2. Description of the Related Art In recent years, urban centers have been extremely concentrated, and in urban areas, facilities such as stores and offices or residential buildings are not made to have a heavy frame structure for effective use of land. In addition to the increasing number of high-rise buildings, residential buildings using prefabricated construction methods and pre-cut construction methods, which are excellent in earthquake resistance and fire resistance and inexpensive in addition to various designs, are also actively employed in general detached houses. It is getting.
In addition, due to the use of high-dimensional building materials such as aluminum sash and new building materials for these buildings, the hermeticity of these building spaces is significantly increased.

[0003] For this reason, in a store complex where special ventilation and cleaning facilities are not fully equipped, the odor generated from a specific store or a sales corner is accumulated in the store complex and the entire building space is uncomfortable. In addition, in the office building, in addition to the recent changes in the eating habits of employees, so-called home meals, various kinds of lunches and prepared dishes are brought in and eaten,
Odors generated from these substances are diffused and retained, especially in residential buildings, where residents always live.Therefore, odors associated with foods and meals, as well as denaturation of perspiration, skin, body fluids, etc., decay odor, cosmetics, etc. Residential buildings are warm and inadequately ventilated throughout the year due to the increase in airtightness, as well as odors, bath additives and smoking odors. In order to have
Living odors are combined with the propagation odor associated with the propagation of these bacteria and fungi, and these odors not only fill up the living buildings, but also penetrate and penetrate into building materials, interior materials, furniture furniture, etc. In particular, it is extremely uncomfortable for foreigners.

In addition, bacteria and fungi not only rapidly propagate in a very short period of time, but also cause deterioration of the building frame and discoloration of interior materials and furniture furniture due to secretions secreted by the propagation. The inside of the building space is extremely unsanitary, such as fouling, and the dead bodies of these bacteria and fungi become allergens and induce atopic diseases, and the dead bodies of these fungi feed together with mite and other unpleasant pests. Is in a state of being. At present, chemical fungicides are sprayed to prevent the propagation of these bacteria and fungi, and chemical insecticide gas for insect control is diffused and filled, on the other hand, volatile organic compounds generated from interior materials etc. (VO
It is stronger and more dangerous than sick house syndrome caused by C) or volatile organic solvents.

The present inventors have conducted intensive studies in view of such circumstances, and as a result, the odor gas containing odor molecules, the volatile solvent gas or the volatile organic compound has a large adsorption capacity of at least 50 m ² / g in a substantial specific surface area. Is positively adsorbed on the porous material, and the base material has high base substitution property, that is, its substantial base substitution capacity (meg / 1
00g) retains a base substitution property of at least 120 to 150 mg or more, not only can the adsorbed odor molecules and volatile organic compound molecules be decomposed and eliminated to achieve deodorization, but also the adsorption amount becomes saturated and the adsorbability and Determined that the decomposability was maintained for a long period of time, and furthermore, by using an aluminosilicate mineral as the porous substance, it was possible to exhibit moisture absorption in humid conditions and moisture release during drying, so-called humidity control. did.

For this reason, the inventors have disclosed in Japanese Patent Application Laid-Open No. 11-19922 and Japanese Patent Application Laid-Open No.
302012, JP-A-2000-26488 or JP-A-2000-143234 With the cooperation of the inventor, an attempt was made to produce an artificial zeolite, which is an aluminosilicate mineral, using casting waste sand as a raw material. 0.5
6, particle diameter 5 to 10 μm, pore diameter 5 to 10 A, specific surface area 70 to 100 m ² / g, and base substitution capacity (me
g / 100 g) 200 to 400 mg, an elution pH value of 5 to 11, production of an artificial zeolite having a moisture absorption capacity of 20 to 50% was confirmed, and the present invention was reached.

[0007]

That is, the present invention can be used as a ceiling material or a wall material for forming a building space, or as a partition wall, so that an odor gas, a volatile solvent gas or a volatile organic compound can be actively used. It is an object of the present invention to provide a deodorizing and humidity controlling plate material capable of realizing a safe, hygienic and comfortable building space by absorbing and decomposing and eliminating and controlling humidity.

