High-temperature domestic porcelain metallic bright glaze and product decorated by same

Abstract

The invention relates to a high-temperature domestic porcelain metallic bright glaze and a product decorated by the same. The bright glaze produced by using natural mineral raw materials and industrial pure raw materials comprises the following materials by weight percent: 10-25 percent of potassium feldspar, 10-30 percent of albite, 0-35 percent of quartz, 0-10 percent of barium carbonate, 0-10 percent of wollastonite, 0-10 percent of kaolin, 0-5 percent of zinc oxide, 1-10 percent of aluminum oxide, 1-10 percent of bone ash, 1-5 percent of purple clay and 10-35 percent of ferric phosphate, and the glaze is obtained by mixing, ball-milling and screening the raw materials. The fabrication technology of the glaze is basically the same as the common porcelain glaze, the cost is low, not only can the pure color be guaranteed through redesigning of the formula of the glaze, but also the burning temperature of the glaze is increased to 1380 DGE C, so that the decoration effect of domestic porcelain is greatly enriched, and the high-temperature domestic porcelain metallic bright glaze has wide application prospect.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials (ceramics), and in particular relates to a high-temperature daily-use porcelain metallic luster glaze and a product decorated therewith. Background technique [0002] Metallic luster decorative glaze is a decorative glaze with metallic luster effect, such as gold, silver, golden red, black and so on. At present, gold water is mainly used to prepare metallic luster decoration effect in daily-use porcelain, which has high cost, and the metal part is easy to peel off during use. In addition, the metallic luster decorative glaze in daily-use porcelain can also be fired by making glaze. The preparation methods described in Chinese patents CN101244949 and CN103387420 can obtain glazed surfaces with metallic luster, but one of them contains a large amount of heavy metals Mn, Sn, V, Pb, etc. In the process of using daily-use porcelain, metal ions are easy to dissolve, which is harmful to ...

AI Technical Summary

Problems solved by technology

Therefore, the preparation method of high-temperature metallic luster glaze suitable for daily-use ceramics is currently the bottleneck in the production of daily-use ceramics, which seriously restricts the decorative effect of daily-use ceramics.
