Further, the present invention relates to a material that forms a color surface, a pattern surface, or a pattern surface by adhering dried and colored wood powder to an adhesive surface. Moreover, these color surfaces, pattern surfaces, or pattern surfaces can be used for simulated paintings, sand paintings, mosaic paintings, model toys, terrain models, and the like.

  Conventionally, as a granular paint, a water-soluble paste such as gum arabic, a porous material such as diatomaceous earth, or a pigment is used, and the pigment is adhered to the surface of the porous material such as diatomaceous earth. Is further adhered to the surface of a water-soluble paste such as gum arabic.

  The present applicant is also the applicant of the following patent document 1, and the invention according to the following patent document 1 is such that colored wood powder is pasted on the adhesive surface, and the texture of mosaic-like painting, granular painting, and dot-like drawing. It is said that it is made to give out.

JP 2006-130792 A Japanese Examined Patent Publication No. 61-55542 JP-A-56-122873 Japanese Patent Publication No.62-15111

  In the granular paint as described above, a material having two different sizes of two particles, ie, a water-soluble paste such as gum arabic and a porous substance such as diatomaceous earth is necessary, and many materials are required. . Therefore, water-soluble paste such as gum arabic may be omitted. However, in porous materials such as diatomaceous earth, the particle size is too small to produce a texture like a mosaic. .

  Moreover, in the invention which concerns on patent document 1, although wood powder has the effect | action which absorbs and decomposes a bad smell, since a coloring agent is made to adhere to the surface of this wood powder, the absorption and decomposition effect | action of this wood powder's bad smell will fall. There was a problem.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a colored wood powder manufacturing method, a colored wood powder, and a color capable of producing a texture like a mosaic image with a small amount of material. Is to provide a plane.

  In addition, the present invention does not reduce the malodor absorption and decomposition action of the wood powder even if a colorant is attached to the surface of the wood powder, the method of producing the colored wood powder, the colored wood powder, the color surface, and the pattern It is to provide a method for producing a surface or a pattern surface and a color surface, a pattern surface or a pattern surface.

  In order to achieve the above object, the present invention includes a step of attaching a colorant to wood powder, a step of attaching a photocatalyst to the wood powder of colored wood, and a tree to which the colored photocatalyst is attached. By attaching the powder to the adhesive surface, a color surface, a pattern surface, or a pattern surface was formed.

  As a result, even if a colorant is attached to the surface of the wood powder, the photocatalyst attached to the wood powder does not reduce the absorption and decomposition action of the malodor of the wood powder, and can strongly absorb and decompose the malodor and deodorize it. . Since the photocatalyst adheres to the surface of the fine particulate wood powder, the surface area where the photocatalyst is present increases, and it is possible to strongly absorb and decompose malodor and deodorize it. Moreover, since the wood powder to which the photocatalyst is attached is attached to the surface called the adhesive surface, the wood powder spreads in a planar shape, the surface area on which the photocatalyst is present increases, and it can strongly deodorize by absorbing and decomposing malodor.

  Further, the texture of the mosaic image can be obtained with a small amount of materials such as water or / and oil and colorant on the wood powder. Furthermore, the waste of large sawdust can be effectively used to make a recycled product, and a product that is good for the environment can be provided. Such large sawdust is produced by processing wood such as thinned wood.

(1) Manufacturing method of colored wood powder 3 The manufacturing method of colored wood powder 3 is as follows. In terms of weight ratio, 10 to 100 parts by weight of wood flour 5 (including large saw dust, the same applies hereinafter) and 1 to 100 parts by weight of colorant are mixed with 100 parts by weight of water or / and oil. Further, in the volume ratio, 50 to 400 parts by volume of wood flour and 5 to 100 parts by volume of colorant are mixed with 100 parts by volume of water or / and oil.

  Desirably, 50 parts by weight of wood flour and 50 parts by weight of colorant are mixed with 100 parts by weight of water or / and oil. Further, in a volume ratio, 200 parts by volume of wood flour and 5 to 25 parts by volume of colorant are mixed with 100 parts by volume of water or / and oil.

