Description

Technical Field

[0001] The invention relates to the field of building ceramics, and in particular to a marble tile with leaf and flower imitation textures and a preparation method thereof. Background Art

[0002] Marble tiles are deeply loved by consumers because of their decorative effect of natural marble simulation and their superior physical and chemical properties. However, their surface effect is mainly glossy, and they lose the texture of the concave and convex texture of the stone surface. When preparing marble tiles with fine leaf and flower textures, the marble tiles prepared by traditional steel molds have a stiff and unnatural concave and convex texture, and it is difficult to achieve the natural texture detail effect of leaves and flowers. Summary of the invention

[0003] The main purpose of the present invention is to propose a method for preparing marble tiles with imitation leaf and flower textures. Through the overall preparation steps and composite texture glaze, it is possible to achieve a natural leaf and flower detail texture effect. The secondary purpose of the present invention is to propose a method for preparing marble tiles with imitation leaf and flower textures.

[0004] To achieve the above object, the present invention provides a method for preparing marble tiles with imitation leaf and flower textures.

[0005] S1, preparing a green body and applying a first glaze;

[0006] S2, digitally printing oil-based ink at positions outside the outline of the leaf and flower patterns to obtain a first pattern layer, applying a second glaze on the brick blank, and forming a digital micro-mold layer on the first pattern layer;

[0007] Inkjet printing of leaf and flower patterns to obtain a second pattern layer, and applying flower glaze coloring on the second pattern layer; the first pattern layer and the second pattern layer can overlap corresponding contours;

[0008] S3, applying a textured glaze at least on the second pattern layer, wherein the raw materials of the textured glaze include the following components in weight percentage: 4-9% columnar olivine, 18-30% quartz, 14-20% borax, 12-16% albite, 4-8% limestone, 5-8% kaolin, 4-7% bauxite, 2-4% chalk, 3-7% mullite and 7-12% dolomite;

[0009] S4, put into kiln for firing.

[0010] The present invention forms a natural digital micro-mold layer in the first pattern layer by applying oily ink between the first glaze and the second glaze and utilizing the drainage property of the oily ink. The digital micro-mold layer refers to the texture effect of micron-level convex and concave on the surface of the blank. The first pattern layer and the second pattern layer overlap to form a natural overall contour. Textured glaze is applied on the second pattern layer where flower glaze is applied for coloring. The columnar olivine (columnar refers to the crystal structure) added to the textured glaze has bands and glass luster, and has different levels of color from green to yellow-green to brown-green. The added alumina-rich columnar stone is rose red. The textured glaze is transparent with different levels of color from light green to yellow-green to rose color, which is helpful for the natural coloring of leaves. The crystal structure is dispersed particles and columnar aggregates, which is beneficial for the presentation of pattern detail texture. The composite textured glaze in the overall process steps can achieve a layered brick surface pattern with a natural overall contour and leaf and flower texture details, which can be clearly distinguished from the rigid texture of the concave and convex texture formed by the bright surface or the steel mold in the prior art.

[0011] Specifically, the first glaze and the second glaze can be made of conventional water-based glaze for marble tiles that does not affect the drainage of oily ink to form textures. In some preferred embodiments, the prepared marble tiles are polished and graded. It can be understood that in order to protect the natural texture of the tile surface, this solution adopts a semi-polishing form. Specifically, the first glaze and the second glaze can be applied in a known manner such as showering, spraying, and screen printing according to actual needs, and are not limited here.

[0012] Preferably, the flower glaze is printed by screen printing in S2, the tension of the screen is 15-18 N / m, the tension ratio of the screen to the flower glaze is 6.5-10:1, and the surface tension of the flower glaze is 1.8-2.3 N / m.

[0013] The tension of existing screens is usually in the range of 19 to 21 N / m. By limiting the lower tension of the screen, a certain tension ratio can be formed with the surface tension of the flower glaze. Combined with the textured glaze, the detailed texture of flowers and leaves can be formed on the second pattern layer, making the resulting marble tile texture more natural.

[0014] Further preferably, the flower glaze includes a first flower glaze, a second flower glaze, a third flower glaze and a fourth flower glaze in the order of screen printing.

