Description

[Technical field]

[0001] The present invention relates to a hybrid colored gel particle aggregate, a colored gel particle mixture containing this hybrid colored gel particle aggregate, a paint such as a multicolored pattern paint containing this colored gel particle mixture, a wall panel coated with this paint, a wall structure using this wall panel, a building having this wall structure, and a method for producing the colored gel particle mixture.

[0002] 2. Description of the Related Art In recent years, paints containing colored gel particles, such as multicolored paints, have come to be used as finishing materials for the exterior (for example, walls and roofs) and interior of buildings.

[0003] Here, the multicolored 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 multicolored paints are composed of a resin (resin emulsion), a pigment, and a hydrogel. Such multicolored paints are described, for example, in Patent Document 1 below.

[0004] 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 paint composition that is suitable for various painting methods such as spray, roller, and brush."

[0005] [Patent Document 1] JP 2003-041196 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, the colored gel particles used in such paints, such as multicolored paints, are almost all colored and roughly spherical, so that the colored gel particles (dried matter) that appear on the surface of the coating film are monotonous and roughly spherical, resulting in a monotonous design with little variation.

[0007] In particular, in recent years, there has been an increasing demand for high design quality for the 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 with conventional multi-colored paints.

[0008] The present invention has been made in consideration of the above matters, and aims to provide a hybrid colored gel particle aggregate, a colored gel particle mixture, a paint, a multicolored pattern paint, a wall panel, a wall structure, a building, and a method for manufacturing a colored gel particle mixture, which are capable of realizing novel designs not available in conventional paints. In particular, the present invention aims to provide a hybrid colored gel particle aggregate that is easy to express the bleeding feeling of natural stone material. [Means for solving the problem]

[0009] In order to solve the above problems, a hybrid colored gel particle aggregate is provided in which colored gel particles and colored solid particles are integrated together, and the colored solid particles are irregularly exposed from the colored gel particles. Specific embodiments are listed below.

[0010] (Aspect 1) A hybrid colored gel particle aggregate in which colored gel particles and colored solid particles are integrated together, and the colored solid particles are irregularly exposed from the colored gel particles (however, this does not include those in which the colored solid particles are fibrous materials). Here, the hybrid colored gel particles include one or more colored solid particles. The term "exposed" includes cases where a part or the whole of the colored solid particles are exposed, and also includes cases where colored gel particles are attached to part of the surface of the colored solid particles. Furthermore, the term "irregular exposure" refers to the fact that the colored solid particles are irregularly exposed from the colored gel particles when the hybrid colored gel particle aggregate is viewed as a whole. In addition, irregular exposure includes a case where there are irregularly transparent portions in addition to being irregularly exposed. In addition, cases where the exposure cannot be confirmed by visual inspection or where the exposure is excessive (for example, cases where there are only hybrid colored gel particles with almost no colored gel particles attached to the surface of the colored solid particles) are not included in the category of "irregularly exposed."

[0011] This hybrid colored gel particle aggregate allows the colored solid particles to be irregularly exposed from the colored gel particles, enabling the realization of novel designs not possible with conventional paints. Specifically, it makes it easier to express the blurring effect of natural stone. In addition, by excluding colored solid particles that are fibrous, it becomes easier to express the blurring effect of natural stone. Fibrous substances are substances that have a shape with an aspect ratio of 20 or more. It is preferable that the colored solid particles are not foamed, which makes it easier for the colored solid particles to be exposed from the colored gel particles of the hybrid colored gel particles.

[0012] (Aspect 2) The hybrid colored gel particle assembly according to aspect 1, wherein the colored solid particles are irregularly exposed from and irregularly transmitted through the hybrid colored gel particles.

[0013] This hybrid colored gel particle aggregate can realize even more innovative designs.

The true specific gravity of the colored solid particles is more preferably 0.5 to 2.6 g / cm 3 , and more preferably 1.0 to 2.0 g / cm 3 , and most preferably 1.2 to 1.5 g / cm 3 It is.