  More preferably, in a weight ratio, 75 parts by weight of wood flour and 3.75 parts by weight of a coloring agent in a dry state are mixed with 100 parts by weight of water or / and oil. Since the wood powder 5 contains a lot of air, the specific gravity is reduced to 2/3 to 1/4 of the specific gravity of the original wood of the wood powder 5. As the colorant 6, a food colorant, a pigment or a paint is selected.

  The above mixture is thoroughly stirred using a stirrer or a stirring bar, and water or / and oil and the colorant 6 are uniformly mixed with the wood flour 5. When mixed with water, the colorant 6 is aqueous, and when mixed with oil, the colorant 6 is oily and when mixed with water and oil mixture The colorant 6 is water-based or oil-based or a mixture thereof, and a surfactant or the like is mixed in order to promote uniform mixing of water and oil.

  By such mixing, the particles of the colorant 6 adhere to the gaps between the wood powder 5 of the wood and the wood powder 5 is colored. The particle size of this wood flour 5 (large sawdust) is 0.1 to 5 millimeters, optionally 0.5 to 2.5 millimeters, for example 1.0 to 2.0 millimeters, for example 1.5 millimeters. is there. The gaps in the wood powder 5 are gaps between the coniferous temporary canal or the hardwood tree fibers, and this gap is usually 1 μm to 50 μm. Conifers are, for example, cedar, cocoons, pine, cocoons, etc., and hardwoods are cocoons, cocoons, chestnuts, peaches, cocoons, paulownia, etc.

  The wood powder 5 colored as described above is completely dried or dried to some extent, and then the photocatalyst paint is sprayed in the form of a mist while being stirred in a sealed container. This stirring is performed by one or a plurality of screw-shaped or tapered screw-shaped stirring rods, a bowl-shaped stirring ridge provided in the sealed container, rotation of the sealed container itself, air blown from a blower, or the like. .

  The photocatalyst paint is a paint containing a photocatalyst 7 such as titanium oxide such as titanium dioxide, and it is desirable that the photocatalyst paint is made of a harmless component that can be put into the mouth or into the body. Of course, depending on the application, it may consist of components that are harmless in skin contact. Many kinds of such photocatalytic coatings are commercially available.

  Such photocatalyst 7 has a weight ratio of 10 to 100 parts by weight of the above-described wood flour, and 0.5 to 15 parts of titanium dioxide when it is not white, and 1.2 to 36 parts of titanium dioxide when it is white. In both parts and volume ratios, 0.1 to 50 parts by volume of titanium dioxide is attached to 50 to 400 parts by volume of the wood powder described above, and 0.24 to 120 parts by volume when white, except for white. .

  Desirably, with respect to 50 parts by weight of the above-mentioned wood flour, 2.5 parts by weight of titanium dioxide when it is not white, 6.0 parts by weight of titanium dioxide when it is white, When the volume is other than white, 1 volume part of titanium dioxide is attached to the volume part, and 2.4 parts of titanium dioxide are attached when white. More preferably, 3.75 double parts of titanium dioxide adhere to 75 parts by weight of the above-mentioned wood flour, and 9.0 double parts of titanium dioxide when white.

  Thus, the amount of titanium dioxide mixed when the wood powder 5 is colored white is larger than the amount of titanium dioxide mixed when the colorant 6 other than white is attached to the wood powder 5. Thereby, the white coloring agent 6 becomes unnecessary. Of course, a white colorant 6 may be used.

(2) Particle diameters of the wood powder 5, the colorant 6 and the photocatalyst 7 The particle diameter of the wood powder 5 is 0.1 to 5 millimeters, desirably 0.5 to 3.5 millimeters, and more desirably. 1 to 2 millimeters. The colorant 6 has a particle size of 10 to 1000 micrometers, preferably 50 to 500 micrometers. The particle size of the photocatalyst 7 is 10 to 1000 nanometers, preferably 50 to 500 nanometers.