[0015] The first flower glaze comprises, by weight: 100 to 105 parts of basic glaze, 4.5 to 6 parts of jadeite green material and 1.0 to 2.5 parts of praseodymium yellow;

[0016] The second flower glaze comprises, by weight: 100 to 105 parts of basic glaze, 12 to 18 parts of grass green material and 3.0 to 7.0 parts of praseodymium yellow;

[0017] The third flower glaze comprises, by weight: 100-105 parts of basic glaze, 15-20 parts of wrapped scarlet, 3.0-7.0 parts of praseodymium yellow and 0.5-2 parts of cobalt blue;

[0018] The fourth flower glaze comprises, by weight: 100-105 parts of basic glaze, 9-12 parts of wrapped scarlet and 1.0-4.0 parts of praseodymium yellow;

[0019] The first glaze, the second glaze, the third glaze and the fourth glaze are all prepared with printing ink substances.

[0020] The basic glaze comprises the following raw materials in percentage by mass: 10-20% potassium feldspar, 15-25% sodium feldspar, 3-11% dolomite, 5-10% wollastonite, 2-5% barium sulfate, 2-6% zinc oxide, 15-20% transparent frit, 8-15% kaolin, 10-15% quartz, 3-5% calcined kaolin and 3-6% trigonal alumina.

[0021] Transparent frit is a common glass material in the industry, which is made by high-temperature melting and has excellent light transmittance. It is mainly composed of albite powder, calcined talc, barium carbonate, zinc oxide, calcite and boric acid. After a specific preparation process, such as hammering, ball milling, drying, screening, pressing, sintering and quenching, a frit with good light transmittance is finally obtained.

[0022] The first and second flower glazes cooperate with the screen with a certain tension difference to produce natural internal detail texture of leaves. The third and fourth flower glazes cooperate with the screen with a certain tension difference to produce natural detail texture of stamens.

[0023] Preferably, the second glaze is an opalescent glaze, and the raw materials of the opalescent glaze include the following components in weight percentage: 13-18% potassium feldspar, 10-20% sodium feldspar, 12-18% quartz, 3-7% ball clay, 9-15% calcined kaolin, 3-4% burned talc, 5-8% kaolin, 1.5-3.5% wollastonite, 7-15% zirconium silicate, 1-3% zinc oxide and 2-4% dolomite powder.

[0024] The second glaze is further preferably an opalescent glaze under this component, which is beneficial to the color development of the overall pattern and the presentation of the texture; and after the composite overall process steps and the textured glaze, it is beneficial to the sufficient oxidation exhaust reaction in the fired oxidation zone, ensuring the glaze quality and avoiding the occurrence of glaze defects.

[0025] More preferably, the specific gravity of the textured glaze is 1.55-1.60 g / ml, and the glaze application amount is 330-650 g / m 2 The specific gravity of the opacified glaze is 1.40-1.48 g / ml, and the glaze application amount is 250-450 g / m 2The above specific gravity and glaze application amount are not only conducive to the application of glaze cabinets, but also can maintain a good glaze decorative effect.

[0026] Further preferably, the oily ink includes deep ink and matte ink, and the weight ratio of deep ink to matte ink is 1:0.5-0.8. This solution adopts the existing oily matte ink and deep ink in the ceramic field, and limits the oily ink to the deep ink and matte ink of the above special weight ratio. The drainage characteristics of the oily ink are used to peel off the protective glaze according to the texture to provide a better mold effect. At the same time, at this weight ratio, the two are not completely cross-fused, so that the light perception changes of matte-light can exist at the same time in the mold. Specifically, the grayscale value of the deep ink and matte ink is 50-90, and the weight ratio between the deep ink and the matte ink is controlled by the grayscale value.

