Description
【０００１】
【発明の属する技術分野】
この発明は、ガラス窓、ショーウィンド、壁面等に塗布して用いる透明性害虫防除剤に関する。
【０００２】
【従来の技術】
一般に、可視光や紫外線などの光に集まる習性のある昆虫として、ユスリカ、チョウバエ、コバエ、キノコバエ、クモ、カメムシなど数多くのものが知られている。このような昆虫は、ヒトに直接に害を及ぼすものばかりでなく、食品などを販売する店舗やドライブインその他の外食産業の店舗の窓ガラスにとまって、店舗利用客に嫌悪感を与える不都合があるものもあり、場合に応じて駆除することが要望される。
【０００３】
従来、ガラス窓、ショーウィンド、壁面等にとまっているこのような害虫を駆除するには、周知の汎用殺虫剤を直接噴霧する場合が多いが、そのような汎用殺虫剤を予め要所に塗布しておくことも考えられる。
【０００４】
【発明が解決しようとする課題】
しかし、ガラス面などの透明な面に汎用の殺虫剤を付着させると、塗布面が半透明になり、汚れたように見えるという問題点がある。
【０００５】
このように殺虫剤の塗布面が汚れて見える原因としては、▲１▼付着した殺虫剤が不均一に乾燥するので、被膜の表面に凹凸が形成されて半透明になること、▲２▼溶媒の蒸発に伴って高濃度になった有効成分等が析出するかまたは油滴を形成すること、▲３▼殺虫剤が乾燥するまでに空気中の塵埃が付着することが考えられる。
【０００６】
また、屋外のガラス面や壁面などに塗布された殺虫剤は、できるだけ長期間にわたって防除効果を発揮することが好ましく、そのために直射日光や雨水（流水）などに耐える耐候性も要求される。
【０００７】
そこで、この発明の課題は、上記した問題点を解決して、透明性の害虫防除剤を駆除面にムラなく塗布でき、乾燥した際には析出等がなくて透明性を維持できるものとし、かつ塗膜に塵埃が付着し難いものとして、害虫防除性の被膜の透明性を長期間保つことができ、しかも害虫防除性に耐候性があるものとすることである。
【０００８】
【課題を解決するための手段】
上記した課題を解決するため、この発明においては、害虫防除有効成分と、この害虫防除有効成分を溶解可能な透明性有機化合物からなる被膜形成成分と、２０℃の飽和蒸気圧が１２００〜１５００Ｐａの有機溶剤とを含有してなる透明性害虫防除剤としたのである。
【０００９】
または、害虫防除有効成分５．０重量％以下と、前記害虫防除有効成分を溶解可能な透明性有機化合物からなる被膜形成成分０．１〜１０重量％とを含有し、残部が２０℃の飽和蒸気圧１２００〜１５００Ｐａの有機溶剤からなる透明性害虫防除剤としたのである。
【００１０】
また、前記の透明性害虫防除剤における害虫防除有効成分として、ジクロルボス、ＥＺ−エンペントリン、フェンバレレート、シフェノトリン、シペルメトリン、デカメスリン、カデスリン、ペルメトリン、フェノトリン、プロパルスリン、レスメトリン、シフルスリン、トラロメトリン、フルシトリネート、フェンプロパトリン、ビフェントリン、シラフルオフェン、エトフェンプロックス、プロポクスルおよびフェノブカルブからなる群から選ばれる一種以上の殺虫成分を採用したのである。
【００１１】
または、前記の透明性害虫防除剤における害虫防除有効成分として、ジエチルトルアミド、シペラスオイル、コハク酸ジ−ｎ−ブチル、ジ−ｎ−プロピルイソシンコメロネート、および２，３，４，５−ビス（Δ2 ブチレン）テトラヒドロフルフラールからなる群から選ばれる一種以上の害虫忌避成分を採用したのである。
【００１２】
また、前記の透明性害虫防除剤における被膜形成成分として、炭素数１０〜１４のアルキル基を有するアルキルベンゼンまたはその誘導体、リン酸トリブチル、フタル酸ジメチル、オレイン酸ブチル、ジエチレングリコールジベンゾエートおよびアセチルリシノール酸メチルからなる群から選ばれる遅乾燥性の透明性有機化合物を採用したのである。
【００１３】
