Yes. However, these nets and sheets are apt to volatilize medicinal components under direct sunlight in summer, and are not provided with a heat-shielding means for suppressing the temperature rise of the net or sheet body as a volatilization prevention.

  Recently, with the main purpose or as a secondary purpose of reducing air conditioner power consumption in summer, mesh sheets have been installed on the balconies and verandas of houses and condominiums, and this has been extended to create a heat shield space, increasing the number of households used as daylight. ing. Although the use of such a mesh sheet at the window is expected to have an insect repellent effect, there is no mesh sheet having a heat-insulating property and having an insect-repellent effect. Also, in public facilities, large commercial facilities, offices, hotel accommodations, etc., a mesh sheet is used as a sunscreen for indoor windows. There has been no sunscreen that has a heat-shielding property and has an insect-proofing effect such as mosquitoes and moths. In addition, it is a curing mesh that is used around buildings and condominiums such as buildings and repair works. Especially, repair work for condominiums is coexisting with the daily lives of condominium residents. Instead, the mesh sheet itself is desired to have a heat shielding effect, and the use of a mesh sheet having an insecticidal effect such as mosquitoes and moths is also desired, but there are mesh sheets that have both a heat shielding effect and an insecticidal effect. There wasn't. In addition, these mesh sheets for sunshade, sunscreen, and construction work are not only heat- and insect-proof, but also unpleasant odors such as body odor, cooking odor, tobacco odor, toilet odor, pet odor, and chemical odor. There is also no thing that has a deodorizing effect for.

It is a combination of iron / silicon oxide, zinc oxide / silicon oxide, and the coverage of the multilayer thin film with respect to the entire interference mica particles is 30 to 70% by mass.
3) As the metal composite oxide pigment, 2 to 4 types selected from cobalt, chromium, manganese, bismuth, molybdenum, nickel, titanium, vanadium, antimony, barium, aluminum, magnesium, zinc, iron, copper, and tin Examples of the metal composite oxide composed of metal include iron-chromium composite oxide, iron-chromium-cobalt composite oxide, iron-chromium-cobalt-manganese composite oxide, and copper-chromium. Examples thereof include one or more black metal complex oxides selected from complex oxides, copper-magnesium complex oxides, copper-chromium-manganese complex oxides, copper-bismuth complex oxides, and manganese-bismuth complex oxides. .

  Further, in the mesh sheet of the present invention, the heat-shielding resin layer has a two-layer structure of inner layer / outer layer, and the inner layer is titanium oxide having a particle diameter of 0.6 to 1.5 μm coated with a thin film of silicon oxide or aluminum oxide. 1 to 10% by mass of particles, and 1 to 10% by mass of interference mica particles having a particle diameter of 5 to 50 μm formed by coating mica with a metal oxide multilayer thin film on the outer layer (uncolored heat In which the interference mica particles are dispersed in the plastic resin), or the heat-insulating resin layer has a two-layer structure of inner layer / outer layer, and the inner layer has cobalt, chromium, manganese, bismuth, molybdenum, nickel. A metal composite oxide pigment composed of 2 to 4 metals selected from titanium, vanadium, antimony, barium, aluminum, magnesium, zinc, iron, copper, tin, and more specifically, iron -Chromium composite oxide, iron-chromium-cobalt composite oxide, iron-chromium-cobalt-manganese composite oxide, copper-chromium composite oxide, copper-magnesium composite oxide, copper-chromium-manganese composite oxide, copper -1-10 mass% of 1 or more types of black type metal complex oxide chosen from bismuth complex oxide and manganese-bismuth complex oxide, and coat | cover mica with a metal oxide multilayer thin film in an outer layer. It may be one containing 1 to 10% by mass of interference mica particles having a particle diameter of 5 to 50 μm (a state in which interference mica particles are dispersed in an uncolored thermoplastic resin). By adopting such a two-layer structure, the heat rays are reflected first by the outer layer, and the heat rays are second reflected by the inner layer, which is preferable because the heat ray reflection characteristics can be further increased. In the case of a two-layer structure of the inner layer / outer layer, the inner layer and the outer layer include a pyrethroid compound inclusion body, and 0.1-10% by mass of the pyrethroid compound inclusion body with respect to the heat shielding resin layer (inner layer / outer layer).

  In the mesh sheet of the present invention, the heat-shielding resin layer may further contain odor adsorbing particles in an amount corresponding to 1 to 10% by mass of the heat-shielding resin layer for the purpose of imparting a deodorizing effect. Known activated carbon, zeolite, metal phthalocyanine complex (tetracarboxylic acid) or the like can be used as the odor adsorbing particles, but a mixture of white coal particles and electric ore particles in a mass ratio of 3: 1 to 1: 3 is particularly preferable. White charcoal particles are activated carbon that has a large number of fine pores and adsorbs odor molecules in the fine pores. Electric ore particles (tourmaline), on the other hand, generate a weak charge by receiving ultraviolet rays and heat rays from sunlight, or neutralize odor molecules with negative ions, and at the same time, this weak current is converted into white coal particles. The adsorption effect of is repeatedly regenerated. Therefore, as long as it has a combination of white coal particles / electric ore particles and continues to be exposed to sunlight, the deodorizing effect of the mesh sheet of the present invention is regenerated without falling into the adsorption saturation state. Stable and deodorizing effect is continued. If the content of the odor adsorbing particles with respect to the mass of the heat shielding resin layer is less than 3% by mass, a sufficient deodorizing effect may not be obtained. Further, if the balance of the white coal particles and the electric ore particles is out of the balance of 3: 1 to 1: 3, the regeneration susceptibility of the deodorizing effect when exposed to sunlight may not be expressed well.

