Description

  The present invention relates to an indoor antibacterial deodorizing method using a titanium phosphate compound having an antibacterial action and a deodorizing action, and a chemical solution suitable therefor.

Conventionally, fungi and germs that propagate in the room are sterilized, and malodorous components such as ammonia, acetaldehyde, hydrogen sulfide, methyl mercaptan, trimethylamine, and skatole are decomposed, and chemicals such as fungicides and acaricides. Various antibacterial deodorants are used to make indoor environment comfortable by decomposing formaldehyde, toluene, xylene, ethylbenzene, styrene, etc., which are released into the room from tatami mats, carpets and building materials treated with substances and cause sick house syndrome. A method has been developed.
As a conventional technique, (Patent Document 1) states that “the ozone water in which ozone is dissolved in water is sprayed on the space to be sterilized together with the air, so that ozone is continuously decomposed for a long period of time and the sterilizing effect of ozone is prolonged. Disclosed is a method for sterilization by ozone that is sustainable for a period of time.
(Patent Document 2) discloses “a spray agent for antibacterial, antifungal, deodorant, and soil decomposition containing 0.1 to 20% by weight of titanium dioxide having an average particle size of 0.2 μm or less”.
In addition, as a technique for deodorizing a room using a titanium phosphate compound having a catalytic action, (Patent Document 3) states that “an ornamental artificial plant having a deodorizing function whose surface is coated with titania phosphate”. Is disclosed.
JP-A-4-15060 JP-A-8-165215 JP 2003-247113 A

However, the above conventional techniques have the following problems.
(1) The technology disclosed in (Patent Document 1) shows that the sprayed ozone decomposes organic substances such as mold, germs, and chemical substances, and exhibits excellent antibacterial and deodorizing effects. And the deodorizing effect was not acquired and it had the subject of lacking in sustainability.
(2) Since the technology disclosed in (Patent Document 2) decomposes organic matter by utilizing the photocatalytic action of titanium dioxide and exhibits antibacterial and deodorizing effects, spraying a spray agent on the target object When a film is formed and the film is irradiated with light having energy higher than the band gap of titanium dioxide, the antibacterial and deodorizing effects can be expressed for a long time. However, in indoor spaces such as residences and hotels, and in dark warehouse rooms and transport vehicles with few windows, even if a titanium dioxide coating is formed on the walls and floors, it is sufficient because it is difficult to insert strong light into every corner of the room. A photocatalytic action could not be obtained, and there was a problem of lack of antibacterial and deodorant properties.
(3) In order to form a titanium dioxide film on the object, the spray agent is blended with a binder such as a silicone resin that binds the titanium dioxide particles to the object. This binder is the surface of the titanium dioxide particles. In other words, the catalyst performance is reduced.
(4) Since the binder that binds the titanium dioxide particles and the object is easily decomposed and deteriorated by the photocatalytic action of titanium dioxide, there is a problem that the coating is easily peeled off from the object.
(5) In the technique disclosed in (Patent Document 3), it is considered that active oxygen such as OH radicals are generated by contacting oxygen in the air with water and titania phosphate, which can be viewed even in the dark. Deodorizing action can be obtained by decomposing and removing odor components in the air in contact with artificial plants. However, since it does not form a titania phosphate film on all objects in the room, it has a problem that it cannot sterilize molds, germs and the like that propagate on the object. In addition, the deodorizing action can be obtained only in the vicinity where the ornamental artificial plant is placed, which is local, and has a problem that it takes a long time to deodorize the room.

SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and forms a uniform and strong titanium phosphate compound film on the surface of an indoor object without being affected by the season, weather, or the material of the object. It can reduce indoor floating bacteria and harmful bacteria, decompose odor, prevent mold and germs for a long time, prevent atopy, allergy, hay fever, asthma, pet odor and tobacco odor. Deodorant, reduction of mold caused by moisture and dew condensation, prevention of infection in medical facilities and educational facilities, prevention of tobacco dust adhesion, etc. can be sustained for a long period of time. An object of the present invention is to provide an indoor antibacterial deodorization method that is excellent in workability.

