Problems solved by technology

[0002] Glaze is a continuous vitreous layer attached to the surface of the ceramic body, or a mixed layer of vitreous body and crystal. The main characteristics of enamel are that the glaze layer is uniform and thick, the glaze surface is moist, the water color is full, the texture is excellent, and the green body is glazed. , Generally, the glazing method of spraying glaze or dipping glaze combined with spraying glaze is mostly used, fired in a high-temperature kiln, and the atmosphere is mainly reduced flames, but the glazed surface made of existing enamel is resistant to high temperature, corrosion resistance and The mechanical ability is poor, the surface of the enamel is prone to cracks, the surface of the glaze is uneven, and it is easy to sag. At the same time, due to the uneven temperature during sintering, the glaze surface is blistered and the porcelain is deformed. The quality is not high, and there is an urgent need for glaze formulation Improve the quality of the glaze and improve the mechanical properties of the glaze

Abstract

The invention belongs to the field of porcelains and relates to porcelain glaze and a preparation method thereof. The porcelain glaze comprises 25 to 30 parts of potassium feldspar, 20 to 30 parts of bentonite, 5 to 8 parts of molybdenum trioxide, 5 to 10 parts of wollastonite, 0.5 to 0.8 parts of chromium oxide, 6 to 10 parts of quartz, 3 to 5 parts of dolomite, 5 to 8 parts of calcium carbonate, 4 to 8 parts of flint clay, 0.7 to 0.8 parts of sodium tripolyphosphate, and 1 to 3 parts of silicon carbide powder. The preparation method comprises pulverization, ball milling and blending. The porcelain product made by the preparation method does not contain lead, has high hardness of a glaze surface, high wear resistance and high strength, is not deformed easily, and has a good blank-glaze combination degree and good heat stability because of sintering at a high temperature.

Description

technical field [0001] The invention belongs to the field of porcelain, in particular to a porcelain glaze and a preparation method thereof. Background technique [0002] Glaze is a continuous vitreous layer attached to the surface of the ceramic body, or a mixed layer of vitreous body and crystal. The main features of enamel are that the glaze layer is uniform and rich, the glaze surface is moist, the water color is full, the texture is excellent, and the green body is glazed. , Generally, the glazing method of spraying or dipping and spraying is used, and it is fired in a high-temperature kiln. The atmosphere is mainly reducing flame, but the glaze made from the existing glaze has high temperature resistance, corrosion resistance and resistance The mechanical ability is poor, the glaze surface is prone to cracks, the glaze surface is uneven, and it is easy to sag. At the same time, due to the uneven temperature during sintering, the glaze surface is blistered, the porcelai...
