BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention including examples will be described with reference to the drawings. Components and the like having the same function, shape, and the like in each embodiment and the like are designated by the same reference numerals, and the description thereof will be omitted.

【0015】

(First Embodiment) FIG. 1 shows a titanium oxide panel as a first embodiment of the present invention. In FIG. 1, reference numeral 1 indicates a titanium oxide panel. This titanium oxide panel 1 has titanium oxide (titanium dioxide: TiO) having antibacterial, deodorant, antifouling functions, etc. by photocatalytic action (photocatalytic reaction).₂: Titanium oxide supporting layer 2 containing (also known as titania) is supported and formed on a base material 4 such as wood, resin material, metal material or concrete material or a composite material thereof via coating 3. Hereinafter, the titanium oxide supporting layer 2 is shown in a satin pattern in each figure. In the titanium oxide panel 1, the light receiving surface 2a containing ultraviolet rays is the front surface on the paper surface of FIG.

【0016】

Depending on the specific conditions in which the titanium oxide panel 1 is used, the base material 4 is, for example, an interior material used for a wall material such as a museum, a museum, a storage, a library, a clean room, a floor material, a ceiling material, and / or. The optimum material is appropriately selected depending on whether it is used as an outer wall material around a food factory or an exterior material such as a roof.

【0017】

As a coating technique for forming and fixing the titanium oxide supporting layer 2 as a titania film formation on the surface of the base material 4, all well-known methods such as a so-called sol-gel method and a binder method can be used. For example, when the base material 4 is made of a heat-resistant metal material, concrete material, brick, ceramic, or the like, a film forming / coating technique using the above sol-gel method is used. In this sol-gel method, in order to form the titanium oxide-supporting layer 2, a solution (sol) of organic titanium such as titanium alkoxide or titanium chelate, which is a precursor of titanium, is sprayed on the surface of the base material 4. After spraying or coating with a coating roller or the like, it dries to form a gel on the surface of the base material 4, and then it is subsequently fired at 500 ° C or higher to form a titanium oxide supporting layer 2. is there. According to the sol-gel method, the titanium oxide supporting layer 2 has a smooth film formation and a high hardness, so that it has an advantage of excellent durability.

【0018】

On the other hand, when the base material 4 is made of resin or other wood that is relatively sensitive to heat, a coating technique using the above binder method is used. In this binder method, the titanium oxide supporting layer 2 on which titania is generated is adhered and fixed to the surface of the base material 4 with an appropriate adhesive (binder), and the titanium oxide supporting layer 2 on which titania is generated from the beginning 2 is adhered and fixed. Therefore, high-temperature treatment for obtaining titanium is not required, and heat treatment, which is usually a binder curing temperature of, for example, 100 ° C. or less, is sufficient. Therefore, according to the above binder method, the hardness of the film is not so high as 2H to 3H in terms of pencil hardness because it is not heated, which has an advantage that the range of application to the target base material 4 is widened.

【0019】

FIG. 1 shows a partial cross section of the titanium oxide panel 1 finally obtained by using the above binder method, and the titanium oxide supporting layer 2 is coated on the base material 4 as an adhesive (binder). Adhesive and fixed to the surface. Further, when the above sol-gel method is used, the titanium oxide supporting layer 2 as a final film formed is substantially integral with the coating 2, but in FIG. 1, for the sake of clarity. It is shown briefly and schematically in.

【0020】

As the adhesive (binder), an inorganic system such as silica or water glass that is not affected by the decomposition function due to photocatalytic action, or an organic system such as silicone having a siloxane bond that can withstand the decomposition function is used. It is advisable to select the optimum binder in relation to the base material 4. The binder method is not limited to the above method, and for example, titanium peroxide is used as a binder, and when heated at 200 ° C. or higher, the property of changing the phase to titania, which exhibits anatase-type photocatalytic action, is applied. It may be one (see "Nikkei Mechanical, 1998.4, no.523, pp. 45-47").

【0021】

The density of titanium oxide-supported layer 2 per unit area of titanium oxide, the thickness of the titanium oxide-supported layer 2 including the coating 3, the thickness of the base material 4, or the outer peripheral shape thereof are determined by using the titanium oxide panel 1 as described above. Since it belongs to the design items designed according to the target conditions, the description thereof will be omitted.

【0022】

According to the titanium oxide panel 1 in the first embodiment, the decomposition action of titania decomposes microorganisms, organic substances, etc. adhering to the interior material and / or the exterior material, so that the interior material and / or the exterior material can be used. Contamination and deterioration of the surface of the interior and / or exterior materials due to adhesion, and the formation of coagulated substances such as dirt and dust on the surface of the interior and / or exterior materials brought about by organic substances including oil. Or, there is an advantage that odors and the like caused by them can be reliably prevented and removed at low cost. Further, when the titanium oxide panel 1 is used as the exterior material, the decomposition action of titania produces an antifouling effect on the surface of the exterior material, so that dust and dirt are treated by the influence of rain and wind, so that the so-called self-cleaning action is performed. And a durable antifouling effect can be obtained.

【0023】

FIG. 2 shows a modified example of the first embodiment. An example of this modification is a titanium oxide panel 10 in which the titanium oxide supporting layer 2 is supported on both sides of the base material 4 in a sandwich shape instead of the titanium oxide panel 1 in the first embodiment shown in FIG. Only that is different. In the titanium oxide panel 10, the light receiving surface 2a containing ultraviolet rays is the front surface and the back surface on the paper surface of FIG.

【0024】

Depending on the specific conditions under which the titanium oxide panel 1 is used, the base material 4 may be used for wall materials such as museums, storages, archives, clean rooms, flooring materials, ceiling materials, etc., and around food factories. The most suitable material is appropriately selected depending on whether it is used as an exterior material such as an outer wall material.