[0027] In a preferred embodiment, the textured glaze comprises the following components by weight percentage: 8% columnar olivine, 28% quartz, 18% borax, 12% albite, 5% limestone, 6% kaolin, 5% bauxite, 3% chalk, 6% mullite and 9% dolomite;

[0028] S2 uses screen printing to apply glaze, the surface tension of the glaze is 2.0N / m, the tension of the screen is 16N / m, and the tension ratio of the screen to the glaze is about 8:1. The oil-based ink is a mixture of engraving ink and matte ink, and the weight ratio of engraving ink to matte ink in the oil-based ink is 1:0.5;

[0029] The second glaze is an opalescent glaze, and the raw materials of the opalescent glaze include the following components in weight percentage: 15% potassium feldspar, 18% sodium feldspar, 17% quartz, 5% ball clay, 13% calcined kaolin, 3% burned talc, 7% kaolin, 3% wollastonite, 10% zirconium silicate, 3% zinc oxide and 4% dolomite powder.

[0030] In this scheme, the performance of the marble tile prepared by the composite overall step and the above-mentioned opaque glaze and textured glaze is optimized.

[0031] Preferably, in S5, the highest firing temperature is 1223°C, and the firing period is 65 to 85 minutes. The above firing system is conducive to the stability of the quality of marble tiles.

[0032] The present invention also provides a marble tile, which is prepared by the preparation method of the marble tile with imitation leaf and flower textures in the above scheme. BRIEF DESCRIPTION OF THE DRAWINGS

[0084] Example 3

[0085] The preparation method of marble tiles comprises the following preparation steps:

[0086] S1. Prepare a green body and apply a first glaze. The chemical composition of the first glaze is shown in Example 1.

[0087] S2, digitally printing oil-based ink at positions outside the outline of the leaf and flower patterns to obtain a first pattern layer, spraying a second glaze on the brick blank to form a digital micro-mold layer on the first pattern layer;

[0088] Inkjet printing of leaf and flower patterns to obtain a second pattern layer, and applying flower glaze coloring on the second pattern layer; the first pattern layer and the second pattern layer can overlap corresponding contours;

[0089] The flower glaze includes a first flower glaze, a second flower glaze, a third flower glaze and a fourth flower glaze in the order of screen printing. The specific composition of the first flower glaze, the second flower glaze, the third flower glaze and the fourth flower glaze can be referred to Example 1.

[0090] S3. Applying textured glaze on the brick, the raw materials of the textured glaze include the following components in weight percentage: 8% columnar olivine, 28% quartz, 18% borax, 12% albite, 5% limestone, 6% kaolin, 5% bauxite, 3% chalk, 6% mullite and 9% dolomite.

[0091] The specific gravity of the textured glaze is 1.58g / ml and the glaze application amount is 500g / m 2 ;

[0092] S4. Firing in kiln, the highest firing temperature is 1223℃, and the firing cycle is 65 to 85 minutes.

[0093] in:

[0094] The second glaze uses the same glaze as the first glaze, with a glaze specific gravity of 1.48g / ml and a glaze application amount of 300g / m2;

[0095] In S2, the glaze is applied by screen printing. The surface tension of the glaze is 2.1N / m, and the tension of the screen is 19N / m. The oily ink is a mixture of engraving ink and matte ink, and the weight ratio of engraving ink to matte ink is 1:1.

[0096] The final product: the overall contour of the first pattern layer has a natural mold concave-convex texture, the second pattern layer has a crystalline structure texture, there is no detailed texture inside the leaves or stamens, the glaze has many pores and depressions and no changes in light perception.

[0097] It can be seen from Examples 1 to 3 that the composite texture glaze basically achieves a layered pattern on the brick surface through the overall process steps, with a natural overall outline, and the crystalline structure texture covering the second pattern layer makes the texture details of the leaves and flowers natural.

[0098] Due to the use of conventional 19-21N / m tension screen, no detailed texture of the inside of leaves and stamens is produced when combined with flower glaze. Conventional glaze and texture glaze are combined to produce certain glaze surface defects such as pores and depressions. A single deep ink or matte ink, or a 1:1 mixture of deep ink and matte ink, will produce uniform and unchanged light perception.

[0099] Example 4

[0100] The raw material composition, process steps and process parameters of the marble tiles are all referred to Example 3. The glaze tension of Example 3 is 2.1N / m. The difference lies in: the tension of the screen.

[0101] The tension of the screen in the specific embodiment of Example 4 is shown in the following table.

