However, as described above, long-term performance cannot be obtained by applying a fungicide, and it is necessary to repeatedly use the fungicide. Moreover, the fungicide has a bad odor such as a solvent. At the same time, it reacts with other chemicals to generate toxic gas, which causes the user to be poisoned. In addition, there is a disadvantage in that when a mildew proofing agent is applied to the base, the color gradually differs from the surrounding color.

[0004]

In order to eliminate such drawbacks, the present invention provides a silver-based inorganic antibacterial agent at a humid place on its base or its surface, and further adds a fluorine coating to remove dust or the like. As a surface layer that does not easily adhere to the building, the structure has significantly improved mold resistance, stain resistance, cost, workability, and corrosion resistance,
It proposes a construction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a building and a structure according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing an example of a building and a building according to the present invention, where 1 is a building building, 2 is a roof, 3 is an outer wall, 4 is a window, 5 is an attic ventilation vent, 6 is an underfloor vent, and 7 Is the entrance door and 8 is the foundation.

Reference numeral 9 denotes an exhaust port of a ventilation fan, as shown in FIG. 2, in which a through hole 11 is bored between an inner wall 10 and an outer wall 3 of a kitchen or the like, and a pipe 12 with a heat insulating material is attached.

FIG. 3 is an explanatory view showing a part of the bathroom, which comprises a bathtub 13, an inner wall 10 such as tiles in the bathroom, a ceiling 14 and a heat insulating material 15.

FIG. 4 is an explanatory view showing an essential part of the present invention in an enlarged scale. The inner wall 10, the outer wall 3, for example, in the case of a mortar wall, an undercoating film 16, a fungicide, and a bactericidal layer 1 comprising an antibacterial agent layer.
7, and a fluorine coating film 18 is laminated and integrated thereon in this order.

To explain further, the inner wall 10 and the outer wall 3 are made of one or more kinds of mortar wall, dry siding material (ceramic-based, metal-based), tile-based, etc.
Material having adhesion to the coating film, film, etc. of 7, such as polyester resin, polyether resin, polyurethane resin, alkyd resin, phenol resin varnish, methacrylic resin, styrene resin, acrylic resin, urea resin, urethane rubber-based The primer is composed of one or more of

The bactericidal layer 17 contains at least one of barium metaborate, Paris green, red cuprous oxide, silver complex salt, silver vermillion, zeolite powder carrying an amine complex of an antibacterial metal, and zeolite containing an amine complex silver ion as it is. Alternatively, it is dispersed in a resin and applied evenly. The amount of addition is about 0.1 to 40 parts by weight, and the particle size is about 0.1 to 1000 μm, though it is added depending on the purpose.

The fluorine coating film 18 functions as an overcoat layer that covers the surface of the sterilization layer 17, and is provided to exhibit stain resistance and weather resistance. Of course,
The content of fluorine is 50 to 90% (weight ratio), and vinylidene resin, acrylic resin, thermosetting fluoroethylene vinyl ether resin (FEVE), etc. are used as vehicles.
It is used as a paint by adding a curing agent, a pigment, a solvent, etc. to this and has a film thickness of about 5 to 50 μ (dry). The type may be either a baking type or a room temperature curing type.

Next, a brief explanation of the construction example is given in FIG.
It is assumed that the germicidal layer 17 and the fluorine coating film 18 are formed on the entire area of the ceiling 14 of the bathroom. That is, this portion is likely to be moldy and dirty. So the ceiling 1
Reference numeral 4 is a mortar wall as shown in FIG. 3. After the surface treatment such as a sealer is applied to the surface of the mortar wall, an undercoat coating film 16 containing a polyether resin as a main component is applied and dried and cured. Zeolite powder in which 100 parts by weight of polyether resin carries silver amine complex (particle size: 0.1 to 100 μm)
20 parts by weight of a coating material is evenly applied at about 100 microns (wet) to form a sterilizing layer 17 which is dried and cured, and further contains FEVE (55% fluorine content) as a main component. It is sufficient to apply the fluorine-containing coating at about 20 microns (wet), dry and cure.

An accelerated test was conducted on a sample manufactured in the same manner as the inner wall 10 thus coated. That is, Staphylococcus and Escherichia coli broth 2 cultivated in meat extract with meat extract
ml was dropped on the sample, a membrane filter having a diameter of 25 mm was placed on the sample, and the mixture was cultured at 37 ° C. for 24 hours. Then, add phosphate buffer and vibrate for 1m
The number of surviving bacteria was measured by the take-out pour plate culture method.

The test results are shown in Table 1.

[Table 1]

Thus, the antibacterial property was sufficient. This is probably because dust and dirt could not be attached due to the fluorine coating film 18.

As a test method for mold antibacterial, a part of the above sample is cut out, and a spore suspension (second group: penicillium, mitrinum, fourth group: grandsporium) is cut on the surface according to JIS-Z-2711. , And ground sporeoides), and the test results of mold resistance when cultured at 27 ° C. for 4 weeks are shown in Table 2.

[Table 2]

What has been described above is one embodiment of the building and the structure according to the present invention. By further applying enamel or silicone paint on the fluorine coating film 18, it is possible to greatly reduce the adhesion of dust. . Of course, it is necessary to modify or interpose a coupling agent between the fluorine coating 18 and the silicone coating. Further, the material of the inner wall 10, the outer wall 3, the ceiling 14 and the like can be formed of resin, mortar and metal in the same manner, and a dry type outer wall material such as a ceramic siding material or a coating film of a metal siding material. The sterilization layer 17 and the fluorine coating film 18 are formed on itself, and the building structure 1 using the same also has the same effect.

[0018]

As described above, in the building and the structure according to the present invention, it is not always necessary to apply them to the entire surface such as the inner and outer walls, the bathroom, etc., and at a low cost by applying only to the places where mold and stains are likely to occur, Moreover, it is possible to form an antifungal, anti-staining, and antibacterial surface regardless of the shape. Fluorine coatings have very little dirt and dust due to adhesion of dust, and have few nutrients such as mold. It has the advantages of weather resistance, durability, and synergistic effect with the sterilization layer for a long period of time, with the performance of being almost free from mold and stains. Features such as
effective.
