Description

  The present invention relates to a tick guide wall system.

  In recent years, due to the high airtightness of houses, the widespread use of air conditioners and the laying of carpets, etc., an environment suitable for mite habitat has been prepared to promote tick breeding. Mites are particularly abundant in bedding, carpets, and sofas, and cause allergic diseases such as asthma and dermatitis. Materials (for example, refer to Patent Document 1) and building materials (for example, refer to Patent Document 2) in which an acaricidal substance is mixed in paints, pigments and adhesives have been proposed.

  However, although the interior decoration materials and building materials described above are effective in suppressing the occurrence of ticks in the interior decoration materials and the building materials themselves, they do not reduce or eliminate ticks generated in the living room, but are more effective. It is the actual situation that there is a demand for proper extermination.

Methods for reducing and eliminating ticks include spraying acaricides such as organophosphorus compounds, carbamate compounds, pyrethroid compounds, attracting ticks with attractants, and physically removing them. A method for physically removing the film is known. As a method of physically removing using an attractant, for example, Patent Document 3 uses a pheromone flavor made of a fruit extract as an attractant, but in addition to this, a fatty acid ester having 14 to 18 carbon atoms, a food flavor In addition, a method of attracting mite individuals with an attractant such as a linear fatty acid having 4 to 18 carbon atoms, pheromone, etc., and collecting it with an adhesive or the like has been proposed. As a method of physically removing using a vacuum cleaner, a method of previously spreading a powdery composition for indoor treatment and a dietary attractant has been proposed in order to increase the removal efficiency. Recently, vacuum cleaners that deactivate mite allergens have also been proposed.

This allows the cleaner to clean the mite carcasses and mite discharges that have been killed on the wall, thus reducing and removing mite allergens without placing a heavy burden on the cleaner. .

  In addition, the wall surface as used in the present invention includes not only wall materials such as wall cloths and waist walls, but also house materials such as baseboards and window frame materials arranged on the walls, such as houses and offices. It refers to the wall surface of the living room.

  Examples of methods for killing ticks on the wall surface include, for example, applying sunlight (including room light) to the wall surface, heat drying, etc., and providing a sticker or the like to trap ticks and starve to death. Various methods are considered without being particularly limited. Among them, it is more preferable to kill the mites using sunlight because no special device is used.

  FIG. 1 is a schematic view illustrating the outline of the tick guide wall system of the present invention. In this example, ticks are killed by sunlight. For example, on the right wall surface at the position facing the left window, a place where there is more sunlight and there is no furniture in the vicinity is set as a tick killing area, and the tick is effectively killed in this tick killing area.

  The mite inducer in the present invention is not particularly limited as long as it induces mites on the wall surface. For example, the mite inducer is induced on the wall surface by an acaricide or a tick repellent, or the mite attractant is applied on the wall surface. It is considered to provide a tick. Of course, the above acaricides, mite repellents, and mite attractants may be used alone or in combination.

  In the case of using an acaricide or a tick repellent, for example, the acaricide 11 or the mite repellent constituting the mite inducer 1 on the acaricide / mite repellent installation surface 5 on the floor surface 7 as shown in FIG. The agent 12 may be provided. As a result, the mite on the floor surface 7 avoids the acaricide 11 or the tick repellent 12, and as a result, the mite can be guided to the wall surface 4.

  Examples of the acaricide 11 or the tick repellent 12 include organic phosphorus compounds, carbamate compounds, and bilesroid compounds. Specifically, organophosphorus compounds such as fenitrothion, diazinon, marathon, pyridafenthione, prothiophos, phoxime, chlorpyrifos; carbamate compounds such as carbaryl, propoxur, mesomil; natural pyrethrin, pyrethrin, allethrin, resmethrin, framethrin, phthalthrin, permethrin Pyrethroid compounds such as phenothrin, cypermethrin, ciphenothrin, fenvalerate, praretrin, empentrin, imiprothrin, transfluthrin; oxadiazole compounds such as methoxadiazone; pyrazole compounds such as fipronil; boron such as boric acid and borax Thiocyano compounds such as IBTA and IBTE; phenyl salicylate; benzyl benzoate and the like. These can be used alone or in combination of two or more.

  When the mite attractant 13 is used for the wall surface 4, for example, as shown in FIG. 1, it is considered that the mite attractant installation surface 6 in which the mite attractant 13 is provided at a higher position in the mite killing area A is formed. Is done. By this, the mite induced from the floor surface 7 with the mite attractant 13 can be killed in the mite killing area A before reaching the mite attractant 13, so that the mite allergen can be reduced and removed more effectively. Can do it.

  The tick attractant 13 includes fatty acid esters having 14 to 18 carbon atoms such as myristic acid ester, palmitic acid ester, oleic acid ester and stearic acid ester, food flavors such as chocolate flavor, almond flavor, cheese flavor and butter flavor, and pheromone. It may be a tick attractant 13 which is made of a tick attracting substance such as And the mite attractant 13 which used these mite attracting substances individually or in combination of two or more is carried on the wall surface 4. When the mite attractant 13 is supported on the wall surface 4, the mite attractant 13 is held on various liquid carriers or solid carriers such as a solvent, an emulsifier, a dispersant, a propellant, and a sustained release agent. The aqueous solution, oil, emulsion, suspension, wettable powder, propellant, and sustained-release agent may be supported on the wall surface 4 by application or adsorption.

The above mite attractant 13 is preferably supported on the wall surface 4 in the range of 5 mg / m ^{2 to} 10 g / m ² . If it is less than 5 mg / m ² , a sufficient attracting effect may not be obtained, and if it exceeds 10 g / m ² , the odor of the mite attractant 13 may be uncomfortable or cause discoloration of the wall surface 4. It is not preferable. The tick attractant 13 is preferably carried with a concentration gradient on the wall surface 4. Specifically, it is supported so that the concentration increases as the distance from the floor 7 increases. Thereby, mites can be effectively attracted to the wall surface 4.

