[0001] This invention relates to a decorative method applicable to buildings and the like. [Background technology]

[0002] Traditionally, concrete, mortar, and various types of panel-like wall materials have been used for the walls of buildings and other structures. In order to enhance the aesthetic appeal of such walls, textured patterns are sometimes created on the surface to give them a three-dimensional, sculptural appearance.

[0003] Such walls are exposed to the outdoors for long periods, and their deterioration progresses due to the effects of sunlight, rain, and other factors. Therefore, painting is done to create a protective coating on the surface and suppress deterioration over time.

[0004] For example, Japanese Patent Publication No. 6-306305 describes a method for applying a sealer to the existing paint film surface of the exterior wall of a building, and then applying a water-based thick-film elastic paint as a topcoat. [Prior art documents] [Patent Documents]

[0010] According to the present invention, the aesthetic appeal of the wall surface can be enhanced. [Modes for carrying out the invention]

[0011] The following describes embodiments for carrying out the present invention.

[0012] [Wall surface] The present invention can be applied to the walls of buildings, civil engineering structures, etc. Examples of base materials that constitute such walls include concrete, mortar, metal, wood, glass, etc., or various plate-shaped wall materials. Among these, plate-shaped wall materials include inorganic hardened bodies mainly composed of cement, calcium silicate, lime, gypsum, etc. Specific examples of such plate-shaped wall materials include cement boards, extruded boards, slate boards, PC boards, ALC boards, fiber-reinforced cement boards, siding boards, ceramic boards, calcium silicate boards, gypsum boards, hard wood chip cement boards, etc.

[0013] In this invention, the wall surface can be one having an uneven or textured pattern on its surface. In this case, the present invention provides a particularly excellent effect in improving the aesthetic appearance. Various types of uneven or textured patterns can be used on the wall surface, such as tile patterns, brick patterns, geometric patterns, stripe patterns, grid patterns, polka dot patterns, sand wall patterns, orange peel patterns, ripple patterns, and other graphic patterns that depict animals or plants. Specifically, the shape of the protrusions when viewed from the front of the uneven or textured pattern can be, for example, a square, rectangle, circle, ellipse, triangle, rhombus, polygon, or irregular shape. The cross-sectional shape of the protrusions in the uneven or textured pattern can be, for example, a trapezoid, square, rectangle, semicircle, wave, step shape, triangle, or mountain shape. These protrusions may also be multi-stage shapes. Examples of recesses in the uneven or textured pattern can be flat and form joints. The height difference between the recesses and protrusions may be constant or vary in each part, but is preferably 20 mm or less, more preferably about 1 to 15 mm. In this invention, "α~β" is synonymous with "α or greater and β or less".

[0014] The wall surface in this invention may have an existing coating (previous paint film) on the surface of the substrate. This existing coating is a variety of coatings that have already been applied to the substrate by on-site painting or factory painting (line painting), etc. Examples of such existing coatings include colored coatings (enamel coatings, printed coatings, etc.), clear coatings, or laminated coatings thereof, etc., which are formed by applying and curing various coating materials to the substrate. Such coating materials may be any of the following: room temperature drying type, room temperature curing type, bake curing type, ultraviolet (UV) curing type, electron beam curing type, etc.

[0015] Examples of binders for such coating materials include organic binders such as acrylic resins, polyurethane resins, epoxy resins, fluororesins, alkyd resins, and polyester resins, or inorganic binders such as silicone resins, alkoxysilanes, colloidal silica, and silicates, and organic-inorganic composite binders such as acrylic silicone resins.

[0016] The present invention can be applied as a method for renovating walls that have deteriorated over time. The degree of deterioration is not particularly limited, but walls that have been used for approximately 5 years or more (and even 8 years or more) can be targeted by the present invention.

[0017] [Top coat material] The present invention relates to a decorative method that includes the step of applying a topcoat to a wall surface. The topcoat in this invention consists of liquid or gel-like color particles dispersed in an aqueous medium. By using such a topcoat, the present invention makes it possible to achieve a decorative effect with a thin film, and if the wall surface has an uneven pattern, it is possible to obtain a finish that takes advantage of that uneven pattern. Such topcoats are classified into oil-in-water (O / W) or water-in-water (W / W) types depending on the combination of color particles and aqueous medium that constitute the topcoat (color particles / aqueous medium). In this invention, water-in-water (W / W) type topcoats are preferred. The weight ratio of color particles to aqueous medium (color particles:aqueous medium) is preferably 1:99 to 80:20 (more preferably 10:90 to 75:25, and even more preferably 30:70 to 70:30).