[0008]

The technical means used by the present invention to solve the above-mentioned problems include fire resistance, water resistance, light weight, toughness required for ceiling materials and wall materials. In addition to processability, it is possible to absorb a sufficient and large amount of odor gas, volatile solvent gas or volatile organic compound, and to promote the absorption and release of humidity. In addition to the use of a material, an odor gas, a volatile solvent gas, or a volatile organic compound is positively and efficiently adsorbed on one side or both sides of the base material to be decomposed and eliminated, and the average particle size is 30 μm or less. It has a large adsorption surface area ratio and a large adsorption capacity with a specific surface area of at least 70 m ² / g. Further, it promotes the decomposition of adsorbed odor gas molecules, volatile solvent gas molecules, volatile organic compound molecules, etc. to be eliminated. Was The base substitution capacity (meg / 10
0 g) of at least 200 mg or more of artificial zeolite powder in a volume of 55 to 90%, and a cement or cement made of dolomite plaster in order to enhance the fixability and coatability of the deodorant humidity control layer formed by coating. ~ 25%
An adhesive made of a cellulose derivative or sodium alginate is used to impart toughness and shape retention to the capacity and the deodorizing humidity control layer formed by coating, and to achieve firm coating with the substrate. A deodorant humidity control layer having a composition of about 20% by volume is formed by coating.

Further, in the present invention, the base material is made of a woven or knitted fabric obtained by weaving or knitting a metal fiber, a synthetic fiber or a natural fiber, and a deodorizing humidity control layer is applied to both sides of the base material. A configuration in which chopped strands formed of inorganic fibers, and having a diameter of 0.03 mm or less and appropriately cut into lengths, are blended in an amount of 3 to 10% by volume, In order to increase the adsorbability and hygroscopicity of odor gas etc. by forming ventilation holes for lightening of the overall weight and air permeability and moisture, inorganic zeolite powder consisting of perlite, shirasu balloon, fly ash balloon in artificial zeolite powder A foam material is present in a composition of 10 to 30% by volume.

[0010]

Since the present invention has the above-described structure, the present invention has the following functions. That is, the base material is formed of an inorganic porous material having air permeability, and on one or both sides thereof, an artificial zeolite powder having a required performance is provided with a fixing material made of cement or dolomite plaster in a volume of 55 to 90%. 7 to 25% by volume, and 3 to 20 adhesives composed of a cellulose derivative or sodium alginate.
% By volume, the odor gas, the volatile solvent gas, and the volatile organic compounds generated and diffused in the building space have a relatively smaller pore size than the deodorant humidity control layer. It is easy to penetrate into a large porous base material. With this penetration, odor gas, volatile solvent gas or volatile organic compound is converted into artificial zeolite powder having a large adsorption surface area ratio and a large adsorption capacity, so-called large specific surface area. While being positively adsorbed, it is decomposed and eliminated due to the high chlorine-substituting property that is retained, so that the adsorbing property is maintained for a long time, and excess moisture is also actively absorbed and retained.

[0011] Since the deodorizing and humidity controlling layer contains a cement or a dolomite plaster in a volume ratio of 7 to 25% by volume, the deodorizing and humidity controlling layer to be applied is firmly formed. At the same time, air permeability and moisture permeability are maintained, and coating with the base material can be performed well. In addition, since the deodorant humidity control layer contains an adhesive composed of a cellulose derivative or sodium alginate at a volume ratio of 3 to 20%, the deodorant humidity control layer formed by coating is toughened. Even when formed thin, cracks are prevented from being generated, and strong coating is performed irrespective of the material of the base material.

Further, chopped strands composed of inorganic fibers and having a diameter of 0.03 mm or less and appropriately cut into lengths are blended in the deodorizing humidity control layer of the present invention in a proportion of 3 to 10% by volume. Since the chopped strands are sufficiently fixed and adhered to the fixing material and the adhesive, cracks during drying can be prevented even in the deodorant humidity control layer formed particularly in a thin wall, and the deodorant humidity control layer is formed. By blending the inorganic foaming material in the artificial zeolite powder to be formed at a volume ratio of 10 to 30%, a large number of relatively large pores are formed in the deodorizing humidity control layer formed by coating, thereby reducing the weight. Adsorption and absorption of odorous gases and humidity are significantly improved. Also, in a configuration in which a woven or knitted fabric obtained by weaving or knitting a metal fiber, a synthetic fiber, or a natural fiber on the base material of the present invention and a deodorizing humidity control layer is applied and sandwiched on both sides of the base material as a whole, The base material is reinforced and the shape retention is enhanced, and the composition ratio of the artificial zeolite powder is remarkably increased. Due to its large surface area ratio and specific surface area, adsorption and decomposition and elimination of odor gas, volatile solvent gas or volatile organic compound are eliminated. Properties or moisture absorption / release properties are significantly enhanced.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a sectional explanatory view of the present invention, and FIG. 2 is an enlarged explanatory view of an artificial zeolite powder. It is safe and hygienic by absorbing deodorizing solvent gas or volatile organic compounds, etc., and maintaining deodorizing and adsorbing ability by decomposing and elimination, and absorbing moisture in humid conditions and releasing moisture in drying conditions. In order to realize a comfortable building space, the present invention is usually used as a plate material formed into a flat plate because the present invention needs to be stretched as a ceiling material, a wall material, or a partition wall material.
For this reason, the substrate 1 is preferably air-permeable and preferably has a relatively large air hole diameter 1A and a large specific surface area.
Disperse and mix coal powder or wood powder etc. into concrete open-cell board, clay fired board, diatomaceous earth board, ceramic open-cell board or shale or clay of about 0 to 500 μm, and fire to burn off the coal powder or wood powder. An inorganic porous plate material is used.

