[0002]平面瓷砖大多数是通过模具来制备网纹效果,但是网纹图案是平面的,而且图案更生硬,而且开模成本高

Benefits of technology

本发明的网纹瓷砖从下到上依次包括:坯底、底釉层、透光釉层、图案层和干粒釉层;其中,底釉层用于提高瓷砖的白度,透光釉可以加强砖面效果,提高质感以及实现透光效果;干粒釉层在烧成后能产生特有的自然纹路,然后形成凸起的立体纹路,从而使得瓷砖的摩擦系数、硬度和耐磨度均有所提升。本发明的瓷砖产品之所以能得到该凸起纹路的原理为:透光釉的熔点低于干粒釉,烧成的时候透光釉先融化,把外层的干粒釉层撑裂,达到透光釉的融化温度时,透光釉从被撑裂的干粒釉层缝隙中涌出,而干粒釉则由于重力作用塌陷,所以透光釉在干粒釉层的表面形成了自然凸起纹路。

Description

Technical Field

[0001] This invention relates to the technical field of ceramic tiles, specifically to a textured ceramic tile and its preparation method. Background Technology

[0002] Most flat ceramic tiles are made using molds to create a mesh effect. However, mesh patterns are flat and rigid, and the mold-making cost is high. Furthermore, the excessive pursuit of overall decorative visual appeal has led to significant safety hazards due to the excessive smoothness of most flat mesh tiles. A common method to improve the anti-slip performance of floor tiles is to use molds or create grooves or stripes on the surface during subsequent processing. However, these types of tiles require further polishing or mold creation, resulting in higher labor and overall costs. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, one objective of this invention is to provide a textured ceramic tile, which uses a combination of a translucent glaze layer with a low melting point and a dry granule glaze layer with a relatively high melting point, and after firing, a textured ceramic tile with raised mesh pattern, high hardness, and high wear resistance is obtained; another objective of this invention is to provide a method for preparing textured ceramic tiles, which does not require mold making, has simple preparation steps, and is suitable for large-scale production.

[0004] One of the objectives of this invention is achieved through the following technical solution: A type of textured ceramic tile, from bottom to top, comprises: a body, a base glaze layer, a translucent glaze layer, a pattern layer, and a dry-granule glaze layer; wherein, the glaze used in the translucent glaze layer comprises the following components by weight percentage: 15-25% aluminum oxide, 30-70% silicon dioxide, 2-6% sodium oxide, 4-8% potassium oxide, 3-7% calcium oxide, 1-5% magnesium oxide, 1-5% boron trioxide, and 2-10% loss on ignition; the dry-granule glaze used in the dry-granule glaze layer is a mixture of a first dry-granule glaze composition and a second dry-granule glaze composition; wherein, the melting point of the first dry-granule glaze composition is lower than the melting point of the second dry-granule glaze composition. The melting point of the translucent glaze layer is lower than that of the dry-granule glaze layer.

[0005] Specifically, the first dry granule glaze composition comprises the following components by weight percentage: 50-70% silicon dioxide, 5-7% aluminum oxide, 5-15% calcium oxide, 1-3% magnesium oxide, 2-5% barium oxide, 5-10% zinc oxide, 2-5% potassium oxide, and 0.2-0.8% sodium oxide; the second dry granule glaze composition comprises the following components by weight percentage: 40-50% silicon dioxide, 20-30% aluminum oxide, 5-10% calcium oxide, 8-15% magnesium oxide, 2-5% potassium oxide, and 1-2% sodium oxide.

[0006] Furthermore, the melting point of the first dry granule glaze composition is 900~940℃, and the melting point of the second dry granule glaze composition is 1100~1150℃.

[0007] Furthermore, the melting point of the translucent glaze layer is 880~920℃, and the melting point of the dry granule glaze layer differs from that of the translucent glaze layer by 100~300℃.

[0008] Furthermore, the glaze used in the base glaze layer includes the following components by weight percentage: 25-35% aluminum oxide, 30-70% silicon dioxide, 3-7% sodium oxide, 4-8% potassium oxide, and 2-10% loss on ignition.

[0009] Furthermore, the amount of glaze applied to the base glaze layer accounts for 30-40% of the total amount; the amount of glaze applied to the translucent glaze layer accounts for 30-40% of the total amount. The total amount of glaze applied is calculated as: base glaze + translucent glaze + dry granule glaze.

