The sheet product for preventing pest invasion of the present invention and the method for preventing pest invasion using the same will be described in detail below. However, the present invention is not intended to be limited to the configurations described in the embodiments described below. In addition, when there is a notation "-" indicating a range in this specification, it includes the upper limit and the lower limit.

The present invention relates to a sheet product having a resin layer in which an ingredient for preventing insect invasion is supported on a resin, the sheet product has one surface as a chemical volatilization surface and the other surface as an adhesive surface, and conforms to JIS A 5759. Based on the above, the adhesive surface side of the sheet product is attached to a glass plate to prepare a test piece, and the outer surface of the chemical volatilization surface side is directed to the light source, and the spectral reflectance in the wavelength range of 300 to 2500 nm is measured. The sheet product for preventing pest invasion is characterized by having a solar reflectance of 15% or more when determined by .

The "solar reflectance" in the present invention is described in JIS A 5759 (2008 film for architectural window glass), and the spectral reflectance at each wavelength in the wavelength range of 300 to 2500 nm (full wavelength range) is measured, It means the reflectance calculated by taking into consideration the weighting factor and the like at each wavelength. Further, in the present invention, a test piece is prepared by attaching the sticking surface side of the pest invasion prevention sheet product to a glass plate, and the outer surface of the chemical volatilization side is directed toward the light source, and spectroscopy in the wavelength range of 300 to 2500 nm.

The sheet product for preventing pest invasion of the present invention has a solar reflectance of 15% or more, preferably 20% or more, more preferably 30% or more. Further, the sheet product may be transparent, translucent or opaque.

The pest invasion-preventing component of the present invention is not particularly limited, but includes one or more selected from the group consisting of pyrethroid compounds, diol compounds, amide compounds, and dibasic acid ester compounds.

Various compounds can be used as the pyrethroid compound, but from the point of view of the pest invasion prevention effect and usability when used, the vapor pressure at 30 ° C. is 2 × 10 ^-4 to 1 × 10 ^-2 mmHg. A range is preferably employed.
Specifically, 4-methoxymethyl-2,3,5,6-tetrafluorobenzyl 2,2-dimethyl-3-(1-propenyl)cyclopropane carboxylate (methofluthrin), 4-methyl-2,3, 5,6-tetrafluorobenzyl 2,2-dimethyl-3-(1-propenyl)cyclopropanecarboxylate (profluthrin), 2,3,5,6-tetrafluorobenzyl 2,2-dimethyl-3-(2, 2-dichlorovinyl)cyclopropanecarboxylate (transfluthrin), 4-methoxymethyl-2,3,5,6-tetrafluorobenzyl 2,2,3,3-tetramethylcyclopropanecarboxylate, 4-propargyl- 2,3,5,6-tetrafluorobenzyl 2,2,3,3-tetramethylcyclopropanecarboxylate, 1-ethynyl-2-methyl-2-pentenyl 2,2-dimethyl-3-(2-methyl- 1-propenyl)cyclopropane carboxylate (empentrin), mepafluthrin, heptafluthrin and the like, and among others, one or more selected from the group consisting of metofluthrin, transfluthrin, and profluthrin. Metofluthrin and/or transfluthrin are preferred, and more preferred. In addition, these compounds have optical isomerism based on the asymmetric carbon and geometric isomerism based on the double bond, and each and any mixture thereof are of course included in the present invention.

Examples of the diol compound include p-menthane-3,8-diol, p-menthane-1,8-diol, and 2-ethyl-1,3-hexanediol. Examples of the amide compound include 3 -(Nn-butyl-N-acetyl)aminopropionic acid ethyl ester (IR3535), deet, icaridin, etc., and the dibasic acid ester compounds include diethyl oxalate, dimethyl malonate, diethyl malonate, Dimethyl succinate, diethyl succinate, dipropyl succinate, dibutyl succinate, dimethyl glutarate, diethyl glutarate, diethyl adipate, dipropyl adipate, dibutyl adipate, diethyl sebacate, dimethyl phthalate, dibutyl phthalate, maleic acid Dibutyl and dibutyl fumarate are exemplified. Such a pest invasion-preventing component also has room-temperature volatility, and its vapor pressure at 25°C falls within the range of approximately 1×10 ⁻⁵ to 1×10 ⁻¹ mmHg.