  FIG. 1 shows an enlarged view of the colored wood powder 3 to which the photocatalyst 7 is attached. The particle size of the photocatalyst 7 and the colorant 6 is smaller than the particle size of the wood powder 5, and the particle size of the photocatalyst 7 such as titanium dioxide is smaller than the particle size of the colorant 6. As a result, a large amount of the colorant 6 adheres to the surface of the wood powder 5 and a large number of photocatalysts 7 such as titanium dioxide can adhere to the surface of the colorant 6. The photocatalyst 7 is not sandwiched between the wood powder 5 and the colorant 6, the colorant 6 does not adhere to the surface of the photocatalyst 7, and the action of decomposing and deodorizing the bad odor of the photocatalyst 7 is reduced. Therefore, the function of the photocatalyst 7 is sufficiently exhibited.

  This is because the photocatalyst 7 is adhered after the colorant 6 is adhered to the wood powder 5, so that the photocatalyst 7 is not sandwiched between the wood powder 5 and the colorant 6, and the function of the photocatalyst 7 is more fully exhibited. The If the photocatalyst 7 such as titanium dioxide adheres to the surface of the colorant 6, the color of the whole wood powder is slightly white and changes in brightness and saturation, but this can be solved by increasing the amount of the colorant 6. In view of this, the mixing amount of the colorant 6 is determined as described above.

  The wood powder 5 is manufactured in the following steps. First, large sawdust of thinned wood is first passed through a “sieve” with a 2 mm square mesh, and large sawdust with a particle size exceeding 2 mm is excluded. Next, the large sawdust having a particle size of 2 mm or less dropped from the 2 mm “sieving” is applied to the “sieve” having a mesh size of 1 mm, and the large sawdust having a particle size of 1 mm or less is excluded. The large sawdust with a particle size of 1.1 mm to 1.9 mm and a particle size of 1.5 mm remaining in the 1-millimeter “sieve” is used for the coloring and titanium dioxide deposition.

  When the particles of the colorant 6 become smaller, the color of the wood powder 5 becomes lighter and the color of the tree becomes stronger. When the particles become larger, the color of the wood powder 5 becomes darker and the color of the tree becomes weaker. By drying the water or oil of the mixture, the adhesion / penetration of the dried product or solid particles of the colorant 6 to the wood powder 5 is fixed, whereby the wood powder 5 is colored. The wood powder 5 such as large saw dust is very easy to adhere the coloring agent 6.

  The particle size of the colorant 6 may be 10 to 1000 nanometers, the particle size of the photocatalyst 7 may be 10 to 1000 micrometers, and the particle size of the colorant 6 may be smaller than the particle size of the photocatalyst 7. Thereby, the coloring agent 6 adheres to the surface of the photocatalyst 7, and a vivid color can be emitted. In this case, a step of attaching the colorant 6 to the wood powder 5 may be performed after the step of attaching the photocatalyst 7 to the wood powder 5.

  The particle diameter of the colorant 6 and the particle diameter of the photocatalyst 7 are 10 nanometers to 1000 micrometers, and the particle diameter of the colorant 6 and the particle diameter of the photocatalyst 7 may be the same. Thereby, the action of decomposing and deodorizing the bad odor of the photocatalyst 7 is not lowered to some extent, and a vivid color can be produced to some extent. In this case, the step of attaching the colorant 6 to the wood powder 5 and the step of attaching the photocatalyst 7 to the wood powder 5 may be performed simultaneously.

  In this way, the adhesion of the colorant 6 and the adhesion of the photocatalyst 7 are performed simultaneously using the oily colorant 6, and the wood powder 5, the colorant 6 and the photocatalyst paint or powder photocatalyst 7 are well mixed in the oil. Thereafter, the colored wood powder 5 to which the photocatalyst 7 is attached is dried. In addition, water-based colorant, water-based photocatalyst paint, and wood powder 5 are mixed well in water, and then the photocatalyst 7 is adhered and the colored wood powder 5 is dried.

  Furthermore, the photocatalyst paint and the liquid colorant are simultaneously sprayed in the form of a mist while the wood powder 5 is stirred in the sealed container. If some of these components are aqueous and others are oily, a surfactant is optionally mixed.

