ことが必要であった。In addition, there are places where microbial reactions are active. For example, green algae are likely to grow on the side walls of pools, the inner walls of fire prevention water, and the inner surfaces of aquariums. Especially in aquariums, the green algae that has grown can cause damage from the outside. This made viewing difficult and required periodic cleaning.
しかし、上記のような硝酸銀などを、プール内の側壁、
防火用水の内壁、水槽の内面に塗布しても、容易に液体

かなりの高濃度で硝酸銀などを含有させることが必要と
なり、大量の硝酸銀が必要となるとともに、流出したと
きの二次公害の恐れもあり、さらに、水槽内に入れられ
る魚貝類などにも悪影響を与えるおそれか高い。However, when silver nitrate as mentioned above is applied to the side walls of the pool,
Even when applied to the inner walls of fire prevention water or the inner surface of a water tank, it easily flows into the liquid and exhibits antibacterial activity only for a very short period of time. In addition, in order to maintain antibacterial properties over the long term, it is necessary to contain silver nitrate at a fairly high concentration in the liquid, which requires a large amount of silver nitrate, and there is a risk of secondary pollution if it spills. Furthermore, there is a high possibility that it will have a negative effect on the fish and shellfish that are kept in the aquarium.

とが好ましい。And, adhesion indicates that the silver compound is in contact with the surface of aluminum oxide and is located at a very close distance. Although it is preferable that all of the silver compound contained in the antibacterial agent adheres to the aluminum oxide, it is not necessary that some of the silver compound adhere to the aluminum oxide. Preferably, the silver compound is in contact with the aluminum oxide, and also preferably enters between the aluminum oxides in the aggregate of aluminum oxide, which is the feather-like particle as described above.

The surface always maintains high antibacterial properties due to the silver compound exposed on the surface of the formed coated and solidified product. The above drying method may be by leaving at room temperature, but preferably 110%
It is carried out at a high temperature of 120 to 400°C, more preferably 120 to 400°C. Such drying at high temperatures can be carried out, for example, by using a dryer or by blowing hot air onto the coated surface using an industrial dryer.

In order to improve film-forming properties, it is preferable to include an alumina sol to which no silver compound is attached, in addition to the alumina sol having antibacterial properties to which a silver compound is attached, to the surface of aluminum oxide in the alumina sol. Alumina sol with a silver compound attached alone has sufficient adhesiveness and film-forming properties, but its functionality is slightly lower than that of an alumina sol without a silver compound attached. Therefore,
By containing an alumina sol to which no silver compound is attached, the above functions can be improved.

菌性塗布面の被膜がより強固となる。Furthermore, the antibacterial agent of the present invention may strongly suppress the detachment of silver compounds adhering to the surface of aluminum oxide, so that the detachment of the silver compounds hardly occurs. For this purpose, it is conceivable that the antibacterial agent of the present invention be made into a two-component type, for example. Specifically, the first liquid is an antibacterial coating liquid containing an antibacterial alumina sol in which a metal having an antibacterial effect or a compound thereof is attached to the surface of aluminum oxide in the alumina sol, and the first liquid is The second solution to be applied to the coated and solidified surface is a surface coating solution containing alumina sol. The content of aluminum oxide in the second liquid is o, oi
~1G%, preferably 0.01-1%. By doing this, the drying of the surface coating liquid, which is the second liquid, suppresses the outflow of the silver compound in the antibacterial surface, and the silver compound partially exposed from the surface of the antibacterial coating provides antibacterial properties for a long time. In addition to maintaining its properties, the film formed on the antibacterial coating surface becomes stronger.

This can be done by forcibly pressing the silver compound.
