Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to furniture and household goods,
The present invention relates to a synthetic resin paint that is applied to floors, walls, ceilings, outer wall surfaces, and the like of various buildings to impart deodorant, antibacterial, and antifungal effects to an object to be coated.

[0002]

2. Description of the Related Art Conventionally, furniture and household goods, floors of various buildings,
It has been proposed to incorporate various deodorants, antibacterial agents, antifungal agents and the like into paints applied to walls, ceilings, outer walls and the like. It has also been proposed to combine these deodorants, antibacterial agents, antifungal agents and the like in the paints.
None of the paints has all the deodorant, antibacterial and antifungal effects. In addition, when a deodorant, an antibacterial agent, a fungicide, and the like are blended in a conventional paint, it is difficult to uniformly mix these blending agents in the paint, and these blends are stored during the storage of the paint. The compounding agent was separated, and a paint having stable properties could not be obtained. Further, there are drawbacks such as poor workability when applying these paints and the inability to obtain a uniform coating film. And there is no conventional deodorant paint which has an effective deodorant effect on all of ammonia, hydrogen sulfide, trimethylamine, methyl mercaptan and formaldehyde, which are main causes of malodor. Furthermore, conventional antibacterial paints have little effect on mold, and some of the proposed antifungal paints do not exhibit a sufficient antifungal effect.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The synthetic resin paint having deodorant, antibacterial, and antifungal functions of the present invention has a fine glass powder containing (A) a ceramic fine powder having an ion generating ability and (B) a heavy metal ion as active ingredients. Contains powder. (A) As the ceramic fine powder having an ion generating ability, a ceramic fine powder containing a radioactive mineral is used. For example, a radioactive rare earth ore containing thorium, uranium, or the like, zircon, zirconia,

Fine powder is mentioned, and a specific example is "N, N-powder" sold by Nishizaki Corporation. When the particle size of the ceramic fine powder is larger than the above range, it becomes difficult to uniformly mix the ceramic fine powder into the coating, and it is difficult to obtain a coating having stable properties and good applicability. In addition, it is difficult to economically produce a ceramic powder having a particle size smaller than 0.1 μm, and if such a ceramic powder is used, the cost is increased.

As the glass fine powder (B), it is preferable to use a glass fine powder having the same particle diameter as the above-mentioned ceramic fine powder (A) having an ion generating ability. When the particle size of the glass fine powder is larger than the above range, it becomes difficult to uniformly mix the glass fine powder into the coating, and it is difficult to obtain a coating having stable properties and good applicability. Further, it is difficult to economically produce glass powder having a particle size smaller than 0.1 μm, and if such a glass powder is used, the cost is increased.

The deodorant, antibacterial and antifungal synthetic resin coatings of the present invention can further improve the deodorant effect and the like by blending (C) a plant extract as an active ingredient. (C) As a plant extract, an extract having deodorant properties which is collected from the bark, pericarp, seeds, flowers, leaves, stems, roots and the like of various plants by distillation, extraction, or the like is used.

The content of (C) the plant extract (including the solvent and the like) is 0.01 to 15% by weight, preferably about 0.1 to 5% by weight, based on the whole synthetic resin paint. Further, the content of the binder resin is set to 1 to 50% by weight, preferably about 5 to 30% by weight, based on the entire synthetic resin coating other than the powder coating.

The synthetic resin paint having the deodorant, antibacterial and antifungal functions of the present invention includes components usually added to these synthetic resin paints according to the form of the synthetic resin paint, such as pigments.
A pigment dispersant, a leveling agent, a rheology modifier, an emulsifier, an emulsion stabilizer and the like can be added. The synthetic resin paint of the present invention uses a spray gun, a brush, a roller, a spatula, and the like, furniture and household goods, floors of various buildings,
It can be applied to surfaces such as walls, ceilings and outer walls. In the case of a powder coating, it can be applied to the surface of the object by electrostatic coating, fluidized immersion coating, or the like. A specific coating method may be appropriately selected according to the type of the object to be coated and the form of the synthetic resin paint. Further, if necessary, the synthetic resin paint of the present invention may be diluted and applied with a solvent or the like.

The synthetic resin paint of the present invention, by using the above components in combination, has all the deodorizing, antibacterial, and antifungal effects with one synthetic resin paint, and is a main cause of malodor. It has an effective deodorizing effect on all of ammonia, hydrogen sulfide, trimethylamine, methyl mercaptan and formaldehyde, and exhibits an excellent antifungal effect. Further, (A) radioactive substances such as thorium and uranium are contained in the ceramic fine powder having ion-generating ability to be contained in the synthetic resin paint of the present invention. Radiation is emitted to the extent that it does not adversely affect the environment, and acts on atmospheric components such as oxygen, nitrogen, moisture, and carbon dioxide to release electrons e ⁻ having a negative charge. This electronic e ^- is,
Reacts with water and carbon dioxide to produce negative ions.

The initial negative ions generated in this way and the positive ions generated at the same time recombine with ions of the opposite sign to lose charge or adhere to the aerosol (mainly water aggregate) existing around. And larger charged particles. Although the detailed mechanism is being elucidated, in the present invention, these charged particles act synergistically with (B) glass fine powder containing heavy metal ions and (C) plant extract to deodorize, antibacterial, and mold-proof. It is considered that the action and the like are remarkably improved. Furthermore, when the synthetic resin paint of the present invention is applied to the surface of furniture, household goods, floors, walls, ceilings, outer walls and the like of various buildings, negative ions absorbed by the human body after being released from the coating film are removed. By the action, the living tissue is activated, blood circulation and metabolism are improved, and a sedative effect such as relieving stress and a health promotion effect such as elimination of stiff shoulders and promotion of recovery from fatigue are exhibited.
