で保持されることとなる。EXAMPLE 1 First, a silver film is formed on the surface of silica stone by a wet coating method (for example, immersion in a silver-containing solution of an organic salt) or a dry coating method (for example, heating and depositing silver). Next, this silica stone is fritted (a material that has been melted and vitrified by dissolving raw materials such as feldspar and borax and then rapidly cooled by throwing it into water)
As a mill additive, it was added together with other additives, and this was pulverized by a mill to produce an enamel glaze as a suspension having an appropriate concentration and PH. At this time, the above-mentioned silica stone may be put into a slip (suspension) of a previously produced glaze and then mixed. In this case, the dissolution of the silica stone into the enamel glaze is further suppressed, and silver Is maintained in a state where it is easily ionized.

カビ効果が得られた。In the enamel thus formed, silver ions are selectively eluted from the silica stone, which takes a heterogeneous phase inside the enamel, onto the glass surface of the enamel under the influence of temperature and humidity. Therefore, an antibacterial and antifungal effect was obtained by the oligonagymy effect of the silver ions.

した。Example 3 A borosilicate glass in which a silver salt or a chromium salt is introduced into a glass composition is pulverized. This was added to a slip to produce a glaze. The glaze was thinly applied to the surface of the highly corrosion-resistant enamel, and then fired at 800 to 900 ° C. in the same manner as a normal enamel.

ジミー効果により抗菌防カビ能力が発揮される。In the antibacterial fungus enamel thus formed, the phase separation component is selectively melted under the influence of temperature and humidity due to the phase separation effect due to the abnormality of boric acid of the borosilicate glass fired on the surface. As a result, the silver network structure contained therein is also destroyed. Therefore, silver mixed in a phase-separated state is ionized, and the antibacterial and antifungal ability is exerted by the oligonagic effect of the silver ions.

Then, this was added to a mill additive, milled together with a frit in a mill to produce fine powder, and a glaze was produced as a suspension in which the fine powder was adjusted in concentration and pH. Then, the glaze was applied on a base metal plate, and then fired at 800 to 900 ° C. in the same manner as a normal enamel.

Since it can be formed by coating and baking in the same manner as conventional enamels, enamels can be easily manufactured, such as sinks such as vanities and sinks, or bathtubs and wall panels, which were often used because of their excellent characteristics. , Enamel products manufactured with this antibacterial and antifungal enamel have both the durableness of metal and the corrosion resistance and cleanliness of glass, as well as antibacterial and antifungal properties, especially when used around kitchens and bathrooms. Therefore, further improvement in hygiene will be achieved. In addition, since dirt on the surface can be easily removed by wiping, it can be more easily cleaned. In particular, in the case of using a glaze mixed with borosilicate glass, the phase separation glass is dissolved on the enamel layer together with silver ions due to an abnormality of boric acid due to the influence of temperature and humidity, so that the effect is more remarkable.

衛生面での向上も図られることとなる。As described above, since the antibacterial antifungal enamel of the present invention contains silver in the enamel or in the surface layer of the enamel, it is affected by other substances mixed at the same time, and the temperature and humidity are affected. Alternatively, silver ions having antibacterial and antifungal effects are eluted on the surface due to light. Therefore, propagation of bacteria and generation of mold can be effectively prevented with almost no maintenance. Therefore, it is suitable for use in a bathroom where mold is likely to occur at high temperature and humidity, and in a kitchen that tends to be dirty, and can be more easily cared for.
Improvements in hygiene will also be achieved.

する。In addition, the production method involves simply adding a silver-containing substance as a mill additive to the enamel glaze or directly applying the silver-containing substance onto the enamel and firing it, so that no new production equipment is required. Conventional enamel firing equipment can be used as it is.
Also, the number of production steps is almost the same as that of the conventional method if only a silver-containing substance is mixed as a mill additive. Therefore, an antibacterial and antifungal function can be added to the enamel by adding only necessary material costs, and an increase in manufacturing cost can be minimized. Furthermore, since the substance mixed into the glaze or applied and baked on the surface does not affect the properties of the enamel itself, it may impair the excellent properties of the enamel itself such as antifouling properties, heat resistance, and corrosion resistance. There are many excellent effects that there is not.
