Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel masonry pattern finishing method. Up until now, various methods of finishing with multicolored patterns and various paints used for them have been proposed, but granite,
There is currently no method to create high-quality stone patterns such as terrazzo stone using coating materials, as is the case with general painting methods. In the present invention, a mica mixture with a stone-like tone is created by suitably mixing flaky mica with a size of 1 to 10 mm colored in various colors by resin bonding dyes or pigments to mica pieces. When mixed with resin liquid or paint and then sprayed onto the material or onto the base coat formed on the material, these colored mica materials are arranged in layers on the surface, making it look like granite, terrazzo stone, etc. It was completed by discovering the formation of a stone pattern layer that exhibits an external appearance, and made it possible to create high-quality stone patterns such as granite and terrazzo stone using common painting methods. . The colored mica used in the present invention is in the form of flakes obtained by adhering dyes or pigments to ordinary mica flakes with a resin, and the size of the mica is 1 to 1.
The diameter is 10 mm, and 2 to 4 mm is particularly preferred. When this colored mica is mixed with a resin liquid or paint and applied by spraying, it has the property of forming layers on the surface, giving it the appearance of granite, terrazzo stone, etc. Mica may be colored in any desired color, but there are cases in which the unique color of mica is made more vivid, and cases in which it is colored in a color different from the color unique to mica. For example, hardening acrylic resins, melamine-alkyd resins, polyurethane resins, etc. are used as resins when dyes or pigments are bonded to mica, and silane coupling agents are used to improve adhesion. etc. are used. The dye or pigment attached to the mica piece through adhesive processing using such a curable resin will not dissolve into the solvent in the resin liquid or paint when the colored mica is mixed with the resin liquid or paint. It will not peel off from the mica pieces. For coloring, for example, titanium oxide, carbon black,
Cyanine blue is used, and these colored mica can be used depending on the type of resin liquid or paint to be mixed. In the present invention, the size is 1 to 1, as described above.
Colored mica of 10 mm is used, but this is because the crystals of high-grade stones such as granite are generally 1 to 10 mm, and if the size of colored mica is smaller than 1 mm, it is difficult to form a stone pattern like high-grade stones such as granite. If the size of the colored mica is larger than 10 mm, the pattern formed will differ from that of high-grade stone such as granite, and colored mica may be mixed with resin liquid or paint to contain colored mica. This is because when preparing the coating material, the colored mica is crushed unevenly, making it impossible to obtain a consistent stone pattern, and making it difficult to paint by spraying or the like. Stone patterns are created by painting with a coating material that is a mixture of colored mica and resin liquid or paint. After painting, if necessary, the painted surface is pressed with a roller or other pressing means to smooth out the unevenness of the painted surface, and then A clear paint or water repellent compounded to various gloss levels may be applied thereon. By doing so, the appearance and durability of the stone pattern layer are further improved. It is also possible to use a sanding sealer. In addition, before painting the above-mentioned colored mica-containing coating material, for example,
A design layer such as the main material (patterned sprayed material) of JIS A 6910 multilayer patterned sprayed material may be formed. Examples of resin liquids and paints to be mixed with colored mica include various emulsions, hydrosols, dispersions, water-soluble resin liquids, water-soluble paints, solvent-based resin liquids, various clear paints, transparent colored paints, and enamel paints. Liquids and paints are used. Specific examples of these include acrylic, styrene-acrylic or ethylene-vinyl acetate copolymer emulsions and hydrosols, alkyd, acrylated alkyd or acrylic dispersions, and water-soluble alkyd or acrylic dispersions. Examples include solvent-based acrylic, urethane, or epoxy resin liquids and paints. When mixing the colored mica and these resin liquids or paints, the amount of colored mica to the resin liquid or paint should be in a weight ratio of 1:99 to 40:60, particularly 5:95 to 30:70. is preferred. This is because if the amount of colored mica is too small, it will not be possible to create a sufficient masonry pattern, and if it is too large, it will be difficult to paint by spray or roller. The colored mica and the resin liquid or paint may be mixed immediately before painting, or may be mixed in advance. It is also possible to add other aggregates such as silica sand, ordinary mica, or plastic colorants when mixing the colored mica with the resin liquid or paint.
