DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interior panel material for a building capable of maintaining a highly sealed living space, such as a middle-rise or high-rise apartment house or a detached house, safely and comfortably for a long period of time. About.

[0002]

2. Description of the Related Art In Japan, labor movement to urban areas has rapidly increased along with economic growth. Residential land supply has become tight in urban areas, resulting in soaring residential land. For this reason, in order to effectively use land in urban areas, a large number of medium- and high-rise apartment buildings with steel reinforced concrete structures are constructed and supplied. As a result, the small residential land has been constructed with a high building coverage ratio, and is in a densely forested state.

[0003] In a middle-rise high-rise house, an aluminum sash or an iron door is used in addition to a steel-framed reinforced concrete structure, so that the airtightness of a living space is extremely high. Needless to say, sound insulation, sound insulation and heat insulation for energy saving are required, and in detached houses, various designs and designs are required for each house. These detached houses also use aluminum sashes and aluminum opening doors, concrete panels and ceramic outer wall materials, as well as plywood and boards for interior materials. Hermeticity is significantly increased.

In addition, the interior materials of high-rise apartment houses or detached houses with high airtightness are made of synthetic resin plate materials in accordance with various tastes and values of residents, such as color, natural feeling, luxury and solid feeling. Plywood, gypsum board, cloth or synthetic resin or paper wall material or paint etc., and also as floor material, synthetic resin tile, synthetic fiber carpet, plywood material etc. are mainly constructed with synthetic resin adhesive etc. ing. However, since these living spaces have high sealing properties, as the use progresses, various building materials as well as adhesives and coatings for interior material adhesion and coating or chemical substances contained in the interior material itself, such as formaldehyde, etc. The so-called house-sick, in which the volatile gas is vaporized and stays in the living space, causing physical illness of the resident, has been raised as a major social problem. In addition, the living odor tends to be muffled with the increase in the airtightness of the living space, and the living odor adheres to and penetrates the interior materials, etc., and becomes a more uncomfortable living space. Bacteria and fungi are liable to propagate due to the humid and warm environment throughout the year due to the surrounding facilities. Pest carcasses are a major cause of allergic diseases, forcing them to live in extremely unsanitary living spaces. Further, in such a living space, even with a slight humidification method during the winter drying, dew condensation occurs on the inner wall surface and the window glass, and the corrosion deterioration of the building and the propagation of fungi increase. Energy must be used for cooling and dehumidification.

In view of such a problem, the inventor has already made inorganic materials having a particle size of 30 μm or less and a radiation wavelength of 2.about. Electromagnetic waves in the near infrared region of 7 to 3.2 μm and in the far infrared region of 5.0 to 7.4 μm have an electromagnetic radiation ceramic powder material having an emissivity of at least 0.8 or more with respect to the emissivity of the black body. % By weight or more, and kneaded with water to solidify and mold into a required shape, or to sinter the solidified molded product at a temperature of 900 ° C. or less. 3469
No. 57.

However, in the prior application, when the material used is cement, the solidified molded product retains practical strength but is inferior in moldability of a thin material, and is required to have aesthetics and dimensional accuracy like interior materials. In addition, materials such as gypsum and clay not only take an extremely long time to dry during solidification and molding, but also generate a lot of distortion and deformation due to drying, and heating for a long time also during firing. Gradient and firing time are required, and if the temperature drop gradient is not strictly controlled, cracks are frequently generated and damaged, and extremely large firing furnaces are required for wide products such as interior materials. There are many problems in terms of technology and cost. In addition, in recent years, since zeolite ore is porous and retains base substitution properties, attempts have been made for interior plate materials using the zeolite ore as a raw material. However, zeolite ore is usually made of clay mainly composed of montmorillonite in its composition. Since the clay material absorbs water and swells due to moisture absorption and self-disintegrates as it contains a large amount of material, the interior plate material and the like once become a fine powder and then added with water to impart viscosity and plasticity, It must be solidified and formed into a desired shape, and then dried and fired, which is ultimately hampered by the problems in practical production as described above.

