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 hard or flexible coating film used for wall coverings, flooring materials or tables.

[0002]

2. Description of the Related Art Hitherto, a method of forming a natural stone-like design by combining different color paints has been proposed. For example,
In the invention disclosed in Japanese Patent Publication No. 3-42943, there is a technique of spraying, pressing, and polishing different colors of paint. Further, in the invention disclosed in Japanese Patent Application Laid-Open No. 64-66353, a paint to be a dotted pattern portion and a paint to be applied to other portions are divided, and only the pattern portion is applied first, and the other portions are colored. This is covered with a coating material in which a different color paint using an aggregate is mixed, and is polished until the paint of the pattern portion appears.

[0003]

In the present invention, in contrast to the conventional paints of the same kind, which were made to be multicolored or blown apart, different kinds of paints or different kinds of materials were combined.
It is another object of the present invention to obtain a varied finish at the boundary between the paint and the paint or another material.

[0004]

Among the methods for forming a coating film of the present invention, the most characteristic steps are A, B, C and D described below . In the step A, the thick coating 1 by pigment or aggregate coloring is applied to concrete, mortar,
It is to be applied to the underground such as silicon cal board, slate board, plywood, woven fabric, non-woven fabric and plastic mesh. For painting, a spray gun having one or a plurality of nozzles, a pressure gun, a roller, or the like is used. The step B is performed by coating a paint that can be used in the step A on a release base such as a release paper or a Teflon plate, drying and peeling the coating, or a shell, natural stone or the like. A thin sheet, a single color or a striped or flowable plastic sheet made into a shredded paper pattern with a size of several mm to about 10 cm (these are collectively referred to as scattered chips 2) is the coating 1 in the step A which has not been dried. Alternatively, it may be scattered while being embedded from the surface side of the paint 1 in an uncured state. The step C is
After drying or curing with the scattered chips buried,
Polishing is performed until the entire surface becomes smoother (or to a state in which some concave portions are left). Of course, A as it can be seen from the description, B, is due Rinurimaku formed in the order of C performed
You.

The above description will be described with reference to the drawings, which is a sectional view taken along lines a, b, and c of FIG. 1 and corresponds to steps A, B, and C of the present invention. FIG. 1A shows a state in which the thick paint 1 is applied on the base 10. FIG. 1B shows a state in which the scattered chips 2 are scattered on the thick paint 1 while being pressed by the rollers 11. And
FIG. 1C shows a state in which polishing is performed by the sander 12 after the scattered chips are scattered.

[0006] Furthermore, the step D
Is added. In the step D , after the steps A and B or the steps A, B and C where the recesses are left, the paint 1 and the scattered chips 2 are placed in the recesses on the dried or cured coating film surface.
Is a step of filling the coating material 3 having a different color and polishing the coating film surface after the coating material 3 is dried or cured . In addition to coatings
It is also possible to add a process to add gloss,
In order to give a luster, the step C or the step E of applying a clear paint after the step D is completed.

FIG. 2 is a cross-sectional view showing a case where after the steps A and B, a paint 3 different in color from the thick paint 1 is filled and the steps D and E are performed. FIG. 2A shows a state in which the thick paint 1 is applied on the base, and FIG. 2B shows a state in which the scattered chips are pressed down after being scattered. In the partially enlarged view, there is a dent around the scattered chips. It is shown that.
FIG. 2C shows a state in which the entire surface is polished after the step of filling the concave portion with the paint 3 of a different color (not shown). FIG. 2D shows a state where the clear paint 4 is applied to the entire surface after polishing.

Hereinafter, the paint used in the present invention,
The means will be described in detail. Thickening paint 1 used in step A is a synthetic resin emulsion or cement, rarely a water-soluble resin or a solution-type synthetic resin as a binder, and has a high viscosity and can be thickened at one time. Paint. In the paint 1, either the pigmentation or the aggregate coloring may be used as the coloring form, and when painting, a single head gun or a multiple head gun is used. In order to approximate the luxury of the finish to natural stone, it is better to use two or three or more colors, and it is better to use an aggregate coloring and the aggregate is in a mixed color system. A mixed color system is, for example, white, black,
It refers to a gray colored aggregate that has been devised in terms of its color, particle size, and weight ratio.

The objects to be coated with the paint 1 are the same as those mentioned above, such as concrete and siding boats that make up a building, such as various plywoods and textiles that can be later attached to or punched into the building. Alternatively, there are plywood and metal plates that make the tabletop.

Next, the scattered chips 2 to be scattered on the thick coating 1 do not need to be the same cement type or synthetic resin emulsion in terms of the composition as the coating 1, but are coated with a different color coating. There are dried paint pieces or shells, natural stone sheets, monochromatic or manuscript, and flowable plastic sheets. Sheet thickness is 1-3
mm, and it is used in the form of a suitable shred with a hand of about several cm to several tens cm. Spraying of the scattered chips 2 on the paint 1 can be performed by placing them by hand or by using a brush roll. The spraying amount is 1/10 to 2/3 of the whole when viewed from the area.

In the step D , as the coating material 3 to be filled in the concave portions on the surface of the coating film, those exemplified as usable for the coating material 1 can be used. The filling method is a manual method such as a spatula or iron, a doctor knife coater,
A coating machine such as a reverse roll coater can be exemplified. If this filling is performed after the step B and after the step C,
Since the surface is smoother after the step C, the filling can be performed efficiently and reliably.

