For this reason, moisture and odor tend to be trapped in the room, making it uncomfortable to live in and unfavorable for health. This tendency is particularly strong in a concrete building. In order to solve the above problems, bamboo charcoal having the property of absorbing moisture and odor is powdered and solidified with cement to form a bamboo charcoal board (Japanese Unexamined Patent Publication No.

Due to its heavy weight, transportation costs are increased, and it is difficult to handle at a construction site, and a great deal of labor is required for construction. When the humidity is high, a certain amount of moisture is absorbed, but when the humidity is low, that is, at the time of drying, the absorbed moisture cannot be released. The ability to absorb odors emitted from building materials and human bodies used in rooms is small. The generation of negative ions inherent in charcoal is prevented. In addition, the above and problems are that when the bamboo charcoal powder is solidified with cement and formed into a board, the paste of the cement closes most of the fine holes of the bamboo charcoal, losing the original properties of bamboo charcoal, Probably caused.

は限定されない。As the charcoal, bamboo charcoal, charcoal, coconut shell charcoal or activated charcoal is used. Bamboo charcoal is most preferable from the viewpoints of moisture absorption / desorption, odor absorption and generation of negative ions. In addition, bamboo charcoal is less likely to be mixed with other materials than charcoal and the like, and has a constant quality. As the organic binder, a thermosetting resin is preferable from the viewpoint of binding properties to bamboo charcoal and physical properties such as lightness and hardness of the formed board. As thermosetting resin,
Urea resin, melamine resin, melamine-urea co-condensation resin, phenol resin, resorcin resin, epoxy resin,

If the amount of the organic binder is less than 5 parts by weight, the moldability may be poor and the board may not be formed. If the amount exceeds 60 parts by weight, the properties of the bamboo charcoal are impaired, and the moisture absorption / desorption properties and odor absorption properties are reduced. Ions may not be generated sufficiently. As the release agent, for example, a wax emulsion or a silicone emulsion is used,
It is not limited to these. The mixing ratio of the release agent is not particularly limited, but it is usually sufficient to use 0.1 to 1.0 part by weight with respect to 100 parts by weight of charcoal.

The mixing ratio of the filler is not particularly limited, but it is preferable to use 30 to 70 parts by weight based on 100 parts by weight of charcoal. If the amount of the filler is less than 30 parts by weight, the proportion of expensive charcoal increases, which is disadvantageous in terms of production cost. If the amount of the filler exceeds 70 parts by weight, the properties of bamboo charcoal are easily impaired, and moisture absorption and desorption properties and odor absorption properties And the generation of negative ions may decrease. As a sheet to be stretched on one or both sides of the charcoal board to provide hygroscopicity or shape retention, for example, Japanese paper, Western paper, synthetic paper, cloth, nonwoven fabric, etc. are used, but are not limited thereto. is not.

Therefore, since charcoal is bound with a light weight organic binder such as a thermosetting resin,
The charcoal board can be made lighter than a charcoal board hardened with cement. Therefore, the transportation cost can be reduced, and it is easy to handle at the building site and easy to construct.

われる。Further, an organic binder such as a thermosetting resin is used to bond the charcoal. The thermosetting resin is a liquid having a higher viscosity than a cement paste or the like due to heating at the time of forming the charcoal board. Be a body. Therefore, even when mixed and stirred with charcoal, it is difficult to penetrate into the fine pores of the charcoal, and most of the fine pores are not blocked as in the case of cement paste. Therefore, it is possible to prevent the vast surface area of the micropores from being greatly reduced, and the properties inherent to charcoal are substantially maintained, so that even when molded into a board shape, excellent moisture absorption / desorption properties and odor absorption properties are obtained. It can be fully demonstrated. Further, generation of negative ions is sufficiently performed.

えることができる。When a mold release agent is contained, mold release from the mold (or mold) during molding can be improved, and workability can be improved. Those containing a filler such as plaster, perlite or vermiculite can use less coal, and the filler is less expensive than charcoal, so that the product cost can be reduced.

However, even if the shape is somewhat easily deformed, the shape can be prevented from being deformed. Furthermore, it is possible to prevent the hands from being soiled during construction.

いので上記作業も含めて全ての作業が行いやすかった。In order to compare the wall material according to the present embodiment with another wall material, a wall material in which 100 parts by weight of a bamboo charcoal granule having a particle size of 3.0 to 3.5 mm is combined with 53 parts by weight of cement. Was made as a comparative example. Two 8-tatami Japanese-style rooms were prepared, of which the wall material 1 according to the present embodiment was constructed in one room, and the wall material of the comparative example was constructed in other rooms. At the time of this construction, the wall material according to the present embodiment was easier to cut with a saw and nails easier than the wall material of the comparative example. In addition, since it was light, all the operations including the above operations were easy to perform.

発散されていたと考えられる。Two persons each lived in the above two rooms for one year, and were subjected to a sensory test. As a result, in the room in which the wall material of the comparative example was constructed, dew was condensed on the walls and the like in winter, and steamy heat and the like were felt in summer, and unpleasant odors were easily muffled. On the other hand, in the room where the wall material 1 according to the present embodiment is constructed, no dew condensation is observed on the walls and the like in the winter, no humid heat is felt in the summer, and an unpleasant smell is also contained. No moisture absorption and deodorization and excellent odor absorption were found. Further, in the room where the wall material 1 according to the present embodiment was constructed, the user felt a feeling of mental liberation and sedation compared to the room in which the wall material of the comparative example was constructed. It is considered that the negative ions were sufficiently diffused from the wall material 1.

取扱いやすく施工も容易である。The present invention has the above configuration and has the following effects. (A) The charcoal board according to the invention includes charcoal such as bamboo charcoal and an organic binder such as a thermosetting resin for bonding the charcoal.
Therefore, since the charcoal is bonded with an organic binder having a light weight per unit volume such as a thermosetting resin, the charcoal board can be made lighter than a charcoal board hardened with cement. Therefore, the transportation cost can be reduced, and it is easy to handle at the building site and easy to construct.

われる。(B) An organic binder such as a thermosetting resin is used for binding the charcoal, but the thermosetting resin has a higher viscosity than a cement paste or the like due to heating at the time of forming the charcoal board. It becomes a liquid. Therefore, even when mixed and stirred with charcoal, it is difficult to penetrate into the fine pores of the charcoal, and most of the fine pores are not blocked as in the case of cement paste. Therefore, it is possible to prevent the vast surface area of the micropores from being greatly reduced, and to maintain the original properties of charcoal almost unchanged, so that even when molded into a board shape, excellent moisture absorption / desorption properties and odor absorption properties are obtained. It can be fully demonstrated. Further, generation of negative ions is sufficiently performed.

Even if the compounding ratio of the binder is small and the shape is somewhat easily deformed, the shape can be prevented from being deformed. Furthermore, it is possible to prevent the hands from being soiled during construction.