[0007]

SUMMARY OF THE INVENTION In view of the above problems, the present invention has been intensively studied, and as a result, the composition and performance of zeolite ore produced in an extremely wide area are significantly different depending on the production area. First, in order to positively adsorb and decompose the chemical volatile gas and odor in the living space, the specific surface area is at least 15 m ² / g or more, and the base substitution capacity (meq / 100 g) is 150 mg.
The above-mentioned thing is preferable, and it is possible to exhibit the so-called humidity control of moisture absorption and drying during drying and moisture absorption at the time of high humidity, and the composition composed of the zeolite crystal and the volcanic glass material in the composition, And a Mohs hardness of about 4.8 to 5.8, which has high toughness and high specific toughness, can be obtained by using a specific diamond grain blade. The present invention has been investigated to be able to cut and produce the product directly into a thin wall and efficiently with a required area, and that the zeolite ore has extremely excellent adhesion to cement, gypsum, clay or diatomaceous earth. Reached. That is, the present invention can be easily constructed as an interior plate material in a highly enclosed living space, and actively absorbs and decomposes chemical volatile gases and odors, and also absorbs excessive moisture in the living space to suppress or prevent the growth of fungi. And
An object of the present invention is to provide an inexpensive architectural interior panel material that can create a safe, comfortable and hygienic living space for a long period of time.

[0008]

The technical means used by the present invention to solve the above-mentioned problems is that a zeolite crystal having a composition of clinoptilolite or mordenite and a quartz, feldspar, feldspar or the like are used. The water resistance of the vitreous component is maintained, and the specific surface area is at least 15 m ^2.
/ G or more and the base substitution capacity (meq / 100 g) is 15
A zeolite ore having a Mohs hardness of 4.8 to 5.8 and a diameter of 0.5 to 2.0 is used.
Using a diamond cutter, diamond band saw, or diamond wire saw having a diamond grain blade with diamond grains of 1 mm, water-cooling is performed and at least its thickness is at least 3 mm while washing and flowing out the dust accompanying the cutting. In this case, a zeolite plate material having an appropriate area is cut and formed, and then dried by a suitable drying means so that the residual moisture content becomes 3.0% or less. In addition, since the interior paneling material for building is required to have a variety of design preferences and values of the occupants used on the one hand, when cutting one side of the zeolite plate material formed by cutting, The cutting surface is cut relatively smoothly using a diamond cutter, diamond band saw, or diamond wire saw with a diamond grain blade in which small diamond grains are implanted. A configuration in which the cut surface is cut and formed by cutting with a diamond cutter, diamond band saw or diamond wire saw with an implanted diamond grain blade, and one side of the cut and formed zeolite plate material is further polished for smoothness. And a zeolite plate cut and formed at a temperature of 400 to 9
It is configured to calcine at an appropriate temperature of 00 ° C. to change the overall color tone of the zeolite plate material to a milky white light brown color.

Further, according to the present invention, chemically volatile gas that stagnates and stays in a highly sealed living space and odor gas that diffuses in the air can be safely decomposed and eliminated over a long period of time, and the propagation of floating bacteria and fungi can be prevented. In order to prevent suppression, at least one side surface of the zeolite plate has an emission wavelength of 2.7 to 3.2.
The near-infrared region of μm and the radiation wavelength of 5.0 to 7.
Electromagnetic radiation ceramic fine powder that can emit 4μm electromagnetic wave in the far infrared region with an emissivity of 0.8 or more with respect to the emissivity of black body is mixed and dispersed with water using cement, gypsum, diatomaceous earth or clay as binder In addition, a coating layer is formed by coating and drying so that the electromagnetic radiation ceramic fine powder is applied at a rate of 0.1% by weight or more based on the weight of the zeolite plate material.

[0010]

The present invention using the above technical means has the following functions. That is, since the composition of the zeolite ore used is composed of a crystalline body composed of clinoptilolite or mordenite and a volcanic glass component such as quartz, feldspar, or feldspar, water resistance that does not swell and collapse even when absorbing a large amount of moisture or water. Since it retains its properties and its cleavage is extremely small, it can be mined in a desired cubic shape at the time of mining. And this zeolite ore has a specific surface area of at least 15 m ² /
g of porosity and its base substitution capacity (meq / 10
0g) has a high base substitution property of 150 mg or more and also has a Mohs hardness of 4.8 to 5.8, so diamond grains having a diameter of 0.5 to 2.0 mm are implanted. Zeolite ore directly with a diamond cutter, diamond band saw, and diamond wire saw using a diamond grain blade, and without damaging the zeolite plate material having a small thickness of about 3 mm and an appropriate area with a uniform cut surface. Cutting can be performed efficiently. Furthermore, by using diamond grains having different diameters, it is possible to freely change the roughening and densification of the cut surface, and since the Mohs' hardness is 4.8 to 5.8, polishing of the cut surface is also possible. It is easy to apply, smoothness is enhanced by polishing, gloss is imparted, and a light ripple pattern peculiar to natural stone appears, and the cut zeolite plate is calcined at an appropriate temperature of 400 to 900 ° C. As a result, the color tone of the base color of the material, such as milky white and light green, can be changed to light brown. In addition, since the zeolite plate itself retains high impregnation with cement gypsum, diatomaceous earth, clay, etc.,
At the time of construction, the construction can be extremely easily performed by the base treatment.

