Description
Technical Field
The application relates to the technical field of building ceramics, in particular to an ultrathin ceramic tile with concave-convex textures and a preparation method thereof.
Background
In recent two years, with the popularity of large plates and rock plate products and the increase of the application proportion of ceramic products on wall surfaces, table tops and counter surfaces, consumers have raised higher demands on building ceramic products, not only pursuing the individual pattern decoration design and excellent physical and chemical properties of the ceramic products, but also raising higher demands on the surface texture and touch feeling of the ceramic products, and under the background, ceramic tiles with concave-convex texture effects are generated. In addition, the ultrathin bricks have the advantages of less raw material consumption, less energy consumption, space saving and the like, and are favored by ceramic enterprises and consumers, so that the realization of the concave-convex texture effect on the ultrathin bricks is becoming more and more important.
Currently, in order to achieve a stereoscopic 3D relief texture effect on the tile surface, the following preparation process is generally adopted: (1) The water-soluble glaze is discharged on the surface of the green brick by using oily die/engraving/deep effect ink to form a concave-convex texture effect, but the process creates the concave-convex texture effect by using repulsive force between the ink and the glaze, so that when the green brick is thinner, the green brick is cracked or broken; in addition, when a wider line texture is needed, if the performance of the oily ink is improperly matched, glaze beads are easily generated in the grooves, and the definition of the concave-convex texture is affected; (2) The sinking ink and the glaze material are adopted to carry out chemical reaction, so that concave-convex textures are formed on the glaze layer, but the concave line textures formed by the method are formed by melting, volatilizing and corroding low-temperature substances at high temperature, so that the corners of the formed textures are easy to collapse, are not three-dimensionally sharp enough, and influence the effect of the concave-convex textures.
In summary, in the prior art, it is difficult to form fine concave-convex textures on the ultrathin bricks so as to meet the use requirements.
Disclosure of Invention
The application aims at providing a preparation method of an ultrathin ceramic tile with concave-convex textures, which has the advantages of simple steps and strong operability, and can not only realize concave-convex texture effects on green bricks with conventional thickness, but also obtain three-dimensional concave-convex texture effects with clear textures and high fidelity on the surfaces of the ultrathin ceramic tiles by combining a novel texture ink raw material formula with a texture ink printing process, and simultaneously has wear resistance, corrosion resistance and dirt resistance so as to meet the use requirements and overcome the defects in the prior art.
The second purpose of the application is to provide an ultrathin ceramic tile prepared by the preparation method of the ultrathin ceramic tile with concave-convex texture, which has a three-dimensional concave-convex texture effect, and has wear resistance of at least 4 grade 2100 turns, corrosion resistance of at least grade GB (V) and stain resistance of at least grade 5.
To achieve the purpose, the application adopts the following technical scheme:
the preparation method of the ultrathin ceramic tile with the concave-convex texture comprises the following steps:
A. preparing a ceramic blank, pressing the ceramic blank, and drying to obtain a blank layer, wherein the thickness of the blank layer is 1-4 mm;
B. printing texture ink according to a preset pattern to form a concave-convex texture layer; wherein the ink jet quantity of the texture ink is 20-155 g/m 2 According to the mass percentage, the texture ink comprises 24-40% of zirconium silicate, 5-20% of quartz, 0.5-10% of zinc oxide, 1-6% of polymer dispersant and 45-55% of solvent;
C. and (5) drying and firing in a kiln to obtain the ultrathin ceramic tile with concave-convex textures.
Further, according to the mass percentage, the content of ferric oxide in the zirconium silicate is less than or equal to 0.05 percent, and the D50 particle size of the zirconium silicate is 800-1000 nm;
the purity of the quartz is more than or equal to 99.999 percent, and the purity of the zinc oxide is more than or equal to 99.8 percent.
Further, in the step B, the D50 particle size of the texture ink is less than 350nm, and the viscosity is 15-25 mPa.s at 40 ℃.
Further, in the step B, the specific gravity of the texture ink is 1.25-1.40 g/cm 3 The surface tension is 25 to 35mN/m.
Further, in the step B, the solvent is any one or a combination of more than one of isopropyl laurate, fatty acid and isopropyl oleate;
the polymer dispersant is copolyformaldehyde.
Further, step D is included, and step D is located before and/or after step B;
the specific steps of the step D are as follows: printing color ink according to a preset pattern to form a color pattern layer.
Further, the method also comprises a step E, wherein the step E is positioned before the step B, and the specific steps of the step E are as follows: applying a primer on the green body layer to form a primer layer;
wherein the glazing amount of the ground coat is 250-500 g/m 2 。
Further, step F is further included, and step F is located before step C, where the specific steps of step F are as follows: applying surface glaze to form a surface glaze layer.
