    STERILIZING AND DEODORIZING AGENTS, THEIR METHOD
    MANUFACTURING AND USES, AND STERILIZATION METHOD
    The present invention relates to agents which are designed to continuously exert excellent sterilization and deodorant effects, etc., for a long time by being adhered to the surfaces of substrates such as paper, textiles, plastics, metals, ceramics and composite products.
    In the prior art, there are sterilization and deodorizing agents. However, these agents are either in solid form or in liquid form. Solid agents are related technologies, but use the oxidation-reduction capacity of a photocatalyst. While the photocatalyst can work for long periods of time, they can only work in the presence of UV light and do not work in the dark. Liquid agents, such as alcohol and chlorine-based agents, normally do not require light, but only work for short periods and evaporate and / or deteriorate quickly. More generally, many of the liquid sterilizers are toxic and therefore have the disadvantage of damaging the environment.
    While these photocatalysts have sterilization and deodorization effects in which bacteria, viruses, allergens and various odor-causing organic materials are broken down by radicals, they are produced by the oxidation-reduction reaction occurring on the surfaces of photocatalysts or photocatalysts in the presence of UV light. However, since the oxidation-reduction reaction only occurs at the photocatalyst interface and the reaction is very weak under visible light, photocatalysts are considered problematic in that they are not useful in dark environments.
    To make these photocatalysts useful, attempts, such as increasing the photocatalyst content or selecting the right crystal structure, have been made to solve the above problem. However, the aforementioned decomposition using the oxidation-reduction reaction does not have the ability to choose what is to be decomposed and what is not to be decomposed; in other words, all organic matter that exists near the photocatalyst is broken down. As a result, photocatalysts present another problem in that a substrate with photocatalysts and organic matter with photocatalysts disintegrate when the oxidation-reduction reaction is too strong.
    In addition, agents of the prior art also have the disadvantage of damaging the environment.
    Accordingly, an objective of the present invention is to overcome the problems of the prior art described above.
    A particular object of the present invention is to provide an agent which does not require light to function and persists for long periods of time.
    Yet another object of the present invention is to provide an agent having a sterilization effect superior to the metal compounds which exist in the prior art.
    Yet another object of the present invention is to provide an agent which is useful with a plurality of substrates and vectors.
    Yet another object of the present invention is to provide an agent which is easy and inexpensive to manufacture and use.
    The aforementioned features and objects of the present invention are accomplished by a combination of a metal-containing ceramic using (1) thermal bonding, (2) pressure bonding or (3) thermal / pressure bonding bonded to that -this. The ceramic is in the form of a particle and is chosen from the group consisting of TiO 2 , Cr 2 O 3 , Co 3 O 4 , AI 2 O 3 , SiC, CdS, CdSe, WO 3 , Fe 2 O 3 , SrTiO 2 and KNbO 3 and their mixtures, preferably titanium dioxide, and the metal is in the form of a particle and is chosen from the group consisting of gold, silver, platinum or copper powder or any combination of these, preferably money.
    The metal is bonded to the ceramic by thermal bonding, pressure bonding and thermal / pressure bonding.
    The finished agent can be mixed with paint, inks, adhesive, gels, coating agents and / or alone and printed, painted, sprayed and inserted into or intermingled on or with a variety of different substrates such as than paper, textiles, plastics, metals, ceramics and composite products. Likewise, the agent can be mixed with a variety of carriers such as lotions, creams, gels, ointments, water and other liquids or semi-liquids which can be applied to the human body and / or other surfaces.
    The agents of the present invention do not become effective when dissolved from the substrate in water. On the contrary, the agent of the present invention becomes effective by remaining on the substrate to maintain the decomposition of organic matter, and therefore the effectiveness lasts a long time and has no undesirable effects on the environment.

    The present invention includes a metal which is thermally bonded, pressure bonded, thermally / pressure bonded to a ceramic. The ceramic is chosen from TiO 2 , Cr 2 O 3 , Co 3 O 4 , AI 2 O 3 , SiC, CdS, CdSe, WO 3 , Fe 2 O 3 , SrTiO 3 and KNbO 3 , etc., but preferably TiO 2 because it is chemically stable, approved as a food additive, not associated with health problems, and readily available and inexpensive. In order to ensure a larger surface area and good workability for adhesion, the particle size of the ceramic is 0.3 to 100 µm, and is preferably 0.3 to 50 µm.
