Detailed Description

Then, a primer is applied to the blank. The primer glaze is not particularly limited, and primer glazes known in the art can be used.
The mode of applying the primer is not particularly required, and a method for preparing glaze slip which is conventional in the field is adopted. The glaze spraying can be performed by adopting an ink-jet printer.
The marble pattern is printed on the ground coat layer, and can be printed by a digital ink-jet printer. The ceramic ink used may be blue, brown, orange, lemon yellow, black, red, etc.
(2) And (3) screen printing Shi Seyou on the surface of the ceramic tile blank obtained in the step (1).
And (3) applying colored glaze on the surface of the green body after ink-jet printing through screen printing, and selecting colored glaze with different colors according to the requirement, wherein the screen printing method adopts a conventional method in the field. By applying colored glaze, the color can be further enriched.
(3) And (3) locally positioning and distributing the colorful dry granular glaze on the surface of the colored glaze.
The method is characterized in that the method is used for fully distributing the magical color glaze, and the method adopts local distribution to highlight the magical color effect, so that the problems of flickering and unobtrusive magical color effect caused by low consumption of magical color dry materials in the full distribution are avoided.
The multicolor dry grain glaze adopted in the scheme of the invention is formed by mixing 40-50 parts of transparent dry grains, 20-30 parts of flickering dry grains, 20-30 parts of stamp-pad ink and 10-15 parts of printing paste. The transparent dry grain composition is SiO2 55-60％、Al2O3 5.5-8.5％、Fe2O3 0-0.3％、CaO 10-15％、MgO 0.2-0.3％、BaO 1.5-4％、ZnO 8-15％、K2O 5-9％、Na2O 0-3％、ZrO2 0.2-0.5％、TiO2 0-1.5％; and the scintillating dry grain composition is SiO 2 30-40％、ZrO2 60-70％、Al2O3 0-1％、CaO 0-1％、TiO2 -1%.
Preferably, in the multicolor dry grain glaze, transparent dry grains are in a mass ratio of (1:0.4-0.6), so that the finally obtained ceramic tile has good multicolor effect, good breaking modulus and strong shock resistance.
The stamp-pad ink and the stamp-pad paste are stamp-pad ink and stamp-pad paste raw materials commonly used in the ceramic field, preferably the stamp-pad ink viscosity is 1000-1200 mpa.S, and the stamp-pad paste viscosity is 7000-7500 mpa.S.
Preferably, the distribution amount of the multicolor dry granular glaze is 1-1.2kg/m 2, and the thickness is 0.75-1.5mm.
Preferably, the transparent dry particle size is 37-75 μm, and the flash dry particle size is 150-250 μm.
The proportion of scintillating dry materials in the multicolor dry particle glaze can be increased by adopting the local fixed-point cloth-applied multicolor dry particle glaze, and in the multicolor dry particle glaze of the scheme of the invention, the melting point of the transparent dry particles is lower by optimizing the components of the transparent dry gift and the scintillating dry particles, and the scintillating dry particles with high melting point are firstly fused and wrapped in the firing process, so that the wrapped scintillating dry particles in the glaze layer can be stacked layer by layer to form a refraction layer of light rays, thereby forming more vivid multicolor effect.
(4) And (3) spraying protective glaze on the surface of the ceramic tile blank obtained in the step (3).
Through spraying the protective glaze, the ceramic tile has a certain thickness on the glaze layer after firing, and can be fully polished, so that the tile surface is smooth and the color-changing layer under the glaze is not damaged. The polishing agent not only can provide higher cutting amount for polishing the brick surface, but also does not influence the antifouling performance of the brick surface. And after polishing and waxing, the brick surface is ground flat, and as the brick surface has higher luminosity, better flatness and transparent glaze, light can well irradiate the scintillation dry particles in the glaze, and the scintillation dry particles in a plurality of numbers are refracted, so that a vivid multicolor gradual change effect is generated.
The protective glaze is slurry formed by dispersing protective glaze powder in water so as to facilitate the spraying of the glaze. Commonly used dispersants are sodium tripolyphosphate, sodium methylcellulose, and the like.

