Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of ceramics, and in particular relates to a stone-like glazed ceramic tile and a preparation method thereof. BACKGROUND

[0002] China is the world's largest producer of buildings and ceramics, and also has the world's largest ceramic consumption market, but the overall economic benefits of the ceramic market in China are not high. The main difference between high-end products abroad and China is the processing of glaze and color patterns. The selection of glaze has a very crucial influence on the glaze effect and color pattern processing of ceramics.

[0003] At present, with the continuous development of the ceramic field, people's demand for ceramic tiles is not only limited to meeting the basic hardness, wear resistance and other properties, but also often requires ceramic tiles to have the visual effect of simulated stone, so as to improve the decorative performance of ceramic tiles and broaden the application scenarios of ceramic tiles. However, although the glaze layer formed by the stone-like glaze used in the prior art can make the ceramic tile obtain a visual effect close to stone, it will also cause the ceramic tile to have a too high surface gloss and a too smooth touch, and has a negative impact on the wear resistance and color development effect of the ceramic tile.

[0004] Therefore, it is urgent to research a ceramic tile with a matte material, a delicate touch, high wear resistance and good color development effect. SUMMARY

[0005] In order to solve the problems of too high gloss, poor wear resistance, rough touch and poor color development effect of stone-like glazed ceramic tiles, the present application provides a stone-like glazed ceramic tile and a preparation method thereof.

[0006] In a first aspect, the present application provides a stone-like glazed ceramic tile, which adopts the following technical scheme:

[0007] A stone-like glazed ceramic tile, which comprises, from bottom to top, a body, a bottom glaze layer, a pattern layer, a printing layer and a stone-like glaze layer;

[0008] The stone-like glaze layer comprises stone-like glaze, and the stone-like glaze comprises, in terms of weight parts, 91.2-96.2 parts of a first frit, 0.2 parts of CH9 sodium carboxymethyl cellulose, 0.5 parts of sodium tripolyphosphate, 1-1.3 parts of a second frit and 1.2-1.6 parts of a third frit.

[0009] The first frit comprises, in terms of weight parts, SiO2 45-50 parts, Al2O3 20-25 parts, K2O 2-3 parts, Na2O 3-4 parts, MgO 0.5-1 part, CaO 3-6 parts, Li2O 0.5-1 part, SrO 5-6 parts, ZnO 10-14 parts and ZrSiO4 1-3 parts, based on the weight parts of the first frit.

[0010] The second frit comprises, by weight fraction, SiO245-50 parts, Al2O320-25 parts, Fe2O36-10 parts, CaO 4-6 parts, K2O 3-4 parts, Na2O 1-2 parts, MgO 2-3 parts, based on the weight fraction of the second frit.

[0011] The third frit comprises, by weight fraction, CaO 26-31 parts, MgO 18-22 parts, CO2 40-44 parts, SiO2 0.5-1 parts, Al2O3 0.5-1 parts, Fe2O3 0.5-1 parts, based on the weight fraction of the third frit.

[0012] There are many ceramic glaze recipes, and different ingredients and proportions will result in differences in firing process, product performance, etc. Through the cooperation of the first frit, the second frit and the third frit, supplemented by zirconium silicate and zinc oxide, the comprehensive performance of the stone glaze ceramic tile can be significantly improved, and the batching is convenient and easy to produce.

[0013] Specifically, in the stone glaze ceramic tile of the present application, first, through the cooperation of zirconium silicate and the second frit, the melt viscosity can be increased, and the crystal growth rate can be controlled, avoiding the phenomenon of glaze layer devitrification due to the excessive growth of crystals in the system, improving the wear resistance of the stone glaze ceramic tile and making it obtain a delicate touch. At the same time, through the cooperation of the second frit and the third frit, the second frit and the third frit can react with alumina and zirconium silicate to generate zirconium silicate mullite crystals during the firing process, which can further improve the hardness of the glaze layer and thus improve the wear resistance of the glaze layer, and on the other hand, zirconium silicate mullite crystals are also beneficial to improve the light transmittance and color rendering effect of the glaze layer. Second, zirconium silicate can be distributed around silicon oxide and aluminum oxide to play the role of matrix skeleton, thereby improving the glaze strength, avoiding the uneven glaze surface due to phase change and deformation of the system during the firing process, and further improving the stability and delicate touch of the stone glaze layer. The cooperation of zinc oxide and zirconium silicate can effectively reduce the high temperature viscosity of the system, reduce the expansion coefficient of the stone glaze during the firing process, improve the firing effect and the texture of the stone glaze layer, and further significantly improve the color rendering effect of the stone glaze while expanding the melting range of the stone glaze. Finally, a stone glaze ceramic tile with excellent wear resistance and delicate touch, matte effect and color rendering effect is obtained.