In order to solve the above-described conventional problems, the indoor antibacterial deodorizing method and chemical solution of the present invention have the following configurations.
In the indoor antibacterial deodorization method according to claim 1 of the present invention, a chemical solution in which a titanium phosphate solution containing a titanium phosphate compound or a condensate thereof as an active ingredient is mixed in a sealed room is mixed. It has the structure provided with the chemical | medical solution spraying process to spray.
With this configuration, the following effects can be obtained.
(1) Since a chemical solution in which a titanium phosphate solution and a diluent are mixed is sprayed in a sealed room, the mist-like titanium phosphate solution spreads to every corner of the room, and the walls, ceilings, A film can be formed on all objects such as floors, tatami mats, carpets, windows, furniture, etc., and the workability is excellent.
(2) Titanium phosphate compounds and their condensates can decompose harmful bacteria such as Escherichia coli, staphylococci and salmonella present in the living environment without affecting the human body, so kitchens, canteens, food factories Antibacterial and deodorant such as can be performed, the application range is wide and versatility is excellent.
(3) Since the diluent is mixed in the chemical solution, the chemical solution is increased even if the amount of the titanium phosphate solution applied is small, and the water-soluble titanium phosphate compound is reliably adhered to the target. It is possible to form a uniform and strong titanium phosphate compound coating on the surface of the object, and to maintain the antibacterial and deodorizing effects for a long period of time.

  Here, the room to which the present invention is applied includes a living room of a residence, a reception room, a washroom, a living space such as a kitchen, a toilet, and a bathroom, storage facilities and storage facilities such as a storage, a storage, a warehouse, and a cargo container, a hotel Guest rooms such as hotels and inns, lodging facilities such as lobbies, sauna facilities, bathing facilities such as changing rooms, locker rooms, offices, offices such as factories, medical facilities and welfare facilities such as hospitals, education for schools, kindergartens, nurseries, etc. Eating and drinking facilities such as facilities, canteens, restaurants, etc., moving spaces such as trains, buses, automobiles, airplanes, ships, cargo trains, etc. (inside cars, cabins, cargo compartments, etc.) are used.

As the titanium phosphate solution, a solution containing a titanium phosphate compound or a condensate thereof as an active ingredient is used.
The titanium phosphate-based compound has a general formula of Ti (OH) _x (PO ₄ ) _y (HPO ₄ ) _z (H ₂ PO ₄ ) _m (OR) _n (where R is an alkyl group having 1 to 4 carbon atoms, x is an integer of 0 to 4, y is 0 or 1, z is an integer of 0 to 2, m is an integer of 0 to 4, n is an integer of 0 to 4, and x + 3y + 2z + m + n = 4 is satisfied. For example, Ti (OH) (H ₂ PO ₄ ) ₂ (OR), Ti (OH) (PO ₄ ), Ti (OH) ₂ (H ₂ PO ₄ ) (OR), Ti (OH) (HPO ₄ ) (OR), Ti (OH) (HPO ₄ ), Ti (OH) ₂ (H ₂ PO ₄ ) ₂ , Ti (OH) ₃ (H ₂ PO ₄ ), Ti (OH) ₃ (OR) Etc. are used.
A titanium phosphate compound or a condensate thereof can be obtained, for example, by the following production method. That is, first, titanium tetrachloride is reacted with water or alcohol, or a mixed solution thereof. As alcohol, C1-C4 methanol, ethanol, isopropyl alcohol, etc. can be used. Next, a titanium phosphate compound can be obtained by reacting the obtained reaction solution with phosphoric acid. The obtained reaction product can be diluted with water, alcohol, or a mixed solvent of alcohol and water to obtain a titanium phosphate solution in a solution state or a dispersion state.

  A solution obtained by adding a sodium silicate compound, a titanium silicate compound, a titanium borate compound or the like to a titanium phosphate solution containing a titanium phosphate compound or a condensate thereof as an active ingredient can also be used. By adding these, it is possible to enhance the deodorizing action, prevent the solid matter from precipitating, and make it difficult to clog the nozzle of the sprayer.

