Description

Technical Field

[0001] The invention relates to the technical field of ceramics, and in particular to an artistic parquet wood-grain tile and a preparation method thereof. Background Art

[0002] Artistic parquet wood grain tiles are mostly used for floor decoration and wall decoration. They are generally in the upper middle level of the tile product grade and are one of the products selected for some mid-to-high-end decoration. Compared with ordinary wood grain tile products, artistic parquet wood grain tiles are more complex in terms of craftsmanship and technology. Wood grain patterns of different colors and textures are spliced ​​on the surface of the tiles, making the tiles present various novel and beautiful shapes, and the appearance is more high-end and fashionable.

[0003] The artistic parquet wood grain tiles currently popular on the market are simply a simple combination of wood grain patterns of different colors and textures spliced ​​together. Compared with parquet wood floors, the surface three-dimensional texture of existing artistic parquet wood grain tiles is poor, which is difficult to meet the aesthetic requirements and consumption needs of modern people. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an artistic parquet wood-grain tile with good fluorescent effect and a preparation method thereof.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] In a first aspect, the present invention provides an artistic parquet wood grain tile, comprising a brick blank, a glaze layer, and a pattern layer arranged in sequence, wherein the glaze layer has a concave wood grain texture, and the concave wood grain texture is prepared by the repulsive effect of functional ink and water-based glaze slurry;

[0007] The functional ink comprises the following components in parts by weight: 25 to 40 parts of a first frit, 14 to 22 parts of calcined alumina, 35 to 55 parts of an organic solvent, 3 to 8 parts of a dispersant, 2 to 4 parts of an etchant, and 1 to 3 parts of a hydrophobic agent;

[0008] The glaze in the aqueous glaze slurry includes the following components in parts by weight: 25-40 parts of potassium feldspar, 15-35 parts of sodium feldspar, 6-10 parts of calcined kaolin, 6-18 parts of calcined alumina, 4-15 parts of wollastonite, 6-18 parts of barium carbonate, 2-8 parts of strontium carbonate, 3-8 parts of zinc oxide, 3-12 parts of zirconium silicate, and 3-8 parts of second frit.

[0009] The present invention adopts matte glaze, solvent, dispersant, corrosive agent and hydrophobic agent to form a very hydrophobic oily mixture in proportion. The oily mixture can form a low-tension non-polar dense oil film on the surface of the brick, and then a highly polar and non-oleophilic water-based glaze slurry is applied on the surface of the tile with the oil film formed. In the area where the non-polar dense oil film is formed, the water-based glaze slurry is naturally repelled by the non-polar dense oil film, forming a relatively concave wood grain texture.

[0010] Preferably, the first frit comprises the following components in parts by weight: SiO2 55-60%, Al2O3 24-30%, K2O 1-3%, Na2O 2-5%, CaO 2-5%, ZnO 3-8%, BaO 1-3%, and B2O3 1-3%.

[0011] Further preferably, the first frit comprises the following components in mass percentage: SiO2 56.36-58.27%, Al2O3 25.94-27.18%, K2O 1.63-2.73%, Na2O 2.27-3.86%, CaO 2.52-3.22%, ZnO 3.46-4.07%, BaO 1.04-2.81%, and B2O3 1.07-2.49%.

[0012] The first frit used in the present invention has silicon dioxide and aluminum oxide as main components, and is compounded with appropriate amounts of potassium oxide, sodium oxide, calcium oxide, zinc oxide, barium oxide and boron trioxide. The first frit in the functional ink is compounded with calcined aluminum oxide in an appropriate proportion as a glaze component, which can ensure the matte effect of the glaze while improving the high temperature resistance of the glaze, stabilizing the firing temperature of the glaze, and widening the firing range of the glaze.

[0013] Preferably, the functional ink comprises the following components in parts by weight: 30-35 parts of a first frit, 16-18 parts of calcined alumina, 37-42 parts of an organic solvent, 5-7 parts of a dispersant, 3-3.5 parts of a corrosive agent, and 1.5-2 parts of a hydrophobic agent.

[0014] Preferably, the organic solvent includes at least one of triethylene glycol diisooctanoate, isopropyl laurate, isooctyl palmitate and fatty acid methyl ester; further preferably, the organic solvent includes the following components by weight: 35-45 parts of triethylene glycol diisooctanoate, 15-40 parts of isopropyl laurate, 15-35 parts of isooctyl palmitate and 15-25 parts of fatty acid methyl ester. Adding the above solvent to the functional ink can effectively promote the dissolution of the dispersant and the corrosive agent, which is beneficial to the uniform dissolution of each glaze component in the functional ink and ensures the overall uniformity of the functional ink.

