The overglaze and the protective glaze in this embodiment are both conventional overglaze and protective glaze, and the spraying process or the glaze spraying process is both conventional processes, and are not described herein again.
And C, printing a pattern layer with a slip-resistant effect on the green body coated with the protective glaze by a roller to obtain a primary finished product of the glazed tile. The pattern layer is formed by printing and dyeing printing fancy glaze through a rubber roll, and the printing fancy glaze comprises 40-60 parts by weight of high-temperature protrusion powder, 40-60 parts by weight of anti-slip glaze powder and 60-80 parts by weight of printing paste. The printing paste is used for adjusting the viscosity and the fluidity of the printing fancy glaze, so that the high-temperature bump powder and the anti-slip glaze powder have certain viscosity and fluidity, and the printing paste can be transfected onto the protective glaze through the rubber roller. The components in the adding range enable the glaze to form a concave-convex structure with obvious height difference, and excessive high-temperature protrusion powder (namely, the content of the slip-resistant glaze powder is low) or excessive slip-resistant glaze powder (namely, the content of the high-temperature protrusion powder is low) is difficult to enable anorthite crystal grains and celsian crystal grains with different grain diameters to form obvious height difference, so that the depth of the concave-convex structure is insufficient, and the slip resistance and slip resistance of the glazed tile are reduced.
And D, firing and forming the primary glazed tile product at high temperature, wherein the firing temperature is 1250 +/-5 ℃, and the firing time is 50-65 minutes. The firing conditions are matched with the components of the high-temperature bump powder and the slip-resistant glaze powder in the printing fancy glaze, the firing temperature is lower than the sintering temperature of the high-temperature bump powder and the slip-resistant glaze powder, and substances with good temperature resistance, such as aluminum oxide and the like, in the high-temperature bump powder and the slip-resistant glaze powder are prevented from being completely leveled and losing uneven structures.
And E, edging and packaging the primary glazed tile product to obtain a finished product.
Further, the addition amounts of the high-temperature bump powder, the anti-slip glaze powder and the printing paste in the printing fancy glaze are respectively as follows in parts by weight: 40-60 parts, 40-60 parts and 60-80 parts. Specifically, the printing fancy glaze also contains a suspending agent, and the suspending agent is used for improving the dispersibility of the powdery high-temperature bump powder and the powdery anti-slip glaze powder, so that the powdery high-temperature bump powder and the powdery anti-slip glaze powder stably exist in a printing fancy glaze system and are prevented from settling. The high-temperature convex powder, the anti-slip glaze powder and the printing paste in the proportion are uniformly stirred and then printed and dyed on the protective glaze through roller printing, a special HRT pit digging carving process is applied to the rubber roller, the lower extending depth of the surface carving of the rubber roller reaches 1.20-1.55 mm, the printing fancy glaze is burnt at high temperature, the thickness of a pattern layer on the surface of the ceramic tile reaches 0.95-1.35 mm, and the more obvious concave-convex effect of high-low level fall on the surface of the ceramic tile is ensured, so that the anti-slip and anti-slip effects of the ceramic tile are further improved.
Further, the patterns on the pattern layer in the step C are designed in advance by means of photoshopcs6 drawing software, and the patterns are formed by combining and arranging at least six patterns with different shapes, specifically, the patterns include, but are not limited to, circles, triangles, hexagons, diamonds, arcs and the like. By applying the pattern layer formed by combining patterns in various shapes, the difference of different concave-convex heights on the surface of the ceramic tile can be realized, so that the surface of the ceramic tile achieves effective anti-sliding and anti-skid effects, and the patterns with different shapes can realize multi-surface, infinite and random printing distribution. The line diameter of the pattern is in the range of PX 6-PX 16. The line diameter in the range enables the surface of the ceramic tile to form concave-convex structures with different heights, and when the line diameter is smaller than PX6, the height of the formed concave-convex structures is not obvious, so that the improvement of the anti-skid and anti-slip formation of the surface of the ceramic tile is not facilitated; when the wire diameter is larger than PX16, the roughness of the surface of the ceramic tile is easily increased, and the fineness of the glaze surface is reduced.

Firstly, adding 43% of quartz, 20% of feldspar and 8% of hard clay into 22% of plastic clay according to mass percentage, uniformly stirring, adding 7% of nepheline powder, uniformly mixing, then carrying out ball milling to remove iron, and enabling the fineness to reach 250-mesh sieve residue: 2.0 percent, the density of the slurry reaches 1.70 to 1.75g/cm3. Then, powder with the water content of 5-7% is formed by the procedures of spray drying and the like, and is molded into a green body by a press with the pressure of 550bar, and the green body is dried for 15 minutes at the temperature of 170 ℃ to obtain the green body for later use.
