Description

害虫忌避用粘着テープPest repellent adhesive tape
　本発明は害虫忌避用粘着テープに関する。特に衣服や皮膚に貼付して使用する害虫忌避用粘着テープに関する。 The present invention relates to a pest repellent adhesive tape. Particularly, the present invention relates to a pest repellent pressure-sensitive adhesive tape that is used by being attached to clothes or skin.
　近年、デング熱、チクングニア熱、ジカウイルス感染症、日本脳炎、ウエストナイル熱などの病原体を保有する蚊に刺されることによって起こる感染症（蚊媒介感染症）が、中南米やアジアなどの熱帯、亜熱帯地域で流行していることが報告されており、社会問題となっている。これらの感染症の罹らないための予防策としては、感染症の原因となる蚊に刺されないことが重要になる。 In recent years, mosquito-borne infections caused by mosquitoes carrying pathogens such as dengue fever, chikungunya fever, Zika virus infection, Japanese encephalitis, and West Nile fever have been reported in tropical and subtropical regions such as Latin America and Asia. It has been reported to be prevalent in Japan, which has become a social problem. As a preventive measure to prevent these infectious diseases, it is important not to be bitten by mosquitoes that cause the infectious diseases.
　ところで、蚊、ハエ、アブ、ダニなどの害虫を忌避する方法としては、従来より忌避剤を含有する液剤を皮膚に直接噴霧、塗布することが行われている。しかし、このような忌避剤を含有する液剤を皮膚に直接噴霧、塗布する方法は、人によっては口から吸引してむせてしまったり、或いは皮膚に炎症を起こしたりアレルギー症状などを引き起こすおそれがある。
　また、害虫を忌避する別の方法として、蚊取り線香や電気蚊取りなどが用いられている。しかし、蚊取り線香は火を使うため安全ではないし、電気蚊取りは自由に持ち運ぶことが難しいものである。 By the way, as a method of repelling harmful insects such as mosquitoes, flies, flies, and mites, a liquid agent containing a repellent has been conventionally sprayed and applied to the skin. However, the method of directly spraying and applying a liquid agent containing such a repellent to some people may inhale it by inhaling it from the mouth, or may cause skin irritation or allergic symptoms. ..
In addition, as another method of repelling harmful insects, mosquito coil and electric mosquito coil are used. However, mosquito coils are not safe because they use fire, and electric mosquito coils are difficult to carry freely.
　一方、従来より、接着剤層に忌避剤を含浸させ、衣服や皮膚へ貼付することができる害虫忌避粘着シートが知られている（特許文献１）。しかしながら、接着剤層に忌避剤を含浸させた粘着シートの場合、忌避剤と接着剤層に含まれる成分とが反応し、保存中における忌避剤含有量の安定性が低下するおそれがある。
　このため、安全で簡便に使用することができ、且つ、揮発しやすい忌避剤の保存安定性に優れ、持続的に防虫効果を有する害虫忌避用粘着テープが要望されている。 On the other hand, conventionally, a pest repellent pressure-sensitive adhesive sheet is known, which can be applied to clothes or skin by impregnating an adhesive layer with a repellent (Patent Document 1). However, in the case of a pressure-sensitive adhesive sheet in which the adhesive layer is impregnated with the repellent, the repellent and the components contained in the adhesive layer may react with each other, and the stability of the repellent content during storage may decrease.
Therefore, there is a demand for a pest repellent pressure-sensitive adhesive tape that is safe and easy to use, has excellent storage stability of a repellent that is easily volatilized, and has a persistent insect repellent effect.
実用新案登録第３１４９３８１号Utility model registration No. 3149381

When the content of the repellent is 30 to 400 g / m 2 on an area basis, the balance between the repellent volatilization rate (immediate effect of volatilization effect) and the sustainability of the volatilization effect becomes good.
　本発明における布帛とは、織布、不織布、編布などの布状のものを指し、表面に凹凸を有したものである。表面の凹凸により、布帛に含有する忌避剤の大気中への拡散性（揮散性）に優れるという効果を奏する。上記布帛のうち、不織布は繊維を熱的、機械的または化学的な作用によって接着または絡み合わせることで布にしたものであるため、ほつれなどの発生が少なく、好適に用いられる。 The cloth in the present invention refers to a cloth-like material such as woven cloth, non-woven cloth, and knitted cloth, and has unevenness on the surface. Due to the unevenness of the surface, there is an effect that the repellent contained in the fabric is excellent in diffusibility (volatility) into the atmosphere. Among the above-mentioned cloths, the non-woven cloth is a cloth formed by adhering or entwining fibers by a thermal, mechanical or chemical action, so that it is less likely to be frayed and is preferably used.
