Description

The present invention relates to a method for forming a pattern coating, and more particularly to a method for forming a pattern coating applied to the inner and outer wall surfaces, ceiling, floor, and the like of a building.

Conventionally, a method called a combination coating method has been used as one of methods for forming patterns with various colors on the inner and outer wall surfaces, ceiling, floor, and the like of a building. In this method, paints are applied to a roller such as rubber or sponge, then repeatedly pressed against the surface to be coated, and another paint of a different hue is applied in the same way to form various patterns. It is to let you.

However, this method is very complicated and requires a lot of labor and time. In addition, this method requires the skill of the painter, and the finish level is greatly affected by the skill level of the worker, so that it is not always finished with a certain level of quality.

On the other hand, Japanese Patent Application Laid-Open No. 2002-136916 discloses a method of applying a paint discontinuously using a specific roller brush containing a specific paint. The paints that can be produced are limited, and the pattern to be formed is fine due to the hole diameter of the roller brush used, so that only a monotonous pattern can be obtained.

Furthermore, as a method of forming a concavo-convex pattern on the surface of a flat substrate to form a complex pattern, coarse silica sand is blended on the surface of a flat substrate such as an outer wall material on which a ricin coating film is formed. Apply the finish paint or apply the base paint with a flow coater or spray, then spread the silica sand with a sand spreader to form an uneven film with the silica sand, and then apply the base paint in the same way. 1 or 2 times, or as disclosed in JP-A-2002-120532, an overcoating paint having a color tone different from that of the undercoating paint is applied to the surface of the base material to which the undercoating paint has been applied in advance. A method is known in which the entire surface is coated and then scraped off with a coating roller whose surface is not smooth while the top coat is undried to expose a part of the base.

However, these methods have a problem in that the coated flat surface is not smooth, so that dirt easily accumulates, and a large amount of paint is required for coating.

Therefore, the main object of the present invention is to provide a method for forming a pattern coating film having an unprecedented excellent design, which is basically free of irregularities, by coating with a specific roller.

A further object of the present invention is to provide a method for forming a pattern coating film that can form a variety of patterns with excellent aesthetics by using a relatively small amount of paint without depending on the skill level of the painter. It is to be.

The method for forming a patterned coating film according to the present invention includes (1) including a top coat paint having a color tone different from that of the base coat paint on the surface of the base material previously coated with the base coat paint in a flocked painting roller having irregularities on the surface. After that, the method comprises a step of forming an irregular and discontinuous first pattern by rolling the coating roller in contact.

In addition, the method for forming another patterned coating film of the present invention is as follows.
(1) The surface of the base material to which the undercoat paint has been applied in advance is made to include a topcoat paint having a color tone different from that of the undercoat paint in a flocked paint roller having irregularities on the surface, and then the paint roller is contact-rolled. A step of forming an irregular, non-continuous first pattern, and (2) after forming the first pattern, the top coating material is included in all or part of the surface of the substrate. Forming a second pattern by contact rolling the coated roller,
It is characterized by comprising.

Furthermore, in order to arrange the pattern coating film to be formed in a more complicated and irregular manner, the pattern coating film forming method according to the present invention includes a top coating material to be included in the coating roller in the step of forming the second pattern. The amount can be reduced at least less than the amount of top coat included in the coating roller in the step of forming the first pattern.

Similarly, in order to arrange the pattern coating film to be formed in a more complicated and irregular manner, the pattern coating film forming method according to the present invention includes the step of forming the second pattern into the first pattern. This can be performed before the first pattern formed in the forming step is dried.

ADVANTAGE OF THE INVENTION According to this invention, the formation method of the pattern coating film which has the design which has the outstanding design property which has few few unevenness | corrugations fundamentally by the coating using a specific roller can be provided.

Specifically, in the method for forming a patterned coating film according to the present invention, an overcoating paint having a color tone different from that of the undercoating paint is included in a flocked painting roller having irregularities on the surface, and then the coating roller is contact-rolled. In order to apply the topcoat paint in a different color to that of the undercoat paint irregularly and non-continuously, the first pattern with an unseen design that has been blurred until now is formed. Can do.

In another pattern coating film forming method according to the present invention, after the first pattern is formed, the same top coat paint as that in which the first pattern is formed on all or a part of the substrate surface is included. As a result, the size, shape, and arrangement of the pattern are unsatisfactory. It is possible to form the first and second patterns that are discontinuous by rule and have excellent design properties that have not been seen so far.

