High-temperature environment-friendly colored glaze

Abstract

The invention mainly relates to the technical field of ceramic glaze processing, and discloses a high-temperature environment-friendly colored glaze. The high-temperature environment-friendly colored glaze is prepared from the following raw materials: silicon dioxide, magnesium oxide, iron nitride, niobium pentoxide, vanadium boride, silicon nitride, aluminum nitride, zirconium oxide, cerium dioxide, hornblende, hard clay, table salt and pigments. A glaze surface becomes flat and smooth through short-time high-temperature burning and expansion coefficient matching, energy is saved, and no lead is dissolved out; the high-temperature environment-friendly colored glaze is safe, nontoxic and environment-friendly, and the production cost is lower by about 12.6 percent; the raw materials are mixed after being subjected to one-time ball milling, and are then subjected to repeated melting, quenching and ball milling, so that the colored glaze is fine and smooth in texture; the table salt is added after primary quenching, so that the high-temperature environment-friendly colored glaze is convenient to be added with water and mixed uniformly in use, and has the advantages of fineness, high fluidity, uniform glazing and smooth texture; the pigments are added after second melting, and high-temperature calcination is performed, so that the stability of the colored glaze and the pigments are enhanced, and the colored glaze is gorgeous, uniform in brightness and colorfast.

Description

technical field [0001] The invention mainly relates to the technical field of ceramic glaze processing, in particular to a high-temperature environment-friendly colored glaze. Background technique [0002] Glaze is a kind of silicate. The glaze applied on ceramics is generally made of quartz, feldspar, and clay. After grinding and adding water, it is coated on the surface of the green body and melted by roasting at a certain temperature. The temperature drops When forming a thin glassy layer on the surface of ceramics, it can increase the mechanical strength, thermal stability, dielectric strength of the ceramics and prevent the erosion of liquids and gases. effect. [0003] However, at present, ceramic glazes are generally fired at high temperatures. The temperature is higher than 1250 ° C, and some are even above 1400 ° C. The energy cost of firing accounts for a large proportion of the production cost, accounting for 20-30% in foreign countries. my country accounts for m...

[0003] However, at present, ceramic glazes are generally fired at high temperatures. The temperature is higher than 1250 ° C, and some are even above 1400 ° C. The energy cost of firing accounts for a large proportion of the production cost. In my country, it accounts for more than 30%, and most of the ceramic glazes are filled with lead, which will cause great harm to the human body in the process of preparation and use. Therefore, reducing energy consumption during high-temperature firing is an urgent need at present.