(3) Coloring agent 6
The colorant 6 is a food colorant. The food colorant is a natural food colorant, an artificial food colorant, a food additive colorant, or the like, and the following materials are used for each color.
(1) Black: Natural ink (oil smoke ink)
(2) Red: pigment obtained from Benikouji (3) Blue: pigment extracted from seaweed such as spirulina or seaweed (4) Green: food additive colorant formulation (5) yellow: pigment extracted from gardenia fruit (6) Brown: pigment extracted from gramineous grains (7) Purple: pigment extracted from domestic purple potato (8) Brown: pigment mixed with gardenia yellow and blue (9) white: achieved by adhesion of titanium dioxide .

  These are examples, and other food colorants may be used. By using such food coloring, it is safe and harmless if a disabled person or a person with dementia licks or puts it in the mouth by mistake. Two or more of these food colorants may be mixed to create another color.

  In addition, as the colorant 6, poster colors, watercolor paints, oil paints, etc. are used. Titanium oxide, zinc white, carbon black, Hansa Yellow G, Hansa Yellow G, ocher, hand sienner, Bengala, Laked, Carmine 3B, ultramarine It consists of ingredients such as phthalocyanine blue, chrome green and iron oxide.

  The colorant 6 includes an organic pigment and an inorganic pigment. As such an actual product, the black color of the poster color of Pentel Corporation. 28, dark green no. 74, grass color no. 63, yellowish green 17, Viridian no. Products with numbers such as 18 are used.

  The colorant 6 has many colors such as white, black, gray, blue, red, yellow, green, purple, orange, a mixed color thereof, gold, silver, copper, and pearl. In addition, when the wood powder 5 colored in this way is mixed with different colors, the color / pattern / pattern in which the mixed colors are visible in the distance and the particles of the wood powder 5 are visible in the near eye. Can be formed.

  When the wood powder 5 is colored white as in (9) above, the titanium dioxide also serves as the white colorant 6, and the colorant 6 is not used. Of course, a white colorant 6 may be used. The amount of titanium dioxide mixed when the wood powder 5 is colored white is larger than the amount of titanium dioxide mixed when the colorant 6 other than white is attached to the wood powder 5.

  Since titanium dioxide is also mixed with the colorant 6 of other colors, the colors other than the white colors in the above (1) to (8) have saturation and lightness containing a little white titanium dioxide. In order to produce the same brightness and saturation for white as other colors, it must be “titanium dioxide (photocatalyst) + white colorant”, but “white colorant” is “titanium dioxide”. As a result, for white, the amount of titanium dioxide increases as compared to other colors.

  As described above, the step of mixing titanium dioxide with wood powder 5 and adhering it to wood powder 5 is performed separately. In addition, after the step of adding and mixing the wood powder 5 to the colorant 6 mixed / dissolved in water and attaching it to the wood powder 5, a step of attaching the photocatalyst paint or photocatalyst powder to the wood powder 5 is performed. Thereby, the coloring agent 6 does not adhere to the surface of the titanium dioxide, the function of decomposing and deodorizing the malodor of the titanium dioxide is not lowered, and the function of the photocatalyst 7 is sufficiently exhibited.

  Conversely, after the step of attaching the photocatalyst paint or photocatalyst powder to the wood powder 5, the step of adding and mixing the wood powder 5 to the colorant 6 mixed and dissolved in water and attaching it to the wood powder 5 is performed. May be. Thereby, the coloring agent 6 adheres to the surface of the photocatalyst 7 such as titanium dioxide, and a vivid color can be obtained.

  Further, the step of mixing the colorant 6 with the wood powder 5 and adhering it to the wood powder 5 and the step of adhering the photocatalyst paint or photocatalyst powder to the wood powder 5 may be performed together. Thereby, the process for producing the colored wood powder 3 can be reduced. The method of performing both of these steps together has been described above.

The above mixture, optionally in addition of the above-mentioned surfactants, optionally mixed with alcohol. The surfactant may be any of cationic surfactants, anionic surfactants, nonionic surfactants, amphoteric surfactants, and nonionic surfactants such as polyoxyethylene glycol ethers and polyoxyethylene glycol ethers. A surfactant is selected.