[0014] As a further improvement of the above technical solution, the mass ratio of ZrSiO4 to ZnO in the first frit is 1:(3.5-4).

[0015] By controlling the mass ratio of ZrSiO4 and ZnO, the wear resistance of the stone glazed ceramic tile can be improved, and the stone glazed ceramic tile can obtain a matte effect, so that the surface gloss of the stone glazed ceramic tile is neither too high nor too low, and the surface of the ceramic tile has a delicate touch.

[0016] As a further improvement of the above technical solution, the mass ratio of ZrSiO4 to the total mass of K2O, Na2O, MgO and CaO in the first frit is 1:(4-4.5).

[0017] By controlling the mass ratio of ZrSiO4 to the total mass of K2O, Na2O, MgO and CaO, the expansion coefficient of the stone glaze is reduced, the thermal stability is improved, and the stone glazed ceramic tile can have excellent wear resistance while having a delicate touch.

[0018] As a further improvement of the above technical solution, the first frit further comprises, by weight: TiO2 0.01-0.04 parts, Fe2O3 0.05-0.1 parts, BaO 0.01-0.06 parts, Cs2O 0.1-0.15 parts, P2O5 0.2-0.5 parts, F 0.9-1 part, Rb2O 0.1-0.2 parts, and anti-skid agent 0.04-0.14 parts.

[0019] As a further improvement of the above technical solution, the stone glaze further comprises, by weight: preservative 0.2 parts and water 33 parts.

[0020] As a further improvement of the above technical solution, the base glaze layer comprises a base glaze, and the base glaze comprises, by weight: FGKT frit 98.5 parts, calcined alumina 1.3 parts, CH9 sodium carboxymethyl cellulose 0.1 parts, sodium tripolyphosphate 0.3 parts, preservative 0.1 parts, and water 32-35 parts.

[0021] As a further improvement of the above technical solution, based on the weight fraction of the FGKT frit, the FGKT frit comprises, by weight: SiO2 45-51 parts, Al2O3 22-24 parts, K2O 3-4 parts, Na2O 4-6 parts, CaO 4-7 parts, Li2O 0.5-1 parts, SrO 5-6 parts, and ZnO 7-9 parts.

[0022] When the FGKT frit does not contain magnesium oxide components, the free oxygen released by magnesium oxide in the base glaze during high-temperature calcination can be avoided, the network structure is not damaged, and the color development effect of the glaze is not affected; at this time, the melt viscosity is reduced, so that the base glaze can be fully combined with the body, and the bonding tightness between the glaze layers is significantly improved.

[0023] As a further improvement of the above technical solution, the FGKT frit comprises, in weight parts, TiO2 0.01-0.03 parts, Fe2O3 0.07-0.12 parts, BaO 0.02-0.05 parts, Cs2O 0.1-0.13 parts, P2O5 0.3-0.6 parts, F 0.92-0.97 parts, Rb2O 0.1-0.16 parts, and anti-skid agent 0.08-0.13 parts.

[0024] In a second aspect, the present application further provides a preparation method of the stone glaze ceramic tile, which adopts the following technical solution.

[0025] A preparation method of the stone glaze ceramic tile, comprising the following steps:

[0026] Step one, after the body is pressed and formed, drying is performed, and the base glaze is applied to the body to form the base glaze layer;

[0027] Step two, color paste is applied to the surface of the base glaze layer to form the pattern layer;

[0028] Step three, color ink is applied to the surface of the pattern layer to form the printing layer;

[0029] Step four, the stone glaze material is applied to the surface of the printing layer to form a glaze-applied body, and the glaze-applied body is fired to obtain the stone glaze ceramic tile.

[0030] As a further improvement of the above technical solution, the color ink is applied to the pattern layer by intelligent inkjet printing.

[0031] As a further improvement of the above technical solution, the stone glaze is applied to the printing layer by bell jar spraying.

