Problems solved by technology

The existing anti-counterfeiting technology on the market is to add fluorescent powder to the glaze, the disadvantages are: it is not resistant to high temperature, and the shelf life is short; therefore, it is technically necessary to develop a permanent anti-counterfeiting technology. Time use will not easily lose its invisible anti-counterfeiting effect

Embodiment 1

[0025] 1): Mix glaze powder of any color with anti-counterfeit powder (Youpin Bao Technology (Technology) Beijing Co., Ltd.) in a ratio of 100:0.3 to prepare anti-counterfeit glaze powder;

[0026] 2): In step 1), put the mixed anti-counterfeit glaze powder into a ball mill tank, add 30% water of the total weight, and continue ball milling for more than 24 hours to obtain a water glaze;

[0027] 3): The water glaze obtained in step 2) is filtered with a 200-mesh sieve to obtain a flow rate of 11m / s and a specific gravity of 130g / cm 3 water glaze;

[0028] 4): After the step 3) is completed, immerse the ceramic body in the water glaze to absorb the glaze for 3 seconds, take it out, and wipe the bottom of the body clean;

[0029] 5): The glaze base obtained in step 4) is subjected to high-temperature reduction firing for 9 hours at a firing temperature of 780° C., and is kept for 0.5 hours according to the actual maximum temperature of the water glaze to obtain a finished produ...

Embodiment 2

[0032] 1): Mix the glaze powder of any color with the anti-counterfeit powder according to the ratio of 100:1 to prepare the anti-counterfeit glaze powder;

[0033] 2): In step 1), put the mixed anti-counterfeit glaze powder into a ball mill jar, add 40% water of the total weight, and continue ball milling for more than 24 hours to obtain a water glaze;

[0034] 3): The water glaze obtained in step 2) is filtered with a 200-mesh sieve to obtain a flow rate of 13m / s and a specific gravity of 140g / cm 3 water glaze;

[0035] 4): After the step 3) is completed, immerse the ceramic green body in the water glaze to absorb the glaze for 4 seconds, take it out, and wipe the bottom of the green body clean;

[0036] 5): The glaze blank obtained in step 4) is subjected to high-temperature reduction firing for 10 hours at a firing temperature of 1100° C., and is kept for 1 hour according to the actual maximum temperature of the water glaze to obtain a finished product.

Embodiment 3

[0039] 1): Mix any color glaze powder and anti-counterfeit powder according to the ratio of 100:1.5 to prepare anti-counterfeit glaze powder;

[0040] 2): In step 1), put the mixed anti-counterfeit glaze powder into a ball mill tank, add 50% water of the total weight, and continue ball milling for more than 24 hours to obtain a water glaze;

[0041] 3): The water glaze obtained in step 2) is filtered with a 200-mesh sieve to obtain a flow rate of 15m / s and a specific gravity of 150g / cm 3 water glaze;

[0042] 4): After the step 3) is completed, immerse the ceramic body in the water glaze to absorb the glaze for 5 seconds, take it out, and wipe the bottom of the body;

[0043] 5): The glaze base obtained in step 4) is subjected to high-temperature reduction firing for 12 hours at a firing temperature of 1320° C., and is kept for 1.5 hours according to the actual maximum temperature of the water glaze to obtain a finished product.

Abstract

The invention provides a ceramic firing method for a ceramic glaze with invisible anti-counterfeiting function, comprising: 1) mixing glaze powder of any color and anti-counterfeiting powder in a mass ratio of 100:0.3-1.5 to prepare anti-counterfeiting glaze powder; 2) In step 1) put the mixed anti-counterfeiting glaze powder into the ball mill jar, add 30%-50% water of the total weight, and perform continuous ball milling to obtain a water glaze; 3) the water glaze obtained in step 2) uses 200-50% water 500 mesh sieve filter; 4) after the completion of step 3), immerse the ceramic chinaware in the water glaze to absorb glaze to obtain a glaze body, and wipe the body clean; 5) carry out high temperature for the glaze body obtained in step 4). Reduction firing to obtain the finished product. The invention develops a permanent physical anti-counterfeiting technology, which adopts high-temperature-resistant glaze and is fired into ceramics, which will not easily lose its invisible anti-counterfeiting effect after long-term use.

Description

technical field [0001] The invention relates to a ceramic firing method of a ceramic glaze with an invisible anti-counterfeiting function, which belongs to the field of ceramics. [0002] technical background [0003] In the existing pottery field, there is no anti-counterfeit ceramic glaze on the market. The existing anti-counterfeiting technology on the market is to add fluorescent powder to the glaze, the disadvantages are: it is not resistant to high temperature, and the shelf life is short; therefore, it is technically necessary to develop a permanent anti-counterfeiting technology. Time use will not easily lose its invisible anti-counterfeiting effect. Contents of the invention [0004] In view of the above technical problems, the inventor provides a firing method of ceramic glaze with invisible anti-counterfeiting function, which includes the following steps: [0005] 1) Mix the glaze powder of any color with the anti-counterfeit powder according to the ratio of 10...
