Description
Technical Field
The present invention relates to a living space treating agent for a piezoelectric atomizer.
The present application claims priority based on japanese patent application No. 2015-019350 filed in japan on 3/2/2015, and the contents thereof are incorporated herein by reference.
Background
The places difficult to reach such as ceilings and upper parts of walls of bathrooms are places where the treatment of the spray type chlorine-based mildew removing agent is difficult and microorganisms such as bacteria and mold are liable to propagate.
In addition, microorganisms are likely to grow in living spaces, even in various places other than water-using places such as bathrooms (for example, hallways, window frames, closets, western-style closets (closets), and the like). However, in such a place, the cleaning agent cannot be easily washed with water, and the treatment of the chlorine-based fungicide is difficult.
Further, since microorganisms propagate in various places, if only local applications such as wiping a sterilization spray are applied, the mold-proof effect is insufficient and the use is not smooth.
Therefore, a method for easily maintaining a clean space by removing microorganisms from various locations in the living space and preventing the microorganisms from propagating is desired.
For such a demand, a proposal has been made for: a smoke type mildewcide is used as a method for spraying an inorganic chemical (antibacterial agent) such as silver with a high mildewproof effect into the whole space in a light manner.
However, in recent years, in consideration of use in various places of living spaces, a method of mildew-proof treatment is being sought which suppresses the amount of smoke or does not generate smoke.
Therefore, a method of spraying a chemical liquid into a space by a piezoelectric type atomizer has been proposed. The piezoelectric atomizer atomizes a chemical liquid by ultrasonic vibration using a piezoelectric element, and is more convenient to use than a manual atomizing type and can atomize a chemical liquid. In addition, the piezo type atomizer has a smaller smoke amount than the heat evaporation type atomizer.
As a space treatment agent using a piezo-electric atomizer, for example, patent document 1 discloses a liquid chemical for a piezo-electric atomizer containing an organic chemical such as transfluthrin and an organic solvent having a boiling point of 150 to 250 ℃ as an insect control agent.
Patent document 2 discloses a method for repelling crawling insects by evaporating an insecticide liquid containing an insecticide component and an organic solvent such as an ethylene glycol-based solvent or a propylene glycol-based solvent in a space using a piezoelectric atomizer.
Further, patent document 3 discloses the following method: a method for spraying a deodorizing/perfuming agent comprising impregnating or dispersing a support comprising an ethylene-vinyl acetate copolymer and a fragrance component and metal ions in an aqueous solvent having a boiling point of less than 200 ℃ by using an ultrasonic sprayer.

Hereinafter, an embodiment of the present invention will be described in detail.
The living space treating agent for a piezoelectric atomizer of the present invention (hereinafter, simply referred to as "space treating agent") is a liquid composition containing the following component (a), component (B), and component (C). In addition, it is preferable that the space treatment agent is a liquid composition further containing the component (D) described below.
The content of all components contained in the space treatment agent is 100% by mass in total.
< component (A) >
(A) The component (A) is an inorganic chemical containing a transition metal. By using the component (A), a mold-proof effect is obtained. By obtaining the mold-proof effect, odor caused by the proliferation of microorganisms can be suppressed, and a deodorizing effect can be obtained.
Here, the "transition metal-containing inorganic drug" refers to a drug containing at least 1 selected from the group consisting of a transition metal monomer and a compound thereof (transition metal compound) as an active ingredient.
Examples of the transition metal monomer include silver, zinc, copper, and nickel.
Examples of the transition metal compound include an oxide of a transition metal, and a salt of a transition metal ion and a counter ion. Examples of the salt include chloride, nitrate, sulfate, gluconate, sulfonate, carbonate, formate, and acetate.
The component (a) is preferably silver, zinc, copper or a compound thereof, and more preferably silver or a silver compound, because of its excellent antifungal effect and deodorant effect.
Further, as the component (a), a transition metal monomer or a transition metal compound supported on a carrier (hereinafter, also referred to as "carrier") may be used.
Examples of the carrier include zeolite, silica-alumina, silica gel, low-molecular glass, calcium phosphate, silicate, and titanium oxide.
Examples of the carrier include: zeolite-based inorganic antibacterial agents, silica-alumina-based inorganic antibacterial agents, silica-gel-based inorganic antibacterial agents, titanium oxide-based inorganic antibacterial agents, silicate-based inorganic antibacterial agents, and the like, each of which is supported by a transition metal monomer or a transition metal compound such as silver oxide, silver nitrate, copper sulfate, zinc chloride, and the like. By using such a supporting body as the component (a), uniform smoking treatment of the surface becomes possible, and a stable antifungal effect can be exerted. By using such a supporting body as the component (a), uniform smoking treatment of the surface becomes possible, and a stable antifungal effect can be exerted.