　布帛の材料としては、例えば、綿（木綿）、絹、麻、パルプ、羊毛などの天然繊維、ポリエステル（例えば、ポリエチレンテレフタレートなど）、ポリオレフィン（例えば、ポリエチレン、ポリプロピレンなど）、ポリアミド（例えば、ナイロンなど）、アクリル樹脂、ポリウレタンなどの合成繊維、アセテート繊維などの半合成繊維、レーヨン繊維、キュプラ繊維などの再生繊維などを用いることができる。上記各材料から選ばれる１種類の材料を単独で用いてもよいし、２種以上の材料を混合して用いてもよい。また、多数の繊維の集合からなる布帛においては、布帛中の全ての繊維の材質が同一でもよいし、異なる材質からなる繊維をブレンドして布帛が構成されていてもよい。布帛の材料としては、綿（木綿）、ポリエステル、ポリオレフィン、ポリアミドからなる群から選択される少なくとも１種であることが好ましい。 Examples of the material of the cloth include natural fibers such as cotton (cotton), silk, hemp, pulp and wool, polyester (eg polyethylene terephthalate), polyolefin (eg polyethylene, polypropylene etc.), polyamide (eg nylon etc.). ), Acrylic resin, synthetic fiber such as polyurethane, semi-synthetic fiber such as acetate fiber, regenerated fiber such as rayon fiber, cupra fiber and the like. One kind of material selected from the above materials may be used alone, or two or more kinds of materials may be mixed and used. Further, in a cloth composed of a large number of fibers, all fibers in the cloth may be made of the same material, or fibers made of different materials may be blended to form the cloth. The material of the cloth is preferably at least one selected from the group consisting of cotton (cotton), polyester, polyolefin and polyamide.
　本発明における布帛のかさ密度は、５０～３００ｋｇ／ｍ３であることが特徴である。かさ密度の上限は、好ましくは２８０ｋｇ／ｍ３、より好ましくは２７０ｋｇ／ｍ３であり、かさ密度の下限は、好ましくは７０ｋｇ／ｍ３、より好ましくは８０ｋｇ／ｍ３である。また、本発明における布帛の厚みは、３００～２０００μｍであることが特徴である。厚みの上限は、好ましくは１６００μｍ、より好ましくは１５００μｍであり、厚みの下限は、好ましくは４００μｍ、より好ましくは５００μｍである。なお、本発明におけるかさ密度は、布帛の坪量（ｇ／ｍ２）を厚み（μｍ）で除して算出される。
　布帛のかさ密度が５０～３００ｋｇ／ｍ３であり、且つ、布帛の厚みが３００～２０００μｍであることにより、高濃度の忌避剤を布帛に含有することが可能となり、布帛に含有する忌避剤の保存安定性（保持性）に優れるだけでなく、布帛から大気中への忌避剤の速やかな拡散性（揮散性）も得られる。 The fabric of the present invention is characterized by having a bulk density of 50 to 300 kg / m 3 . The upper limit of the bulk density is preferably 280 kg / m 3 , more preferably 270 kg / m 3 , and the lower limit of the bulk density is preferably 70 kg / m 3 , more preferably 80 kg / m 3 . The fabric of the present invention is characterized by having a thickness of 300 to 2000 μm. The upper limit of the thickness is preferably 1600 μm, more preferably 1500 μm, and the lower limit of the thickness is preferably 400 μm, more preferably 500 μm. The bulk density in the present invention is calculated by dividing the basis weight (g / m 2 ) of the cloth by the thickness (μm).
Since the bulk density of the cloth is 50 to 300 kg / m 3 and the thickness of the cloth is 300 to 2000 μm, it is possible to contain a high concentration of the repellent in the cloth, and the repellent contained in the cloth Not only is it excellent in storage stability (retention), but also rapid diffusion (volatility) of the repellent from the fabric to the atmosphere is obtained.
