Description

TECHNICAL FIELD The present invention relates to colored paper powder for modeling, which is used for producing dioramas and the like.

A diorama, also called a scene model, is an exhibition model that realistically expresses a townscape, landscape, or people's lifestyles in a reduced scale. In recent years, it has been gaining popularity for its elaborate reproductions of famous buildings from around the world, as well as realistic reproductions of the scenery of the Showa era, centering on model railroads. There are also many enthusiasts who create elaborate dioramas. The so-called sandplay can also be called a kind of diorama in general, although it depends on the object that it represents.

In addition, making simple dioramas is considered to be a form of self-expression similar to drawing and clay work, and there are examples of it being incorporated as part of early childhood education and dementia prevention measures for the elderly. Exquisite dioramas made by craftsmen and enthusiasts, such as the examples given above, are displayed and appreciated over a long period of time as a work of art. When the diorama is used, the production process itself is more important than the appreciation of the produced product, so the produced diorama is discarded in a relatively short period of time (after taking photographs if necessary). often

When expressing mountain surfaces, trees and grasslands in a diorama, or expressing ballast on gravel roads and railroad tracks, conventionally, colored granular sponge material called turf, natural sand grains, foliage or They also used sheets of turf called a foliage cluster, or turf that was combined in a mass.

Turf and sand grains have excellent corrosion resistance and weather resistance, so they are suitable for making dioramas that will be exhibited for a long period of time. Since it is made, it is somewhat difficult to incinerate it at the time of disposal. In addition, turf is a special material developed from the beginning for the production of dioramas (especially elaborate ones intended for exhibition), so it is expensive to use for repeated production and disposal of simple dioramas. becomes.

In order to solve the above-described problems, the present invention provides a set of colored paper powder for modeling that has a desired color with an adjusted particle size range, a set of powdered modeling paper that has a different particle size range or different colors, and a method for producing the same. It provides

According to the colored paper powder for modeling of the present invention, by using paper powder having a particle size range and color selected according to the object to be expressed, anyone can easily produce a diorama or the like. Disposal of the diorama or the like that has been made can also be easily performed by incineration or the like. In addition, the colored paper powder for modeling of the present invention is made from industrial waste and is inexpensive, so it is suitable for teaching materials that are repeatedly manufactured and discarded.

<Colored paper powder for modeling>
The raw material of the colored paper powder for modeling of the present invention is paper powder. Paper dust is dust composed of pulp fibers, fillers, pigments, etc. generated during paper making, cutting, processing, and the like. If paper dust adheres to the surface of the printing paper, it can be transferred to the rollers of the printing press or the plate surface and cause white spots on the printed matter. Therefore, remove the paper dust from the surface of the paper before printing. Special mats are also available for sale. In addition, when manufacturing paper containers (corrugated cardboard boxes for storage and transportation, cosmetic boxes as product packaging containers, etc.) by cutting and folding sheet-shaped cardboard and paperboard, the Since the adhering paper dust is removed, a large amount of the removed paper dust is generated as industrial waste and disposed of by incineration or the like.

Paper dust generated when corrugated board and paperboard are processed into paper containers contains foreign matter such as relatively large shavings and fibrous fragments (called "whiskers" in the industry). The grain size (the grain size of each grain taken in the direction of the maximum length) is about 0.1 to 5 mm. The particle size of the powder used in the production of the diorama depends on the size of the diorama and the object to be expressed, but it is usually about 0.1 to 2 mm, so the paper powder of the above size is appropriately adjusted according to the object to be expressed. If sieving (removal of large particles, etc.), it is quite possible to use it for diorama production. On the other hand, the particle size range of paper dust generated when copying paper is cut is on the smaller side, usually about 0.05 to 0.3 mm, but such fine paper dust can be expressed more finely. may be used.

For example, when producing a diorama with a scale of about 1/80, 1) powder with a particle size of about 2 to 6 mm is used to express mountain surfaces and large stones, and 2) grains are used to express roadside grasslands and dry grass. Powder with a diameter of about 0.2 to 2 mm, and 3) powder with a diameter of about 0.2 to 0.5 mm are often used to express gravel laid on roads and railroad tracks. Therefore, it is sufficient to obtain paper powder suitable for these uses by sieving raw paper powder from which foreign matter has been removed.