この発明の透明性害虫防除剤は、害虫防除有効成分と、これを溶解した被膜形成成分と、所定の乾燥速度で乾燥する有機溶剤（２０℃の飽和蒸気圧が１２００〜１５００Ｐａ）とからなるので、ガラス面などの表面に２０ミリリットル／ｍ2 塗布された際に、２０℃の室内で３〜１０分以内に乾燥し、均等な膜厚の乾燥被膜を形成する。
【００１４】
有機溶剤が上記乾燥速度の範囲内であれば、通常の薬剤噴霧による塗布作業中に先に塗布した部分が、表面張力（濡れ性）および重力によって、膜厚が一定になる以前に乾燥することがなく、しかも乾燥完了までに塵埃が付着し難く、処理面が透明（クリヤー）に仕上がる。
【００１５】
【発明の実施の形態】
この発明の透明性害虫防除剤に用いる害虫防除有効成分は、可視光や紫外線などの光に集まる習性のある昆虫として、ユスリカ、チョウバエ、コバエ、キノコバエ、クモ、カメムシなど数多くのものに対して有効なものが好ましく、また害虫防除剤のガラス面などに対する通常の塗布量が、約２０ミリリットル／ｍ2 であるため、０．１ｇ／ｍ2 以下で有効なものが適当である。このような点で好ましい殺虫性の害虫防除有効成分としては、ジクロルボス、ＥＺ−エンペントリン、フェンバレレート、シフェノトリン、シペルメトリン、デカメスリン、カデスリン、ペルメトリン、フェノトリン、プロパルスリン、レスメトリン、シフルスリン、トラロメトリン、フルシトリネート、フェンプロパトリン、ビフェントリン、シラフルオフェン、エトフェンプロックス、プロポクスルまたはフェノブカルブが挙げられる。
【００１６】
または、害虫忌避性のある害虫防除有効成分としては、ジエチルトルアミド、シペラスオイル、コハク酸ジ−ｎ−ブチル、ジ−ｎ−プロピルイソシンコメロネートまたは２，３，４，５−ビス（Δ2 ブチレン）テトラヒドロフルフラールが挙げられる。
【００１７】
上述の害虫防除有効成分は、適宜に２種以上を混合して用いてもよいのは勿論である。そして、このような害虫防除有効成分は、透明性害虫防除剤中に５．０重量％以下の割合で配合する。この配合量は、駆除対象の害虫に薬効を及ぼすことのできる量を特定することが困難であるため、下限値を特に限定できないが、低濃度で薬効が及ぶような微小な害虫を駆除対象にする場合には、０重量％を越えて微量でも添加されていればよい。そして、５．０重量％を越えて配合した場合には、乾燥した害虫防除剤の被膜に曇りが生じ易くなり、害虫防除剤に所要のクリヤーな透明性膜が得られないので好ましくない。
【００１８】
また、この発明に用いる被膜形成成分は、上記の害虫防除有効成分を溶解可能であり、かつ前記した有機溶媒に相溶性のある透明性有機化合物からなり、乾燥速度は前記の有機溶媒に比較して遅いものを採用する。前記害虫防除有効成分および前記有機溶媒の両者に対して溶解しない被膜形成成分であれば、害虫防除剤の乾燥後に、有効成分が微小な結晶や油滴となって、被膜が曇る原因になるからである。
【００１９】
このような被膜形成成分として採用できる遅乾燥性は、例えば試料５ｇを直径８０ｍｍの皿に入れて、ケット赤外線水分計で試料の５０％が減量する温度を測定した場合に、６０〜１２０℃の範囲にあることにより確認できる物性である。
【００２０】
そのような条件を満足する被膜形成成分の化合物名を例示すると、炭素数１０〜１４のアルキル基を有するアルキルベンゼンまたはその誘導体、リン酸トリブチル、フタル酸ジメチル、オレイン酸ブチル、ジエチレングリコールジベンゾエートおよびアセチルリシノール酸メチルなどである。
【００２１】
このような被膜形成成分の配合割合は、０．１〜１０重量％であることが好ましい。なぜなら、所定重量％未満の配合量では、被膜形成後に油性の有効成分が油滴となったり、結晶性有効成分が析出することによる白濁化が起こり易くなり好ましくなく、所定重量％を越える配合量では、乾燥時間が１０分を越える長時間となって塵埃の付着量が増加して好ましくないからである。
【００２２】
