Description

The present invention relates to irregularly shaped colored gel particles, a method for producing irregularly shaped colored gel particles, a paint containing irregularly shaped colored gel particles, and a method for producing a paint containing irregularly shaped colored gel particles. In particular, the present invention relates to irregularly shaped colored gel particles having a fibrous substance, a method for producing the irregularly shaped colored gel particles, a paint containing the irregularly shaped colored gel particles, and a method for producing a paint containing the irregularly shaped colored gel particles.

In recent years, paints containing colored gel particles, such as multicolored paints, have come to be used more frequently as finishing materials for the exteriors (e.g., walls and roofs) and interiors of buildings.

Here, multicolor paint is a paint in which gel-like particles of two or more colors (colored gel particles of two or more colors) are suspended, and has the characteristic that a color-scattered pattern can be created with a single coat of paint (JIS K 5667). Conventionally, the colored gel particles used in multicolor paint are composed of a resin emulsion, a pigment, and a hydrogel. Such multicolor paint is described, for example, in Patent Document 1 below.

Patent Document 1 describes "colored polymer granules that can be obtained by dropping a thermosensitive gelling emulsion composition containing (i) an aqueous synthetic resin emulsion, (ii) a thermosensitive gelling agent, and (iii) a colorant into water having a temperature equal to or higher than the gelling temperature of the composition, thereby causing gelation," and goes on to say that this makes it possible to "provide an aqueous multicolored pattern paint composition that is suitable for various painting methods such as spray, roller, and brush."

JP 2003-041196 A

However, most of the colored gel particles used in such multicolored paints are roughly spherical, so the shape of the colored gel particles (dried matter) that appear on the surface of the coating film is circular or elliptical, resulting in a monotonous design with little variation.

In particular, in recent years, there has been an increasing demand for highly decorative exteriors (e.g., walls and roofs) and interiors of buildings, and there has been a strong demand for paints that can realize innovative designs not available in conventional multi-colored paints.

The present invention has been made with the above in mind, and aims to provide irregularly shaped colored gel particles that can realize novel designs not found in conventional multicolored paints, a method for producing irregularly shaped colored gel particles, paint containing irregularly shaped colored gel particles, and a method for producing paint containing irregularly shaped colored gel particles.

In order to solve the above problems, irregularly shaped colored gel particles are provided, which contain a fibrous material, a synthetic resin emulsion, a color pigment, and a hydrogel.
Here, the irregularly shaped colored gel particles include colored gel particles that are not perfectly circular, elliptical or discoid, as well as particles having protrusions due to fibrous substances.

These irregularly shaped colored gel particles have a novel shape that is not found in conventional colored gel particles due to the fibrous material, and when used in multicolored paints, they can realize innovative designs that have not been seen before.

Irregularly shaped colored gel particles can be produced that contain 1 to 30 parts by weight of fibrous material per 100 parts by weight of the solid content of the synthetic resin emulsion.

These irregularly shaped colored gel particles have a more innovative shape than conventional colored gel particles due to the specific amount of fibrous material.

The fibrous material can also be irregularly shaped colored gel particles with a length of 1 to 20 mm.

These irregularly shaped colored gel particles have a more innovative shape than conventional colored gel particles, due to the specific length of the fibrous material.

It is also possible to produce irregularly shaped colored gel particles in which some or all of the fibrous material is bundled.

These irregularly shaped colored gel particles have a more innovative shape than conventional colored gel particles due to the bundled fibrous material.

The irregularly shaped colored gel particles may be made of inorganic fibers as fibrous materials, or may be made of glass fibers as fibrous materials.

These irregularly shaped colored gel particles are made from a specific fibrous material, giving them a more innovative shape than conventional colored gel particles.

The fibrous material can also be made into irregularly shaped colored gel particles with a single fiber diameter (filament diameter) of 1 to 100 μm.

These irregularly shaped colored gel particles are made of fibrous material with a specific single fiber diameter, giving them a more innovative shape than conventional colored gel particles.

