DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorant ceramic powder which prevents generation of odor by radiated electromagnetic waves of ceramics and eliminates odor generated by the generated odor.

[0002]

2. Description of the Related Art In recent years, there has been a growing interest in environmental hygiene in accordance with the improvement in living standards, and so-called deodorization and deodorization have been taken up as a major issue for measures against odors in living spaces as well as in spaces such as stores and public facilities. It is being done. Conventionally used as a means of deodorizing or deodorizing include a method of masking an odor with an aromatic substance stronger than the odor, a chemical method of deodorizing by chemically changing with fluorine or ozone gas, an odor molecule. A physical method of deodorizing by adsorbing odor molecules on a porous substance, and a biochemical method of deodorizing by decomposing odor molecules with an enzyme generated by a microorganism.

However, in the masking method,
Because the smell of the aromatic substance used as masking is disliked or disliked, its use range is severely restricted, and furthermore, the chemical method can be used for deodorizing the whole living space, shops, public facilities, etc. in terms of safety. Rather, it is limited to the use of certain products at the production stage or in special closed systems,
In addition, in the physical method, the adsorbent must be replaced after a certain amount of adsorption is performed, and in the biochemical method, not only is the effect short-lived, but also the specific odor is decentralized. There is a problem that the odor which has high selectivity and is produced in a complex manner cannot obtain an effective deodorizing effect.

In view of such circumstances, the inventors have conducted intensive studies on the mechanism of generation and deodorization of odors. Hydrogen sulfide and other mercurtans, aldehydes, indole and skatole and other odor components are generated together with the growth while decomposing fat, and the deodorization is to suppress or prevent the growth of the spoilage fungi. It has also been found that the generated odor can be deodorized by oxidizing and decomposing the odor component to another component.

[0005] Furthermore, the inventor of the present invention requires not only nutrients and oxygen but also a temperature suitable for growth and water suitable for physiological functions in a growing environment in addition to nutrients and oxygen in order to grow putrefactive bacteria. The main component of the microbial cell is water, which has a resonance wavelength band for electromagnetic waves having a wavelength of 1 to 3 μm and an electromagnetic wave of 6 to 11 μm because of its molecular structure. Water molecules are resonated and excited by the electromagnetic wave radiation in the wavelength region to remarkably denature and inhibit the physiological function of spoilage fungi, or the growth of the water molecules becomes unsuitable for environmental water, and the growth of water molecules is suppressed. Hydroxyl radicals with high reactivity and strong oxidizing power are generated with resonance and excitation, and in the presence of a metal compound, the metal compound acts as a catalytic action to further enhance the oxidation reaction. In the presence of silver and copper, the present invention has also been studied for a variety of fungi constituting the spoilage bacterium, and it has been found that a more reliable bactericidal action, a so-called oligodynamic action, is exhibited, and the like, and the present invention has been accomplished. .

[0006]

That is, the present invention resonates and excites water molecules of water forming environmental cells and essential moisture for the growth of spoilage fungi and inhibits the physiological functions of spoilage fungi by denaturation of water. To provide a deodorant ceramic powder which can prevent the generation of odor by suppressing the growth of odors, and decompose the odor generated by the strong oxidizing power of the generated hydroxy radicals to deodorize safely and for a long period of time. Is to do.

[0007]

The technical means used by the present invention to solve the above-mentioned problems is that of silicon oxides 40 to 6
One or two types of metal oxides selected from iron oxide, nickel oxide, titanium oxide, zinc oxide or lead oxide are used in an amount of 30 to 45% by weight of alumina oxide to 0% by weight.
When the composition is fired at a composition of about 14% by weight, the emission wavelength of the ceramics can be 1 to 3 μm and 6 to 11 μm, which can resonate and excite water molecules. In order to enhance the resonance and excitation of water molecules and to disperse and mix them in various materials to achieve uniform electromagnetic wave radiation, a ceramic powder having a particle size of 1 μm or less is obtained. Silver or copper having a dynamic action is added to the substrate.
The present invention resides in the configuration of a deodorant ceramic powder which is supported at a weight ratio of 1 to 1.0%.