[0010] The second objective of this invention is achieved by the following technical solution: The above-mentioned method for preparing textured ceramic tiles includes the following steps: 1) Prepare the glazes for each layer to obtain the base glaze, translucent glaze, and dry granule glaze respectively; 2) Press the bottom layer of the billet and dry it; 3) Apply a base glaze to the unglazed body to obtain the base glaze layer; 4) Apply a translucent glaze over the base glaze layer to obtain a translucent glaze layer; 5) Inkjet printing of patterns onto the translucent glaze layer to obtain the pattern layer; 6) Apply dry granule glaze to the pattern layer to obtain a dry granule glaze layer; 7) The ceramic tile is fired and shaped in a kiln, and then polished to obtain a textured ceramic tile.

[0011] Furthermore, the method for preparing the dry granular glaze includes the following steps: first, mixing the first dry granular glaze composition and the second dry granular glaze composition, then adding a suspending agent and mixing to obtain the dry granular glaze.

[0012] Furthermore, the base glaze is diluted with water to a flow rate of 30-35 seconds and a specific gravity of 1.86-1.90; the translucent glaze is diluted with water to a flow rate of 30-35 seconds and a specific gravity of 1.78-1.83.

[0013] Furthermore, in step 2), the drying temperature is 150~200℃ and the time is 30~60min.

[0014] Further, in step 7), the firing and shaping process is as follows: first, preheat the temperature to 500~600℃, then heat the temperature to 1100~1200℃ for 15~20 minutes, and finally cool the temperature to 500~600℃ for cooling. The total firing and shaping time is 50~55 minutes.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The textured ceramic tile of this invention comprises, from bottom to top: a base, a base glaze layer, a translucent glaze layer, a pattern layer, and a dry-granule glaze layer. The base glaze layer enhances the whiteness of the tile, while the translucent glaze strengthens the surface effect, improves texture, and achieves light transmission. The dry-granule glaze layer, after firing, produces unique natural patterns, forming raised, three-dimensional textures, thereby improving the tile's coefficient of friction, hardness, and wear resistance. The principle behind this raised texture is as follows: the melting point of the translucent glaze is lower than that of the dry-granule glaze. During firing, the translucent glaze melts first, cracking the outer dry-granule glaze layer. When the melting temperature of the translucent glaze is reached, it flows out from the cracks in the dry-granule glaze layer, while the dry-granule glaze collapses due to gravity. Therefore, the translucent glaze forms a natural raised texture on the surface of the dry-granule glaze layer.

[0016] Specifically, the dry granule glaze of the present invention is formed by mixing a first dry granule glaze composition and a second dry granule glaze composition; wherein the melting point of the first dry granule glaze composition is lower than that of the second dry granule glaze composition. At a subsequent firing temperature not exceeding 1200°C, the first dry granule glaze composition will also melt. The location of the melted first dry granule composition will serve as a breakthrough point for the melting and outflow of the translucent glaze layer, while the outer surface of the second dry granule glaze composition will also reach its initial melting point. The second dry granule glaze composition that begins to melt on its outer surface will generate a harder and more wear-resistant substance, thereby causing the molten translucent glaze layer to flow out through the aforementioned breakthrough point, forming natural raised textures.

[0017] (2) The method for preparing the textured ceramic tile of the present invention does not require the use of molds to form raised patterns, nor does it require grooving to improve the anti-slip effect. Specifically, it utilizes the different melting points of translucent glaze and dry granule glaze, and fires them at a temperature not exceeding 1200°C. The translucent glaze melts first, which expands the outer dry granule glaze layer. At the melting temperature of the translucent glaze, the translucent glaze flows out from the gaps in the expanded dry granule glaze layer, while the dry granule glaze collapses due to gravity. Therefore, a natural raised pattern is formed on the surface of the dry granule glaze layer. The pattern formed by this method is more natural, effectively reduces the production cost, and is simple to follow, making it suitable for large-scale production. Attached Figure Description

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Example 1 like Figure 1 As shown, a textured ceramic tile comprises, from bottom to top: a base 1, a base glaze layer 2, a translucent glaze layer 3, a pattern layer 4, and a dry granule glaze layer 5. The translucent glaze layer 3 uses a glaze comprising the following components by weight percentage: 22% aluminum oxide, 51% silicon dioxide, 5% sodium oxide, 6% potassium oxide, 5% calcium oxide, 3% magnesium oxide, 4% boron trioxide, and 4% loss on ignition.