  As the diluent, water such as tap water, purified water, ion exchange water, distilled water, electrolytic water, alcohol such as ethanol or isopropyl alcohol, or a mixed solution of alcohol and water is used. This is because the titanium phosphate compound and its condensate are soluble and have few germs. In particular, purified water, ion-exchanged water, distilled water, electrolytic water, etc. are preferably used as water. This is for preventing calcium and the like in the water from depositing on the nozzle of the sprayer and clogging.

  In addition to titanium phosphate compounds or polymers thereof, diluents, catechins, fragrances, preservatives, surfactants, and the like can be added to the chemical solution. Catechins can enhance antibacterial properties, fragrances can release fragrances indoors to enhance comfort, preservatives can enhance storage, and surfactants enhance wettability to objects. The emulsifiability of catechins and the like can be increased.

In the chemical spraying process, the titanium phosphate solution and the diluent are sprayed indoors by spraying a mixture of the titanium phosphate solution and the diluent using various sprayers, the titanium phosphate solution and the diluent. Various methods such as spraying separately can be used.
In addition, the mixing ratio of the titanium phosphate solution and the diluent can be appropriately selected in the range of 1: 0.5 to 1:20 depending on the room in which the chemical solution is sprayed.

  The room temperature for spraying the chemical solution is 5 to 50 ° C, preferably 20 to 40 ° C. As the indoor temperature drops below 20 ° C, the sprayed titanium phosphate solution is slow to dry, so dripping and the like tend to occur in the thickness and concentration of the coating, and the temperature rises above 40 ° C. As a result, the sprayed titanium phosphate solution dries quickly and it is difficult for the titanium phosphate compound to diffuse, and it tends to be difficult to form a film having a uniform thickness on the object in the room. In particular, when the temperature is lower than 5 ° C. or higher than 50 ° C., these tendencies become remarkable, so that neither is preferable.

  In the chemical spraying process, the windows are closed and the interior is sealed. This is to keep the room at high humidity during the work and prevent the chemical solution from being scattered outside the room and wasted. Moreover, it is preferable to perform it in the state which stopped the air conditioner. This is for preventing the generation of airflow in the room and spraying the diluent and the titanium phosphate liquid uniformly in the room.

  The spraying time in the chemical spraying process is about 5 to 25 minutes in the interior of an automobile. When antibacterial deodorizing treatment is performed in a large room such as a factory, the number of sprayers to be placed in the room and the spraying time can be appropriately selected in consideration of the flight distance of liquid particles according to the size of the room. it can.

  After the chemical solution is sprayed into the room, the interior of the object is dried to dry the surface of the object, and a titanium phosphate compound film is formed on the object, which is brought into contact with oxygen in the air and water. Active oxygen such as radicals is generated, and a deodorizing action is obtained by decomposing and removing odor components in the air in contact with the object even in a dark place. Furthermore, molds, germs, and the like that are in contact with the object can be sterilized.

Invention of Claim 2 of this invention is the indoor antibacterial deodorizing method of Claim 1, Comprising: In the said chemical | medical solution spraying process, the said titanium phosphate liquid and the said diluent are each sprayed and the said room | chamber interior It has a mixed configuration.
With this configuration, in addition to the operation obtained in the first aspect, the following operation can be obtained.
(1) If the titanium phosphate solution is diluted and allowed to stand, solids are likely to precipitate and turbidity is likely to occur, and the nozzles of the sprayer may be clogged with the precipitated solids, but each of the titanium phosphate solution and the diluent As it is sprayed and mixed in the room, the titanium phosphate solution can be kept above the non-precipitating concentration of the precipitated solid, and it is difficult for the solid to precipitate, and fine liquid particles can be sprayed without clogging the nozzle of the sprayer. Excellent.