    The metal used in the agents currently invented constitutes a metal chosen from: gold, silver, platinum, copper, their combinations and various other metal particles, preferably silver. From an economic point of view, however, a combination of TiO 2 and silver is preferred because it has the above-mentioned characteristics and is non-toxic and is therefore harmless and does not influence the ecological system. In view of the relationship between the metal and the ceramic, the particle size of the metal is preferably 0.3 to 50 µm. In order for the agent to be effective in sterilizing bacteria, eliminating odors, etc., the weight ratio between ceramic and metal is preferably 100: 0.01 to 30, and 100: 0.05 to 15 in particular. The size of the agent comprising the metal bonded to the ceramic is 0.3 to 100 µm. The present agent can also be produced by mixing the ceramic to which the metal is bonded with adsorptive materials.
    An adsorptive material such as zeolite, sepiolite, apatite, activated carbon, etc. can also be used in the agent currently invented to adsorb and retain not only bacteria, viruses, allergens, fungi but also other target objects such as foul smelling substances and toxic substances, etc. The present invention uses in particular hydroxyapatite which functions as an adsorptive material. The particle size of the hydroxyapatite of the present invention is preferably 0.3 to 50 µm in particular, to provide larger areas and to achieve good workability. The weight ratio of the mixture of the ceramic to which the metal is bonded and the hydroxyapatite (i.e., the adsorptive material) is preferably 100: 1 to 50, and 100: 1 to 30 in particular, for desired effects of sterilization, deodorization, etc.
    The present agent can be produced by mixing the ceramic to which the metal is bonded with hydroxyapatite, i.e., the adsorptive material.
    The ceramic to which the metal is bonded can be manufactured by (1) thermal bonding in Figure 1, (2) pressure bonding in Figure 2 or (3) thermal / pressure bonding as shown in Figure 3.
    In this process, the ceramic (TiO 2 ) and metal (silver) particles are linked via a high temperature zone as shown in Figure 1. In the process, part of the metal is embedded in the ceramic particles. The instant temperature of the hot temperature zone is approximately approximately 2900 degrees Celsius. In this process, the ceramic and the metal are linked by the use of a ball mill, as shown in Figure 2. The ball mill contains very hard balls made of materials such as alumina or zirconium and which are approximately 0.1 mm and 0.004 mg. In addition, as shown in Figure 3, ceramic and metal particles can be bonded by applying heat and pressure simultaneously. Silver is 80-99.9% pure and titanium dioxide is approximately 90-99% pure. The resulting ceramic, the titanium dioxide to which thermally / pressure-bonded silver will be as substantially shown in Figure 4, and Figure 5 shows SEM (scanning electron microscope) images which describe the conversion of titanium dioxide and money in the form of film in the form of cartographic images.
    While the above process for bonding metal to ceramic is described above, other processes such as high temperature rollers and high temperature ultrasonic bonding may be used.
    The agent of the present invention can be adhered to target objects such as wood, fabric, plastic, metal, ceramic, concrete, etc., by coating, etc. to be used, and it can also be used as an interior filler. While the agents of the present invention are useful as such, they can also become useful materials by being dispersed in dispersing agents, such as water, organic solvents, adhesives, etc. The agents of the present invention can be adhered to the target objects by coating, etc. to be used, and they can also be contained as an interior material.
    In addition to the foregoing forms, the present invention may take the form of printing ink and paint materials. These forms also aim to impart sterilization and deodorization and decorative effects. Printing ink, another form of the present invention, not only contains the ceramic to which the metal is bonded, and hydroxyapatite as an adsorptive material but also contains at least colored and vector materials. The printing ink also contains other ingredients if necessary. As a colored material, not only inorganic pigments and organic pigments (i.e. colored materials commonly used for printing ink) but also dyes such as a solvent dye and a dispersion dye , etc. can be listed as an example. As vectors, we can list the following:
    an oil, for example a drying oil such as linseed oil, etc., a semi-drying oil such as soybean oil, etc., and a non-drying oil such as castor oil, etc. ; resins, for example a natural resin (such as rosin, modified rosin, gilsonite, etc.), a natural resin derivative, a phenol resin, an alkyd resin, a xylene resin, a d resin urea, melamine resin, poly (amide) resin, acrylic resin, epoxy resin, ketone resin, petroleum resin, poly (vinyl chloride) resin, poly (vinyl acetate) ), a urethane resin, chlorinated poly (propylene), a chlorinated rubber, a cyclized rubber, a cellulose derivative and a reactive resin; and a plasticizer.
    Similarly, like other materials, we can list the following:
    wax components in natural wax or synthetic wax, a drying agent, a dispersing agent, a wetting agent, a crosslinking agent, a gelling agent, a thickening agent, an anti-skinning agent, a stabilizer, an agent mat, a defoamer, an anti-flotation agent and an antifungal agent, etc.
    when there is no specific mixing ratio for these components, the mixing ratio found in common printing ink on the market is useful.