The dry granule glaze layer uses a dry granule glaze composed of a first dry granule glaze composition and a second dry granule glaze composition; wherein the melting point of the first dry granule glaze composition is lower than that of the second dry granule glaze composition. The melting point of the first dry granule glaze composition is 920°C, the melting point of the second dry granule glaze composition is 1155°C, and the melting point of the translucent glaze layer 3 is 950°C.

[0021] Specifically, the first dry granule glaze composition comprises the following components by weight percentage: 60% silicon dioxide, 6% aluminum oxide, 10% calcium oxide, 2% magnesium oxide, 3% barium oxide, 9% zinc oxide, 4% potassium oxide, and 0.5% sodium oxide, with a loss on ignition of 5.5%; the second dry granule glaze composition comprises the following components by weight percentage: 45% silicon dioxide, 29% aluminum oxide, 6% calcium oxide, 10% magnesium oxide, 3% potassium oxide, and 1.5% sodium oxide, with a loss on ignition of 5.5%.

The base glaze layer accounts for 35% of the total glaze amount; the translucent glaze layer accounts for 35% of the total glaze amount. The total glaze amount = base glaze + translucent glaze + dry granule glaze.

[0022] Since this embodiment mainly achieves the raised texture effect through translucent glaze and dry granule glaze, the raw materials of the base glaze will not affect the texture effect, so the raw materials of the base glaze will not be described in detail in this embodiment.

[0023] The above-mentioned method for preparing textured ceramic tiles includes the following steps: 1) Prepare the glazes for each layer to obtain the base glaze, translucent glaze, and dry granule glaze respectively; 2) Press the bottom layer of the blank and dry it at 180℃ for 40 minutes; 3) Apply a base glaze to the bottom of the blank to obtain base glaze layer 2; the standard for glaze application is 75g of material per 300*600mm area. 4) Apply a translucent glaze to the base glaze layer 2 to obtain a translucent glaze layer 3; 5) Print a pattern on the translucent glaze layer 3 by inkjet printing to obtain the pattern layer 4; 6) Apply glaze to pattern layer 4 to obtain dry granule glaze layer 5; 7) The ceramic tile is fired and shaped in a kiln. First, it is preheated to 550℃, then fired at 1150℃ for 17 minutes, and finally cooled to 530℃. The total firing and shaping time is 52 minutes.

The melting point of the first dry granule glaze composition is 900℃, the melting point of the second dry granule glaze composition is 1120℃, and the melting point of the translucent glaze layer 3 is 950℃.

[0027] Specifically, the first dry granule glaze composition comprises the following components by weight percentage: 50% silicon dioxide, 7% aluminum oxide, 15% calcium oxide, 3% magnesium oxide, 2% barium oxide, 5% zinc oxide, 2% potassium oxide, and 0.2% sodium oxide, with a loss on ignition of 15.8%; the second dry granule glaze composition comprises the following components by weight percentage: 40% silicon dioxide, 30% aluminum oxide, 5% calcium oxide, 15% magnesium oxide, 2% potassium oxide, and 1% sodium oxide, with a loss on ignition of 7%. The glaze used in the base glaze layer comprises the following components by weight percentage: 35% aluminum oxide, 60% silicon dioxide, 5% sodium oxide, 5% potassium oxide, and a loss on ignition of 5%. The base glaze layer accounts for 30% of the total glaze amount; the translucent glaze layer accounts for 40% of the total glaze amount. The total glaze amount = base glaze + translucent glaze + dry granule glaze.

[0028] Since this embodiment mainly achieves the raised texture effect through translucent glaze and dry granule glaze, the raw materials of the base glaze will not affect the texture effect, so the raw materials of the base glaze will not be described in detail in this embodiment.

[0029] The above-mentioned method for preparing textured ceramic tiles includes the following steps: 1) Prepare the glazes for each layer to obtain the base glaze, translucent glaze, and dry granule glaze respectively; 2) Press the bottom layer of the billet and dry it at 150℃ for 45 minutes; 3) Apply a base glaze to the bottom layer of the blank to obtain base glaze layer 2; 4) Apply translucent glaze on the base glaze layer 2 to obtain translucent glaze layer 3; Glaze application standard: glaze application amount is 75g per 300*600mm area; 5) Print a pattern on the translucent glaze layer 3 by inkjet printing to obtain the pattern layer 4; 6) Apply glaze to pattern layer 4 to obtain dry granule glaze layer 5; 7) The ceramic tile is fired and shaped in a kiln. First, it is preheated to 500℃, then heated to 1100℃ for 20 minutes, and finally cooled to 500℃. The total firing and shaping time is 50 minutes. After polishing, the textured ceramic tile is obtained.