この発明に用いる有機溶剤は、２０℃の飽和蒸気圧が１２００〜１５００Ｐａの有機溶剤である。前記乾燥速度を越える速乾性の有機溶剤（２０℃の飽和蒸気圧が１５００Ｐａを越えるもの）では、塗布作業中に特定粘度の液状の透明性害虫防除剤が、塗布後に膜厚が一定になる前に乾燥し始めるため、塗膜厚が均一に形成されず、肉眼で判別可能なムラが生じる。また、所定乾燥速度未満（２０℃の飽和蒸気圧が１２００Ｐａ未満）の有機溶剤を使用すると、屋外で乾燥する塗膜である場合に、乾燥完了までに塵埃が付着し易く、処理面が透明（クリヤー）に仕上がらない。
【００２３】
このような所定の乾燥性の有機溶剤の具体例としては、イソパラフィン、ｎ−パラフィンなどの一般式Ｃn Ｈ2n+2のパラフィン系炭化水素（＝脂肪族飽和炭化水素）であり、炭素数ｎ＝８〜１６、好ましくは９〜１０のものである。
【００２４】
上記した原材料を一括混合して製造できるこの発明の透明性害虫駆除剤は、対象害虫が飛来するガラス面等の屋外側に塗布して用いるが、前処理として塗布面の汚れを充分に取り除いておくことが好ましい。そのような汚れが、塗布後のムラや曇りの原因になるからである。
【００２５】
塗布方法としては、刷毛塗りやローラー塗りでは、ムラが生じ易いので、確実に透明な被膜を形成するためには、噴霧塗装することが好ましい。使用する噴霧器は、トリガー（引き金）付きのスプレーガンを用いることが好ましく、ガラス面等から２０〜３０ｃｍ離れた位置から塗布面の全面が濡れるように均等に吹き付ける。このようにすると、約２０ミリリットル／ｍ2 の塗布量で液垂れがなく、均等な膜厚に塗布できる。
【００２６】
このような被膜は、塗布後に拭き取らずにそのまま２〜３分程度乾燥させると均一な被膜が形成される。
【００２７】
なお、上記の透明性害虫防除剤は、ガラス面塗布用の透明性害虫防除剤、特に透明なガラス面塗布用透明性害虫防除剤の用途に適用できることは勿論であり、さらに撥水剤、紫外線吸収剤、酸化防止剤、香料などの周知の添加剤を配合してもよく、半透明の被膜を形成する場合には顔料などを添加することもできる。

BACKGROUND OF THE INVENTION
The present invention relates to a transparent pest control agent used by applying to glass windows, show windows, wall surfaces and the like.
[0002]
[Prior art]
In general, many insects such as chironomids, butterflies, fly flies, mushrooms, spiders and stink bugs are known as insects having habits of gathering in light such as visible light and ultraviolet light. Such insects are not only harmful to humans, but also have the inconvenience of being disgusted by store customers who are stuck in the window glass of stores that sell foods, drive-in and other restaurants. There are some, and it is desired to disinfect them when necessary.
[0003]
Conventionally, well-known general insecticides are often sprayed directly in order to control such insects on glass windows, show windows, wall surfaces, etc. It is also possible to keep it.