Here, for spraying the chemical solution indoors, various sprayers that spray the titanium phosphate solution and the diluent separately can be used, but a vaporizer, a pump that pumps the diluent to the vaporizer, A two-fluid spray type sprayer including a first nozzle that communicates with the downstream side of the vaporizer and a second nozzle that is disposed near the first nozzle and sucks the titanium phosphate solution is suitable. In the two-fluid spray type sprayer, when the diluent vaporized by the vaporizer is injected from the first nozzle, the titanium phosphate solution is sucked and atomized from the second nozzle by the injected vapor flow, and the titanium phosphate solution Is sprayed together with a diluent, the titanium phosphate liquid can be maintained at a concentration equal to or higher than the non-precipitation concentration of the precipitated solid, the second nozzle through which the titanium phosphate liquid is sucked is not easily clogged, and the titanium phosphate The liquid particles can be sprayed to the distance with a little electric power together with the liquid particles of the diluent, and the antibacterial deodorizing treatment in a room with a large space such as a factory can be performed with a few sprayers, which is excellent in energy saving. Because.
Moreover, the atomizer provided with the ionizer can also be used. Thereby, an electric charge can be given to the sprayed liquid particle and the adhesiveness to objects, such as a wall and a ceiling, can be improved.

Invention of Claim 3 of this invention is the indoor antibacterial deodorizing method of Claim 1 or 2, Comprising: Before the said chemical | medical solution spraying process, water is sprayed in the said room and the said room is humidified. It has the structure provided with the indoor humidification process.
With this configuration, in addition to the operation obtained in the first or second aspect, the following operation can be obtained.
(1) Humidify the room and adjust the surface of all objects such as walls, ceilings, floors, tatami mats, carpets, windows, furniture, etc. to a humid atmosphere, and then spray titanium phosphate solution into the room Therefore, it is possible to reliably attach water-soluble titanium phosphate compounds to the target without being affected by the season, the weather, the material of the target, etc., even if the amount of titanium phosphate applied is small. In addition, a uniform and strong titanium phosphate-based compound coating can be formed on the surface of the object, and antibacterial and deodorizing effects can be maintained for a long period of time. When the titanium phosphate solution is sprayed with the room dry, the surface of the object is also dry, so the titanium phosphate solution adhering to the object dries quickly and the titanium phosphate compound is difficult to diffuse. It becomes difficult to form a film with a uniform thickness on the object, and liquid spots are likely to occur, so a large amount of titanium phosphate solution is required, and the material of the object is a water-absorbing material or a water-repellent material. Depending on the material, the penetration depth of the titanium phosphate solution differs depending on the material, and the thickness and homogeneity of the coating differ from material to material. This is because the odor action becomes poor.
(2) Since the surface of the indoor object is adjusted to a high humidity atmosphere and the titanium phosphate liquid is sprayed into the room, the atomized titanium phosphate liquid is easily fixed on the surface of the object. The titanium phosphate solution provides a great antibacterial and deodorizing effect, and since a small amount of the titanium phosphate solution is sufficient, the titanium phosphate solution can be used without waste, and is excellent in resource saving.

Here, tap water, purified water, ion exchange water, distilled water, electrolyzed water, etc. are used as water sprayed indoors. This is because there are few germs. In particular, purified water, ion exchange water, distilled water, electrolyzed water and the like are preferably used. This is for preventing calcium and the like in the water from depositing on the nozzle of the sprayer and clogging.
Further, water in which a fragrance, a preservative, or the like is dissolved can be used. A fragrance can give a fragrance indoors to enhance comfort, and a preservative can enhance storage stability.
Further, by dissolving the surfactant, the wettability to the object can be increased, and the diffusion of the sprayed titanium phosphate compound can be promoted. As the surfactant, various types such as a cationic surfactant, an amphoteric surfactant, and a nonionic surfactant are used. The mixing ratio of the surfactant is preferably 0.01 to 0.05% by volume with respect to the total amount. As the blending ratio becomes less than 0.01% by volume, the surface tension of water is less likely to decrease and the effect of improving the wettability tends to be poor, and as the content exceeds 0.05% by volume, the tendency to become easier to aggregate. Therefore, neither is preferable.

The spraying time in the indoor humidification step is about 5 to 10 minutes in the case of an automobile interior. When antibacterial deodorizing treatment is performed in a large room such as a factory, the number of sprayers to be placed in the room and the spraying time can be appropriately selected in consideration of the flight distance of liquid particles according to the size of the room. it can.
In the indoor humidification step, it is preferable to close the windows and close the room. This is to keep the room at high humidity during the work. Moreover, it is preferable to perform it in the state which stopped the air conditioner. This is to prevent the generation of airflow in the room and to spray water uniformly in the room.