Since the present invention, which is constructed on a ceiling, a wall, or a floor of a living space, is a thin plate, the chemical volatile gas is volatilized and stays there, or the odorous gas is diffused or the air containing moisture is mixed. It has a large contact area, and has a large specific surface area and is highly porous and retains a high base substitution property, so that the chemical volatile gas and odorous gas are positively adsorbed, and the base substitution property also prevents decomposition and prevents excess decomposition. Moisture is temporarily absorbed and released as the humidity decreases. Further, in the case where the coating layer of the electromagnetic wave radiating ceramic fine powder is formed on at least one side of the present invention, the electromagnetic wave which effectively excites the water molecule with the absorption of the external temperature energy is re-emitted, and the water molecule in the air is removed. When excited, singlet oxygen, superoxide, hydroxy radical, hydrogen peroxide, and other reactive oxygen having high reactivity and oxidative decomposition power repeat excitation generation and base decay, so that not only decomposition and elimination of chemical volatile gas and odor gas, The intracellular moisture of floating bacteria and fungi is denatured, and physiological functions are inhibited. And since such a coating layer is coated using cement, gypsum, diatomaceous earth or clay as a binder, it does not affect the performance of the zeolite plate material such as gas adsorption and moisture absorption / desorption.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view for explaining a method of forming a zeolite plate according to an embodiment of the present invention; FIG.
FIG. 3 is an enlarged explanatory view of a diamond grain blade, and FIG. 3 is a perspective view of the present invention. The zeolite ore 1 used in the present invention has a zeolite crystal composed of clinoptilolite or mordenite because of its usage characteristics. And a volcanic vitreous component composed of quartz, feldspar, or feldspar, etc., to maintain water resistance without self-disintegration or change in basic physical properties even when exposed to a large amount of moisture or water over a long period of time. Naturally, a large width and a long length are required for use. Therefore, it is necessary to cut and form a zeolite ore 1 having a relatively large mass and to have a small cleaving property. It is preferable that clay, lime or other ores are not mixed in.Moreover, in the case of practical use, it is necessary to positively adsorb the chemical volatile gas and odor gas in the highly sealed living space. A specific surface area of at least ^15m 2 /
g or more of the volatile gas and odorous gas adsorbed and adsorbed and decomposed and fixed, and the base substitution capacity (meq / 100 g) is at least 150 mg.
The above are selected.

Further, in the present invention, the zeolite ore 1 is directly cut to a required thickness and area. In practical use, the thickness is relatively thin at most about 3 to 30 mm. When cutting to a required area with such a thin wall, it is necessary to have a hardness that does not cause damage or breakage at the time of cutting, and on the other hand, to efficiently supply a large amount of interior material, Since it is necessary to cut and form it, its Mohs hardness is preferably about 4.8 to 5.8. Therefore, as a specific example of the zeolite ore 1 satisfying such conditions, it is mined from a green tuff mining area, and its true specific gravity is approximately 1.9 to 2.4.
Silicon oxide as its average chemical composition.
7%, aluminum oxide 11.9%, potassium oxide 3.
5%, sodium oxide 2.6%, calcium oxide 0.6
%, Iron oxide 0.55%, magnesium oxide 0.25%,
Manganese oxide 0.06%, phosphorus pentoxide 0.03% and other ignition loss 5.8% by weight.