In the step A, the drying temperature of the drying step is 170-190 ℃ and the drying time is 32-61 min.
The ultrathin ceramic tile with the concave-convex texture is prepared by the preparation method of the ultrathin ceramic tile with the concave-convex texture, the wear resistance of the ultrathin ceramic tile at least reaches grade 4 2100 r, the corrosion resistance at least reaches grade GB (V), and the stain resistance reaches grade 5.
The technical scheme provided by the embodiment of the application can have the following beneficial effects:
1. by optimizing the texture ink formula and utilizing the raw materials with lower high-temperature fluidity in the formula system, the texture ink still keeps the original position after entering a kiln for firing and has the original thickness, so that not only can the concave-convex texture effect be realized on the green brick with the conventional thickness, but also the three-dimensional concave-convex texture effect with clear texture and high fidelity can be obtained on the surface of the ultrathin ceramic tile, and meanwhile, the ceramic tile has the wear resistance, corrosion resistance and pollution resistance so as to meet the use requirement.
2. The texture ink is printed in an ink-jet printing mode to form the concave-convex texture layer, so that full-coverage printing or partial printing of the texture ink on the blank layer can be realized, and the ink consumption is greatly reduced compared with that of the traditional screen printing no matter the full-coverage printing or the partial printing is adopted. It should be noted that the printing mode of the full coverage printing or the partial printing may be implemented by setting a preset pattern of the texture ink in the inkjet printer.
3. In order to be favorable for ensuring the concave-convex texture effect of the fired ceramic tile, the proposal preferably has the ink jet quantity of 20-155 g/m 2 . If the ink jet amount is more than 155g/m 2 The surface with the concave-convex effect will be cracked, which cannot meet the actual requirement.

In order to solve the problems that the surface of an ultrathin ceramic tile cannot obtain a three-dimensional concave-convex texture effect with clear texture and high fidelity and simultaneously has wear resistance, corrosion resistance and stain resistance in the prior art, the technical scheme provides a preparation method of the ultrathin ceramic tile with concave-convex texture, which comprises three steps of A (blank making), B (texture ink printing) and C (kiln firing drying), and the three-dimensional concave-convex texture effect with clear texture and high fidelity can be obtained on the surface of the ultrathin ceramic tile besides the concave-convex texture effect on the ceramic tile with conventional thickness by combining an innovative texture ink formula with a texture ink printing process, so that the use requirements are met. It should be noted that, the green body layer in this embodiment is formed by pressing and drying a ceramic blank that is conventional in the ceramic field, and the ceramic blank is not further described herein.
Specifically, the technical scheme provides texture ink, which comprises zirconium silicate, quartz, zinc oxide, a polymer dispersing agent and a solvent, wherein the raw materials comprise zirconium silicate, quartz, zinc oxide, a polymer dispersing agent and a solvent, the formula of the texture ink is optimized, and the raw materials with lower high-temperature fluidity in a formula system are utilized to ensure that the texture ink still keeps the original position after being fired in a kiln and has the original thickness, so that not only can the concave-convex texture effect be realized on a brick blank with the conventional thickness, but also the three-dimensional concave-convex texture effect with clear texture and high fidelity can be obtained on the surface of an ultrathin ceramic tile, and meanwhile, the texture ink has wear resistance, corrosion resistance and pollution resistance, so as to meet the use requirements.
The raw material with lower high-temperature fluidity commonly adopted in the existing ceramic field is alumina, but the acid and alkali resistance and corrosion resistance of a formula system are poor due to poor acid and alkali resistance of the alumina, so that the ceramic tile is not beneficial to daily use of the ceramic tile. In order to overcome the defects, zirconium silicate, quartz and zinc oxide are added into texture ink raw materials to form a silicon-zirconium-zinc system, and the content of zirconium silicate in the silicon-zirconium-zinc system is highest, so that the texture ink is ensured to have lower high-temperature fluidity, and the ultra-thin ceramic tile surface is enabled to obtain a three-dimensional concave-convex texture effect with clear texture and high fidelity. However, as the melting point of zirconium silicate is higher, if zirconium silicate is only added into a silicon-zirconium-zinc system, texture ink is burnt to deteriorate the effect of concave-convex textures, so that quartz is added into the silicon-zirconium-zinc system, the quartz has poorer high-temperature fluidity than zirconium silicate although the high-temperature fluidity is improved, and the melting point of the quartz is lower than that of zirconium silicate, and the zirconium silicate is matched with the quartz to ensure that the texture ink still has lower high-temperature fluidity, the texture ink cannot be burnt, and the three-dimensional concave-convex texture effect with clear textures and high fidelity is ensured to be obtained on the surface of an ultrathin ceramic tile. In addition, the silicon-zirconium-zinc system has acid-base resistance and corrosion resistance, so that the texture ink layer can be endowed with better acid-base resistance and corrosion resistance.
