Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention constantly releases negative ions, which are beneficial to the human living environment, and
Negative ion generation finish that can be used as a surface finishing material for building materials such as tiles, boards, blocks, etc. because it has antifouling properties, chemical resistance, water resistance, durability, weather resistance, aesthetic properties, etc. Liquid composition and building material.

[0002]

2. Description of the Related Art Various finishing paints have been used for the purpose of imparting beauty and durability to the surface of articles and improving or imparting various surface characteristics. For example, as building materials used for interior and exterior materials for construction, various materials such as tiles made of ceramic materials, wooden boards and gypsum boards, metal boards, cement boards, boards such as resin foam moldings, concrete blocks, etc. are suitable places. In particular, a finish paint is used around the water such as in a toilet to prevent various kinds of water-based dirt from adhering and to easily wipe off the adhered dirt.

On the other hand, it is widely known that a refreshing feeling and a refreshing feeling can be obtained in the vicinity of a natural waterfall or fountain where negative ions are generated. As a method of introducing such negative ions into the human living environment, there is an air cleaner that uses corona discharge or an electron beam to generate negative ions. Further, a method is also known in which tourmaline fine powder is mixed in a resin fiber filter, air is passed through this filter, and negative ions are supplied indoors.

[0004]

However, the above-mentioned two techniques are completely unrelated, and each has the following problems. When the finish paint is used around a toilet or the like as described above,
For example, if dark stains are attached, they can be easily found and wiped off, but if colorless or light-colored stains are attached in the form of fine droplets, it is difficult to find them, and they are left without being wiped off and give off an offensive odor. There was something to release. On the other hand, when corona discharge is used to generate negative ions, there is a problem in that negative ions simultaneously generate nitrogen oxides, ozone, etc., which adversely affect the human body. In addition, if only fine powder such as tourmaline is mixed into the filter of resin fiber, the amount of negative ions generated is very small, so forcibly letting air pass through the filter, such as friction force and physical stress. It required equipment and structures to provide stimulation. Therefore, the present inventors aim to propose a composition capable of simultaneously solving the problems in the above two techniques.

[0005]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above results, and comprises a liquid composition having a finishing property in the state of a coating layer and a fine powder of a mineral that generates negative ions. The present invention relates to a liquid composition having an anion-generating finish.

Garnets 99 to 99 are used as minerals that generate negative ions in the liquid composition having the above finishing properties.
Exciting material 1 consisting of an oxide of 1% by weight and zirconium, yttrium, silicon, or a rare earth element, which is obtained by firing a mineral.
By mixing 99% by weight, it has a finishing property in the state of the coating layer and can release negative ions constantly, and is suitable as a surface finishing material for building materials such as toilet tiles, boards and blocks. Can be used.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. The liquid composition in the present invention may be in any form such as ink or paint as long as it can be coated to form a layer (film) and has a finish in that state. Further, in order to impart high chemical resistance, water resistance and durability, it is desirable to use a curing (three-dimensional cross-linking) type resin, for example, a mixture of two liquids which is cured at room temperature, or heat or ultraviolet rays, It is desirable to use a material that cures with moisture, or a one-pack type curable resin coating. For example, when toilet tiles are used as the base material, it is assumed that they will be splashed with water frequently and that they will be cleaned with detergent (chemicals). If they are not too hard, apply them with a writing implement (graffiti) or a cleaning implement. Since it is assumed that scratches will occur on the film surface, it is desirable to use a three-dimensional cross-linking type resin that satisfies these required characteristics. Particularly preferably, an aqueous three-dimensional cross-linking type resin, for example, an aqueous two-component mixed curable liquid composition comprising an aqueous acrylic amine and an aqueous epoxy resin can be preferably used as in Examples described later. Such a water-curable resin has water resistance after curing, does not dissolve or swell in water, is safe against fire and odor during work, and can be diluted with water. Tools and tools can be washed with water on containers and brushes, and it can be applied even when water remains around the water, etc. It is considered that it contributes to the introduction and derivation of water in the inside.