As described above, the powder for modeling paper of the present invention is sifted into a desired particle size range suitable for its use and colored in a desired color suitable for its use. In general, the powder for use 1 above is gray-black to dark brown, the powder for use 2 is yellowish-brown to yellow-green, and the powder for use 3 above is grayish-white. I hope it is. For example, even if you want to express the surface of a mountain, if you want to express a cliff with so-called rocks exposed, it would be better to paint it in a gray color that is close to black, and red or black soil is exposed. If you want to express a place that looks like it's growing, it's better to use a dark brown color. would be good It should be noted that the coloring of the modeling paper powder of the present invention does not necessarily have to be uniform, and in some cases it is preferable to have some unevenness. Also, by mixing paper powder of different colors, it is sometimes possible to express deep colors and complex colors.

By the way, what kind of color the paper powder should be colored is a matter of expression, so it cannot be uniformly decided. In particular, it would be extremely difficult to unify the color of the paper dust for each object to be represented in advance if it is used in a diorama that is produced in earnest as a work of art. Since such a diorama should basically have individuality for each work, the diorama maker should adjust the colors based on his own sensibility. However, if the colored paper powder for modeling of the present invention is to be used as a teaching material for diorama production, for example, for early childhood education or cognitive prevention training for the elderly, standard colors should be prepared for each purpose to some extent. Let's do it. Of course, it is assumed that the colored paper powder for modeling of the present invention is also used for the former (production of a diorama for viewing as a work of art), but if anything, it is more likely to be used for the latter (production of a diorama for educational or training purposes). ) is primarily intended to be used for

<Production of colored paper powder for modeling>
FIG. 1 shows an example of the steps for producing the colored paper powder for modeling of the present invention. In the first step (a), foreign substances such as cut waste and fibrous fragments (whiskers) mixed in the raw paper powder are removed. As a raw material, as described above, paper powder generated during the processing of corrugated board or paperboard is preferably used. This is because it contains cut shavings and whiskers generated when inserting or bending. In order to remove such foreign matter, sieving may be performed using a coarse sieve (for example, a sieve with an opening of about 5 to 10 mm).

FIG. 2 shows an example of a sieving device (rotary old soil separator called a rotor sieve) that can be used for such foreign matter removal. The apparatus shown in FIG. 2 consists of a replaceable sieve with a mesh 2 of various meshes stretched in a circular frame 1 and a scraper 3 rotatable so as to stroke the top surface of the mesh. When the powder is placed and the scraper is rotated by the handle 4, when the raw paper powder moves on the net, the paper powder itself, which is a particle smaller than the mesh, passes through the mesh and falls down. The shavings and fibrous fragments contained as foreign matter in the raw paper powder remain on the net. Therefore, by collecting the paper dust that has passed through the mesh and fallen down, the raw paper dust from which the foreign matters have been removed can be obtained. In addition to the standard mesh (12.6 mm short diameter x 25.2 mm long diameter) that comes with the main body, the rotor sheave has a smaller mesh size (8 mm short diameter x 16 mm long diamond) that is sold separately as a spare mesh. meshes) and fine meshes (rhombic meshes with a short diameter of 5 mm and a long diameter of 10 mm) can be attached, and foreign matter in the raw paper powder can be removed by using a mesh with an appropriate mesh size.

The raw paper powder from which the foreign matter has been removed is then adjusted to have a desired particle size range. For this purpose, the apparatus shown in FIG. 2 or another sieving apparatus can be used, and sieving can be performed using two types of screens with different openings corresponding to the upper and lower limits of the particle size range. In the shown rotor sieve, the finer mesh is the finer mesh, so if it is desired to obtain paper powder having a finer upper or lower size limit, it is necessary to prepare a sieve with a smaller mesh size. That is, as shown in FIG. 3A, the raw paper powder from which foreign substances have been removed is first placed on a sieve with a mesh capable of removing paper powder having a size exceeding the upper limit of the desired particle size range, and then sieved. Then, as shown in FIG. 3(b), the paper dust that has passed through the mesh and fallen is collected. Subsequently, as shown in FIG. 4, the screen is changed to a mesh with openings that allow paper dust smaller than the lower limit of the desired particle size range to pass through, and the paper dust remaining on the mesh is sieved in the same manner. is, in principle, paper dust with the desired particle size range.

