In FIG. 1, reference numeral 1 denotes a mat for controlling insects,
This insect-proof mat 1 has a packaging sheet 3 surrounding a urethane foam 2 as a foam. Urethane foam 2 is assumed to be continuously foamed. Wrapping sheet 3
Has a gap for dispersing the particles 4 of the hygroscopic substance from the surface, and is made of a material such as papers, cloth, and a resin sheet. Examples of papers include plain paper, resin-treated paper, paper using synthetic fibers, kraft paper, Japanese paper, and the like. Examples of the cloth include felt, nonwoven cloth, cloth using fibers, and the like. Examples of the resin sheet include PP, PE, PET, ABS resin, acrylic, polyvinyl chloride, and other plastic materials. 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 powder 4 of the hygroscopic substance passes are opened.

As the powder 4 of the hygroscopic substance, natural zeolite, artificial zeolite, sepiolite, silica gel, talc, silicic acid, diatomaceous earth, or the like, which is pulverized to a particle size of 30 μm or less or 60 μm or less, is used. The particle diameter of 30 microns is set in accordance with the vegetation interval of the hair on the skin surface of house mites, and the particle diameter of 60 microns is adjusted in accordance with the vegetation interval of the termite hair. Each of these hygroscopic substances may be composed of a single material or may be a composite.

FIG. 4 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. This powder uses an artificial zeolite having a particle size interval starting from approximately 2 to 3 μm and having a particle size of 100 μm and having a size such that it passes completely. 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.

In order to manufacture the insect-control mat 1 according to the present embodiment, the urethane foam 2 absorbs the powder 4 of a moisture-absorbing substance. The method of absorbing the powder 4 into the urethane foam 2 includes, for example, a method in which the powder 4 is sprayed on the urethane foam 2 and then rubbed with a brush or the like, or a method in which the powder 4 is sucked through the urethane foam 2 by air. When the urethane foam 2 is covered with the packaging sheet 3 after the absorption of the powder 4 of the hygroscopic substance, the insect-proof mat 1 is completed, but the packaging sheet 3 may be quilted.

The insect repellent mat 1 according to this embodiment can be used between a tatami mat and a tatami floor, between a tatami mat and a board, a base or a base material of mats and carpets, a lining of a sofa, a chair, a futon, and a mat or a mat. Tick insects can be controlled and killed by being sandwiched between urethane foam of a futon or cotton of a futon. Also, since it is made in a mat shape, it is easy to handle.

FIG. 2 shows an insect-control mat according to a second embodiment of the present invention.

The insect repellent mat 10 is obtained by covering a fiber bundle 11 as a filling with a kraft paper 12 as a wrapping sheet, and the fiber bundle 11 is made of inorganic fiber such as glass wool or rock wool, cellulose fiber, cotton or cotton fiber. Organic fibers such as feathers are possible. As a method of causing the fiber bundle 11 to absorb the powder 4 of the hygroscopic substance as in the first embodiment, a method of absorbing the powder 4 through the fiber bundle 11 or a method of wrapping the fiber bundle 11 with the kraft paper 12 before the wrapping is performed. , Powder 4
A method is considered in which the fiber bundle 11 is placed on the fiber bundle 11 to be stirred and absorbed. After the powder 4 is absorbed by the fiber bundle 11, the insect bundle mat 10 is formed by coating the fiber bundle 11 with the kraft paper 12.

The insect repellent mat 10 can be disposed under the floor, above the ceiling, in the gap between the walls, etc., to kill and prevent insects from mites, and to absorb and control moisture.

FIG. 3 shows a vinyl flooring material 20 as an insect repellent mat according to a third embodiment of the present invention. The vinyl flooring material 20 is composed of a glass backing layer 21 mounted on the floor and a surface. A foam layer 23 made of rigid urethane foam or the like is formed between the vinyl layer 22 and the vinyl layer 22. The powder 4 of the hygroscopic substance made of the material described in the first embodiment is mixed in the foam layer 23.

According to the vinyl flooring material 20 according to this embodiment, the powder 4 is sprayed from the glass backing layer 21 to the floor surface, and the mites that inhabit between the vinyl flooring material 20 and the floor surface are insecticidally controlled. .

In the above embodiment, the fiber bundle 11 and the foam layer 23 made of urethane foam are used as the filling material. However, zeolite having a large particle size, vegetable fiber, animal fiber, synthetic fiber, glass fiber, hairy plastic, Feathers, animal hair, sawdust, ash, rags, and cut pieces of paper, pulp, cork, and the like may be used.

[0020]

According to the insect repellent mat of the present invention, since the foam containing the powder of the hygroscopic substance is covered with the powder-permeable member, moisture in the atmosphere is absorbed through the gap. Therefore, humidity control is performed. Also, when the particles of the hygroscopic substance are sprayed to the outside of the member through the gap of the permeable member, pests such as house mites and termites are contraindicated in attaching such particles to their own bodies. If the particles adhere to the body, they will try to wipe the particles and damage the skin,
Body fluids are absorbed and die. Furthermore, since the powder of the hygroscopic substance is contained in the foam, the insecticidal effect of pests is constantly maintained, and handling is easy because there is no danger like a drug.