[0004]
[Problems to be solved by the invention]
However, when a general-purpose insecticide is attached to a transparent surface such as a glass surface, there is a problem that the coated surface becomes translucent and looks dirty.
[0005]
The reason why the coated surface of the insecticide appears to be dirty is as follows. (1) The attached insecticide dries out unevenly, so that irregularities are formed on the surface of the coating and become translucent. (2) Solvent It is conceivable that the active ingredient or the like having a high concentration as a result of evaporation of the liquid deposits or forms oil droplets, and (3) dust in the air adheres until the insecticide dries.
[0006]
Moreover, it is preferable that the insecticide applied to an outdoor glass surface or wall surface exhibits a control effect for as long as possible, and for that purpose, weather resistance that is resistant to direct sunlight, rainwater (running water), and the like is also required.
[0007]
Therefore, the object of the present invention is to solve the above-mentioned problems, and to apply a transparent pest control agent evenly on the control surface, and to maintain transparency without precipitation when dried, In addition, it is intended that the pest control film can be kept transparent for a long period of time, and that the pest control property is weather resistant, as it is difficult for dust to adhere to the coating film.
[0008]
[Means for Solving the Problems]
In order to solve the above-described problems, in the present invention, a pest control active ingredient, a film forming component made of a transparent organic compound capable of dissolving this pest control active ingredient, and a saturated vapor pressure at 20 ° C. of 1200 to 1500 Pa. It was a transparent pest control agent containing an organic solvent.
[0009]
Alternatively, it contains 5.0% by weight or less of a pest control active ingredient, and 0.1 to 10% by weight of a film-forming component made of a transparent organic compound capable of dissolving the pest control active ingredient, and the remainder is saturated at 20 ° C. A transparent pest control agent comprising an organic solvent having a vapor pressure of 1200 to 1500 Pa was used.
[0010]
In addition, as a pest control active ingredient in the above-mentioned transparent pest control agent, dichlorvos, EZ-empentrin, fenvalerate, ciphenothrin, cypermethrin, decameslin, kadeslin, permethrin, phenothrin, propulserin, resmethrin, cyfluthrin, tralomethrin, full One or more insecticidal components selected from the group consisting of citrinate, phenpropatoline, bifenthrin, silafluophene, etofenprox, propoxl and fenobucarb were employed.
[0011]
Alternatively, as a pest control active ingredient in the transparent pest control agent, diethyltoluamide, cyperus oil, di-n-butyl succinate, di-n-propylisocincomeronate, and 2,3,4,5- it had adopted a bis (delta 2-butylene) one or more pest repellent component selected from the group consisting of tetrahydrofurfuryl.
[0012]
Further, as a film forming component in the transparent pest control agent, alkylbenzene having an alkyl group having 10 to 14 carbon atoms or a derivative thereof, tributyl phosphate, dimethyl phthalate, butyl oleate, diethylene glycol dibenzoate and methyl acetylricinoleate A slow-drying transparent organic compound selected from the group consisting of:
[0013]
The transparent pest control agent of the present invention comprises a pest control active ingredient, a film-forming component in which the pest control ingredient is dissolved, and an organic solvent (saturated vapor pressure at 20 ° C. is 1200 to 1500 Pa) that is dried at a predetermined drying speed. When applied to a surface such as a glass surface at a rate of 20 ml / m 2, it is dried in a room at 20 ° C. within 3 to 10 minutes to form a dry film having a uniform film thickness.
[0014]
If the organic solvent is within the range of the above drying speed, the part previously applied during normal drug spraying operation should be dried before the film thickness becomes constant due to surface tension (wetting) and gravity. In addition, it is difficult for dust to adhere by the completion of drying, and the treated surface is transparent (clear).
