Description

The present invention relates to spatial aerosol compositions. More specifically, the present invention relates to a spatial aerosol composition in which particles sprayed into a space are diffused to exert the effect, and the falling particles are reduced to prevent the floor surface from getting wet.

Conventionally, a spatial aerosol composition comprising a stock solution obtained by adding an active ingredient such as an insecticidal component to a hydrocarbon solvent such as kerosene and a propellant such as liquefied petroleum gas is known. In this spatial aerosol composition, the sprayed particles diffuse in the space for a while to exert their effect, and then naturally fall. Hydrocarbon-based solvents such as kerosene have problems such as poor drying property, which makes it easy to wet the floor surface and make them slippery. Patent Document 1 discloses an insecticidal aerosol product containing an insecticidal component, liquid paraffin, an HFO-based solvent, and a propellant.

Japanese Unexamined Patent Publication No. 2018-115114

Although the insecticidal aerosol product described in Patent Document 1 uses an HFO-based solvent, it is intended to shorten the knockdown time by containing the HFO-based solvent and liquid paraffin, and the content thereof is extremely high. It is not enough to improve the usability.

The present invention has been made in view of such conventional problems, and the particles sprayed in the space are diffused to exert the effect, and the falling particles are reduced to prevent the floor surface from getting wet. It is an object of the present invention to provide an aerosol composition for a space capable of forming an aerosol.

The present invention that solves the above problems mainly includes the following configurations.

(1) The stock solution is composed of a stock solution and a propellant, and the stock solution contains an oily solvent having a flash point of 30 to 70 ° C. and a hydrofluoroolefin having a boiling point of 25 to 50 ° C., and the content of the hydrofluoroolefin. Is a space aerosol composition which is 5 to 30% by mass in the undiluted solution.

According to such a configuration, the undiluted solution contains a specific amount of an oily solvent having a specific flash point and a hydrofluoroolefin having a specific boiling point. By spraying such a stock solution with a propellant, the particles sprayed into the space have an appropriate particle size and diffuse to exert their effect, and at the same time, volatilization progresses during diffusion and falls to the floor surface. It is possible to prevent the floor surface from getting wet by reducing the number of particles. Further, in the stock solution, the hydrofluoroolefin is easily dissolved in the oil-based solvent, and even if the temperature becomes higher than the boiling point of the hydrofluoroolefin, the hydrofluoroolefin tends to remain in the stock solution. Therefore, the undiluted solution has a high flash point and is highly safe against fire.

(2) The space aerosol composition according to (1), wherein the oil-based solvent contains a hydrocarbon-based solvent.

According to such a configuration, in the stock solution, the hydrofluoroolefin is easily dissolved in the hydrocarbon solvent. Therefore, the particles sprayed into the space are more likely to volatilize, and the number of falling particles is likely to decrease.

(3) The space aerosol composition according to (1) or (2), wherein the content of the propellant is 50 to 90% by mass in the aerosol composition.

According to such a configuration, the particles sprayed into the space tend to have an appropriate particle size, diffuse in the space and exert the effect, and are less likely to volatilize and fall on the floor surface.

According to the present invention, it is possible to provide an aerosol composition for space in which particles sprayed into a space are diffused to exert the effect, and the falling particles are reduced to prevent the floor surface from getting wet. ..

<Aerosol composition for space>
The spatial aerosol composition of one embodiment of the present invention comprises a stock solution and a propellant. The stock solution contains an oily solvent having a flash point of 30 to 70 ° C. and a hydrofluoroolefin having a boiling point of 25 to 50 ° C. The content of hydrofluoroolefin is 5 to 30% by mass in the undiluted solution. Each will be described below.

(Stock solution)
The stock solution contains an oily solvent having a flash point of 30 to 70 ° C. and a hydrofluoroolefin having a boiling point of 25 to 50 ° C.

-Oil solvent having a flash point of 30 to 70 ° C. As the oil solvent, a solvent having a flash point of 30 to 70 ° C. is used. When the flash point is within the above range, the spatial aerosol composition tends to have an appropriate particle size when sprayed into the space, and also tends to volatilize during diffusion in the space, and falls to the floor surface. The effect of reducing the number of adhered particles can be easily obtained. Further, since the oil-based solvent having a flash point of 30 to 70 ° C. is contained, the undiluted solution easily retains the hydrofluoroolefin in the undiluted solution even if the temperature rises to near the flash point of the oil-based solvent, and it is difficult to ignite. Become.

