Description
Technical field
The present invention relates to a kind of enamel, particularly have the enamel of anti-microbial effect.
Background technology
The history in existing thousand of inorganic enamel material, it is a kind of conventional art, its technical process generally is the prescription according to design, choose raw material (natural mineral, chemical materials etc.), through weighing, mix the back and in High-temp. kiln (1200 ℃～1350 ℃), be melt into glassy mass, again through shrend or compressing tablet, make the glaze piece, add an amount of mill addition with the glaze piece, as: clay, dielectric substance, pigment and water etc. are worn into certain fineness together in ball mill, make glaze slip and be coated in and handled on the various metallic surfaces of cleaning in advance, under 750 ℃～900 ℃ temperature, be fused into level and smooth, glossiness enamel layer.But the surface of this common enamel material, may adsorb various harmful bacteriums and mould, at this problem, people wish to produce the enamel with anti-microbial effect, the interpolation antiseptic-germicide is a kind of method wherein, the employed antiseptic-germicide of people is organic antibacterial agent and inorganic antiseptic now, wherein organic antibacterial agent is thermo-labile, the temperature that is suitable for the course of processing is lower than the situation of 300 degree, be not suitable for enamelware pyritous complete processing, and if after inorganic antiseptic is melt into the porcelain piece according to conventional enamel frit makeing method and material commonly used together, because redox, effects such as volatilization or generation silicate, the porcelain facing color and luster is unstable or do not play anti-microbial effect, wear into glaze slip if mix, then porcelain facing tarnish, crude, neither attractive in appearance, anti-microbial effect is also little.
Summary of the invention
At the shortcoming that above-mentioned prior art exists, the object of the present invention is to provide a kind ofly can keep the gloss on enamel layer surface, smooth, color and luster, can guarantee that again antiseptic-germicide can be present in the enamel that plays anti-microbial effect in the enamel coating snugly.The present invention also provides the preparation method of this antibacterial enamel.