The composition of the clear coating material 4 used in the step E is not limited as long as it is a transparent and weather-resistant coating film after coating and drying. For example, there are acrylic resin paints, urethane resin paints, fluorine resin paints, and acrylic-silicone resin paints, regardless of whether they are water-based or solvent-based. Examples of the coating method include a roller, a brush, a spray, a roll coater, and a curtain flow coater.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to embodiments. Reference Example 1 A 45 cm square, 6 mm thick asbestos cement plate was used as a base, and the surface thereof was an acrylic synthetic resin emulsion paint. The color number CT-15 of Chinatone, trade name, manufactured by Kikusui Chemical Industry Co., Ltd. Was applied to obtain the step A.
In addition, this China tone is a three-color, three-headed gun-painted skin-based paint with aggregate coloring.
No. 15 is composed of white sesame, dark pink, and red rust. In addition, in the case of white sesame, cold water sand and a little obsidian are used as aggregates. The dark pink color is a combination of cold water sand, slightly light gray colored cold water sand, and the red rust color is a combination of cold water sand, dark brown and yellow colored cold water sand. In the step A, the application amount of the three colors was set to 6 kg / m ² .

On the other hand, for the scattered chips prepared in advance, coating film pieces were prepared. The coating film piece was an acrylic synthetic resin emulsion paint as a paint, and a dry paint film was obtained from Natural tone color number NT-13 manufactured by Kikusui Chemicals Co., Ltd., which is also a skin paint. (still,
NT-13 uses cold water sand, light yellow colored cold water sand, and a small amount of brown cold water sand as the colored aggregate. In order to obtain a dry coating film, the above coating material was applied on a release paper by a spray gun, allowed to dry naturally for 2 days, and then peeled off from the paper. In order to obtain scattered chips, the coating film was cut into a suitable size by hand.

After coating Chinatone, which is a skin-based multicolor paint, on the asbestos cement board, the scattered chips are scattered by hand while not being dried, and then the scattered chips are undercoated with a thickening paint 1 using a pressing roller. The other was to keep the surface almost smooth so that the post-process polishing work was easy. The above is the step B.

Three days after the pressing treatment, the undercoat thick coating 1 was dried, the surface was roughly ground with a # 20 disk sander, and then polished with a # 100 finishing sander. By the two polishing steps, the step C is completed. The resulting coated plate had a beautiful marble appearance.

Example 1 The same procedure as in Reference Example 1 was carried out until the polishing step. Pigment-colored synthetic resin emulsion paint, 78% pigment volume concentration, yellow Filled with putty and spatula. After a lapse of 24 hours, the entire surface was polished again with a # 100 finishing sander. The obtained coated plate had a shape in which only the periphery of the scattered chips was framed, and a coated plate with a beautiful marble appearance was also obtained.

In Reference Example 2 and Example 2, a transparent acrylic silicon resin paint was applied at 100 g / m ² to the coated plate obtained by the method of Reference Example 1 and Example 1.
Was applied at the application amount. The resulting painted plate was shiny and more similar to a polished finish.

REFERENCE EXAMPLE 3 The same asbestos cement board as in Reference Example 1 was used as a base for coating. The undercoat thick coating was coated with the color number CT-9 of Chinatone used in the previous example. This CT-9 is composed of three colors of white sesame, white and gray, and includes cold water sand and a small amount of light yellow colored cold water sand in white, and cold water sand and gray colored cold water sand in gray. Is included.

On one of the scattered chips, a coating film piece made of a cement paint and a bivalve shell were prepared. Cement-based paint is composed mainly of white cement, cold water sand, sensui, viscosity modifier, and yellow pigment. Water is added and kneaded into a 3 mm thick release paper with a frame. It is obtained by curing the product and dividing it appropriately.

While the undercoat thick coating applied to the asbestos cement board was uncured, the cement-based coating film pieces and shells were scattered by hand, and the entire surface was again pressed by a pressing roller. After the pressing process, the painted plate that passed 3 days is also #
Polishing was performed with a 20 disk sander and a # 100 finishing sander. The resulting painted board had a beautiful marble finish.

REFERENCE EXAMPLE 4 A polyester nonwoven fabric (basis weight 8
0g), and the thick paint used as the undercoat was a skin paint having the same color as that used in Example 5 above. The applied amount was 6 kg / m ² for the three colors, and 80 g / m ² of a dark gray emulsion paint was applied and dried in advance to fill the nonwoven fabric.

On the other hand, scattered chips were prepared by crushing plastic artificial artificial stones, Marveglan colors SB and GY (trade name, manufactured by Nippon Shokubai Chemical Co., Ltd.) to a size of 4 mm to 12 mm. On the other hand, as a scattered chip, a plastic sheet obtained by coloring an acrylic resin with a pigment and having a thickness of 2 mm and being made black and translucent white and crushed to a size of 4 mm to 10 mm was prepared.

While the undercoat thick coating applied on the nonwoven fabric was not cured, the plastic-based scattered chips were scattered by hand, and the entire surface was pressed by a pressing roller. Three days after the pressing, the coated nonwoven fabric was polished with a # 100 polishing machine until the entire surface became smooth. The resulting product had a beautiful red granite finish.

[0025]

According to the method of the present invention, the same kind of paint is conventionally sprayed or sprayed separately to obtain a natural stone-like finish. Will be clearly understood. In addition, the texture can be changed when using different materials. In particular, when shells are used for scattered chips, the scattered chips seem to be fossilized at first glance and can create a tasteful design with a texture closer to natural stone, like rock accumulated over many years. .
