Description

Technical Field

[0001] This invention relates to the field of ceramic tile production technology, and in particular to an ultra-wear-resistant polished glazed tile and its preparation method. Background Technology

[0002] Existing glazed tiles come in a wide variety of colors and patterns, but they are not hard enough and are easily scratched.

[0003] Existing methods for increasing the hardness of glazed tiles typically involve adjusting the glaze formula, significantly increasing the firing temperature, and extending the firing time to enhance the formation and arrangement of mullite crystals, thereby increasing hardness. However, this increases glaze costs and energy consumption, and can also lead to reduced translucency and less vibrant colors, ultimately affecting product quality. Summary of the Invention

[0004] To address the issues of existing methods for increasing the hardness of glazed tiles, which typically involve adjusting the glaze formula, significantly increasing the firing temperature, and extending the firing time, leading to increased glaze costs and energy consumption, as well as reduced transparency and less vibrant colors, this invention provides an ultra-wear-resistant glazed tile and its preparation method. By designing an ultra-wear-resistant glaze formula, the high hardness and wear resistance of the glaze effectively protect the tile from scratches and abrasions. Its high transparency does not obscure the inkjet layer pattern, thus preserving the tile's color and texture. Furthermore, by designing a high-performance wax formula, a wax layer is formed on the surface of the wear-resistant glaze, further enhancing hardness and wear resistance. Its high adhesion and film-forming stability significantly improve the anti-fouling effect of the ultra-wear-resistant glazed tile.

[0005] To achieve the above objectives, the present invention provides an ultra-wear-resistant polished glazed tile, comprising a body and a base glaze layer and an inkjet layer sequentially disposed on the surface of the body, characterized in that: it further comprises a wear-resistant polished glaze layer and a diamond wax layer, wherein the wear-resistant polished glaze layer is made of wear-resistant polished glaze material, and the raw materials for preparing the wear-resistant polished glaze material, based on the total weight of the wear-resistant polished glaze material, include the following components: Potassium sodium feldspar 39-41 parts, washed soil 8-10 parts, calcined kaolin 10-12 parts, wollastonite 5-7 parts, dolomite 15-17 parts, strontium sulfate 5-7 parts, zinc oxide 3-5 parts; The diamond wax layer is obtained by polishing and waxing with DaMoWang diamond wax liquid. Based on the total weight of DaMoWang diamond wax liquid, the raw materials for preparing DaMoWang diamond wax liquid include the following components: The composition includes 10-15% nano-sized corundum powder, 1-3% nano-sized boron nitride, 8-10% nano-sized alkaline silica sol, 6-8% nano-sized platinum-based coupling agent, 0.5-1% organosilicon penetrant, and 63-74.5% deionized water.