In the present invention, α-pinene, terpineol, geraniol, linalool, citronellal, eugenol, camphor, eucalyptus, for the purpose of fragrance preparation, for example, as long as it does not interfere with the volatility performance of the pest invasion prevention ingredient and the gist of the invention. A small amount of terpene fragrances such as ptol, citral, menthol, allylheptanoate and allylhexanoate, and natural plant essential oils such as mint oil, lavender oil, orange oil, eucalyptus oil and spearmint oil may be added. do not have.

In the present invention, the resin on which the pest invasion-preventing component is supported is not particularly limited as long as it has the performance of stably and slowly releasing the pest invasion-preventing component. Examples include ethylene copolymer resin, synthetic rubber resin, polyolefin resin, One or more selected from the group consisting of polyester resins, polyamide resins, polyvinyl chloride resins, urethane resins, rosin ester resins, and paraffin wax resins can be used as appropriate.

Among them, the resin layer in which the insect pest intrusion prevention component is carried on the resin layer has a chemical permeable sheet having permeability to the insect pest invasion prevention component laminated on the chemical volatilization side of the resin layer, and the adhesive surface side of the resin layer. A lamination of drug-impermeable sheet layers that are impermeable and non-adsorbent to the pest invasion-preventing component is preferred. A hot-melt resin containing an ethylene copolymer resin and/or a synthetic rubber resin is preferable as a resin for forming such a resin layer containing a pest invasion-preventing component. The hot-melt resin is a resin that can be thermally melted and liquefied by heating, has a property of becoming solid again when cooled, and can be used as an adhesive. As the resin for adhering the two sheet layers, a hot-melt resin that does not require volatilization of the solvent is suitable because the resin carries a pest invasion-preventing component. That is, by including at least one of the ethylene copolymer resin and the synthetic rubber resin in the adhesive for fixing the pest invasion prevention component and adhering the sheet layer, the possibility of deterioration of the pest invasion prevention component is reduced. can be kept low enough. Since these resins have low reactivity with the insect pest prevention component, the hot-melt resin hardly reacts with the insect pest prevention component even when mixed, and the pest prevention component can be preserved for a long period of time.

Here, the ethylene copolymer resin means a copolymer resin of ethylene and another monomer having a reactive group such as a vinyl group or a vinylidene group that undergoes a copolymerization reaction with ethylene, and is an ethylene-vinyl acetate copolymer resin. , ethylene-(meth)acrylic acid copolymer resin, ethylene-methyl (meth)acrylate copolymer resin (that is, ethylene-methyl (meth)acrylate copolymer resin), ethylene-ethyl (meth)acrylate copolymer resin, etc. is mentioned. In addition, "(meth)acryl" means "acryl" or "methacryl". Among them, it is preferable to include ethylene-vinyl acetate copolymer resin or ethylene-methyl methacrylate copolymer resin in the resin in an amount of 30% by mass or more because the above-mentioned effects are preferably exhibited. The pest invasion-preventing component, which is retained while suppressing deterioration, can be released gradually while being controlled by the content in the resin layer and the permeability of the drug-permeable sheet. Further, when ethylene-vinyl acetate copolymer resin or ethylene-methyl methacrylate copolymer resin is contained in the resin in an amount of 30% by mass or more, the reaction with the pest invasion-preventing component is reduced, which is preferable, and is preferably 40% by mass in the resin. It is more preferable to contain the above, and it is more preferable that the ethylene-vinyl acetate copolymer resin or the ethylene-methyl methacrylate copolymer resin accounts for the entirety of the resin. In the ethylene copolymer resin, the molar ratio between the ethylene monomer component and other monomer components such as vinyl acetate (monomer) and methyl methacrylate (monomer) is 5:95 to 95:5. preferable. Outside this range, the properties of the homopolymer rather than the ethylene copolymer resin become too strong, and the effects of the invention may not be exhibited.

