It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of the invention.
The invention provides a preparation method of a ceramic tile with a sunken glaze effect, which comprises the following steps:
A. preparing a green brick: the green brick is prepared from conventional raw materials. The raw materials are subjected to ball milling mixing, spray granulation and then compression molding through a press, and the green brick is dried through a drying kiln to remove part of water.
B. Applying base glaze: spraying or sprinkling the ground glaze on the surface of the green brick; the ground coat comprises the following components in percentage by mass: 59.06% SiO2、7.36％TiO2、8.71％Al2O3、2.89％MgO、15.69％CaO、1.12％Na2O、2.19％K2O、0.01％SrO、0.14％ZrO20.02 percent of BaO and 0.05 percent of ZnO, and the balance is loss on ignition. The glazing amount of the ground coat is 350-375 g/m2. The ground glaze contains TiO with good covering power and high whiteness and brightness2The color of the green brick can be covered. SiO in the above ground coat2Is higher in content of Al2O3Has a low content of (A) so that the melting temperature is low, and is compatible with fluxing alkaliThe metal matching is favorable for forming a large amount of glass phase which permeates into the interior of the green brick to fill and level the surface of the green brick and pave the subsequent application of overglaze.
C. Spraying or sprinkling a cover glaze on the surface of the ground glaze; the overglaze comprises the following components in percentage by mass: 47% -52% of SiO2、13％～17％Al2O3、1％～2％MgO、7％～10％CaO、1％～2％Na2O、2％～4％K2O、0.5％～2％SrO、1％～3％ZrO26 to 10 percent of BaO and 7 to 10 percent of ZnO. The overglaze also contains 100 parts of solid matter, 3-5 parts of zirconium silicate, 0.1-0.3 part of sodium carboxymethyl cellulose, 0.2-0.5 part of sodium tripolyphosphate and 36-40 parts of water by weight.

The defoaming agent is octyl phenol polyoxyethylene ether; when the deep ink is prepared, all components in the deep ink need to be stirred and mixed uniformly, and a trace amount of defoaming agent is added to eliminate foam generated in the stirring process and reduce the surface tension. The anti-settling agent is oily white carbon black.
E. Spraying or sprinkling a protective glaze which is mutually repulsive with the oily deep-drawing ink on the surface of the oily deep-drawing ink; the protective glaze comprises the following components in percentage by mass: 47% -52% of SiO2、13％～17％Al2O3、1％～2％MgO、8％～11％CaO、1％～2％Na2O、2％～4％K2O、0％～1.5％SrO、0％～1％ZrO28 to 10 percent of BaO and 7 to 10 percent of ZnO. Similarly, the protective glaze also contains sodium carboxymethyl cellulose, sodium tripolyphosphate and water. The solid matter content of the protective glaze is 100 parts by weight, the sodium carboxymethylcellulose is 0.1-0.3 part by weight, the sodium tripolyphosphate is 0.2-0.5 part by weight, and the water is 36-40 parts by weight. The reduced dry weight of the protective glaze is about 47 g.
The protective glaze is transparent matte glaze and has good permeability. Similarly, the protective glaze is water-based glaze slip which is mutually exclusive with the oily deep-drawing ink, most of the protective glaze is discharged by the oily deep-drawing ink, and a small part of the protective glaze is spread on the oily deep-drawing ink, so that a thin protective glaze covers a sunken part formed by the oily deep-drawing ink, and the sunken part achieves the antifouling effect.
The glazing amount of the protective glaze is 350-375 g/m2. The glazing amount enables the protective glaze layer on the brick surface to have moderate thickness, good permeability and good antifouling effect. And the excessive glazing amount can lead the falling to be covered with excessive protective glaze, thus leading the falling to become shallow and narrow; the glaze layer is reduced in permeability due to too small glazing amount, the color generation effect of the printing ink is influenced, the glaze layer is thinned, the glass phase is reduced, and the antifouling performance of the glaze surface is reduced.
