BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a raw material for papermaking or a synthetic resin film, which is then mixed with a wrapping paper or a sack formed of the material, or an odor of an object to be packed which is stored in a paper container or container. The present invention relates to a deodorant antibacterial powder material capable of removing and antibacterial.

2. Description of the Related Art When processed foods including fresh foods are to be consumed, they are wrapped in a wrapping paper, a wrapping film or a wrapping bag, or stored in a paper container or a synthetic resin container. By the way, these wrapping papers, paper containers and the like are formed from a paper material, and the wrapping film, the synthetic resin container and the like are mainly made of polyvinylidene chloride, polystyrene, polyvinyl chloride, polyethylene material and the like.

However, wrapping paper, wrapping bags or paper containers made of paper materials are inexpensive and lightweight, and have water absorbency and air permeability. Many types have a peculiar odor, and this odor is permeated and diffused directly from the paper material or adsorbed together with the drip and leached and diffused to the outer surface, especially when brought into the vehicle such as transportation. As a result of filling and causing discomfort, furthermore, various fungi adhere or fall in during packaging and storage,
There is a danger that these will propagate in a short time and cause deterioration and freshness of the whole foods including freshness of fresh foods.

[0004] On the other hand, packaging films, packaging bags or packaging containers made of synthetic resin materials have no air permeability or water absorption and can suppress the diffusion of odors. The decrease in freshness is remarkable, such as atrophy or browning, and fungi that adhere or fall in during packaging or storage propagate and cause deterioration or decay in a short time. As a so-called antibacterial means for preventing the proliferation of such fungi, although food additives which are chemical agents having bactericidal or fungicidal properties against bacteria and fungi have been used exclusively,
In recent years, consumers have been repelled by concerns about safety due to the growing health consciousness.Also, although activated carbon is applied to one side of the packaging film as a deodorizing means, activated carbon has been tried. With only odor, the adsorbability is remarkably reduced as the odor is adsorbed, so that the diffusion of the odor cannot be prevented unless an extremely large amount of activated carbon is used.

[0005] The inventors of the present invention have conducted intensive studies in view of the above-mentioned problems, and as a result, have found that the wavelength of water molecules such as water contained in foods or water contained in foods or fungal cells is 2
Effective emission of near-infrared rays of 5 to 3 and 2 μm and far-infrared rays of wavelengths of 5, 0 to 7, and 4 μm creates active oxygen with high reactivity and oxidative decomposition power due to resonance excitation of water molecules. And that the odor molecules are oxidized and decomposed by the active oxygen to eliminate the odor, and even in fungi, the active oxygen also inhibits the inhibition and propagation of physiological functions. Is used together with the physical adsorption of odor molecules, and the deodorizing effect is remarkably exhibited.
The inventors of the present invention have found out that fine powder having a particle size of not more than μm can be easily dispersed in a paper material or a synthetic resin material and maintain workability.

[0006]

That is, the present invention can easily disperse and blend into a raw material for papermaking or a synthetic resin material, and has a deodorant property on a wrapping paper, a wrapping bag or a paper container, or a wrapping film or a packaging container. It is an object of the present invention to provide a deodorant antibacterial powder material capable of retaining antibacterial properties and eliminating odors from foods and preventing the propagation of fungi adhering thereto.

[0007]

The technical means adopted by the present invention to solve the above-mentioned problems is to effectively excite water molecules by resonance to obtain singlet oxygen, superoxide, hydroxy radical or hydrogen peroxide. In order to create active oxygen, near-infrared electromagnetic waves having an emission wavelength of 2, 7 to 3, or 2 μm and far-infrared electromagnetic waves having an emission wavelength of 5, 0 to 7, or 4 μm have at least 0 to the emissivity of the black body. ,
An electromagnetic radiation ceramic powder which can radiate with an emissivity of 8 or more and has a particle size of 1 μm or less, and a porous and electromagnetic radiation ceramic powder which can adsorb a large amount of odor molecules. It is made of activated carbon, diatomaceous earth or hydrated aluminosilicate mineral, which has the viscosity and plasticity that can be formed into a fine powder having a desired particle size. Is contained in a deodorant antibacterial powder material having a composition obtained by mixing 0, 3 to 3, and 0% by weight and baking and solidifying to a maximum particle size of 10 μm or less.

