Description

  The present invention relates to a smoke agent and a smoke device.

Smoke and fumigants (generally referred to as smoke agents) are mainly composed of various combustion agents, foaming agents, etc., or exothermic bases mixed with these, and active pest control agents, etc. Is. The soot agent burns or decomposes the exothermic base during the soot treatment, and the gas and smoke particles generated at this time cause the agent to be ejected and diffused in the air in a short time to control pests, etc. It is an excellent preparation that can be performed and has been widely used conventionally.
Smoke agent generates a large amount of smoke and gas at the time of smoke treatment, so that odors originating from chemicals and exothermic substrates are present in the space subject to smoke treatment (hereinafter sometimes referred to as the target space). Remains.

Conventionally, various proposals have been made to reduce odors derived from smoke agents.
For example, a smoke agent composition containing a drug containing silver and an organic foaming agent has been proposed (for example, Patent Document 1). According to the invention of Patent Document 1, an odor derived from a drug is reduced by using a drug containing silver instead of an organic drug.
Further, for example, a smoke agent composition containing 1 to 20% by weight of a combustion agent and 30 to 70% by weight of a decomposition accelerator has been proposed (for example, Patent Document 2). According to the invention of Patent Document 2, the odor is reduced by reducing the content of the combustion agent and suppressing rapid smoke generation.

However, the fragrance | flavor mix | blended with the smoke agent gradually volatilizes or decomposes | disassembles, and there exists a problem that a masking effect desired and the improvement of palatability cannot fully be aimed at, and aroma becomes weak over time. In addition, when the blending amount of the fragrance is simply increased, there is a problem that the ratio of the drug that can diffuse into the target space (smoke rate) is reduced and the effect of the drug becomes insufficient.
Then, this invention aims at the smoke agent which can fully exhibit the effect of a chemical | medical agent and can suppress deterioration with time of the aroma of a fragrance | flavor favorably.

  As a result of intensive studies, the present inventors have used a drug containing silver, and by containing a specific amount of surfactant and a specific amount of water, the effect of the drug can be sufficiently exerted, and the aroma of the fragrance over time The present invention has been completed by finding that good deterioration can be satisfactorily suppressed.

  That is, the smoke agent of the present invention comprises (A) component: silver-containing drug, (B) component: organic foaming agent, (C) component: 3 to 12% by mass of surfactant, and (D) component. : Perfume, (E) component: It contains 0.1-5 mass% of water, It is characterized by the above-mentioned.

For example, the smoke agent is accommodated in an arbitrary container such as a metal container or a ceramic container, and the smoke agent is directly or indirectly heated. Among them, the method of heating indirectly is preferable. This is because, by indirectly heating the smoke smoke agent, indoor pollution due to the burning residue of the smoke smoke agent can be reduced. Moreover, it is set as the smoke device mentioned later, and you may give a smoke process to object space.
The target space is not particularly limited, and examples include a bathroom, a living room, a closet, and a toilet.

The means for indirectly heating the smoke agent may be any means as long as the component (B) can supply thermal energy capable of causing thermal decomposition to the smoke agent without burning the smoke agent. There is a method in which the smoke agent is stored in a container made of metal and the smoke agent is heated through the metal container.
As a heating method, a conventionally known method can be used, for example, a method of contacting a substance that generates heat upon contact with water and using the reaction heat; iron powder and an oxidizing agent (such as ammonium chlorate). Or a metal and a metal oxide or oxidant having a smaller ionization tendency than the metal, and utilizing the heat of oxidation reaction. Examples of substances that generate heat upon contact with water include calcium oxide, magnesium chloride, aluminum chloride, calcium chloride, and iron chloride. Among these, from the viewpoint of practicality, a method of bringing a substance that generates heat upon contact with water into contact with water and utilizing the reaction heat thereof is preferred, and a method of utilizing the reaction heat between calcium oxide and water is more preferred.

The amount of fumigant may be appropriately set according to the volume of the object space, for example, preferably the target space 1 m ³ per 0.1～2.4G, 0.4 to 2.0 g is more preferable.

(Smoke device)
The smoke device of the present invention contains a smoke agent and includes a heating means for heating the smoke agent contained therein.
A smoke device according to an embodiment of the present invention will be described below with reference to FIG.
A smoke device 10 in FIG. 1 is an indirect heating type smoke device, and includes a housing 12, a heating unit 20 provided in the housing 12, and a smoke agent provided in the housing 12. The unit 32 is schematically configured. The housing 12 includes a substantially cylindrical main body 14, a bottom portion 16, and a lid portion 18. A smoke agent container 30 is provided in the casing 12, and the smoke agent container 30 accommodates the smoke agent and forms a smoke agent part 32.
In the smoke device 10, the heating part 20 is a heating means.

The lid portion 18 has a through hole, and examples thereof include a mesh, a punching metal, and a lattice frame. Examples of the material of the lid portion 18 include metals and ceramics.
The material of the main body 14 is the same as that of the lid 18.

  The smoke agent container 30 functions as a container that houses the smoke agent part 32, and also functions as a heat transfer part that transmits the thermal energy generated in the heating part 20 to the smoke agent part 32. Examples of the smoke agent container 30 include a metal container.