　布帛の坪量は、上限が好ましくは２００ｇ／ｍ２、より好ましくは１８０ｇ／ｍ２であり、下限が好ましくは７０ｇ／ｍ２、より好ましくは８０ｇ／ｍ２である。布帛を構成する繊維の直径は、上限が好ましくは２０μｍ、より好ましくは１０μｍであり、下限が好ましくは０．５μｍ、より好ましくは１μｍである。 The upper limit of the basis weight of the fabric is preferably 200 g / m 2 , more preferably 180 g / m 2 , and the lower limit is preferably 70 g / m 2 , more preferably 80 g / m 2 . The upper limit of the diameter of the fibers constituting the cloth is preferably 20 μm, more preferably 10 μm, and the lower limit thereof is preferably 0.5 μm, more preferably 1 μm.
　本発明における防御層は、忌避剤を実質的に透過しない材料からなるフィルムが好ましい。忌避剤を実質的に透過しない材料としては、例えば、ポリエステル（例えば、ポリエチレンテレフタレートなど）、ポリオレフィン（例えば、ポリエチレン、ポリプロピレンなど）、ポリアミド（例えば、ナイロンなど）、ポリ塩化ビニル、ポリ塩化ビニリデン、ポリカーボネート、ポリビニルアルコール、エチレン－酢酸ビニル共重合体などを使用することができる。中でも、ポリエステルが好ましく用いられ、ポリエチレンテレフタレートが最も好適に用いられる。上記防御層は、ポリエステル製フィルムであることが好ましく、ポリエチレンテレフタレートからなるフィルムであることがより好ましい。
　このような防御層が存在することにより布帛に含有する忌避剤が粘着剤層へ移行することを防止することができるため、布帛中の忌避剤含有量の保存安定性に寄与すると考えられる。 The protective layer in the present invention is preferably a film made of a material that is substantially impermeable to the repellent. Examples of the material that does not substantially permeate the repellent agent include polyester (eg, polyethylene terephthalate), polyolefin (eg, polyethylene, polypropylene), polyamide (eg, nylon), polyvinyl chloride, polyvinylidene chloride, polycarbonate. , Polyvinyl alcohol, ethylene-vinyl acetate copolymer and the like can be used. Among them, polyester is preferably used, and polyethylene terephthalate is most preferably used. The protective layer is preferably a polyester film, more preferably a film made of polyethylene terephthalate.
The presence of such a protective layer can prevent the repellent contained in the cloth from migrating to the pressure-sensitive adhesive layer, and is considered to contribute to the storage stability of the repellent content in the cloth.
　防御層の厚みとしては、上限が好ましくは７５μｍ、より好ましくは５０μｍであり、下限が好ましくは１２μｍ、より好ましくは２５μｍである。防御層の厚みが７５μｍを超える場合、害虫忌避用粘着テープが柔軟性に欠けるため、衣服や皮膚へ貼付した際に、衣服や皮膚の表面形状に追従しにくく貼付性に劣る可能性がある。また、防御層の厚みが１２μｍ未満の場合、忌避剤の粘着剤層への移行を防止することが困難になる。 The upper limit of the thickness of the protective layer is preferably 75 μm, more preferably 50 μm, and the lower limit is preferably 12 μm, more preferably 25 μm. When the thickness of the protective layer exceeds 75 μm, the pest repellent pressure-sensitive adhesive tape lacks flexibility, and therefore, when applied to clothes or skin, it may be difficult to follow the surface shape of the clothes or skin, resulting in poor applicability. When the thickness of the protective layer is less than 12 μm, it becomes difficult to prevent the repellent from migrating to the pressure-sensitive adhesive layer.

In the following, "parts" and "%" mean "parts by mass" and "mass%", respectively.