The oil-based solvent having a flash point of 30 to 70 ° C. is not particularly limited. As an example, the oil-based solvent is a naphthenic hydrocarbon such as Exol DSP145 / 160 (flash point 32 ° C.), Exol D40 (flash point 45 ° C.), Exol D60 (flash point 68 ° C.), Norper 10 (flash point 52). Normal paraffin hydrocarbons such as (° C), Idemitsu Supersol FP25 (flash point 49 ° C), Idemitsu Supersol LA25 (flash point 42 ° C), Isopar G (flash point 44 ° C), Isopar H (flash point 54 ° C), Isoparaffin-based hydrocarbons such as Isopar L (flash point 64 ° C), IP solvent 1620 (flash point 49 ° C), IP Clean LX (flash point 45 ° C), Teasol 100 (flash point 48 ° C), Teasol 150 (flash point 66). ℃), aromatic hydrocarbons such as Solbesso 150ND (flash point 64 ℃), mixtures of hydrocarbons such as kerosine (flash point 65-70 ℃), silicone oils such as trisiloxane (flash point 46 ℃), etc. .. Among these, the oil-based solvent preferably contains a hydrocarbon-based solvent because of its excellent solubility of hydrofluoroolefins. When the hydrofluoroolefin is dissolved in a hydrocarbon solvent, the hydrofluoroolefin tends to remain in the stock solution even when the temperature becomes higher than the boiling point of the hydrofluoroolefin. As a result, the stock solution has a higher flash point and is more safe against fire.

The content of the oily solvent having a flash point of 30 to 70 ° C. is not particularly limited. As an example, the oil-based solvent is preferably 30% by mass or more, more preferably 40% by mass or more in the undiluted solution. The oil-based solvent is preferably 93% by mass or less, more preferably 90% by mass or less in the undiluted solution. When the content of the oil-based solvent is within the above range, the stock solution tends to retain the hydrofluoroolefin in the stock solution even if the temperature rises to near the flash point of the oil-based solvent. This makes the undiluted solution less likely to catch fire. In addition, the sprayed particles are likely to volatilize during diffusion, and the effect of reducing the number of falling particles is likely to be obtained.

Hydrofluoroolefins having a boiling point of 25 to 50 ° C. Hydrofluoroolefins having a boiling point of 25 to 50 ° C. dissolve in an oily solvent and make it difficult for the stock solution to ignite. Particles sprayed in the space volatilize during diffusion. It is used for the purpose of facilitating. When the boiling point of the hydrofluoroolefin is within the above range, the undiluted solution is less likely to ignite even if the temperature rises to near the flash point of the oil-based solvent. In addition, the particles sprayed into the space tend to volatilize during diffusion, and the effect of reducing the number of falling particles can be easily obtained.

The hydrofluoroolefin having a boiling point of 25 to 50 ° C. is not particularly limited. As an example, the hydrofluoroolefin having a boiling point of 25 to 50 ° C. is cis-1-chloro-3,3,3-trifluoropropane (HFO-1233zd (Z), boiling point 39 ° C.) and the like. In addition, trans-1-chloro-3,3,3-trifluoro within the range where the effects such as reducing the particle size of the sprayed particles, speeding up the volatilization during diffusion and reducing the number of falling particles can be obtained. Hydrofluoroolefins having a boiling point of less than 25 ° C., such as propane (HFO-1233zd (E), boiling point 19 ° C.), may be added.

The content of the hydrofluoroolefin having a boiling point of 25 to 50 ° C. may be 5% by mass or more, preferably 7% by mass or more in the undiluted solution. The content of the hydrofluoroolefin may be 30% by mass or less, preferably 25% by mass or less, in the undiluted solution. When the content of the hydrofluoroolefin is within the above range, the particles sprayed into the space have an appropriate particle size, easily volatilize during diffusion, and the effect of reducing the number of falling particles can be easily obtained. In addition, the undiluted solution tends to have a high flash point. In particular, when the content of the hydrofluoroolefin is 7% by mass or more in the undiluted solution, the undiluted solution tends to have no flash point until it boils, and becomes a non-dangerous substance under the Fire Service Act. When the content of the hydrofluoroolefin having a boiling point of 25 to 50 ° C. is 30% by mass or less in the undiluted solution, the spray particles do not become too fine and inhalation by the user can be prevented.

In the aerosol composition of the present embodiment, it is preferable that the boiling point of the hydrofluoroolefin is lower than the flash point of the oil-based solvent. As a result, when the temperature of the undiluted solution rises, the hydrofluoroolefin begins to vaporize before reaching the flash point of the oil-based solvent. In this case, a large amount of vaporized hydrofluoroolefin is present around the stock solution. As a result, the undiluted solution is prevented from igniting and is less likely to ignite.
