First, the raw material mixture will be described individually.

Examples of charcoal include wood, bamboo, fruit such as palm fruit or its skin, husks such as rice husks, oat husks, plant-based carbides such as plant residues such as sugarcane meal, animal-based carbides such as bones, and coal , Lignite, coke, petroleum pitch and other minerals, synthetic resin such as phenolic resin and acrylonitrile resin, synthetic rubber, natural rubber and other rubber carbide, coconut charcoal and activated carbon Can be Any of these may be used alone or in combination of two or more. Charcoal is porous and keeps warm

(Heat insulation effect), excellent deodorizing effect, and can block electromagnetic waves. Bamboo charcoal heat-treated at 800 or more can exhibit particularly excellent electromagnetic wave shielding performance and also has the advantage of being lighter in weight than other charcoals. Therefore, it is one of the charcoals most preferably used in the present invention. One.

The above charcoal is used in powder form. The size of the powder is preferably 0.2 to 0.05 mm (70 to 240 mesh). If the size is 70 mesh or more, the charcoal cannot be sufficiently applied to the cloth or paper, and the raw material is lost, for example, by touching with hand, which is not suitable. Known means such as a cutter and a pulverizer are suitably used as the means for powdering. By making the powder form, the area where the charcoal comes into contact with the outside air when the charcoal is adhered to the cloth or paper surface is increased, so that an excellent heat retaining effect and deodorizing effect can be obtained.

Second, plant fibers have the effect of absorbing carbon dioxide and purifying the air. Specific examples of plant fibers include idasa, palm skin, sugar cane, straw, rice hull, wheat hull, corn skin, bamboo shoot skin, reed grass, mugwort, tree 'bamboo fiber, bamboo shoot skin or pampas grass. Weed fibers. These can be used alone or in combination of two or more. Wear. As a preferred example of the combination, a case where 100 to 40 parts by weight of the fiber of ixa is combined with 30 to 40 parts by weight of the fiber of the coconut skin can be mentioned. Here, since the fiber of the palm skin does not absorb moisture unlike idasa, the water absorbency of the flexible sheet as a whole can be arbitrarily adjusted by combining with the fiber.

The above plant fibers are used in powder form. The size of the powder is suitably 0.2 to 0.05 mm (70 to 240 mesh). When the size is 70 mesh or more, the mixing of the vegetable fiber with other raw material mixtures (such as charcoal) becomes uneven, and the vegetable fiber becomes less compatible with cloth or paper, and is further obtained. It is not suitable because the surface of the flexible sheet becomes uneven and loses flexibility. Known means such as a cutter and a pulverizer are appropriately used as the means for forming a powder.

Among the above-mentioned powdery plant fibers, powdery rush fiber is preferably used because it has appropriate water absorption and is excellent in humidity control. By using a used tatami mat that is old and discarded, the flexible sheet of the present invention can be manufactured at a lower cost and is economically excellent.

It is preferable that the fiber of ixa is previously subjected to mud dyeing. This makes it possible to keep the fiber of the exotherm from rotting. Specifically, it is preferable to add digsa to soil containing lime and perform mud dyeing. After that, dry thoroughly with mud on, and remove the mud attached to igusa. Drying is carried out in the sun or with a dryer.

Preferably, the idasa fibers are further steamed to soften the fibers. By doing so, the fibers of the idasa can be easily blended with the cloth or paper, and the original softness of the cloth or paper is not impaired. Depending on the use of the flexible sheet, it is not necessary to steam. Either the mud dyeing process or the steaming process may be performed first.

The above-mentioned powdery plant fiber may not necessarily be blended as a raw material mixture depending on the use of the produced flexible sheet.

The raw material mixture in the present invention further comprises a powdery ceramic, or Powdered shells can be included. Known ceramics can be used as the ceramic, and also include those fired using diatomaceous earth or white sand as a raw material. As the shell, commonly known shells such as sea shells, oysters, oyster shells, and clam shells can be applied. Any of the above ceramics and shells can be used alone or in combination of two or more. The size of the ceramic and the shell is suitably in the range of 0.1 to 0.05 mm (120 to 240 mesh). By using a powdery ceramic or a powdery shell, the obtained flexible sheet is given appropriate flame retardancy.