Invention of Claim 4 of this invention is the indoor antibacterial deodorizing method of any one of Claim 1 thru | or 3, Comprising: It was humidified by the said indoor humidification process, or the said chemical | medical solution spraying process The relative humidity in the room where the chemical solution is sprayed is 65 to 95%, preferably 70 to 90%.
According to this configuration, in addition to the action obtained in any one of claims 1 to 3, the following action is obtained.
(1) Since the indoor relative humidity is 65 to 95%, the water-soluble titanium phosphate compound can be reliably attached to the object without being affected by the season, weather, or the material of the object. A uniform and strong titanium phosphate compound coating can be formed on the surface of the object.

  Here, as the indoor relative humidity becomes lower than 70%, depending on the material of the object, the titanium phosphate compound is less likely to adhere, and it tends to be difficult to form a uniform and strong film. As it becomes higher than 90%, there is a tendency that problems such as high humidity in the room and longer drying time, and generation of something that gets wet and deteriorates tend to occur, depending on the type of the object. In particular, if it is lower than 65% or higher than 95%, these tendencies become remarkable, so that neither is preferable.

Invention of Claim 5 of this invention is the indoor antibacterial deodorizing method of any one of Claim 1 thru | or 4, Comprising: The said water and / or said dilution sprayed in the said indoor humidification process The agent has a structure in which alcohols and / or catechins are dissolved.
With this configuration, in addition to the action obtained in any one of claims 1 to 4, the following action is obtained.
(1) Since alcohols and catechins are dissolved in water and diluent sprayed in the indoor humidification process, the antibacterial action of alcohols and catechins can inhibit the growth and survival of mold and microorganisms. Antibacterial properties can be increased.

Here, as the alcohol, ethanol having 2 to 4 carbon atoms, isopropyl alcohol, or the like can be used. The alcohols are preferably mixed with water or a diluent at a rate of 5 to 30% by volume. This is because the antibacterial effect tends to decrease as it becomes thinner than 5% by volume, and the concentration tends to evaporate as it becomes thicker than 30% by volume, and the humidity in the room tends to become difficult to increase.
In particular, vaporization and spraying using a vaporizer is preferable because water and diluent are easily vaporized by mixing alcohols, and fine liquid particles can be sprayed uniformly.
As the catechins, extracts of plant bodies such as wood, bark and leaves are used, and particularly extracts from tea leaves are preferably used. It is because it is excellent in antibacterial properties. The catechins are preferably mixed with water or a diluent at a ratio of 0.1 to 1% by volume. This is because the antibacterial effect tends to decrease as it becomes thinner than 0.1% by volume, and even if it is thicker than 1% by volume, the antibacterial effect does not tend to increase and the running cost increases.

Invention of Claim 6 of this invention is the indoor antibacterial deodorization method of any one of Claim 1 thru | or 5, Comprising: The blower outlet and / or suction of the air conditioner installed in the said room | chamber interior In the mouth, before the indoor humidification step or the chemical solution spraying step, a sterilization treatment step in an air conditioner that introduces a sterilizing agent to sterilize, and the indoors in which the chemical solution is sprayed after the chemical solution spraying step And a drying processing step of operating and drying the apparatus.
With this configuration, in addition to the action obtained in any one of claims 1 to 5, the following action is obtained.
(1) After the bactericidal agent is introduced into the air conditioner and sterilized, the room sprayed with the chemical solution is dried by operating the air conditioner, so that the room is dried in a short time and titanium phosphate is applied to the surface of the object. Since the coating film of the system compound can be formed in a short time, the productivity of the antibacterial deodorizing treatment is excellent.
(2) After the air conditioner is sterilized in the air conditioner sterilization process, the titanium phosphate solution is sprayed indoors in the chemical spraying process, and then the air conditioner is operated. Since the titanium phosphate liquid is sucked into the air conditioner, a coating film of the titanium phosphate compound can be formed on the surface and inside of the air conditioner.
(3) Since the inside of the air conditioner is sterilized in advance, there is almost no mold, microorganisms, or odors in the air current blown from the air conditioner into the room in the drying process, and the titanium phosphate solution is sprayed. It is possible to dry the interior of the room with an air stream with a reduced clean odor.