[0008]

The present invention having the above configuration has the following operation. That is, the adsorption binding powder material is made of a material selected from activated carbon, diatomaceous earth, or hydrous aluminosilicate mineral,
However, since substantially fine particles having a particle size of 3 μm or less are used, sufficient tackiness is created by adding an appropriate amount of water, so that 0, 3
To 3.0% by weight of the electromagnetic radiation ceramic powder material is kneaded while being strongly bonded, and plasticity is also created. This is sprayed in a high temperature heating atmosphere to form a required particle size. By calcining, the present invention is formed in which the adsorption bonding powder material and the electromagnetic wave radiation ceramic powder material are calcined and solidified together with the evaporation of water. In addition, since the adsorption bonding powder material is not only porous in nature, but also has a large amount of pores formed due to the evaporation of water during firing, the adsorption area of the odor is remarkably increased. In addition, since the present invention is made of an inorganic material and has a maximum particle size of 10 μm or less, it can be easily dispersed and compounded with a paper material or a synthetic resin material, and can be used for processing thin materials such as wrapping paper and wrapping film. Not only becomes possible, but also by using an appropriate adhesive, it becomes possible to apply firmly to the outer surface of a wrapping paper, a wrapping film, a paper container or a container.

According to the present invention which is compounded or coated on a wrapping paper, a wrapping film, a wrapping bag, a paper container or a container, the near-infrared electromagnetic wave having a radiation wavelength of 2, 7 to 3, or 2 μm and the radiation wavelength can be reduced. 5,0 to 7,4 μm far-infrared electromagnetic waves are radiated with high emissivity, so that moisture contained in foods, intracellular moisture of attached fungi, or moisture in air near these packaging materials Active oxygen is created by the resonance excitation of water molecules such as water, and the odor generated from foods is also adsorbed by the adsorptive binding powder with a large adsorption area, and the adsorbed odor molecules are instantaneously absorbed by the active oxygen. Decomposed and erased.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an explanatory view of an adsorption-bonding powder material 1 constituting the present invention. Since a material having a large adsorption area capable of adsorbing odor molecules of odors generated from odor sources such as foods to be adsorbed is required, a material having a porous structure is preferable, and the adsorbed binding powder is preferable. Since the material 1 is formed by mixing and kneading with the electromagnetic radiation ceramic powder 2 to form a powder having a required particle size, it is combined with the electromagnetic radiation ceramic powder 2 by a simple means, that is, by adding an appropriate amount of water. It is desired to have a viscosity for achieving the desired viscosity and a plasticity for forming a powder having a required particle size.

On the other hand, in the present invention, the maximum particle size is formed to be 10 μm or less so that it can be formed by mixing and dispersing it in a thin-walled product such as a wrapping paper or a wrapping film. The substantial particle size of the bonding powder material 1 is generally about 1/2 to 1/1 of the formed particle size.
Since the particles having a particle size of 3 or less are used, the particle size of the adsorptive binding powder material 1 is approximately 3 to 5 μm or less. As a result, the material requirements of the adsorptive binding powder material are those having a porous structure and viscosity and plasticity due to the addition of water, and specific materials satisfying such requirements include activated carbon and diatomaceous earth. Is selected.

Further, as a material which can be used for the adsorptive binding powder material 1 of the present invention, minerals composed of hydrous aluminosilicate generally called clay can be mentioned. That is, the minerals made of hydrous aluminosilicate have a fine interlayer structure inside, and contain water molecules in this interlayer structure, and the minerals made of hydrous aluminosilicate have viscosity and plasticity due to the addition of water. It is known to have In the present invention, when the mixture is kneaded with the electromagnetic wave radiating ceramic powder material 2 and formed into a required particle size after mixing and kneading, sintering and solidification are achieved, and heat sintering during the sintering and solidification reduces evaporation of water molecules in the interlayer structure. This is because a large number of pores are formed due to the accompanying porosity and evaporation of water added for imparting viscosity and plasticity. The particle size of the adsorption-bonding powder material 1 is specifically determined by the particle size of the present invention to be formed, but is generally about 1/2 of the formed particle size.
In order to form a material with the closest packing density, it is necessary to further reduce the particle size to 1/1.
It is desired that the adsorbent binding powder 1 has a particle size distribution in the range of 0 to 1/15.

The adsorbing bonding powder 1 is mixed with the electromagnetic radiation ceramic powder 2 in the range of 0, 3 to 3, and 0% by weight based on the weight of the adsorbing bonding powder 1.
The electromagnetic wave radiating ceramic powder material 2 emits an electromagnetic wave in the near infrared region having a radiation wavelength of 2, 7 to 3, or 2 μm and an electromagnetic wave in the far infrared region having a radiation wavelength of 5, 0 to 7, 4 μm in a black body. What has the radiation characteristic which can radiate | emit with emissivity of at least 0,8 or more with respect to an emissivity is used.

That is, in the present invention, the odor molecules generated from the odor generating source are diffused and mixed, and the moisture in the air, the moisture contained in the food itself, the intracellular moisture of the fungi adhering to, or the propagation environment Effective resonance excitation of water molecules in water to create active oxygen such as singlet oxygen, superoxide, hydroxyl radical or hydrogen peroxide, which has high reactivity and decomposes and eliminates odor molecules and fungi by oxidative decomposition power The purpose of the present invention is to achieve antibacterial activities such as inhibiting physiological functions and preventing reproduction.