Here, the colored gel particles (first colored gel particles) constituting the hybrid colored gel particles have the same composition as the colored gel particles (second colored gel particles) constituting the plain colored gel particles, and 100 parts by weight of the colored gel particles is 100 parts by weight of the first colored gel particles and the second colored gel particles combined. The average particle size of the colored gel particle mixture is the overall average particle size of the hybrid colored gel particles and the plain colored gel particles contained in the colored gel particle mixture. Additionally, the hybrid colored gel particles include one or more colored solid particles. In addition, the term "exposed" includes cases where a part or all of the colored solid particles are exposed, and also includes an embodiment in which the colored gel particles are attached to part of the surface of the colored solid particles. In addition, irregular exposure includes a case where there are irregularly transparent portions in addition to being irregularly exposed. In addition, cases where the exposure cannot be confirmed by visual inspection or where the exposure is excessive (for example, where there are almost no colored gel particles attached to the surface of the colored solid particles) are not included in the category of "irregularly exposed."

[0021] This colored gel particle mixture allows the colored solid particles to be irregularly exposed from the colored gel particles of the hybrid colored gel particles, which allows for the realization of novel designs not possible with conventional paints. Specifically, it makes it easier to express the blurring effect of natural stone materials. In addition, by excluding colored solid particles that are fibrous, it becomes easier to express the blurring effect of natural stone.

[0023] This colored gel particle mixture makes it possible to realize even more innovative designs.

[Brief description of the drawings]

[0053] [Figure 1] 1 is a plan view of a colored gel particle mixture (using ground paint as the colored solid particles). [Diagram 2] This is a flat photograph of a colored gel particle mixture (using Cerven as the colored solid particles). [Diagram 3] 1 is a flowchart illustrating a method for producing a colored gel particle mixture. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0054] Hereinafter, the hybrid colored gel particle aggregate, the colored gel particle mixture, the paint, and the method for producing the colored gel particle mixture will be illustrated, but the present invention is not limited to the following embodiments.

[0055] Since the hybrid colored gel particle aggregate can be obtained as a colored gel particle mixture together with the plain colored gel particles, the colored gel particle mixture will first be illustrated and described, and then the hybrid colored gel particle aggregate will be illustrated and described.

[0056] 1. Colored gel particle mixture The colored gel particle mixture includes hybrid colored gel particles and plain colored gel particles. In detail, the colored gel particle mixture includes a plurality of hybrid colored gel particles (hybrid colored gel particle aggregates) and a plurality of plain colored gel particles (plain colored gel particle aggregates). Hereinafter, the hybrid colored gel particles and the plain colored gel particles constituting the colored gel particle mixture will be described by way of example.

[0057] (1) Hybrid colored gel particles The hybrid colored gel particles are an essential component of the colored gel particle mixture, and a plurality (a large number) of the hybrid colored gel particles are included in the colored gel particle mixture (hybrid colored gel particle aggregate). The hybrid colored gel particles are formed by integrating colored gel particles and colored solid particles. When the hybrid colored gel particle aggregate is viewed as a whole, the colored solid particles are irregularly exposed from the colored gel particles. The colored solid particles and colored gel particles constituting the hybrid colored gel particles will be illustrated below.

[0058] A. Colored solid particles The colored solid particles are colored solid particles.

[0059] As the colored solid particles, organic colored beads, inorganic colored beads, minerals and processed products thereof can be used. As the organic colored beads, color films, metal-deposited films, crushed coatings, and plastic beads can be exemplified. As the inorganic colored beads, glass beads and cerbenes can be exemplified. As the minerals and processed products thereof, gravel, barite, and mica can be exemplified. Note that the colored solid particles do not include extender pigments such as calcium carbonate.

[0060] Moreover, the colored solid particles do not include fibrous substances. By using colored solid particles (excluding fibrous substances), it becomes easier to realize the blurred look of natural stone when made into paint. A "fibrous substance" is, for example, a substance having a shape with an aspect ratio of 20 or more. The aspect ratio of a fibrous substance is calculated as the ratio of the length to the single fiber diameter based on the single fiber diameter and length of the fibrous substance. The colored solid particles may not include fibrous substances with an aspect ratio of 30 or more, 40 or more, or 50 or more. "Fibrous materials" include inorganic fibers and organic fibers. Examples of inorganic fibers include rock wool, glass wool, glass fibers, silica fibers, alumina fibers, silica-alumina composite oxide fibers, carbon fibers, silicon carbide fibers, etc., and examples of organic fibers include polymer fibers such as polyester fibers, wood fibers, cellulose fibers, etc.