Besides, as the content of zirconium silicate in the silicon-zirconium-zinc system is higher, the shrinkage rate and porosity of the concave-convex texture layer are larger, so that micropores are easy to appear in the concave-convex texture, and the concave-convex texture effect and the stain resistance are poor. If the zinc oxide content is low, the texture ink water is burnt, so that the concave-convex texture effect is poor, and meanwhile, the flatness of the ceramic tile is affected by the texture ink water burning, so that the pollution resistance is reduced, and the daily use is not facilitated; if the zinc oxide content is too high, the fluidity of the texture ink is too high, so that the texture ink cannot be well fixed, the definition of the concave-convex texture is poor, and the effect of the concave-convex texture is also affected.
In addition, the texture ink raw material of the technical scheme also comprises a polymer dispersing agent and a solvent, wherein the dispersing agent can improve the viscosity of the solution, so that the texture ink has certain fixing performance, and the problem that the concave-convex texture cannot be fixed and a concave-convex texture layer cannot be formed due to the fact that the texture ink is diffused immediately after being applied is avoided; meanwhile, the polymer dispersant is matched with the solvent, so that the texture ink is ensured to have proper viscosity, the stability of the solution is improved, and performance degradation caused by agglomeration and precipitation is avoided.
More specifically, prior art cloth implementations of textured inks generally include both screen printing and inkjet printing. When screen printing is performed by using texture ink, the required texture ink is large in usage amount, and raw material waste is easy to cause; in addition, because the silk screen pattern is fixed pattern, can not carry out nimble change to the texture ink pattern of inkjet printing, when the production line of ceramic tile need trade when producing, for example when producing the ceramic tile of different patterns, need to readjust or change silk screen pattern, lead to the production line to trade to produce difficultly, greatly reduced the production efficiency of ceramic tile, and improved the manufacturing cost of ceramic tile. Therefore, the technical scheme adopts an ink-jet printing mode to print texture ink to form the concave-convex texture layer, so that full-coverage printing or partial printing of the texture ink on the blank layer can be realized, and the ink consumption is greatly reduced compared with that of the traditional screen printing no matter the full-coverage printing or the partial printing is realized. It should be noted that the printing mode of the full coverage printing or the partial printing may be implemented by setting a preset pattern of the texture ink in the inkjet printer.
Meanwhile, in order to be beneficial to ensuring the concave-convex texture effect of the baked ceramic tile, the ink jet quantity is preferably 20-155 g/m 2 . If the ink jet amount is more than 155g/m 2 The surface with the concave-convex effect will be cracked, which cannot meet the actual requirement.
Preferably, in the step C, the drying temperature in the drying step is 140-160 ℃ and the drying time is 30-50 s; the sintering temperature in the sintering step is 1160-1230 ℃, and the sintering time is 51-120 min.
More preferably, in the step C, the drying temperature in the drying step is 150 ℃ and the drying time is 40s.
Further, according to the mass percentage, the content of ferric oxide in the zirconium silicate is less than or equal to 0.05%, and the D50 particle size of the zirconium silicate is 800-1000 nm;
the purity of the quartz is more than or equal to 99.999 percent, and the purity of the zinc oxide is more than or equal to 99.8 percent.
Since the properties of textured inks are greatly affected by the particle size and purity of zirconium silicate, quartz and zinc oxide, the properties of textured inks will be affected when conventional zirconium silicate, quartz and zinc oxide are used. Therefore, the method further ensures the performance of the texture ink by controlling the content of ferric oxide in the zirconium silicate, the purities of quartz and zinc oxide and the grain size of the zirconium silicate. The content of ferric oxide in zirconium silicate is less than or equal to 0.05%, and if the content of ferric oxide in zirconium silicate is higher, the brick surface is yellow, and the brick surface effect is affected. Further, when zirconium silicate is used as a ceramic glaze additive, the wear resistance and corrosion resistance are improved along with the reduction of the particle size within a certain particle size range, and the consumption is reduced, so that the D50 particle size of the zirconium silicate is limited to 800-1000 nm, the three-dimensional concave-convex texture effect is ensured, the wear resistance and corrosion resistance of the obtained ceramic tile can be improved, and the consumption is reduced; if the grain size of the zirconium silicate is too small, the effect of concave-convex texture can be affected; if the grain size of the zirconium silicate is too large, the wear resistance and corrosion resistance of the zirconium silicate are reduced, and the performance of the ceramic tile is affected.