Odor gas, volatile solvent gas or volatile organic compound generated and diffused in the building space is positively adsorbed on one or both side surfaces of the selected substrate 1 and decomposed and eliminated to deodorize and adsorb. The deodorizing and humidity-controlling layer 2 is formed with a required thickness so as to maintain the performance and to exhibit moisture absorption during high humidity and moisture release during drying, so-called humidity control. The adsorption, decomposition and elimination of the odor gas in the deodorizing humidity control layer 2 and the humidifying and desorbing action of the humidity depend exclusively on the artificial zeolite powder 2A. The adsorptivity depends on the contact surface area ratio and the adsorption capacity with the odorous gas and the like, and the contact area ratio and the adsorption capacity greatly influence moisture absorption and desorption.

Since the present invention is used as a sheet material for practical use, a means for forming the sheet into a flat plate is required. However, in a general firing means, the base substitution property is thermally destroyed and the decomposing / erasing action is also reduced. For this reason, it is inevitable to employ a forming means using the fixing material 2B or the adhesive 2C, that is, a so-called dry solidifying means. However, in the dry solidifying means, the artificial zeolite powder 2A is covered with the fixing material 2B or the adhesive 2C. Since there is a risk that adsorption of odor gas and the like and absorption of humidity may be hindered, even if the fixing material 2B or the adhesive 2C that retains the provisional air permeability or moisture permeability is selected and used, the encapsulation of up to about 30 to 40% is blocked. It is important to select an artificial zeolite powder 2A that can sufficiently exhibit adsorptivity and hygroscopicity. Due to this reason, the artificial zeolite powder 2A for forming the deodorizing humidity control layer 2 has an average particle size of 30 μm or less, and a large number of fine particles so that a large contact surface area is formed as shown in FIG. Since those having a large adsorption capacity having the pores 20A are preferable, the specific surface area is at least 70 m ² / g or more. meg / 100g) is 200
mg or more will be selected.

The deodorant humidity control layer 2 formed on one or both sides of the base material 1 comprises 55 to 90% by volume of the artificial zeolite powder 2A thus selected and the artificial zeolite. In order to fix the powder 2A as a coating layer of a required thickness, to impart shape retention, and to apply the powder to the substrate 1, the bonding material 2B made of cement or dolomite plaster has a 7 to 25% capacity. To give sufficient toughness to the deodorizing and humidity controlling layer 2 and to obtain various base materials 1
In order to achieve strong adhesion, the adhesive 2C made of a cellulose derivative or sodium alginate is formed with a composition of 3 to 20% by volume. In such a case, when cement or dolomite plaster is used as the fixing material, a large number of fine ventilation voids 20B are formed due to the fixing, and the fixing property by the pozzolanic action with the artificial zeolite powder 2A is increased.
The reason why the cellulose derivative or sodium alginate is selected as the adhesive 2C is that the artificial zeolite powder 2A is used.
This is because even when it is wrapped in the adhesive 2C, relatively air permeability and moisture permeability are exhibited, and adsorption and moisture absorption / desorption properties are hardly inhibited. , Methylcellulose, carboxymethylcellulose or acetylcellulose. Practical performance is maintained even when polyvinyl alcohol is used in place of sodium alginate.

