Detailed Description

The present invention is further illustrated by the following examples, which are to be understood as merely illustrative and not restrictive. Unless otherwise specified, each percentage means a mass percentage.

The following describes an exemplary method for preparing the marble ceramic tile with the digital stereoscopic effect and the golden texture with reference to fig. 1.

Firstly, pressing and forming green body powder to form a green brick. The green brick can be formed by dry pressing using a press. The composition of the green body powder is not limited, and the conventional ceramic tile green body powder in the field can be adopted. For example, the chemical composition of the green body powder comprises, in mass percent, SiO₂：60.0～70.0％、Al₂O₃：19.0～25.0％、Fe₂O₃：0.5～1.5％、TiO₂：0.2～0.5％、CaO：0.2～0.8％、MgO：0.3～0.8％、K₂O：2.0～4.0％、Na₂O: 1.5-3.5%, loss on ignition: 4.0 to 6.0 percent.

And drying the green brick. The drying time can be 1-1.5 h. And controlling the moisture of the dried green brick to be 0.3-0.5 wt%.

And applying base glaze on the surface of the dried green brick. The ground glaze is applied to improve the texture of the glaze and reduce pinholes and miliaria of the glaze. The ground coat can be applied by spraying glaze.

In some embodiments, the chemical composition of the ground glaze may include: by mass percent, SiO₂：55～60％、Al₂O₃：21～24％、Fe₂O₃：0.16～0.46％、TiO₂：0.15～0.25％、CaO：0.1～0.3％、MgO：0.1～0.3％、K₂O：4.0～5.0％、Na₂O：2.0～3.0％、ZrO₂: 6.0-10.0%, loss on ignition: 3.0 to 4.0 percent.

The specific gravity of the ground coat can be 1.40-1.45, and the glazing amount can be 400-550 g/m²。

And (4) ink-jet printing patterns on the surface of the green brick after the ground glaze is applied. The color and pattern of the inkjet printed pattern vary according to the layout effect.

And (4) positioning and distributing glue on the surface of the green brick after ink-jet printing. The glue can be printed by a digital glue ink jet. The glue mainly plays a role in bonding. The gray scale of the glue pattern can be 20% -100%. Glue patterns with different gray scales correspond to different gold dry particle application amounts. The application amount of the glue patterns and the golden dry particles can be adjusted according to the actual effect of the layout design. If the gray level of the glue pattern is less than 20%, the glue is not firm in fixation of dry particles, the phenomenon that the dry particles to be fixed are taken away easily occurs, in addition, the dry particles with a small amount of glue adhered to the surface can enter a circulating system of a dry particle machine, the dry particle mobility is easy to deteriorate along with the lapse of time, and the phenomenon of uneven blanking occurs. In some embodiments, the desired portions of the pattern are selected in advance, depending on the pattern design, and the glue forms a glue pattern on the tile face by printing the glue with a digital glue jet. And the state of the spray head can be conveniently observed by adding pigment into the glue.

And golden dry particles are distributed on the surface of the green brick after the glue is distributed. For example, golden dry granules are distributed on the surface of a green brick by a digital glue dry granule machine, and the dry granules which are not adhered and fixed by the glue are pumped away and recycled by an exhaust fan. And in the glue pattern corresponding areas with different gray scales, the remained dry particles are pumped away by an exhaust fan to form certain pattern textures. In addition, glue patterns with different gray scales correspond to different golden dry particlesA fixed amount, and thus exhibits a concavo-convex effect due to the accumulation of the gold dry particles in at least a partial region. In addition, the thickness and the gray scale of the pattern (line part) can be adjusted according to the actual layout effect. If the gray level of the glue pattern is too high, the amount of the adhered golden dry particles is relatively large, and the glaze surface of the part of the burnt golden dry particles is relatively convex. If the gray scale of the glue pattern is too low, the adhesion amount of the golden dry particles is too small, so that the golden effect appears scattered and not coherent and natural enough, as shown in comparative example 1. The research shows that when the double-channel glue is adopted, the gray level is 45-55%, and the quantity of the adhered dry particles is 200-300 g/m²The effect is optimal. If the gray level of the double-channel glue is higher than 55%, the glaze stripping phenomenon can occur. The reason is that the glue can form a film prematurely in the drying process, so that the blank body is prevented from draining water, and when the water vapor of the blank body is too much, the film can be broken to cause the phenomenon of stripping. If the gray level of the double-channel glue is lower than 45%, the amount of the adhered golden dry particles is small, so that part of the golden dry particles are not firmly adhered to enter a circulating system of the glue dry particle machine, and the part of the golden dry particles adhered with a small amount of glue is easy to cause the poor flowability of the dry particles along with the time, so that the condition of uneven blanking is caused.

