Abstract

The invention provides a ceramic with an invisible anti-counterfeiting function. A method comprises the steps of: 1) mixing high-temperature porcelain clay and anti-counterfeit powder in a ratio of 100 to (0.3 to 1.5) to obtain anti-counterfeiting porcelain clay; 2) mixing mixture of the anti-counterfeiting porcelain clay obtained in step 1), adding water with a mass fraction of 8% to 12%, water glass with a mass fraction of 0.3% to 0.4%, and American water with a mass fraction 0.1% to 0.3%, mixing for 1 to 3 hours, using a 120 to 180 mesh filter screen to filter, and producing slurry with a flow rate of 25m/s to 30m/s and a specific gravity of 160g/cm<3> to 180g/cm<3>; 3) pouring the slurry obtained in step 2) into a plaster mold, waiting for the slurry to solidify, and taking out an unfired brick; 4) after the step 3) is finished, drying and repairing the unfired brick at room temperature; 5) putting the unfired brick cleaned in the step 4) in a kiln for biscuit firing to obtain a biscuit; 6) glazing the biscuit prepared in step 5), and conducting high-temperature reduction and firing on a glazed body to obtain a finished product. The invention provides a permanent anti-counterfeiting technology ceramic, the ceramic is heat-resistant, and can satisfy industrial needs.

Description

technical field [0001] The invention relates to a ceramic with an invisible anti-counterfeiting function, which belongs to the field of ceramics. technical background [0002] In the existing ceramic field, ceramic products with invisible anti-counterfeiting function have not been seen in the market. The existing anti-counterfeiting technology on the market is a digital anti-counterfeiting method with a chip attached to the surface of the product, which is easy to damage and counterfeit, so the anti-counterfeiting effect is not good. . The invisible anti-counterfeiting function provided by the invention is a physical anti-counterfeiting method, which cannot be copied or destroyed. Contents of the invention [0003] In view of the above technical problems, the inventor provides a ceramic with an invisible anti-counterfeiting function, wherein the ceramic clay is prepared by the following steps: [0004] 1) Mix high-temperature china clay and anti-counterfeit powder accord...