Furthermore, in the method for forming a pattern coating film according to the present invention, the amount of the top coating material included in the coating roller in the step of forming the second pattern is at least included in the coating roller in the step of forming the first pattern. By reducing the amount from the amount of paint, on average, a second pattern smaller than the first pattern can be scattered in a part of the first pattern and its gap, and the size and shape of the pattern In addition, it is possible to form the first and second patterns that are more emphasized on the irregularity of the arrangement and have an excellent design than ever seen.

In addition, the pattern coating film forming method according to the present invention is contact-rolled to form the second pattern by performing the step of forming the second pattern before the first pattern dries. Since the painted roller also contacts and rolls on the first pattern, at least part of the paint of the first pattern collapses using this painted roller as a medium, and the paint adhered to the convex portion of the painted roller 1st and 2nd pattern excellent in the design property which is not seen until now as a result of adhering to the space | gap of 1 pattern interspersed, and the irregularity of the size, shape, and arrangement | positioning of a pattern was further emphasized It is possible to form a top coat film having

As a result, according to the present invention, it is possible to form a variety of patterns with excellent aesthetics by using a relatively simple work and using a minimum amount of paint as required without depending on the skill level of the painter. A method for forming a coating film can be provided.

Hereinafter, specific embodiments of the present invention will be described in detail.

The base materials to be coated to which the present invention is applied are the inner and outer wall surfaces, ceilings, floors and the like of buildings, and the main base materials used in such parts are concrete, cement base materials such as mortar, lightweight concrete Various building materials such as boards, cellular concrete boards, siding boards, asbestos concrete boards and the like can be mentioned. Moreover, it is also possible to apply to what has the to-be-coated surface in which these surface treatments (surface treatment with a sealer, a surfacer, a filler, etc.) were given to these base materials, and also some coating films were formed beforehand. It can also be applied to those having a surface to be coated.

As the undercoat used in step (1) of the present invention, acrylic resin, acrylic urethane resin, epoxy resin, acrylic epoxy resin, chlorinated polypropylene resin, alkali silicate, alkyl silicate, etc. Various conventionally known paints such as an organic solvent type using an agent and an aqueous type can be used.

Since the undercoat paint is exposed in a portion where the topcoat paint described later is not applied, it is preferable that the undercoat paint is uniformly applied to the entire surface of the substrate except for certain exceptions such as tiles and brick joints.

The painting roller used in the steps (1) and (2) of the present invention may be a roller in which the surface is uneven, or a roller wound with fibers such as a nonwoven fabric. If the pattern coating cannot be irregularly and discontinuously applied while blurring the outline of the pattern, and the second pattern is repeatedly applied and transferred before the first pattern dries Is not suitable for crushing and smearing the outline of the pattern paint film previously applied.

Further, the coating roller used in the present invention must have a smooth surface, and must have irregularities on all or part of the surface. The shape of the concavo-convex portion such as the size of the concavo-convex portion and the height difference is not particularly limited, but the shape, size and arrangement of the concavo-convex portion on the entire surface of the coating roller are preferably irregular.

The structure of the painting roller described above not only works to irregularly and discontinuously apply the pattern coating film while blurring the outline of the pattern to be formed, but also forms a second pattern on top of the first pattern. In this case, the second pattern is applied to the first pattern and the gaps in an irregular and irregular manner without crushing the outline of the first pattern previously painted. As, it also serves to form a pattern coating film in which the first pattern and the second pattern having a very complicated shape are irregularly mixed.

Further, in order to form a pattern coating film having a more complicated shape and emphasized irregularity using the above-described coating roller, the coating roller is included in the step of forming the second pattern. By reducing the amount of the top coat at least from the amount of the top coat included in the painting roller in the step of forming the first pattern, the second pattern which is smaller than the first pattern on average is formed in the first pattern. It is also possible to form the first and second patterns excellent in design that have not been seen so far by being scattered in a part of and part of the gaps.

In addition, by performing the step of forming the second pattern before the first pattern dries, the coating roller that has been contact-rolled to form the second pattern is applied to the paint of the first pattern. The pattern size, shape, and irregularity of the pattern were further emphasized by breaking the at least part of the coating roller and depositing the paint adhering to the convex portion of the painting roller in the first pattern. An overcoating film having the first and second patterns can also be formed.

Therefore, the form of the convex part of the suitable coating roller surface which can exhibit such a function effectively is comprised from the fiber whose thickness is 1-30 mm, such as the hair length planted by the painting roller, or a nonwoven fabric. Preferably, the painting roller used to form the first pattern and the painting roller used to form the second pattern are flocked rollers having irregularities on the surface. For example, the same roller or rollers having different diameters, hair lengths or thicknesses may be used.

The top coat used in steps (1) and (2) of the present invention is not particularly limited as long as it has good adhesion to the undercoat, and conventionally known baking type and normally dry type organic solvents. Various types of paints such as water-based, water-based or solvent-free are included.