[0061] It is preferable that the colored solid particles are not foam-shaped. Foam-shaped colored solid particles have small irregularities on the surface, and are therefore likely to be embedded in the colored gel particles or have the colored gel particles adhere to the entire surface, making them less likely to be exposed from the colored gel particles. In other words, by using colored solid particles (excluding foams), the colored solid particles are more likely to be irregularly exposed from the colored gel particles. The true specific gravity of the colored solid particles is 0.2 to 3.0 g / cm. 3 It is preferable that:

[0062] The coating pulverized material as the colored solid particles is a colored flake-like powder. The flake-like shape includes flat shapes such as plate-like and scale-like. The coating pulverized material preferably contains a resin and a pigment, and can be obtained, for example, by thinly applying a liquid raw material containing a resin and a pigment to a peelable substrate or the like, drying the liquid raw material, peeling it off from the substrate or the like, and pulverizing the liquid raw material. A method for producing pulverized coating material (colored flakes) will be described below by way of example.

[0063] First, a liquid raw material is prepared as the base for the coating powder. The liquid raw material may contain a synthetic resin, a solvent, a coloring pigment as a coloring component, etc. In addition, the liquid raw material may contain an extender pigment, an aggregate, a thickener, a leveling agent, etc.

[0064] As the synthetic resin, various synthetic resins and rubber latex can be used. Among them, it is preferable to use an acrylic silicone resin from the viewpoint of weather resistance. For example, an acrylic silicone resin and a ceramic modified acrylic silicone resin are preferable. As an acrylic silicone resin, for example, "U-DOUBLE EF-008" by Nippon Shokubai Co., Ltd. can be mentioned.

[0065] The synthetic resin can be used in the form of a resin emulsion in which the synthetic resin is dissolved in a solvent or dispersed in a solvent (particularly a water solvent).

[0066] Examples of color pigments that can be used include titanium oxide, yellow iron oxide, red iron oxide (ferric oxide: red iron oxide), phthalocyanine blue, ochre, ultramarine blue, carbon black, black iron oxide, etc. Examples of extender pigments that can be used include calcium carbonate, clay, talc, kaolin, bentonite, silica powder, diatomaceous earth, white carbon, etc.

[0067] As aggregates, materials that are fine when mined, such as silica sand, for example, natural stones such as kansui stone, granite, marble, etc., crushed into fine particles, as well as glass beads, plastic beads, kansui sand or silica sand cores coated with paint or glaze can be used.

[0068] As a method for producing the coated pulverized material, for example, a liquid raw material may be applied to a flat, peelable substrate using a coating means that can ensure a constant film thickness (for example, a film applicator: JIS-K5101) and then dried. In this case, it is preferable to apply the raw material to a thickness that results in a dry thickness of 150 μm or less. Most preferably, it is preferable to apply the raw material to a thickness that results in a dry thickness of 75 μm ± 15 μm. Thereafter, the coating film is peeled off from the substrate and pulverized by a pulverizing means to obtain a pulverized coating film.

[0069] The crushed coating film thus obtained is sieved through a sieve having a predetermined mesh size, and the material that passes through the sieve can be used.

[0070] The amount of the colored solid particles in the colored gel particle mixture is, as described below, 0.5 to 60 parts by weight per 100 parts by weight of the colored gel particles.

[0071] The average particle size of the colored solid particles is 0.2 to 5.0, whereas the average particle size of the colored gel particle mixture described below is 1. The average particle size of the colored gel particle mixture is the average particle size of a gel particle aggregate that combines hybrid colored gel particles and plain colored gel particles. In practice, as described below, in the raw material composition gelling step in the method for producing a colored gel particle mixture, the average particle size of the colored gel particle mixture is adjusted to be 0.2 to 5.0 when the average particle size of the colored solid particles is taken as 1. The average particle size of the colored solid particles is preferably 0.2 to 5.0 mm.

[0072] The "average particle size" of the average particle size of the colored solid particles is the 50% diameter of the weight cumulative particle size distribution, and the particle size distribution is measured using a laser diffraction particle size distribution measuring device (HRA Microtrack, manufactured by Nikkiso Co., Ltd.). The average particle size of the colored gel particle mixture will be described later.

