Description

Technical Field

[0001] This invention belongs to the field of ceramic tile technology, specifically relating to a strontium barium blue glaze, ceramic tiles, and their preparation methods. Background Technology

[0002] Kiln-transformed glaze is a unique glaze color formed by applying colored glaze to the body and allowing it to flow and blend naturally during high-temperature firing, such as the sky blue glaze.

[0003] Traditional celadon glaze relies on cobalt blue material (Co3O4 content ≥8%) for high-temperature color development (1280-1320℃), with a firing cycle of >10 hours, resulting in high energy consumption and poor color development; at the same time, it has low wear resistance, poor anti-slip properties, and poor stain resistance.

[0004] Therefore, providing a blue glaze with good color development, high wear resistance, good slip resistance, and good stain resistance has broad application prospects. Summary of the Invention

[0007] Furthermore, the strontium barium blue glaze also includes printing paste, printing oil, and water. The amount of printing paste is 40-60% of the mineral mass, the amount of printing oil is 20-30% of the mineral mass, and the amount of water is 25-35% of the mineral mass (the minerals are albite, kaolin, strontium barium silicate frit, and nano-fluorocarbon cerium ore).

[0008] Furthermore, the preparation method of the strontium barium silicate frit is as follows: mix the raw materials, calcine, quench in water, and crush to obtain the strontium barium silicate frit.

[0009] Preferably, the firing temperature is 1170-1195℃, and the holding time is 5-15 minutes.

[0010] Preferably, the crushed material passes through a 400-500 mesh sieve.

[0011] The present invention provides a ceramic tile, comprising a body and a surface glaze layer and a strontium barium blue glaze layer sequentially attached to the body; the strontium barium blue glaze layer is obtained by high-temperature calcination of the aforementioned strontium barium blue glaze.

[0012] Furthermore, the surface glaze layer is obtained by high-temperature calcination of the surface glaze.

[0013] Preferably, the surface glaze comprises, by weight percentage, the following raw materials: Spodumene: 25-35%, alumina: 1.5-3%, kaolin: 25-35%, quartz: 25-35%, zinc oxide: 5-7%, zirconium dioxide: 4.5-10%, carboxymethyl cellulose: 0.1-0.2%, and sodium tripolyphosphate: 0.3-0.5%.

[0014] Furthermore, a pattern layer is also included between the surface glaze layer and the strontium barium blue glaze layer.

[0016] This invention provides a method for preparing the above-mentioned ceramic tile, comprising the following steps: A surface glaze is applied to the surface of the ceramic body, followed by a strontium barium blue glaze, and then the ceramic tile is fired at a high temperature to obtain the ceramic tile.

[0017] Furthermore, the method for preparing the ceramic tile includes the following steps: S1. The green body is made by pressing conventional ceramic green body raw materials, and after drying, it is ready for use; S2. Wet the dried billet with water so that the surface of the billet contains 5-7% moisture; S3. Prepare the materials according to the weight percentage of each raw material of the glaze, mix the raw materials thoroughly and then ball mill them, and apply them evenly to the blank obtained in step S2, and set aside for use; S4. Apply marble pattern according to inkjet requirements. Apply marble pattern ink to the surface of the glaze layer obtained in step S3 using an inkjet printer to form a marble pattern layer. S5.

[0027] The present invention will be further described below with reference to embodiments.

[0028] The following will clearly and completely describe the concept, specific solutions, and technical effects of the present invention with reference to embodiments, so as to fully understand the purpose, features, and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention. The various technical features in the present invention can be combined interactively without contradicting each other.

[0029] This invention provides a low-temperature fast-firing imitation natural marble strontium barium blue glaze ceramic tile, comprising a body and a surface glaze layer, a marble pattern layer, and a strontium barium blue glaze layer sequentially attached to the body; the surface glaze layer is obtained by firing the surface glaze, and the strontium barium blue glaze layer is obtained by firing the aforementioned strontium barium blue glaze. The surface glaze, expressed as a percentage by weight, includes the following raw materials: Spodumene: 25-35%, alumina: 1.5-3%, kaolin: 25-35%, quartz: 25-35%, zinc oxide: 5-7%, zirconium dioxide: 4.5-10%, carboxymethyl cellulose: 0.1-0.2%, and sodium tripolyphosphate: 0.3-0.5%.

[0030] Strontium barium celadon glaze, expressed as a percentage by weight, comprises the following minerals: Sodium feldspar: 56-66%, kaolinite: 12-18%, barium strontium silicate frit: 20-25%, and nano-fluorocarbon cerium ore: 0.5-1.5%; The strontium barium blue glaze also includes printing paste, printing oil and water. The amount of printing paste is 40-60% of the mass of the mineral material, the amount of printing oil is 20-30% of the mass of the mineral material, and the amount of water is 25-35% of the mass of the mineral material.