  Here, as the disinfectant, alcohols such as ethanol and isopropyl alcohol, halogens such as chlorine, hypochlorous acid, chlorine dioxide and chlorine dioxide aqueous solution, hydrogen peroxide, ozone, ozone water in which ozone is dissolved, Oxygens such as ethylene oxide and propylene oxide are used. Of these, ozone and chlorine dioxide aqueous solution are preferably used. This is because it is relatively easy to handle, has strong oxidizing power and high bactericidal ability, and has high ability to decompose odorous components such as hydrogen sulfide and methyl mercaptan.

  In the air-conditioner sterilization process, the air-conditioner is preferably set to a state of inside-air circulation and heating operation. This is because the antibacterial treatment effect is enhanced by introducing the disinfectant deep inside the air conditioner by the inside air circulation, and the disinfecting power of the disinfectant tends to increase as the temperature in the air conditioner increases.

The drying treatment step is not performed immediately after the chemical spraying step, but is performed after leaving the chemical spraying step and standing for a while (about 10 to 20 minutes). This is to wait for the mist-like titanium phosphate liquid floating in the air to settle on the object.
In the drying process, the air conditioner is preferably set to a state of inside air circulation and heating operation. This is because the titanium phosphate solution is dried in a short time, and as the room temperature increases, the adhesion of the titanium phosphate compound coating tends to increase.

The chemical solution according to claim 7 of the present invention has a configuration containing a titanium phosphate compound or a condensate thereof, and catechins.
With this configuration, the following effects can be obtained.
(1) Since it contains a titanium phosphate compound or its condensate, it reduces airborne bacteria and harmful bacteria present in indoor living spaces without affecting the human body, decomposes odors, Can prevent the generation of various bacteria for a long time, prevention of atopy, allergy, hay fever, asthma, deodorization of pet odor and tobacco odor, reduction of mold caused by moisture and condensation, prevention of infection in medical facilities and educational facilities, tobacco The effect of preventing the adhesion of scum can be maintained for a long time, and the application range is wide and the versatility is excellent.
(2) Since catechins are contained, the quick action antibacterial action of catechins can inhibit the growth and survival of molds and microorganisms, and can enhance antibacterial properties.

Here, since the titanium phosphate compound or its condensate has been described in claim 1, the description thereof is omitted.
As the catechins, extracts of plant bodies such as wood, bark and leaves are used, and particularly extracts from tea leaves are preferably used. It is because it is excellent in antibacterial properties. The catechins are preferably contained in the chemical solution at a ratio of 0.1 to 1% by volume. This is because the antibacterial effect tends to decrease as it becomes thinner than 0.1% by volume, and even if it is thicker than 1% by volume, the antibacterial effect does not tend to increase and the running cost increases.

  As the chemical solution, a titanium phosphate compound or a condensate thereof, or catechins dissolved or dispersed in water, alcohol, or a mixed solution of water and alcohol is used. For example, a solution in which catechins are dissolved in a titanium phosphate solution described in claim 1 can be used. Furthermore, a fragrance | flavor, antiseptic | preservative, surfactant, etc. can also be mixed. The fragrance can release fragrance in the room to enhance comfort, the preservative can enhance the storage stability, the surfactant can increase the emulsifiability of catechins and the wettability to the object. preferable.

Invention of Claim 8 of this invention is a chemical | medical solution of Claim 7, Comprising: It has the structure containing chlorine dioxide.
With this configuration, in addition to the operation obtained in the seventh aspect, the following operation can be obtained.
(1) Chlorine dioxide in the chemical solution is relatively easy to handle because it hardly produces halogen compounds and has almost no toxicity, and is excellent in preservability, has strong oxidizing power and high bactericidal ability. High decomposing ability of odorous components such as methyl mercaptan and excellent deodorizing action can be obtained.

  Here, 10-100 ppm is suitable for the density | concentration of the chlorine dioxide in a chemical | medical solution. As the concentration is lower than 10 ppm, the sterilization / deodorizing action tends to be poor, and as the concentration is higher than 100 ppm, although there is a tendency to feel an unpleasant odor, neither is preferable.