Further, the above-mentioned raw material mixture can be blended with an insect repellent / antiseptic component. Preferable examples of such insect repellent and antiseptic components include wood vinegar, bamboo vinegar, persimmon vine, vegetation extract, and mugwort liquid. These have been used as medicinal herbs for a long time, and also have the function of maintaining the freshness of fruits and the like. Any of the above insect repellent and preservative components can be used alone or in combination of two or more.

When the above insect repellent and preservative components are blended, the concentrate may be used as it is, or may be diluted with an appropriate amount of water. Specifically, it is preferable to dilute it 10 to 50 times. Since the above insect repellents are natural, there is no risk of harm to the environment when disposed.

The above insect repellent and antiseptic components are compounded by impregnating or containing at least one of powdered charcoal constituting the raw material mixture or other raw materials such as powdered plant fiber, or a method in which each raw material is mixed. In preparing a raw material mixture by mixing, the method is carried out by adding an insect repellent / preservative component to the mixed system. In the case where each material is previously impregnated with an insect repellent / preservative component by the former method, it is preferable to dry the material after the impregnation operation. Further, if necessary, the insect / preservative component can be impregnated in advance on a cloth or paper to which the raw material mixture is adhered.

Further, powdered carbon can be blended into the raw material mixture. The size of the powder should be 0.2-0.05 mm (70-240 mesh) Is appropriate. Since carbon has high electrical conductivity, excellent electromagnetic wave shielding properties can be obtained as a whole of the flexible sheet.

In addition, a metal powder can be added to the raw material mixture in addition to the above various raw materials. It is appropriate that the size of the powder be 0.2 to 0.05 mm (70 to 240 mesh). Specific examples of the metal include copper, stainless steel, aluminum, and iron. By using a metal powder in combination, it is possible to enhance the electromagnetic wave shielding property.

Furthermore, tourmaline powder may be added to the raw material mixture in addition to the above various raw materials. Tourmaline, also known as tourmaline, is an ionic crystal ore composed of Ca, K, Na, Al, Cr, Fe, Li, Mg, Mn, Si, etc. is there. The flexible sheet prepared by blending this tourmaline with the raw material mixture has excellent deodorizing / deodorizing effects, antibacterial effects, and the like. Suitably, the size of the tourmaline powder is 0.2-0.05 mm (70-240 mesh).

A binder is added to the raw material mixture, if necessary, in addition to the above various raw materials. As the binder, various known adhesives or pastes can be appropriately selected and used. Synthetic adhesives such as acrylic, vinyl acetate, polyolefin, synthetic rubber, and silicone rubber, and two-component adhesives can be used. Examples include natural adhesives such as glue made from starch, alginic acid, chitosan, etc., and inorganic pastes such as water glass. Any of these binders may be used alone or in combination of two or more. Among the above binders, starch paste, vinyl acetate resin emulsion adhesive, polyvinyl alcohol adhesive, and hot melt type adhesive of polypropylene are preferably used.

It is also preferable to use a binder that does not generate toxic gas by incineration or a binder that can be decomposed in soil, because the flexible sheet as a whole does not pollute the environment even when discarded. Examples of such a binder include inorganic glue.

Furthermore, those that can be blended into the raw material mixture include And bamboo scraps. The types of trees include kenaf, cedar, oak, kuromoji and other miscellaneous trees, and the types of bamboo include, but are not limited to, kumazasa, masatake, moso bamboo and the like. Further, as described above, these raw materials can be impregnated with insect repellent and antiseptic components in advance. The method of impregnation is to immerse driftwood, wood chips, and bamboo chips in insect repellent and antiseptic solution.Put driftwood, wood chips, and bamboo chips in a vacuum compressor, inject the insect repellent and antiseptic solution, and then apply vacuum. Therefore, a method of sucking insect repellent and preservative liquid can be used as appropriate. Driftwood, wood chips, and bamboo chips are also used in powder form. The size at that time is preferably 0.2 to 0.05 mm (70 to 240 mesh).

In addition, the raw material mixture may contain a so-called herb used as a herbal flavor. Herbs are used to combat insect and preservative odors. One type of herb can be used alone, or two or more types can be combined.

