Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ceramic tiles, in particular to a relief base color ceramic tile and a preparation method thereof. BACKGROUND

[0002] With the gradual improvement of people's aesthetic, there are many ceramic tiles with network cracks on the market at present. The effect of the cracks on the surface of the ceramic tile highlights the natural feeling of the ceramic tile. However, at the same time, the cracks in the glaze layer on the surface of the ceramic tile have the defects of absorbing dirt, unstable glaze (easy to collapse) and the like. Moreover, the ceramic tile products on the market have a relatively planar and smooth surface, which cannot bring the user a three-dimensional decorative effect, and have poor anti-skid effect, so that people walking on the ceramic tile are easy to slip and fall. SUMMARY

[0003] In order to overcome the defects in the prior art, the present application provides a relief base color ceramic tile and a preparation method thereof.

[0004] The technical scheme adopted by the present application to solve the technical problems is: a relief base color ceramic tile, comprising a body layer, a bottom glaze layer, a transparent glaze layer and a dry particle glaze layer distributed in sequence.

[0005] Among them, by weight,

[0006] The raw materials of the bottom glaze layer include the following components: 20-30 parts of sodium feldspar, 20-40 parts of potassium feldspar, 5-10 parts of kaolin, 10-18 parts of alumina, 5-15 parts of zirconium silicate, 10-30 parts of quartz, 3-6 parts of zinc oxide, and 1-5 parts of calcined talc;

[0007] The raw materials of the transparent glaze layer include the following components: 20-35 parts of sodium feldspar, 20-30 parts of potassium feldspar, 5-10 parts of wollastonite, 2-5 parts of alumina, 5-10 parts of calcined talc, 3-8 parts of kaolin, 5-10 parts of barium carbonate, 5-10 parts of quartz, 10-15 parts of dolomite, and 3-6 parts of zinc oxide;

[0008] The raw materials of the dry particle glaze layer include the following components: 100 parts of glue, 30-50 parts of dry particles, and 10-20 parts of alumina.

[0009] The scheme of the present application is that: by applying multiple glaze layers, using the shrinkage difference between different glaze layers during drying and firing, the dry particle glaze layer naturally generates cracks during the firing process, and at the same time, using the melting temperature difference between the glaze layers, the raw materials of the transparent glaze layer are completely melted during high-temperature firing, the melted glaze fills the cracks, and can prevent stains from adhering to the cracks, thereby solving the stain absorption problem of the existing crack glaze. At the same time, the melted glaze penetrates through the cracks and protrudes out of the surface of the dry particle glaze layer, forming a network-shaped protruding texture on the surface of the dry particle glaze layer. The texture has coarse and fine lines, and the shape is natural, bringing a three-dimensional decorative effect. On the one hand, it can strengthen the structural stability of the glaze layer at the crack, solving the deficiency of easy glaze collapse, on the other hand, the protruding texture can improve the anti-skid effect of the ceramic tile glaze surface.

[0010] It should be noted that the ceramic tile of the present scheme is sequentially distributed from bottom to top as a body layer, a bottom glaze layer, a transparent glaze layer and a dry particle glaze layer.

[0011] Specifically, the dry particles are mixed with glue, and during the firing process, the raw materials of the dry particle glaze layer will form cracks during the drainage process. The size of the dry particle diameter will affect the effect of the cracks, in addition, the size of the dry particle diameter will also affect the roughness and anti-skid performance of the glaze. Preferably, the dry particle diameter is controlled between 60-150 mesh, and the effects are optimal. The surface of the dry particle glaze layer after firing presents a solid color effect, and the texture is relatively natural.

[0012] In order to show the realistic effect of the protruding texture, the raw materials of the transparent glaze layer need to have a low high-temperature viscosity and a small surface tension. Therefore, in the raw material formula of the transparent glaze layer, potassium feldspar and sodium feldspar are introduced as main fluxes to produce liquid glass phase during high-temperature melting, which can promote solid phase reaction and reduce the high-temperature viscosity of the melt. The introduction of K2O and Na2O from potassium feldspar and sodium feldspar and other flux components can form various solid melts (glass phase). K2O and Na2O belong to the intermediate active component of surface tension, and its surface tension characteristic constant value is very small, close to zero, so K2O and Na2O can significantly reduce the surface tension of the transparent glaze layer during melting. Therefore, by introducing potassium feldspar and sodium feldspar to increase the content of K2O and Na2O in the raw materials of the transparent glaze layer, the melting temperature, high-temperature viscosity and surface tension of the transparent glaze layer are reduced, so that the raw materials of the transparent glaze layer can more easily penetrate through the cracks and protrude out of the surface of the dry particle glaze layer during melting, forming protruding texture. Similarly, zinc oxide (ZnO) has good fluxing effect in glaze, which can reduce the high-temperature viscosity of the transparent glaze layer and improve the thermal stability of the product. In addition, zinc oxide can also enhance the color development of the glaze surface and expand the glaze maturity temperature range. The amount of zinc oxide in the transparent glaze layer should not be too much, otherwise it will increase the refractoriness and viscosity of the glaze. At the same time, zinc oxide has a strong crystallization tendency in the glaze melt, and excessive zinc oxide will cause the glaze surface to lose transparency due to crystallization, so the amount of 3-6 parts is better.