However, when sieving is performed as described above, all paper powder particles with a particle size larger than the sieve mesh remain on the sieve mesh, but paper powder with a particle size smaller than the sieve mesh Since not all particles pass through the mesh, it is unavoidable that the paper powder adjusted to the desired particle size range (should be) contains a certain amount of paper powder particles smaller than the desired particle size range. However, what is important in paper dust for diorama production is the upper limit of the particle size range, and the inclusion of paper dust particles smaller than the lower limit of the particle size range is basically no problem. This is because the paper dust particles are not perfectly spherical but have an irregular shape. This is because it adheres to and integrates with the large-sized paper powder particles, and becomes part of the surface shape of the large-sized paper powder particles. For example, even if the paper powder adjusted to the desired particle size range for Application 1 representing mountain rocks and large stones contains some paper powder particles smaller than the lower limit of the desired particle size range, There is almost no sense of discomfort when actually used, and it can be used sufficiently suitably for the purpose. That is, in the present invention, the adjustment of the particle size range of the sifted paper dust allows the inclusion of particles smaller than the lower limit of the range to some extent.

The paper powder adjusted to have the desired particle size range is then colored to the desired color. To color paper powder, various coloring agents (dyes, pigments, etc.) are dissolved or suspended in water or a mixed solvent of water and a hydrophilic organic solvent (e.g., ethanol). can be used as a coloring liquid. Since the raw material of the colored paper powder for modeling of the present invention is so-called "paper", ink for printing on paper (for example, ink for inkjet printers) is preferably used as such "ink". Specifically, as shown in FIG. 5, paper powder to be colored is placed in a container and stirred while adding a coloring liquid. The concentration and addition amount of the coloring liquid may be determined as appropriate, but when using a commercially available inkjet printer ink, the ink diluted about 5 to 10 times with a mixture of water and ethanol is used as the coloring liquid. Coloring liquid may be added in an amount equal to the amount of paper powder while observing the situation. After the coloring process, the coloring liquid is drained, the sheet is spread on the sheet for about 2 to 3 days, and air-dried to obtain colored paper powder as shown in FIG.

A set of colored paper powders for modeling can be obtained by individually packaging the colored paper powders having different particle size ranges and colors, which are produced as described above, into a set. For example, different colored paper powders to be expressed may be separately packaged and set, or a plurality of colored paper powders having different particle size ranges and colors may be appropriately mixed and used to express a certain expression object. If you can do it, you will be able to demonstrate the individuality of the diorama maker.

<Production of a diorama using colored paper powder for modeling>
To make a diorama, first make a base. Normally, the base of a diorama is often formed by using clay or plaster on a flat wood plate such as plywood (flat base) to form the shape of the ground. Instead of using uncolored paper powder as a raw material for the colored paper powder of the present invention, it is also possible to form the shape of the ground. In addition, when the shape of the ground is formed using uncolored paper powder, it is preferable to reinforce the surface by covering the surface with a fine-mesh net so that the surface does not collapse.

The ground is then colored. When the shape of the ground is made with clay or gypsum, the ground part of the surface is painted with acrylic paint, etc., but when the shape of the ground is made with uncolored paper powder, it is colored in a color close to the ground. You can express the color of the ground by spreading paper dust. In this case, the color unevenness of the ground surface may be expressed by mixing and spreading colored paper powder of different colors. For example, if the ground is soil, use brown colored paper powder, if there are many stones, mix gray colored paper powder, and if there are weeds, use grass-colored (greenish yellow) colored paper powder. It is possible to express the color of each ground by mixing and spreading, and by mixing and spreading yellow-brown colored paper powder in areas with a lot of dry grass.