（製造例１～８及び比較製造例１～３）
　ポリエチレンテレフタレートフィルム（厚み：３８μｍ）の片面に、アクリル系粘着剤（イソノニルアクリレート：２－メトキシエチルアクリレート：アクリル酸＝６５部：３０部：５部からなる共重合体）の酢酸エチル溶液を、乾燥後の厚みが４０μｍとなるように塗布、乾燥して層間粘着剤層を形成した後、この層間粘着剤層に表１に示す不織布を貼り合わせて積層体を得た。次に、片面にシリコーン系樹脂による剥離処理した剥離紙（９７μｍ）に、アクリル系粘着剤（イソノニルアクリレート：２－メトキシエチルアクリレート：アクリル酸＝６５部：３０部：５部からなる共重合体）の酢酸エチル溶液を、乾燥後の厚みが４０μｍとなるように塗布、乾燥して粘着剤層を形成した後、粘着剤層の粘着面に、前述の積層体のポリエチレンテレフタレートフィルム面を貼り合わせして、不織布／層間粘着剤層／ポリエチレンテレフタレートフィルム／粘着剤層／剥離紙からなる製造例１～８及び比較製造例１～３の粘着テープを得た。 (Production Examples 1 to 8 and Comparative Production Examples 1 to 3)
On one side of a polyethylene terephthalate film (thickness: 38 μm), an ethyl acetate solution of an acrylic pressure-sensitive adhesive (isononyl acrylate: 2-methoxyethyl acrylate: acrylic acid = 65 parts: 30 parts: 5 parts copolymer), After coating so as to have a thickness after drying of 40 μm and drying to form an interlayer pressure-sensitive adhesive layer, the nonwoven fabric shown in Table 1 was attached to the interlayer pressure-sensitive adhesive layer to obtain a laminate. Next, on a release paper (97 μm) having one side subjected to a release treatment with a silicone-based resin, a copolymer composed of an acrylic adhesive (isononyl acrylate: 2-methoxyethyl acrylate: acrylic acid = 65 parts: 30 parts: 5 parts) The ethyl acetate solution of 1) is applied so that the thickness after drying is 40 μm and dried to form a pressure-sensitive adhesive layer, and then the polyethylene terephthalate film surface of the above-mentioned laminate is bonded to the pressure-sensitive adhesive surface of the pressure-sensitive adhesive layer. As a result, pressure-sensitive adhesive tapes of Production Examples 1 to 8 and Comparative Production Examples 1 to 3 composed of non-woven fabric / interlayer adhesive layer / polyethylene terephthalate film / adhesive layer / release paper were obtained.

（実施例１～１４及び比較例１～３）
　得られた粘着テープ（製造例１～８及び比較製造例１～３）を４０ｍｍφに打抜いた後、不織布面へ忌避剤（品名：ＮＲ－２０８０：理研香料社製）を表２に示す量を滴下して、実施例１～１４及び比較例１～３の害虫忌避用粘着テープを得た。 (Examples 1 to 14 and Comparative Examples 1 to 3)
The obtained adhesive tapes (Production Examples 1 to 8 and Comparative Production Examples 1 to 3) were punched out to a diameter of 40 mm, and the amount of repellent (Product name: NR-2080: manufactured by Riken Fragrance Co., Ltd.) on the non-woven fabric surface is shown in Table 2. Was dropped to obtain pest repellent adhesive tapes of Examples 1 to 14 and Comparative Examples 1 to 3.

（不織布表面上における忌避剤拡散試験）
　前述の不織布面へ忌避剤を滴下後２４時間経過した後に、不織布表面上への忌避剤の広がり具合を、ノギスを使用して縦（ｍｍ）と横（ｍｍ）の長さを測定した。測定した縦横の長さから下式により、忌避剤拡散面積を算出した。
　　　忌避剤拡散面積（ｍｍ２）＝Ｌ／２×Ｗ／２×３．１４
　　　　Ｌ：縦の長さ（ｍｍ）
　　　　Ｗ：横の長さ（ｍｍ） (Repellent diffusion test on the surface of non-woven fabric)
After the repellant was dropped on the surface of the non-woven fabric for 24 hours, the extent of the repellent on the surface of the non-woven fabric was measured with a caliper to measure the length (mm) and the width (mm). The repellent diffusion area was calculated from the measured vertical and horizontal lengths by the following formula.