Specifically, emulsion paints, water-based paints such as water-soluble resin paints, oil-based paints (kneading paints, blended paints), oil-based paints such as oil-based enamels, alkyd resin paints, aminoalkyd resin paints, unsaturated polyester resin paints, Various paints such as epoxy resin paints, polyurethane resin paints, acrylic resin paints, acrylic silicone resin paints, vinyl resin paints, and other synthetic resin paints, cellulose paints, alcoholic paints, powder paints, inorganic paints can be used, and coloring pigments can be used. It only has to be included.

Also, when painting on the outer wall made of cement-based material, it is desirable to use an alkali-resistant paint, such as the vinyl chloride enamel, synthetic resin emulsion paint (vinyl acetate, acrylic, etc.), acrylic enamel, etc. Paint can also be used.

As the top coat used in the present invention, for example, a normally dry water-based paint such as an acrylic silicon emulsion is preferable. Especially when used outdoors in buildings, weather resistance and water resistance are important. Such paints are commercially available.

The aqueous medium of the water-based paint is composed of water or a mixture of water and an organic solvent.

Specific examples of the organic solvent include hydrophilic organic solvents such as methanol, alcohols such as ethanol, propanol and butanol, alcohol ethers such as ethylene glycol monoethyl ether and ethylene glycol monobutyl ether, and ketones such as acetone and methyl ethyl ketone. It is possible to use a solvent or a mixed organic solvent of the solvent with various hydrophobic organic solvents for paints such as toluene, xylene, ethyl acetate, and butyl acetate.

Further, the clear paint (including color clear paint) used in the present invention is not particularly limited as long as it has good adhesion to the above-mentioned top coat film, and conventionally known printing types and normally dry types. And various organic solvent-based, water-based or solvent-free coating materials.

Hereinafter, the present invention will be described more specifically with reference to examples.

Examples of the top coating used in the steps (1) and (2) of the present invention include water-based paints such as emulsion paints and water-soluble resin paints, oil-based paints (kneading paints, blended paints), and oil-based paints such as oil-based enamels. , Alkyd resin paint, Amino alkyd resin paint, Unsaturated polyester resin paint, Epoxy resin paint, Polyurethane resin paint, Acrylic resin paint, Acrylic silicone resin paint, Vinyl resin paint etc. Synthetic resin paint, Cellulose paint, Alcoholic paint, Powder Various paints such as paints and inorganic paints can be used as long as they contain color pigments. As the top coat paint in this example, an acrylic silicon emulsion paint containing a white brown color pigment was used.

In addition, when painting on the outer wall made of cementitious material, it is desirable to use an alkali-resistant paint, such as the aforementioned vinyl chloride enamel, synthetic resin emulsion paint (vinyl acetate, acrylic, etc.), acrylic enamel, etc. Paint is used.

Next, the formation method of the pattern coating film by this invention is demonstrated according to a painting step.

First, remove the exterior walls of the building to be painted, such as concrete-type panel exterior materials (ALC, etc.) of newly built ordinary houses by using wire brush, cleansing, high-pressure washing, etc. To finish the ground surface smoothly. As the substrate to be coated in this example, the outer wall of a general building made of a cement siding board was used.

In addition, when the exterior wall of the building is a cast-in-place concrete wall of a multi-purpose building, a board exterior material of a factory / warehouse, an aluminum alloy panel exterior material, a stainless steel panel exterior material, a siding board / lass mortar wall of a small-scale ordinary house, etc. In the same manner, it is preferable to adjust the ground (base).

Furthermore, in the case of ALC, etc., where the exterior wall of the building is fragile and porous, after the base is adjusted, the sealer is coated evenly with a synthetic resin emulsion clear, vinyl sealer, epoxy sealer, etc. so as not to form a thick film It is preferable to apply.

Next, after the base preparation and sealer coating are finished, the paint is suitable for the purpose of waterproofing, alkali resistance, acid resistance, insulation, rust prevention, antifouling, etc., and the painting method (brush painting, roller coating, air spraying) suitable for the paint. , Electrostatic coating, roll coater, etc.).

As the undercoat paint, organic solvent type, aqueous type, etc. using binders such as acrylic resin type, acrylic urethane resin type, epoxy resin type, acrylic epoxy resin type, chlorinated polypropylene resin type, alkali silicate type, alkyl silicate type, etc. Various conventionally known paints can be used, but in this example, a brown acrylic silicon emulsion paint was applied as an undercoat on the entire surface using a normal roller. FIG. 1 shows a partially enlarged photograph of a state in which the undercoat paint is applied to the entire surface of the coating base material (building exterior wall siding board) in this example.

