DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can safely and efficiently deodorize and disinfect odors which are diffused and mixed in air in a living space or a facility space, or contaminated air in which various fungi float. It relates to a deodorant and antibacterial granular substrate.

[0002]

2. Description of the Related Art In recent years, health orientation has been remarkably increased in conjunction with the improvement of living standards, so that hygiene and comfort have been improved not only in living spaces but also in workplaces, stores and various types of customer collection facilities. There is a strong demand for this, and thus, in living spaces and various types of facility spaces, deodorization and removal of odors and antibacterial action of various fungi have become new issues.

[0003] By the way, as deodorant means at present,
Starting with methods of masking odor molecules with an aromatic gas stronger than the odor that diffuses, methods of chemically decomposing odor molecules with fluorine, ozone gas, zinc acid, etc., methods of adsorbing odor molecules in porous materials, or microorganisms There have been proposed methods of decomposing odor molecules with enzymes generated by the method.However, the masking method not only has a preference for dislike or dislike of the aromatic gas itself, but depending on the odor, the synthetic odor turns into odor instead There is a risk, or the method of using a gas or chemical such as fluorine, ozone gas or chlorite is limited to use in an industrial closed compartment because of the danger, and even the method of adsorbing to a porous material The adsorption and deodorization effect is lost in a short time due to the adsorption of odor molecules, etc. There has been a problem such as flame Kashii.

On the other hand, as an antibacterial means against fungi floating in the air, phenolic compounds, pyridine compounds, amide compounds, benzimidazole compounds or carbamate compounds as well as phenols having a chemical killing property are mixed with paints. After the filter is applied to the interior of the living space or facility space or stretched, or the chemical agent is attached to the nonwoven fabric or glass wool, etc. Attempts have been made to circulate and distribute antibacterial substances, but when used as paints or interior materials, the contact ratio with the entire contaminated air in the space is extremely small, and the antibacterial properties of such chemical agents are a component of the killing component The antibacterial effect cannot be expected because the effect is exhibited by the elution or volatilization of If the was circulated polluted air,
Effective antibacterial methods have not yet been realized in living spaces and institutional spaces because, for example, there is a risk that the eluted or volatilized drug killing components may fill the space and cause significant danger.

[0005] As a result of repeated studies in view of such circumstances, the inventors have found that moisture as moisture exists in contaminated air in living and facility spaces where various odor molecules diffuse or fungi float. Effectively exciting water molecules to produce active oxygen having high reactivity and oxidative decomposition power such as singlet oxygen, superoxide, hydroxyl radical or hydrogen peroxide, and active oxygen generated from water molecules. Is extremely safe, and by using the active oxygen in combination with an adsorbent capable of physically adsorbing odor molecules and fungi, it can eliminate odor molecules and inhibit the physiological function of fungi and prevent the growth of fungi. Have been found to increase remarkably, and have led to the present invention.

[0006]

That is, the present invention is to solve the problem of odor molecules by eliminating odor molecules by contacting and circulating a large amount of contaminated air in a living space or facility space where odor molecules diffuse or fungi float. An object of the present invention is to provide a deodorant and antibacterial granular base material that can efficiently perform antibacterial action on odors.

[0007]

The technical means adopted by the present invention to solve the above-mentioned problems is to remove various odor molecules and fungi which diffuse or float in polluted air in a living space or a facility space. A zeolite selected as an adsorbent having a viscosity and plasticity that retains an adsorption capacity capable of physically adsorbing a large amount and can be formed into an appropriate shape, dissolves odor molecules, and inhibits physiological functions of fungi And to generate active oxygen having high oxidative decomposition power from water molecules in the contaminated air, which has high reactivity for preventing propagation, the emission wavelength is 2,
5 to 3, 2 μm near-infrared ray and emission wavelength of 5, 0
The emissivity of a far-infrared electromagnetic wave of 7 to 4 μm can be emitted with an emissivity of at least 0, 8 or more with respect to the emissivity of a black body, and the particle size is 1 to 100 to increase the radiation efficiency.
The maximum particle size of zeolite, which is composed of a ceramic powder material with electromagnetic radiation of μm and forms the adsorbent, is 5 mm.
Crushed below and 1/10 to 1/15 of this maximum particle size
10-45% of zeolite crushed to fine particle size
The adsorbent is constituted by a particle size distribution that is a weight ratio, and the zeolite is used in a manner such that the electromagnetic radiation ceramic powder is 0,
After blending at a weight ratio of 3 to 3.0% and adding an appropriate amount of water to give finely crushed zeolite viscosity and plasticity, it is formed into granules of required shape and size, and zeolite adsorption performance And calcined at a temperature of 300 ° C or less, and a zeolite crushed to a maximum particle size of 5mm or less is mixed with kaolin clay, smectite clay or sepiolite clay in a weight ratio of 10 to 45%. In addition, the electromagnetic radiation ceramic powder material is added in a weight ratio of 0, 3 to 3, and 0%, and an appropriate amount of water is added to impart viscosity and plasticity to the clay to form a granule of an appropriate shape and size. The present invention is based on the concept of forming and firing at a temperature of 300 ° C. or less so as not to impair the zeolite adsorption performance.