The white coal particles were carbonized at 1000 to 1300 ° C using umegamegashi, blue oak, oak, etc. as raw materials, or carbonized at 800 to 1000 ° C with bamboo (Moso bamboo), and these red-hot states were subjected to rapid cooling with bare ash. It is activated carbon particles obtained by pulverizing glossy hard black coal to a particle size of 0.1 μm to 30 μm. Although the actual white coal particles are black, the appearance of the white ash is white, so it is called “white charcoal” to distinguish it from the charcoal without the ash. Examples of white charcoal include Bincho charcoal, oak white charcoal, oak white charcoal, and white bamboo charcoal. Electro ore particles are: iron tourmaline: NaFe ₃ Al ₆ (BO ₃ ) ₃ Si ₆ O ₁₈ (OH) ₄ , bitter earth tourmaline: NaMg ₃ Al ₆ (BO ₃ ) ₃ Si ₆ O ₁₈ (OH) ₄ Lithium tourmaline: Na (Li, Al) ₃ Al ₆ (BO ₃ ) ₃ Si ₆ O ₁₈ (OH) ₄ , Oren tourmaline: Na _1-x Al ₃ Al ₆ (BO ₃ ) ₃ Si ₆ O ₁₈ ( O, OH) ₄ , iron ash tourmaline: CaFe ₃ (Al ₅ Mg) (BO ₃ ) ₃ Si ₆ O ₁₈ (OH, F) ₄ , ash tourmaline: CaMg ₃ (Al ₅ Mg) (BO ₃ ) ₃ Si ₆ O ₁₈ (OH, F) ₄ , Voith tourmaline: Fe ₂ AlAl ₆ (BO ₃ ) ₃ Si ₆ O ₁₈ (OH, F) ₄ , Mafite voite tourmaline: Mg ₂ AlAl ₆ (BO ₃ ) ₃ Si ₆ O ₁₈ (OH, F) No. ₄ tourmaline ores, and the particle size thereof is 0.1 μm to 10 μm.

This effect is due to the “pyrethroid compound clathrate” used in the present invention, and pyrethroid compounds effective for the repelling effect of flying pests such as chironomid are cyclodextrin (Examples 1, 5 to 10), zeolite ( Example 2) When clathrate compounds such as montmorillonite (Example 3) and hydrotalcite (Example 4) are clathrated as a layered silicate, at least 3 months (7 to 7 months) from these clathrate compounds (September), an effect of stable and sustained release was observed. In addition, the mesh sheets obtained in Examples 1 to 10 are excellent in heat shielding effect, and by suppressing excessive temperature rise of the mesh sheet main body by the heat shielding effect, volatilization loss of medicinal components having repellent effect on flying pests is reduced. Suppression and thereby making the repellent effect of flying pests stable and sustainable for a long period of time have revealed the importance of the coexistence relationship between the heat shielding effect and the repellent effect of flying pests in the present invention. Further, the substance of the long-term stability effect of the flying insect pest repellent effect is that a large number of “pyrethroid compound inclusion bodies” are exposed on the surface of all the mesh sheets of Examples 1-10. It confirmed with the optical microscope of magnification. Moreover, it was recognized that all the mesh sheets obtained in Examples 1 to 10 have daylighting and air permeability, have a heat shielding effect, and further have a deodorizing effect.

  The mesh sheet of Comparative Example 1 lacks chironomid's repellent effect, and the mesh sheet of Comparative Example 2 has chironomid's repellent effect immediately after production and has an excellent KT50 value, but after 3 months of exposure indoors and outdoors in summer. Had lost its effect. The mesh sheet of Comparative Example 3 retains the chironomid's repellent effect immediately after production and after 3 months of exposure indoors and outdoors, but lacks daylighting and air permeability. It was also unsuitable for actual use, such as hot air in the summer season for applications such as sunscreens for indoor windows. The mesh sheet of Comparative Example 4 lacks the heat shielding effect because the area of the void is too large, and the substantial number of mesh sheet containing pyrethroid compound inclusions is substantially small, so that the chironomid repellent effect is sufficient. In addition, it was unsuitable for countermeasures against intrusion of chironomid, such as chironomid passing through the gap.

  The mesh sheet obtained by the present invention has a repellent effect on flying pests such as mosquitoes and moths in particular, is excellent in summer heat shielding effect, and suppresses excessive temperature rise of the mesh sheet body by the heat shielding effect. This prevents the loss of volatilization of medicinal ingredients that have repellent effect on flying pests, thereby making the repellent effect of flying pests stable and sustainable for a long period (at least for 3 months in summer), and the heat shielding effect reduces the room temperature. Lowering the rise by about 1 to 3 ° C contributes to the reduction of air-conditioner power, and is also effective in reducing unpleasant odors drifting in the usage environment. 1) Stretching at the construction and repair work sites in buildings and condominiums Curing mesh used in surroundings 2) Mesh sheet attached to balcony or veranda of houses and apartments and used as daylighting daylight 3) Public facilities, large commercial facilities, offices, hotels, etc. Accommodation, are suitable, such as a mesh sheet to be used as an indoor window for the date dividing the screen, such as. The mesh sheet of the present invention includes Culex mosquitoes such as Culex mosquitoes and Culex mosquitoes; Yabuca species such as Aedes albopictus and Aedes albopictus; It is effective for the prevention of flying pests such as butterflies, fleas, flies, flyfish, sand flies, and mosquitoes. The mesh sheet of the present invention retains the physical performance of a normal mesh sheet even if the repellent effect of flying pests is attenuated after long-term use (6 months or more). There is no problem in continuing to use it as it is for daily use screens.
