Description

The present invention relates to a paint for forming a multicolored pattern, a set product of a paint for forming a multicolored pattern and an enamel paint, a method for forming a film of the paint for forming a multicolored pattern, a painted article, and a method for producing a paint for forming a multicolored pattern.

In recent years, as a finishing material for the outer wall of a siding board (also referred to as a sanding outer wall), there is a demand for a finishing material for a high-class design or a finishing material that makes use of the underlying design, instead of the enamel paint that has been conventionally used.

For example, in Patent Document 1, as a method of repairing a building exterior material, "after removing pollutants on the old coating film of a siding board having a design property, an undercoat coating film (clear coating film) is formed, and this undercoat film is formed. "A method of repairing a building exterior material that forms a topcoat film (clear coating film) on the surface of the coating film" is disclosed, thereby "a coating film of a building exterior material while maintaining a high degree of design such as an existing colorful pattern". It is possible to repair. "

Japanese Patent No. 6284291 (Claim 1, Claim 2, Effect of Invention) Japanese Unexamined Patent Publication No. 2006-326494

However, in the method disclosed in Patent Document 1, since the undercoat coating film and the topcoat coating film are clear coating films, it is necessary to take a sufficient time in the removal step so that contaminants on the old coating film do not remain. .. If contaminants remained, the stains were noticeable even after repair. In addition, cracks in the base could not be hidden. Further, since ultraviolet rays and the like are transmitted through the clear coating film, there is also a problem that the base material is easily deteriorated.

In this regard, it is conceivable to use an enamel paint in order to conceal cracks and dirt on the outer wall of the siding and prevent the transmission of ultraviolet rays and the like to the substrate. However, the finished appearance became a single color, and even if the underlying pattern could be utilized, the pattern could not be utilized, and the design was deteriorated.

Therefore, it is conceivable to apply a multicolored pattern paint having excellent designability on the enamel paint or the like. The multicolored pattern paint is a paint that is often used for the outer wall of houses, etc., and JIS K-5667 states that "the multicolored pattern paint is a suspension of liquid or gel-like particles of two or more colors, and is used once. It is a paint that can be scattered by painting "(JIS K 5567-2003 1. Scope of application, remarks).

As a method of applying the above-mentioned colorful pattern paint, there are spray painting and roller painting. Among them, spray painting has good workability and can obtain a uniform color pattern (less coating unevenness). However, since there is a problem of paint scattering in spray painting, roller painting is often performed especially in densely populated residential areas.

However, roller coating of a multicolored pattern paint has poor workability, and it is very difficult to obtain a uniform color pattern on the coated surface (problem of uneven coating). Therefore, although there is a method of pressing with a spatula or a trowel to finish evenly immediately after application with a sand bone roller (Patent Document 2 above), the pressing process is increased and the construction cost is increased. It was.

Further, in the roller coating, there is a problem that liquid or gel-like color particles are difficult to adhere to the roller surface when the multicolored pattern paint is contained in the roller. Therefore, it has been practiced to use a mesh-like perforated roller (a porous roller such as a sand bone roller or a spongy roller) to impregnate a multicolored pattern paint. However, sand bone rollers, sponge rollers, and the like are more expensive than commonly used wool rollers and brushes, and there is also a problem that the construction cost is increased.

The present invention has been made in consideration of the above-mentioned matters, and is a paint for forming a multicolored pattern, which is easy to apply using an inexpensive wool roller or a brush and has less uneven coating (inconspicuous), and a multicolored pattern. It is an object of the present invention to provide a method for forming a coating film for forming. In particular, it is an object of the present invention to provide a paint for forming a multicolored pattern, which is most suitable for finishing and repairing (repainting) the outer wall of a siding board, and a method for forming a paint for forming a multicolored pattern.

In order to solve the above problems, 2 to 20% by weight of micro-colored flakes that pass through a sieve having a mesh size of 200 μm and a plurality of micro-colored flakes that pass through a sieve having a mesh size of 2.8 mm and do not pass through a sieve having a mesh size of 212 μm. It was used as a paint for forming various patterns, including macro-colored flakes of color. It is preferable to use micro-colored flakes that pass through a sieve having an opening size of 100 μm.
Here, the fact that the paint of the present invention is defined as "a paint for forming a multicolored pattern" does not correspond to the case where the paint of the present invention is "a suspension of liquid or gel-like particles of two or more colors". Strictly speaking, it is considered that it does not belong to the category of "multicolored pattern paint" defined by JIS K-5667 described above.

