Technical Field

[0001] The invention relates to the technical field of sanitary ceramics, in particular to a method for preparing a zirconium silicate composite material for matte glaze of sanitary ceramics. Background Art

[0002] Sanitary ceramics are glazed ceramic products used in bathrooms, kitchens, laboratories and other places, also known as sanitary ware. According to the material of the product, there are four types: clinker pottery (water absorption rate less than 18%), fine pottery (water absorption rate less than 12%), semi-porcelain (water absorption rate less than 5%) and porcelain (water absorption rate less than 0.5%). Among them, the performance of porcelain materials is the best. Clinker pottery is used to make large appliances such as vertical urinals and bathtubs, and the other three are used to make medium and small appliances. Sanitary ceramics in various countries are made of different materials according to their use environment conditions.

[0003] Sanitary ceramics are baked with various materials, and matte glaze for sanitary ceramics is the material of sanitary ceramics. For example, a Chinese patent discloses a method for preparing blue gradient glaze sanitary ceramics, and the patent number is: CN107814488B. The glaze consists of basic glaze, silicon dioxide, dolomite, zinc oxide, zirconium silicate, glaze feldspar powder and vanadium zirconium blue. Two glaze slurries A and glaze slurry B with different vanadium zirconium blue contents are prepared from the above glazes, and the glaze slurry A and glaze slurry B are sprayed on the surface of the sanitary ceramic white blank in succession, wherein the spraying amount of glaze slurry A gradually decreases from the top to the bottom of the white blank spraying area, while the spraying amount of glaze slurry B gradually increases, and then the glazed white blank is fired in a tunnel kiln at 1202-1250°C for 15-18h to obtain a blue gradient glaze sanitary ceramic product. The obtained product meets the processing and use performance requirements of sanitary ceramics, has good gradient effect, excellent decorative effect, and meets the needs of personalized bathroom.
