Description

  The present invention relates to Japanese paper considering health and hygiene by dispersing barley stone powder and propolis bulk powder in Japanese paper used for wallpaper, shoji, interior goods, and the like.

  In recent years, buildings such as ordinary houses and office buildings have been improved in energy saving effect and have improved airtightness and heat insulation. As a result, dampness remains in the room due to incomplete ventilation, and dew formation occurs, so that the building is easily corroded. In addition, because of the environment where ticks and molds are likely to be generated, these dead bodies become house dust and drift inside the room, which can adversely affect human health. Therefore, antiseptics, fungicides and the like are used for building materials.

  However, by using preservatives and fungicides for building materials, harmful volatile organic compounds such as formaldehyde, toluene, xylene, and acetaldehyde (hereinafter referred to as hazardous chemical substances) contained in the building Sick house syndrome, which is diffused into the atmosphere and manifests various symptoms such as mental disorders such as headaches, mental disorders such as depression, respiratory disorders such as breathing difficulties, skin disorders such as rash, etc. is a major social problem .

  As countermeasures against sick house syndrome, it is effective to reduce the concentration of harmful chemical substances in the room, and recently, building materials with a low content of harmful chemical substances have been used in buildings.

  However, at present, harmful chemical substances are released into the atmosphere not only from building materials but also from a wide variety of chemical products such as indoor furniture, curtains, fragrances and insect repellents.

In view of this, a method has been adopted in which harmful chemical substances in the room are adsorbed using carbide, which is a porous substance, to prevent re-emission into the atmosphere. For example, Patent Document 1 proposes a technique related to a sheet in which activated carbon is fixed inside through heat-bonding powder and heat-bonding fibers, and Patent Document 2 proposes a technique related to wallpaper in which carbide is laminated on the back surface of interior paper. Yes.

  However, even if carbide is used as an adsorbing material for harmful chemical substances, the carbide itself does not possess the property of decomposition of the adsorbing substance, so the pores of the carbide immediately become saturated and clogged. It is difficult to keep the effect for a long time.

  An object of the present invention is to take measures against sick house syndrome, and in view of the above-mentioned problems, a material that can be expected to have a long-lasting effect while selecting a natural paper mixed material is selected, and these are made in Japanese paper. It is to provide Japanese paper considering health and hygiene aspects by improving the original effect of Japanese paper by dispersing it not only on the surface but also inside.

  Be sure to use both natural porcelain ore and natural propolis block as materials mixed in Japanese paper (hereinafter referred to as mixed paper material) and disperse it on the surface and inside of Japanese paper. It is characterized by adding air purification, deodorization, antibacterial, sterilization, and antiseptic effects while improving the adsorption and humidity control effects inherent in Japanese paper.

  Furthermore, the barley stone and the propolis raw mass which are mixed paper materials are powders, and the particle size of the propolis raw bulk powder is equal to or larger than the particle size of the barley stone powder.

  In addition, in order to disperse the mixed paper material on the surface and the inside of the Japanese paper, after adding the Japanese paper raw material and water to the beater in the beating process, the solution was adjusted by adding the paper paste and the mixed paper material and stirring. (Hereinafter referred to as a mixed paper solution). In addition, the ratio of the mixed paper material in the mixed paper solution is preferably 0.1 to 10% by weight of the barleystone powder and 0.1 to 5% by weight of the propolis raw powder with respect to the raw material of the Japanese paper.

  According to the present invention, barley stone powder and propolis powder can be easily dispersed on the surface and inside of Japanese paper, and the harmful chemical substances diffused indoors due to their properties are adsorbed and decomposed to prevent re-emission. Cleansing effect, deodorization effect that absorbs and decomposes odor, adsorption effect that absorbs dust, humidity control effect that absorbs and releases moisture and keeps humidity constant, antibacterial effect that absorbs and decomposes bacteria, Escherichia coli, etc., bactericidal effect Can expect antiseptic effect. In addition, it is hoped that these effects will be prolonged.