[0013] In addition, since the raw material of the dry granular glaze layer has a high melting temperature, the color development is poor, and therefore the raw material of the transparent glaze layer also needs to have strong color development performance. Therefore, barium oxide is introduced by adding barium carbonate, and the barium oxide can increase the refractive index of the glass phase in the glaze, which is beneficial to improve the gloss of the transparent glaze layer. More importantly, the barium oxide does not increase the dispersion of the glass phase, and can enhance the color development of the transparent glaze layer. At the same time, the barium oxide is a good fluxing agent in the glaze, and unlike calcium oxide and magnesium oxide, it has a wider fluxing range. Generally speaking, from 900℃, the barium oxide can play a fluxing role, while the calcium oxide and magnesium oxide have a fluxing effect only above 1100℃. Therefore, the introduction of barium oxide can reduce the viscosity of the raw material of the transparent glaze layer, which is beneficial to the melting of the transparent glaze layer and the melting glaze melts out of the surface of the dry granular glaze layer.

[0014] As a further scheme, the raw material of the dry granule includes the following components by weight: 30-50 parts of potassium feldspar, 2-6 parts of quartz, 3-6 parts of zinc oxide, 7-10 parts of barium carbonate, 10-15 parts of dolomite, 10-15 parts of calcite, and 10-25 parts of alumina.

[0015] Specifically, compared with ordinary dry granules, the dry granules used in the present application need to have a high melting temperature and high-temperature stability, so that there is a certain temperature difference between the dry granules and the raw material of the transparent glaze layer, and the dry granules remain relatively stable at high temperature. Therefore, at high temperature, the dry granules sink under the action of gravity, while the melting glaze of the transparent glaze layer protrudes through the cracks to the surface of the dry granular glaze layer, thereby forming raised lines. Therefore, increasing the content of alumina in the formula can significantly improve the melting temperature and high-temperature stability of the dry granules. The alumina in the dry granules is introduced in the form of potassium feldspar and industrial alumina, etc. Since the content of alumina in potassium feldspar is usually low, and the introduction of potassium feldspar will significantly increase the content of alkali metals such as potassium, which will cause the initial melting point of the dry granules to be too low, resulting in defects such as air bubbles and pinholes in the glaze layer. Therefore, the amount of alumina introduced through potassium feldspar is limited. Therefore, in this scheme, the method of directly introducing calcined alumina powder (1-5 μm) is selected to increase the content of alumina in the dry granule formula.

[0016] As a further scheme, the raw material of the dry granule includes the following components by weight: 30-50 parts of potassium feldspar, 2-6 parts of quartz, 3-6 parts of zinc oxide, 7-10 parts of barium carbonate, 10-15 parts of dolomite, 10-15 parts of calcite, and 10-25 parts of alumina.

[0017] As a further scheme, the raw material of the dry granule includes the following components by weight: 30-50 parts of potassium feldspar, 2-6 parts of quartz, 3-6 parts of zinc oxide, 7-10 parts of barium carbonate, 10-15 parts of dolomite, 10-15 parts of calcite, and 10-25 parts of alumina.

[0018] In addition, a preparation method of a raised color ceramic tile is also disclosed, which is used to prepare the raised color ceramic tile described above, and the preparation method includes the following steps:

[0019] S1, preparing a blank, and applying a base glaze slurry to the blank to obtain a tile body A;

[0020] S2, applying a transparent glaze slurry to the tile body A to obtain a tile body B;

[0021] S3, spraying a functional ink to the tile body B in a pattern, and then drying in a glazing line to obtain a tile body C;

[0022] S4, applying a dry granular glaze slurry to the tile body C to obtain a tile body D;

[0023] S5, sequentially performing high-temperature firing, brushing, and soft polishing on the tile body D to obtain a ceramic tile.

[0024] Specifically, in the preparation method, multiple glazing is performed to form multiple glaze layers. In this process, with the aid of the functional ink, the dry granular glaze layer can be engraved into a corresponding pattern by using micro-sculpture and fine-sculpture functional inks according to a designed pattern, and a raised pattern line can be formed after firing.

[0025] As a further scheme, the raw material components of the transparent glaze layer are selected according to the respective weight parts, mixed uniformly, then water is added, and the mixture is finely ground into a slurry with a mesh size of 320-330, a sieve residue mass percentage of 0.3%-0.5%, and a water content of 28%-32%, and after removing iron by sieving and aging, the transparent glaze slurry is obtained.

[0026] As a further scheme, the raw material components of the dry granular glaze layer are selected according to the respective weight parts, stirred uniformly, and then aged for 2-6 hours to obtain the dry granular glaze slurry.

[0027] As a further scheme, the raw material components of the dry granular glaze layer are selected according to the respective weight parts, stirred uniformly, and then aged for 2-6 hours to obtain the dry granular glaze slurry.

[0028] As a further scheme, in step S1, the specific gravity of the base glaze slurry is 1.80-1.95 g / ml, the flow rate is 30-60 seconds / 100 ml volt cup, and the glazing amount is 400-700 g / m 2 ;

[0029] In step S2, the specific gravity of the transparent glaze slurry is 1.80-1.95 g / ml, the flow rate is 30-60 seconds / 100 ml volt cup, and the glazing amount is 300-500 g / m 2 ;

[0031] As a further solution, in step S5, the high-temperature firing temperature is 1170-1180 DEG C, and the firing time is 60-80 minutes.

[0032] The present application has the following beneficial effects: by applying multiple glaze layers, the shrinkage of different glaze layers during drying and firing is different, cracks naturally occur in the dry granular glaze layer during firing, and the raw materials of the transparent glaze layer are completely melted at high-temperature firing due to the difference in melting temperature between the glaze layers, the melted glaze fills the cracks, and the problem of dirt adhesion to the cracks is solved. Meanwhile, the melted glaze penetrates through the cracks and protrudes from the surface of the dry granular glaze layer, forming a network-shaped protruding texture on the surface of the dry granular glaze layer. The texture has coarse and fine lines and a natural shape, which can not only strengthen the structural stability of the glaze layer at the crack site and solve the problem of easy glaze collapse, but also improve the anti-slip effect of the ceramic tile glaze surface.
