Conventional technology. In order to impart insect-repellent properties to a sheet material, a structure in which a top coat containing an insect repellent is applied to the upper layer of the colored steel sheet is provided (for example, see Patent Document 1), and the substrate is coated with In the aqueous resin emulsion, a coating material such as colloidal cerium oxide, a cerium-based hydrophobic agent, or an anti-terming agent is blended (for example, see Patent Document 2), and the silicone rubber particles are adsorbed to the liquid by the adhesive layer. The structure on the surface of the material (for example, refer to Patent Document 3). [Patent Document 1] Japanese Laid-Open Patent Publication No. JP-A No. 2003-127 No. PCT Publication No. JP-A No. JP-A No. JP-A No. 2001-158702. 200819512 (2) Problem to be Solved by the Invention In the above-described conventional technique, since an insect repellent is mixed on a coating material and applied to a substrate, there is a problem that the insect repellent is used as a coating material. When the main component resin is diluted, the concentration of the insect repellent existing on the surface of the coating film is small, and the insect repellent effect of the insect repellent cannot be sufficiently exhibited. Further, when the insect repellent is mixed in the coating material, after the coating material is applied onto the surface of the substrate, it is usually dried by heating at about 100 to 150 ° C. However, due to the heat drying, it is possible to prevent it. The degeneration of the insecticide is degraded. In the configuration in which the silicone rubber particles to which the liquid insect repellent is adsorbed are fixed to the surface of the substrate by the adhesive layer, the silicone rubber particles are easily peeled off from the adhesive layer, and it is difficult to impart a durable insect-repellent effect. Means for Solving the Problem As a means for solving the above problems, the present invention provides a method of applying an insect repellent to an aqueous dispersion of a colloidal cerium oxide on a surface of a coating film of a substrate to be coated. Insect-resistant sheet for insect control treatment liquid. Generally, the insect repellent treatment liquid is prepared by adding an insect repellent to a water-alcohol mixed solvent dispersion of colloidal cerium oxide, but in this case, the water-alcohol mixed solvent dispersion of the colloidal cerium oxide. Among them, a surfactant is preferably added as a dispersing agent. EFFECTS OF THE INVENTION The insect repellent treatment liquid of the present invention is a liquid in which an insect repellent is added to a colloidal cerium oxide aqueous dispersion-5-200819512 (3), and a coating containing a resin as a main component is not used. The insecticide is not fixed by the resin to the minute irregularities on the surface of the colloidal cerium oxide, and the colloidal cerium oxide is fixed to the coating film on the surface of the substrate by hydrogen bonding. Therefore, in the present invention, since the insect repellent is present on the surface of the coating film of the substrate at a high concentration by using colloidal cerium oxide as a medium, the pest control effect of the insect repellent is effectively exerted, and even a small amount of antifouling can be obtained. Insecticides can also have a large insect-repellent sheet. Further, since the insect repellent is firmly fixed to the brushing surface by using colloidal cerium oxide as a medium, an insecticidal effect with durability can be obtained. [Embodiment] BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below. The substrate referred to as the object of the present invention refers to a cement board (wood