  The alcohol may be any of a primary alcohol, a secondary alcohol, a tertiary alcohol, a lower alcohol, a higher alcohol, an alicyclic alcohol, an aromatic alcohol, etc., and an aliphatic monohydric alcohol or the like is selected.

  Drying of the water or oil after coloring or drying of the wood powder 5 after the photocatalyst 7 is adhered is not only natural drying for one day or several days, but also drying by heating with a heater for several hours, drying by feeding dry air. There are air blowing drying, heating air blowing drying in which warm air is blown, and the like. In such air drying, the mixture is stored in a container so that the colored wood powder 3 does not scatter.

  As the oil, tempura oil, salad oil, olive oil, rapeseed oil, soybean oil, oil for oil paint, petroleum, petroleum-based solvent, and the like are used, and those having high volatility are optimal for the drying. However, because of the danger of ignition, oil with a high flash point / ignition point is used.

(4) Method for Manufacturing Color Surface, Pattern Surface, or Pattern Surface FIG. 2 shows a method for manufacturing a color surface, pattern surface, or pattern surface. The colored wood powder 3 to which the titanium dioxide is attached is produced in a plurality of colors by the method for producing the colored wood powder 3. A double-sided adhesive tape is bonded to the surface of a plate, metal plate or paper to form an adhesive surface 1. A mask sheet 2 is adhered and covered on the upper adhesive surface of the adhesive surface 1.

  The mask sheet 2 is divided into a plurality of portions, and the plurality of mask sheets 2 are sequentially peeled off. Each time this mask sheet 2 is peeled off, colored wood powder 3 of any color is sown over it, and the colored wood powder 3 is pressed against the adhesive surface 1 by hand, horse, soft roller or hard roller. The colored wood powder 3 is attached to the bonding surface 1.

  In this case, if a double-sided adhesive tape using a urethane sheet is used as the adhesive surface 1, the adhesive layer on the adhesive surface is thin, so that a colored wood to which titanium dioxide is adhered is used compared to the case where a fluid adhesive is used. Since the powder 3 does not sink into the adhesive layer and is not buried, the malodor decomposition action of the titanium dioxide of the colored wood powder 3 is not reduced.

  The remaining colored wood powder 3 not adhered is removed with a brush or a small broom, and returned to the original colored wood powder 3 container of the same color. Therefore, the colored wood powder 3 is used effectively without waste.

  The above operation is repeated for the colored wood powders 3 of each color, and each time the mask sheet 2 is peeled off, the colored wood powders 3 of any color are sequentially attached, whereby a plurality of colors or multicolor colors are obtained. A surface (pattern surface or pattern surface) 4 is formed.

Therefore, it is possible to draw a multi-color / multi-color color surface, a pattern surface, and a design surface so that the colored wood powders 3 of the respective colors are not mixed with each other.

  When adhering such colored wood powder 3, two or more kinds of different colors are mixed and pasted onto the adhesive surface 1. When these are mixed colors on the far side, the particles of wood powder 5 for each color are on the near side. A color surface / pattern surface / picture surface can be formed. For example, when green and yellow colored yellow powder are mixed and pasted on the adhesive surface 1, it looks like a yellowish green leaf with a fresh green leaf in the distance, and looks like a mottled plant with a mixture of yellow and green in the near eye. .

  In this case, when the mixing ratio of each colored yellow powder 3 to be mixed is changed, it can be changed between yellow and green from green close to yellow to yellow close to green. This is the same for a plurality of combinations of colored wood powder 3 of other colors, and even when three or more colors are mixed, a change between three colors, a change between four colors,... The above color change can be changed in multiple ways.

  Thereby, the color surface, pattern surface, or picture surface of various mixed colors is formed. Such a color surface, a pattern surface, or a pattern surface has a mosaic shape, a grain shape, a point drawing shape, or the like. Then, it is possible to draw a multi-color / multi-color color surface, a pattern surface, and a design surface so that the colored wood powder 3 of each color is not mixed with each other.