The radiated electromagnetic wave energy radiated from the ceramic material 2 for radiating electromagnetic waves is extremely weak because it is a re-emission of the external temperature energy absorbed by the ceramic material 2 for radiating electromagnetic waves. Therefore, in order to effectively resonate and excite water molecules, electromagnetic waves in the near-infrared region of 2,7 to 3,2 μm and the far-infrared region of 5,0 to 7,4 μm, which are the resonance wavelengths of water molecules, can be emitted. It is also required that the emissivity of the black body is at least 0, 8 or more with respect to the emissivity of the black body.

The electromagnetic wave radiating ceramic powder material 2 emits electromagnetic waves in the near infrared region having wavelengths of 2, 7 to 3, and 2 μm and in the far infrared region having wavelengths of 5, 0 to 7, and 4 μm with respect to the emissivity of a black body. There is no particular limitation as long as it can emit at an emissivity of at least 0, 8 or more, but when used as a packaging material for foods, etc., heavy metals are restricted due to their composition, or heavy metals are used. Even if it is used, a material which has been subjected to a baking treatment so as not to elute at the time of use should be adopted.

The electromagnetic radiation ceramic powder 2 used in the present invention is as shown in FIG. 2. The specific composition of the ceramic powder 2 is 30 to 60% by weight of silicon oxide 2A and 20 to 40% by weight of aluminum oxide 2B. The weight ratio is a main component, and 2 to 3 kinds of transition element oxides 2C selected from manganese oxide, iron oxide, cobalt oxide, nickel oxide and titanium oxide as the transition element oxides 2C are 7 to 15% by weight. Further, as a catalyst for accelerating an electron transfer reaction for re-emission of electromagnetic waves, a catalyst prepared by calcining zinc oxide 2D in a proportion of 5 to 10% by weight is used. In addition, it is important for the electromagnetic wave radiating ceramic powder 2 that the present invention has a maximum particle size of 10 μm or less and that the electromagnetic wave radiating from the electromagnetic wave radiating ceramic powder 2 is radiated from the surface thereof. Therefore, in order to radiate the light more efficiently, a material having a large emission surface area ratio is suitable. For example, a material having a maximum particle size of 1 μm or less is used.

The adsorption bonding powder 1 and the electromagnetic wave radiation ceramic powder 2 thus formed are bonded to each other by their viscosity to form a deodorant antibacterial powder 3 of the present invention having a required particle size after kneading. Approximately 30 for the weight of powder material 1
~ 70% by weight of water is added. That is, the ratio of the water to be added depends on the means for forming the deodorant and antibacterial powder material 3 of the present invention.
When the means for spraying the electromagnetic wave radiating ceramic powder material 2 into a high-temperature heating atmosphere and baking and solidifying the powder into a particle having a particle size of 10 μm or less is employed, it is necessary to maintain the viscosity at such a low level that the powder can be sprayed. Approximately 50 to 70% by weight is added, and on the other hand, a molded product having an appropriate shape and size is formed from the kneaded adsorption bonding powder material 1 and the electromagnetic wave radiation ceramic powder material 2 by firing and solidifying once. In the case of a means for crushing the powder to a particle size by crushing it to a particle size of 10 μm or less by a crushing machine such as a ball mill or the like, since it can be formed with a relatively high viscosity, the amount of water to be added is about 30 to 50%. Becomes

In the case where the present invention is formed by firing and solidifying into a granular form by spraying, or when the present invention is formed by crushing after firing and solidifying a molded product having a required shape and size, The sintering temperature is determined by the water molecules in the interlayer structure of the mineral made of hydrous aluminosilicate or the adsorbed binding powder 1
Water added to impart viscosity and plasticity to water is evaporated in a short period of time so that porous or numerous pores can be formed, and furthermore, the porous structure of the material itself, such as zeolite, which has a porous structure, is damaged by heating. In order to avoid this, it is desired that the sintering be performed at a sintering temperature of about 150 to 300 ° C. for solidification. Needless to say, the firing time is appropriately determined by the ratio of water added for imparting viscosity and plasticity, and the particle size, shape, size, and the like formed by firing and solidification.

The deodorant and antibacterial powder material 3 of the present invention, which is formed by baking and solidifying into a powder or granules as described above, or by baking and solidifying as a molded product having a required shape and size and crushing into a powder or granules, as shown in FIG. A large number of fine pores 3A are formed with the required particle size and over the entire outer surface. The deodorant antibacterial powder material 3 of the present invention has a particle size of at most 10 μm.
Since the following fine particles are made of an inorganic material, they can be easily mixed and dispersed with a raw material for papermaking or a synthetic resin material.

The results of the deodorant test and the antibacterial test on the synthetic resin film prepared using the deodorant antibacterial powder material 3 of the present invention will be described below.

It was used. In the deodorization test, a test bag having a volume of 300 cc was formed from this film, and a similar bag was formed from a film prepared without blending the deodorant antibacterial powder material 3 of the present invention.