(A) The form of the component is not particularly limited, and may be determined in consideration of the width of the target space and the like. The finer the particles of component (a), the more the effect of component (a) can be fully exerted and the more widely diffused component (a) can be. On the other hand, if the particle size of component (a) is too small, it becomes difficult to fall after diffusion, and it takes time for the effect of component (a) to be expressed below the target space.
For example, when the component (A) is a carrier, the volume average particle diameter of the component (A) is preferably 0.01 to 10 μm, more preferably 0.01 to 1 μm, and still more preferably 0.01 to 0.1. mu.m.
The volume average particle diameter is a value obtained by a laser diffraction/scattering particle size distribution measuring apparatus, and can be measured as follows. The sample was prepared by dispersing component (a) in distilled water so that the solid content was 1 mass%. This sample was put into a laser diffraction/scattering particle size distribution measuring apparatus, and dispersed in the apparatus by ultrasonic waves, and then irradiated with laser light to measure the particle size distribution. The particle diameter at which the cumulative volume frequency is 50% by volume is the average particle diameter.
(A) The component (A) may be used alone in 1 kind or in combination of 2 or more kinds.
The content of the component (a) in the space treatment agent is determined depending on the kind or concentration of the active ingredient in the component (a) and the function required for the space treatment agent.
The content of the component (A) is preferably 0.001 to 1.0% by mass, more preferably 0.05 to 0.1% by mass, in terms of the amount of the transition metal monomer, based on the total mass of the space-treating agent. When the content of the component (a) is 0.001% by mass or more, the mold-proof effect can be sufficiently obtained. On the other hand, even if the content of the component (a) exceeds 1.0 mass%, further improvement of the effect cannot be expected.
When the component (A) is a carrier, the content of the component (A) as a carrier is preferably 0.01 to 5% by mass, more preferably 0.1 to 2% by mass. When the content of the component (a) is 0.01% by mass or more, the mold-proof effect can be sufficiently obtained. On the other hand, when the content of the component (a) is 5 mass% or less, a decrease in the spraying force due to clogging of the piezo-electric sprayer can be suppressed.
< ingredient (B) >
(B) The component (A) is an organic solvent having a boiling point of 70 ℃ or higher but less than 150 ℃. By using the component (B), the volatility and the diffusibility of the component (A) are improved when the piezoelectric atomizer is used, and a uniform antifungal effect can be expressed in the entire treatment space. If the boiling point of the component (B) is less than 70 ℃, the component (B) naturally evaporates, the concentration of the space treatment agent becomes too high, clogging of the piezoelectric atomizer tends to occur, and the spraying force may be reduced for a long time.
(B) The boiling point of the organic solvent in the component (A) is preferably 75 ℃ or higher, and preferably 120 ℃ or lower.
Examples of the component (B) include ethanol, 2-propanol, ethylene glycol dimethyl ether, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monomethyl ether acetate, propylene glycol monomethyl ether, and propylene glycol monoisopropyl ether. Among them, ethanol is preferred.
(B) The component (A) may be used alone in 1 kind or in combination of 2 or more kinds. When 2 or more organic solvents are used in combination, the boiling points of the organic solvents used as component (B) are 70 ℃ or more and less than 150 ℃.
The content of the component (B) in the space treatment agent is preferably 10 to 50% by mass, more preferably 10 to 30% by mass, based on the total mass of the space treatment agent. When the content of the component (B) is within the above range, the volatility and diffusibility of the component (a) become better, and the antifungal effect is further improved. In particular, when the content of the component (B) is 10% by mass or more, the volatility and the diffusion of the component (a) become more favorable. On the other hand, when the content of the component (B) is 50% by mass or less, the adhesion of the component (a) to a target surface such as a ceiling or a wall can be maintained well, and the durability of the antifungal effect can be further improved.
< ingredient (C) >
(C) The component (A) is an organic solvent having a boiling point of 150 ℃ or higher but less than 250 ℃. By using the component (C), the dispersibility of the component (a) in the space treatment agent is improved. In addition, the adhesion and diffusion of the component (a) after spraying to the target surface are improved, and a uniform antifungal effect can be maintained throughout the entire processing space. If the boiling point of the component (C) exceeds 250 ℃, the volatility or diffusivity of the component (A) is lowered, and the antifungal effect cannot be sufficiently exhibited. Further, there is a concern that the component (C) may affect the target surface (for example, discoloration) when it adheres to the target surface.
(C) The boiling point of the organic solvent in the component (A) is preferably 160 ℃ or higher, and preferably 220 ℃ or lower.
