It should be noted that Japanese Patent No. 5053114 (Patent Document 7) discloses a repellent silicone rubber composition in which bifluthrin is mixed with an oxime-type liquid silicone rubber composition that is a condensation type. , but because the condensation type cannot avoid the formation of by-products, and bifenthrin is non-volatile and has completely different properties from flying pest repellent fragrance ingredients, so it cannot be used as a reference

preparation example Construction

[0078] Examples of solvents used in the preparation of flying pest repellent products include lower alcohols such as water, ethanol, and isopropanol; ketone-based solvents, ester-based solvents, and hydrocarbon-based solvents such as normal alkanes and isoalkanes. These solvents may be used alone or in any combination. Surfactants include, for example, polyoxyethylene hydrogenated castor oil, polyoxyethylene higher alkyl ethers (polyoxyethylene lauryl ether, polyoxyethylene oleyl ether, etc.), polyoxyethylene alkylphenyl ethers, polyoxyethylene Higher fatty acid esters, polyoxyethylene sorbitan fatty acid esters, polyoxyethylene fatty acid glycerides, polyoxyethylene polyoxypropylene alkyl ethers and other non-ionic surfactants; laurylamine oxide, stearylamine oxide , lauryl amidopropyl dimethylamine oxide and other advanced alkylamine oxide-based surfactants, etc. These surfactants may be used alone or in any combination.

[0096] As a two-component addition type liquid silicone rubber composition, silicone rubber composition 1 and 2 were prepared according to the following recipe, the prepared silicone rubber composition 1 and 2 were mixed at room temperature, and the injection molding machine was used to It is cured at 140°C and formed into a rope ring imitating animal characters (wire diameter: about 2mm, weight: 1.6g, hardness: 32 degrees). After molding, it was placed in an oven, and post-cured at 210° C. for 5 hours to obtain a silicone rubber molded body.

[0124] Except that the components (A) and (D) of the addition-type liquid silicone rubber composition were changed to the compositions shown in Table 1, according to Example 1, the cured product of the addition-type liquid silicone rubber composition was molded into a rope shape The rubber molded body was made to absorb the flying pest repelling fragrance composition of the composition shown in Table 2 to obtain the flying pest repelling product of the present invention (Examples 2-10). It should be noted that in Table 1, "A-1" refers to dimethyl polysiloxane whose ends of the molecular chain are terminated by dimethylvinylsiloxane groups, and "A-2" refers to the two ends of the molecular chain Methyl vinyl polysiloxane terminated by trimethylsiloxy group, "A-3" is methyl vinyl polysiloxane terminated by dimethyl vinyl siloxane at both ends of the molecular chain. In addition, "siloxane-modified silica P" is siloxane-modified silica surface-treated with HMDS, and "siloxane-mod...

Abstract

Provided is a flying-noxious-insect-repellent product in which a silicone rubber has improved molding workability, mechanical properties, etc. The flying-noxious-insect-repellent product also has excellent ability to volatilize flying-noxious-insect-repellent fragrance components and excellent flying-noxious-insect-repelling effects. A flying-noxious-insect-repellent product that comprises a silicone rubber molded body that has a hardness of no more than 50 degrees and a flying-noxious-insect-repellent fragrance composition that is retained in the silicone rubber molded body. The silicone rubber molded body is a cured product of an addition-type liquid silicone rubber composition. The flying-noxious-insect-repellent fragrance composition contains, as flying-noxious-insect-repellent fragrance components, (a) a terpene hydrocarbon compound and/or a terpene ketone compound, (b) an ester compound, and (c) a terpene alcohol compound, the ratio {(X+Y)/Z} of the total of the amount X of (a) and the amount Y of (b) to the amount Z of (c) being 0.2-4.0.

Description

technical field [0001] The present invention relates to maintaining a flying pest repelling fragrance composition containing a flying pest repelling fragrance component in a silicone rubber molded body with a hardness of 50 degrees or less in a state of entering gaps in the molecular structure of rubber constituting the silicone rubber molded body A flying pest repelling product and a flying pest repelling method using the flying pest repelling product. Background technique [0002] Conventionally, a method of applying a repellent containing DEET (N,N-diethyltoluamide) to the skin surface has been widely used against flying pests such as mosquitoes, gnats, midges, and flies. However, since DEET has slightly lower volatility than general fragrance ingredients, it cannot expect a spatial repellent effect. On the other hand, although normal temperature volatile insecticidal ingredients, such as pyrethroid-based ethynethrin, etc., can be dispersed in the space to achieve the re...