On the other hand, the synthetic rubber resin includes styrene-butadiene-styrene (hereinafter abbreviated as "SBS") block copolymer, styrene-isoprene-styrene block copolymer, and styrene-ethylene-butene-styrene block copolymer. , and styrene-ethylene-propylene-styrene block copolymers. When the proportion of the synthetic rubber resin increases, blocking tends to occur in the cross section of the laminated sheet. Therefore, it is preferable to use the synthetic rubber resin together with the ethylene copolymer resin to suppress blocking rather than using the synthetic rubber resin alone.

The hot melt resin may contain polyolefin resin, polyester resin, polyamide resin, rosin ester resin, and paraffin wax resin as other components in addition to the ethylene copolymer resin and the synthetic rubber resin. However, the compatibility with the insect pest invasion prevention component in the heat melting process, the temperature stability of the insect pest invasion prevention component and the adhesive itself, and the adhesive strength must be suitable.

The softening point of the hot-melt resin is preferably 70° C. or higher. When the softening point is within the above range, even when stored in a high-temperature environment, the possibility of blocking, delamination, bleeding out of the resin from the cross section of the laminated sheet, etc., is reduced. On the other hand, it is preferable that the softening point is 180° C. or lower. When the softening point is within the above range, when the resin layer is liquefied by heat melting, there is less possibility that the insect pest invasion-preventing component will react and the efficacy will be lost. . The softening point is determined by the ring and ball method.

The blending mass ratio of the pest invasion-preventing component forming the resin layer and the resin is preferably 5:95 to 50:50, more preferably 5:95 to 30:70, and 10:90. ~20:80 is more preferred. Within the above range, the effect of preventing invasion of pests, adhesive strength, and weather resistance to light and the like are excellent.

Although the thickness of the resin layer is not particularly limited, it is preferably 40 to 400 μm, more preferably 50 to 200 μm, even more preferably 60 to 150 μm. Within the above range, the insect pest intrusion prevention effect and weather resistance such as light are excellent.

Furthermore, in addition to the pest invasion-preventing component and the resin, other various components may be added to the resin layer as long as they do not degrade the pest invasion-preventing component and do not significantly hinder volatilization. . Examples thereof include ultraviolet absorbers, ultraviolet scattering agents, brighteners, dispersants, fragrances, pigments, and dyes. These components are preferably mixed when preparing the heat-melted and liquefied mixture.

Examples of the pigment or dye include, but are not particularly limited to, white, blue, red, yellow, green, and other pigments or dyes. Examples of white pigments or dyes include titanium CR97, which is titanium oxide. Examples of blue pigments or dyes include Dipyroxide Color Blue 9453 (manufactured by Dainichiseika Kogyo Co., Ltd.), Fastogen Blue 5485 (manufactured by Dainippon Ink and Chemicals), Fastogen Blue RS (manufactured by Dainippon Ink and Chemicals), and cyanine. Blue 5240KB (manufactured by Dainichiseika Kogyo Co., Ltd.), SUMIPLAST BLUE OA (manufactured by Sumika Chemtex Co., Ltd.), and the like. Examples of red pigments or dyes include Todacolor 120ED (manufactured by Toda Kogyo Co., Ltd.), Fastogen Super Magenta RH (manufactured by Dainippon Ink and Chemicals), Fastogen Red 7100Y (manufactured by Dainippon Ink and Chemicals), and Rubicron Red 400RG (manufactured by Dainippon Ink and Chemicals). manufactured by Nippon Ink Chemical Industry Co., Ltd.) and the like. Examples of yellow pigments or dyes include Symuler Fast Yellow 4192 (manufactured by Dainippon Ink and Chemicals) and Sycopearl Yellow L-1110 (manufactured by BASF). Examples of green pigments or dyes include Dipyroxide Color Green 9310 (manufactured by Dainichiseika Kogyo Co., Ltd.), First Gen Green 2YK (manufactured by Dainippon Ink and Chemicals), and Lionol Green 6YKP-N (manufactured by Toyo Ink Mfg. Co., Ltd.). etc. In this case, the content of the pigment or dye is not particularly limited, but is preferably 0.005 to 5% by weight relative to the insect pest invasion-preventing component.

