2. Description of the Related Art In recent years, sick house syndrome has become a problem in the interior of houses immediately after new construction or renovation, and volatile chemical substances contained in plywood and wallpaper adhesives are diffused into the air in the interior of the interior. It is said to cause headache, nausea and chemical sensitivity (for example, allergy), and is thought to be caused by the use of an organic adhesive containing an organic compound such as formaldehyde, toluene, or xylene.

[0003] In addition, not only residents of the house, but also workers who directly handle organic adhesives, which are problematic in interior construction work and plywood manufacturing sites, have become a problem.
The Ministry of Labor and others are going to conduct a substantive investigation.

Conventionally, examples of organic adhesives include starch, polyvinyl alcohol (hereinafter abbreviated as PVA), synthetic rubber latex and vinyl acetate or acrylate emulsion, urea resin, melamine resin, phenol resin and the like. A single compound or a mixture of two or more compounds has been used. However, during the process using these adhesives, or during disposal of the product during or after use, there are some which have an adverse effect on the environment or human body.

[0005] Particularly, urea resins, melamine resins, phenol resins and the like, thermosetting resins containing formaldehyde as one component have been widely used in combination and used in large quantities because water resistance and heat resistance can be obtained. However, formaldehyde generated during the bonding process using the adhesive or during use of the product is currently regarded as a problem.

As an example of the inorganic adhesive composition, in a broad sense, a general inorganic adhesive material is sometimes referred to as cement, and usually refers to Portland cement.
The main component is lime, a silicon compound (for example, silicon dioxide) or a metal oxide (for example, iron oxide or alumina). As an example of the water glass adhesive, there is a concentrated aqueous solution of potassium silicate or sodium silicate.

[0007] Negative ions, which are to be used in the present invention, were discovered in Germany about 100 years ago, occur at the shores of waterfalls, in forests and on the shore, and when taken into the human body through the skin and breathing, make the blood slightly alkaline. It is said that it has antioxidant constitution and is effective for maintaining health, but other effects of negative ions are said to have antibacterial effect and deodorant effect, but application development to adhesives is delayed ing.

[0008] Conventionally, tourmaline ores are known to have electrodes at both ends of the crystal to have a property of permanently retaining potential, a property of generating a piezoelectric effect, a property of generating far infrared rays and negative ions, and the like. It is known that the antibacterial and deodorizing effects of the surroundings have a positive effect on human health by utilizing the antibacterial and deodorizing effects of these surroundings. At present, there are only a few development examples that can be applied to applications.

Among them, there are a few examples of the development relating to the negative ion and the adhesive, for example, adhesives such as far-infrared rays, negative ions, deodorant, antibacterial, antifungal, insect repellent, and chemical sensitivity. It is an object of the present invention to provide a composite material provided with characteristics such as countermeasures and freshness retention, and a tourmaline powder is added in a weight ratio of 0.1 to an adhesive layer in which a plurality of layers are stacked.

The development of resin is not progressing. In addition, use examples of inorganic adhesives are limited at present, and it is considered that the adhesive is still a future material. Further, the development of application to an adhesive having an antibacterial effect and a deodorant effect, which are the effects of negative ions, to be used in the present invention, has been delayed.

[0011] In the development of a composite material having a tourmaline fine powder-containing adhesive layer disclosed in Japanese Patent Application Laid-Open No. 11-333965, tourmaline powder is added in an amount of 0.1 to 70% by weight to an adhesive layer in which a plurality of layers are stacked. It is a composite material that is contained and adhered, floor material, ceiling material, wall material, tatami material, metal interior board,
This is a development project characterized by being used as a building material, a packing material, and a packaging material for residential heat insulating materials, but it is assumed that tourmaline powder is contained in a known or commercially available adhesive for adhesives. Although organic adhesives are also included in the application, it is known that a large amount of negative ions are generated from inorganic compositions, and the inclusion of tourmaline powder in an organic adhesive has a negative ion effect. There is a problem of halving.

The present invention has been made in order to solve the above-mentioned problems, and can use a commonly used or disclosed known inorganic adhesive composition or inorganic plasticizer. It does not generate harmful substances to the human body during the production of adhesives, bonding, or disposal, and has water resistance, heat resistance, flame retardancy, heat insulation, and low air friction or high air friction.