As described above, the cloth or paper to which the raw material mixture containing the various raw materials is adhered includes non-woven fabrics of various types such as Japanese paper, cotton cloth, linen cloth, polypropylene, etc., cloth made of acetate resin, commercially available cloth, and Firzin. A commonly used cloth or paper such as paper can be applied. Depending on the use of the manufactured flexible sheet, a coarse sheet such as Japanese paper is preferably used. The thickness of the cloth or paper is preferably thin so that the raw material mixture can be easily blended. Further, non-combustible paper, cloth, non-woven fabric and the like can also be used.

Next, the manufacturing process of the flexible sheet will be described.

The flexible sheet is obtained by preparing a raw material mixture from powdered charcoal and other raw materials such as powdered vegetable fiber and attaching the mixture to a cloth or paper surface.

For the preparation of the raw material mixture, for example, a known method such as a method in which other raw materials such as powdered charcoal and powdered plant fiber, a binder, and the like are put into a stirrer and stirred may be applied. When a glue film described later is used as the binder, it is not necessary to add the binder at the stage of preparing the raw material mixture.

The mixing ratio of each raw material in the raw material mixture should be set appropriately according to the application Can be. Specifically, when the amount of the powdered charcoal is 100 parts by weight, the amount of the powdery plant fiber is suitably from 0 to 60 parts by weight, and preferably from 5 to 15 parts by weight. When the binder is used in a large amount, the air permeability of the flexible sheet is impaired, and the effect such as the deodorizing effect cannot be sufficiently exhibited. Therefore, the binder is preferably used in an amount of about 10 to 60 parts by weight. Most preferably, it is 25 to 35 parts by weight.

The mixing ratio of the powdered carbon is, assuming that the powdered carbon is 100 parts by weight, preferably 0 to 120 parts by weight, and more preferably 20 to 100 parts by weight.

Further, the powdery ceramic or shell is suitably from 0 to 20 parts by weight, preferably from 3 to 15 parts by weight, based on 100 parts by weight of the powdered charcoal. .

The amount of the insect repellent / preservative component is suitably 0 to 15 parts by weight, preferably 5 to 15 parts by weight, based on 100 parts by weight of powdered charcoal. In the case where the insect repellent and preservative components are diluted, impregnated with other raw materials, and dried, the amount includes diluted water and the like before drying.

The metal powder is suitably used in an amount of from 0 to 200 parts by weight, preferably from 10 to 180 parts by weight, based on 100 parts by weight of the powdered charcoal.

The amount of tourmaline powder is suitably 0 to 15 parts by weight, preferably 3 to 10 parts by weight, based on 100 parts by weight of powdered charcoal.

Further, with respect to driftwood, wood chips, and bamboo chips, 0 to 5 parts by weight, and preferably 3 to 5 parts by weight, of powdered charcoal is 100 parts by weight. The herb is preferably used in an amount of 0 to 10 parts by weight.

The amount of the raw material mixture adhering to the cloth or paper is not particularly limited and can be appropriately set, but is preferably 1 to 10 mg / cm ² , and most preferably 2 to 10 mg / cm 2. ~ 4 mg. If it is higher than this value, the air permeability of the cloth or paper may be impaired or lost,

There is a mouth, and the cloth or paper loses its flexibility, and the adhering raw material mixture tends to crack, resulting in a lack of raw material.

The method of attaching the raw material mixture is as follows: Or a method in which the raw material mixture is supplied to a sizing machine and spread on cloth or paper by the sizing machine, or a method in which the raw material mixture is spread on cloth or paper by Curtain Flowco. Selected. Among them, the curtain flow coating method is preferably used because the raw material mixture can be efficiently adhered to a large-area cloth or paper. The so-called lip, which is the raw material outlet of the Curtain Flowco, may be a slit-like shape that is usually used, but a plurality of holes 17 as shown in Fig. 4 are provided as other shapes. The shape can also be changed. Since the slit-shaped lip usually has a gap of only about 0.5 mm, the flow of the raw material mixture may be hindered in some cases.On the other hand, if the shape is as shown in Fig. 4, Since the diameter of the hole 17 can be made larger than that in the case of the slit, the raw material mixture can be adhered smoothly and uniformly.