The chemical composition of the golden dry particles can comprise: by mass percent, SiO₂：33.0～36.0％、Al₂O₃：12.0～15.0％、Fe₂O₃：15.0～20.0％、TiO₂：0.15～1.50％、CaO：2.0～4.0％、MgO：0.1～0.5％、K₂O：0.3～1.0％、Na₂O：5.0～10.0％、P₂O₅：16.0～22.0％、ZnO：1.0～2.0％、Cr₂O₃: 0.50-1.50%, loss on ignition: 0.1 to 0.3 percent.

The golden dry granules comprise the following raw materials: 45-50% of albite, 30-35% of iron phosphate, 5-10% of calcium phosphate, 3-10% of silicon tripolyphosphate, 5-10% of kaolin, 1-2% of zinc oxide, 1-3% of ferrochrome brown and 1-3% of ferrotitanium yellow in percentage by mass. In the formula, iron chromium brown and ferrotitanium yellow are introduced as seed crystals, and zinc oxide plays roles in crystallization assistance and fluxing, so that a golden effect is realized.

In some embodiments, the method of preparing the gold-colored dry granules comprises: weighing the raw materials according to the formula ratio, putting the raw materials into a mixer, uniformly mixing, adding the uniformly mixed raw materials into a smelting furnace, melting the raw materials into liquid at a high temperature of 1500-1600 ℃, vertically flowing into water at a temperature of 20-70 ℃, and quenching to form a fusion cake. And (4) after the water content of the fusion cake is filtered, putting the fusion cake into a roll crusher for crushing and screening to obtain the golden dry particles with the required particle size distribution. The grain diameter of the golden dry particles is 40-150 meshes. And (3) circularly feeding the particles with the mesh number of less than 40 into a double-roller machine for circular crushing, and feeding the particles with the mesh number of more than 150 into a smelting furnace as a raw material for recycling.

The golden dry particles are particles with certain particle size distribution obtained after high-temperature melting, crushing and screening, and organic matters and carbonate in the golden dry particles are volatilized. In addition, after the pattern is printed by ink jet, the preparation method of the invention adopts a mode of spraying glue by a digital glue ink jet machine and distributing dry particles by a digital glue dry particle machine, and the three-dimensional effect and the golden texture are realized by adhering the golden dry particles by the glue gray scale and the texture of a design effect net (namely a pattern design layout).

And (4) fully polishing glaze on the surface of the green brick coated with the golden dry particles. The purpose of applying the full glaze after the golden dry particles are distributed is to ensure the antifouling effect of the part without the golden dry particles and the requirement of polishing processing at the later stage. The fully polished glaze can be a transparent fully polished glaze. The full-polishing glaze can adopt conventional full-polishing glaze. In some embodiments, the chemical composition of the fully polished glaze may include: by mass percent, SiO₂：43.0～50.0％、Al₂O₃：13.0～16.0％、Fe₂O₃：0.1～0.5％、TiO₂：0.1～0.3％、CaO：7.0～9.0％、MgO：3.5～4.5％、K₂O：3.5～4.5％、Na₂O: 1.5-2.5%, ZnO: 3.0-5.0%, BaO: 7.0-12.0% loss on ignition: 6.0 to 9.0 percent.

The application mode of the full-polishing glaze can be glaze pouring. The specific gravity of the full-polished glaze is 1.76-1.81, and the glazing amount is 550-650 g/m²。

Because polishing is needed finally, the golden dry particles and the full polishing are carried outThe portion of the glaze overlay was discarded, completely exposing the textured portion of the gold dry grain. The fully-polished glaze plays a role in adhesion in the firing process, so that the golden dry particles can be prevented from being pumped away by a kiln, and the close combination between the fired golden dry particles and the fully-polished glaze can also be ensured. Meanwhile, in order to avoid the phenomenon of stripping, the water can be smoothly discharged in the drying process by controlling the using amount of the digital glue and the using amount of the full-polished glaze. In some embodiments, the amount of the glue is 12-60 g/m²。

And drying the green brick after the full glaze polishing. The drying temperature can be 100-150 ℃, and the water content of the dried green brick is controlled within 0.9 wt%. The drying mode can be electric drying or hot air drying oven drying.

And sintering the dried green brick. The maximum firing temperature can be 1210-1230 ℃, and the firing period can be 60-70 minutes.

Polishing the sintered ceramic tile, and edging and grading to obtain the marble ceramic tile with golden texture.