[0015]
DETAILED DESCRIPTION OF THE INVENTION
The pest control active ingredient used in the transparent pest control agent of this invention is effective against many things such as chironomids, butterflies, fly flies, mushrooms, spiders, stink bugs, etc. as habitual insects that gather in light such as visible light and ultraviolet light In addition, since the usual coating amount of the pest control agent on the glass surface or the like is about 20 ml / m 2 , those effective at 0.1 g / m 2 or less are suitable. Preferable insecticidal pest control active ingredients in this respect include dichlorvos, EZ-empentrin, fenvalerate, ciphenothrin, cypermethrin, decameslin, cadhesrin, permethrin, phenothrin, propulserin, resmethrin, cyfluthrin, tralomethrin, full Citrinate, phenpropatoline, bifenthrin, silafluophene, etofenprox, propoxl or fenobucarb.
[0016]
Alternatively, the pest repellent active ingredient having pest repellent includes diethyltoluamide, cyperus oil, di-n-butyl succinate, di-n-propylisocincomellonate or 2,3,4,5-bis (Δ 2 Butylene) tetrahydrofurfural.
[0017]
Of course, two or more kinds of the above-mentioned pest control active ingredients may be appropriately mixed and used. And such a pest control active ingredient is mix | blended in the ratio of 5.0 weight% or less in a transparent pest control agent. This compounding amount is difficult to specify the amount that can have a medicinal effect on the pests to be controlled, so the lower limit value can not be specifically limited, but the minute pests that have a medicinal effect at low concentrations are targeted for control. In that case, it may be added in a minute amount exceeding 0% by weight. If the blending amount exceeds 5.0% by weight, the dried pest control film tends to be cloudy, and the clear transparent film required for the pest control agent cannot be obtained.
[0018]
The film-forming component used in the present invention is composed of a transparent organic compound that can dissolve the above-mentioned pest control active ingredient and is compatible with the above-mentioned organic solvent, and has a drying rate compared to the above-mentioned organic solvent. Adopt a slow one. If it is a film-forming component that is insoluble in both the pest control active ingredient and the organic solvent, the active ingredient becomes fine crystals and oil droplets after drying the pest control agent, causing the film to become cloudy. It is.
[0019]
The slow drying property that can be employed as such a film-forming component is, for example, when 5 g of a sample is put in a plate having a diameter of 80 mm and the temperature at which 50% of the sample is reduced is measured with a ket infrared moisture meter, the temperature is 60 to 120 ° C It is a physical property that can be confirmed by being in the range.
[0020]
Examples of the compound name of the film forming component satisfying such conditions include alkylbenzene having an alkyl group having 10 to 14 carbon atoms or a derivative thereof, tributyl phosphate, dimethyl phthalate, butyl oleate, diethylene glycol dibenzoate and acetylricinol Such as methyl acid.
[0021]
The blending ratio of such a film forming component is preferably 0.1 to 10% by weight. This is because if the blending amount is less than the predetermined weight percent, the oily active ingredient becomes oil droplets after the film is formed, or white turbidity is likely to occur due to the precipitation of the crystalline active ingredient. In this case, the drying time is longer than 10 minutes and the amount of dust attached is increased, which is not preferable.
[0022]
The organic solvent used in the present invention is an organic solvent having a saturated vapor pressure at 20 ° C. of 1200 to 1500 Pa. In the case of a fast-drying organic solvent exceeding the drying rate (with a saturated vapor pressure at 20 ° C. exceeding 1500 Pa), the liquid transparent pest control agent having a specific viscosity is applied during the coating operation before the film thickness becomes constant after coating. Since the film starts to dry, the coating thickness is not uniformly formed, and unevenness that can be discerned with the naked eye occurs. In addition, when an organic solvent having a drying speed less than a predetermined drying speed (saturated vapor pressure at 20 ° C. is less than 1200 Pa) is used, it is easy to attach dust by the completion of drying when the coating is dried outdoors, and the treated surface is transparent ( (Clear) is not finished.
[0023]
Specific examples of such a predetermined drying organic solvent are paraffinic hydrocarbons (= aliphatic saturated hydrocarbons) of the general formula C n H 2n + 2 such as isoparaffin and n-paraffin, and have a carbon number of n. = 8-16, preferably 9-10.