[0015] Preferably, the dispersant includes one of sodium tripolyphosphate, sodium hexametaphosphate and sodium pyrophosphate, and its function is to prevent the sedimentation and aggregation of ultrafine particles in the ink and promote the formation of a stable suspension.

[0016] Preferably, the corrosive agent includes at least one of bismuth vanadate, boron trioxide and sodium tetraborate. Bismuth vanadate, boron trioxide and sodium tetraborate are all low melting point compounds. During the high temperature firing process of ceramics, these low melting point compounds melt and volatilize, so that the tiles form a three-dimensional effect of slight corrosion depression.

[0017] Preferably, the hydrophobic agent includes at least one of organosilicon quaternary ammonium salt, fatty alcohol polyoxyethylene ether, and alkyl alcohol ether. Further preferably, the hydrophobic agent includes the following components in parts by weight: 1 to 10 parts of organosilicon quaternary ammonium salt, 1 to 10 parts of fatty alcohol polyoxyethylene ether, 10 to 20 parts of alkyl alcohol ether, and 60 to 88 parts of water. The present invention introduces a compound of organosilicon quaternary ammonium salt, fatty alcohol polyoxyethylene ether, alkyl alcohol ether and water, which can promote the dispersion effect of other components in the ink, form a stable dispersion, and make the functional ink have certain waterproof and hydrophobic properties.

[0018] Preferably, the glaze in the aqueous glaze slurry includes the following components in parts by weight: 28-32 parts of potassium feldspar, 17-20 parts of sodium feldspar, 6-8 parts of calcined kaolin, 6-10 parts of calcined alumina, 6-10 parts of wollastonite, 8-10 parts of barium carbonate, 3-5 parts of strontium carbonate, 4-6 parts of zinc oxide, 5-6 parts of zirconium silicate, and 4-6 parts of the second frit.

[0019] Preferably, the second frit comprises the following components in mass percentage: SiO2 45-55%, Al2O3 8-16%, K2O 3-9%, Na2O 1-3%, CaO 7-13%, MgO 0.5-2%, ZnO 4-8%, BaO 10-16%, and B2O3 2-5%.

[0020] Further preferably, the second frit comprises the following components in mass percentage: SiO2 48.52-51.69%, Al2O3 9.67-10.19%, K2O 4.48-5.08%, Na2O 1.26-2.63%, CaO 7.29-10.68%, MgO 0.93-1.65%, ZnO 5.56-6.52%, BaO 11.42-14.29%, and B2O3 2.11-3.62%.

[0021] The inventors have found through research that by rationally designing the formula of functional ink and the formula of glaze, the firing effect of tiles can be improved, and while ensuring the three-dimensional tactile effect of tiles, the anti-fouling, anti-slip and wear resistance of the tile glaze can be improved.

[0022] Preferably, the artistic parquet wood grain tile also includes a first protective glaze layer, which is covered on the pattern layer. The first protective glaze layer includes the following preparation raw materials in parts by weight: 30 to 55 parts of glaze powder, 40 to 60 parts of solvent, 3 to 7 parts of dispersant, 0 to 3 parts of surfactant, and 0 to 0.5 parts of anti-settling agent.

[0023] Further preferably, the glaze powder includes the following components in parts by weight: 15-30 parts of kaolin, 10-20 parts of illite, 8-16 parts of quartz powder, 6-15 parts of talc, 8-15 parts of dolomite, 3-10 parts of zirconium silicate, 6-10 parts of titanium dioxide, 3-15 parts of barium carbonate, and 0.5-1 part of sodium tripolyphosphate.

[0024] Further preferably, the artistic parquet wood grain tile also includes a second protective glaze layer, and the second protective glaze layer is covered on the first protective glaze layer.

[0025] Further preferably, the second protective glaze layer comprises the following preparation raw materials in parts by weight: 25-35 parts of potassium feldspar, 15-25 parts of sodium feldspar, 10-15 parts of calcined kaolin, 1-4 parts of washed ball clay, 8-15 parts of quartz powder, 5-15 parts of barium carbonate, 2-6 parts of zinc oxide, 10-20 parts of fluorite, 2-6 parts of the third frit, 0.2-0.5 parts of sodium tripolyphosphate, and 0.3-0.6 parts of sodium carboxymethyl cellulose; the third frit and the second frit are the same or different frit powders.

[0026] The present invention provides a double-layer protective glaze layer, which can not only effectively stabilize the color development effect of the wood grain texture color, but also improve various physical properties of the tile, such as anti-fouling, anti-slip and wear resistance.

[0027] Preferably, the pattern layer is formed by pattern ink.

[0028] It is understood that the present invention has no particular restrictions on the color of the pattern ink, and it can be formulated according to the desired wood grain pattern color.