As another form of the Curtain Flowco, as shown in Fig. 5, the raw material mixture 6 is supplied from the hopper 5 to the Curtain Flowco 18 and the power is reduced without flowing down from the rib. The raw material mixture 6 can overflow from the upper part of the flow coater 18 and adhere to the cloth 19 or the like. In this way, the overflowing raw material mixture 6 is separated and adheres to the cloth 19, so that it is easy to control the amount of the cloth 19 attached per unit area to a very small amount. The raw material mixture can be attached to only one side of the cloth or paper, or can be attached to both sides. Further, another cloth or paper can be further stacked on the cloth or paper to which the raw material mixture is adhered.

The cloth or paper to which the raw material mixture has been adhered by the above method is further pressed and compressed as necessary, so that the raw material mixture can be evenly spread over the entire surface of the cloth or paper so that it fits into the cloth or paper. I do. As a specific means, a method of pressing and compressing a cloth or paper to which the raw material mixture is adhered by a roller, a press, or the like can be given. The pressure at that time is suitably 1 to 5 kg / cm ² , and preferably 2 to 3 kg Z cm ² . When a method of uniformly spraying the raw material mixture onto the surface of the cloth or paper is employed, the pressing may or may not be further performed. In addition, it is preferable to heat together with pressing and compression. The temperature is set according to the type of the binder mainly used. For example, when the binder is starch-based paste, 100 to 140 t :, vinyl acetate resin emulsion-based adhesive In the case of (1), the temperature is 140 to 180 ° C, and in the case of a polypropylene hot-melt type adhesive, the temperature is 130 to 180 ° C. In the case of a solid binder such as a hot-melt adhesive, a heating step is indispensable because it needs to be melted.

In order to simultaneously perform pressing, compression, and heating, a heating roller, a high-frequency press, or the like is appropriately used.

A glue film can be used as a binder. The glue film does not need to be incorporated into the raw material mixture. That is, a glue film is layered on a cloth or paper, a raw material mixture is further spread thereon, a glue film is further layered as necessary, and the glue film is melted by pressing and compressing while heating by the above-described means. Then, the raw materials can be combined to obtain a target flexible sheet.

In addition, the glue film that is cut into small pieces into a string can be mixed into the raw material mixture. This method is preferably used because the paste and the raw material mixture are easily mixed uniformly. As a specific example of the cord-like material, a cord-like glue film having a width of l to 3 mm and a length of 5 to 300 mm can be given.

Finally, it is preferable that the flexible sheet is appropriately dried in order to remove the solvent for the insect repellent / preservative component and the binder, or the remaining moisture. The appropriate drying temperature is 20 to 150 ° C and the appropriate time is 1 to 120 minutes.

Hereinafter, the manufacturing process of the flexible sheet of the present invention will be described with reference to the drawings, but the present invention is not limited thereto.

Also, a wood grain pattern or the like can be appropriately printed on a wooden board (sheet) or a plastic board (sheet) for the purpose of decoration or the like. Further, a metal mesh is used to improve the electromagnetic wave shielding property of the entire flexible sheet, and specific examples thereof include meshes of stainless steel, aluminum and the like. In addition, the mesh roughness of the metal mesh and the force mesh is not particularly limited. It is preferably about 0.5 mm. The above-mentioned wooden sheet, decorative board, plastic sheet, iron sheet, aluminum sheet, metal mesh, or carbon mesh (hereinafter referred to as “wood board”) is a flexible sheet obtained by attaching a raw material mixture to cloth or paper. When laminating the flexible sheets, the flexible sheet and the above-mentioned wooden board or the like may be attached by appropriately using a binder or the like. At this time, a wooden board or the like can be attached to one side of the flexible sheet obtained by attaching the raw material mixture to cloth or paper, or a wooden board or the like can be attached to both sides. Conversely, the above-described flexible sheets obtained by adhering the raw material mixture to cloth or paper may be attached to both sides of a wooden board or the like. The means for sticking is not particularly limited. For example, the paste is spread by a spreader or a sizing machine on the above-mentioned flexible sheet obtained by adhering the raw material mixture to cloth or paper. Means such as bonding with a press machine are appropriately used. When a flexible sheet is manufactured by laminating a wooden board or the like, a part or the whole of the raw material mixture is attached to a wooden board or the like in advance, and then the raw material mixture is laminated. The present invention also includes a case where an object is attached to cloth or paper.
