylene, polystyrene, melamine, polyamide, vinyl chloride resin, vinyl acetate resin, ethylene-vinyl acetate copolymer, polyethylene terephthalate, and the like. Furthermore, as a thermoplastic resin in a broad sense, various asphalts, that is, straight asphalt, blown asphalt, modified asphalt, highly dyeable asphalt capable of coloring, and a bituminous resin containing these as a main component can also be used. . In addition, although classified as a part of thermoplastic resin, hot melt resin contains a thermoplastic synthetic polymer as a main component, and waxes as a modifier,
It is a 100% solids mixed resin that does not contain water or solvent at all and contains a plasticizer, a tackifier, an antioxidant, a filler, and the like. In general, it is known for use as an adhesive, and is widely used particularly in the field of the packaging industry. It has features such as being advantageous for bonding impermeable surfaces, such as plastic films and metal foils.

The thermoplastic synthetic polymers as main components include ethyl cellulose, vinyl acetate resin and its derivatives, polyethylene, ethylene-vinyl acetate copolymer, butyl methacrylic resin, polystyrene and copolymer, polyisobutylene, petroleum resin, polypropylene , Polyamide resins, polyester resins and the like are used.

[0010] The hot melt resin generally used as an adhesive is applied to the bonding surface by a coating device called a special applicator having a heating mechanism. However, applicators used for general bonding applications have the function of applying a hot-melt resin on a certain surface, but the function of applying a continuous or discontinuous unevenness or fiber is often used. It is not suitable for use in the present invention because it does not have it.

In the present invention, a thermoplastic resin or a hot melt resin is applied in a continuous or discontinuous uneven shape or a fibrous shape to express a unique texture which has not existed conventionally. For this purpose, it is necessary to use an applicator that can be applied in an uneven or fibrous form. A nozzle type air spray applicator or a spiral spray applicator can be exemplified as one suitable for such a purpose.

[0012] The nozzle type air spray applicator contacts a thermoplastic resin or hot melt resin beat discharged from an application nozzle with pressurized air discharged from an air nozzle adjacent to the application nozzle to form a thermoplastic resin or a hot melt resin beat. It is a known device which realizes fibrous coating by elongating a hot melt resin beet in a slender manner.

A spiral spray applicator is a device in which pressurized air to be brought into contact with a thermoplastic resin or a hot melt resin beat is turned into a rotary jet by rotating an air nozzle, and a spiral coating pattern is realized by the jet. Which is also a known device. This device was originally developed for the purpose of expanding the coating range and widening the coating width by using a spiral coating pattern.

[0014] By applying a thermoplastic resin or a hot-melt resin in an uneven shape or a fibrous shape by combining any one or both of the above-described devices, an uneven pattern expressing a texture which has not existed in the past can be formed. Becomes possible. Alternatively, a more complicated pattern can be formed by rolling a roller having a smooth surface or a roller having an arbitrary pattern onto the application surface immediately after the application of the thermoplastic resin or the hot melt resin. Although this complicated concavo-convex pattern is formed even if it is a non-colored thermoplastic resin or a hot-melt resin, a more complex and diversified pattern can be formed by coloring it in an arbitrary color.

As a method for coloring a thermoplastic resin or a hot melt resin, titanium white, titanium yellow,
Conventionally known various coloring pigments such as carbon black, cyanine blue, and cyanine green, conventionally known various dyes, and pastes thereof can be used.

As the colored thermoplastic resin or hot melt resin, a single color resin may be used, but a plurality of color resins are prepared in advance, and the applicator is applied under computer control to apply the resin. It becomes possible to form an even more complicated colorful pattern.

The thermoplastic resin or hot melt resin is firmly fixed to the coated surface by cooling to a room temperature to form a patterned surface, so that a special heating and drying device is not required after coating.

The pattern surface formed of a thermoplastic resin or a hot melt resin has a necessary and sufficient strength. However, by applying a clear paint to the pattern surface, the weather resistance of the pattern surface is improved, Can be obtained. By adding the necessary additives to the clear paint, it is possible to impart antibacterial properties, anti-algal properties, and the like.

When the clear paint to be applied is transparent,
It is a finish that makes use of the colorful pattern on the pattern surface and the color tone of the base, but by combining the clear paint with a thin and appropriate color, a color clear paint, the combination of the color tone of the base and the colorful pattern of the pattern surface, It is also possible to form a large number of complex colorful patterns.

[0020]

BEST MODE FOR CARRYING OUT THE INVENTION Examples will be described below for better understanding of the present invention. Needless to say, the present invention is not limited to the following examples.

[0021]

Example 1 In a building exterior wall painting work, a hot melt resin containing ethyl cellulose as a main component is applied to a wall surface after primer application and intermediate application using a nozzle type air spray applicator, and a roller is applied immediately after application. The applied surface was pressed to form an uneven surface.

[0022]

Example 2 In a building inorganic exterior wall board coating line, a hot melt resin mainly composed of an ethylene-vinyl acetate copolymer colored brown with a coloring dye was applied using a spiral spray applicator. Immediately after the application, the application surface was rolled with a roller to form an uneven pattern surface.

[0023]

[Results] The uneven surface of Example 1 and Example 2 was hardened simultaneously with cooling of the hot melt resin to form a strong outer wall decorative layer.

[0024]

According to the present invention, since a long drying time is required, the coating is affected by the weather, and the interior and exterior of the building is coated on the site, and the decorative layer is applied to a plate-like building material which requires a heating and drying facility. In this way, patterns can be formed in a very short time, greatly reducing the effects of weather at the painting site, and eliminating the need for equipment such as heating and drying during painting in factories. In this respect, the method has a great advantage over the conventional method. And,
The texture of three-dimensional unevenness that did not exist in the past was realized,
This makes it possible to create unique building wall decorations and building material patterns. In addition, according to the pattern forming method of the present invention, since there is no solvent volatile matter generated at the time of application and drying of the conventional solvent-type paint, the coating worker does not inhale the solvent volatile matter and is safe and air free. It is an environmentally friendly method without polluting.