When the undercoating is finished, prepare an overcoating with a different color that matches the undercoating, and apply the first overcoating on the outer wall of the building.

This coating is performed by contact-rolling a planted coating roller (made by Otsuka Brush Manufacturing Co., Ltd .: Wooler C (projection hair length: 6 mm) modified to have irregularities) with irregularities on the surface. It was coated by moving it. In addition, the adhesion area and adhesion amount of the paint can be adjusted according to the drying speed of the paint, the area of the outer wall, and the taste.

FIG. 2 shows a photograph of the state of the coating film having the first pattern on the outer wall after the first overcoating. The part copied in black is a coating film having the first pattern and corresponds to the part where the paint is applied by the convex part of the brush roller. In addition, the other portion shown in white is the exposed surface of the undercoat. From FIG. 2, it can be seen that the first pattern is irregularly and discontinuously applied while blurring the outline due to the effect of the flocked coating roller having irregularities on the surface.

Next, the coating roller in which the amount of the top coating material included in the coating roller in the step of forming the second pattern is reduced by 70% from the amount of the top coating material included in the coating roller in the step of forming the first pattern The first and second patterns were formed using

FIG. 3 shows the state of the coating film having the first and second patterns on the outer wall after the second overcoating is applied using the painting roller in which the paint is reduced from the step of forming the first pattern. Is shown in the photo. The portion shown in black is the coating film having the first and second patterns, and corresponds to the portion where the paint is applied by the convex portion of the brush roller. In addition, the other portion shown in white is the exposed surface of the undercoat. From FIG. 3, the first pattern previously formed and formed and the second pattern formed later are spread in a scattered manner so that all or part of the first pattern is blurred by a flocked painting roller. It can be seen that a pattern coating film is formed.

Also, by reducing the amount of the top coating material included in the coating roller used in the step of forming the second pattern from the amount of the top coating material included in the step of forming the first pattern, the first The second pattern smaller than the first pattern is scattered in a part of the first pattern and the voids, and the irregularity of the pattern size, shape and arrangement is more emphasized. It turns out that the 1st and 2nd pattern coating film excellent in the designability which cannot be formed is formed.

According to the present invention, the first topcoating and the second topcoating can be repeated three or more times alternately little by little, but in this case, particularly when the coating area is large or the drying speed of the paint When it is fast, it is necessary to pay close attention to the formation of the top coat film.

As a result, in the method for forming a patterned coating film according to the present invention, an overcoating paint having a color different from that of the undercoating paint is not obtained by causing the coating roller to contact and roll using a flocked painting roller having an uneven surface. It is possible to form a first coating film pattern that is discontinuously applied by rule and has a blurred outline.

In another pattern coating film forming method according to the present invention, after the first pattern is formed, the same top coat paint as that in which the first pattern is formed on all or a part of the substrate surface is included. As a result, the size, shape, and arrangement of the pattern can be changed as a result of the second pattern being scattered in a part of the first pattern and the gaps using the coating roller as a medium. Irregular and non-continuous first and second patterns having an unprecedented design can be formed.

Furthermore, in the method for forming a pattern coating film according to the present invention, the amount of the top coating material included in the coating roller in the step of forming the second pattern is at least included in the coating roller in the step of forming the first pattern. By reducing the amount from the amount of the paint, the second pattern, which is smaller than the first pattern on the average, is scattered in a part of the first pattern and its gap, and the size, shape and arrangement of the pattern The first and second patterns that are more emphasized in the irregularity and excellent in design that has not been seen so far can be formed.

In addition, the blur expression described above makes the coating defects such as roller slip patterns and blurring inconspicuous, so even if these coating defects occur during or after painting, the visual aesthetics are less likely to be lost, and repainting is not necessary. I saved the trouble of doing.

Furthermore, according to the present invention, it is possible to form various pattern coating films having excellent aesthetics by using a relatively simple work and using a minimum amount of paint as required without depending on the skill level of the painter. I was able to.

As mentioned above, although this invention has been demonstrated based on the Example, this invention is not necessarily limited to these. For example, undercoating of a building outer wall is not indispensable, and the pattern coating film forming method of the present invention is sufficiently effective even without undercoating.

The external appearance photograph of the outer wall at the time of performing undercoating by this invention is shown. The external appearance photograph to which the outer wall in which the 1st pattern coating film was formed at the time of performing the 1st top coat by this invention was formed is shown. The enlarged external appearance photograph of the outer wall in which the 1st and 2nd pattern coating film was formed at the time of performing the 2nd top coat by this invention is shown.
