Problems solved by technology

[0002] Many ceramic products are seen and used in daily life. Among them, ceramic ornaments are widely loved by people because of their various shapes, bright colors, and rich and profound meanings. The high-quality ceramic ornaments on the market are usually made of clay after shaping. Glazed, made by sintering at 800-1200°C, without sintering, the porcelain ornaments that are air-dried or oven-dried at room temperature have low wear resistance, are easy to fade for a long time, and the pigment layer is easy to peel off. Therefore, It is of great economic significance to provide a ceramic product that is not fired at high temperature and has certain wear resistance, thermal stability and water resistance

Abstract

The invention provides a process for producing dry pressed porcelain products. The process comprises the steps of: mixing magnesium oxide with sodium silicate, performing grinding after adding ethanol, then performing drying at 50-55 DEG C to obtain a blank material, shaping the blank material under a pressure condition of 620-800 MPa to obtain a green body; preparing a pigment from guar gum, water, waterborne polyurethane resin, gypsum, pyrophyllite powder, rutile titanium dioxide, a coloring agent and sodium silicate; and coloring the green body with the pigment, performing air drying and firing to obtain the dry pressed porcelain product. The dry pressed porcelain product provided by the invention has various forms and rich and colorful colors, does not fade after a long time, is brightand new, and has certain wear resistance, the pigment layer is not easily peeled off, and the dry pressed porcelain product can be manufactured into a high-quality handicraft.