This paint for forming a colorful pattern is easy to apply using an inexpensive wool roller or brush, and moreover, there is little uneven coating (less noticeable) due to the bias of the colored flakes that form the pattern, and the finish is beautiful.
When the conventional multicolored pattern paint is used, the coating film finished after painting has a space between the colored particles that form the pattern, and the part with few colored particles does not cover the base color, and the base color is also a multicolored pattern. Was used as part of. Therefore, when the color difference between the colored particles and the base color becomes large, the distance between the colored particles in the finished coating film becomes non-uniform, resulting in uneven coating.
However, in the above-mentioned paint for forming a multicolored pattern, by almost covering the base with micro-colored flakes, it is possible to give a sense of unity in color tone and reduce coating unevenness.

It is preferable that the micro-colored flakes and the macro-colored flakes are paints for forming a multicolored pattern containing an acrylic silicone resin and a pigment.

Acrylic silicone resin is particularly excellent in weather resistance. Therefore, by using colored flakes containing an acrylic silicone resin and a pigment, it is possible to realize a coating film having excellent durability with little change in color tone of the colored flakes over time.

Further, it is also preferable that the macro-colored flakes of a plurality of colors are paints for forming a multicolored pattern, which contain colored flakes having the same color tone as the micro-colored flakes.

In this paint for forming a colorful pattern, uneven coating due to the deviation of macro-colored flakes becomes less noticeable.

The paint for forming a colorful pattern is suitable for repainting a surface to be painted such as an outer wall. In particular, it is most suitable for repainting the outer wall of siding.

The above-mentioned problem is a set product of the paint for forming a multicolored pattern and the enamel paint described in any of the above, and the micro-colored flakes and the clear paint contained in the paint for forming a multicolored pattern are mixed with a solid content ratio of 100:39. It can also be solved by a set product of a paint for forming a multicolored pattern and an enamel paint in which the color difference ΔE between the blended paint for measuring the color difference and the paint for enamel paint is 5.0 or less. Enamel paint is used as a base paint for paints for forming various patterns.

Specific examples of the method for forming a coating film for forming a multicolored pattern include an enamel coating film forming step in which an enamel coating film is applied to the surface of a surface to be coated such as an outer wall to form a film, and this enamel coating film forming. The method includes a multi-pattern coating film forming step in which the coating film for forming a multi-colored pattern described in any of the above is applied to the surface of the enamel coating film formed in the film step to form a film. Can be done.

By this film forming method, cracks and dirt on the outer wall of the siding can be concealed, and ultraviolet rays and the like can be prevented from being transmitted to the substrate. In addition, it can be applied neatly using an inexpensive wool roller or the like.
At this time, it is preferable that the micro-colored flakes have a color tone close to the color of the underlying enamel coating film, and more preferably the same color tone as the enamel coating film.

More specifically, in the multi-pattern coating film forming process, a coating film of a color difference measuring paint in which micro-colored flakes and a clear paint contained in the multi-pattern forming paint are mixed at a solid content ratio of 100:39 and enamel. It is preferable to use a coating film for forming a multicolored pattern, which uses a coating film for forming a multicolored pattern and a color difference ΔE of 5.0 or less with the coating film of the enamel paint used in the coating film forming step.

The above problem is also solved by a coated article in which a multicolored pattern coating film is formed on the surface of the enamel coating film by the paint for forming a multicolored pattern according to any one of the above.

As a method for producing a paint for forming a multicolored pattern, an emulsion resin solution, micro-colored flakes passing through a sieve having an opening size of 200 μm, and a sieve having an opening size of 2.8 mm and passing through a sieve having an opening size of 212 μm are passed. It is provided with a paint-making process in which macro-colored flakes of a plurality of colors are mixed and made into a paint. In the paint-making step, micro-colored flakes are blended in a paint so as to be 2 to 20% by weight. We propose a method for manufacturing paints for pattern formation. Here, the macro-colored flakes of the plurality of colors may contain colored flakes having the same color tone as the micro-colored flakes.