[0031] The barium strontium silicate frit comprises the following raw materials by weight percentage: Zinc manganese cobalt aluminum spinel: 20-35%, limestone: 1-8%, lithium carbonate: 25-35%, barium carbonate: 25-35%, strontium carbonate: 5-15%, wollastonite: 3-5%, and zinc oxide: 2-8%.

[0032] The preparation method of the strontium barium silicate frit is as follows: mix the raw materials, calcine (calcine temperature 1170-1195℃, holding time 5-15min), quench with water, crush, and pass through a 400-mesh sieve to obtain the strontium barium silicate frit.

[0033] In this invention, the surface glaze layer can be used to cover the body, which is beneficial to the color development of inkjet marble (marble pattern layer) and plays a role in bonding or linking the body and the strontium barium blue glaze.

[0034] In this invention, the addition of printing paste to the strontium barium blue glaze suspends the dry glaze particles, making them less prone to sedimentation, and disperses them, preventing them from clumping together. This improves the performance of the glaze slurry and facilitates glazing.

[0035] In this invention, the strontium barium blue glaze incorporates strontium barium silicate frit and nano-fluorocarbon cerium ore. During firing, these elements combine to form strontium barium silicate frit crystal nuclei. These nuclei exhibit stable properties, enhanced transparency, and multi-dimensional refraction, resulting in denser, less reflective crystal particles that contribute to slip resistance. This makes the glaze a reinforcing material for marble ceramic tile glazes. Zinc manganese cobalt aluminum spinel is used in this invention to improve slip resistance and color the glaze. Specifically, compared to ordinary ceramic tile slabs, the addition of nano-fluorocarbon cerium ore to the strontium barium blue glaze enhances the slip resistance and stain resistance of the glaze layer.

[0036] In this invention, the strontium barium silicate frit has a melting point of 1175~1190℃, a heat resistance temperature of 1244℃, a Mohs hardness of 6, a tensile strength greater than 6.6GPa, and a tensile elastic modulus greater than 410GPa.

[0037] This invention also provides a method for preparing low-temperature fast-firing strontium barium glaze ceramic tiles that imitate natural marble, comprising the following steps: S1. The green body is made by pressing conventional ceramic green body raw materials, and after drying, it is ready for use; S2. Wet the dried billet with water so that the surface of the billet contains 5-7% moisture; S3. Prepare the materials according to the weight proportions of each raw material in the glaze layer, mix the raw materials thoroughly and then ball mill them, and apply them evenly to the blank obtained in step S2, and set aside for use; S4. Apply marble pattern according to inkjet requirements. Apply marble pattern ink to the surface of the glaze layer obtained in step S3 using an inkjet printer to form a marble pattern layer. S5. Prepare the materials according to the weight percentage of each raw material of strontium barium blue glaze, mix the raw materials thoroughly and then ball mill them, and apply them evenly to the marble pattern layer of the blank obtained in step S4, and set aside for use; S6. The blank obtained in step S5 is subjected to high-temperature calcination in a kiln to obtain a low-temperature fast-fired imitation natural marble strontium barium glaze ceramic tile.

[0038] In step S3, after mixing all the raw materials of the glaze, add water equal to 30% of the weight of the raw materials of the glaze, and ball mill for 20 minutes per 100g. The resulting glaze mixture is then passed through a 100-mesh sieve and set aside for use.

[0039] In step S4, a suitable marble pattern is selected, processed using Photoshop software, and then marble pattern ink is applied to the surface glaze layer using an inkjet printer to obtain the corresponding marble pattern layer.

[0040] In step S5, ball milling is performed for 30-50 minutes per 100g. The resulting strontium barium blue glaze mixture is then passed through a 200-mesh sieve and set aside for later use.

[0041] In step S6, the high-temperature calcination temperature is 1170-1195℃ and the time is 70-80min.

[0042] The raw materials used in the following embodiments and comparative examples are expressed as a percentage by weight, including: White clay: 30%, quartz sand: 20%, potassium sand: 30%, black clay: 5%, sodium sand: 10%, calcite: 5%.

[0043] The main component of nano-fluorocarbon cerium ore is fluorocarbon cerium ore (CeFCO3), in which cerium (Ce) has a +3 oxidation state.

[0044] The zinc-manganese-cobalt-aluminum spinel was purchased from Gongyi Fuquan Refractory Materials Co., Ltd., Fuquan DF1-3. Its main component is magnesium aluminum oxide (MgAl2O4), in which zinc (Zn), manganese (Mn), and cobalt (Co) substitute for some magnesium (Mg) or aluminum (Al) elements through isomorphic substitution. The specific composition may vary depending on the element ratios, resulting in subspecies such as zinc spinel (ZnAl2O4) or cobalt spinel (CoAl2O4).

[0085] The ceramic tiles prepared in Examples 1-4 and Comparative Examples 1-7 were subjected to performance testing, and the relevant results are summarized in Table 1 below.