[0008]

The present invention having the above configuration has the following operation. That is, the zeolite used as the adsorbent has extremely fine pores capable of adsorbing and capturing odor molecules and fungi.
Since it is formed with a porosity of 0 to 50%, a large amount of odor molecules and fungi in the contaminated air flowing through the contact flow are adsorbed and captured, and the zeolite contains sodium oxide, calcium oxide, potassium oxide, It contains about 5 to 6% of magnesium oxide and the like, and has a particle size distribution in which 1/10 to 1/15 of finely crushed zeolite has a weight ratio of 10 to 45% with respect to the crushed maximum particle size. Therefore, by adding an appropriate amount of water, the finely crushed zeolite retains viscosity, can be kneaded well with the electromagnetic radiation ceramic powder material, and is given a plasticity to form particles of a required shape and size. It can be easily formed.
Furthermore, even when 10 to 45% by weight of smectite clay or sepiolite clay is used in place of kaolin clay instead of finely crushed zeolite, the clay retains viscosity by adding an appropriate amount of water. Thus, kneading with the electromagnetic radiation ceramic powder material is improved, and plasticity is imparted, so that it can be easily formed into granules having an appropriate shape and size.

Then, the mixture is kneaded with an adsorbent made of zeolite and an electromagnetic radiation ceramic powder or with clay and formed into an appropriate shape and size.
The hard deodorizing and antibacterial granular base of the present invention in which finely crushed zeolite or clay that retains viscosity due to firing at a temperature of not more than ℃ solidifies and the adsorbent and the electromagnetic radiation ceramic powder material are firmly bound As the material is formed, the firing temperature is also lower than 300 ° C., so that the fine and porous structure of zeolite is not impaired, and even when clays are used, many micropores are formed by firing. Adsorption of odor molecules and fungi is maintained.

In addition, the fired deodorant and antibacterial granular substrate of the present invention has a near-infrared ray having a radiation wavelength of 2, 5 to 3, 2 μm and a far-infrared ray having a radiation wavelength of 5, 0 to 7, 4 μm. An electromagnetic wave radiating ceramic powder material having a particle diameter of 1 to 100 μm is used so that the electromagnetic wave has an emissivity of at least 0, 8 or more with respect to the emissivity of the black body, and has a large emission surface area ratio. % By weight, water molecules in the contaminated air flowing near the deodorant and antibacterial granular substrate of the present invention are effectively excited by the radiated electromagnetic waves to generate active oxygen. .

Since the deodorant and antibacterial granular base material of the present invention is formed in a granular form having an appropriate shape and size, it is usually filled in a suitable air-permeable filling frame and used for contamination. The air is circulated, and a large number of filling intervals are formed due to the filling of the particulate matter, and the contaminated air flows through the large number of filling intervals while contacting the outer surface of the granular material, and enters the pores. Means that a large amount of odor molecules and fungi are adsorbed and captured.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an explanatory view of the present invention comprising zeolite and ceramic powder radiating electromagnetic waves. The present invention is applied to a living space or a facility space. Maintained physical adsorption of odor molecules and fungi and active oxygen generation function in order to efficiently deodorize and antibacterial by contacting and circulating a large amount of contaminated air in which various odor molecules diffuse or fungi float. A technical concept is used in which a granular material is filled, and contaminated air is circulated through a filling gap of the filled granular material for deodorization and antibacterial. Therefore, zeolite is selected as a material of the adsorbent 1 which has a fine and large adsorption capacity capable of adsorbing odor molecules or bacteria and has viscosity and plasticity for forming into a required shape and size.

That is, zeolite has a very large adsorption capacity because the pores capable of adsorbing odor molecules or bacteria are approximately 40 to 50% per unit volume and the so-called porosity is as high as 40 to 50%. In addition, since the composition component contains 5 to 6% by weight of a component that creates viscosity by mixing with water, such as sodium oxide, calcium oxide, potassium oxide, etc., it has plasticity and has an appropriate shape and size. This is because the granules can be easily formed.

