抗菌防黴性を有した釉薬に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glaze applied to the surface of ceramics and enamel, and more specifically requires cleanliness such as enamel products such as bathtubs and containers, and ceramic products such as tiles and sanitary ware. The present invention relates to a glaze having antibacterial and antifungal properties, which is suitable for use in local products.

By the way, conventionally, no glaze having antibacterial and antifungal properties has been known as a glaze applied to the surface of ceramics or enamel. On the other hand, in recent years, various organic and inorganic antibacterial and antifungal agents have been developed, and antibacterial and antifungal properties have been imparted by coating or kneading these with ceramics or enamel.

してしまうからである。However, even if these antibacterial and antifungal agents are applied to the surface of the glaze by a coating method, the antibacterial and antifungal agent may be peeled off by washing, resulting in poor durability. On the other hand, in the kneading method, although there is no problem in durability, it is currently impossible to knead the antibacterial and antifungal agent into the glaze. Because the glaze is made of glass components, it is melted and processed at high temperature, so it is removed by the organic antibacterial and antifungal agent at the time of processing. This is because they are eroded in the molten glass and lose antibacterial and antifungal properties.

One or more of copper and zinc are used. Further, if one or both of aluminum ions and fluorine ions are contained in hydroxyapatite, the corrosion resistance of hydroxyapatite to molten glass is increased, and it is possible to impart antibacterial and antifungal properties to glazes treated at higher temperatures. become. That is, hydroxyapatite alone is stable up to about 900 ° C. in the glaze, but it becomes stable up to about 1300 ° C. when it contains aluminum ions or fluorine ions.

Add water-soluble salts of copper and zinc and mix well. The amount of these antibacterial metals added is 10% or less, preferably 0.001 to 5%, based on hydroxyapatite.
The reason is that if it is less than 0.001%, the antibacterial and antifungal power is not sufficiently exerted, and if it exceeds 5%, it is not possible to expect more metal loading. The pH value for producing hydroxyapatite is preferably 5 to 7 because there is a possibility that hydroxyapatite is not sufficiently produced at 4.

The amount of hydroxyapatite added is preferably 1 to 20% by weight with respect to the glaze raw material.
That is, if it is less than 1% by weight, the antibacterial and antifungal activity is weakened, and if it is more than 20% by weight, the properties of the glaze may be impaired. Regarding the baking of the glaze having such antibacterial and antifungal properties, the same method as the conventional method in which the hydroxyapatite is not mixed can be adopted.