[0086] Table 1:

[0087] Among them: gloss is measured by a gloss meter when the tiles are freshly fired; brush polishing gloss is measured by a gloss meter after brush polishing the tiles, and the brush polishing treatment is brush polishing by a polishing machine; abrasion resistance is tested by an abrasion resistance tester when the tiles are freshly fired; anti-slip resistance is tested by an anti-slip tester when the tiles are freshly fired; stain resistance is determined by applying an oil-based marker to the surface of the tiles, letting it stand for 20 minutes, rinsing it with water, and evaluating the surface residue according to relevant standards; the higher the stain resistance, the fewer the residue on the tile surface and the better the stain resistance effect; the color depth of the tile surface is measured by a colorimeter (Konica Minolta CM-3700A Plus spectrophotometer) when the tiles are freshly fired.

[0088] From Table 1, we can see that: The ceramic tiles prepared in Examples 1-4 of this invention have a gloss level of 35-38 degrees after firing, with good matting performance; a wear resistance level of 4, with good wear resistance; a slip resistance level of R11, with high slip resistance and obvious slip resistance; a stain resistance level of 5, with good stain resistance; and excellent color development effect.

[0089] In contrast to Example 1, the ceramic tiles prepared with ordinary glaze containing cobalt blue had a gloss level of 60 degrees upon firing, poor matting performance, and strong reflection. Even after brushing and polishing, the gloss level could only be stabilized at a maximum of 30 degrees. The wear resistance level was 2, indicating poor wear resistance. The anti-slip level was R8, indicating a low anti-slip level and poor anti-slip effect. The stain resistance level was only 2, indicating poor stain resistance. The color development effect was also poor.

[0090] In contrast to Example 2, the ceramic tiles prepared with ordinary glaze that lacked nano-fluorocarbon cerium ore and strontium barium silicate frit had a gloss of 55 degrees upon firing, poor matting performance, and strong reflection. Even after brushing and polishing, the gloss could only be stabilized at a maximum of 35 degrees. The wear resistance level was 3, indicating poor wear resistance. The anti-slip level was R9, which was slightly higher and showed a certain anti-slip effect. The stain resistance level was 3, indicating poor stain resistance. The color development effect was also poor.

[0091] In contrast to Example 3, the ceramic tiles prepared with ordinary glaze that does not contain barium strontium silicate frit had a gloss of 61 degrees upon firing, poor matting performance, and strong reflection. Even after brushing and polishing, the gloss could only be stabilized at a maximum of 34 degrees. The wear resistance level was 2, indicating poor wear resistance. The anti-slip level was R9, which is slightly higher and showed a certain anti-slip effect. The stain resistance level was 3, indicating poor stain resistance. The color development effect was also poor.

[0092] In contrast, the ceramic tile prepared with strontium barium blue glaze without nano-fluorocarbon cerium ore had a gloss of 65 degrees upon firing, poor matting performance, and strong reflection. Even after brushing and polishing, the gloss could only be stabilized at a maximum of 33 degrees. The wear resistance level was 2, indicating poor wear resistance. The anti-slip level was R9, which is slightly higher and showed a certain anti-slip effect. The stain resistance level was 3, indicating poor stain resistance. The color development effect was also poor.

[0093] In contrast to Example 5, ceramic tiles prepared by replacing zinc-manganese-cobalt-aluminum spinel in barium strontium silicate frit with cobalt blue produced a kiln-fired tile with a gloss level of 64 degrees, poor matting performance, and strong reflection. Even after brushing and polishing, the gloss level could only be stabilized at a maximum of 36 degrees. The wear resistance level was only 2, indicating poor wear resistance. The anti-slip level was R8, indicating a low anti-slip level and poor anti-slip effect. The stain resistance level was 3, indicating poor stain resistance. The color development effect was also poor.

[0094] In contrast to Example 6, the ceramic tiles prepared by directly adding the raw materials from the barium strontium silicate frit into the barium strontium blue glaze without pre-firing had a gloss level of 66 degrees upon firing, poor matting performance, and strong reflection. Even after brushing and polishing, the gloss level could only be stabilized at a maximum of 35 degrees. The wear resistance level was 2, indicating poor wear resistance. The anti-slip level was R9, which is slightly higher and showed a certain anti-slip effect. The stain resistance level was 3, indicating poor stain resistance. The color development effect was also poor.

[0095] In contrast, the ceramic tile prepared by directly adding zinc manganese cobalt aluminum spinel to strontium barium blue glaze (without adding zinc manganese cobalt aluminum spinel to the strontium barium silicate frit) had a gloss of 65 degrees upon firing, poor matting performance, and strong reflection. Even after brushing and polishing, the gloss could only be stabilized at a maximum of 35 degrees. The wear resistance level was 2, indicating poor wear resistance. The anti-slip level was R9, which is slightly higher and shows a certain anti-slip effect. The stain resistance level was 3, indicating poor stain resistance. The color development effect was also poor.