As a method for producing irregularly shaped colored gel particles, there can be mentioned a method in which an irregularly shaped colored gel raw material composition containing a fibrous material, a synthetic resin emulsion, a color pigment, and a hydrogel component is added to an aqueous medium containing a hydrogel insolubilizer, and the hydrogel component is reacted with the hydrogel insolubilizer to generate a hydrogel, thereby obtaining irregularly shaped colored gel particles consisting of the fibrous material, the synthetic resin emulsion, the color pigment, and the hydrogel.

The above problem is also solved by a paint containing irregularly shaped colored gel particles, which contains any of the irregularly shaped colored gel particles described above.

This paint uses irregularly shaped colored gel particles (including fibrous materials) to create unprecedented and innovative designs.

In this case, it is preferable to use a paint containing irregularly shaped colored gel particles, which contains irregularly shaped colored gel particles and colored gel particles that do not contain fibrous material.

This paint uses irregularly shaped colored gel particles (containing fibrous material) in combination with colored gel particles that do not contain fibrous material, allowing the fibrous design effect provided by the irregularly shaped colored gel particles to be adjusted. The irregularly shaped colored gel particles (containing fibrous material) and the colored gel particles that do not contain fibrous material may be roughly the same color tone or different color tones.

The method for producing a paint containing irregularly shaped colored gel particles can be a method for producing a paint containing irregularly shaped colored gel particles and colored gel particles that do not contain fibrous substances, and can include a design adjustment blending step in which the irregularly shaped colored gel particles and colored gel particles that do not contain fibrous substances are blended in a predetermined ratio so that the fibrous design of the irregularly shaped colored gel particles after the paint film is formed will have the desired design.

The present invention provides irregularly shaped colored gel particles that can realize novel designs not found in conventional multicolored paints, a method for producing irregularly shaped colored gel particles, paint containing irregularly shaped colored gel particles, and a method for producing paint containing irregularly shaped colored gel particles.

Hereinafter, irregularly shaped colored gel particles, a method for producing irregularly shaped colored gel particles, a paint containing irregularly shaped colored gel particles, and a method for producing a paint containing irregularly shaped colored gel particles will be described by way of example.
The irregularly shaped colored gel particles include a fibrous material, a synthetic resin emulsion, a color pigment, and a hydrogel.

Below, we will explain examples of irregularly shaped colored gel particles, but the present invention is not limited to the following embodiments.

[Fibrous material]
The fibrous material is an essential component of the irregularly shaped colored gel particles.

As the fibrous material, for example, inorganic fibers or organic fibers can be used. Here, "fibrous material" refers to a material having a shape with an aspect ratio of 20 or more. The aspect ratio of a fibrous material is calculated as the ratio of the length to the single fiber diameter based on the single fiber diameter and length of the fibrous material. The method for measuring the single fiber diameter and length of a fibrous material will be described later. The aspect ratio of a fibrous material is preferably 50 or more, more preferably 100 or more, even more preferably 200 or more, and most preferably 300 or more. The aspect ratio of a fibrous material may be 400 or more.

Examples of inorganic fibers include rock wool, glass wool, glass fiber, silica fiber, alumina fiber, silica-alumina composite oxide fiber, carbon fiber, silicon carbide fiber, etc.

Examples of organic fibers include polymer fibers such as polyester fibers, wood fibers, and cellulose fibers.

For irregularly shaped colored gel particles, it is preferable to use inorganic fibers as the fibrous material from the standpoint of weather resistance. Among these, it is preferable to use glass fibers.

It is preferable that the fibrous material is partially or entirely in bundle form (chopped strand form).

The length of the fibrous material is preferably 1 to 20 mm, more preferably 3 to 15 mm, even more preferably 4 to 10 mm, and most preferably 5 to 7 mm. When the fibrous material is in a bundle (chopped strand) form, the length of the fibrous material is measured according to JIS R3420:2013 General test method for glass fibers, 7.8 Chopped strand length.

The single fiber diameter (filament diameter) of the fibrous material is preferably 1 to 100 μm, more preferably 2 to 50 μm, even more preferably 3 to 20 μm, and most preferably 5 to 15 μm. The single fiber diameter is measured according to JIS R3420:2013 General test method for glass fibers, 7.6 Single fiber diameter.