[0136] The difference between this comparative example and Example 1 is that in this comparative example, "30 parts of first melt and 18 parts of calcined alumina" in the raw materials for preparing the texture layer are replaced with "48 parts of glaze", and the glaze has the same formula as the top glaze in step S3 of Example 1.

[0139] Comparative Example 6

[0143] Comparative Example 8

[0144] The difference between this comparative example and Example 1 is that the ceramic tile of this example is not provided with the first protective glaze layer.

[0145] Effect Example 1

[0146] The tiles prepared in Examples 1 to 9 and Comparative Examples 1 to 8 were used as test samples and the following tests were performed:

[0147] (1) Evaluation of three-dimensional touch effect: Invite R&D personnel and tile sales personnel in the industry to form an evaluation team to evaluate the surface of the sample. The evaluation results are given by the evaluation team after discussion. The evaluation team members touch the glaze surface with their hands and divide it into three grades: excellent, medium and inferior. The glaze effect is excellent if it feels close to the real solid wood art parquet floor, with rich three-dimensionality and a strong sense of heaviness; the glaze surface has a slight three-dimensional feeling and is slightly rough, which is medium; the glaze surface is smooth or the glaze surface has obvious transitions and unevenness (giving people an uncomfortable rough feeling), which is inferior;

[0148] (2) Antifouling property: Test in accordance with GB / T3810.14-2016. The staining agent is brought into contact with the glaze surface of the sample and allowed to act for a certain period of time. The sample is then cleaned according to the prescribed cleaning method and the visible changes in the glaze surface of the sample are observed to determine the stain resistance of the sample.

[0149] (3) Anti-slip property: The test is conducted in accordance with GB / T35153-2017. A pendulum with a certain potential energy is swung across the surface of the specimen for a specified distance and then to the other side. The anti-slip property of the specimen surface is evaluated by the potential energy lost by the pendulum in overcoming the frictional resistance of the specimen surface during this process.

[0150] (4) Wear resistance: Tested in accordance with GB / T3810.7-2016. The wear resistance of the glaze is determined by placing abrasive media on the glaze surface and rotating it. The worn samples are compared with the unworn samples to evaluate the wear resistance of the ceramic tile. The samples are divided into Grade 0, Grade 1, Grade 2, Grade 3, Grade 4 and Grade 5.

[0151] The test results are shown in Table 1. The actual photos of the tiles prepared in Example 1 are shown in Table 1. Figures 1-2 shown.

[0152] Table 1

[0153]

[0154] From Table 1 and Figures 1-2 It can be seen that the three-dimensional tactile effect of the tiles prepared in Examples 1 to 9 is close to that of real solid wood artistic parquet flooring, with rich three-dimensionality and a strong sense of thickness, and has excellent anti-fouling, anti-slip and wear resistance. The anti-fouling level reaches level 5 (the highest level), the anti-slip value BPN is greater than the national standard 35, and the wear resistance level reaches level 4.

[0155] Compared with Example 1, in Comparative Example 1, a base glaze layer is formed on the brick blank, and functional ink is printed on the base glaze layer, so that the prepared ceramic tile is smoother, the three-dimensional tactile effect of the ceramic tile is weakened, and the wear resistance is deteriorated.

[0156] Compared with Example 1, the amount of the first frit added to the functional ink used in Comparative Example 2 is too much, so that the firing temperature is lower than the firing temperature of the glaze in the functional ink, which causes the touch of the tile to become noticeably rougher and the anti-fouling performance to be significantly reduced.

[0157] Compared with Example 1, the amount of the first melt added in the functional ink used in Comparative Example 3 is too small, so that the firing temperature is significantly higher than the firing temperature of the glaze in the functional ink, which in turn causes the tile to feel smoother and the anti-slip and wear resistance are significantly reduced.

[0158] Compared with Example 1, the glaze of the functional ink in Comparative Example 4 is the same as the glaze of the water-based glaze slurry, resulting in the tile having a smoother touch, and significantly reduced anti-slip and wear resistance.

[0159] Compared with Example 1, the amount of corrosive agent used in the functional ink of Comparative Example 5 is too much, and too much corrosive agent volatilizes during the firing process, resulting in an overly obvious texture transition on the surface of the tile, giving people an uncomfortable rough feeling, and the anti-fouling performance is significantly deteriorated.

[0160] Compared with Example 1, in Comparative Example 6, the frit in the aqueous glaze slurry of step S3 has the same composition as the first frit in step S2, resulting in poor firing effect, weakened three-dimensional touch of the prepared tiles, and significantly poor anti-fouling performance.

[0161] Compared with Example 1, Comparative Example 7 does not have a second protective glaze layer, and Comparative Example 8 does not have a first protective glaze layer, which results in a weakened three-dimensional touch of the tile, and poor anti-fouling, anti-slip and wear resistance.

[0162] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