[0006] In the wear-resistant polishing glaze formulation of this invention, dolomite decomposes at high temperatures to release magnesium oxide (MgO) and calcium oxide (CaO), enhancing the spreadability of the glaze and forming a smooth and dense glaze layer; wollastonite contains calcium silicates and has a low coefficient of thermal expansion (6.67), significantly reducing the stress on the body and glaze and preventing cracking; its non-volatile properties inhibit firing shrinkage, improving the hardness and wear resistance of the glaze surface; zinc oxide enhances the toughness of the glaze layer, and together with wollastonite, forms a high-hardness surface (Mohs hardness ≥ 6), with scratch resistance superior to traditional formulations; wollastonite and strontium sulfate synergistically reduce the coefficient of thermal expansion of the glaze layer, enhance the glaze-body bonding strength, and reduce the risk of cracking; therefore, dolomite, wollastonite, The synergistic effect of zinc oxide and strontium sulfate can significantly improve the overall hardness and wear resistance of the glaze: potassium-sodium feldspar, as the main flux, can significantly lower the melting point of the glaze and shorten the firing cycle; dolomite (magnesium-calcium source) and wollastonite (calcium-silicon source) further synergistically reduce high-temperature viscosity and improve melt fluidity; zinc oxide, as an amphoteric oxide, further broadens the firing temperature range, effectively reduces high-temperature viscosity, reduces pinholes and "crater" defects in the glaze, and improves the uniformity and smoothness of the glaze layer; therefore, the combined effect of potassium-sodium feldspar, dolomite, wollastonite, and zinc oxide can significantly reduce the firing temperature (1212℃) and shorten the firing time (36min). Strontium sulfate replaces traditional barium carbonate, forming a stable strontium glass phase at high temperatures, significantly improving the gloss of the glaze while reducing the toxicity risks of lead and barium; calcined kaolin, after high-temperature dehydration, has a stable structure and a whiteness of over 93%, significantly improving the hiding power and purity of the base color of the glaze, increasing the suspension of the glaze, and avoiding color differences caused by precipitation. The alkaline earth metal oxides in strontium sulfate and dolomite enhance the glaze's resistance to acid and alkali corrosion, meeting the GLB grade acid and alkali resistance standard. Strontium sulfate (SrSO4) has extremely low solubility (0.014g / 100ml water), contains no volatile harmful substances, and is safer than traditional barium-containing glazes. Washed clay and calcined kaolin work synergistically to provide excellent suspension, preventing glaze slurry sedimentation; their colloidal properties improve rheological properties, making them suitable for various processes such as spray glazing and pour glazing. Therefore, the synergistic effect of strontium sulfate, calcined kaolin, dolomite, and washed clay improves the overall gloss and transparency of the glaze, allowing ultra-wear-resistant polished glazed tiles to maintain their vibrant colors.

[0007] Therefore, wear-resistant polishing glaze has the characteristics of high hardness, high wear resistance, high transparency, and significantly reduced firing temperature.

[0008] The nano-sized corundum powder (α-Al2O3) in the formula of the Da Mo Wang Diamond Wax Water of this invention has a Mohs hardness of 9, which can form a microcrystalline protective layer, significantly improving the scratch resistance of the tile surface. The nano-sized corundum powder also has good chemical stability and can resist the erosion of a variety of chemical substances. Nano-sized boron nitride has high-temperature lubricity (withstanding 2800℃), reduces friction loss, and enhances the self-cleaning property of the coating, making it difficult for stains to adhere. The synergistic effect of nano-sized corundum powder and nano-sized boron nitride can improve the overall wear resistance of the tile by more than 40%. Nano-sized corundum powder can also improve the bonding performance between the wax coating and the tile substrate; the nano-alkaline silica sol in the formula acts as an inorganic binder, with a penetration depth of ≥3mm, forming silicon-oxygen bonds with the tile substrate, and a pull-out adhesion of ≥1.5MPa, which can effectively avoid the problem of easy peeling of traditional wax layers; the nano-sized platinum-based coupling agent can optimize the dispersion of nanoparticles, prevent agglomeration, ensure uniform distribution of components, improve the density of the coating, improve the compatibility of inorganic abrasives and organic phases, prevent component stratification, and improve the adhesion and weather resistance of the wax layer; therefore, the synergistic effect of nano-sized corundum powder, nano-alkaline silica sol and nano-sized platinum-based coupling agent can significantly improve the adhesion and film stability of the wax coating to the tile surface. Organosilicon penetrants can reduce surface tension to ≤30mN / m, allowing wax liquid to quickly fill the micropores (pore size 1~10μm) of ceramic tiles, forming a hydrophobic barrier. The measured waterproof rating reaches IPX7, with no penetration after 72 hours of immersion. Nano boron nitride also enhances chemical corrosion resistance, resists strong acids, strong alkalis and organic solvents, and has a VOC release of ≤0.01mg / m³. The synergistic effect of organosilicon penetrants and nano boron nitride can effectively improve the anti-fouling and hydrophobic properties of the wax layer.

[0009] Therefore, the formula of Da Mo Wang Diamond Wax has high hardness, high wear resistance, high adhesion and film-forming stability, as well as high anti-fouling performance.

[0010] Preferably, the raw materials for preparing the Da Mo Wang diamond wax liquid include the following components: 15% nano-grade corundum powder, 3% nano-grade boron nitride, 10% nano-grade alkaline silica sol, 8% nano-grade platinum-based coupling agent, 1% organosilicon penetrant, and 63% deionized water.