[0073] As described below, the color of the colored solid particles is preferably such that the color difference ΔE between the hybrid colored gel particles and the colored gel particles is 3.0 or more. The color difference can be measured in a dried state of the hybrid colored gel particles.

[0074] B. Colored gel particles The colored gel particles are colored gel-like particles, and include a synthetic resin, a color pigment, and a hydrogel.

[0075] In detail, the colored gel particles can be obtained by adding a colored gel particle raw material composition containing a synthetic resin, a colored pigment, and a hydrogel component to a medium containing a hydrogel insolubilizer while stirring the medium, thereby causing the hydrogel component and the hydrogel insolubilizer to react with each other to produce a hydrogel. In the present invention, as described below, the colored gel particle raw material composition and the colored solid particles are mixed and added to a medium containing a hydrogel insolubilizer. The synthetic resin, the colored pigment, and the hydrogel (hydrogel constituent material and hydrogel insolubilizer) are exemplified below.

[0076] a) Synthetic resin The synthetic resin constituting the colored gel particles can be used in the form of a synthetic resin emulsion, which is a dispersion of synthetic resin particles in water or a water-containing solvent.

[0077] 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, especially acrylic silicone resin. For example, acrylic silicone resin and ceramic modified acrylic silicone resin are suitable.

[0078] An example of the acrylic silicone resin emulsion is "U-DOUBLE EF-023" manufactured by Nippon Shokubai Co., Ltd.

[0079] b) Color pigments Examples of color pigments that can be used to form the colored gel particles include, but are not limited to, titanium oxide, yellow iron oxide, red iron oxide (ferric oxide: red iron oxide), phthalocyanine blue, ochre, ultramarine blue, and carbon black.

[0080] The content of the color pigment is preferably 0.1 to 150 parts by weight, more preferably 0.5 to 100 parts by weight, and most preferably 1 to 80 parts by weight, based on 100 parts by weight of the solid content of the synthetic resin emulsion.

[0081] By reducing the content of the color pigment, the color solid particles in the hybrid color gel particles are not only irregularly exposed from the color gel particles, but also irregularly transparent, making it possible to realize novel designs with added transparency not found in conventional paints. In other words, such novel designs can be realized by adjusting the amount of the color pigment contained in the color gel particles so that the color of the color solid particles can be confirmed (visually recognized) through the color gel particles attached to the surface of the color solid particles. The transparency also differs depending on the thickness of the color gel particles attached to the surface of the color solid particles.

[0082] c) Hydrogel The hydrogel constituting the colored gel particles 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 exerts a gelling effect by forming a network structure for holding water in the gel, 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.

[0083] 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 may be used.

[0084] The organic compound is preferably a hydroxyl-containing organic polymer. 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 because they allow resins to be well dispersed and provide a hydrogel with excellent stability. Sodium alginate, a type of polysaccharide and dietary fiber, can also be used.

[0085] 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 mentioned. The water-swellable silicate compound may be a natural mineral or a synthetic compound. Among them, synthetic hectorite is preferred because it can produce a hydrogel with excellent stability.

[0086] Phosphates, borates, silicates, etc. can be used as hydrogel insolubilizers (gelling agents) that react or bond with hydrogel constituent materials to form joints in the network structure. Phosphates and borates are preferred because they can form good hydrogels that are difficult to dissolve in water. Phosphates are particularly preferred when the hydrogel constituent material is a water-swellable silicate compound such as hectorite, and borates are particularly preferred when the hydrogel constituent material is a hydroxyl group-containing organic polymer such as polyvinyl alcohol or guar gum. This is because they can form a hydrogel that is stable 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.

[0087] When a hydrogel component (main hydrogel ingredient) and a hydrogel insolubilizer (gelling agent) react or bond to form a network structure made of a hydrogel-forming substance, the two may simply be bonded additively, such as by addition, or they may be bonded by condensation, such as by dehydration, in which some of their atoms are detached and then bonded.

[0088] Although the hydrogel has been exemplified as a network structure formed by a hydrogel component and a hydrogel insolubilizer (gelling agent), the hydrogel may be formed by a mechanism other than the formation of the network structure. The colored gel particles may also contain an extender pigment such as calcium carbonate.