[0102]

[0103]

[0104] Effect table

[0105]

[0106] By comparing Example 3 and Example 4-1 to Example 4-4, it can be seen that when textured glaze is used and a screen with a tension of 15 to 18 N / m is combined with the flower glaze, detailed textures of the inside of leaves and stamens are formed; when a conventional screen with a tension of 19 to 21 N / m is used in combination with the flower glaze, the screen tension is large, resulting in a tension ratio with the surface tension of the flower glaze that is too large, the tensile stress of the screen is large when the screen is lifted, and the contact time with the flower glaze is too short, and the detailed textures of the inside of leaves and stamens cannot be formed; when the screen tension is 12 N / m, the screen tension is too low, resulting in a tension ratio with the surface tension of the flower glaze that is too small, the tensile stress of the screen is small when the screen is lifted, and the contact time with the flower glaze is too long, the flower glaze will become a mass, and a clear and fixed texture cannot be formed, and the detailed textures of the inside of leaves and stamens cannot be formed. It can be seen that the screen tension needs to be kept within an appropriate range. Through experiments similar to the present embodiment, it was found that when the screen tension is in the aforementioned range of 15 to 18 N / m, the tension ratio of the screen to the glaze is 6.5 to 10:1, and the surface tension of the glaze is 1.8 to 2.3 N / m, when combined with the textured glaze, the glaze surface forms a natural texture of the interior of leaves and details of stamens.

[0107] Example 5

[0108] The raw material composition, process steps and process parameters of the marble tile are all referred to Example 3, except that: the second glaze adopts an opalescent glaze, and the raw materials of the opalescent glaze include the following components in weight percentage: 15% potassium feldspar, 18% sodium feldspar, 17% quartz, 5% ball clay, 13% calcined kaolin, 3% burned talc, 7% kaolin, 3% wollastonite, 10% zirconium silicate, 3% zinc oxide and 4% dolomite powder.

[0109] The final product: the first pattern layer has a natural mold concave-convex texture on the overall contour, the second pattern layer has a crystalline structure texture, no detailed texture of the inside of the leaves or stamens, no glaze defects and no changes in light perception.

[0110] From the comparison between Example 3 and Example 5, it can be seen that the use of opaque glaze can significantly improve the glaze quality of the product when combined with the textured glaze compared to the conventional glaze.

[0111] Example 6

[0112] The raw material composition, process steps and process parameters of the marble tiles are all referred to Example 3, except that oil-based inks with different weight ratios of deep-engraving ink:matte ink are used.

[0113] The weight ratio of deep ink:matte ink of the oil-based ink of Example 6 is shown in the table below.

[0114] Serial number Deep ink:matte ink weight ratio Example 6-1 1:0.1 Example 6-2 1:0.5 Example 6-3 1:0.8 Example 3 1:1

[0115] Effect table

[0116]

[0117] By comparing Example 3 with Examples 6-1 to 6-3, it can be seen that when the weight ratio of engraving ink:matte ink is 1:0.5-0.8, the obtained product forms a better mold concave and convex texture effect in the digital micro-mold layer, and there is a matte-gloss light perception change. When the weight ratio of engraving ink:matte ink is 1:0.1, the engraving ink content is too high and the matte ink content is too little, and no light perception change can be formed; when the weight ratio of engraving ink:matte ink is 1:1, the contents of engraving and matte inks are close, and the cross-fusion reaction of the two is obvious, and the light perception formed is uniform, without light perception change. It can be seen that in order to achieve the matte-gloss light perception change, the weight ratio of engraving ink:matte ink needs to be kept in an appropriate range.

[0118] Example 7

[0119] The preparation method of marble tiles comprises the following preparation steps:

[0120] S1. Prepare a green body and apply a first glaze. The chemical composition of the first glaze is shown in Example 1.