[0011] After multiple trials and wear resistance tests, the above formula components are the optimal formula. When tiles are waxed with this formula, the Mohs hardness of the tiles can reach level 6, which is 170% higher than that of traditional tiles and 40% higher in wear resistance.

[0012] Preferably, the thickness of the wear-resistant polished glaze layer is set to 0.1 to 0.3 mm.

[0013] Preferably, the particle size of the nano-sized corundum powder is set to 50-100 nm.

[0014] Preferably, the thickness of the polishing and waxing layer is set to 0.02 to 0.04 mm.

[0015] This invention also provides a method for preparing the above-mentioned ultra-wear-resistant glazed bricks, characterized by comprising the following steps: (1) The raw materials for preparing the wear-resistant polishing glaze are mixed in proportion and then ball-milled to obtain the wear-resistant polishing glaze, wherein the specific gravity of the wear-resistant polishing glaze is 1.85~1.88g / cm³. 3 ; (2) Mix the raw materials for preparing the Damowang diamond wax water in proportion and stir evenly to obtain the Damowang diamond wax water; (3) Apply a base glaze to the surface of the body to obtain a base glaze layer, and then perform inkjet printing on the surface of the base glaze layer to obtain an inkjet layer; (4) Apply a wear-resistant polishing glaze to the surface of the inkjet layer, wherein the amount of the wear-resistant polishing glaze is 90g / (300mm×600mm tray) to obtain a wear-resistant polishing glaze layer; (5) After drying the blank obtained in step (4), fire it, polish it, and then wax it with the Da Mo Wang diamond wax water prepared in step (2) to obtain an ultra-wear-resistant polished glazed brick with diamond wax layer.

[0016] Preferably, the firing temperature curve in step (5) includes: The initial temperature range is 0–700℃, taking 5 minutes. Medium temperature range: 700–1200℃, time: 6 minutes; High temperature zone: 1200~1212℃, time: 10min; The heat treatment time at 1212℃ is 5 minutes. Rapidly cool to 1000℃ in 10 minutes.

[0017] Preferably, the polishing in step (5) is a flexible mirror polishing, which includes a primary polishing and a secondary hard polishing. The primary polishing uses 72 grinding heads evenly distributed in a rectangular array to polish the surface of the tile, and the secondary hard polishing uses a 9600rpm high-speed drill bit to perform a secondary hard polishing on the surface of the tile.

[0018] Preferably, the inkjet printing in step (3) uses rare stone as a model and utilizes the German CRUSE scanner and the Spanish ARSJZ color system to reproduce the fine texture of natural marble in high definition at a 1:1 ratio.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, through the design of an ultra-wear-resistant polished glaze formula, effectively protects ultra-wear-resistant polished glaze tiles from scratches and abrasions due to its high hardness and wear resistance. Its high transparency does not obscure the inkjet layer pattern, thus preserving the color and texture of the ultra-wear-resistant polished glaze tiles. Furthermore, by designing a high-performance polishing wax formula, a high-performance wax layer is formed on the surface of the wear-resistant polished glaze, further enhancing hardness and wear resistance. Its high adhesion and film-forming stability significantly improve the anti-fouling effect of the ultra-wear-resistant polished glaze tiles. The ultra-wear-resistant polished glaze tiles of this invention achieve a Mohs hardness of 6 or higher, representing a 170% improvement over existing wear-resistant polished glaze tiles. Their wear resistance reaches 4 or higher (9600 revolutions), a 40% improvement over existing wear-resistant polished glaze tiles, and their anti-fouling level reaches 5. This solves the problems of low glaze hardness, poor wear resistance, and easy surface scratching in existing polished glaze tiles. 2. The super wear-resistant polished glaze formula of this invention has the combined effect of potassium sodium feldspar, dolomite, wollastonite and zinc oxide, which can significantly reduce the firing temperature and shorten the firing time. By improving the firing temperature curve, this invention greatly saves firing costs and energy consumption compared with the existing firing process to improve the hardness of polished glaze tiles. Detailed Implementation