Examples of the component (C) include ethylene glycol, propylene glycol, diethylene glycol dimethyl ether, triethylene glycol monomethyl ether, ethylene glycol diacetate, propylene glycol diacetate, dipropylene glycol dimethyl ether, dipropylene glycol, and isoparaffins (specifically, "Neothiozol (ネオチオゾール)" manufactured by Kakkonto Kabushiki Kaisha, and "IP SOLVENT (IP ソルベント)" manufactured by Kaisha). Among them, propylene glycol is preferred.
(C) The component (A) may be used alone in 1 kind, or may be used in combination in 2 or more kinds. When 2 or more organic solvents are used in combination, the boiling points of the organic solvents used as component (C) are 150 ℃ or more and less than 250 ℃.
The content of the component (C) in the space treatment agent is preferably 45 to 80 mass%, more preferably 50 to 75 mass%, based on the total mass of the space treatment agent. When the content of the component (C) is within the above range, the adhesion of the component (a) to the object surface becomes good, and the durability of the antifungal effect is further improved. In particular, when the content of the component (C) is 45% by mass or more, the adhesion of the component (a) to a ceiling, a wall, or the like is further improved, and the durability of the antifungal effect is further improved. On the other hand, when the content of the component (C) is 80% by mass or less, the diffusibility of the component (a) can be maintained well.
The content of the component (C) in the space treatment agent is an amount such that the mass ratio of the component (B)/the component (C) is 0.1 to 1.0, preferably 0.2 to 0.5. When the mass ratio is within the above range, the volatility and the diffusivity of the component (a) are improved. Further, the adhesion and diffusion of the component (a) after spraying to the target surface are improved, and the durability of the antifungal effect is improved. In particular, when the mass ratio is 0.1 or more, the volatility and the diffusivity of the component (a) due to the component (B) are improved. The component (A) uniformly adheres to the surface of the object, and can sufficiently exhibit the antifungal effect. On the other hand, when the mass ratio is 1.0 or less, the adhesion of the component (a) to the target surface due to the component (C) is improved, and the durability of the antifungal effect is improved.
< ingredient (D) >
(D) The ingredient is a nonionic surfactant. By using the component (D), the uniform diffusibility of the component (a) on the surface of the object is further improved, the antifungal effect (especially, fungicidal effect) is further improved, and the durability of the antifungal effect is further improved.

On the other hand, when the content of the component (D) is 3.0 mass% or less, clogging of the piezo-electric atomizer can be suppressed, and more sufficient volatility can be obtained.
The content of the component (D1) in the component (D) is preferably 60 to 100% by mass, more preferably 80 to 100% by mass, based on the total mass of the component (D). When the content of the component (D1) is 60% by mass or more, the uniform dispersibility of the component (a) in the space-treating agent is further improved.

When the mass ratio is within the above range, the volatility and diffusivity of the component (a) are further improved. In addition, the adhesion and diffusion of the component (a) after spraying to the target surface are improved, and the durability of the antifungal effect is further improved. In particular, when the mass ratio is 10 or more, the volatility and the diffusivity of the component (a) are improved. The component (A) is likely to be uniformly adhered to the surface of the object, and the antifungal effect can be sufficiently exhibited. On the other hand, when the mass ratio is 800 or less, the adhesion of the component (a) to the target surface is improved, and the durability of the antifungal effect is improved.
< optional component >
The space treatment agent may contain any component such as water or perfume component as long as the effect of the present invention is not impaired.
When the space treatment agent contains water, the content of water is preferably 0.1 to 10% by mass based on the total mass of the space treatment agent.

The Perfume ingredients are not particularly limited, and a list of Perfume raw materials that can be used is described in various documents, such as Perfune and Flavor Chemicals, Vol.I and II, Steffen Arctander, Alluded pub.Co. (1994); one of the available knowledge of synthetic spice chemistry and commercial products (synthetic spice chemistry と, available from ), Indian meal gypeng (1996); perfun and flavour Materials of Natural Origin, Steffen Arctander, Allured pub. Co.

(1993), and the like.
< manufacturing method >
The space-treating agent can be produced by, for example, mixing the component (a), the component (B), the component (C), and if necessary, the component (D) with an optional component.
< method of use >
The space treatment agent may be prepared by mixing the component (a), the component (B), the component (C), and, if necessary, the component (D) with an optional component, and then filling the mixture in a piezoelectric atomizer for use.
The amount of the space treatment agent to be filled in the piezoelectric atomizer is determined by the width of the space to be treated, the area of the surface to be treated (target surface), and the like, and is, for example, 1m per space3The amount of the component (A) in the space to be treated of (1) is preferably 0.02 to 20mg, more preferably 0.2 to 5mg, as the monomer concentration of the transition metal.