The zeolite as the adsorbent 1 is formed in an appropriate shape from an extremely small granular material to an extremely large granular material according to the purpose of use. Therefore, it is desired that the electromagnetic radiation ceramic powder material 2 to be blended is made and dispersed uniformly throughout the adsorbent 1.
It is important that the maximum particle size be 5 mm or less. More importantly, the kneaded zeolites and the electromagnetic radiation ceramic powder 2 to be mixed are kneaded with each other to form an appropriate shape and size. And that the surface area ratio is increased to impart viscosity and plasticity with sodium oxide, calcium oxide, potassium oxide or magnesium oxide having miscibility with water, and zeolite mutual or electromagnetic radiation ceramic powder material 2 by firing.
From the maximum particle size of the zeolite, the particle size distribution is such that the finely crushed zeolite 1A having a particle size of 1/10 to 1/15 is 10 to 45% by weight. To configure.

[0015] Viscosity and plasticity for kneading the crushed zeolites with each other and the compounded electromagnetic wave radiating ceramic powder 2 to form them into an appropriate shape and size, or mixing the zeolite and the electromagnetic wave radiating ceramic powder 2 with each other. As a means for firmly fixing by firing, as shown in FIG. It is also proposed to use 10 to 45% by weight of the total weight. That is, since these clays 1B also contain, as a main component, magnesium oxide, calcium oxide, sodium oxide or potassium oxide having miscibility with water, in addition to silicic acid and alumina, the viscosity and plasticity can be increased by an appropriate amount of water. This is because the zeolite and the electromagnetic wave radiating ceramic powder material 2 are firmly fixed by sintering together with the sintering, and a large number of micropores are formed by the sintering.

The amount of water added to impart viscosity and plasticity using finely crushed zeolite 1A or clay 1B depends on the maximum particle size of the zeolite forming adsorbent 1 It depends on the mixing ratio of the crushed zeolite 1A or clay 1B, and the shape and size of the formed zeolite 1A or clay 1B. Preferably, about 15 to 30% of the total amount of the adsorbent 1, the electromagnetic radiation ceramic powder 2 and the finely crushed zeolite 1A or 1B is generally used.

The electromagnetic wave radiating ceramic powder material 2 for generating active oxygen effectively excites the water molecules in the contaminated air, and has a radiation wavelength in the range of the resonance wavelength region of the water molecules. A near infrared ray of 5 to 3, 2 μm, and a far infrared ray having a radiation wavelength of 5, 0 to 7, 4 μm at a high emissivity of at least 0, 8 with respect to a so-called black body
What emits with the above emissivity and strong energy is used. By the way, it has long been known that ceramics have a far-infrared radiation characteristic as an electromagnetic wave radiation material.For this reason, ceramic materials containing alumina, titania or zirconia as a main component radiate far-infrared rays, and the transparency of the heat rays is increased. Industrial dryers and cookers for business use have come to market.

The electromagnetic radiation ceramic powder material 2 used in the present invention has an electromagnetic wave in the near infrared region having a radiation wavelength of 2, 5 to 3, 2 μm and a far infrared region having a radiation wavelength of 5, 0 to 7, 4 μm. It is necessary to emit electromagnetic waves stably with an emissivity of at least 0, 8 or more to the emissivity of the black body. Since the radiation is weak, it is necessary to re-radiate the light as efficiently as possible.

That is, the electromagnetic wave radiating ceramic powder material 2 of the present invention has a radiation wavelength of 5, 0 to 7, 4
It is preferable to use silicon oxide and aluminum oxide as main components in order to emit electromagnetic waves in the far infrared region of μm with a high emissivity, and it is preferable that silicon oxide is 1 and aluminum oxide is 0, 7 to Something about 0, 9 is proposed. And the other emission wavelengths 2, 5 and 3 for effectively exciting water molecules,
As means for increasing the emissivity of electromagnetic waves in the near-infrared region of 2 μm, it is proposed that a transition element oxide is further added to the main component. Coal oxide, iron oxide, titanium oxide, manganese oxide, nickel oxide or copper oxide, etc. are taken into consideration in terms of surface and supply stability or workability,
By blending at least two kinds of the transition element oxides, it is possible to stably radiate the radiated electromagnetic wave at a high emissivity. To 55% by weight.

Further, the emitted near-infrared and far-infrared electromagnetic wave energies are weak because they depend on external temperature energy, and therefore are re-emitted from the viewpoint of exciting water molecules to generate active oxygen. It is necessary to take measures to further increase the electromagnetic wave energy and to radiate this more efficiently. For this purpose, it is preferable to interpose a catalyst having a function of absorbing weak external temperature energy and promoting an electron transfer reaction for conversion to near-infrared or far-infrared electromagnetic waves, and the catalyst is zinc oxide. And noble metals such as silver and platinum are selected, and the catalyst is blended in a weight ratio of 0, 3 to 10% with respect to the main component and the transition element oxide.