[0008]

The technical means of the present invention has the following functions. That is, the composition of the ceramic is 40 to 60% by weight of silicon oxide, 30 to 45% by weight of alumina oxide, and one or two kinds of metal oxides selected from iron oxide, nickel oxide, titanium oxide, zinc oxide and lead oxide. Is 7 to 1
4% by weight and 37-59% of various metal oxides
By being used in a large proportion by weight, the radiation wavelength is expanded from a far-infrared electromagnetic wave region of approximately 6 μm or more, which is a general radiation wavelength of ceramics, to a near-infrared region of approximately 1 μm, thereby forming bacteria of spoilage fungi. Water molecules of water and environmental water which is essential for growth are resonated and excited to become denatured water which is unsuitable for maintaining physiological functions and growing, and hydroxyl radicals having high reactivity and strong oxidizing power are generated by the excitation. Decomposes odor components. Since the deodorized ceramic powder is formed into fine particles having a particle size of 1 μm or less, the surface area ratio is large, the radiation of electromagnetic waves is efficiently radiated, and silver or copper is carried, so that the presence of environmental moisture is present. Underneath, the oligodynamic action associated with ionization acts to prevent growth throughout the spoilage fungi.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an enlarged explanatory view of the present invention. FIG. 1 is an enlarged view of the present invention. In addition, the water molecules of the water forming the spoilage fungi and the environmental water essential for the growth are resonated and excited, thereby inhibiting the physiological function of the spoilage fungi and inhibiting the growth due to the denaturation of water. A radiator having a wavelength of 1 to 3 μm and a wavelength of 6 to 11 μm, which are the resonance wavelength ranges of water, because it is intended to eliminate the odor generated by generating hydroxyl radicals having high reactivity and strong oxidizing power. Is requested.

[0010] By the way, ceramics have long been known to have excellent electromagnetic wave radiation characteristics. However, the use of radiated electromagnetic waves of ceramics has been conventionally used in order to improve the industrial drying property by utilizing the permeability of heat rays. Or, since the main purpose was to transmit heat rays to the inside of the body to promote blood circulation, the radiation electromagnetic wave area was mainly in the so-called far-infrared region having a wavelength of about 6 μm or more, which is excellent in heat ray transmission. Properties are required, and therefore, the main components of the ceramic composition are zirconia (ZrO ₂ ), titania (TiO ₂ ),
Alternatively, alumina (Al ₂ O ₃ ) was mainly used.

Thus, the present invention resonates and excites water molecules of the moisture forming the cells such as spoilage fungi and environmental moisture essential for growth, and emits near-infrared electromagnetic waves having a radiation wavelength of 1 to 3 μm and 6 μm. It is required that a far-infrared electromagnetic wave of about 11 μm be radiated efficiently with a high emissivity.

Therefore, silicon oxide 1A capable of emitting far-infrared electromagnetic waves at a high emissivity contains 40 to 60%
Use the weight and further increase the emission wavelength by 1 to 3μ.
In order to radiate a wide range of electromagnetic waves in the near-infrared region of m, 30 to 45% by weight of alumina oxide 1B and one or two kinds selected from iron oxide, nickel oxide, titanium oxide, zinc oxide or lead oxide The ceramic powder 1 is formed by firing the metal oxide 1C having a composition of 7 to 14% by weight.

In such a case, iron oxide, nickel oxide, titanium oxide, zinc oxide, or lead oxide is selected as the metal oxide 1C because the emission wavelength is 1 to 3 μm over a wide range of electromagnetic waves in the near infrared region. The metal oxide 1C acts as a catalyst during the emission and the oxidation reaction relating to the odor decomposition by the highly reactive and strong oxidizing hydroxyl radical generated by the resonance and excitation of the water molecules by the emitted electromagnetic waves. This is because the oxidation reaction is further promoted.

