Problems solved by technology

[0002] Many ceramic products are seen and used in daily life. Among them, ceramic ornaments are favored by people because of their various shapes, bright and rich colors, and profound meanings. Currently, ceramic ornaments on the market are usually made of clay after shaping. Glaze is sintered at a high temperature of 800-1200°C, and high-quality ceramic products require higher firing temperatures. If the glaze is not sintered at high temperature, it is dried at room temperature or at medium temperature. The obtained porcelain ornaments are prone to defects such as deformation, fragility, pigment fading, and peeling of the pigment layer. Therefore, providing a process for producing high-quality porcelain products at low temperature has great market significance

Abstract

The invention provides a manufacturing technology for a magnesium oxide dry pressing porcelain product. The technology comprises the following steps that magnesium oxide powder is adopted as raw materials to be subjected to dry pressing to obtain a porcelain body; tetraethoxysilane, polyglycol ether, ethyl alcohol, epoxy resin, sodium silicate, calcium silicate, titanium dioxide, water, dicyandiamide and a coloring agent are prepared into pigment, the pigment is adopted for coloring the porcelain body, finally, baking is performed under the temperature of 120-160 DEG C for 20-40 min, and the magnesium oxide dry pressing porcelain product is obtained. The magnesium oxide dry pressing porcelain product obtained through the manufacturing technology has various forms, bright and abundant colors, cannot fade after being placed for a long time, and has the certain corrosion resistance, the pigment layer is not likely to be peeled off, and high-quality artware can be manufactured.