The content of the fibrous material in the irregularly shaped colored gel particles is preferably 1 to 30 parts by weight, more preferably 3 to 15 parts by weight, even more preferably 4 to 10 parts by weight, and most preferably 5 to 6 parts by weight, per 100 parts by weight of the solid content of the synthetic resin emulsion described below.

[Synthetic resin emulsion]
The synthetic resin emulsion is an essential component of the irregularly shaped colored gel particles, and is a dispersion of synthetic resin particles emulsified in water or a water-containing solvent.

The resin component of the synthetic resin emulsion is not particularly limited. For example, known synthetic resins such as acrylic resin, ethylene-acrylic resin, vinyl acetate-acrylic resin, styrene-acrylic resin, urethane resin, silicone resin, urethane-acrylic resin, and silicone-acrylic resin can be used. Among them, from the viewpoint of weather resistance, it is preferable to use acrylic resin, and in particular acrylic silicone resin. For example, acrylic silicone resin and ceramic modified acrylic silicone resin are suitable.

An example of an acrylic silicone resin emulsion is "Polydurex B3220" manufactured by Asahi Kasei Corporation.

[Coloring pigment]
The color pigment is an essential component of the irregular colored gel particles. For example, titanium oxide, yellow iron oxide, red iron oxide (ferric oxide: red iron oxide), phthalocyanine blue, ocher, ultramarine, carbon black, etc. can be used as the color pigment, but it is not limited thereto. When making white irregular colored gel particles, it is considered that titanium oxide is often used as a white pigment.

The content of the color pigment in the irregularly shaped colored gel particles is preferably 30 to 300 parts by weight, more preferably 50 to 250 parts by weight, and most preferably 100 to 200 parts by weight, per 100 parts by weight of the solid content of the synthetic resin emulsion.

[Hydrogel]
Hydrogel is an essential component of irregularly shaped colored gel particles. Hydrogel has a structure in which water is held in a hydrogel-forming substance to form a gel. The hydrogel-forming substance is a compound that forms a network structure to hold the water in the gel and exerts a gelling effect, and is formed by reaction or bonding between a hydrogel constituent material (main hydrogel raw material) that is the main part of the network structure and a hydrogel insolubilizer (gelling agent) that is the joint part of the network structure.

The hydrogel constituent material (main hydrogel raw material) is not particularly limited as long as it can form a hydrogel, and may be an organic compound or an inorganic compound, or a mixture of both.

As the organic compound, a hydroxyl group-containing organic polymer is preferred. For example, polyvinyl alcohol, guar gum, carrageenan, xanthan gum, methyl cellulose, hydroxymethyl cellulose, and derivatives thereof can be used. Among them, polyvinyl alcohol, guar gum, and guar gum derivatives (modified by hydroxypropylation, etc.) are preferred, since they allow the resin to be well dispersed and provide a hydrogel with excellent stability.

As the inorganic compound, a water-swellable silicate compound is preferred. For example, water-swellable clay minerals such as hectorite, montmorillonite, bentonite, and attapulgite can be used. These water-swellable silicate compounds may be natural minerals as well as synthetic compounds. Among them, synthetic hectorite is preferred because it gives a hydrogel with excellent stability.

As the hydrogel insolubilizer (gelling agent) that reacts or bonds with the hydrogel constituent material to become the joint part of the network structure, phosphate, borate, silicate, etc. can be used. Phosphate and borate are preferred in that they can form a good hydrogel that is difficult to dissolve in water. When the hydrogel constituent material is a water-swellable silicate compound such as hectorite, phosphate is particularly preferred, and when the hydrogel constituent material is a hydroxyl group-containing organic polymer such as polyvinyl alcohol or guar gum, borate is particularly preferred. This is because they can form a stable hydrogel in water.
Examples of the phosphate that can be used include sodium phosphates such as sodium pyrophosphate, potassium phosphates such as potassium pyrophosphate, and the like. Examples of the borates that can be used include ammonium borates such as ammonium pentaborate, and borax.

When a hydrogel component (main hydrogel ingredient) and a hydrogel insolubilizer (gelling agent) react or bond to form a network structure with a hydrogel-forming substance, the two may simply be bonded additively, such as by addition, or may be bonded by condensation, such as by dehydration, in which some of their atoms are detached and bonded.