In one embodiment of the invention, the protective glaze is formed by ball milling 66.3 parts of protective glaze powder, 33.2 parts of clear water, 0.3 part of sodium tripolyphosphate and 0.2 part of sodium methylcellulose.
(5) Firing the green bricks obtained in the step (4) to form;
and (5) sintering the blank in a kiln. The firing temperature is 1185-1225 ℃, the firing time is 45-60min, and the undertemperature or the overshort time can easily cause incomplete melting vitrification of the glazed surface of the ceramic tile and influence the permeability of the surface of the ceramic tile.
(6) Polishing and waxing the green bricks obtained in the step (5).
Polishing and waxing can be carried out after the sintering. For example, the surface of the ceramic tile is polished by the diamond brush disc rotating at high speed, so that the surface of the ceramic tile has marble-like texture and fantasy effect, and the ceramic tile can be polished completely, so that the surface has higher glossiness and flatness. Full polishing refers to the complete polishing of a surface, with a relatively thick polishing thickness, for example, in the range of 0.1-0.4mm, to polish the surface to a specular effect. Through full polishing, a part of the polishing agent can be thrown off, and has certain glossiness, such as 25-35 degrees. Or may be semi-polished. Semi-polishing refers to polishing the surface to increase the glossiness.
Preferably, the substrate brick surface luminosity after polishing is between 70 and 80 degrees, and the substrate brick surface luminosity after waxing is between 90 and 100 degrees, so that the brick surface is smooth and transparent, and the multicolor effect is better locally displayed under the irradiation of light.
Preferably, the polishing process comprises the steps of adopting 10 groups of 400-mesh elastic grinding blocks, 10 groups of 600-mesh elastic grinding blocks and pressure of 4kg, then adopting 10 groups of 800-mesh elastic grinding blocks, 10 groups of 1000-mesh elastic modules and finally adopting 20 groups of 240-mesh sponge polishing, wherein the pressure is 2 kg. The waxing process can be a conventional ceramic polishing wax, such as a double-benefit polishing wax in an embodiment of the invention, and the dripping amount is 12-15g/m 2.

The polishing process comprises the steps of adopting 10 groups of 400-mesh elastic grinding blocks, 10 groups of 600-mesh elastic grinding blocks and the pressure of 4kg, then adopting 10 groups of 800-mesh elastic grinding blocks, 10 groups of 1000-mesh elastic modules and the pressure of 2kg, and finally adopting 20 groups of 240-mesh sponge polishing with the pressure of 0.5kg & lt 2 & gt. The surface luminosity of the polished substrate brick is 75 degrees, then the double-benefit medium polishing wax is used for waxing, the dripping amount is 12g/m 2, and the surface luminosity of the substrate brick after waxing is 92 degrees.
Finally, the prepared magical marble tile has a smooth and transparent tile surface, and a local magical effect and a breaking modulus of 46.1mpa under the irradiation of light.
Comparative example 1
The difference from example 1 is that the amounts of the components in the magical color dry grain glaze are different, and the transparent dry grain is scintillation dry grain=3:1 according to the mass ratio, and the rest are the same. The resulting tile had a modulus of rupture of 46.7mpa, but the fantasy effect was not apparent due to the small amount of flash dry particles accumulated in the glaze.
Comparative example 2
The difference from example 1 is that the amounts of the components in the magical color dry grain glaze are different, and the transparent dry grain is scintillation dry grain=5:7 according to the mass ratio, and the rest are the same. The breaking modulus of the finally obtained ceramic tile is 41.6mpa, and the flash dry particles are excessively accumulated in the glaze layer and cannot be completely wrapped in the firing process, so that the inside of the glaze layer is cracked, the surface effect is affected, and the brick surface performance is reduced.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