Further, examples of minerals that generate negative ions include garnet, tourmaline, and the like. In addition, minerals composed of oxides of zirconium, yttrium, silicon, and rare earth elements by firing. Etc. can be used, and you may use these 1 type or in combination of 2 or more types. In particular, when 99 to 1% by weight of garnet is used in combination with 1 to 99% by weight of a mineral composed of an oxide obtained by firing a mineral containing all of zirconium, yttrium, silicon and rare earth elements, a remarkable negative ion releasing effect is obtained. It is considered that the latter mineral acts as an exciter that excites the negative ion generation action of the former garnet.

The addition amount of the above-mentioned anion-producing mineral is a liquid composition having a finishing property (solid content: 25%).
It is optimal to add 1 to 40 parts by weight of mineral to 100 parts by weight. The average particle size of the fine particles of the mineral is preferably 5.0 μm or less.

Further, for example, 99 to 1% by weight of the garnet and 1 to 99% by weight of a mineral composed of an oxide obtained by firing a mineral such as zirconium, yttrium, silicon or a rare earth element.
The principle of generation of negative ions in the air when used in combination with is that the water content in the air is a negative ion generation in which mineral fine powder that excites the electrical characteristics of garnet fine powder is kneaded, and a coating layer with a liquid composition that is finished is contacted. by immediately becomes a water molecule air containing small clusters, eventually electrically charged hydroxyl negative ions to the negative (H ₃ O ₂ ^-), and the large amount of negative ions in the air than garnet powder alone We obtained the knowledge that it occurs.

Based on the above findings, the present inventor uses the negative ion generating finishing liquid composition having the above-mentioned constitution as a board made of a ceramic material such as a tile, a wood board, a gypsum board, a metal board, a cement board, and a resin foam molded body. It is possible to exert the action of continuously generating negative ions in the indoor space and the action of imparting finishing properties including durability and anti-staining properties, etc. For example, when applied to toilet tiles, stains and odors are hard to attach, and the attached stains can be easily wiped off, and even if it is left without being wiped off, it can give off a bad odor with a deodorizing effect. Because there is no
It was confirmed that the air cleaning effect during use or cleaning was also achieved, and various other health improving effects were also achieved.
Similarly, when applied to interior boards and concrete blocks made of wood boards or gypsum boards, they prevent graffiti and stains, and are used for the purpose of forming a waterproof layer on the surface of resin foam moldings. May be.

With respect to the effect of generating negative ions, for example, the liquid composition for finishing negative ion generation having the above-mentioned structure is used to coat the tile surface with various tools and means such as spraying with a roll or spray, brushes and the like. In this case, if the surface area of 0.09 m ² is kept static, about 1000 (minus) negative ions will continue to be generated per 1 cm ^{3 of} air, and it will have a deodorizing effect, and will also have finishing properties, stain resistance, and easy wiping. It was confirmed that the product has sex.

The ammonia gas concentration decreased to 50 ppm in 4 hours and decreased to 10 ppm or less in 4 hours. In addition, nitrate nitrogen contained in the tiles used in the ammonia deodorizing experiment was analyzed.
The tile was immersed in purified water and analyzed for nitrate nitrogen and ammonia nitrogen in the immersion treatment water, and as a result, it was confirmed that nitrate nitrogen (NO, NO ₂ , NO ₃ ) was contained. As a result, it was actually measured that nitrate nitrogen (NO, NO ₂ , NO ₃ ) was contained in the tile after ammonia deodorization decomposition as nitrogen oxide produced by oxidation of ammonia. Furthermore, it was confirmed that the amount of negative ions generated in the tile after the deodorization experiment did not change from the amount before the experiment, and the negative ions were constantly generated.

Far-infrared radiation experiment: Measurement of far-infrared radiation characteristics from the tile confirmed that far-infrared radiation was emitted from the tile.

-Finishing (fouling resistance) experiment The tile was attached to the floor and wall of a toilet and used for one month. Dirt was easily wiped off, and the odor felt extremely weak compared to other toilets. Also, paint on the wall surface with magic or lacquer spray and use solvent (thinner).
However, the coating film (finished surface) was not scratched.

[0020]

As described above, the surface-treated substrate on which the coating layer is formed by using the liquid composition for finishing generation of negative ions of the present invention is hard to get stains, and can be removed from stains and graffiti. Since it has an easy effect and, at the same time, a large amount of negative ions are constantly maintained in a stationary state, it is possible to easily exert the deodorizing effect of ammonia odor and formaldehyde.
