A bright surface countertop panel and method of making the same

Abstract

The application discloses a bright surface table board and a preparation method thereof, and relates to the field of table board manufacturing. The steps include grinding, spraying zirconium white glaze, spraying bright glaze, spraying glue, spraying dry particles, firing and polishing the four edges. In the preparation method of the bright surface table board, the zirconium white glaze and the bright glaze are dried in time after being applied, so that the water content of the whole bright surface table board is reduced. In combination with the adjustment of the components of the zirconium white glaze and the bright glaze, the problem that the edge cracks due to the evaporation of water in the edge during firing caused by the excessive water content of the blank is avoided. In addition, the dry glaze particles are sprayed instead of directly spraying glaze, and exhaust channels are formed between the dry glaze particles, so that the bright surface table board smoothly discharges bubbles during firing, and the problem of interlayer bubble aggregation caused by the large-area and multi-layer glazing of the table board is solved.

Description

Technical Field

[0001] This invention relates to the field of tabletops, and more particularly to a glossy tabletop and its preparation method. Background Technology

[0002] Resin composite countertops are made from stone or fiber as aggregate and resin as binder, through processes such as mixing, vacuum pressure vibration molding, and curing. Due to their excellent properties such as high temperature resistance, corrosion resistance, and ease of cleaning, resin countertops are widely used in furniture countertops, kitchen islands, and dining table tops.

[0003] However, during long-term use, the unsaturated double bonds and ester bonds in the unsaturated polyester and epoxy resins of existing resin composite countertops are prone to degradation under ultraviolet light and heat-oxidation, causing the countertop to gradually yellow and discolor. This is especially noticeable on light-colored or white countertops after 1-2 years of use, severely affecting the appearance. Moreover, the interfacial bonding force between the resin and aggregate gradually weakens over time. Affected by temperature and humidity changes, the surface resin layer is prone to peeling off from the aggregate, resulting in flaking. In severe cases, the resin may peel off completely, exposing the internal aggregate layer, which affects both aesthetics and performance, severely restricting the lifespan and appearance retention of resin composite countertops.

[0004] To avoid the drawbacks of resin composite countertops, ceramic countertops have emerged in the existing technology. However, during the preparation of these countertops, the edges of the blank need to be polished to form rounded corners. This polishing process requires water to be sprayed onto the blank for cooling, which increases the moisture content of the blank. During subsequent firing, the edges of the blank are prone to cracking due to stress concentration caused by localized moisture evaporation, severely affecting the yield and production cost. Summary of the Invention

[0005] The purpose of this invention is to provide a glossy tabletop panel and its preparation method to solve the problem that the tabletop panel is prone to edge cracking during the polishing process.

[0006] To achieve this objective, the present invention adopts the following technical solution: This invention provides a method for preparing a glossy tabletop panel, comprising the following steps: Polishing and rounding the blank: Polish the outer edge of the blank to form a rounded edge, thus obtaining a polished blank; Zirconium white glaze spraying: Zirconium white glaze is applied to the surface of the polished body and dried to obtain a body with zirconium white glaze; Spraying glossy glaze: Applying glossy glaze to the surface of a zircon white glaze body and drying it to obtain a glazed body; Spraying glue: Spraying glue onto the surface of the glazed body to form a glue layer; Spraying dry granules: Applying dry glaze granules to the surface of the adhesive layer to obtain the blank to be fired; Firing: The blank to be fired is fired at a temperature of 925-940℃ for a period of 100-150 minutes to obtain a firing table. Grinding and polishing: First, grind and polish the edges of the fired tabletop, then grind and polish the surface of the fired tabletop to obtain a glossy tabletop.

[0007] In the method for preparing the glossy tabletop, between the steps of spraying glossy glaze and spraying adhesive, there is also a step of setting a textured pattern. The step of setting a textured pattern includes: spraying a textured pattern onto the surface of the glaze blank and drying it.

[0008] In the preparation method of the glossy tabletop, the drying temperature is 160-180℃ in the steps of spraying zircon white glaze, spraying glossy glaze and setting textured patterns.

[0009] In the preparation method of the glossy tabletop, the blank body comprises the following components by weight: 15-25 parts of clay, 8-15 parts of kaolin, 8-15 parts of potassium feldspar, 15-25 parts of sodium feldspar, 5-10 parts of wollastonite, 5-10 parts of calcined talc, 8-15 parts of boron-containing frit, and 3-8 parts of quartz.

