[0003] In the past two or three years, the velvet ceramics derived from the ceramic tile industry are required to have multiple characteristics such as softness, texture, and delicacy. Ceramic tile manufacturers have also strengthened research and development in this regard. At the same time, they hope to develop velvet ceramics with the above-mentioned characteristics and more other characteristics to suit a wider range of people. Summary of the invention

[0012] Preferably, the thickness of the glaze layer is 7-10 mm.

[0013] Preferably, the polishing thickness of step (2) is 1 / 7 to 1 / 6 of the glaze thickness of the semi-finished ceramic tile.

[0014] Preferably, the particles described in step (4) are nanoparticles.

[0015] Preferably, the diameter of the nanoparticles is 50-300 nm.

[0016] Preferably, the weight ratio of nanoparticles: etching solution = 1:10-20.

[0025] The invention discloses a velvet anti-skid tile and a process thereof, which has a soft appearance, a strong texture, and high delicacy, and also has an anti-skid effect, thereby achieving the coexistence of multiple characteristics.

[0026] A production process of velvet anti-slip tiles of the present invention comprises the following steps:

[0027] (1) Take the formed brick, sprinkle water, apply the base glaze, spray the fine carving ink, dry at low temperature to fix the shape, apply the top glaze, and fire at high temperature to obtain the semi-finished ceramic tile;

[0028] (2) polishing the finished ceramic tile to obtain a ceramic tile body;

[0029] (3) Waxing the brick surface;

[0030] (4) Applying an etching solution containing particles, and maintaining the etching time for 5-15 seconds;

[0031] (5) Dry and clean the brick surface;

[0032] (6) Apply anti-skid wax, dry and solidify the anti-skid wax layer to make velvet anti-skid tiles.

[0033] Preferably, the thickness of the glaze layer is 7-10 mm.

[0034] More preferably, the thickness of the glaze layer is 7-8 mm or 9-10 mm.

[0035] Preferably, the polishing thickness of step (2) is 1 / 7 to 1 / 6 of the glaze thickness of the semi-finished ceramic tile.

[0036] Preferably, the particles described in step (4) are nanoparticles.

[0037] Preferably, the diameter of the nanoparticles is 50-300 nm.

[0038] Preferably, the weight ratio of nanoparticles: etching solution = 1:10-20.

[0039] Preferably, the coating in step (4) is performed at a speed of 10-30 m / s for 2-4 seconds, and then the etching solution is retained for 3-11 seconds.

[0040] Preferably, the waxing thickness in step (3) is 0.3-1.5 mm higher than the surface glaze layer.

[0041] Preferably, the water spray is mist water with a particle size of 50-80 μm.

[0042] Preferably, the anti-slip wax is in a wax water state.

[0043] Preferably, after applying the glaze, the brick is gently shaken.

[0044] The present invention also provides a velvet anti-skid tile, which is made by the production process of the velvet anti-skid tile described above.

[0045] The present invention takes a different approach and uses a method different from the prior art to achieve the coexistence of multiple effects.

[0046] After the brick blank of the present invention is pressed into shape, it is sprinkled with water, and the mist water with a particle size of 50-80μm is sprinkled to provide a flat surface for the base glaze. Then, the fine carving ink is sprayed, and the low-temperature drying at 500-600℃ is performed for shaping. Then, the surface glaze is applied. At this time, the brick blank can be gently shaken to make the surface glaze fit the surface of the brick blank, and then high-temperature firing is performed to make the semi-finished ceramic tile of the present invention.

[0047] Therefore, the pattern texture of the present invention is made in a very flat state, so the present invention has a strong visual sense, a strong touch, and a high degree of delicacy, just as delicate as velvet.

[0048] Then, the surface of the brick body is ground and polished, and the polishing depth is 1 / 7 to 1 / 6 of the thickness of the removed glaze layer, so as to effectively expose more of the pores of the brick body.

[0049] Next, apply wax to the surface of the glaze layer of the brick body and allow it to penetrate into the pores. A wax is preferred, but homopolymer wax can also be used. This solves the problem of dirt hiding in the pores on the surface of the brick body, achieves the initial anti-fouling performance of the entire tile, and at the same time maintains a relatively thin thickness so that the etching liquid in the subsequent process can form a good coating structure.

[0050] Next, an etching solution mixed with nanoparticles is coated on the surface of the brick, the diameter of the nanoparticles is 50-350nm, preferably 50-300nm, more preferably 50-150nm, the weight ratio of nanoparticles: etching solution is 1:10-20, and first impact at a rate of 10-30 m / s for 2-4 seconds, that is, spray for 2-4 seconds, spraying refers to the comprehensive spraying of the entire brick surface, and then the etching solution is retained on the surface of the brick for 3-11 seconds, so that a large number of microscopic etching pits appear on the surface of the brick, thereby enhancing the roughness of the brick surface and the anti-slip performance. At the same time, it also provides a guarantee for the subsequent anti-slip wax processing, which is beneficial to the stability of the anti-slip wax, thereby improving the overall durability of the tile.

[0051] Then, preferably, a rubber scraper is used to remove the liquid on the surface of the brick body, and then a grinding head is used to almost completely clean the etching liquid and particles to prepare for the next process.

[0052] Finally, use water-based anti-skid wax to drip onto the surface of the brick, use a grinding head to evenly spread the wax water and allow it to penetrate and fully fill the etched pits. It is best to repeat the operation multiple times, and finally dry and solidify it to form an anti-skid wax layer to achieve an anti-skid effect, and can also play an anti-fouling and anti-transparency role.

[0053] The ceramic tile of the present invention has fine pores on the ceramic tile body coated with wax after the polishing process, so that there are fewer places for dirt to hide between the fine pores and the wax. However, due to the different materials, finer water vapor can still penetrate. When there are fine pores in the ceramic tile and water vapor is hidden, it acts like the adsorption of a small suction cup, achieving the first layer of anti-slip effect.

[0054] When the etching liquid is applied to the brick by spraying and impacting, the nanoparticles hit the surface of the brick due to the impact effect, forming uniform pits. In addition, the etching liquid "corrodes" the surface of the brick, forming countless nano-sized pores. After cleaning, apply water-based anti-slip wax. After the anti-slip wax is fully filled in the pits and the surface of the brick, it is dried and solidified to form an anti-slip wax layer, achieving a second layer of anti-slip effect.

[0055] Moreover, this anti-slip wax layer is like growing little feet, and the part that "sinks" into the holes is firmly fixed on the brick body like little feet, and is very stable; further, even if the anti-slip wax layer is worn out under long-term and strong friction, the product structure formed by the glaze layer of the brick body and the etched pits on the microstructure is difficult to wear out, so it has a longer lifespan than conventional anti-slip tiles.

[0056] The ceramic tile made by the present invention has both velvety fineness and anti-slip effect, and also maintains good anti-fouling performance and high transparency, thus solving the common problems of fineness and anti-slip, and is a technological breakthrough.