The hydrogel has been described as having a network structure made of hydrogel constituent materials and a hydrogel insolubilizer (gelling agent), but the hydrogel may be formed by a different mechanism than the formation of the network structure.

[Method of manufacturing irregularly shaped colored gel particles]
Next, a method for producing irregularly shaped colored gel particles will be illustrated.

The irregularly shaped colored gel particles can be obtained, for example, by adding an irregularly shaped colored gel raw material composition containing a fibrous substance, a synthetic resin emulsion, a color pigment, and a hydrogel component to an aqueous medium containing a hydrogel insolubilizer (gelling agent), and causing the hydrogel component and the hydrogel insolubilizer to react with each other to produce a hydrogel-forming substance (hydrogel).
In other words, the irregularly shaped colored gel particles are formed by integrating a fibrous substance with colored gel particles (conventional colored gel particles) containing a synthetic resin emulsion, a color pigment, and a hydrogel.

First, the fibrous material, synthetic resin emulsion, color pigment, hydrogel constituent material, and optional components such as water solvent, extender pigment, preservative, thickener, and various additives are added and stirred until uniformly dispersed to prepare the irregular colored gel raw material composition.

The content of the synthetic resin emulsion in the irregular colored gel raw material composition is preferably 1 to 30% by weight, more preferably 2 to 20% by weight, even more preferably 3 to 15% by weight, and most preferably 4 to 10% by weight, based on the synthetic resin solids content.

The content of the color pigment in the irregular colored gel raw material composition is preferably 1 to 30% by weight, more preferably 3 to 20% by weight, even more preferably 4 to 15% by weight, and most preferably 5 to 10% by weight.

The content of the hydrogel constituent material in the irregular colored gel raw material composition is preferably 10 to 100 parts by weight in terms of solid content, more preferably 20 to 80 parts by weight in terms of solid content, even more preferably 25 to 50 parts by weight, and most preferably 30 to 40 parts by weight in terms of solid content, relative to 100 parts by weight of the solid content of the synthetic resin emulsion.

The size of the irregularly shaped colored particles (the particles before gelation) varies depending on the time for which the irregularly shaped colored gel raw material composition is stirred, so it is preferable to stir the irregularly shaped colored particles to a size of about 1 to 20 mm. The size of the irregularly shaped colored particles is more preferably 2 to 10 mm, and even more preferably 3 to 8 mm.

Next, the obtained irregular colored gel raw material composition (containing the irregular colored particles) is added to an aqueous solution containing a hydrogel insolubilizer (gelling agent). At this time, it is preferable to gradually add the irregular colored gel raw material composition while stirring the aqueous solution containing the hydrogel insolubilizer (gelling agent), and continue stirring for a while after that.

The concentration of the hydrogel insolubilizer (gelling agent) in the aqueous solution is preferably 0.01 to 1.0% by weight, more preferably 0.05 to 0.5% by weight, even more preferably 0.1 to 0.4% by weight, and most preferably 0.2 to 0.3% by weight.

After the stirring is completed, it is desirable to leave the mixture at rest for at least 1 hour, preferably at least 5 hours, at room temperature in order to form a stable gel. The upper limit of the standing time is usually about 24 hours, since the gel thus formed reaches an equilibrium state.
By the above-mentioned production method, a gel-forming substance having a network structure or the like is formed, and the water in which the resin or the like is dispersed is held in the network structure or the like, thereby obtaining irregularly shaped colored gel particles.

[Paint containing irregularly shaped colored gel particles]
The irregularly shaped colored gel particles thus obtained can be used, for example, in paints, and can realize coating films with unprecedented and novel designs.

There are no particular limitations on the paint containing irregularly shaped colored gel particles. For example, in a conventional paint containing colored gel particles (such as a multicolored paint), some or all of the colored gel particles can be replaced with irregularly shaped colored gel particles.

Specifically, the paint can contain irregularly shaped colored gel particles and a synthetic resin emulsion. If desired, the paint can also contain optional components such as color pigments, extender pigments, preservatives, thickeners, various additives, and water solvents.

Paint containing irregularly shaped colored gel particles can contain, for example, not only irregularly shaped colored gel particles (containing fibrous material), but also colored gel particles that do not contain fibrous material. By using irregularly shaped colored gel particles in combination with conventional colored gel particles, it is possible to adjust the fibrous design feel.