Slopes of mountains and the like can be similarly colored. In order to express the slope of a mountain covered with trees, it is better to use a mixture mainly composed of greenish-yellow colored paper powder that is relatively large in size compared to grassland, etc., and arrange it on the slope. In addition, places where cliffs and large rocks are exposed can be expressed by mixing dark brown colored paper powder with large grain gray colored paper powder and laying them out. In the past, coasters and foliage were used to express trees, and sand and stones were used to express rocks. You can express these things without using .

In order to express the river, conventionally, light blue transparent resin was used, or the base was colored with paint, etc., but when using the colored paper powder of the present invention, blue that imitates the color of water is used. It can be expressed by spreading the colored paper powder of the system. Also, in order to express the appearance of blooming flowers, conventionally, a diorama sheet expressing flowers was pasted, but when using the colored paper powder of the present invention, it is possible to create a flower of your choice. It can be expressed by scattering colored paper powder that imitates color.

In addition, when a diorama is produced using the colored paper powder of the present invention, it is preferable to finally sprinkle spray glue on the diorama to harden it. FIG. 7 is a photograph showing an example of a diorama made using the colored paper powder of the present invention.

(Example 1) Manufacture of colored paper powder expressing rocks and large stones Paper powder to be discarded provided by Konno Packing Co., Ltd. was used as raw material paper powder. This raw material paper powder is separated by a manual rotary old soil sorter equipped with a standard mesh mesh (12.6 mm × 25.2 mm rhomboid mesh, mesh opening of about 11 mm) attached to the main body (trade name “Mawaru Sieve Rotor Sieve”, (manufactured by Kobayashi Kanamono Co., Ltd.) and sieved to remove foreign matter such as cut shavings and fibrous fragments. The raw paper powder from which the foreign matter was removed had a wide range of particle diameters of about 0.1 mm to 10 mm, so it was changed to a mesh with a medium mesh (8 mm × 16 mm diamond mesh, opening of about 7 mm). By sieving again with a sieving machine, paper dust particles having a particle size exceeding 6 mm were removed. Furthermore, by sieving this with a commercially available gardening sieve (opening about 2 mm) to drop most of the paper powder particles with a particle size of less than 2 mm, the paper powder particles with a particle size range of about 2 mm to 6 mm I got a lot of paper dust.

Next, the paper powder obtained above was collected and placed in a circular container, and commercially available inkjet printer inks (gray and black) were diluted with water and ethanol (1:1 mixture) and mixed to obtain grays of various brightnesses. The inks were prepared, and while adding these gray inks to the container little by little, the paper powder was stirred with a hand mixer and hand kneading to color grayish white to grayish black until the desired color was obtained. Once the paper powder was colored to the desired shade, it was spread on a blue sheet and allowed to dry for 2 days avoiding direct sunlight. In addition, since the color of the paper dust becomes lighter after drying completely than immediately after coloring, the coloring was carried out taking this fact into consideration. Also, when using a hand mixer, the paper dust is dispersed well, and when kneading by hand, the paper dust tends to stick to each other and harden, so using this, fine gravel and large rocks can be made separately. was made.

(Example 2) Production of colored paper powder representing exposed soil Using the same raw paper powder as in Example 1, the particle size range was adjusted in the same manner. However, as a replacement net for sieving paper powder from which foreign substances have been removed, a fine mesh (5 mm × 10 mm rhomboid mesh, opening of about 4 mm) is used instead of medium mesh, and the particle size is large enough to exceed 3 mm. Particle size paper dust particles were removed. Further, the removal of fine paper dust particles, which was carried out in Example 1, was not carried out. Various shades of reddish brown (dark brown) obtained by mixing paper powder with a particle size range of about 0.2 to 3 mm obtained in this way using commercially available ink for inkjet printers (mainly magenta and yellow, with a little cyan and gray). Colored paper powder was obtained by coloring and drying in the same manner as in Example 1. In addition, only stirring with a hand mixer was performed for stirring at the time of coloring, and hand kneading was not performed.