At this time, as macro-colored flakes of a plurality of colors, small-diameter colored flakes that pass through a sieve having an opening size of 600 μm and do not pass through a sieve having an opening size of 212 μm, and small-diameter colored flakes that pass through a sieve having an opening size of 1.4 mm and have an opening size of 1.4 mm. Manufacture of paint for forming various patterns using medium-diameter colored flakes that do not pass through a 212 μm sieve and large-diameter colored flakes that pass through a sieve with a mesh size of 2.8 mm and do not pass through a sieve with a mesh size of 600 μm. It is preferable to use the method.

At this time, in the paint-making step, the small-diameter colored flakes are 1 to 15% by weight in the paint, the medium-diameter colored flakes are 0.1 to 10% by weight in the paint, and the large-diameter colored flakes are 0.1 to 5% by weight in the paint. It is preferable to use a method for producing a paint for forming a multicolored pattern, which is blended so as to be% by weight.

INDUSTRIAL APPLICABILITY According to the present invention, it is possible to provide a coating material for forming a multicolored pattern, which can be easily applied using an inexpensive wool roller or a brush and has less uneven coating (less noticeable), a method for forming a coating material for forming a multicolored pattern, and the like. Can be done.

Hereinafter, embodiments of the present invention will be illustrated and described. The paint for forming a multicolored pattern includes micro-colored flakes and macro-colored flakes.
The present invention is not limited to the following embodiments.

1. 1. Micro-colored flakes Micro-colored flakes are colored flakes having a size that allows them to pass through a sieve having an opening size of 200 μm. Micro-colored flakes can be obtained by sieving the colored flakes. The colored flakes are colored flake-like powders containing a resin as a main component. Such colored flakes can be obtained, for example, by thinly applying a liquid raw material to a peelable base material or the like, drying the liquid raw material, peeling off the base material or the like, and pulverizing the liquid raw material. Hereinafter, a method for producing colored flakes will be described as an example.

First of all, the liquid raw material that is the source of the colored flakes is prepared. As the liquid raw material, a material containing a synthetic resin or synthetic resin emulsion as a binder, a coloring pigment as a coloring component, or the like can be used. In addition to this, extender pigments, aggregates, thickeners, leveling agents and the like may be included.

Synthetic resins or synthetic resin emulsions include known synthetic resins such as acrylic resin, ethylene-acrylic resin, vinyl acetate-acrylic resin, styrene-acrylic resin, urethane resin, silicon resin, urethane-acrylic resin, and silicon-acrylic resin. , Chloroprene latex, acrylic butadiene latex and other rubber latex can be used. Above all, it is preferable to use an acrylic silicone resin from the viewpoint of weather resistance. For example, acrylic silicone resin and ceramic modified acrylic silicone resin are suitable. Examples of the acrylic silicone resin include "Polydurex H-7650" manufactured by Asahi Kasei Corporation.

As the coloring pigment, for example, titanium oxide, yellow iron oxide, red iron oxide (ferric oxide: red iron oxide), phthalocyanine blue, ocher, ultramarine, carbon black, black iron oxide and the like can be used. As the extender pigment, for example, calcium carbonate, clay, talc, kaolin, bentonite, silica stone powder, diatomaceous earth, white carbon and the like can be used.

Aggregates include fine particles such as silica sand at the time of production, for example, crushed natural stones such as cold water stone, granite, and marble into fine particles, as well as glass beads, plastic beads, cold water sand, and silica sand. As the core, one coated with paint or one coated with glaze can be used.

As a method for producing colored flakes, for example, a liquid raw material is applied onto a flat, peelable substrate by a coating means (for example, a film applicator: JIS-K5101) capable of ensuring a constant film thickness and dried. After that, it is conceivable to peel off from the base material and pulverize by a pulverizing means.

The colored flakes thus obtained are sieved with a mesh size of 200 μm, and those passed through the sieve can be used as micro colored flakes.

The micro-colored flakes may be composed of monochromatic colored flakes. For example, white colored flakes alone, gray (N-70) colored flakes alone, black colored flakes alone, and so on.