The surface to be coated with the coating material containing the irregular colored gel particles is not particularly limited. For example, the coating material can be applied to the exterior and interior walls of buildings. The material of the surface to be coated is also not particularly limited. For example, porcelain, tiles, concrete, ALC panels, mortar, siding boards, extrusion molding boards, gypsum boards, and plastic boards can be used.
Moreover, the coating can be used not only on the surfaces of newly constructed buildings, but also when repainting the surfaces of existing buildings.

There is no particular limitation on the method for applying the paint containing irregularly shaped colored gel particles to the surface of the surface to be painted. For example, it can be applied by spray painting or roller painting.

[Method of manufacturing a paint containing irregularly shaped colored gel particles]
A method for producing a coating material containing irregularly shaped colored gel particles (containing fibrous material) and colored gel particles not containing fibrous material may include a design adjustment blending step.
The design adjustment blending step is a step of blending the irregularly shaped colored gel particles and the colored gel particles in a predetermined ratio so that the fibrous design of the irregularly shaped colored gel particles after the coating film is formed will have a desired design.

Increasing the proportion of irregularly shaped colored gel particles (containing fibrous material) gives a stronger fibrous design feel, whereas decreasing the proportion of irregularly shaped colored gel particles and increasing the proportion of colored gel particles that do not contain fibrous material weakens the fibrous design feel.

The present invention will be described in detail below with reference to examples, but the present invention is not limited to these. In the examples, the ratios and other amounts are based on weight.

1. Preparation of irregularly shaped colored gel particles (Example 1)
Irregular colored gel particles were prepared based on the formulation table of Example 1 in Table 1 below. First, a synthetic resin emulsion (Asahi Kasei Corporation's "Polydurex B3220") was mixed with glass fiber (Nitto Boseki Corporation's "Chopped Strand CS 6J-888S") as a fibrous material and a color pigment (Teika Corporation's "JR-603"), and then an extender pigment (Shiraishi Calcium Corporation's "Whiten 305") and tap water were added. Then, hydrogel constituent materials PVA resin solution (Kuraray Co., Ltd.'s "Evanol 71-30"), polysaccharide (DSP Gokyo Food & Chemical Co., Ltd.'s "Echo Gum SF" 1% aqueous solution) and silicate compound (BYK's "Laponite RD") were mixed and stirred to obtain an irregular colored gel raw material composition.
The obtained mixed and stirred solution (irregularly shaped colored gel raw material composition) was poured into an aqueous solution containing a hydrogel insolubilizer (0.2% ammonium borate) while stirring, and stirring was continued until the particles reached a size of approximately 5 to 10 mm, thereby insolubilizing the particles and obtaining irregularly shaped colored gel particles.

The irregularly shaped colored gel particles obtained had the shape shown in Figures 1 to 3, in which the fibrous material and the colored gel particles were integrated, and the colored gel particles were attached to the fibrous material. Figures 1 to 3 are photographs showing the irregularly shaped colored gel particles in an undried state, and were taken underwater after the irregularly shaped colored gel particles obtained were washed with water. These photographs also show very small colored gel particles that do not contain fibrous material. Figures 4 to 6 are photographs showing the irregularly shaped colored gel particles after drying, and were taken after drying on 5 mm graph paper.

(Example 2) (Example 3)
These are examples in which the amount of glass fiber, which is a fibrous material, was increased (from 3.5 to 10 or 30) based on the formulation of Example 1. In all of the examples, fibrous irregularly shaped colored gel particles were obtained, and the shapes were novel and not found in conventional colored gel particles.

Example 4
This is an example in which long fibers (6 mm to 13 mm) were used as the fibrous glass fiber based on the formulation of Example 1. In this example, fibrous irregular shaped colored gel particles were also obtained, and the shape was novel and not found in conventional colored gel particles.

Example 5
This is an example in which a carbon fiber having a fiber length of 6 mm (Tenax (registered trademark) chopped fiber manufactured by Teijin Limited) was used as the fibrous material based on the formulation of Example 1. In this example, fibrous irregularly shaped colored gel particles were also obtained, and the shape was novel and not found in conventional colored gel particles.