(Example 3) Production of colored paper powder representing weeds in roadsides and vacant lots Using the same raw paper powder as in Example 1, the particle size range was adjusted in the same manner. However, as a replacement net for sieving paper powder from which foreign matter has been removed, a fine mesh (5 mm × 10 mm diamond mesh, opening of about 4 mm) is used instead of medium mesh, and paper with a particle size exceeding 3 mm Dust particles were removed. Furthermore, most of the paper powder particles having a particle size of less than 1 mm were dropped by sieving with a commercially available horticultural sieve (opening of about 1 mm). The resulting paper powder having a particle size range of about 0.5 to 3 mm was mixed with commercially available inkjet printer inks (mainly cyan and yellow, with a little gray), and various greenish-yellow colored liquids were used. Coloring and drying were carried out in the same manner as in 1 to obtain colored paper powder. In the same manner as in Example 1, at the time of coloring, agitation with a hand mixer and hand kneading were used in combination to give variation in size.

(Example 4) Production of colored paper powder representing dry grass Using the same raw paper powder as in Example 1, the particle size range was adjusted in the same manner. However, as a replacement net for sieving paper powder from which foreign matter has been removed, a fine mesh (5 mm × 10 mm diamond mesh, opening of about 4 mm) is used instead of medium mesh, and paper with a particle size exceeding 3 mm Dust particles were removed. Furthermore, a part of the paper powder particles having a particle size of less than 1 mm was dropped by lightly sieving with a commercial gardening sieve (opening of about 1 mm). Paper powder with a particle size range of about 0.2 to 3 mm obtained in this way is mixed with commercially available inkjet printer ink (mainly cyan and yellow, with a little magenta) to give various shades of yellowish brown to greenish brown. The liquid was colored and dried in the same manner as in Example 1 to obtain colored paper powder of various shades. For coloring, only a hand mixer was used for stirring, and the color saturation was suppressed by avoiding mixing of multiple colors.

(Example 5) Production of colored paper powder representing flowers Using the same raw paper powder as in Example 1, the particle size range was adjusted in the same manner. However, as a replacement net for sieving paper powder from which foreign matter has been removed, a fine mesh (5 mm × 10 mm diamond mesh, opening of about 4 mm) is used instead of medium mesh, and paper with a particle size exceeding 3 mm Dust particles were removed. Furthermore, most of the paper powder particles having a particle size of less than 1 mm were dropped by sieving with a commercially available horticultural sieve (opening of about 1 mm). The resulting paper powder having a particle size range of about 0.5 to 3 mm was mixed with commercially available inkjet printer inks (cyan, yellow, and magenta) without multi-color mixing. Coloring and drying were carried out in the same manner as in , to obtain colored paper powder with various vivid shades. In the same manner as in Example 1, at the time of coloring, agitation with a hand mixer and hand kneading were used in combination to give variation in size.

(Example 6) Production of colored paper powder representing a river Using the same raw paper powder as in Example 1, the particle size range was adjusted in the same manner. However, as a replacement net for sieving paper powder from which foreign matter has been removed, a fine mesh (5 mm × 10 mm diamond mesh, opening of about 4 mm) is used instead of medium mesh, and paper with a particle size exceeding 3 mm Dust particles were removed. Furthermore, most of the paper powder particles having a particle size of less than 1 mm were dropped by sieving with a commercially available horticultural sieve (opening of about 1 mm). The paper powder thus obtained having a particle size range of about 0.5 to 3 mm is colored in the same manner as in Example 1 with a coloring liquid prepared using a commercially available inkjet printer ink (mainly cyan, with a little gray and magenta). And drying was carried out to obtain colored paper powder exhibiting a light blue color. The fineness of the water was expressed by only stirring with a hand mixer during the coloring process.

(Example 7) Production of Diorama Using Colored Paper Powders for Modeling Using the colored paper powders produced in Examples 1 to 6, they were separately packaged to form a set of colored paper powders for modeling. When using this set to express a vacant lot with large rocks scattered about and partly covered with weeds, we were able to create a realistic vacant lot. For the portion where light is reflected on the surface of the water, the colored paper powder of Example 6 mixed with white was used as an accent color. FIG. 7 is a photograph of the produced diorama, albeit in black and white.