[0010] In the preparation method of the glossy tabletop, the zircon white glaze comprises the following components by weight: 1.5-3 parts sodium oxide, 0.5-2 parts potassium oxide, 0.5-2 parts magnesium oxide, 1-3 parts calcium oxide, 0.5-2 parts zinc oxide, 0.5-2 parts barium oxide, 0.5-2 parts aluminum oxide, 2-4 parts boron trioxide, 3-5 parts silicon dioxide, and 2-4 parts zirconium dioxide.

[0011] In the preparation method of the glossy tabletop, the glossy glaze comprises the following components by weight: 0.5-2 parts sodium oxide, 0.5-2 parts potassium oxide, 0.5-2 parts magnesium oxide, 1-3 parts calcium oxide, 1-3 parts zinc oxide, 1-3 parts barium oxide, 1-3 parts aluminum oxide, 1-3 parts boron trioxide and 3-5 parts silicon dioxide.

[0012] In the preparation method of the glossy tabletop, the dry glaze particles, by weight, include the following components: 8-15 parts quartz powder, 12-22 parts albite, 15-28 parts calcium feldspar, 5-12 parts calcite, 10-20 parts boron-containing frit, 5-10 parts calcined talc, 5-12 parts zinc oxide, 3-7 parts barium carbonate, 2-5 parts aluminum oxide, and 2-6 parts strontium carbonate.

[0013] In the preparation method of the glossy tabletop panel, the particle size distribution of the dry glaze particles is 60-120 mesh.

[0014] The present invention also provides a glossy tabletop panel, which is prepared by the above-described method for preparing a glossy tabletop panel.

[0015] One technical solution of the present invention can have the following beneficial effects: In the preparation method of the glossy tabletop, after applying zircon white glaze and glossy glaze, the surface is dried in time to reduce the overall moisture content of the glossy tabletop. In addition, the composition of zircon white glaze and glossy glaze is adjusted to avoid excessive moisture content in the body, which would cause edge cracking due to moisture evaporation during firing. Furthermore, dry glaze particles are sprayed instead of directly sprayed, and the dry glaze particles form air venting channels, allowing air bubbles to be smoothly discharged during the firing process of the glossy tabletop, thus solving the problem of interlayer air bubble accumulation caused by large-area, multi-layer glazing of the tabletop. Detailed Implementation

[0016] The technical solution of the present invention will be further illustrated below through specific embodiments. To facilitate understanding of the present invention, a more comprehensive description is provided below. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of the present invention.

[0017] Where specific techniques or conditions are not specified in the examples, they shall be performed in accordance with the techniques or conditions described in the literature in this field or in accordance with the product instructions. Reagents or instruments whose manufacturers are not specified are all commercially available conventional products.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] This invention provides a method for preparing a glossy tabletop panel, comprising the following steps: Polishing and rounding the blank: Polish the outer edge of the blank to form a rounded edge, thus obtaining a polished blank; Zirconium white glaze spraying: Zirconium white glaze is applied to the surface of the polished body and dried to obtain a body with zirconium white glaze; Spraying glossy glaze: Applying glossy glaze to the surface of a zircon white glaze body and drying it to obtain a glazed body; Spraying glue: Spraying glue onto the surface of the glazed body to form a glue layer; Spraying dry granules: Applying dry glaze granules to the surface of the adhesive layer to obtain the blank to be fired; Firing: The blank to be fired is fired at a temperature of 925-940℃ for a period of 100-150 minutes to obtain a firing table. Grinding and polishing: First, grind and polish the edges of the fired tabletop, then grind and polish the surface of the fired tabletop to obtain a glossy tabletop.

[0020] In the production of ceramic countertops, the edges of the ceramic body need to be polished to form rounded corners. This polishing process increases the moisture content at the edges of the body. During subsequent firing, the edges with high moisture content are prone to cracking due to stress concentration caused by localized moisture evaporation.

[0021] In the preparation method of the glossy tabletop, after applying zircon white glaze and glossy glaze, the surface is dried in time to reduce the overall moisture content of the glossy tabletop. In addition, the composition of zircon white glaze and glossy glaze is adjusted to avoid excessive moisture content in the body, which would cause edge cracking due to moisture evaporation during firing. Furthermore, dry glaze particles are sprayed instead of directly sprayed, and the dry glaze particles form air venting channels, allowing air bubbles to be smoothly discharged during the firing process of the glossy tabletop, thus solving the problem of interlayer air bubble accumulation caused by large-area, multi-layer glazing of the tabletop.

[0022] Zirconium white glaze contains zirconium dioxide, and the difference in refractive index of zirconium dioxide causes light scattering, giving the body a super white effect and effectively covering the color of the body.

[0023] During the polishing process, the radius R of the rounded edge is 3 to 8 mm.