    So that the printing ink has the effect of sterilizing bacteria and eliminating odors, etc. and ensuring correct printability, the preferred total amount of the agent of the present invention comprising a ceramic to which a metal is bonded by pressure is 3 to 80% of the total weight of the printing ink, and 10 to 80% in particular.
    The forms or types of printing ink are not particularly limited. It can be compact ink, solvent ink, or solvent-free ink. They can also be used as an offset printing ink, an ink for lithographic printing, an ink for photogravure, an ink for screen printing, an ink for intaglio printing or an ink for special printing. To best achieve the object of the present invention, an ink for screen printing, for example, a screen printing ink for paper, a screen printing ink for plastic, a screen printing ink for glass, a screen printing ink for metals and a screen printing ink for fabric, etc., are preferred from the above types.
    In addition to the above, other forms of the present invention are explained below. Paint materials can not only contain the agent of the present invention comprising the ceramic particles to which the metal is bonded but can also contain at least film-forming components and dispersing agents. Other components can also be contained if necessary.
    As film-forming components, the following can be listed: synthetic resins such as cellulose derivatives, phthalate resin, phenol resin, alkyd resin, aminoalkyde resin, acrylic resin, epoxy resin, urethane resin, poly (vinyl chloride) resin, silicone resin, fluorocarbon resin, emulsion, water soluble resin, etc. ; and a vegetable drying oil.
    As dispersing agents, the following can be listed: a petroleum solvent, an aromatic solvent, an alcohol solvent, an ester solvent, a ketone solvent, a cellosolve solvent, water, etc. In addition, in the case of a powder paint, solvents as dispersing agents are not necessary.
    As other components, the following can be listed: pigments, for example inorganic pigments, such as titanium dioxide, lead chromate, Indian red, chromium oxide, carbon black, etc. organic pigments, such as Hansa yellow, novaperm orange, quinacridone violet, copper phthalocyanine, etc. ; body pigments, such as precipitated calcium carbonate, barium sulfate, talc, clay, white carbon, etc. ; special functional pigments represented by anticorrosive pigments, such as zinc chromate, strontium chromate, zinc phosphate, aluminum phosphate, etc.
    In addition, in addition to the foregoing, the following may be incorporated as additional materials: a drying agent and a polymerization catalyst to accelerate the drying of paint films; a wetting agent, a pigment dispersing agent, an anti-flotation agent and an anti-sediment agent to improve the dispersibility of pigments; a thickening agent, a thixotropic agent, an anti-sagging agent for regulating the fluidity of the pigments; and a flow agent, an antifoam agent, an antiretraction agent, an anti-float agent as well as a plasticizer, an anti-skin agent, an electrostatic coating aid, an anti-scratch agent, an anti-blocking agent, an anti-UV agent, an anti-fouling agent, an antiseptic agent, an anti-fungal agent, etc. to regulate painted surfaces. There is no special combination report for these components, and the report should appear to those skilled in the art.
    The combination ratio found in common paint materials on the market is helpful. In order for the paint material to exert bacteria sterilization and odor removal effects, etc., and to ensure proper paintability, the preferred total amount of the agent of the present invention comprising ceramic particles to which a metal is bonded is 3 to 80% of the total weight of the paint material, and 10 to 80% in particular.
    Coating methods for paint materials are not particularly limited. Methods such as brush coating, pneumatic spray coating, airless spray coating, electrostatic spray coating, powder coating, electroplating coating, curtain spray coating, roller coating brushes, etc. can be used.
    The area required for presently invented agents is not particularly limited. It depends on the use of agents.
    The agent of the present invention can be used by mixing with a liquid solution or an agent which can be used on the human body and / or other surfaces representing a shape such as an ointment, a skin lotion, etc. ., and become effective in sterilizing bacteria and eliminating odors, etc. For example, mixing with a liquid solution or agent is useful for a variety of products such as cosmetics, hand cream 11 in Figure 6, ointment, ointment for medical treatment (for diseases which are associated to the skin, to the epidermis such as tinea pedis, a burn (scald), bedsores (decubitus), secondary disease of atopic dermatitis, wounds, etc.
    In addition, the agent of the present invention can be used not only by mixing with a liquid solution or an agent but also by mixing with products such as resin, ceramics, adhesive, etc. and mixing with raw materials which are intended to prepare materials.
