DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-layered insect repellent for controlling and controlling pests such as termites and house mites.

[0002]

2. Description of the Related Art Conventionally, as a method of controlling termites, a method of spraying various chemicals such as powder on the foundation of a house has been known. On the other hand, as a method of exterminating house mites, a method of spraying a liquid or a powder or the like on a tatami mat or a method of laying in a sheet is adopted.

[0003]

However, the above-mentioned chemicals have a problem that they are difficult to handle in order to ensure safety, have a function of controlling termites and house mites, and have a constant effect of controlling such pests. There is no known device which can be maintained easily and has a humidity adjusting effect and is easy to handle.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to disclose an insect-controlling multilayer body having both a pest control function and a humidity control function, and which is easy to construct and lay.

[0005]

In order to solve the above-mentioned problems, the insect-controlling multi-layer body according to the present invention has a gap through which at least one of a pair of sheet-like base materials overlapping each other can pass through a powder particle. It is formed by a permeable member, and is formed of one or two or more hygroscopic substances in a group of solid materials such as natural zeolite, artificial zeolite, sepiolite, silica gel, silicic anhydride, diatomaceous earth, between the pair of sheet-like substrates. The pair of sheet-like substrates are bonded to each other with a powder interposed therebetween.

[0006]

According to the insect-controlling multi-layer body of the present invention, since the moisture-absorbing substance powder is present inside the permeable member, the moisture in the atmosphere is absorbed through the gaps, so that the humidity is controlled. As a result, the environment becomes difficult for house mites to live in due to a decrease in humidity. Since it is a sheet, when it is laid on the floor of a house, etc., particles of the hygroscopic substance are scattered to the outside of the base material through the gap of the permeable member, so that pests such as house mites and termites When walking or flying, particles of the hygroscopic substance adhere to the surface of the skin. These pests have the property of contraindicating the attachment of such granules to their own body, so when the granules adhere to the body, they damage their skin with their own limbs in an attempt to wipe away the granules . Therefore, the body fluid leaking from the wound is further absorbed, and the pest is killed. Furthermore, since it is a sheet body and the content is a hygroscopic substance, the built-in amount can be larger than that of a medicine or the like. Therefore, the insecticidal effect of the pest is constantly maintained. In addition, it is easy to handle because it does not involve the danger of drugs.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a multilayer structure for insect control according to an embodiment of the present invention.

FIG. 1 shows a partial cross-sectional structure of an insect-controlling multi-layer body according to a first embodiment of the present invention.

In FIG. 1, reference numeral 10 denotes a sheet as a multi-layered body for insect repelling.
A pair of substrates 11 and 12 are fixed to each other by a binder 14 with a hygroscopic substance 13 interposed therebetween.

The base material 11 serves as a base laid on a wall surface or a floor surface, and may have no fiber gap. The base material 11 is made of a material such as paper, cloth, board, and resin sheet. Plain paper, resin processed paper,
Paper using synthetic fibers, kraft paper, Japanese paper, and the like are included. Examples of the cloth include felt, nonwoven cloth, cloth using fibers, and the like. Examples of the board include thin plywood and laminated wood. Examples of the resin sheet include PP, PE, PET, ABS resin, acrylic, polyvinyl chloride, and other plastic materials.

The base material 12 has a gap for spraying particles of the hygroscopic substance 13 from the surface. Paper, cloth, resin sheet, or the like is used as the base material 12 having the gap.
The material of the paper, felt, and resin sheet may be the same as that of the substrate 11. In the case where a resin sheet is used, it is necessary that a large number of holes, such as a mesh sheet and a perforated sheet, through which the particles of the hygroscopic substance 13 pass are opened.

Examples of the hygroscopic substance 13 include natural zeolites, artificial zeolites, sepiolite, silica gel, talc, silicic acid, diatomaceous earth, etc.
Use a material pulverized to a size of 0 micron or less. The particle diameter of 30 μm or less and the particle diameter of 60 μm or less are set so as to correspond to the distance between the hairs on the skin surface of house mites and termites. Each of these hygroscopic substances may be composed of a single material or may be a composite.

FIG. 15 shows the particle size distribution of an artificial zeolite powder as an example of a hygroscopic substance. The horizontal axis represents the particle size (μm), and the vertical axis represents the passing mass percentage (%). I have. As this powder, an artificial zeolite powder having a particle size interval starting from approximately 2 to 3 μm and having a particle size of 100 μm and passing through completely is used. As an example, this artificial zeolite is obtained by mixing caustic soda with fly ash and performing hydrothermal synthesis at 90 ° C. to 210 ° C.

As the binder 14, an acrylic adhesive, glue or the like is used.

In order to manufacture the sheet 10 according to the present embodiment, a powder of the material 13 made of a moisture-absorbing material is formed into a paint and applied to the substrate 11. In this application step, a portion on which the binder 14 is placed is provided. After applying the hygroscopic substance 13, the binder 1
The sheet 10 is manufactured by adhering and bonding the substrate 12 on which the substrate 4 is placed to the substrate 11.

In FIG. 4, the permeable substrates 12, 12 are bonded together and contain a powder 13 of a hygroscopic substance. In this way, pests such as termites and house mites are controlled.

That is, when the sheet 10 is laid under the mat 15, the humidity of the mat 15 is reduced, and it becomes difficult for house mites to live. In addition, the house mites that previously inhabited the mat 15 contraindicate the granules of the hygroscopic substance 13 coming out of the gaps between the base material 12 of the sheet 10, but these granules adhere to the body of the house mites. The house mite then tries to shake it off, damaging the surface of its skin and causing its body fluid to leak. Since the body fluid is absorbed by the hygroscopic substance 13, the house mites die.
Since the same occurs with termites and the like, if the sheet 10 is fixed around the base pillars of a house or the like, the termites are exterminated and insect repellent effects are exhibited.