[0018] The color particles in the topcoat material are a coloring agent containing a resin, a coloring pigment, and various additives as needed, dispersed in a liquid or gel-like state in an aqueous medium. Examples of resins in the coloring agent include acrylic resin, urethane resin, vinyl acetate resin, acrylic vinyl acetate resin, acrylic urethane resin, acrylic silicone resin, fluororesin, polyvinyl alcohol, biogum, galactomannan derivative, alginic acid derivative, and cellulose derivative. When such a resin is in the form of a water-soluble resin and / or a water-dispersible resin (resin emulsion), dispersing the coloring agent in an aqueous medium results in a water-in-water (W / W) type topcoat material. The resin solids content ratio in the coloring agent is preferably 50% by weight or less, more preferably 3 to 40% by weight, and even more preferably 5 to 30% by weight.

[0019] In colorants, the coloring pigment is a component that imparts color to the topcoat material. Examples of coloring pigments include inorganic chromatic pigments such as ferric oxide (red iron oxide), yellow iron oxide, ultramarine, and cobalt green; organic chromatic pigments such as azo, naphthol, pyrazolone, anthraquinone, perylene, quinacridone, disazo, isoindolinone, benzimidazole, phthalocyanine, and quinophthalone; black pigments such as carbon black, iron-manganese composite oxide, iron-copper-manganese composite oxide, iron-chromium-cobalt composite oxide, copper-chromium composite oxide, copper-manganese-chromium composite oxide, and black iron oxide; white pigments such as titanium dioxide, zinc oxide, and alumina; and other pigments such as pearl pigments, aluminum pigments, luminescent pigments, phosphorescent pigments, and fluorescent pigments. These can be used individually or in combination of two or more. The average particle size of the coloring pigment is preferably 1 μm or less, more preferably 0.01 to 0.9 μm. In this invention, the average particle size of the pigment is the average value measured using a laser diffraction particle size distribution analyzer (measurement temperature is 25°C).

[0020] The ratio of coloring pigment in the coloring agent is preferably 0.5 to 10% by weight, more preferably 0.55 to 9% by weight, and even more preferably 0.6 to 8% by weight, from the viewpoint of color development, design, etc.

[0021] The method for dispersing the coloring agent in granular form in an aqueous medium is not particularly limited, and known methods can be employed. For example, a method conforming to the material manufacturing method specified in JIS K5667:2003 "Multicolor Pattern Paints" can be employed. Specifically, a method of dispersing the coloring agent in an aqueous medium containing a dispersion stabilizer can be employed. The dispersion stabilizer is a component that stabilizes the coloring agent in granular form and can be selected according to the type of resin and coloring agent. Specific examples of dispersion stabilizers include magnesium salts, calcium salts, barium salts, aluminum salts, sodium salts, potassium salts, borates, phosphates, etc. In addition, water-soluble polymers, clays, etc. can also be used as dispersion stabilizers. The aqueous medium may also contain the same resin as described above (water-soluble resin, resin emulsion, etc.). The resin solids content ratio in the aqueous medium is preferably 50% by weight or less, more preferably 3 to 40% by weight, and even more preferably 5 to 30% by weight.

[0022] Colorants and aqueous media can each contain various additives. Examples of such additives include extender pigments, aggregates, fillers, matting agents, fibers, gel-forming agents, pigment dispersants, emulsifiers, thickeners, film-forming aids, leveling agents, coupling agents, wetting agents, plasticizers, antifreeze agents, pH adjusters, drying adjusters, preservatives, antifungal agents, antialgal agents, antibacterial agents, defoaming agents, adsorbents, deodorizers, UV absorbers, light stabilizers, antioxidants, catalysts, and crosslinking agents.