【0025】

According to the titanium oxide panel 10 in the above modification, by simultaneously using the titanium oxide panel 10 for the interior and exterior materials, the titanium oxide panel 1 of the first embodiment can be used for the interior material and the exterior material. Compared to the case where the titanium oxide panel 10 is used separately, there is an advantage that the base material 4 and the like, which are the constituent materials of the titanium oxide panel 10, can be saved, and the cost of the titanium oxide panel 10 itself can be reduced.

【0026】

(Second Embodiment) FIG. 3 shows an interior material as a second embodiment of the present invention. In FIG. 3, reference numeral 6 indicates an interior material panel used as an interior material. In the interior material panel 6, the titanium oxide panel 1 according to the first embodiment and the humidity control panel 5 provided with the humidity control material for adjusting the humidity are surfaced on the light receiving surface 2a side of the titanium oxide panel 1. It consists of those that are alternately pasted together. On the paper surface of FIG. 3, the front surface corresponds to the wall material, floor material, ceiling material, etc. on the interior side.

【0027】

The humidity control panel 5 of the interior material panel 6 has specific conditions for using it depending on the humidity control (humidity control range) of the humidity control material, that is, for example, a museum, a museum, a storage, a library, etc. The optimum humidity control material is selected depending on whether it is used as a wall material such as a clean room, a floor material, or a ceiling material.

【0028】

As a specific example of the humidity control panel 5, for example, "Art Wall" (trade name) manufactured by Fuji Seiko Co., Ltd. is preferably used. The main use of this art wall is as a secondary wall material for the interior of the storage of cultural properties, which blocks alkaline moisture from reinforced concrete and assists when the air conditioner in the storage breaks down. It has the ability to exert its humidity control effect and keep the change of indoor humidity moderate. When this art wall is used as a wall material, a natural wood plywood is used on the front side, a space is provided between the art wall and the humidity control material to enhance the humidity control effect, and an aluminum plywood is provided on the back side. Is used to block the alkaline moisture. In addition, the above art wall is a combination of a finishing humidity control material and a water resistant plywood when used as a ceiling material, and a combination of a natural wood flooring and a water resistant plywood when used as a floor material. It will be.

【0029】

As a specific example of the humidity control panel 5, not only the above-mentioned art wall but also all well-known humidity control panels provided with a humidity control material may be appropriately selected and used according to the purpose and use thereof. Needless to say, it's good.

【0030】

For the interior material panel 6, an appropriate adhesive or the like is used when the titanium oxide panel 1 and the humidity control panel 5 are alternately bonded to each other, but the present invention is not limited to this, and for example, a substrate (FIG. (Not shown) may be provided and attached on the substrate.

【0031】

FIG. 4 shows a modified example of the second embodiment. In this modification, instead of the interior material panel 6 in the second embodiment shown in FIG. 3, the titanium oxide panel 1 and the humidity control panel 5 are surfaced on the light receiving surface 2a side of the titanium oxide panel 1. The only difference is that the interior material panel 7 is formed by alternately pasting them in a checkered pattern.

【0032】

The arrangement pattern of the titanium oxide panel 1 and the humidity control panel 5 shown in FIGS. 3 and 4 is only an example thereof, and of course, an efficient arrangement pattern other than the above pattern may be used. Therefore, the titanium oxide panel 1 and the humidity control panel 5 may be alternately bonded so that the light receiving surface 2a side of the titanium oxide panel 1 is the surface (see claim 4).

【0033】

According to the interior material panels 6 and 7 in the second embodiment and its modified examples, the inhabitation and reproduction of microorganisms are carried out under a state where the humidity is maintained at a substantially constant humidity by the humidity control action of the humidity control panel 5. It is kept within the range corresponding to the humidity, and the decomposition action of titania of the titanium oxide panel 1 acts synergistically on this, so that microorganisms adhere to the titanium oxide panel 1 and the humidity control panel 5. Contamination and deterioration of the surface of the interior material, adhesion of dirt and dust on the interior material caused by organic substances including oil in the presence of microorganisms, formation of coagulated matter, and odor caused by them are more reliably and reliably performed. , Can be prevented or removed at low cost. As a result, there is an advantage that an optimum storage environment can be provided for the stored items in the museum, the museum, the storage, the library, the clean room, etc. by using the interior material panels 6 and 7.

【0034】

To explain the above action in more detail, for example, in a museum, a storage room, a library, a clean room, etc., an interior material panel using a humidity control panel 5 having a performance of keeping the humidity within a range of 50 ± 5% (relative humidity). If there are 6 or 7, microorganisms such as molds that can adapt and inhabit and reproduce under environmental conditions in the humidity control range of 50 to 60% relative humidity (assuming the temperature is about room temperature) It can be said that it is limited to those within a certain type range, and that its habitat / reproduction amount is generally reduced as compared with the case where its relative humidity is higher than the above-mentioned humidity control range. In such a humidity-controlled state, the habitat and reproduction of microorganisms are suppressed within the range adapted to the humidity as compared with the non-humidity-controlled state. Therefore, the decomposition of titania in the titanium oxide panel 1 The action works synergistically to prevent or remove contamination and deterioration of the surface of the interior material, adhesion of dust and coagulation, or odor caused by them more reliably and at low cost. You will be able to do it.

【0035】

This makes it possible to efficiently use the ratio of the titanium oxide panel to the interior material panel, for example, without using 100% of the titanium oxide panel for the interior material panel. For example, a museum, a museum, a storage, a library, a clean room. For example, it is possible to switch from the conventional dedicated air-conditioning equipment to a smaller and auxiliary one, or to abolish the air-conditioning equipment itself. The total cost can be reduced.

【0036】

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and can be modified in various ways.

【0037】