[0030] The preparation method of the base glaze is as follows: after mixing the raw materials of the base glaze, the flow rate cup test data is 90s, the specific gravity cup data is 1.92, the specific gravity cup slurry fineness is 100 mesh sieve, and the residue is 0.8g.

After diluting with water to 35s, the specific gravity cup data is 1.83. The method for preparing the dry granular glaze includes the following steps: first, mixing a first dry granular glaze composition and a second dry granular glaze composition; then adding a suspending agent and mixing again to obtain the dry granular glaze. The suspending agent includes methylcellulose, bentonite, and a small amount of preservative.

[0031] Example 3 like Figure 1 As shown, a textured ceramic tile comprises, from bottom to top: a base 1, a base glaze layer 2, a translucent glaze layer 3, a pattern layer 4, and a dry granule glaze layer 5. The translucent glaze layer 3 uses a glaze material comprising the following components by weight percentage: 25% aluminum oxide, 42% silicon dioxide, 6% sodium oxide, 8% potassium oxide, 7% calcium oxide, 5% magnesium oxide, 5% boron trioxide, and 2% loss on ignition; the base glaze layer 2 uses a glaze material comprising the following components by weight percentage: 25% aluminum oxide, 66% silicon dioxide, 3% sodium oxide, 4% potassium oxide, and 2% loss on ignition.

[0032] Specifically, the melting point of the first dry granule glaze composition is 900℃, the melting point of the second dry granule glaze composition is 1120℃, and the melting point of the translucent glaze layer 3 is 950℃.

[0033] Specifically, the first dry granule glaze composition comprises the following components by weight percentage: 70% silicon dioxide, 5% aluminum oxide, 10% calcium oxide, 1% magnesium oxide, 2% barium oxide, 8% zinc oxide, 2% potassium oxide, and 0.2% sodium oxide, with a loss on ignition of 2.2%; the second dry granule glaze composition comprises the following components by weight percentage: 50% silicon dioxide, 25% aluminum oxide, 7% calcium oxide, 10% magnesium oxide, 2% potassium oxide, and 1% sodium oxide, with a loss on ignition of 5%. The glaze used in the base glaze layer comprises the following components by weight percentage: 30% aluminum oxide, 55% silicon dioxide, 5% sodium oxide, 6% potassium oxide, and a loss on ignition of 4%. The base glaze layer accounts for 40% of the total glaze amount; the translucent glaze layer accounts for 30% of the total glaze amount. The total glaze amount = base glaze + translucent glaze + dry granule glaze.

[0034] Since this embodiment mainly achieves the raised texture effect through translucent glaze and dry granule glaze, the raw materials of the base glaze will not affect the texture effect, so the raw materials of the base glaze will not be described in detail in this embodiment.

[0035] The above-mentioned method for preparing textured ceramic tiles includes the following steps: 1) Prepare the glazes for each layer to obtain the base glaze, translucent glaze, and dry granule glaze respectively; 2) Press the bottom layer of the billet and dry it at 200℃ for 30 minutes; 3) Spray the base glaze onto the bottom layer of the blank to obtain base glaze layer 2; wherein, the specific gravity cup data is 1.4, and the standard glaze application amount is 100g; 4) Spray a translucent glaze onto the base glaze layer 2 to obtain a translucent glaze layer 3; 5) Print a pattern on the translucent glaze layer 3 by inkjet printing to obtain the pattern layer 4; 6) Apply glaze to pattern layer 4 to obtain dry granule glaze layer 5; wherein, spray glaze: specific gravity cup data 1.4, standard glaze amount: 95g; 7) The ceramic tile is fired and shaped in a kiln. First, it is preheated to 600℃, then heated to 1200℃ for 20 minutes, and finally cooled to 600℃. The total firing and shaping time is 55 minutes. After polishing, the textured ceramic tile is obtained.