[0023] The inclusion of extender pigments in the coloring agent and / or aqueous medium allows the topcoat film to be made matte, which is preferable in terms of improving the effects of the present invention. In the present invention, it is particularly preferable that the coloring agent and aqueous medium include extender pigments. Examples of extender pigments include heavy calcium carbonate, granite, light calcium carbonate, white carbon, talc, kaolin, clay, pottery clay, china clay, diatomaceous earth, barite powder, barium sulfate, precipitated barium sulfate, silica sand, silica powder, quartz powder, resin beads, etc., and these can be used one or more of each. The refractive index of the extender pigment is preferably 1.4 to 1.7. The average particle size of the extender pigment is preferably 50 μm or less, more preferably 0.1 to 30 μm, and even more preferably 0.5 to 20 μm.

[0024] The extender pigment ratio in the coloring agent is preferably 3% by weight or more, more preferably 5 to 40% by weight. The extender pigment ratio in the aqueous medium is preferably 3% by weight or more, more preferably 5 to 40% by weight.

[0025] The particle size and shape of the color particles can be set as appropriate. Specifically, the shape of the stirring blades during manufacturing, the size and position of the stirring blades relative to the stirring tank, the rotation speed of the stirring blades, the viscosity of the coloring agent, the method and concentration of adding the dispersion stabilizer, the viscosity of the aqueous medium, etc., can be appropriately selected and adjusted. The particle size of the color particles is preferably 0.01 to 10 mm (more preferably 0.1 to 8 mm).

[0026] The topcoat material in the present invention has color particles consisting of main color particles, or the main color particles and the difference in brightness (△L) between them. * The absolute value of |△L *It consists of secondary color particles where (description omitted) is 10 or less. In the present invention, by using such a topcoat material, a finish with excellent aesthetics, such as texture and feel, can be obtained. Such an effect is different from the uniform single-color finish by a general colored paint. It is considered to be achieved by the action that the color is expressed by the aggregation of particles in the order of millions, and when the observer views the color from a certain distance or more, it is visually recognized as almost one color as a whole. In the present invention, the main color particles are those that show the main color tone among the color particles contained in the topcoat material, and refer to the color particles with the largest weight ratio among the color particles.

[0027] As the aspect of the color particles in the topcoat material, (1) The aspect where the color particles consist of main color particles, (2) The aspect where the color particles consist of main color particles and secondary color particles with a lightness difference (|△L * |) of 6 or less from the main color particles, can be mentioned. The aspect of (1) above is that the color particles consist of only one color of main color particles. The aspect of (2) above is that the color particles consist of main color particles and at least one or more (preferably 1 to 5 kinds) of secondary color particles. The color tone of the main color particles can be appropriately set according to the desired finish and the like.

[0028] In the aspect of (2) above, the secondary color particles have a lightness difference (|△L * |) of 10 or less from the main color particles, preferably more than 0.8 and 9.5 or less, more preferably 0.9 or more and 9 or less. Thus, different from a general multi-color pattern paint, the effect of the present invention can be enhanced by the mixture of color particles having a slight lightness difference.

[0029] In the aspect of (2) above, when the main color particles are light colors (L * ≧50), the secondary color particles preferably have a lightness difference (|△L * |) of 6 or less from the main color particles, more preferably more than 0.8 and 5 or less, still more preferably 0.9 or more and 4.5 or less, and particularly preferably 1 or more and 4 or less.

[0030] In the above (2) configuration, the main color particles are dark (L * If <50), the secondary color particles have a lightness difference (|△L) from the primary color particles. * It is preferable that |) is 10 or less, more preferably 2 to 9.5, and even more preferably 4 to 9.

[0031] In the embodiment of (2) above, the secondary color particles have a Δa relationship with the primary color particles. * The absolute value of (|△a * | is also written as: ), △b * The absolute value of (|△b) * | (This can also be written as ).) However, it is preferable that all of these values ​​be 1 or less, more preferably 0.8 or less, even more preferably 0.6 or less, and particularly preferably 0.5 or less. In this way, unlike general multi-color paints, the effects of the present invention can be enhanced by mixing color particles that have almost the same hue but only slight differences in brightness.

[0032] Note that △L in the present invention * , △a * , △b * These are all values ​​measured using a colorimeter, L * value, a * value, b * The value (average of 3 or more measurement points) can be calculated using the following formula. △L * =L * 2-L * 1 △a * =a * 2-a * 1 △b * =b * 2-b * 1 (In the formula, L * 1, a * 1, b * 1 represents the L of the main color grains. * a * , b * L * 2, a * 2, b * 2 represents the L of the secondary color particles.* a * , b * ) For the above measurements, the colorants constituting each color particle can be applied to standard white paper to a thickness of 500 μm, and the resulting film can be used after drying for 48 hours under standard conditions (temperature 23°C, relative humidity 50%).