The color of the micro-colored flakes is preferably close to the color of the base (the surface on which the paint for forming a multicolored pattern is applied), and more preferably the same color as the base.
When an enamel coating is used as a base, specifically, a coating of a color difference measuring paint in which micro-colored flakes and a clear paint contained in a paint for forming a multicolored pattern are mixed in a predetermined ratio, and a coating of an enamel paint. And, the color difference ΔE is preferably 5.0 or less. Hereinafter, the method for measuring the color difference ΔE will be described in detail.

The paint for measuring a color difference is obtained by mixing a clear paint and micro-colored flakes in a ratio of clear paint resin solid content: micro-colored flakes in a weight ratio of 39: 100. As the resin of the clear paint, it is preferable to use an acrylic silicone resin (for example, "Polydurex H-7650" manufactured by Asahi Kasei Corporation). Then, the obtained color difference measuring paint is applied to white cardboard with a coating thickness setting of 40 mil using an applicator and dried to obtain a coating film of the color difference measuring paint.
On the other hand, the enamel paint used as the base is applied to white cardboard with a coating thickness setting of 10 mil using an applicator and dried to obtain a coating film of the enamel paint.
The color difference ΔE between the coating film of the paint for measuring the color difference and the coating film of the enamel paint is measured using a color difference meter (CR-400 manufactured by Konica Minolta).
From the viewpoint of reducing coating unevenness, the color difference ΔE is preferably 5.0 or less, more preferably the color difference ΔE4.0 or less, and most preferably the color difference ΔE3.0 or less.

2. Macro colored flakes
The macro-colored flakes are colored flakes having a size that passes through a sieve having a mesh size of 2.8 mm and does not pass through a sieve having a mesh size of 212 μm. Macro-colored flakes of a plurality of colors are used in the paint for forming a multicolored pattern of the present invention.

Specifically, the above-mentioned colored flakes are passed through a sieve having an opening size of 2.8 mm, and those that have passed through the sieve are further passed through a sieve having an opening size of 212 μm and remain on a sieve having an opening size of 212 μm (opening). Those that have not passed through a sieve having a size of 212 μm) can be used as macro-colored flakes. A plurality of colors of such macro-colored flakes can be prepared, and for example, each of them can be mixed at a predetermined ratio and blended into the paint.

For example, three-color macro-colored flakes of white macro-colored flakes, gray (N-70) macro-colored flakes, and black macro-colored flakes can be prepared and blended in the paint.
One of the macro-colored flakes of a plurality of colors can have the same color tone as the micro-colored flakes. For example, if the micro-colored flakes are gray (N-70), gray (N-70) having the same color tone can be used for one of the plurality of macro-colored flakes.

Further, the macro-colored flakes can be separated into small-diameter colored flakes, medium-diameter colored flakes, and large-diameter colored flakes by a sieve, and the particle size of each and the blending ratio in the paint can be controlled.

For example, those that pass through a sieve with a mesh size of 600 μm and do not pass through a sieve with a mesh size of 212 μm are small-diameter colored flakes, and those that pass through a sieve with a mesh size of 1.4 mm and do not pass through a sieve with a mesh size of 212 μm. Large-diameter colored flakes can be defined as medium-diameter colored flakes that pass through a sieve having a mesh size of 2.8 mm and do not pass through a sieve having a mesh size of 600 μm.

The small-diameter colored flakes, the medium-diameter colored flakes, and the large-diameter colored flakes are preferably composed of a plurality of colored flakes, and one of them can be a colored flakes having the same color tone as the micro-colored flakes. For example, if the micro-colored flakes are gray (N-70), each of the small-diameter colored flakes, the medium-diameter colored flakes, and the large-diameter colored flakes contains gray (N-70) colored flakes having the same color tone. You may be.

3. 3. Method for Producing Paint for Forming Multicolored Patterns A paint for forming multicolored patterns is manufactured using the micro-colored flakes and the macro-colored flakes of a plurality of colors. Specifically, in the paint-making step, the emulsion resin solution, the micro-colored flakes, and the macro-colored flakes of a plurality of colors are mixed and dispersed at a predetermined ratio to make a paint. Regarding the macro-colored flakes, a mixture of a plurality of colors of macro-colored flakes at a predetermined ratio may be prepared in advance.