Repellent diffusion area (mm 2 ) = L / 2 × W / 2 × 3.14
L: vertical length (mm)
W: Horizontal length (mm)
　忌避剤拡散面積が小さいほど、不織布中に忌避剤を良好に保持することができていると判断される。また、忌避剤拡散面積が１２５６ｍｍ２の場合、４０ｍｍφに打抜いた害虫忌避用粘着テープの全面に忌避剤が広がるため、忌避剤が粘着テープの端部をつたって粘着剤層などに移行するため好ましくないものと判断される。 It is judged that the smaller the diffusion area of the repellent, the better the retention of the repellent in the nonwoven fabric. In addition, when the repellent diffusion area is 1256 mm 2 , the repellent spreads over the entire surface of the pest repellent pressure-sensitive adhesive tape punched to 40 mmφ, and therefore the repellent moves to the pressure-sensitive adhesive layer, etc., by closing the end of the pressure-sensitive adhesive tape. It is judged to be unfavorable.
（忌避剤揮散量）
　前述の不織布面へ忌避剤を滴下後、２０±５℃の環境下に６時間保管した。忌避剤滴下直後のテープと６時間保管後のテープについて、剥離紙を剥がした後、アセトンにてテープ中に残存する忌避剤（品名：ＮＲ－２０８０：理研香料社製）を抽出した。得られた抽出液からガスクロマトグラフィーを用いて、忌避剤量をＦＩＤ検出器にて定量した。測定された忌避剤量から下式により忌避剤揮散量を算出した。
　　　忌避剤揮散量（ｍｇ）＝Ｍ０－Ｍ６
　　　　Ｍ０：滴下直後の忌避剤量（ｍｇ）
　　　　Ｍ６：６時間保管後の忌避剤量（ｍｇ） (Amount of repellent volatilized)
After the repellent was dropped onto the above-mentioned nonwoven fabric surface, it was stored in an environment of 20 ± 5 ° C. for 6 hours. After the release paper was peeled off from the tape immediately after the repellent was dropped and after the tape was stored for 6 hours, the repellent remaining in the tape (product name: NR-2080: manufactured by Riken Fragrance Co., Ltd.) was extracted with acetone. The amount of repellent from the obtained extract was quantified with an FID detector using gas chromatography. From the measured repellent amount, the repellent volatilization amount was calculated by the following formula.
Repellent volatilization amount (mg) = M 0 -M 6
M 0 : amount of repellent just after dropping (mg)
M 6 : Amount of repellent after storage for 6 hours (mg)
（忌避効果）
　忌避剤揮散量の評価において、６時間保管後の蚊に対する忌避効果を下記の基準に従い目視で判定した。
〇：十分な忌避効果あり
△：忌避効果が弱い
×：ほとんど忌避効果がない (Repellent effect)
In the evaluation of the amount of repellent volatilized, the repellent effect on mosquitoes after storage for 6 hours was visually determined according to the following criteria.
◯: Sufficient repellent effect △: Weak repellent effect ×: Almost no repellent effect

　結果を表３に示す。
　実施例１～１４の害虫忌避用粘着テープは、不織布中に忌避剤を良好に保持することができるため、粘着テープの端部をつたって忌避剤が粘着剤層などへ移行するおそれがなく、忌避剤含有量の保存安定性に優れるものであった。加えて、実施例１～１４の害虫忌避用粘着テープは、速やかに高い忌避剤揮散量を示し、良好な忌避効果を示した。
　一方、比較例１、３の害虫忌避用粘着テープは、忌避剤拡散面積が１２５６ｍｍ２であることから、忌避剤が粘着テープの端部をつたって粘着剤層などに移行するものであった。また、比較例２の害虫忌避用粘着テープは、忌避剤揮散量が低く、忌避効果として満足できるものではなかった。 The results are shown in Table 3.
Since the pest repellent pressure-sensitive adhesive tapes of Examples 1 to 14 can well retain the repellent in the nonwoven fabric, there is no fear that the repellent will migrate to the pressure-sensitive adhesive layer or the like through the ends of the pressure-sensitive adhesive tape. The storage stability of the repellent content was excellent. In addition, the pest repellent pressure-sensitive adhesive tapes of Examples 1 to 14 rapidly showed a high repellent volatilization amount and showed a good repellent effect.
On the other hand, the pest repellent pressure-sensitive adhesive tapes of Comparative Examples 1 and 3 had a repellent diffusion area of 1256 mm 2 , and therefore the repellent migrated to the pressure-sensitive adhesive layer or the like along the end of the pressure-sensitive adhesive tape. In addition, the harmful insect repellent pressure-sensitive adhesive tape of Comparative Example 2 had a low repellent volatilization amount, and was not satisfactory as a repellent effect.