After closing and sealing all the windows (8 tatami mats) in one room of a newly built condominium, 160ml of purified water was sprayed into the room for 8 minutes using an electric sprayer with the air conditioner stopped (in the room) Humidification process). The indoor temperature before spraying purified water was 20 ° C. and the relative humidity was 63%, and the indoor temperature after spraying purified water was 22 ° C. and the relative humidity was 83%. Immediately thereafter, 160 mL of a titanium phosphate liquid (trade name: Ecochimera (registered trademark) SW-50) containing a titanium phosphate compound as an active ingredient was added using an electric sprayer of a two-fluid spray system equipped with a vaporizer. Sprayed with purified water (diluent) for 16 minutes (chemical solution spraying step). After the chemical spraying process, the room was dried.

(Example 2)
Titanium phosphate system without humidifying the room with the air conditioner stopped after all windows and doors in another room (8 tatami mats) of the same newly constructed apartment as Example 1 were closed and sealed. Using a two-fluid spray type electric sprayer equipped with a vaporizer, 160 mL of purified water (diluent) of 160 mL of titanium phosphate solution (trade name: Ecochimera (registered trademark) SW-50) containing the compound as an active ingredient And sprayed for 16 minutes (chemical solution spraying step). After spraying the chemical solution, the room was dried. The room temperature before spraying was 20 ° C. and the relative humidity was 59%, the room temperature after spraying was 20 degrees, and the relative humidity was 83%.

(Measurement of formaldehyde concentration in the room)
Before spraying the titanium phosphate solution and 24 hours after spraying, the formaldehyde concentration in the air in the rooms of Example 1, Example 2, and Comparative Example 1 was measured. The measurement was performed before spraying and 24 hours after spraying, after opening all windows and all doors and ventilating for 30 minutes, and then completely sealing and after 5 hours had passed. In addition, a titanium phosphate solution (trade name: Ecochimera (registered trademark) SW-50) containing a titanium phosphate-based compound as an active ingredient is placed in another room (8 tatami mats) in the same newly built apartment building as in Example 1. The case of not spraying was designated as Comparative Example 1.
The measurement results of formaldehyde concentration are shown in (Table 1).

As shown in (Table 1), it was found that Example 1 and Example 2 had a lower indoor formaldehyde concentration than Comparative Example 1. In particular, it was found that Example 1 in which the room was humidified before spraying the chemical solution had a lower formaldehyde concentration than Example 2. As described above, according to the present example, even a small amount of 160 mL of titanium phosphate solution can form a uniform and strong titanium phosphate compound film on the surface of an object in a room. It was revealed that formaldehyde, which is a causative substance, can be decomposed to greatly reduce the concentration in the air.
In addition, the case where the spray treatment was performed in the same manner as in Example 2 except that a chemical solution in which a titanium phosphate solution and purified water (diluent) were mixed in advance was used and this chemical solution was sprayed using a one-component sprayer. The antibacterial deodorizing effect was examined, and the result was the same as in Example 2. However, it was found that the nozzle of the sprayer was easily clogged and the workability was slightly lowered.
Further, the antibacterial effect when spraying was performed in the same manner as in Example 2 except that a chemical solution in which 0.5% by volume of catechin was dissolved in a mixture of titanium phosphate solution and purified water (diluent) was used. The odor effect was the same as in Example 2. However, the deodorant property immediately after spraying the chemical was superior to that in Example 2. This was thought to be due to the addition of catechin.

(Example 3)
After closing and sealing all windows and doors of a bathroom (about 6 tatami mats) in a newly-built apartment, 120 mL of purified water was sprayed into the room for 6 minutes using an electric sprayer with the air conditioner stopped ( Indoor humidification process). The indoor temperature before spraying purified water was 18 ° C. and the relative humidity was 56%, and the indoor temperature after spraying purified water was 20 ° C. and the relative humidity was 80%. Immediately thereafter, 120 mL of a titanium phosphate solution (trade name: Ecochimera (registered trademark) SW-50) containing a titanium phosphate compound as an active ingredient was added using a two-fluid spray type electric sprayer equipped with a vaporizer. Sprayed with purified water (diluent) for 12 minutes (chemical solution spraying step). After the chemical spraying process, the room was dried.