As means for applying the deodorizing and humidity controlling layer 2 on the substrate 1, a zeolite powder 2A for forming the deodorizing and humidity controlling layer 2, a fixing material 2B and an adhesive 2C are blended in an appropriate ratio. Water is added at a volume ratio of about 30 to 55% with respect to the total amount, kneaded well to form a viscous coating material, and then applied to a required thickness by an appropriate coating device or manually, and dried. By doing so, the deodorant humidity control plate material 3 of the present invention is created. The deodorant humidity control plate material 3 is used as a ceiling material, a wall material, or a partition wall material.
It is about 5mm thick, and it is almost 1 as wall material or partition wall material.
Since a thickness of about 5 to 30 mm is usually used, the thickness of the substantially deodorizing and humidity controlling layer 2 is approximately 1.8 in the case of a ceiling material.
In the case of a wall material having a thickness of about 3 to 4.2 mm, it is desirable that the wall material is applied and formed to have a thickness of about 3 to 6 mm. In addition, since the artificial zeolite powder 2A is an alkaline silicate mineral, the cement of the fixing material 2B is blended, and the kneading with water may cause a strong pozzolanic effect, which may cause excessive fixation. At most 7-12%
It is desirable to keep the capacity to about the same.

Further, when the deodorizing humidity control layer 2 is formed thin, there is a concern that cracks may be generated due to drying and solidification, or when it is used as a wall material to which an external impact is likely to be applied, cracks due to the application of the external impact may occur. And the danger of cracks. Therefore, as a countermeasure against such a problem, as shown in FIG.
It is proposed that the chopped strands 2D having a diameter of 0.03 mm or less and cut into appropriate lengths be mixed at a volume ratio of 3 to 10%. The reason for the limitation is that a sufficient flexibility is required at the time of coating the fine artificial zeolite powder 2A, and the length of the chopped strand 2D depends on the viscosity of the coating raw material and the coating formation. The thickness is appropriately determined depending on the thickness and the like, but a length roughly corresponding to the thickness to be formed by coating is at most about three times the length. Of course, specific examples of the inorganic fiber include glass fiber and rock wool.

By adsorbing and decomposing and eliminating odorous gas, volatile solvent gas or volatile organic compound, etc., a greater deodorizing property is realized, or excess moisture is absorbed and moisture is released during drying. In order to realize a more comfortable building space, as shown in FIG. 4, a woven fabric obtained by weaving or knitting a metal fiber, a synthetic fiber or a natural fiber with a breathable mesh as the base material 1 Using the ground or knitted fabric 10,
In addition, a configuration is proposed in which the deodorant humidity control layer 2 is formed by applying a required thickness from both sides of the woven or knitted fabric 10. In such a case, the woven fabric or knitted fabric 10 has such a mesh that the mutual deodorant humidity control layers 2.2 formed by coating from both sides with the woven fabric or knitted fabric 10 interposed therebetween can be integrally bonded. It is desirable that the mesh size is from about 2.5 mm square to a maximum of about 25 mm square, and the thickness of the deodorant humidity control plate material 3 of the present invention formed by coating is 9 mm or less. In the case of a thin fabric, the fabric or knitted fabric 10 to be used is made of a metal fiber or a synthetic fiber monofilament having a weaving degree of at least 1000 denier or the like and sufficiently imparted rigidity to improve the shape retention. Required from.

It should be additionally considered that the pores 20A held by the artificial zeolite powder 2A forming the deodorizing humidity control layer 2 are extremely fine, so that the odor gas, the volatile solvent gas, Although the adsorption of volatile organic compounds or the absorption of humidity is sufficiently performed, in order to positively absorb and absorb the odor gas and the volatile solvent gas or the volatile organic compounds generated and diffused in the building space and the moisture absorption, Odor control moisture layer 2
It is important to easily allow the water to pass therethrough and to allow moisture to pass therethrough. Since it is desired to form as many ventilation gaps 20B as possible, as shown in FIG. 10 to 3 of the amount of artificial zeolite powder 2A used for
It is preferable to mix and use 0% by volume of an inorganic foam 2E made of perlite, shirasu balloon or fly ash balloon. The particle size of the inorganic foam 2E is not particularly limited, but is very small. When the thickness is large, the finished finish of the deodorant humidity control layer 2 formed by coating deteriorates, so that the thickness is preferably 1.5 to 3.0 mm or less at the maximum.