  In the present invention, the tick attractant 13 may be held inside the microcapsule in order to impart a long-term sustained release property to the tick attractant 13. Examples of such microcapsules include inorganic hollow porous microcapsules, hollow microcapsules made of thermoplastic resin such as polyacrylonitrile and polymethacrylic acid, and hollow microcapsules made of thermosetting resin such as unsaturated polyester and polyepoxide. A capsule etc. can be illustrated. Preferably, an inorganic microcapsule whose wall material is made of silica or alumina is used. By holding the mite attractant 13 in the microcapsule as described above, the sustained release of the mite attractant can be controlled to the minimum necessary, and the sustained release of the mite attractant 13 can be realized for a long period of time. It is. Furthermore, when a photocatalyst is used as will be described later, it is possible to prevent the mite attractant 13 from being decomposed by the action of the photocatalyst. Moreover, the effect of the tick attractant 13 can be maintained for a longer period by breaking the microcapsules for a while with the photocatalyst.

  Although it does not specifically limit as a particle size of a microcapsule, In order to hold | maintain the tick attractant 13 enough and implement | achieve long-term sustained release, it is desirable to set it as 3-30 micrometers.

  Even when the mite attractant 13 is held inside the microcapsule as described above, it is considered to set the type and size of the microcapsule so that the effect of the mite attractant 13 extends into the room.

  The mites killed by the wall surface 4 and their discharge can be forcibly removed with a vacuum cleaner, etc., but a photocatalyst is provided on the wall surface 4 to inactivate mite allergens caused by mite carcasses and discharge. May be. Although the installation location of the photocatalyst is not particularly limited as long as it is the wall surface 4, it is more preferable that the photocatalyst is disposed in the same location as the tick attracting agent 13 or the tick killing area A. Furthermore, an adsorbent may be provided in the vicinity of the photocatalyst. Since this adsorbent can capture mite carcasses and mite discharges, the effect of reducing and removing mite allergens can be further improved.

  FIG. 2 is a cross-sectional view schematically illustrating a state where the photocatalyst 2 and the adsorbent 3 are disposed on the wall surface 4. As shown in FIG. 2 (a), a deactivation layer composed of the photocatalyst 2 and the adsorbent 3 may be formed on the surface of the attracting layer composed of the mite attracting agent 13 on the tick attractant installation surface 6 of the wall surface 4. As shown in FIG. 2B, a mixed layer composed of the mite attractant 13, the photocatalyst 2, and the adsorbent 3 may be formed on the wall surface 4.

  The photocatalyst 2 and the adsorbent 3 may be alternately arranged in a plane. This is because the adsorbent 3 or the group thereof is disposed in the vicinity of the photocatalyst 2 or the group thereof, and the photocatalyst 2 or the group thereof is disposed in the vicinity of the adsorbent 3 or the group thereof. It is considered that the group consisting of the adsorbent 3 and the group consisting of the adsorbent 3 are formed in a stripe pattern on the attracting layer. As a result, mite carcasses and mite discharges are captured in the vicinity of the photocatalyst 2 and the mite allergen is efficiently inactivated, thereby improving the effect of reducing and removing the mite allergen. FIG. 2 (a) shows an example in which the group consisting of the photocatalyst 2 and the group consisting of the adsorbent 3 are formed in stripes on the attracting layer.

Examples of the photocatalyst 2 in the present invention include TiO ₂ , ZnO, WO ₃ , Fe ₂ O ₃ , ZnS, Pt / TiO ₂ , and more preferably a visible light type photocatalyst. For example, a part of the oxygen site of titanium oxide is replaced with nitrogen atoms, or it is composed of Ti, O, and N elements formed by arranging nitrogen atoms or NOx between lattices of titanium oxide crystals and crystal grain boundaries. Examples thereof include nitrogen-doped titanium oxide, platinum-supported metals such as platinum, palladium, rhodium, and ruthenium, and NiOx, RuOx, RhOx, and the like as promoters. The above photocatalyst 2 can inactivate the mite allergen safely semipermanently.

  The adsorbent 3 is preferably an inorganic one, and examples thereof include activated alumina, zeolite, silica, apatite, diatomaceous earth, porous calcium silicate, powdered activated carbon, bentonite and the like. Of these, silica is preferably used.

  The photocatalyst 2 and the adsorbent 3 are preferably fixed with a binder. As such a binder, various resin components such as acrylic, urethane, fluorine, silicon, and acrylic silicon are used, and together with these resin components, the photocatalyst 2 and the adsorbent 3 are mixed with an appropriate solvent such as alcohol. Are mixed and dispersed in, and applied and fixed to the wall surface 4 by a general method such as spray, roll coater, flow coater, dipping or the like. Of these, acrylic silicon-based and silicon-based binders are preferable because they provide a high-strength and uniform coating film. A dispersant, a surfactant, a leveling agent, a thickener, a pigment, a dye, or the like may be contained depending on purposes such as improvement of dispersibility and stability and coloring. In addition, it is preferable to make the inactivated layer or the mixed layer porous by performing a treatment such as mixing a foaming agent in the binder or providing a ventilation hole. The presence of such pores not only effectively attracts ticks by emanating the mite attractant of the mite attractant 13 into the room, but also increases the surface area of the inactivated layer or the mixed layer to increase the surface area of the photocatalyst 2. In addition, the effect of the adsorbent 3 can be improved, and the trapping efficiency of mite carcasses and discharges can be further improved.