[0033] The weight ratio of primary color particles to secondary color particles in the topcoat material (weight of primary color particles:weight of secondary color particles) is preferably 30:70 to 100:0, more preferably 40:60 to 98:2, even more preferably 50:50 to 95:5, and particularly preferably 55:45 to 90:10.

[0034] In the topcoat material of the present invention, at least one of the color particles is transparent. By having such transparent color particles (transparent color particles), the present invention can impart a sense of depth to the topcoat film, which is advantageous in terms of improving design aesthetics. In the topcoat material, the weight ratio of transparent color particles to the total weight of color particles {(weight of transparent color particles / total weight of color particles) × 100} is preferably 20% by weight or more, more preferably 40% by weight or more, and even more preferably 60 to 100% by weight. Transparent color particles are obtained by using a transparent coloring material as the coloring material that constitutes the color particles.

[0035] Transparent colorants can be obtained by adjusting the ratio of color pigments in the colorant so that the colorant exhibits transparency. The ratio of color pigments in a transparent colorant is preferably 0.5 to 5% by weight, more preferably 0.55 to 3% by weight, and even more preferably 0.6 to 2.5% by weight.

[0036] The opacity of the transparent coloring agent is preferably less than 90%, more preferably 5% to less than 80%, even more preferably 15 to 78%, and particularly preferably 25 to 75%. Having such an opacity allows for the production of transparent color particles, which are advantageous in terms of color development and depth. The opacity can be measured according to the method specified in JIS K5663:2003 "Synthetic Resin Emulsion Paints and Sealers," section 7.9 "Opacity."

[0037] Examples of embodiments of the topcoat material that include transparent color particles include embodiments in which the main color particles are transparent, embodiments in which at least one type of secondary color particle is transparent, or embodiments in which the main color particle and at least one type of secondary color particle are transparent. Embodiments in which all of the main color particle and secondary color particle are transparent are also preferred.

[0038] The topcoat material in the present invention may include opaque color particles as color particles other than transparent color particles. Opaque color particles can be obtained by setting the ratio of color pigment in the coloring material and the opacity of the coloring material to be relatively high. The ratio of color pigment in the coloring material constituting the opaque color particles (opaque coloring material) is preferably 1.5 to 10% by weight, more preferably 2 to 9% by weight, and even more preferably 2.6 to 8% by weight. The opacity of the opaque coloring material is preferably 90% or more, more preferably 93% or more.

[0039] The average particle size of the main color particles and secondary color particles in the topcoat is preferably 0.5 to 8 mm, more preferably 1 to 6 mm. The average particle size of the secondary color particles is preferably 20 to 300%, more preferably 40 to 250%, even more preferably 50 to 200%, and particularly preferably 60 to 180% of the average particle size of the main color particles. When each color particle contained in the topcoat satisfies these conditions, it is possible to suppress the occurrence of protrusions caused by the topcoat film itself and to make the dried film thickness of the topcoat film uniform, which is advantageous in terms of improving design. When the topcoat is applied to a wall surface with an uneven pattern, it is also advantageous as it is possible to fully utilize the uneven pattern of the wall surface. The average particle size of the color particles is obtained by calculating the average of the major diameters of 50 randomly selected color particles in a film obtained by applying the topcoat to a standard white paper with a film applicator (gap of 1.5 mm) and drying it.

[0040] The topcoat material in the present invention can form a matte film. Such a topcoat material is preferable in terms of improving the effects of the present invention, such as improving the aesthetic qualities of texture and feel. The degree of "mattiness" of the topcoat film can be defined by its specular gloss. The specular gloss of the topcoat film (measured at a 60-degree angle) is preferably 40 or less, more preferably 20 or less, even more preferably 10 or less, and particularly preferably 6 or less. Such a matte topcoat material can be obtained by including extender pigments in the coloring agent and / or aqueous medium. In particular, when the topcoat material includes extender pigments in both the coloring agent and the aqueous medium, partial differences in gloss are difficult to see from any angle the wall surface is viewed from, and a sufficiently uniform matte film can be seen. This effect is especially pronounced when the topcoat material is applied to a wall surface with an uneven pattern. The specular gloss of the topcoat material is obtained by applying the topcoat material to a standard white paper using a film applicator (1.5 mm gap), and then drying the coated surface horizontally under standard conditions for 48 hours. The specular gloss is measured (average value from 10 or more measurement points at a measurement angle of 60 degrees).