60 parts of high-temperature bump powder, 40 parts of slip-resistant glaze powder, 80 parts of printing paste and the like are used as raw materials, the raw materials are mixed and ground by a high-speed grinder, and the fineness reaches 325 meshes and is less than 0.1 percent after homogenization to prepare the printing fancy glaze for later use. The printing fancy glaze comprises the following components in percentage by mass: SiO 22：41.62％、Al2O3：26.51％、Fe2O3：0.09％、TiO2：0.03％、CaO：4.56％、MgO：1.79％、K2O：3.53％、Na2O: 1.49%, ZnO: 3.74%, BaO: 11.60%, SrO: 1.06%, loss on ignition: 3.98% (1000 ℃), the flow rate of the printing fancy glaze is 20S, and the specific gravity is 1.61.
Then spraying 12-16 g of water by using 800 x 800mm green bodies, and spraying 500 g/m of overglaze on a bell jar2Printing patterns and colors by an ink-jet printer, and then applying 230 g/m of protective glaze by a water jet glaze spraying cabinet2Printing and dyeing the spare printing fancy glaze on the protective glaze by using a roller printing machine, and then carrying out high-temperature glaze firing at 1250 ℃ for 65 min.

The wet-water static friction coefficient of the glazed tile with the anti-slip and anti-slip effects obtained in example 3 is 0.70, which is an extremely safe anti-slip grade. The abrasion resistance of the glaze surface is 1500 turns, 3 grades, and the pollution resistance is 5 grades. (the performance tests are respectively measured by methods of GB/T4100, GB/T3810.7, GB/T3810.14 and the like.)
Comparative example 1
The preparation method of comparative example 1 is basically the same as that of example 1, except that the parts by weight of the printing fancy glaze are different, specifically: the printing fancy glaze is prepared by using 30 parts of high-temperature bump powder, 70 parts of slip-resistant glaze powder, 60 parts of printing paste and other raw materials, mixing and grinding the raw materials through a high-speed grinder, and homogenizing until the fineness reaches 325 meshes and the residual is less than 0.1 percent. The printing fancy glaze comprises the following components in percentage by mass: SiO 22：36.38％、Al2O3：32.54％、Fe2O3：0.07％、TiO2：0.02％、CaO：2.38％、MgO：1.69％、K2O：3.71％、Na2O: 1.28%, ZnO: 3.30%, BaO: 13.82%, SrO: 0.53%, loss on ignition: 4.28% (1000 ℃), the flow rate of the printing fancy glaze is 38S, and the specific gravity is 1.76.
Because the printing fancy glaze obtained by adopting 30 parts of high-temperature bump powder and 70 parts of anti-slip glaze powder in the comparative example 1 has the CaO content of only 2.38 percent by weight, after the printing fancy glaze is fired at high temperature, the number of internal anorthite crystals is reduced, the particle height difference value of the anorthite crystals and the celsian crystals is reduced, and the wet-water static friction coefficient of the finished glazed tile is measured to be 0.59, which is a medium-safety anti-slip grade; the abrasion resistance of the glaze is 1500 turns, 3 grades; in addition, the SrO content in the printing fancy glaze is 0.53 percent by weight, the firing temperature of the printing fancy glaze is slightly higher, the meltability of the glaze surface is slightly poor, the glaze surface has slight open pores, and the pollution resistance is measured to be 4 grades. (the performance tests are respectively measured by methods of GB/T4100, GB/T3810.7, GB/T3810.14 and the like.)
Comparative example 2
Comparative example 2 was prepared in substantially the same manner as in example 1, except thatThe weight parts of the printing fancy glaze are different, and the printing fancy glaze specifically comprises the following components: 70 parts of high-temperature bump powder, 30 parts of slip-resistant glaze powder, 60 parts of printing paste and the like are used as raw materials, the raw materials are mixed and ground by a high-speed grinder, and the fineness reaches 325 meshes and is less than 0.1 percent after homogenization to prepare the printing fancy glaze for later use. The printing fancy glaze comprises the following components in percentage by mass: SiO 22：43.36％、Al2O3：24.50％、Fe2O3：0.01％、TiO2：0.03％、CaO：5.28％、MgO：1.83％、K2O：3.47％、Na2O: 1.56%, ZnO: 3.89%, BaO: 10.86%, SrO: 1.23%, loss on ignition: 3.98% (1000 ℃), the flow rate of the printing fancy glaze is 37S, and the specific gravity is 1.75.