In addition, it is important that the electromagnetic radiation energy of the formed deodorizing ceramic powder 2 is weak because it is due to the temperature difference from the absolute temperature. In addition, in practical use, it is used by being mixed with a material such as synthetic resin, paper or cement, or mixed with a paint or various coating materials, etc. It needs to be formed into a so-called fine particle having a large surface area ratio, and the particle size is formed to be 1 μm or less at the maximum.

Further, the firing technique for forming the ceramic powder 1 does not require any special technique, and it can be formed using a general firing technique for ceramics. However, due to the formation of fine particles of 1 μm or less, ultrafine particles each having a particle size of 0.2 to 0.3 μm or less are used due to the fact that such ultrafine particles are mutually reciprocal. Since the bonding force acts strongly, firing at a temperature slightly lower than the firing temperature of general ceramics is advantageous in further increasing the surface area ratio.

The ceramic powder 1 thus formed is ionized by moisture in the growth environment to create an oligodynamic effect on various fungi constituting the spoilage fungi, thereby ensuring sterilization and preventing odor generation. Silver or copper 1D is supported at a weight ratio of 0.1 to 1.0%, so that the deodorant ceramic powder 2 of the present invention can be used.
Is formed.

The test results of the antibacterial and deodorant properties using the present invention are described below. The deodorant ceramic powder 2 of the present invention is mixed and dispersed in a polyethylene film grade resin by 0.1% by weight, and the thickness is 40 μm. A polyethylene film material of 20 cm wide and 30 cm long using the film material
The antibacterial deodorizing bag 3 as shown in FIG. Further, as a control, a polyethylene film having a thickness of 40 μm was formed using a polyethylene film grade resin, and an untreated bag formed of the same size was used.

In the antibacterial test, three strains of Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus were used. The test method was as follows.
After adjusting to 0 ^6-7 / ml, 2 ml of the test bacterial solution was dropped into a sterile petri dish, and a 2 cm × 2 cm size cut and collected from the antibacterial deodorizing bag 4 and the untreated bag was dropped on the test bacterial solution. Each sample was allowed to stand, and 0.1 ml of bacterial solution was added every time.
Table 1 shows the results obtained by taking out, smearing, reculturing, and reading the viable cell count.

[0019]

[Table 1]

Next, the method of the deodorization test is as follows: ammonia gas, methyl mercaptan gas adjusted to a predetermined concentration in advance,
Acetic acid gas, hydrogen sulfide gas, and isovaleric acid gas were sealed in the antibacterial deodorizing bag 4 and the untreated bag, respectively, and the residual concentration of each sealed gas was measured at each elapsed time. The results are shown in Table 2 using a gas detector tube.

According to the present invention, as described above, an electromagnetic wave that resonates and excites water molecules is radiated using the temperature difference from the absolute temperature as energy, so that the electromagnetic wave is radiated for a long period of time. As a result, the water molecules of the spoilage fungi that form the cells of the fungi and the environmental water that is essential for growth resonate and are excited, so that the physiological function of the fungi is inhibited and the fungi are denatured into water unsuitable for growth. And the growth is prevented to prevent the generation of odor. Furthermore, the presence of environmental moisture ionizes the silver or copper carried, and the various kinds of fungi constituting the spoilage fungi are sterilized by the oligodynamic action. In addition, odor generation can be prevented. Hydroxyl radicals having high reactivity and strong oxidizing power are generated along with resonance and excitation of water molecules, and the odor component generated in combination with the fact that the oxidation reaction is further promoted by the presence of the metal oxide is reduced. Oxidation and decomposition are surely achieved in a short time to achieve deodorization. Further, the present invention has a particle size of 1 μm.
Because it is formed into the following extremely fine particles, it can be well dispersed even when used with a material such as synthetic resin, paper or cement, or mixed with a paint or coating material. It is a deodorant ceramic powder that has an extremely large number of features, including the ability to expect a uniform deodorant effect from products.