[0089] C. Hybrid colored gel particles in which colored solid particles and the above-mentioned colored gel particles are integrated The hybrid colored gel particles are composed of the colored solid particles and the colored gel particles. A plurality of hybrid colored gel particles (hybrid colored gel particle aggregates) are included in a colored gel particle mixture together with plain colored gel particles, which will be described later. As described above, in the hybrid colored gel particle aggregate, the colored solid particles are irregularly exposed from the colored gel particles. A method for producing a colored gel particle mixture containing such hybrid colored gel particles (hybrid colored gel particle aggregates) will be described later.

[0090] (2) Plain colored gel particles The plain colored gel particles are an essential component of the colored gel particle mixture, and a plurality of them (a large number of them) are included in the colored gel particle mixture. The plain colored gel particles are made of colored gel particles and do not contain colored solid particles.

[0091] As described above, the colored gel particles (plain colored gel particles) are obtained by adding a colored gel particle raw material composition containing a synthetic resin, a colored pigment, and a hydrogel component to a medium containing a hydrogel insolubilizer while stirring the medium, and reacting the hydrogel component with the hydrogel insolubilizer to generate a hydrogel. The colored gel particle raw material composition may contain an extender pigment such as calcium carbonate. In the present invention, a colored gel particle mixture raw material composition obtained by mixing a colored gel particle raw material composition and colored solid particles is added to a medium containing a hydrogel insolubilizer, and then, in addition to a large number of hybrid colored gel particles containing colored solid particles, a large number of plain colored gel particles not containing colored solid particles are usually obtained. As will be described below, the resulting plain colored gel particles will generally be much smaller than the hybrid colored gel particles. The materials of the colored gel particles are as described above, and therefore detailed description thereof will be omitted.

[0092] (3) A mixture of colored gel particles containing hybrid colored gel particles and plain colored particles.

[0093] A colored gel particle mixture is illustrated in Figure 1. The colored gel particle mixture includes a plurality of hybrid colored gel particles 1 and a plurality of plain colored particles 2. Note that only three representative hybrid colored gel particles 1 and three representative plain colored particles 2 are labeled. Moreover, the hybrid colored gel particles 1 illustrated in Fig. 1 and Fig. 2 are in an embodiment in which the colored gel particles 11 are attached to a portion of the surface of the colored solid particles 12. Fig. 1 is an example in which a pulverized coating film is used as the colored solid particles 12, and Fig. 2 is an example in which celven is used as the colored solid particles 12. These embodiments are also included in the concept of colored solid particles being exposed from the colored gel particles. It can be seen that in the hybrid colored gel particles, the colored solid particles are irregularly exposed from the colored gel particles (in the hybrid colored gel particles 1 in these figures, the colored solid particles 12 are irregularly exposed from the colored gel particles 12 attached to the surface). It should be noted that the plain colored gel particles 2 are usually much smaller than the hybrid colored gel particles 1.

[0094] 2. Method for producing colored gel particle mixture Next, a method for producing a colored gel particle mixture will be described. The method for producing a colored gel particle mixture includes a raw material composition blending step S1 and a raw material composition gelling step S2, as shown in Fig. 3. The obtained colored gel particle mixture is an aggregate of a plurality of hybrid colored gel particles (including colored solid particles) and a plurality of plain colored gel particles (not including colored solid particles).

[0095] (1) Raw material composition blending process The raw material composition blending step S1 is a step of mixing a colored gel particle raw material composition with colored solid particles to obtain a colored gel particle mixture raw material composition.

[0096] A. Colored gel particle raw material composition The colored gel particle raw material composition contains a synthetic resin, a color pigment, and hydrogel constituent materials. Each of the constituent materials has been described above, so description thereof will be omitted. The weight of the colored gel particle raw material composition corresponds to the weight of the colored gel particles (the colored gel particles of the hybrid colored gel particles and the colored gel particles of the plain colored gel particles) contained in the colored gel particle mixture.

[0097] B. Colored solid particles The colored solid particles have also been described above, so a detailed description thereof will be omitted.