[0036] The preparation method of the base glaze is as follows: after mixing the raw materials of the base glaze, the flow rate cup test data is 60s, the specific gravity cup data is 1.88, the specific gravity cup slurry fineness is 100 mesh sieve, and the residue is 0.6g. After diluting with water to 30s, the specific gravity cup data is 1.86. The preparation method of the translucent glaze is as follows: after mixing the raw materials of the translucent glaze, the flow rate cup test data is 60s, the specific gravity cup data is 1.80, the specific gravity cup slurry fineness is 100 mesh sieve, and the residue is 0.4g. After diluting with water to 30s, the specific gravity cup data is 1.78-1.83. The method for preparing the dry granular glaze includes the following steps: first, mixing a first dry granular glaze composition and a second dry granular glaze composition; then adding a suspending agent and mixing again to obtain the dry granular glaze. The suspending agent includes methylcellulose, bentonite, and a small amount of preservative.

[0037] Comparative Example 1 The difference between Comparative Example 1 and Example 1 is that Comparative Example 1 does not contain a translucent glaze.

[0038] Comparative Example 2 The difference between Comparative Example 2 and Example 1 is that Comparative Example 2 does not contain dry granule glaze.

[0039] Performance testing I. Texture Effect Depend on Figures 2-4 It can be seen that the textured tile of Example 1 has both natural and dynamic patterns and raised three-dimensional patterns, while the textured tiles of Comparative Examples 1 and 2, although they have patterns, do not have raised three-dimensional patterns. This indicates that the raised textured effect can only be achieved by combining translucent glaze and dry granule glaze.

[0040] II. Hardness Test Testers conducted Mohs hardness tests on Examples 1-3, Comparative Examples 1-2, and commercially available flat mesh tiles and antique-style ceramic tiles. The manufacturers of the commercially available flat mesh tiles and antique-style ceramic tiles were all Guangdong Wangfu Guoshi Building Materials Co., Ltd. The specific testing method was as follows: 10 standard ceramic tiles with known Mohs hardness were selected, with the following standards: talc grade 1, gypsum grade 2, calcite grade 3, fluorite grade 4, apatite grade 5, feldspar grade 6, quartz grade 7, topaz grade 8, corundum grade 9, and diamond grade 10. The level of hardness at which the tile glaze was damaged was observed in each group, and the hardness was expressed as the measured scratch depth. Specific data are shown in Table 1.

[0041] Table 1. Mohs hardness data for each group Group Mohs hardness / grade Example 1 7 Example 2 7 Example 3 7 Comparative Example 1 5 Comparative Example 2 5 Flat mesh tiles currently on sale 4 Antique-style ceramic tiles currently on sale 6 As shown in Table 1, the Mohs hardness of the ceramic tiles in Examples 1-3 is as high as 7, which is higher than that of the flat mesh tiles and antique tiles sold on the market, and the anti-slip properties are also greatly improved.

[0042] III. Abrasion Resistance Test Testers conducted abrasion resistance tests on Examples 1-3, Comparative Examples 1-2, and commercially available flat textured tiles and antique-style ceramic tiles. The abrasion resistance test of ceramic tiles was mainly conducted according to "Test Methods for Ceramic Tiles Part VII" (GB / T3810.7—2016). The principle is as follows: the abrasion resistance of ceramic tiles is tested by placing an abrasive medium on the glazed surface and rotating it. The abrasion resistance of the ceramic tile samples is then compared with that of the un-abraded samples to evaluate the abrasion resistance. The abrasion resistance grading standards for ceramic tiles are shown in Table 2. The abrasion resistance grading data for each group of products are shown in Table 3.

[0043] Table 2. Ceramic tile abrasion resistance classification Table 3. Abrasion resistance data for each group of ceramic tile products Group Abrasion resistance level / grade Example 1 4 Example 2 4 Example 3 4 Comparative Example 1 3 Comparative Example 2 3 Flat mesh tiles currently on sale 3 Antique-style ceramic tiles currently on sale 3 As shown in Table 3, the wear resistance level of the commercially available flat textured ceramic tiles and antique ceramic tiles all reaches level 3, meeting the requirements for ceramic tile manufacturing. However, the ceramic tile products of Examples 1-3 have a wear resistance level as high as level 4, which is higher than that of Comparative Examples 1-2, indicating that the ceramic tile products of the present invention have a superior anti-abrasion effect.

[0044] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