The piezoelectric atomizer is not limited, and conventionally known piezoelectric atomizers can be used.
Hereinafter, an embodiment of the piezoelectric atomizer will be described with reference to fig. 1. However, the piezo-electric atomizer according to the present invention is not limited to the present embodiment, and the shape of the container and the like may be appropriately modified.
FIG. 1 is a cross-sectional view showing one embodiment of a piezo aerosol.
The piezoelectric atomizer 10 of this example includes a container 11 containing a space treatment agent a, a rod-shaped liquid absorption core 12, an ultrasonic vibrator 13, and an ultrasonic vibrator 14.
The wick 12 has an upper end protruding from the upper opening of the container 11 and a lower end immersed in the space treatment agent a in the container 11, and is supported by a wick support 15 fitted into the upper opening of the container 11. The upper end of the liquid suction core 12 is connected to the ultrasonic transducer 13 via a bonding sheet 16.
The material of the wick 12 is preferably a material having a large surface tension, for example, sponge, (felt), cotton, and a porous material. In particular, from the viewpoint of exerting a liquid-absorbing function only when ultrasonic waves are applied and exerting a plugging function when ultrasonic waves are not applied, a porous material is preferable, and among these, a molded body formed of a mixture of carbonaceous fine powder and a binder is more preferable.
Examples of the material of the bonding sheet 16 include metal and ceramic.
The material of the core support 15 is not particularly limited.
The ultrasonic vibrator 14 is connected to the ultrasonic vibrator 13 and a power source (not shown). Examples of the power source include a battery.
The method of using the space treatment agent using the piezoelectric atomizer 10 shown in fig. 1 is as follows.
First, a certain amount of the space treatment agent a is contained in the container 11, and the space treatment agent a is sufficiently absorbed up to the upper end of the wick 12. In this state, the ultrasonic vibrator 14 is operated, and a signal is transmitted from the ultrasonic vibrator 14 to the ultrasonic transducer 13, thereby generating ultrasonic vibration in the ultrasonic transducer 13 and the bonding pad 16. Accordingly, ultrasonic vibration energy of a viscosity equal to or higher than the surface tension of the spatial treatment agent a is supplied to the upper end of the liquid absorbent core 12, and the spatial treatment agent a is sprayed from the liquid absorbent core 12 into the air.
The frequency of the ultrasonic vibrator 14 is preferably 30 to 500 kHz.
The spraying of the space treatment agent a may be continuous, or may be intermittent spraying in which the driving and stopping are alternately performed.
The amount of the space treatment agent A sprayed by 1 time of driving is preferably 0.01 to 1. mu.L.
In the piezoelectric atomizer 10 shown in fig. 1, the joining piece 16 is not provided, and the upper end of the liquid suction core 12 may be in direct contact with the ultrasonic transducer 13.
Further, although the use of the air blower can also improve the diffusibility of the space treatment agent, it is preferable to spray the space treatment agent without using the air blower from the viewpoint of suppressing power consumption.
Further, as the piezoelectric atomizer, a commercially available one can be used, and examples thereof include "mesh atomizer NE-U22" manufactured by Ohiorong health medical Co., Ltd. (オムロンヘルスケア Co., Ltd.).
Further, as the piezoelectric atomizer, for example, the atomizer described in Japanese patent laid-open No. 6-320083, Japanese patent laid-open No. 7-24374, Japanese patent laid-open No. 7-256170, etc. can be used.
< action Effect >

< preparation of space treating agent >
The space treatment agents having the compositions shown in tables 2 to 5 were produced by the following procedures. The unit of the amount of each component in tables 2 to 5 is mass%. (A) The amount of the component (c) is the monomer concentration (mass%) of the transition metal in 100 mass% of the steric treating agent. In example 10, the support concentration in 100 mass% of the space treatment agent was 0.1 mass%.
In addition, the "equilibrium" of water means an amount by which the total amount of the space treatment agent becomes 100 mass%.
The components other than water were mixed in accordance with the compositions shown in tables 2 to 5, and water was added so that the total amount became 100% by mass, and further mixed to prepare a space treatment agent.
< making of spraying apparatus >
Using the obtained space treatment agent, a spray device was produced as follows.
A spray device was prepared by filling a container of "Glade deodorant パフパフ" (manufactured by QINGSHENG corporation) with 5g of a space treatment agent.
Using the obtained spray device, the fungicidal effect and the durability of the fungicidal effect were evaluated. The results are shown in tables 2 to 5.