  In addition, the Japanese paper of the present invention itself is made from natural materials and does not contain any harmful chemical substances. Therefore, it is suitable for use in indoor wallpaper, shoji, interior goods, etc. Even if burned, it will not pollute the environment.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  1 to 2 relate to an embodiment of the present invention, FIG. 1 is a cross-sectional view thereof, and FIG. 2 is a flowchart of a manufacturing process.

  Washi 16 absorbs moisture when the humidity is high, and releases moisture stored when the humidity is low, and has an adsorption effect that absorbs dust. It itself is made from natural materials such as Kozo, Mitsugi, and Kenaf. Therefore, using Japanese paper for wallpaper, shoji, interior goods, etc. is effective in preventing sick house syndrome.

Moreover, the barleystone 17 which is a natural ore has a property that it has a very large surface area because of its porosity, and continues to have porosity even if it is crushed to a small extent. The total surface area of 1 g of barley stone is as high as several hundred m ^2, which is about 20,000 times that of activated carbon having the same structure and the same mass, so the adsorption capacity is very strong. Also, the main difference from activated carbon is not only adsorption of substances, but also possesses the ability to decompose and remove harmful chemical substances, chemical compounds, bacteria, cadmium, cyanide, E. coli, mercury, chlorine, ammonia, etc. It has become clear. For this reason, since the pores of the barley stone are unlikely to become saturated, the decrease in the adsorption capacity of the barley stone 17 is gradual. Due to the above properties, the barley stone 17 adsorbs and decomposes harmful chemical substances that are diffused indoors to prevent re-emission, air purification effects that absorb and decompose indoor odors, bacteria, Escherichia coli, etc. Antibacterial effect that adsorbs and decomposes moisture, and humidity control effect that keeps humidity constant by absorbing and releasing moisture can be expected. In addition, prolongation of these effects can be expected.

  On the other hand, the propolis block 18 is made by chewing resin collected from various trees in nature with saliva, which is its endocrine solution, and containing flavonoids as the main component. It is a natural material possessing bactericidal, antibacterial and antiseptic effects such as bacteria.

  By making both the above-mentioned barley stone 17 and the propolis bulk block 18 into a mixed paper material for the Japanese paper 16, each of the three effects can be fully exerted, and the synergistic effects can be adsorbed on the Japanese paper, humidity control, and air. Purifying, antibacterial, bactericidal and antiseptic effects can be retained. For example, by dispersing barley-stone in Japanese paper, the adsorption and humidity control effects inherent in Japanese paper are improved, and the antibacterial effect can be improved by using both barley-stone and propolis bulk as a mixed paper material. .

  The traditional Japanese paper manufacturing process consists of a ripening process that makes the Japanese paper raw material boiled easily, a beating process in which the raw material cooked in a beater and water are beaten, and a paper machine is used for papermaking. The process is performed in the order of a compression process in which the thickness is adjusted by a pump, and a drying process in which the moisture is adjusted by pressing and dried.

  As shown in FIG. 2, the Japanese paper of the present invention produces a mixed paper solution prepared by adding a paper paste and a mixed paper material and stirring the beater after adding the Japanese paper raw material and water to the beater in the beating process. To the conventional Japanese paper manufacturing process (hereinafter referred to as a mixed paper solution generation process). By collecting the mixed paper solution generated in this process in a tank and applying it to a paper machine, it becomes very easy to make a Japanese paper in which the mixed paper material is dispersed to the surface and inside as shown in FIG.

  In addition, the barley stone 17 and the propolis original lump 18 which are mixed paper materials in a mixed paper solution production | generation process must be a powder. By making the mixed paper material into powder, it can be easily dispersed in the mixed paper solution, and the paper paste can be used as a binder, so that precipitation in the mixed paper solution can be prevented. In addition, it should be noted at this time that the particle size of the propolis bulk powder is to prevent clogging due to the propolis bulk powder entering the pores of the porous barley stone powder. Must be greater than the particle size of the powder. In addition, the ratio of the mixed paper material in the mixed paper solution is preferably 0.1 to 10% by weight of the barley stone powder and 0.1 to 5% by weight of the propolis raw powder with respect to the raw material of the Japanese paper. . If the ratio of the mixed paper material is increased further, the texture of the Japanese paper will be impaired, and even papermaking will be difficult.