The present invention is based on such a configuration. The following is a description of the results of experiments on the deodorizing properties and humidity control properties of the present invention. A stainless steel fabric having a mesh of 2.5 mm square and a mesh size of 2.5 mm square is used.
μm, the specific surface area is 80 m ² / g, the base substitution capacity (meg / 100 g) is 260 mg, the artificial zeolite powder having a pH value of 11.0 is 68%, the Portland cement is 7.0%, the dolomite plaster is 11.0. %capacity,
12% by volume of methylcellulose and 2.0% by volume of glass woven chopped strand were mixed with stirring, and then kneaded by adding 38% by volume of water to the total amount. Then, the coating material was applied to both sides of the
A deodorant humidity control plate having a thickness of 6 mm and a substantial thickness of 6 mm was used. In the deodorization test, an exhaust plug was provided at the lower part of the supply plug at the upper part of the closed type tank of 1 m ³ , and a deodorant humidity control plate 1 m ² was erected in the closed type tank. After the gas was filled and filled, the residual odor gas concentration in the tank was measured with a Kitagawa gas detector tube with the lapse of time, and the odor gas was allowed to come into contact with the deodorizing and controlling wet plate material in the tank. The gas was gently flown with a small fan, and the measurements were performed on six kinds of odor gases, such as ammonia, methyl mercaptan, hydrogen sulfide, acetic acid, carbon monoxide, and chlorine.

Further, in the humidity control test, 1 m ^{2 of a} deodorant humidity control plate material was appropriately disposed in the same closed type tank, and humidified air having a humidity of 98% was injected and filled from the supply plug, followed by the elapsed time. Measure the change in humidity to determine the hygroscopicity, and then inject into the tank 35% humidity dry air, fill and then measure the change in humidity rise in the tank with elapsed time to determine the moisture release Table 2 shows the results.

[0025]

As described above, the present invention can be applied to one side or both sides of a base made of an inorganic porous material having air permeability, or to both sides of a base made of a woven or knitted fabric. A wet layer is formed by coating, and the deodorizing and humidity controlling layer has an extremely large average particle diameter of 30 μm or less in contact surface area ratio for adsorption of odorous gas and the like, and has a specific surface area in order to maintain an extremely large adsorption capacity. Is at least 70 m ² / g, and a base substitution capacity (meg / 100 g) for decomposing and eliminating adsorbed odor gas molecules and volatile solvent gas molecules or volatile organic compound molecules by their base substitution properties.
Of artificial zeolite powder of 200 mg or more is 55 to 90
% In order to provide the deodorant humidity control layer with fixation and shape retention, and a fixing material composed of cement or dolomite plaster is added in a proportion of 7 to 25% by volume. In order to maintain toughness and adhesion to a wide range of adherends on the deodorizing humidity control layer, an adhesive composed of a cellulose derivative or sodium alginate is used in an amount of 3 to 2%.
Since it has a composition of 0% by volume, the odor gas, the volatile solvent gas or the volatile organic compound that has come into contact with the deodorizing humidity control layer is efficiently adsorbed, or the humidity that comes into contact with the excess humidity is efficiently taken away. Moisture is absorbed, and when the solidifying material is dried and solidified, a large number of ventilation voids are created due to the evaporation of moisture, and the material has air permeability and moisture permeability even when wrapped and adhered with an adhesive composed of a cellulose derivative or sodium alginate. Because the adsorptive property and hygroscopic property of the artificial zeolite powder are not impaired, the odor gas, the volatile solvent gas or the volatile organic compound is permeated from the deodorizing humidity control layer to the base material, so that these are positively affected. Odor gas molecules are absorbed and absorbed, and the adsorbed odor gas molecules and the like are decomposed and eliminated, so that the deodorizing property is maintained for a long period of time. The absorbed moisture is retained in the three-dimensional structure gap of the artificial zeolite powder and released according to the degree of drying, so that the humidity in the building space is stably maintained, so-called humidity control. To
As well as preventing the formation of condensation, the growth of bacteria and fungi is also suppressed,
In addition, the aggregation of unpleasant pests such as chain mites is suppressed, and a sanitary and comfortable building space is realized. In addition, the present invention has a deodorizing and humidity controlling layer mainly composed of an artificial zeolite powder having an enormous number of pores formed on a substrate made of an inorganic porous material, so that not only excellent heat insulating properties but also sound insulation is achieved. The present invention is an extremely suitable deodorizing and controlling wet plate material for solving a wide range of sick house syndromes.