[0032] Due to the specific patterns and patterns on the surface of the ceramic tile, the setting of the base glaze layer can avoid the bleeding and color deviation of the ink during the inkjet printing process, and the selection of the stone glaze material can increase the wear resistance of the ceramic, avoid the wear of the pattern layer and the printing layer or / and the reaction of the external environment, and will not affect the color development of the ink, significantly improve the light transmittance and color development effect of the stone glaze ceramic tile.

[0033] As a further improvement of the above technical solution, the specific gravity of the base glaze is 1.86g / cm 3 -1.92g / cm 3 , the flow rate is 30-40s, and the glaze application amount is 400g / m 2 -800g / m 2 .

[0034] By controlling the application parameters of the base glaze, the adhesion of the base glaze to the body is improved, and a base glaze layer with uniform thickness is generated on the surface of the body, so that the subsequent color paste and color ink will not cause bleeding after application, and the color development effect of the stone glaze ceramic tile is improved.

[0035] As a further improvement of the above technical solution, the specific gravity of the stone glaze is 1.85g / cm 3 -1.90g / cm 3 , the flow rate is 37-42s, and the glaze application amount is 410g / m 2 -440g / m 2 .

[0036] By controlling the application parameters of the stone glaze, the stone glaze can be closely combined with the printing layer, avoiding cracks and other conditions during firing, improving the visual effect of the stone glaze ceramic tile, and making the ceramic tile surface feel delicate and wear-resistant.

[0037] As a further improvement of the above technical solution, the firing temperature in step four is: first, increase the temperature to 1000℃ at a temperature increasing rate of 45-55℃ / min, and keep it for 20min; then increase the temperature to the highest firing temperature at a temperature increasing rate of 3-8℃ / min, and keep it for 15min, and finally cool down in the kiln; the highest firing temperature is 1150□1190℃.

[0038] By using the stone glaze material of the present application in combination with a specific construction process, a stone glaze ceramic tile with strong interlayer bonding force, high glaze surface strength, stone visual effect, matte, wear resistance and good color development effect can be obtained.

[0119] From Examples 1-3, Comparative Examples 1-3, Table 1 and Figure 1 、 4 -6, it can be seen that by adding zirconium silicate, zinc oxide, the second frit and the third frit into the jade glaze, a significant synergistic effect between the components in the jade glaze can be achieved, so that the jade glazed tile has excellent color development effect while achieving the matte effect, and the jade glazed tile has a visual silk or molten luster, and has a delicate touch while achieving the wear resistance, thereby obtaining a jade glazed tile with excellent comprehensive performance.

[0120] When the first frit does not contain ZrSiO4 or does not contain ZnO, the glossiness of the jade glazed tile will decrease, the tile surface is relatively dark, and the touch of the tile surface becomes rough, which is not conducive to the color development of the tile; and when the jade glaze does not contain the second frit and the third frit, the wear resistance of the tile decreases significantly, and the surface flatness decreases, which is not conducive to the improvement of the glossiness of the tile surface.

[0121] From Examples 1, Examples 4-5 and Table 1, it can be seen that by adjusting the mass ratio of zirconium silicate to zinc oxide in the first frit, especially when the mass ratio of zirconium silicate to zinc oxide meets 1:(3.5-4), the wear resistance and delicate touch of the jade glazed tile can be significantly improved, and the jade glazed tile can continue to maintain good matte effect.

[0122] From Examples 1, Example 6, Table 1 and Figures 1-2 , it can be seen that the presence of magnesium oxide in the FGKT frit in the base glaze will affect the color development effect of the jade glazed tile, making the glossiness of the glaze surface too high, and the wear resistance of the glaze surface also decreases slightly.

[0123] From Examples 1, Example 7, Table 1 and Figure 1 、 3 , it can be seen that by adjusting the temperature rising operation in the firing process, the wear resistance of the jade glazed tile in Comparative Example 4 is worse than that of the jade glazed tile in Example 1, and the touch is rough.

[0124] From the above test data, it can be seen that the tile prepared by the glaze composition of the present application can achieve a good balance in terms of glossiness, wear resistance, touch, color development effect and other comprehensive performance, and in the case of achieving the expected glossiness, wear resistance and touch, other performances are also good, which can well meet the quality requirements of the current market for jade glazed tiles.

[0125] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Any simple modification, equivalent change and modification of the above embodiment based on the technical essence of the present application, without departing from the technical solution content of the present application, still belongs to the scope of the technical solution of the present application.