When cutting the zeolite ore 1 thus selected, it is required to have a thickness of about 3 to 30 mm for practical use because of its light weight and simplicity of construction work. Since the hardness is 4.8 to 5.8, a cutting device 2 such as a diamond cutter 20, a diamond band saw or a diamond wire saw (not shown) having a diamond grain blade 2A of the highest hardness is used for efficient cutting. Can be In such a case, the diamond grain blade 2A usually has a diamond grain 2 having a required grain size on the outer surface of a base material 2B made of a metal material having a good workability such as brass.
C is planted in an exposed state with a required density.
The diamond grain blade 2A is mounted and fixed to the tip of the blade. What is essential for cutting is that the front surface 3A and the back surface 3B of the zeolite plate material 3 formed by cutting correspond to the cut surface, and the cut surface is used as it is or further polished to make it even smoother. In the case where the cut surface is cut and finished in a dense and smooth shape, as in the case where the cut surface is used with imparting properties and gloss, or in the case of thin cutting, when cutting friction resistance is greatly added, cutting is performed. Not only is the surface rough, but zeolite plate 3
This may result in damage or breakage of the surface, and on the other hand, when forming a relatively rough cut surface or forming uneven cut surfaces etc. to improve the adherence to the underlying ground such as cement or mortar during construction, It is desirable to add a large cutting frictional resistance. Therefore, when the cut surface needs to be dense and smooth, the diameter of the diamond grain 2C implanted on the diamond grain blade 2A is preferably about 0.5 to 1.0 mm, and the cut face is rough. Alternatively, when irregularities are required, the diameter of the diamond grains 2C is set to 1.0 to 2.0 mm.
It is desirable to use a large one. In addition, at the time of cutting, since the diamond grain blade 2A rotates or moves at a high speed and generates a large amount of frictional heat, it should also be noted that cooling by water is always performed and washing and outflow of dust generated along with the cutting is performed.

The zeolite plate material 3 thus cut to a required thickness has its outer edge cut and removed in order to finish it to a required width and length, and is usually heated and dried to remove water absorbed by the addition of water. The product 4 of the present invention is formed by drying such that the residual moisture is 3% or less, preferably 1% or less by such a drying means. In such a case, there is no particular limitation on the drying means, but if the drying is performed at an excessively high temperature, the color tone changes due to the calcining action. Therefore, the drying temperature should be limited to 180 to 200 ° C. or less. . FIG. 4 is an explanatory cross-sectional view of the product 4 of the present invention when the cut surface serving as the front surface 3A is cut densely and smoothly, and the cut surface serving as the back surface 3B is cut into a rough surface. The product 4 of the present invention is used as an interior plate for a building, and the interior material is required to have various colors and designs. For this reason, in the product 4 of the present invention, as shown in FIG. 5, the surface 3A of the zeolite plate 3 is polished with a buff material or an abrasive material made of an appropriate metal material to impart smoothness and gloss to the surface 3A. With the impartation of smoothness and luster, it is possible to produce a milky, pale green, flowing pattern peculiar to the zeolite ore 1. Further, the zeolite plate 3 is calcined at an appropriate temperature in a temperature range of 400 to 900 ° C. It is also proposed to change the color of milky pale green which is the basic color of zeolite ore 1 to milky pale brown due to the burning off of the ignition loss in the composition and the heat denaturation of potassium oxide, sodium oxide or phosphorus pentoxide. In such a case, if the calcination temperature exceeds about 450 ° C., the base substitution property is gradually impaired. Therefore, calcination in a low temperature range is desirable, and if it exceeds 900 ° C. Since the problem extends to melt such as a basic physical properties of the mountain glassy worth it should be noted.

FIG. 6 is an explanatory view of the present invention in which a coating layer of a ceramic powder radiating electromagnetic waves is formed. The present invention is applied to a ceiling, a wall, or a floor of a highly sealed living space, and is chemically vaporized. In order to adsorb gas and odor gas and decompose and fix or decompose or remove excessive moisture, the specific surface area is at least 15 m ² /
g or more and base substitution capacity (meq / 100g)
Is used to cut the zeolite ore 1 having a weight of 150 mg or more into a zeolite plate material 3 and adsorb and decompose the chemically volatilized gas and odor gas diffused in the air in contact with the surface of the present invention. Although it is fixed and disassembled and erased, the air inside the living space with high airtightness is insufficient, so the chemical volatile gas and the odorous gas that are volatilized in the living space are completely and quickly disassembled and fixed. It is not yet a sufficient means for dismantling or decomposing. Therefore, according to at least one aspect of the present invention, a near-infrared region having a wavelength of 2.7 to 3.2 μm, which absorbs external temperature energy and serves as a resonance wavelength of water molecules, and a wavelength of 5.0 to 7.4 μm, which is a wavelength of 5.0 to 7.4 μm. An electromagnetic wave radiating ceramic fine powder 40 capable of radiating an electromagnetic wave in the far-infrared region and having an emissivity of at least 0.8 or more with respect to the emissivity of a black body is substantially used for the weight of the zeolite plate 3. 0.1
% By weight of cement, gypsum, diatomaceous earth or clay, which has an adhesive property to the zeolite plate material 3 and also has air permeability and moisture permeability, as a binder 40A, and is dried at a required thickness. Means for forming the deposition layer 4A is proposed.