[0098] C. Mixed In the raw material composition blending step, the colored gel particle raw material composition and the colored solid particles are mixed and stirred until uniformly dispersed, etc., to obtain a colored gel particle mixture raw material composition. During mixing, the synthetic resin, colored pigment, and hydrogel constituent material constituting the colored gel particle raw material composition can be directly mixed with the colored solid particles. If desired, optional components such as a water solvent, a body pigment, a preservative, a thickener, and various additives can be added. An example of the body pigment is calcium carbonate.

[0099] At this time, it is necessary to mix and blend the colored solid particles so that the amount of the colored solid particles is 0.5 to 60 parts by weight per 100 parts by weight of the colored gel particle raw material composition, so that the colored gel particle mixture described below contains 0.5 to 60 parts by weight of the colored solid particles per 100 parts by weight of the colored gel particles.

[0100] The content of the synthetic resin emulsion in the colored gel particle mixture 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.

[0101] The content of the color pigment in the colored gel particle mixture raw material composition is preferably 0.1 to 30% by weight, more preferably 0.5 to 20% by weight, further preferably 2 to 15% by weight, and most preferably 5 to 10% by weight.

[0102] The content of the hydrogel constituent material in the colored gel particle mixture raw material composition is preferably 3 to 100 parts by weight in terms of solid content, more preferably 10 to 80 parts by weight in terms of solid content, even more preferably 25 to 70 parts by weight, and most preferably 40 to 60 parts by weight in terms of solid content, relative to 100 parts by weight of the solid content of the synthetic resin emulsion.

[0103] (2) Raw material composition gelation process The raw material composition gelation process S2 is a process in which the colored gel particle mixture raw material composition is added to a medium containing a hydrogel insolubilizer while stirring, causing the hydrogel components and the hydrogel insolubilizer to react with each other to generate a hydrogel, thereby obtaining a colored gel particle mixture. The colored gel particle mixture includes a plurality of hybrid colored gel particles (hybrid colored gel particle aggregates) and a plurality of plain colored gel particles (plain colored gel particle aggregates).

[0104] A. Hydrogel insolubilizer The hydrogel insolubilizer reacts with or bonds to the hydrogel constituent materials to form joints in the network structure. The hydrogel insolubilizer has also been described above, so a detailed description thereof will be omitted.

[0105] The concentration of the hydrogel insolubilizer (gelling agent) in the aqueous solution is preferably 0.01 to 1.0% by weight, more preferably 0.1 to 0.8% by weight, even more preferably 0.2 to 0.7% by weight, and most preferably 0.4 to 0.6% by weight.

[0106] B. Colored gel particle mixture A colored gel particle mixture is obtained by adding the colored gel particle raw material composition to a medium containing a hydrogel insolubilizer (gelling agent) while stirring the medium.

[0107] As described above, when the colored gel particle mixture raw material composition is added to a medium containing a hydrogel insolubilizer while stirring it, not only hybrid colored gel particles containing colored solid particles but also plain colored gel particles not containing colored solid particles are usually obtained.

[0108] Then, in the raw material composition blending step, the colored solid particles are blended in an amount of 0.5 to 60 parts by weight per 100 parts by weight of the colored gel particle raw material composition, and the colored gel particle mixture raw material composition is added while stirring a medium containing a hydrogel insolubilizer (gelling agent) so that the average particle diameter of the colored solid particles is 1 and the average particle diameter of the colored gel particle mixture is 0.2 to 5.0. As a result, the hybrid colored gel particles include those in which the colored solid particles are irregularly exposed from the colored gel particles, and when the hybrid colored gel particle aggregate is viewed as a whole, the colored solid particles are irregularly exposed from the colored gel particles. In other words, when viewed as a whole hybrid colored gel particle aggregate, the position, size, and range where the colored solid particles are exposed from the colored gel particles (or the colored gel particles are attached to the colored solid particles) differ between the hybrid colored gel particles.

[0109] The average particle size of the colored gel particle mixture is the overall average particle size of the hybrid colored gel particles and plain colored gel particles contained in the colored gel particle mixture, and is the average of the particle sizes of a large number of these colored gel particles. The particle size can be measured by observing these colored gel particles with a microscope or the like. For example, the obtained colored gel particle mixture is mixed with an aqueous synthetic resin emulsion clear paint in a ratio of about 1:10 (by weight), and the resulting mixture is poured into a 10 cm 2 The outer diameter can be measured by applying the coating to an ABS plate, drying it, and observing it with a microscope. 2 ) the particle sizes of the hybrid colored gel particles and the plain colored gel particles present therein are measured and averaged to obtain the average particle size.