However, in that case, it is necessary that the total aggregate contains 20% or more (by weight, the same applies hereinafter) of colored mica, and it is particularly desirable that it contains 40% or more of colored mica. This is because if the amount of colored mica is small, a sufficient stone pattern cannot be created. Examples of materials include concrete, mortar, concrete mortar, slate, glass,
Various plastics, plywood, etc. are used. Glass and plastic can also be transparent,
In such cases, masonry patterns through glass or plastic may be the object. Before painting, it is desirable to prepare the material in advance by removing dust and dirt, and filling in cracks and chips. Painting materials containing colored mica may be applied directly onto the material, but after applying a primer coating material to the material,
It is preferable to do so. Examples of undercoating materials include those using solvent-based resin liquids such as chlorinated rubber, vinyl chloride resin, acrylic, chlorinated polyolefin, and moisture-curing urethane, and acrylic and ethylene-vinyl acetate. Transparent or pigment-colored sealers such as those using water-based resins such as copolymer systems and styrene-acrylic systems, and general colored paints such as acrylic systems, vinyl chloride resin systems, and chlorinated rubber systems are used. These primer coating materials can be applied using various methods such as spraying, rollers, and brushes, and the application amount is 100 to 200.
g/m ² is preferred. Application of colored mica-containing coating materials is carried out using a sprayer or a roller. One of the features of the present invention is that it can be applied by spray or roller in this way, thereby making it possible to efficiently finish high-grade masonry patterns such as granite and terrazzo stone.
The amount of coating is 300~3000g/ ^m2 , especially 1000~
The amount is preferably 2500 g/m ² , and when the material is to be prime coated, it is preferable to apply the coat after the base coat material has sufficiently dried. A stone pattern is created by coating this colored mica-containing coating material, but after the coating, it is preferable to press the coated surface with an appropriate pressing means to smooth out irregularities on the coated surface. In this case, a roller is usually used as the pressing means, and the roller is coated with paint thinner or water and rolled while lightly pressing the roller against the painted surface. Furthermore, the unevenness of the painted surface may be smoothed out by blowing compressed air onto the painted surface. Furthermore, if a clear paint or water repellent is applied as an overcoat to the stone pattern layer formed by painting with a colored mica-containing coating material, the appearance and durability of the stone pattern layer will be improved. Acrylic lacquers, urethane paints, acrylic emulsion paints, etc. are preferred, and as the water repellent, both silicone-based and non-silicon-based water repellents can be used, but non-silicon-based ones are particularly preferred. After applying the clear paint as a top coat, a water repellent may be further applied thereon. If a design layer is formed on the material or on the coating of the undercoat material applied to the material before applying the colored mica-containing coating material, the stone pattern will become three-dimensional and can have various shapes in appearance. It is preferable because it gives
The design layer at this time is formed by applying the main material used in the multilayer pattern sprayed material. Next, the present invention will be explained with reference to Examples. Example 1 Using a concrete mortar wall as the material, 120 g/m ² of X-coat R sealer (trade name, chlorinated rubber sealer, manufactured by Kawakami Paint Co., Ltd.) was applied to the concrete mortar using a roller, and the material was dried at room temperature for 2 hours. . Next, colored mica (a mixture of 85% white and 15% black,
Yamaguchi Mica Kogyo Co., Ltd.) 15 parts (parts by weight, the same applies hereinafter)
and 85 parts of X-coat clear (trade name, acrylic emulsion-based clear, manufactured by Kawakami Paint Co., Ltd.) and a colored mica-containing coating material was applied to the coating film of the X-coat R sealer using a mortar gun at a rate of 1500 g/m ^{2 .} Spray painted. The mortar gun used had a diameter of 5 mm, and the air pressure during spraying was 3.5 kg/cm ² . The size of the colored mica used was 3 mm for white and 4 mm for black. 30 minutes after painting, press the painted surface with a roller to smooth out any unevenness on the painted surface. After 24 hours, 80 parts of Ureol 800 Clear A liquid (trade name, acrylic polyol, manufactured by Kawakami Paint Co., Ltd.), 20 parts of Ureol No. 3B liquid (trade name, non-yellowing isocyanate curing agent, manufactured by Kawakami Paint Co., Ltd.) and Ureol No. 4 thinner (trade name, thinner for ureol 800, manufactured by Kawakami Paint Co., Ltd.). Mix and spray 250
g/m ² and dried for 24 hours at room temperature. In addition, when a stone pattern finish was applied to a concrete mortar board in the same manner as above, and the concrete mortar board was subjected to a weather-o-meter for 1000 hours,
There was almost no change in appearance, and no peeling of mica, cracks, or cracks in the coating were observed. Examples 2 to 9 Stone pattern finishing was performed according to the specifications shown in the following table. In both cases, a granite-like stone pattern was formed on the material. The colored mica used was the same as in Example 1, and the undercoat, colored mica-containing coating material, and top coat were applied in the same manner as in Example 1. Furthermore, the coating amounts of the undercoat and the colored mica-containing coating material were the same as in Example 1. The design layer was formed by spraying the acrylic emulsion base material used on the multilayer pattern spraying. When the material with the stone pattern finished in this way was put on a weather-o-meter for 1000 hours,
In all cases, there was almost no change in appearance, and no peeling of mica, cracks, or cracks in the coating were observed. 【table】