The color of the chemical volatilization side of the sheet product of the present invention is not particularly limited. , yellow (including deep yellow, yellow, pale yellow, etc.), red (including deep red, red, pale red, pink, etc.), and white. Among these, blue (including dark blue, blue, light blue, light blue, etc.), green (including dark green, green, light green, etc.), white are preferable, and blue (blue, dark blue, light blue, light blue, etc.) (including pale blue, etc.), or white is more preferable. Note that each color in this specification conforms to JIS Z 8102 (2001 Color names of object colors).

Next, each sheet layer constituting the laminated type sheet product for preventing invasion of pests will be described. The resin layer in which the insect pest invasion preventing component is supported on the resin has a chemical permeable sheet having permeability to the insect pest invasion preventing component laminated on the chemical volatilization surface side, or the chemical vaporization preventing component is laminated on the chemical volatilization surface side. A drug-permeable sheet permeable to a pest invasion-preventing component is laminated, and a drug-impermeable sheet layer impermeable to and non-adsorbing to the pest invasion-preventing component is laminated on the sticking surface side. and so on.
Among them, the resin layer in which the insect pest invasion prevention component is supported on the resin is laminated with a chemical permeable sheet permeable to the insect invasion prevention component on the chemical volatilization side, and on the adhesive surface side. A lamination of drug-impermeable sheet layers that are impermeable and non-adsorbent to the pest invasion-preventing component is preferred.

As the drug-impermeable sheet layer, a sheet layer that is impermeable and non-adsorbent to the pest invasion-preventing component is used. This is because when volatilizing the pest invasion-preventing component from the drug-permeable sheet layer, it is more useful to prevent volatilization from the drug-impermeable sheet layer on the opposite side. In addition, impermeability includes not only those that completely prevent permeation but also those that do not permeate, even if slightly, to the extent that the pest invasion-preventing component exerts its efficacy.

Examples of the drug-impermeable sheet layer include polyester sheets such as polyethylene terephthalate and polybutylene terephthalate, and sheets made of acrylonitrile, aluminum foil, polyamide, and the like.

The thickness of the drug impermeable sheet layer is preferably 5 μm or more, more preferably 10 μm or more, and even more preferably 20 μm or more. Within the above range, there is no risk of permeation of the pest invasion-preventing component even with the above material, and the lack of strength causes scratches, and the pest invasion-preventing component volatilizes from the scratches. possibility becomes negligible. On the other hand, the greater the thickness, the lower the permeability, so there is no particular upper limit from the viewpoint of permeability, but from the viewpoint of being able to suitably adjust the weight and rigidity, the thickness is preferably 150 μm or less, more preferably 100 μm or less. It is preferably 70 μm or less, and more preferably 70 μm or less.

As the drug-permeable sheet layer, a sheet layer having permeability to the pest invasion-preventing component is used. Polyolefin resins such as polyethylene and polypropylene; biodegradable resins such as polylactic acid; are exemplified. Among these, polyolefin-based resins are preferable because they can effectively permeate and permeate the insect pest prevention component.

By changing the thickness of the drug-permeable sheet layer, it is possible to control the permeation and permeation speed of the insect pest invasion-preventing component. Depending on the content of the insect pest invasion-preventing component, in most cases the thickness is preferably 5 to 150 μm, more preferably 10 to 100 μm, and even more preferably 20 to 70 μm. By being within the above range, the possibility of deformation or tearing when coating the heat-melted mixture, or the possibility of pinhole opening or tearing during storage and use is negligible, Also, the transparency is not impaired and the rigidity is not excessively increased.

When polyolefin is used for these drug-permeable sheet layers and, for example, profluthrin or empentrin is used as the pest-infestation-preventing component, it is particularly preferable because the period of use can be set for about 1 to 4 months. Examples of the polyolefin sheet include a polyethylene film and a polypropylene film. These pyrethroid compounds permeate and permeate the drug-permeable sheet layer and volatilize from the surface.

In addition, in order to appropriately change the volatility of the drug-permeable sheet layer, a perforated sheet in which holes are artificially made through the front and back surfaces can be used. The diameter of this hole can be adjusted as appropriate, and should be adjusted between about 100 and 500 μm. In the case of such a perforated film, even if the resin itself constituting the drug-permeable sheet is drug-impermeable, the pest invasion-preventing component can permeate through the holes, so that the range of material selection is increased. spread. However, the use of perforated polyolefin-based sheets, in which the resin itself is permeable, is easier to adjust and easier to use. Furthermore, various nonwoven fabrics can be used as the drug-permeable sheet layer. Examples of materials for such nonwoven fabrics include polyethylene fibers, polypropylene fibers, polyethylene terephthalate fibers, and mixed paper products thereof. In the case of such a non-woven fabric, the non-woven fabric itself, which is made into a cloth by entangling the fibers, is opaque white due to its structural characteristics. When the non-woven fabric contains no dye or pigment, the color of the chemical volatilization side of the sheet product is white.

