Low-temperature light-weight high-strength porcelainfor daily use and preparation method thereof

Abstract

The invention discloses low-temperature light-weight high-strength porcelain for daily use, which comprises the following raw materials in parts by weight: 2-5 parts of pottery clay, 5-8 parts of bentonite, 5-8 parts of sand and 4-9 parts of clay, and further comprises the following glaze raw materials in parts by weight: 10-15 parts of clam shell powder, 2-5 parts of bentonite, 10-12 parts of cordierite and 12-22 parts of albite. The preparation method of the glaze comprises the steps of putting the clam shell powder, the cordierite and the albite in parts by weight into liquid nitrogen, freezing for 20-24 hours, then taking out the clam shell powder, the cordierite and the albite, immediately adding the clam shell powder, the cordierite and the albite into a ball mill, carrying out dry grinding for 2-3 hours to obtain powder, carrying out constant-temperature stirring on the powder and the bentonite in parts by weight in a high-speed mixer at the temperature of 30-35 DEG C for 15-20 minutes to obtain a mixed material, and carrying out anaerobic calcination on the mixed material at the temperature of 100-120 DEG C to obtain the glaze. The porcelain for daily use obtained by the invention is light in weight and high in strength, and can be fired at low temperature.

Description

technical field [0001] The invention relates to the technical field of daily-use ceramics, in particular to a low-temperature light-weight high-strength daily-use porcelain and a preparation method thereof. Background technique [0002] Ceramics are widely used in our daily life due to their easy cleaning, good thermal stability, and stable chemical properties. However, ceramic products also have defects. Compared with light materials such as plastics, they are heavier. At the same time, their mechanical properties are relatively poor, and they are easy to be broken. These factors have limited the use of ceramic products in some occasions. Generally, ceramic products need to be fired at a higher temperature, and the higher temperature will oxidize the ceramic material, resulting in unpredictable color and performance of the ceramic product. Contents of the invention [0003] Based on the above defects, the present invention provides a low-temperature, light, high-strength...