[0041] The topcoat material in the present invention may consist of the above-mentioned color particles and decorative particles other than the above-mentioned color particles dispersed in an aqueous medium. As decorative particles, for example, solid particles other than the above-mentioned color particles can be used, and various types of solid particles such as transparent or opaque, uncolored or colored can be used. The particle size of the decorative particles is preferably 0.01 to 10 mm (more preferably 0.1 to 8 mm). A topcoat material containing such decorative particles is suitable in terms of improving the effects of the present invention, such as improving aesthetics due to the accenting effect of the decorative particles.

[0042] As an example of decorative granules, flaky solid particles can be used. Examples of such flaky solid particles include mica, sericite, shell fragments, coral fragments, wood fragments, resin flakes, glass flakes, and metal flakes. These may be colored or fired.

[0043] [Makeup Method] The present invention includes the step of applying a topcoat material to a wall surface.

[0044] Before applying the topcoat, the wall surface can be treated as needed. Examples of surface treatments include cleaning, scraping, filler application, putty application, primer application, and sealer application. Such surface treatments can be performed appropriately, taking into consideration, for example, the type and condition of the existing coating.

[0045] Before applying the topcoat, a step of applying a colored primer can be performed. As a colored primer, for example, one containing resin and a coloring pigment that can form a uniform single-color film through its color development can be used.

[0046] As resins used in colored primers, for example, water-soluble resins such as water-soluble resins and water-dispersible resins, non-water-based resins such as solvent-soluble resins and non-water-dispersible resins, or solvent-free resins can be used. Of these, when a water-soluble resin is used as the resin, a water-soluble colored primer can be obtained. Examples of resin types include acrylic resins, urethane resins, epoxy resins, vinyl acetate resins, acrylic vinyl acetate resins, acrylic urethane resins, acrylic silicone resins, and fluororesins. These can be used individually or in combination of two or more types.

[0047] Examples of coloring pigments used in colored primers include inorganic chromatic pigments such as ferric oxide (red iron oxide), yellow iron oxide, ultramarine, and cobalt green; organic chromatic pigments such as azo, naphthol, pyrazolone, anthraquinone, perylene, quinacridone, disazo, isoindolinone, benzimidazole, phthalocyanine, and quinophthalone; black pigments such as carbon black, iron-manganese composite oxide, iron-copper-manganese composite oxide, iron-chromium-cobalt composite oxide, copper-chromium composite oxide, copper-manganese-chromium composite oxide, and black iron oxide; white pigments such as titanium dioxide, zinc oxide, and alumina; and other pigments such as pearl pigments, aluminum pigments, luminescent pigments, phosphorescent pigments, and fluorescent pigments. These can be used individually or in combination of two or more. The average particle size of the coloring pigment is preferably 1 μm or less, more preferably 0.01 to 0.9 μm. The mixing ratio of the coloring pigment is preferably 1 to 500 parts by weight, more preferably 5 to 300 parts by weight, and even more preferably 10 to 200 parts by weight, per 100 parts by weight of resin, in terms of solid content.

[0048] The color tone of the colored undercoat can be set to an approximate color of the topcoat, for example, the color difference (△E) between the undercoat and the main color particles in the topcoat can be set to 5 or less. The color tone of the colored undercoat can be set by appropriately adjusting, for example, the type of coloring pigment, the mixing ratio, etc.

[0049] Furthermore, the colored primer can form a matte film, and the specular gloss of the colored primer film (measurement angle 60 degrees) is preferably 40 or less, more preferably 20 or less, even more preferably 10 or less, and particularly preferably 6 or less. Such a matte colored primer is suitable in terms of improving the effects of the present invention. The specular gloss of the colored primer is a value obtained by applying the colored primer to a glass plate using a film applicator with a gap of 150 μm, and then measuring the specular gloss (measurement angle 60 degrees, average value of 10 or more measurement points) after drying the coated surface horizontally under standard conditions for 48 hours.