[0121] S2, digitally printing oil-based ink at positions outside the outline of the leaf and flower patterns to obtain a first pattern layer, spraying a second glaze on the brick blank to form a digital micro-mold layer on the first pattern layer;

[0122] Inkjet printing of leaf and flower patterns to obtain a second pattern layer, and applying flower glaze coloring on the second pattern layer; the first pattern layer and the second pattern layer can overlap corresponding contours;

[0123] The flower glaze includes a first flower glaze, a second flower glaze, a third flower glaze and a fourth flower glaze in the order of screen printing. The specific composition of the first flower glaze, the second flower glaze, the third flower glaze and the fourth flower glaze can be referred to Example 1.

[0124] S3. Applying textured glaze on the brick, the raw materials of the textured glaze include the following components in weight percentage: 8% columnar olivine, 28% quartz, 18% borax, 12% albite, 5% limestone, 6% kaolin, 5% bauxite, 3% chalk, 6% mullite and 9% dolomite.

[0125] The specific gravity of the textured glaze is 1.58g / ml and the glaze application amount is 500g / m 2 ;

[0126] S4. Firing in kiln, the highest firing temperature is 1223℃, and the firing cycle is 65 to 85 minutes.

[0127] The second glaze uses opalescent glaze with a specific gravity of 1.48g / ml and a glazing amount of 300g / m2. The raw materials of the opalescent glaze include the following components in weight percentage: 15% potassium feldspar, 18% sodium feldspar, 17% quartz, 5% ball clay, 13% calcined kaolin, 3% burned talc, 7% kaolin, 3% wollastonite, 10% zirconium silicate, 3% zinc oxide and 4% dolomite powder.

[0128] S2 uses screen printing to apply glaze, the surface tension of the glaze is 2.0N / m, the tension of the screen is 16N / m, and the tension ratio of the screen to the glaze is about 8:1. The oil-based ink is a mixture of deep ink and matte ink, and the weight ratio of deep ink to matte ink in the oil-based ink is 1:0.5.

[0129] The final product: the overall contour of the first pattern layer has a natural mold concave-convex texture, the second pattern layer has a crystalline structure texture, and there are detailed textures of the inside of leaves and stamens, without glaze defects and changes in bright matte feel. Example 7 is the most preferred example.

[0130] Comparative Example 1

[0131] The raw material composition, process steps and process parameters of the marble tiles are all referred to Example 3, except that: conventional transparent glaze is used in S3 instead of textured glaze, and the raw materials or chemical composition of the conventional transparent glaze include, by mass percentage / mass fraction: quartz 28%, borax 12%, albite 15%, limestone 5%, kaolin 12%, bauxite 5%, chalk 3%, potassium feldspar 15% and dolomite 5%.

[0132] The final product: the overall contour of the first pattern layer has a natural mold concave and convex texture, the second pattern layer has no crystalline structure texture, no detailed texture of the inside of the leaves and stamens, the glaze has many depressions and no light changes.

[0133] Comparative Example 2

[0134] The preparation method of marble tiles comprises the following preparation steps:

[0135] S1. A green body is prepared by using a steel mold, and a first glaze is applied. The chemical composition of the first glaze is as shown in Example 1.

[0136] S2, inkjet printing conventional water-based ink to obtain the overall outline and flower and leaf patterns, and applying flower glaze on the flower and leaf patterns by screen printing. The specific flower glaze tension, screen tension, and screen and flower glaze tension ratio refer to Example 3;

[0137] S3, applying textured glaze on the brick, specifically referring to S3 in Example 3;

[0138] S4, firing in a kiln, refer to S4 in Example 3 for details.

[0139] The final product: the first pattern layer has a rigid mold concave-convex texture on the overall outline, the second pattern layer has a crystalline structure texture, which produces detailed textures of the inside of leaves and stamens, and the glaze has many depressions and no changes in light perception.

[0140] By comparing Example 3 with Comparative Examples 1 and 2, it can be seen that the use of conventional transparent glaze is not helpful for the presentation of detailed textures, and the prior art uses steel molds and conventional aqueous ink jet printing, and the resulting overall contour of the mold has a stiff concave-convex texture. Both fail to achieve a layered brick surface pattern similar to that in Example 3, with a natural overall contour and leaf and flower texture details. It can be seen that the overall process steps of this application and the texture glaze are indispensable.

All equivalent structural changes made by using the contents of the present invention specification under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