Because the printing fancy glaze obtained by 70 parts of high-temperature bump powder and 30 parts of anti-slip glaze powder is adopted in the comparative example 2, the CaO content in the printing fancy glaze is 5.28 percent by weight, the internal anorthite crystals are more after the printing glaze is fired at high temperature, on the contrary, the BaO content in the printing fancy glaze is 10.86 percent by weight, the relative content is less, and the barium feldspar crystal phase generated at high temperature is insufficient, so that the particle height drop value of the anorthite crystals and the barium feldspar crystals is smaller, and the wet-water static friction coefficient of the finished glazed tile is measured to be 0.55 and is in a medium safe anti-slip grade; in addition, the SrO content in the printing fancy glaze is 1.23 percent by weight, the firing temperature of the printing fancy glaze is obviously reduced, the glaze surface is fully melted, the glass phase is increased, the glossiness of the glaze surface is increased, and the abrasion resistance of the glaze surface is 750 turns and 3 grades; the stain resistance was measured to be grade 5. (the performance tests are respectively measured by methods of GB/T4100, GB/T3810.7, GB/T3810.14 and the like.)
In the comparative examples 1 and 2, the addition amounts of the high-temperature bump powder and the anti-slip glaze powder in the printed fancy glaze cannot achieve the optimal matching proportion, so that the final glazed tile finished product does not achieve the optimal effect in the aspects of performance indexes such as static friction coefficient, wear resistance, pollution resistance and the like.
Comparative example 3
The preparation method of the comparative example 3 is basically the same as that of the example 1, except that the depth under the lines on the rubber roller is 0.5-0.7 mm, and the thickness of the pattern layer is 0.25-0.45 mm.
The lower extension depth of the rubber roller of the comparative example 3 becomes shallow, the thickness of the pattern layer becomes thin after the printing fancy glaze is printed by the roller, the particle height drop value of anorthite crystal and celsian crystal in the glaze layer is reduced after the printing fancy glaze is fired, and the glazed tile prepared by the comparative example 3 is tested to obtain that the wet-water static friction coefficient of the finished glazed tile is 0.50, which is a medium-safety antiskid grade; measuring the wear resistance of the glaze surface to be 1500 turns and 3 grades; the stain resistance was measured to be grade 5. (the performance tests are respectively measured by methods of GB/T4100, GB/T3810.7, GB/T3810.14 and the like.)
Comparative example 4
The preparation method of the comparative example 4 is basically the same as that of the example 1, except that the depth under the lines on the rubber roller is 1.85-2.00 mm, and the thickness of the pattern layer is 1.55-1.95 mm.
The lower extension depth of the rubber roller of the comparative example 4 is increased, so that after the printing fancy glaze is printed by the roller, the thickness of the fancy layer is increased, but the roller printing is not facilitated, and the cleaning difficulty of the rubber roller is increased; and the fired glaze has rough hand feeling and reduced fineness, which is not beneficial to the color generation of the pattern texture layer.
In summary, on one hand, the printing fancy glaze containing high-temperature protrusion powder and anti-slip glaze powder is printed on the surface of the ceramic tile, the high-temperature protrusion powder adopts low silicon, medium aluminum, high barium and high calcium, so that a large amount of anorthite and celsian crystal glaze layers are generated after firing, the anti-slip glaze powder adopts low silicon, high aluminum and high barium, so that a large amount of celsian glaze layers are generated after firing, the two glaze layers are matched to form a mixed glaze layer which is fine, smooth, not rough, low in glossiness, high in transparency, less in glass phase and rich in crystal phase, and two crystal phases contained in the glaze layer can effectively form surface height difference due to particle size difference to generate a concave-convex surface layer, so that the glaze layer has anti-slip and anti-slip effects; on the other hand, a special HRT pit digging rubber roll engraving process is adopted, the lower extension depth of engraving on the surface of the rubber roll reaches 1.20-1.55 mm, after the printing fancy glaze is fired at high temperature, the surface pattern layer can reach the thickness of 0.95-1.35 mm, the height difference between the pattern layer and the surface of the protective glaze layer can be effectively generated, and an obvious concave-convex effect is formed, so that the anti-sliding and anti-sliding effects of the glazed tile are further improved; through various different patterns designed in advance, the pattern layer has the effects of skid resistance, skid resistance and attractive appearance; the surface of the glazed tile with the anti-skid and anti-skid effects forms a concave-convex structure with large height difference, so that the glazed tile has good anti-skid and anti-skid properties, and the wet-water static friction coefficient of the glazed tile reaches over 0.7; the glaze layer has high transparency, the glazed tile has bright color, the pattern texture of the glazed tile is clear, and the glaze is fine, smooth and soft and has good hand feeling; the glaze is wear-resistant, the antifouling reaches five grades, and the glaze is sanitary, clean, convenient and easy; and the surface of the glazed tile presents various patterns with different shapes, so that the glazed tile is more attractive, natural and abundant.