[0024]
The transparent pest control agent of the present invention that can be manufactured by batch mixing the above-mentioned raw materials is used by being applied to the outdoor side such as a glass surface on which the target pests fly, but as a pretreatment, the dirt on the coated surface is sufficiently removed. It is preferable to keep it. This is because such dirt causes unevenness and fogging after application.
[0025]
As a coating method, brush coating or roller coating is likely to cause unevenness. Therefore, in order to reliably form a transparent film, spray coating is preferable. The sprayer to be used is preferably a spray gun with a trigger (trigger), and sprayed evenly from the position 20 to 30 cm away from the glass surface or the like so that the entire surface of the coating surface is wet. In this way, there is no dripping at a coating amount of about 20 ml / m 2 , and a uniform film thickness can be applied.
[0026]
If such a film is dried for about 2 to 3 minutes without being wiped off after application, a uniform film is formed.
[0027]
In addition, the above-mentioned transparent pest control agent can be applied to the use of a transparent pest control agent for coating a glass surface, particularly a transparent pest control agent for coating a transparent glass surface. Known additives such as an absorbent, an antioxidant, and a fragrance may be blended, and a pigment or the like may be added when a translucent film is formed.
[0028]
【Example】
[Examples 1-31, Comparative Examples 1-9]
With the formulation shown in Tables 1 to 4, the raw materials were mixed together to produce a transparent pest control agent.
The following evaluation tests (a) to (c) are performed on the obtained transparent pest control agent, and (a) uniform coating property, (b) dust adhesion to the coating, and (c) transparency of the coating are examined. The results are shown by symbols in Tables 1 to 4. The results are shown in two stages: good (◯ mark) and bad (x mark).
[0029]
(A) Uniform coating property The transparent pest control agent of the example or comparative example is sprayed onto a transparent glass plate with a spray gun to apply 20 ml / m 2 and dried in a room at 20 ° C. Whether or not unevenness (unevenness) was formed on the coated film was determined with the naked eye.
[0030]
(B) Dust adhesion of the coating The transparent pest control agent of the example or comparative example was sprayed onto a transparent glass plate with a spray gun and applied at 20 ml / m 2 and dried outdoors at room temperature for 10 minutes. Then, it was determined with the naked eye whether or not dust was adhered to the formed film.
[0031]
(C) Transparency of coating The transparent pest control agent of Example or Comparative Example was sprayed onto a transparent glass plate with a spray gun, applied to 20 ml / m 2 , dried in a room at 20 ° C., and formed. It was determined with the naked eye whether the coated film had cloudiness such as cloudiness.

[Table 1]
[Table 2]
[Table 3]
[Table 4]
As is apparent from the results in Table 4, in Comparative Examples 1 to 4 in which the active ingredient exceeds a predetermined amount, cloudiness occurred in the dried film. Further, in Comparative Examples 5 to 8 in which the film forming component exceeded a predetermined amount, dust adhered to the dried film, or cloudiness occurred in the dried film. Moreover, in Comparative Example 9 in which the active ingredient and the film-forming component were blended in excess of a predetermined amount, dust adhered to the dried film and clouding occurred in the film.
[0037]
On the other hand, in Examples 1 to 31, which satisfy all the predetermined conditions, satisfactory results were obtained with respect to all of the uniform coating property, the dust adhesion of the coating, and the transparency of the coating.

【The invention's effect】
As described above, the present invention provides a transparent pest containing a pest control active ingredient, a film-forming component comprising a transparent organic compound capable of dissolving the pest control active ingredient, and a predetermined drying organic solvent. Since it is a control agent, a transparent pest control agent can be applied evenly to the treated surface, transparency can be maintained when dried, and it is difficult for dust to adhere to the coating, thus increasing the transparency of the pest control coating. There is an advantage that it can be maintained for a long period of time, and the pest control property is weather resistant.