[0110] When the colored gel particle mixture raw material composition is added while stirring the medium containing the hydrogel insolubilizer, the size of the hybrid colored gel particles or plain colored gel particles, the amount of colored gel particles adhering to the colored solid particles in the hybrid colored gel particles, and the like can be adjusted by adjusting the viscosity of the colored gel particle mixture raw material composition, the temperature of the medium containing the hydrogel insolubilizer, the stirring speed, the stirring time, and the like. As illustrated in FIG. 1, the resulting plain colored gel particles 2 are typically much smaller than the hybrid colored gel particles 1.

[0111] 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 time for leaving the mixture at rest is usually about 24 hours, at which point the formed gel 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 to obtain a colored gel particle mixture. The resulting colored gel particle mixture contains hybrid colored gel particles and plain colored gel particles. The hybrid colored gel particles can be separated from the colored gel particle mixture using, for example, a mesh.

[0112] 3. Paints such as multicolored pattern paints containing colored gel particle mixtures The colored gel particle mixture or hybrid colored gel particle aggregate can be used in paints such as multicolored paints, etc. This paint can realize coating films with unprecedented and novel designs.

[0113] The paint containing the colored gel particle mixture or hybrid colored gel particle aggregate is not particularly limited. For example, the paint may contain a colored gel particle mixture or hybrid colored gel particle aggregate and a synthetic resin emulsion. If desired, the paint may contain optional components such as color pigments, extender pigments, preservatives, thickeners, various additives, and water solvents. In addition, a multicolored pattern paint may be prepared by blending a colored gel particle mixture of multiple colors.

[0114] In addition, the paint containing the colored gel particle mixture or the like may contain not only the colored gel particle mixture or the like, but also conventional colored gel particles in addition to the colored gel particle mixture or the like. By using the colored gel particle mixture or the like in combination with conventional colored gel particles, the design can be adjusted.

[0115] There is no particular limitation on the surface to which such a coating material is applied. For example, the coating material can be applied to wall panels, or the exterior and interior walls of buildings. There is also no particular limitation on the material of the surface to be coated. For example, porcelain, tiles, concrete, ALC panels, PC panels, mortar, siding boards, extrusion molding boards, gypsum boards, steel plates, 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.

[0116] The method for applying the coating material containing the colored gel particle mixture or the hybrid colored gel particle aggregate to the surface of the surface to be coated is not particularly limited, and can be, for example, spray coating or roller coating.

[0117] 4. Wall panels, wall structures and buildings

[0118] Paints such as multicolored paints containing colored gel particle mixtures can be suitably used on wall panels, particularly wall panels with rough textures such as ALC panels, PC panels, panels with grating grooves, and panels with a rock-like appearance.

[0119] Furthermore, a wall structure (exterior wall structure, interior wall structure) using such a wall panel and a building having such a wall structure have an even more innovative design that has not been seen before. EXAMPLES

[0120] 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 the like are based on weight.

[0121] 1. Preparation of colored gel particle mixture Example 1 A colored gel particle mixture was prepared based on the recipe of Example 1 in Table 1 below. First, a synthetic resin emulsion (Japan Catalyst Co., Ltd.'s "U-DOUBLE EF-023"), a color pigment (brown), an extender pigment (Shiraishi Calcium Co., Ltd.'s "Whiten 305"), and water (tap water) were mixed together, and then color film (crushed material) was added as colored solid particles. Then, a PVA resin solution ("Elvanol 71-30" manufactured by Kuraray Co., Ltd.), which is a hydrogel component, and an aqueous solution of sodium alginate (1% aqueous solution of "Kimica Algin Hight I-3G" manufactured by Kimica Co., Ltd.) were mixed and stirred to obtain a colored gel particle mixture raw material composition. The weight of the colored gel particle raw material composition in Table 1 corresponds to the weight of the colored gel particles (colored gel particles of hybrid colored gel particles and colored gel particles of plain colored gel particles). Therefore, (weight of colored solid particles / weight of colored gel particle raw material composition)×100=the amount (parts by weight) of colored solid particles per 100 parts by weight of colored gel particles. The obtained mixed and stirred solution (colored gel particle mixture raw material composition) was poured into an aqueous solution containing a hydrogel insolubilizer (0.4% ammonium borate) while stirring, and stirring was continued until the colored gel particle mixture had an average particle diameter of 1.5 mm, thereby insolubilizing the particles and obtaining a colored gel particle mixture. The evaluation item of irregular exposure of colored solid particles was visually evaluated by multiple persons.