Example 4
Titanium phosphate without humidifying the room with the air conditioner stopped after all windows and doors of another bathroom (about 6 tatami mats) of the same newly constructed apartment as Example 3 were closed and sealed. Titanium phosphate solution (trade name: Ecochimera (registered trademark) SW-50) containing 120 ml of an active compound as an active ingredient, 120 mL of purified water (diluent) using a two-fluid spray type electric sprayer equipped with a vaporizer ) For 10 minutes. After spraying the chemical solution, the room was dried. The room temperature before spraying was 18 ° C. and the relative humidity was 56%, and the room temperature after spraying was 18 ° C. and the relative humidity was 80%.

(Evaluation of mold resistance)
The bathrooms treated in Example 3 and Example 4 were cured for 48 hours after spraying and then bathed every night for 3 months to use the bathroom. After taking a bath, the bathroom was not cleaned. In addition, a bathroom that was not sprayed with the titanium phosphate solution was prepared separately, and the bath was used in the same manner. This was designated as Comparative Example 2.
As a result, mold occurred on the wall, ceiling, and floor of the bathroom treated in Comparative Example 2 after about one month, whereas the bathroom treated in Example 3 did not have mold even after three months. Did not occur. In the bathroom where the treatment of Example 4 was performed, mold was slightly generated on the wall surface and ceiling.
As described above, according to the present embodiment, it is possible to form a uniform and strong titanium phosphate-based coating film in a room simply by spraying a small amount of a titanium phosphate solution, and to generate mold and bacteria in the room. It became clear that can be prevented for a long time.

(Example 5)
The antibacterial deodorizing treatment was performed in the interior of a normal passenger car with a room temperature of 25 ° C. and a relative humidity of 50% kept in the shade. At first, the air conditioner (air conditioner) was set to the inside air circulation, heating operation, maximum air volume, and maximum temperature. Next, 50 mL of chlorine dioxide aqueous solution was sprayed from the suction port of the air conditioner as a disinfectant using a sprayer (sterilization process in the air conditioner). After spraying the disinfectant, the air conditioner was stopped.
Next, an electric sprayer was placed on the driver's seat, and with all doors and windows closed, 60 mL of a mixed solution of purified water and ethanol was sprayed for 6 minutes toward the rear seat (indoor humidification step). The indoor relative humidity at this time was 83%.
Immediately thereafter, 60 mL of a titanium phosphate solution (trade name: Ecochimera (registered trademark) SW-50) containing a titanium phosphate compound as an active ingredient was purified using a two-fluid spray type electric sprayer equipped with a vaporizer. It sprayed for 12 minutes with 60 mL of the mixed solution (diluent) of water and ethanol (chemical | medical solution spraying process). After completion of spraying, the solution was left as it was for 10 minutes to fix the titanium phosphate solution.
After 10 minutes from the end of spraying, the inside air circulation, the heating operation, the air flow set to the maximum air volume and the maximum temperature were operated, and the room was dried for 5 minutes (drying process step).
As a result, pet odors and cigarette odors drifting in the room disappeared, and odors such as the unique mold odor generated from the air conditioner disappeared. After that, the car was operated normally while smoking, but no tobacco odor was generated from the room even after 1 month. Moreover, the tobacco scum did not adhere to the wall surface or the like.

(Example 6)
Example 6 was obtained by performing antibacterial deodorizing treatment in a room of a normal automobile in the same manner as in Example 5 except that the indoor humidification step was not performed before spraying the titanium phosphate solution. Also in the case of Example 6, the relative humidity in the room after chemical spraying was 83%.
Immediately after the treatment, the pet odor and cigarette odor drifting in the room disappeared, and the odor such as the unique mold odor generated from the air conditioner disappeared. While driving normally while smoking cigarettes, after about 20 days, the smell of cigarettes started to become noticeable, but until then, no smell of cigarettes was felt.
As described above, according to this embodiment, it is possible to form a uniform and strong titanium phosphate-based compound coating on the surface of an indoor object by simply spraying a small amount of titanium phosphate solution. It has become clear that malodors such as tobacco odor and pet odor can be decomposed and this effect can be sustained for a long time.