As the micro-colored flakes, those that pass through a sieve having an opening size of 200 μm are used. At this time, the blending amount of the micro-colored flakes is 2 to 20% by weight in the paint. If the blending amount of the micro-colored flakes is less than 2% by weight in the paint, coating unevenness is likely to occur during roller coating. Further, if the blending amount of the micro-colored flakes exceeds 20% by weight in the paint, it becomes difficult to obtain a multicolored feeling of the coating film. The blending amount of the micro-colored flakes is preferably 3 to 18% by weight in the coating material, and more preferably 4 to 16% by weight in the coating material.

The blending amount of the macro-colored flakes of a plurality of colors is preferably 1 to 15% by weight in the paint. If the blending amount of the macro-colored flakes of a plurality of colors is less than 1% by weight in the paint, it becomes difficult to obtain a multicolored feeling of the coating film. Further, if the blending amount of the macro-colored flakes of a plurality of colors exceeds 15% by weight in the paint, the workability is deteriorated and coating unevenness at the time of roller coating is likely to occur. The blending amount of the macro-colored flakes of the plurality of colors is preferably 1.5 to 14% by weight in the paint, and more preferably 1.9 to 12% by weight in the paint.

As described above, when the macro-colored flakes of multiple colors are separated into small-diameter colored flakes, medium-diameter colored flakes, and large-diameter colored flakes, the small-diameter colored flakes are added to the paint by 1 to 15% by weight, and the medium-diameter colored flakes are applied to the paint. It is preferable to mix 0.1 to 10% by weight in the paint and 0.1 to 5% by weight in the paint, respectively. More preferably, the small diameter colored flakes are 1 to 10% by weight in the paint, the medium diameter colored flakes are 0.1 to 5% by weight in the paint, and the large diameter colored flakes are 0.1 to 3% by weight in the paint. It is to mix each so that it becomes. A mixture of small-diameter colored flakes, medium-diameter colored flakes, and large-diameter colored flakes at a predetermined ratio may be prepared in advance.

In addition to micro-colored flakes and macro-colored flakes of a plurality of colors, various fillers such as colored beads and mica may be added to the paint for forming a multicolored pattern as long as the weather resistance and workability are not significantly impaired. .. Further, a matting agent such as silica or acrylic beads, or various additives such as a leveling agent or a dispersant may be added.

4. Method of forming a coating film for forming a multicolored pattern As a method of forming a film of a paint for forming a multicolored pattern thus obtained, it is possible to directly coat the surface to be coated, but it is formed by applying a base coating. It is preferable to apply it on the surface of the filmed base coating film. At this time, it is preferable to apply a paint for forming a multicolored pattern using micro-colored flakes having a color tone (including the same color tone as that of the base) close to the color of the base (the surface to be coated or the base coating film).
Specifically, as described above, when an enamel coating is used as a base, a coating of a paint for measuring color difference, which is a mixture of micro-colored flakes contained in a paint for forming a multicolored pattern and a clear paint in a predetermined ratio, and a coating of a paint for measuring a color difference, It is preferable that the color difference ΔE between the coating film of the enamel paint and the coating film is 5.0 or less.

As a method for forming a paint for forming a multicolored pattern, for example, an enamel coating film forming step of applying an enamel paint to the surface of a surface to be coated such as an outer wall to form a film, and a film forming step of this enamel coating film forming step. It is preferable to use a method for forming a paint for forming a multicolored pattern, which comprises a step of forming a multicolored pattern coating film by applying a paint for forming a multicolored pattern on the surface of the enamel coating film. .. The enamel coating film serves as a base coating film.
The enamel coating applied to the surface of the surface to be coated hides defects such as dirt and cracks on the surface to be coated and secures the shielding effect of ultraviolet rays, etc., and is applied to the surface of the enamel coating film for forming various patterns. The paint ensures a high degree of design. The paint for forming a multicolored pattern can be applied using an inexpensive wool roller or brush, and also has the effect of having less uneven coating (less noticeable).

Next, the present invention will be specifically described with reference to Examples, but the present invention is not limited thereto. In the examples, the quantity ratio and the like are values based on weight.

1. Preparation of colored flakes Based on the formulation table in Table 1 below, liquid raw materials to be colored flakes were prepared. In this example, in order to prepare colored flakes of three colors of white, gray (N-70), and black, three kinds of liquid raw materials were also prepared.