cement board) to which wood reinforcing materials such as wood chips, wood pulp, and wood fibers are added, a cement extruded sheet, a pulp cement board, a gypsum board, and a tannic acid. Calcium plate, magnesium carbonate board, plywood, hard board, medium density fiberboard, iron board, metal building board, etc. -6- 200819512 (4) Painting Apply the surface of the substrate. Generally, the brush is applied by primer coating, intermediate coating, upper coating, and clear coating. The primer coating, the intermediate coating, the upper coating, and the cleaning coating are preferably aqueous emulsion coatings such as acrylic resin aqueous emulsion coatings and enamel-acrylic aqueous emulsion coatings. However, for example, acrylic transparent solution type can be used. A solution type coating such as a coating, and an aqueous emulsion coating and a solution type coating may be used in combination. Insect-repellent treatment liquid The so-called colloidal cerium oxide used in the insect-repellent treatment liquid of the present invention is a material in which one or more primary particles having a particle diameter of 5 to 1 Onm are combined to form secondary particles, and minute irregularities are formed on the surface. In addition to cerium oxide, other components such as alumina may be contained. In the present invention, as the dispersion medium of the colloidal cerium oxide, it is preferred to add an alcohol to water. The alcohol used in the present invention is preferably a water-soluble alcohol such as methanol, ethanol or isopropyl alcohol. This alcohol lowers the surface tension of the insect repellent treatment liquid of the present invention, and improves the affinity between the insect repellent treatment liquid and the lower coating film to improve the wettability of the insect repellent treatment liquid. In the insect repellent treatment liquid of the present invention, a surfactant is preferably added as a dispersant. As the surfactant, any of ordinary anionic, nonionic, and cationic surfactants can be used, for example, as an anionic surfactant, and a higher alcohol sulfate (Na salt or aluminum-7-). 200819512 (5) Salt), alkyl allyl sulfonate (Na or aluminum salt), alkylnaphthalene sulfonate (Na or aluminum salt), alkylnaphthalene sulfonate condensate, alkyl phosphate , dialkyl sulfosuccinate, rosin soap, fatty acid salt (Na salt or aluminum salt), etc., as a nonionic surfactant, polyoxyethylene alkyl ether, polyoxyethylene alkyl Phenol ether, polyoxyethylene alkyl ester, polyoxyethylene alkylamine, polyoxyethylene alkoxyamine, polyoxyethylene alkylamide, sorbitan alkyl ester, polyoxygen Ethylene sorbitan alkyl ester, etc., as a cationic surfactant, octadecyl acetate, imidazoline derivative acetate, polyalkylene polyamine derivative or its salt, ten Octamethyltrimethylammonium chloride, trimethylaminoethylalkylamide halide, alkylpyridine sulfate, alkane Trimethylammonium halide. Further, the surfactant may be used in combination of two or more kinds. In addition, the illustration does not limit the invention. The surfactant together with the alcohol lowers the surface tension of the insect repellent treatment liquid of the present invention, and the colloidal cerium oxide is well dispersed in the insect repellent treatment liquid, and the affinity with the coating film of the underlayer is also improved. In the insect repellent treatment liquid of the present invention, the colloidal cerium oxide is usually blended with 〇·1 to 2·0% by mass, the alcohol is blended with 2 to 10% by mass, and the surfactant is blended with 0·0 1 to 0 · 2 5 % by mass, the remainder is water. When the alcohol is contained in an amount of less than 2% by mass, the wettability of the insect repellent treatment liquid is deteriorated, and in the case where the content exceeds 10% by mass, the volatility of the solvent becomes large, and the coating is applied. Brushing operations have an adverse effect. Further, in the case where the surfactant is added in an amount of less than 质量·〇 1% by mass, the surface tension reduction effect by the surfactant is used or the gel -8 - 200819512