    As represented by the forms of printing ink, paint materials, etc., the presently invented agents can be bonded in various forms to paper, wood, fabric, plastic, metal, concrete. , etc. and become effective in sterilizing bacteria and eliminating odors, etc. Also, the agents of the present invention can exert decorative effects by being printed in desired patterns or graphics and can be used for a variety of decorations and other purposes for which light irradiation is considered unavailable. For example, by being adhered to ceramics, a metal, composite products, the agents of the present invention are useful for a variety of products such as drinking water (Figure 7), preserving drinking water 12 in FIG. 6, the storage of rainwater (FIG. 8), the reuse of rainwater, a reservoir, a pond, the washing and cleaning of vegetables, aquaculture (hydroponics), a cooling tower (figure 9), a bathtub, a thermal spring, soil improvement (figure 10), the conservation of foodstuffs, the maintenance of the freshness of food products, a drainage ditch, a paving stone 13 on Figure 6, a humidifier 14 in Figure 6, medical equipment, column packing, etc., and by being adhered to paper, the presently invented agents are useful as living materials, such as various papers packaging, bags, etc. for storing food, filters, medical materials, medical products, and materials, products as living materials such as wallpaper 15 in Figure 6, shoji paper, fusuma paper, materials of external surface for furniture 16 in FIG. 6, etc. Furthermore, by being adhered to resin, the agents of the present invention are useful for various types of films such as decorative film, protective film, food packaging film, for resin products in the medical sector such as a catheter, an endoscope, a balloon, an instrument button, for products such as a personal computer 30 in FIG. 6, as a telephone 17 in FIG. 6, as dryers air knife hands 18 in FIG. 6, as play equipment, etc., for housing materials such as handrails 19 in FIG. 6, roofing materials 28 in FIG. 6, etc. as well as materials needed to make these products. They are also useful as glues which are contained in the raw materials of paper, woven and / or nonwoven.
    ίο
    By being adhered to a fabric (textile materials) and a woolen fabric, the presently invented agents are useful for various products such as fabrics 21 in Figure 6, materials for foodstuffs, materials for use in agriculture , materials for medical use, adhesive plasters (adhesive bandages) 22 in Figure 6, gauze, bandages such as white bandages, gowns 23 in Figure 6, uniforms, face masks 24 in Figure 6, curtains 25 in Figure 6, bedding (sheets), futon tops, blankets, pillowcases, etc., various covers (seat covers, floor cushion covers, etc.) , tablecloths, rugs 26 in FIG. 6, napkins, handkerchiefs, etc., as well as for materials necessary for manufacturing these products. They can also be used as materials for air purification filters 27 in Figure 6, water purification filters 29 in Figure 6, etc. In addition, they can be used to paint buildings and other structures, paint various products, and add soil-resistant paint to boats, bridges, docks, etc. to repel aquatic animals such as coronule, serpule, mussel, etc. They can be used to prevent algae from starting.
    The presently invented agents, first, adsorb bacteria, viruses, fungi, as well as bad smelling substances, toxic substances, etc. After their adsorption or at the same time as their adsorption, bacteria and viruses, fungi, etc. decompose. In addition, the effect of the present invention stops the growth of or repels anything that is not broken down. Likewise, without light irradiation, the agents currently invented have the same effects as under light irradiation at normal temperature for humans living on Earth. In addition, because the proteins constituting bacteria, viruses, fungi, etc. decompose and disappear, the above-mentioned effects do not diminish over time but last semi-permanently.
    Bacteria, fungi, etc. prefer conditions of high temperature and high humidity to multiply. The agent of the present invention is effective in particular under conditions of high temperature and high humidity and is therefore effective against bacteria and fungi.
    As a result, since the sterilizing components in the presently invented agents are insoluble, the agents represent a technology very widely useful for killing and suppressing the growth of undesirable living organisms such as bacteria, fungi, etc. In places where public hygiene, bacteria control, odor control, etc. are required such as houses, hospitals, retirement homes, public institutes, food factories, hydraulic stations, etc., since it is difficult to handle a product, the products for which the agents of the present invention are used are extremely effective for their use as a "system" by freely combining them on demand, and become effective in sterilizing bacteria and eliminating odors, etc. For example, a "system" that aims to control infection is shown in Figure 6.
    Furthermore, in order to acquire an additional effect in wider fields, by using both a medicament as it exists and the products or systems for which the agents of the present invention are used, they can be used as new sterilization system (sterilization process) which contains rapid efficiency and continuity (see Figure 11).

    In addition to this, the present invention does not constitute a burden on the environment.
    There are a variety of medical products used to sterilize bacteria, deactivate viruses, break down allergens, and deodorize. However, these medical products must contend with the fact that the more effective they are, the more inherently destructive they are to the human body and the natural world. However, the agents of the present invention do not influence the environment, since the agents do not dissolve in water and last a long time and are effective for long periods.
    It is apparent that the described embodiments are few but can be implemented by those skilled in the art without departing from the spirit and scope of the present invention.
    Of course, the invention is not limited to the examples of embodiment described and shown above, from which other modes and other embodiments can be provided, without going beyond the ambit of the invention.