Since the electromagnetic wave radiating ceramic powder material 2 re-radiates near-infrared and far-infrared electromagnetic waves with the absorption of external temperature energy, in order to radiate the electromagnetic waves efficiently, the external temperature energy must be reduced. It is desirable to increase the absorption surface area ratio and the electromagnetic wave emission surface area ratio. This is why the electromagnetic wave emission ceramic powder material 2 is fired into fine particles having a particle size of 1 to 100 μm.

Thus, the zeolite as the adsorbent 1
Zeolite 1A or clay 1 crushed to a fine particle size of 1/10 to 1/15 of the maximum particle size of the zeolite
B is blended at a required ratio, and further, the electromagnetic wave radiation ceramic powder material 2 is blended at a weight ratio of 0, 3 to 3, and 0% based on the total weight thereof. In such a case, if the mixing ratio of the electromagnetic radiation ceramic powder material 2 is less than 0.3% by weight, the deodorizing and antibacterial effects cannot be expected sufficiently, and the mixing ratio increases to 3.0% or more. No difference in deodorant or antibacterial effect was observed.

In order to form the present invention, an appropriate ratio of water is added to the raw materials blended in the required blending ratio, and the zeolite 1A or the clay 1B crushed to a fine particle size blended in the raw materials. The mixture is sufficiently kneaded while maintaining sufficient viscosity and plasticity, and then molded into a granular material having an appropriate shape and size by an appropriate molding machine. By calcining at a temperature of 250 ° C., the product 3 of the present invention is firmly calcined and solidified together with evaporation of moisture. The reason why the firing temperature is limited to 300 ° C. or less in such a case is to sufficiently evaporate and remove the moisture in the fine and porous zeolite and to protect the fine and porous structure from thermal destruction.

The product 3 of the present invention formed by firing is formed into granules having an appropriate shape and size according to the purpose of use. Generally, a product having a spherical shape 3A as shown in FIG. 3 is used. It is also advantageous during molding and firing, but it has a cylindrical 3B
Any suitable shape such as a hexagonal columnar shape or a hexagonal columnar shape 3C can be used as long as it is granular. Thus, when the product 3 of the present invention is used for deodorizing and antibacterial in a living space or a facility space, as shown in FIG. 4, the material 3 is made of a coarse and tough material that does not leak the product 3 of the present invention. The present invention 3 is filled in the formed filling frame 4 having an appropriate shape, and the contaminated air is filled by using a blowing means such as an air conditioner. It may be distributed and circulated.

[0025]

As described above, according to the present invention, most of the material for forming the material is fine and porous, and the porosity thereof is 40 to 50%.
Even when zeolite is used, or when clay is used to impart viscosity and plasticity during molding, a large number of micropores are formed by firing, so that the adsorption capacity as an adsorbent is extremely large. In this adsorbent, an electromagnetic radiation ceramic powder material that effectively excites water molecules in contaminated air to generate active oxygen is dispersed throughout, and is fired and formed into granules of an appropriate shape and size. Therefore, not only is it extremely strong and lightweight, so it is convenient to handle, but also, since a large amount of the present invention is filled in the filling frame and the contaminated air is circulated during use, the contaminated air is used by the present invention. Is distributed and circulated through the filling gap portion, so that not only a large amount of contaminated air can be circulated, but also the contaminated air can be dispersed and distributed in many filling gap portions according to the present invention. For circulating while in contact with the outer surface of the timber, the odor molecules and fungi in the contaminated air is heavily adsorbed capture fine 且多 pore microporous inside. When contaminated air flows near the outer surface of the present invention or in the filling gap between the present invention, water molecules of water in the contaminated air are excited by the emitted near-infrared and far-infrared electromagnetic waves to generate active oxygen. Therefore, odor molecules in contaminated air are instantaneously decomposed and eliminated by the active oxygen, and the inhibition of physiological functions due to denaturation of intracellular water content and the propagation of suspended fungi are prevented by the oxidative decomposition power. The contaminated air in the natural space is also deodorized, antibacterial and purified in a short time. Further, the odor molecules adsorbed and trapped in the fine pores of the adsorbent are sequentially decomposed and eliminated by the generated active oxygen, so that the adsorption and trapping ability of the odor molecules is maintained for a long time, and the propagation of attached fungi is prevented. It is not only extremely hygienic, but also has deodorant and antibacterial properties that have excellent features such as active oxygen generated from water molecules instantaneously exerts an oxidative decomposition action and disappears because it is extremely safe to use. It can be said to be a granular substrate.