[0050] Such matte colored primers preferably contain extender pigments. Examples of extender pigments in matte colored primers include heavy calcium carbonate, granite, light calcium carbonate, white carbon, talc, kaolin, clay, earthenware clay, china clay, diatomaceous earth, barite powder, barium sulfate, precipitated barium sulfate, silica sand, silica powder, quartz powder, resin beads, etc., and these can be used individually or in combination of two or more. The refractive index of such extender pigments is preferably 1.4 to 1.7, and their average particle size is preferably 0.5 to 100 μm, more preferably 1 to 50 μm. The mixing ratio of the extender pigments is preferably 20 to 400 parts by weight, more preferably 40 to 300 parts by weight, and even more preferably 60 to 200 parts by weight, per 100 parts by weight of resin, in terms of solid content.

[0051] In addition to the components mentioned above, the colored primer may also contain various additives. Examples of such additives include pigment dispersants, emulsifiers, viscosity modifiers, film-forming aids, leveling agents, coupling agents, wetting agents, plasticizers, antifreeze agents, pH adjusters, preservatives, antifungal agents, antialgal agents, antibacterial agents, defoaming agents, adsorbents, deodorizers, ultraviolet absorbers, light stabilizers, antioxidants, catalysts, crosslinking agents, solvents, and water. The colored primer can be manufactured by uniformly mixing these components using conventional methods.

[0052] For applying the colored primer, methods such as spray application, roller application, trowel application, and brush application can be used. The amount of colored primer applied is preferably 0.05 to 1 kg / m². 2 More preferably 0.1 to 0.8 kg / m 2 It is desirable to apply the colored primer evenly to the entire wall surface to be painted. The application and drying of the colored primer should preferably be carried out at room temperature (0-40°C).

[0053] In this invention, the topcoat is applied after performing the above surface treatment, applying a colored primer, etc., as necessary. When a colored primer is applied, it is desirable to apply the topcoat after the colored primer film has dried. It is desirable to apply the topcoat directly to the uniform single-color film formed by the colored primer. This results in a highly aesthetic finish with excellent texture, feel, and depth, which appears as almost a single color overall (when viewed by an observer from a certain distance or more).

[0054] For the application method of the topcoat, for example, spray application, roller application, or brush application can be used. The amount of topcoat applied is preferably 0.3 to 1.5 kg / m². 2 , more preferably 0.5~1.2 kg / m 2 More preferably 0.55 to 0.95 kg / m 2 The lower limit of the amount of topcoat applied is the above value, which is advantageous in terms of color development and design. The upper limit of the amount of topcoat applied is the above value, which provides a sufficient improvement in aesthetics, and if the wall surface has an uneven pattern, it is possible to maintain that uneven pattern while sufficiently enhancing the design. The application or drying of the topcoat may preferably be carried out at room temperature.

[0055] When applying the topcoat, the viscosity can be adjusted as needed by mixing in a diluent such as water. The dilution ratio is preferably 0 to 10% by weight. The viscosity of the topcoat to be applied is preferably 1 to 30 Pa·s (more preferably 2 to 20 Pa·s), and the thixotropy index is preferably 2 to 9 (even more preferably 3 to 8).

[0056] In this invention, the film of the topcoat material can be made the outermost surface, and if necessary, a clear coat material can be applied to the surface of the film of the topcoat material. The clear coat material can be applied after the film of the topcoat material has dried.

[0057] As the clear coat material, for example, acrylic resin, urethane resin, silicone resin, acrylic silicone resin, fluororesin, etc., or composite resins thereof, or materials containing colloidal silica, etc., can be used. These may have crosslinking reactivity, and depending on the purpose, they may contain, for example, hydrophilic agents, water repellents, etc. Water-based materials are preferred as the clear coat material. The clear coat material can, for example, form a matte finish.

[0058] For applying the clear coat material, methods such as spray application, roller application, and brush application can be used. The amount of clear coat material to be applied is preferably 0.03 to 0.5 kg / m². 2 More preferably 0.05 to 0.4 kg / m 2 The application or drying of the clear coat material may preferably be carried out at room temperature.