That is, water molecules have wavelengths of 2.7 to 3.2.
Since it has an infrared absorption so-called resonance wavelength band in a near-infrared region of μm and a far-infrared region of 5.0 to 7.4 μm, a small amount of radiant energy can be obtained by emitting electromagnetic waves having a wavelength suitable for the resonance wavelength band. This effectively excites water molecules in the air in the entire living space in which the chemical volatilized gas volatilizes and stays or the odor gas diffuses and mixes or the fungi float, and the water molecules are excited by singlet oxygen, superoxide, and hydroxyl radicals. Alternatively, active oxygen having a high reactivity such as hydrogen peroxide and oxidative decomposition power is created, and the active oxygen is combined with a chemical volatile gas or an odor gas instantaneously to decompose and eliminate, and further denatures fungal cell water. As a result, propagation is prevented by inhibiting the physiological function. In such a case, several types of electromagnetic radiation ceramic fine powders 40 that can be used are proposed, but specific examples include silicon oxide 50%, aluminum oxide 26%, titanium oxide 11% as a transition element oxide, oxide Manganese 8
% And zinc oxide at a weight ratio of 5%, and then sintered at a temperature of about 920 to 960 ° C., so as to increase the surface area ratio of electromagnetic wave radiation.
To about 10 μm. The coating layer 4A formed on at least one side surface of the zeolite plate 3 can be formed by various methods such as a spraying method, a coating method, and a roll coating method. The layer 4A does not impair the porosity, the base substitution property, and the moisture absorption / desorption property of the zeolite plate material 3, and is to be firmly attached and held for a long period of time. This is because zeolite plate 3
A cement having a strong adhering property and air permeability
Gypsum, diatomaceous earth, or clay may be used as the binder 40A, and the electromagnetic radiation ceramic fine powder 40 and water may be mixed and dispersed in an appropriate ratio, applied as a coating liquid having a viscosity suitable for the coating means, and dried. In this case, it should be noted that, in order to decompose and remove chemical volatile gas and odorous gas, or to prevent the propagation of fungi, the coating amount of the electromagnetic radiation ceramic fine powder 40 with respect to the weight of the zeolite plate 3 is substantially reduced. The purpose is to apply the coating at a weight ratio of 0.1% or more.

[0018]

Water resistance that does not collapse, has extremely low cleavage properties, has a specific surface area of at least 15 m ² / g, and has a base substitution capacity (meq / 10
0g) is 150 mg or more, and zeolite ore having a Mohs hardness of 4.8 to 5.8 is used, so that it can be mined as a zeolite ore block having a desired size and a diamond having a diameter of 0.5 to 2.0 mm. The thickness is 3m directly by using diamond grain blade with grain
m can be efficiently cut and formed as a zeolite plate material of m or more, which not only enables mass production and inexpensive provision, but also has a plate-like shape, which is chemically volatilized by being appropriately stretched on ceilings, walls, floors, etc. of living spaces. A large contact area with the air in the living space where the gas volatilizes and stays or the odor gas diffuses and mixes is formed, and therefore, due to the extremely large porosity of the specific surface area,
These are physically adsorbed and chemically decomposed and fixed or decomposed and erased due to their high base substitution. Further, the zeolite plate material absorbs and desorbs moisture by about 10 to 15% due to its zeolite crystal and porosity. To have an effect
The humidification is avoided, the growth of bacteria and fungi is suppressed, and a comfortable living space is maintained. In addition, the present invention
It is non-flammable with fire resistance of 000 ° C or higher, and has excellent heat insulation and excellent sound insulation due to its porosity. In addition, it is possible to easily create smoothness and gloss by polishing the surface or the back surface of the cut surface by making use of the diamond grain blade at the time of cutting. Can also be used as a decorative material, and the color tone can be changed by calcination, so it can be used as interior materials of various colors and designs. Further, in the case where a coating layer using a ceramic powder radiating electromagnetic waves is formed on at least one side of the present invention, water molecules in the entire living space are excited by the radiating electromagnetic waves, and the reactivity is high and the oxidative decomposition power is increased. Active oxygen is created, the chemical volatile gas and odorous gas are decomposed and eliminated, and the physiology of suspended bacteria and fungi is inhibited, and propagation is prevented. Such effects are permanently caused by the presence of temperature energy. Since it is exhibited, it can be said that it is an architectural interior plate material having extremely many features, such as a safe and comfortable living space that can be maintained safely over a long period of time.