體氧化砂的分散效果就不明顯，另外，在超過〇 · 2 5質量 %地添加的情況下，會對所形成的防蟲處理膜的強度、耐 水性、耐久性等造成不良影響。因此，該防蟲處理液的表 面張力優選在25°C下爲20dyne/cm以下。 作爲所述防蟲處理液中所添加的防蟲劑，從對人體的 安全性的方面考慮，最好選擇擬除蟲菊酯類化合物。作爲 所述擬除蟲菊酯類化合物，例如可以例示出节氯菊醋（ permethrin )、丙烯除蟲菊酯（a 11 e t h r i η )、四溴菊酯（ tralomethrin )、氟矽菊酯（s i 1 a f 1 u o f e η )、醚菊酯（ ethofenprox)、苯醚菊酯（phenothrin)等。 所述防蟲劑通常被以0·0 1〜5質量％左右添加到所述 防蟲處理液中。 防蟲處理液的塗佈 在所述基材表面實施了塗刷後，在最終乾燥工序中， 塗膜通常在100〜150°c的溫度下被加熱乾燥。在塗膜的加 熱乾燥後，在常溫下將基材放置並冷卻。防蟲處理液的塗 佈優選在該塗膜的溫度降低至8 (TC以下，更優選降低至 7 〇 t：以下的狀態下進行。在所述溫度以下，不會有防蟲劑 的熱變性的情況。通常來說，所述防蟲處理液的塗佈使用 噴霧塗佈，然而除此以外，也可以使用塗佈機塗佈、輥塗 等眾所週知的方法。 塗佈量雖然沒有特別限定，然而通常來說設爲如下的 塗佈量，即，該防蟲處理液塗佈乾燥後得到的防蟲層的厚 -9- 200819512 (7) 度達到30〜80nm左右。 在所述防蟲處理液中，如上所述，膠體氧化矽爲多個 一次微粒結合凝聚了的二次微粒，所以在粒子表面形成有 微小凹凸，因此該防蟲劑就被膠體氧化矽表面的微小凹凸 捕捉吸附。這樣，捕捉吸附了該防蟲劑的膠體氧化矽就被 利用氫鍵固定於基材的塗膜（透明塗膜）表面。 以下將舉出用於更爲具體地說明本發明的實施例。 調製了下述的防蟲處理液1、2。 防蟲處理液1 防蟲處理液2 膠體氧化矽 2質量％ 2質量％ (二次粒徑5 μ m ) 防蟲劑（苄氯菊酯） 0.2質量％ 0.02質量％ 乙醇 4質量％ 4質量％ 表面活性劑* 0.02質量％ 0.02質量％ 餘量 水 水 聚氧亞乙基烷基酚醚 在木質水泥板基材表面利用丙烯酸樹脂水性乳液塗料 實施底塗塗刷、中塗塗刷、上塗塗刷，以及利用丙烯酸樹 脂溶液型塗料實施清潔塗刷，在l〇(TC〜1 l〇°C的加熱爐中 加熱乾燥了 20分鐘。The effect of dispersing the body oxidized sand is not remarkable, and when it is added in an amount exceeding 5% by mass, the strength, water resistance, durability, and the like of the formed insect repellent film are adversely affected. Therefore, the surface tension of the insect repellent treatment liquid is preferably 20 dyne/cm or less at 25 °C. As the insect repellent added to the insect repellent treatment liquid, it is preferable to select a pyrethroid compound from the viewpoint of safety to the human body. As the pyrethroid compound, for example, permethrin, pyrethroid (a 11 ethri η ), tetramethrin (tralomethrin ), and flumethrin (si 1) can be exemplified. Af 1 uofe η ), ethofenprox, phenothrin, and the like. The insect repellent is usually added to the insect repellent treatment liquid at a level of about 0.1 to 5% by mass. Application of the insect repellent treatment liquid After the surface of the substrate is coated, the coating film is usually dried by heating at a temperature of 100 to 150 ° C in the final drying step. After the coating film is heated and dried, the substrate is placed and cooled at normal temperature. The application of the insect repellent treatment liquid is preferably carried out in a state where the temperature of the coating film is lowered to 8 (TC or less, more preferably to 7 〇t: or less). Below the temperature, there is no thermal denaturation of the insect repellent. In general, the application of the insect repellent treatment liquid is by spray coating, but a well-known method such as coater coating or roll coating may be used. The coating amount is not particularly limited. However, in general, the coating amount is set such that the thickness of the insect-repellent layer obtained by coating and drying the insect-repellent treatment liquid is about -9-200819512 (7) degrees of about 30 to 80 nm. In the liquid, as described above, the colloidal cerium oxide is a secondary particle in which a plurality of primary particles are combined and aggregated. Therefore, fine irregularities are formed on the surface of the particles, so that the insecticide is captured by the fine concavities and convexities on the surface of the colloidal cerium oxide. The colloidal cerium oxide which has adsorbed the insect repellent is fixed to the surface of the coating film (transparent coating film) of the substrate by hydrogen bonding.