A combination of using the perforated sheet and/or nonwoven fabric as the drug-permeable sheet layer and using, for example, metofluthrin or transfluthrin is also suitable for setting a period of use of about 1 to 4 months. . In addition to penetrating and permeating through the film, these drugs volatilize from the pores or the interstices of the nonwoven fabric to ensure sufficient sustained release.

As a method for forming the sheet product for preventing pest invasion according to the present invention from the resin layer and each of the sheet layers, one of the sheet layers is coated with the resin mixture that has been melted and liquefied by heat. , before the mixture hardens, the other sheet layer is laminated, or one of the sheet layers is coated with the heat-melted and liquefied resin mixture, and after the resin hardens, the other sheet layer is laminated. A general method such as allowing the The first sheet layer to be coated may be either the drug-impermeable sheet layer or the drug-permeable sheet layer, but the drug-impermeable sheet layer is preferred because wrinkles are less likely to occur.

The size of the thus-prepared pest invasion-preventing sheet product of the present invention can be appropriately selected for use. .

In the sheet product for preventing pest invasion of the present invention, a pressure-sensitive adhesive layer made of a pressure-sensitive adhesive is provided on the surface of the drug-impermeable sheet layer opposite to the resin layer, and the pressure-sensitive adhesive can be peeled off thereon. It is possible to adopt an embodiment in which a separator is adhered. (That is, the drug-impermeable sheet layer is laminated between a resin layer and an adhesive layer, and a separator that can be peeled off from the adhesive is adhered onto the adhesive layer.) In the case of the embodiment, the pest invasion-preventing sheet product can be adhered to the outer surface of various window glass or the like by peeling off the separator and using the adhesive effect of the pressure-sensitive adhesive layer.

Examples of adhesives used for these include various adhesives such as rubber-based adhesives, acrylic adhesives, and silicone-based adhesives, but are not particularly limited to these. However, these pressure-sensitive adhesives need to be those that do not deteriorate even when the insect pest invasion-preventing component is adsorbed. It is also possible to use a double-sided adhesive tape instead of the adhesive. As for the separator, various separators such as those made of paper or film are exemplified as general separators, but are not particularly limited to these.
Further, the pressure-sensitive adhesive layer may also contain other components in the same manner as the resin layer. Examples thereof include ultraviolet absorbers, ultraviolet scattering agents, brighteners, dispersants, fragrances, pigments, and dyes.

In the present invention, the pest invasion prevention sheet product of the present invention is installed on the outer surface of the window glass of a building such as a store or a house, and the pest invasion prevention sheet product contains 1 to 400 mg/day/m ² , preferably 2 to 400 mg/day/m 2 . It is characterized by volatilizing the insect pest invasion prevention component at a rate of 200 mg/day/m ² and preventing the invasion of pests into buildings such as shops and houses for about 1 to 4 months. Here, as an installation method, it is used by adhering using the above-described adhesive layer.

When storing the pest invasion-preventing sheet product of the present invention, the perimeter of the sheet product is wrapped and sealed to saturate the vapor of the pest invasion-preventing component in the sealed container, thereby preventing further volatilization from the resin layer. can be prevented. Then, it may be opened at the time of use, and applied to the outer surface of the window glass of a building such as a store or a house.

The place of use of the pest invasion-preventing sheet product of the present invention is not particularly limited as long as it can achieve the purpose of preventing pests such as flying pests and creeping pests from entering buildings such as shops and houses. , doors of stores such as convenience stores, restaurants, supermarkets, automatic doors, glass doors, glass automatic doors, window glass, noren, etc., but since they are inconspicuous and have excellent light stability, glass It is suitable for use on exterior surfaces such as doors, automatic glass doors, and window panes.