[0122] The obtained colored gel particle mixture was composed of a large number of hybrid colored gel particles (hybrid colored gel particle aggregates) containing colored solid particles, and plain colored gel particles not containing colored solid particles, and in the hybrid colored gel particles (aggregates), the colored solid particles were irregularly exposed from the colored gel particles (evaluated as ○).

In addition, the amount of colored solid particles per 100 parts by weight of colored gel particles was increased (14.0 parts by weight to 27.5 parts by weight).

[0125] In the obtained colored gel particle mixture, colored solid particles were irregularly exposed from the colored gel particles of the hybrid colored gel particles (aggregate) (rating: ⊚).

[0127] In the obtained colored gel particle mixture, colored solid particles were irregularly exposed from the colored gel particles of the hybrid colored gel particles (aggregate) (evaluated as ◯).

[0128] Example 4 Based on the formulation of Example 2, the type of colored solid particles was changed (color film → mica), and the formulation of the color pigment was changed so that the color tone of the colored gel particles became black. Also, the amount of colored solid particles per 100 parts by weight of colored gel particles was reduced (27.5 parts by weight → 5.6 parts by weight).

[0129] In the obtained colored gel particle mixture, colored solid particles were irregularly exposed from the colored gel particles of the hybrid colored gel particles (aggregate) (evaluated as ◯).

[0130] Example 5 Based on the formulation of Example 1, the formulation of the color pigment was changed so that the color tone of the colored gel particles would be light brown, and some of the hydrogel constituent materials were changed (sodium alginate aqueous solution → guar gum aqueous solution).

[0131] In the obtained colored gel particle mixture, colored solid particles were irregularly exposed from the colored gel particles of the hybrid colored gel particles (aggregate) (evaluated as ◯).

[0132] Comparative Example 1 Based on the formulation of Example 1, the type of colored solid particles was changed (color film → barite), the formulation of the color pigment was changed so that the color tone of the colored gel particles would be light brown, and some of the hydrogel constituent materials were changed (sodium alginate aqueous solution → guar gum aqueous solution). Also, the amount of colored solid particles per 100 parts by weight of colored gel particles was increased (14.0 parts by weight → 27.4 parts by weight).

[0133] The obtained colored gel particle mixture had small colored solid particles, and the appearance of the colored solid particles irregularly exposed from the colored gel particles of the hybrid colored gel particles (aggregate) could not be visually confirmed (evaluated as x).

[0134] Comparative Example 2 Based on the formulation of Example 1, the type of colored solid particles was changed (color film → ethylene vinyl acetate foam), the formulation of the color pigment was changed so that the color tone of the colored gel particles would be light brown, and some of the hydrogel constituent materials were changed (sodium alginate aqueous solution → guar gum aqueous solution). Also, the amount of colored solid particles per 100 parts by weight of colored gel particles was significantly reduced (14.0 parts by weight → 0.3 parts by weight).

[0135] The resulting colored gel particle mixture had a small amount of colored solid particles, and the colored solid particles were not exposed from the colored gel particles of the hybrid colored gel particles (evaluated as x).

[0136] The obtained colored gel particle mixture had a large amount of colored solid particles, and although the colored solid particles were exposed from the colored gel particles of the hybrid colored gel particles, the exposure was excessive and the exposure was not irregular as a hybrid colored gel particle aggregate (evaluated as ×).

[0137] 2. Preparation of paint containing irregularly shaped colored gel particles A paint was prepared using the colored gel particle mixtures of the above Examples 1 to 5. As the synthetic resin emulsion, "U-DOUBLE EF-008" by Nippon Shokubai Co., Ltd. was used.