Furthermore, the purity of quartz is more than or equal to 99.999 percent, and the purity of zinc oxide is more than or equal to 99.8 percent, because the texture ink directly forms concave-convex effect in the scheme, the concealing function of a glaze layer is not needed, if the purities of quartz and zinc oxide are lower, the tiny defects on the glaze surface can be presented, the tile surface effect of the ceramic tile and the performance of the obtained ceramic tile are easily influenced, therefore, the purities of the quartz and the zinc oxide in the technical scheme are limited, and the performance of the ceramic tile is ensured.
Further, in the step B, the grain size of the texture ink is D50 < 350nm, and the viscosity is 15-25 mPa.s at 40 ℃.

It should be noted that, the color pattern layer in this embodiment is printed by color ink that is conventional in the ceramic field, and the color ink is not further described herein.

The procedure is the same as in example 1 except that the texture ink is used differently from example 1, namely, the texture ink of comparative example 1 is replaced with a prior art engraving ink, and the engraving ink comprises a lipid solvent C in mass percent 15 H 30 O 2 6% of fatty methyl formate C 93 H 174 O 10 13% of ceramic mixture SiO2 20% of lipid solvent C 22 H 42 O 6 40% hydrotreated middle distillate C 14 H 30 3% of a polymeric dispersant C 6 H 10 O 4 2% and aluminosilicate AlO 8 16% of Si, na and the rest are the same as in example 1.
Comparative example 2
Alumina was used instead of zirconium silicate and quartz in the texture ink formulation of example 1, the remainder being the same as example 1, i.e., comparative example 2, the texture ink comprising, in mass percent, 44% alumina, 2.1% zinc oxide, 3.7% copolyoxymethylene and 50.2% stearic acid, the remainder being the same as example 1.
Comparative example 3
The procedure was the same as in example 1 except that the ink jet amount of the texture ink was different from that of example 1, in which the ink jet amount of the texture ink in comparative example 3 was 160g/m 2 。
Comparative example 4
The procedure of example 1 was repeated except that the texture ink was prepared in the same manner as in example 1 except that the texture ink was composed of, by mass, 28.4% of zirconium silicate, 17.2% of quartz, 4.2% of copolyformaldehyde and 50.2% of stearic acid.
Comparative example 5
The procedure of example 1 was repeated except that the texture ink was prepared in the same manner as in example 1 except that the texture ink was composed of, by mass, 27.2% of zirconium silicate, 9.5% of quartz, 10.2% of zinc oxide, 4.9% of copolyformaldehyde and 48.2% of stearic acid.
Comparative example 6
The procedure of example 1 was repeated except that the content of iron oxide in zirconium silicate, the D50 particle size of zirconium silicate, the purity of quartz and the purity of zinc oxide were different from those of example 1. Wherein, the content of ferric oxide in the zirconium silicate is 0.06%, the D50 particle size of the zirconium silicate is 1100nm, the purity of quartz is 99.9%, and the purity of zinc oxide is 99.7%.
The tiles obtained in comparative examples 1 to 6 were subjected to corresponding performance tests, the results of which are shown in table 2 below:
table 2 results of performance tests on different tiles in comparative example
As is clear from table 2, the conventional engraving ink was used in comparative example 1, and thus the uneven texture could not be formed on the tile surface.
Because the alumina is used for replacing zirconium silicate and quartz in the texture ink formula in the comparative example 2, the wear resistance and corrosion resistance of the formula system are poor, and the daily use of the ceramic tile is not facilitated.
Since the ink jet amount of the texture ink in comparative example 3 was 160g/m 2 The surface of the formed concave-convex effect generates cracks, the surface effect of the ceramic tile is affected, and the actual requirements cannot be met.
The tile of comparative example 4 and comparative example 5 has poor concave-convex texture effect because the comparative example 4 does not contain zinc oxide, which causes burning of texture ink water, so that the concave-convex texture effect is poor, and at the same time, the burning of texture ink water also affects the flatness of the tile, thereby causing degradation of stain resistance, which is unfavorable for daily use; in comparative example 5, however, the zinc oxide content was too high, which resulted in too high fluidity of the textured ink, which resulted in poor fixation of the textured ink, and poor definition of the uneven texture, which affected the effect of the uneven texture, and the sum of the added amounts of zirconium silicate and quartz in the formulation system was reduced, resulting in a decrease in acid-base resistance and abrasion resistance.
The tile of comparative example 6 was yellowish in surface, which is caused by the high content of iron oxide in zirconium silicate, and at the same time, the abrasion resistance and corrosion resistance of the tile were reduced as compared with example 1 due to the excessively large particle size of zirconium silicate and the low purity of quartz and zinc oxide.