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0022] A method for preparing an ultra-wear-resistant glazed tile, characterized by comprising the following steps: (1) The raw materials for wear-resistant polishing glaze are mixed in proportion and then ball-milled to obtain the wear-resistant polishing glaze. The specific gravity of the wear-resistant polishing glaze is 1.85~1.88g / cm³. 3 The raw materials for preparing wear-resistant polishing glaze include the following components: Potassium sodium feldspar 39-41 parts, washed soil 8-10 parts, calcined kaolin 10-12 parts, wollastonite 5-7 parts, dolomite 15-17 parts, strontium sulfate 5-7 parts, zinc oxide 3-5 parts; (2) Mix the raw materials of Damowang diamond wax water in proportion and stir evenly to obtain Damowang diamond wax water. The raw materials for preparing Damowang diamond wax water include the following components: 10-15% nano-grade corundum powder, 1-3% nano-grade boron nitride, 8-10% nano-grade alkaline silica sol, 6-8% nano-grade platinum coupling agent, 0.5-1% organosilicon penetrant, and 63-74.5% deionized water.

[0023] (3) Apply a base glaze to the surface of the body to obtain a base glaze layer, and then perform inkjet printing on the surface of the base glaze layer to obtain an inkjet layer; (4) Apply a wear-resistant polishing glaze to the surface of the inkjet layer, wherein the amount of the wear-resistant polishing glaze is 90g / (300mm×600mm tray) to obtain a wear-resistant polishing glaze layer; (5) After drying the blank obtained in step (4), fire it, polish it, and then wax it with the Da Mo Wang diamond wax water prepared in step (2) to obtain an ultra-wear-resistant polished glazed brick with diamond wax layer.

[0024] It is worth noting that the high hardness and high wear resistance of the ultra-wear-resistant polished glaze in this technical solution can effectively protect the ultra-wear-resistant polished glaze tiles from being scratched and abraded. The high transparency will not cover the pattern of the inkjet layer and will not affect the color and texture of the ultra-wear-resistant polished glaze tiles. By designing the formula of the "Big Grinding King" diamond wax, a diamond wax layer is formed on the surface of the wear-resistant polished glaze layer, which can further improve the hardness and wear resistance. Its high adhesion and film-forming stability can significantly improve the anti-fouling effect of the ultra-wear-resistant polished glaze tiles.

[0025] Preferably, the firing temperature profile in step (5) includes: The initial temperature range is 0–700℃, taking 5 minutes. Medium temperature range: 700–1200℃, time: 6 minutes; High temperature zone: 1200~1212℃, time: 10min; The heat treatment time at 1212℃ is 5 minutes. Rapidly cool to 1000℃ in 10 minutes.

[0026] The super wear-resistant polished glaze formulation of this technical solution has a synergistic effect of potassium sodium feldspar, dolomite, wollastonite and zinc oxide, which can significantly reduce the firing temperature and shorten the firing time. This embodiment improves the firing temperature curve, which greatly saves firing costs and energy consumption compared with the existing firing process to improve the hardness of polished glaze tiles.

[0027] Preferably, the polishing in step (5) is a flexible mirror polishing, which includes a primary polishing and a secondary hard polishing. The primary polishing uses 72 grinding heads evenly distributed in a rectangular array to polish the surface of the tile, and the secondary hard polishing uses a 9600rpm high-speed drill bit to perform a secondary hard polishing on the surface of the tile.

[0028] Specifically, the 72 grinding heads are arranged in a rectangular grid, covering the tile surface without any dead corners. The polishing time for a single tile can be reduced by more than 30%. Each grinding head is equipped with a micro motor, which supports independent adjustment of speed (1000-5000 rpm) and pressure (0.5-2.0 MPa). Through real-time feedback from the pressure sensor, the grinding head can dynamically adjust its height, which can eliminate the flatness error of the tile surface (ensuring the error is within ±0.1mm).

[0029] As a preferred option, the inkjet printing in step (3) uses rare stone as a model and utilizes the German CRUSE scanner and the Spanish ARSJZ color system to reproduce the fine texture of natural marble in high definition at a 1:1 ratio.
