実用化には至っていなかった。(Prior Art) Gypsum materials have been widely used as building materials such as wall materials, ceiling materials, and interior decoration materials. However, gypsum (CaSo
4.2ttio) has high water absorbency, so bacteria and mold may develop during long-term use, and the areas where bacteria and mold occur will discolor, causing problems in appearance.
The occurrence of bacteria, mold, etc. itself was unfavorable from a sanitary standpoint. Therefore, attempts have been made to mix organic fungicides such as diphenyl ether-based fungicides and chlorhexidine-based fungicides into plaster materials in order to impart antibacterial and anti-fungal properties, but it has been found that the bactericidal action is not long-lasting. It had shortcomings and was not put into practical use.

This was completed in order to provide a gypsum material with anti-dental and anti-mildew properties that can solve dental and hygienic problems.

等がある。The gypsum material referred to in the present invention is particularly suitable as a building material, such as plaster for walls and ceilings that uses calcined gypsum as the main raw material, or gypsum that is made of calcined gypsum with fibers, or sawdust ( Gypsum board for ceilings, walls, and partitions, which is a board-shaped material made by adding clay, and has excellent waterproof, soundproofing, moisture-proofing, and heat insulation properties, or ceilings, partitions, and partitions made from calcined gypsum mixed with sawdust, etc. There are plaster blocks for partitions such as walls.

ととなる。In the present invention, soluble glass powder or the like that can elute silver or copper ions at a constant rate is dispersed in the above-mentioned various architectural plasters to exhibit antibacterial and antifungal effects. This meltable glass is a general term for glasses whose composition has been adjusted taking into account the physical and chemical properties of the glass so that it has a controlled dissolution rate.There are several meltable glasses containing silver or copper compounds. Silver or copper ions can be eluted at a defined constant rate over any period of time from hours to years. The eluted silver or copper ions inhibit the growth of bacteria and microorganisms and exhibit antibacterial and antifungal effects.

This is preferred because if it is less than 0.1% by weight, the antibacterial and antifungal effects will be insufficient, and if it exceeds 15% by weight, the original characteristics of gypsum material will be lost. In this way, in the present invention, sufficient antibacterial and
This allows silver or copper ions to be eluted in an amount sufficient to exert an antifungal effect.

As a result, the soluble glass gradually dissolves, and silver or copper ions, which exhibit antibacterial and antifungal effects, are eluted. The action of these silver or copper ions completely prevents the growth of bacteria and mold on the gypsum material, and also prevents discoloration due to mold and the like.