  The heating unit 20 is determined in consideration of the amount of heat necessary for the smoker 32 to smoke, for example, a substance that generates heat by contact with water (for example, calcium oxide) may be accommodated, The iron powder and the oxidant may be separated and accommodated by a partition material, or the metal and a metal oxide or oxidant having a smaller ionization tendency than the metal may be partitioned and accommodated by the partition material. . Among these, those containing a substance that generates heat upon contact with water are preferable, and those containing calcium oxide are more preferable.

 The bottom part 16 can be determined according to the mechanism of the heating part 20, for example, when the heating part 20 is made of a substance (calcium oxide or the like) that generates heat when in contact with water, the bottom part 16 has a nonwoven fabric or A metal mesh or the like can be used. By making the bottom part 16 into a nonwoven fabric or a mesh, water can penetrate into the heating part 20 from the bottom part 16 and can be heated.

  A smoke method using the smoke device 10 will be described. First, the smoke device 10 is installed in the target space. Next, the heating unit 20 generates heat according to the mechanism of the heating unit 20. For example, when the heating unit 20 is made of calcium oxide, the bottom 16 is immersed in water. When the bottom part 16 is immersed in water, the water penetrates the bottom part 16 and comes into contact with calcium oxide, so that the heating part 20 generates heat. When the heating unit 20 generates heat, the smoke agent part 32 is heated via the smoke agent container 30. The smoke agent in the heated smoke agent part 32 generates a gas by decomposition of the component (B), and the (A) component, the (C) component, and the (D) component are smoked together with the generated gas, and the lid 18 It passes through the through hole and diffuses into the target space.

In the above-described embodiment, the indirect heating type smoke smoke device has been described as an example of the smoke smoke device, but the present invention is not limited to this. For example, a direct heating type smoke smoking device similar to the smoke smoking device described in Japanese Patent Application Laid-Open No. 2011-193874 and Japanese Patent Application Laid-Open No. 2002-199834 may be used. The direct heating type smoke device includes a smoke agent portion in which a smoke agent is accommodated, and an igniter that ignites the smoke agent, and the igniter serves as a heating means.
However, since there is no generation of a flame that burns the smoke agent itself, an indirect heating type smoke device is preferred.

As described above, since the smoke agent of the present invention uses the component (A) as a drug, the odor derived from the drug can be reduced.
In addition, since the component (C) and the component (E) are contained, deterioration of the aroma of the component (D) over time can be suppressed.
Furthermore, since content of (C) component and (E) component is a specific range, the effect of (A) component can fully be exhibited, without impairing the smoke rate of (A) component.

<Smoke rate of component (A)>
Prepare a container of “Balsan starting with water [for 6-8 tatami mats] (trade name, manufactured by Lion Co., Ltd.)”, and store 5 g of the smoke agent in each case in the smoke agent container in the container, 37 g of calcium oxide was accommodated in the heating agent accommodating part, and a smoke device similar to the smoke device 10 of FIG. 1 was produced.
A smoke device was placed in a plastic container for water supply containing 23 mL of water and smoked.
After sooting, all the residue in the smoke agent container was collected, and the residue was put into 5% by mass dilute nitric acid to elute the silver component to obtain a measurement sample. The amount of silver remaining without being smoked was determined by quantifying the measurement sample by IPC emission analysis.
For the smoke agent before smoke, the amount of silver (in 5 g of smoke agent) was determined in the same manner as the above residue, and the smoke rate was calculated by the following equation (1). The obtained smoke rate was classified according to the following evaluation criteria.

 Smoke rate (mass%) = [(mass of silver in smoke before smoke) − (mass of silver in residue)] ÷ (mass of silver in smoke before smoke) × 100 ... (1)

≪Evaluation criteria≫
A: Smoke rate is 60% by mass or more.
○: Smoke rate is 40% by mass or more and less than 60% by mass.
Δ: Smoke rate is 20% by mass or more and less than 40% by mass.
X: Smoke rate is less than 20 mass%.

(Examples 1-25, Comparative Examples 1-5)
According to the composition shown in Tables 2 to 4, the components (A), (B), HPMC and clay as powder components were stirred and mixed with a kneader (S5-2G type, manufactured by Moriyama Co., Ltd.) at 20 ° C. did. A mixture of (C) component, (D) component and water (10 parts by mass of water with respect to a total of 100 parts by mass of (A) to (D) components and optional components) previously stirred and mixed is added to the kneader. And mixed to obtain a mixture.
The obtained mixture was granulated using a die pre-extruding granulator (EXK-1, manufactured by Fuji Powder Co., Ltd.) having an opening diameter of 2 mm in diameter to obtain a granulated product. The obtained granulated material was cut into a length of 2 to 5 mm by a flash mill (FL300, manufactured by Fuji Paudal Co., Ltd.), and then in a table by a dryer (RT-120HL, manufactured by Alp Co., Ltd.) set at 70 ° C. The drying time was adjusted so that the amount of the component (E) described was obtained, to obtain a granular smoke agent. About the obtained smoke agent, storage stability and the smoke formation rate of (A) component were evaluated, and the result is shown in a table | surface.