[0024] Specifically, between the steps of spraying glossy glaze and spraying adhesive, there is also a step of setting a textured pattern, which includes: spraying a textured pattern onto the surface of the glaze blank and drying it.

[0025] Using an inkjet printer, textured patterns are sprayed onto the surface of the glazed body and dried at 160–180°C. The textured patterns include stone-like and wood-like patterns. Zirconia white glaze covers the base color of the body, and combined with the textured patterns, the countertop exhibits a decorative effect similar to stone or wood, enhancing its appearance.

[0026] Specifically, the drying temperature is 160–180°C in the steps of spraying zircon white glaze, spraying glossy glaze, and setting textured patterns.

[0027] After spraying zircon white glaze, spraying glossy glaze, and setting textured patterns, drying is performed to further reduce the moisture content of the body and reduce edge cracking.

[0028] Specifically, the blank body comprises the following components by weight: 15-25 parts of ball clay, 8-15 parts of kaolin, 8-15 parts of potassium feldspar, 15-25 parts of sodium feldspar, 5-10 parts of wollastonite, 5-10 parts of calcined talc, 8-15 parts of boron-containing frit, and 3-8 parts of quartz.

[0029] The chemical composition of the boron-containing molten metal, by mass percentage, includes 25–35% SiO2, 12–22% B2O3, 8–15% Na2O, 4–10% CaO, 2–8% ZnO, 2–6% BaO, 3–8% Al2O3, 2–6% K2O, and 1–4% MgO.

[0030] Boron-containing frit is introduced into the body, where boron trioxide, sodium oxide, and potassium oxide form a eutectic liquid phase at 925–940℃, achieving low-temperature vitrification and dense, complete vitrification. This results in low water absorption, reducing moisture absorption during polishing. Wollastonite and calcined talc introduce calcium oxide and magnesium oxide, lowering the coefficient of thermal expansion and generating cordierite microcrystals during firing, improving the brick's resistance to temperature differences and reducing heat deformation of the countertop. The total amount of clay and kaolin is 23–40 parts, lower than the amount of clay used in traditional ceramic bodies, reducing the bound water content and further lowering the risk of cracking caused by moisture evaporation at the edges after polishing. The boron-containing frit allows for complete vitrification at 925–940℃, avoiding thermal expansion mismatch and deformation problems caused by conventional high-temperature firing at 1150–1250℃.

[0031] Specifically, the zircon white glaze comprises, by weight, the following components: 1.5-3 parts sodium oxide, 0.5-2 parts potassium oxide, 0.5-2 parts magnesium oxide, 1-3 parts calcium oxide, 0.5-2 parts zinc oxide, 0.5-2 parts barium oxide, 0.5-2 parts aluminum oxide, 2-4 parts boron trioxide, 3-5 parts silicon dioxide, and 2-4 parts zirconium dioxide.

[0032] Zirconium dioxide in zirconium white glaze has a high refractive index, providing the glaze layer with high whiteness and hiding power, effectively covering the base color of the body; boron trioxide, sodium oxide, and potassium oxide work together to lower the melting temperature of the glaze, ensuring that the zirconium white glaze fully melts and bonds with the body at a low temperature of 925-940℃; zinc oxide and barium oxide reduce the high-temperature viscosity of the glaze and promote the smoothness of the glaze surface; when the zirconium white glaze is applied, the glaze slurry penetrates and fills these micro-defects, eliminating stress concentration sources.

[0033] After the zirconium white glaze is applied and dried, a dense glaze layer forms at the edge of the body, preventing subsequent glossy glazes, textured patterns, and other moisture-containing slurries from directly contacting the exposed body and reducing water absorption at the body edge. The components work synergistically to achieve a zirconium white glaze layer with high whiteness and strong hiding power at low temperature firing, providing a clear background for textured patterns.

[0034] Specifically, the glossy glaze comprises, by weight, the following components: 0.5-2 parts sodium oxide, 0.5-2 parts potassium oxide, 0.5-2 parts magnesium oxide, 1-3 parts calcium oxide, 1-3 parts zinc oxide, 1-3 parts barium oxide, 1-3 parts aluminum oxide, 1-3 parts boron trioxide, and 3-5 parts silicon dioxide.