Example 6
This is an example in which polyester fibers (commercially available) with a fiber length of 10 mm were used as the fibrous material based on the formulation of Example 1. In this example, fibrous irregularly shaped colored gel particles were also obtained, and the shape was novel and not found in conventional colored gel particles.

(Example 7)
This is an example in which carbon fibers having a fiber length of 6 mm were further added to the composition of Example 1. In this example as well, fibrous irregular shaped colored gel particles were obtained, and the particles had a novel shape not found in conventional colored gel particles.

(Example 8)
This is an example in which the amount of glass fiber, a fibrous material, was significantly reduced (from 3.5 to 0.5) based on the formulation of Example 1. Although the fibrous feel was reduced, the colored gel particles had irregular shapes of approximately oval shapes, a shape not seen in conventional colored gel particles.

Example 9
This is an example in which the amount of glass fiber, a fibrous material, was significantly increased (3.5 to 50) based on the formulation of Example 1. Although the fibrous feel was reduced, agglomerated irregularly shaped colored gel particles were formed, resulting in a shape not seen in conventional colored gel particles.

Example 10
This is an example in which carbon fibers with a fiber length of 0.5 mm were used as the fibrous material based on the formulation of Example 1. Although the fibrous texture was reduced, irregularly shaped colored gel particles were obtained, which were shapes not found in conventional colored gel particles.

(Example 11)
This is an example in which carbon fibers with a fiber length of 25 mm were used as the fibrous material based on the formulation of Example 1. Irregularly shaped colored gel particles were obtained, which were shapes not found in conventional colored gel particles.

(Comparative Example 1)
These are conventional colored gel particles that do not contain fibrous materials. They are conventional colored gel particles with a circular or elliptical shape.

2. Preparation of paint containing irregularly shaped colored gel particles (Paint Example 1)
Using the irregularly shaped colored gel particles of Example 1, a paint was prepared based on the recipe for Paint Example 1 in Table 2 below. Note that the matting agent used was "Techpolymer MBX-20" manufactured by Sekisui Chemical Co., Ltd., and the synthetic resin emulsion used was "Polydurex B3220/Texanol mixture" manufactured by Asahi Kasei Corporation.

When the resulting paint was applied to the exterior walls of a building, a coating with an unprecedented, innovative design was created that had a fibrous texture similar to that of Japanese paper.

(Paint Example 2)
A paint was obtained by mixing the irregularly shaped colored gel particles of Examples 1, 2 and 6 in the ratios shown in Table 2. When the paint obtained was applied to the exterior wall of a building, a coating film with an unprecedented and novel design, which had a fibrous feel like Japanese paper, was obtained.

Paint Example 3
Paints were obtained by mixing the irregularly shaped colored gel particles of Examples 1 and 5 with the colored gel particles of Comparative Example 1 in the ratios shown in Table 2. When the resulting paints were applied to the exterior walls of buildings, a coating film with an unprecedented novel design, in which the texture of the fibers was adjusted, was obtained from Paint Example 1.

(Paint Example 4)
The irregularly shaped colored gel particles of Examples 1 and 10 and the colored gel particles of Comparative Example 1 were mixed in the ratios shown in Table 2 to obtain paints. When the obtained paints were applied to the exterior walls of buildings, paint Example 1 produced a coating film with an unprecedented and innovative design in which the texture of the fibers was adjusted.

(Paint Example 5)
A coating material was obtained by mixing the irregularly shaped colored gel particles of Example 10 and the colored gel particles of Comparative Example 1 in the ratio shown in Table 2. When the coating material was applied to the exterior wall of a building, a coating film with a novel design that had never been seen before was obtained, although it had little fibrous feel.

(Comparative Paint Example 1)
A paint was obtained by blending only the colored gel particles of Comparative Example 1. When the paint obtained was applied to the exterior wall of a building, a coating film with a design similar to that of a conventional paint was obtained without a fibrous feel.

The present invention has been described above with reference to specific embodiments and examples, but the present invention is not limited to the above-mentioned embodiments, and various changes and modifications can be made by those skilled in the art without departing from the scope of the claims attached to this application.