Each of the obtained three types of liquid raw materials was applied onto a Teflon (registered trademark) sheet with a film thickness setting of 10 mil using a film applicator, and dried to form a film. The obtained dry coating film was peeled off from a Teflon (registered trademark) sheet and finely pulverized using a pulverizer to obtain three-color (white, gray (N-70), black) colored flakes.

The micro-colored flakes were obtained by subjecting gray (N-70) colored flakes to a sieve having an opening size of 100 μm and passing through the sieve.

Regarding macro-colored flakes (small-diameter colored flakes, medium-diameter colored flakes, and large-diameter colored flakes), each of the three colored flakes passes through a sieve having an opening size of 600 μm and does not pass through a sieve having an opening size of 212 μm. For small diameter colored flakes, those that pass through a sieve with a mesh size of 1.4 mm and do not pass through a sieve with a mesh size of 212 μm are for medium diameter colored flakes, pass through a sieve with a mesh size of 2.8 mm and have a mesh size. Those that did not pass through a sieve having a size of 600 μm were used for large-diameter colored flakes. As shown in the formulation table of Table 3, the three colors for small-diameter colored flakes are mixed or blended in a predetermined ratio, the small-diameter colored flakes are mixed or blended, and the three colors for medium-diameter colored flakes are mixed or blended in a predetermined ratio. Large-diameter colored flakes were obtained by mixing or blending three colors for diameter-colored flakes and large-diameter colored flakes at a predetermined ratio.

2. Preparation of resin solution Table 2 below shows the formulation of the emulsion resin solution (clear paint A) used for the paint for forming various patterns. Except that an acrylic silicone resin is used as the emulsion resin, the composition is the same as that of a general clear paint.

3. Manufacture of paint for forming colorful patterns Using the above emulsion resin solution (clear paint A), micro-colored flakes, and multi-colored macro-colored flakes (small-diameter colored flakes, medium-diameter colored flakes, large-diameter colored flakes), It was made into a paint with the formulation shown in Table 3 below. The multi-colored macro-colored flakes partially contain colored flakes (gray: N-70) having the same color tone as the micro-colored flakes. Specifically, each of the small-diameter colored flakes, the medium-diameter colored flakes, and the large-diameter colored flakes constituting the macro-colored flakes of multiple colors partially contains colored flakes (gray: N-70) having the same color tone as the micro-colored flakes. Includes.

For the paint for forming various patterns in each example and comparative example, a normal enamel paint (gray: N-70) is applied to form a film, and then spray coating, sand bone roller coating, and wool roller coating are applied to the surface thereof. We evaluated workability, uneven coating, and multicolored feeling. The coating unevenness and the multicolored feeling were evaluated by visually confirming with 5 to 10 people at a distance of 3 to 5 m from the painted object after painting.

Specifically, the case where 80% or more of the evaluators are judged to be good is ○, the case where 50% or more and less than 80% is judged to be good is △, and the case where 20% or more and less than 50% is judged to be good is △ ~ X was evaluated as x when less than 20% was judged to be good.

For each Example and each Comparative Example, micro-colored flakes (gray) and clear paint contained in the paint for forming a multicolored pattern were blended at a solid content ratio of 100:39 (micro-colored flakes (gray) and solid content 39%). The color difference ΔE between the coating film of the paint for measuring the color difference and the coating film of the enamel paint (gray: N-70) was 5.0 or less.

In Examples 1 to 3, very good results were obtained in all of workability, coating unevenness and multicolored feeling in all of spray coating, sand bone roller coating and wool roller coating.

In Comparative Example 1, since the amount of micro-colored flakes was as small as 1.0%, coating unevenness was likely to occur in sand bone roller coating and wool roller coating.
Further, in Comparative Example 2, since the macro-colored flakes were not blended, it was difficult to obtain a multicolored feeling.
Further, in Comparative Example 3, since the micro-colored flakes were not blended, the workability was poor and coating unevenness was likely to occur in the sand bone roller coating and the wool roller coating.
In addition, in Comparative Example 4, since the micro-colored flakes were not blended and only the small-diameter colored flakes were blended as the macro-colored flakes, it was difficult to obtain a multicolored feeling.

Although the present invention has been described above with reference to specific embodiments and examples, the present invention is not limited to the above-described embodiments and the like, and is attached to the application of the present application by an expert or the like in the technical field. Various changes and amendments can be made without departing from the scope of the claims made.