[0035] The glossy glaze contains high levels of zinc oxide and barium oxide, both of which have high refractive indices. After polishing, it imparts a high gloss to the glaze surface, fundamentally replacing the organic gloss layer of resin composite countertops and avoiding aging defects such as yellowing, peeling, and flaking caused by resin oxidation. Boron trioxide, along with sodium oxide and potassium oxide, works synergistically to lower the melting temperature of the glaze, allowing the glossy glaze to fully melt at a low temperature of 925–940℃, avoiding thermal expansion mismatch and deformation problems caused by conventional high-temperature firing at 1150–1250℃. Aluminum oxide controls the high-temperature viscosity of the glaze, preventing glaze flow during low-temperature rapid firing and ensuring the smoothness of the glaze surface.

[0036] Specifically, the dry granules of the glaze, by weight, comprise the following components: 8-15 parts quartz powder, 12-22 parts albite, 15-28 parts calcium feldspar, 5-12 parts calcite, 10-20 parts boron-containing frit, 5-10 parts calcined talc, 5-12 parts zinc oxide, 3-7 parts barium carbonate, 2-5 parts aluminum oxide, and 2-6 parts strontium carbonate.

[0037] Boron-containing flocs are introduced into the dry glaze particles. Boron trioxide, along with sodium feldspar and calcite, synergistically lowers the glaze melting temperature, ensuring a fully melted, glossy glaze surface is formed at a low temperature of 925–940℃. This avoids the thermal expansion mismatch and deformation problems caused by conventional high-temperature firing at 1150–1250℃. After the dry particles are sprayed, exhaust channels are formed between the particles, allowing interlayer air to be smoothly discharged during firing, avoiding interlayer bubble defects caused by direct glaze spraying. During firing, calcium feldspar precipitates microcrystals, reducing the thermal expansion coefficient of the glaze layer and improving the thermal expansion matching between the glaze and the body. The high refractive index of barium oxide in barium carbonate improves the gloss of the glaze surface after polishing.

[0038] Specifically, the dry glaze particles have a particle size distribution of 60–120 mesh.

[0039] The particle size is not less than 60 mesh, so that there is enough gap between the dry glaze particles to form an effective air venting channel, and the interlayer air is smoothly discharged during firing, avoiding bubble defects; the particle size is not higher than 120 mesh, so that the glaze surface is flat and smooth after polishing, avoiding the unevenness of the surface after polishing due to excessively coarse particles.

[0040] Specifically, in the firing step, the firing temperature is 925–940°C, and the firing cycle is 100–150 min.

[0041] The difference in thermal expansion between the body and zirconium white glaze and glossy glaze is small, resulting in low thermal stress. The firing temperature is lower than the conventional 1150-1250℃, significantly reducing the risk of edge cracking and panel deformation. The 100-150min rapid firing cycle shortens the high-temperature softening time of the body, resulting in a low warpage rate. Furthermore, the glaze is fully melted and formed under the assistance of boron-containing frit, ensuring the quality of the glossy surface.

[0042] The present invention also provides a glossy tabletop panel, which is prepared by the above-described method for preparing a glossy tabletop panel. Example 1

[0046] Comparative Example 1 The difference from Example 1 is that the step of spraying zircon white glaze is omitted, and glossy glaze is sprayed directly, while the other steps are the same.

[0047] Comparative Example 2 The difference from Example 1 is that after the glossy glaze spraying step, instead of spraying dry granules, a layer of glaze slurry with the same composition as the dry granules is sprayed directly onto the adhesive layer, and the remaining steps are the same.

[0048] Comparative Example 3 The difference from Example 1 is that the firing temperature is increased to 1200°C and the firing cycle is 60 minutes, while the other steps are the same.

[0049] Comparative Example 4 The difference from Example 1 is that the zircon white glaze step is omitted and the dry particle spraying step is replaced with direct glaze spraying, and the firing temperature is 1200℃.

[0050] Observe the cracking and presence of air bubbles in the glossy countertops obtained in Examples 1-3 and Comparative Examples 1-4. Cracking conditions include obvious cracking, minor cracking, and no cracking. Water absorption and thermal stability tests were also conducted. Water absorption was tested according to the standard GB / T 3810.3-2016. The thermal stability test procedure included placing the brick blank in an oven, heating it to 150°C and holding it at that temperature for 20 minutes. Then, it was removed and immediately transferred to flowing cooling water at 15°C. This cycle was repeated 3 times. Observe whether the brick body has cracks, fissures, or chipping. The test results are shown in Table 1.

[0051] Table 1 - Test Results

[0052] As shown in Table 1, the water absorption rates of Examples 1-3 and Comparative Examples 1-4 were all 0.01-0.03%, all meeting the double zero water absorption rate (≤0.05%). Comparative Example 1 omitted the zirconium white glaze step, resulting in a lack of glaze protection at the edges after polishing, leading to a significant increase in cracking rate due to moisture penetration. This indicates a causal relationship between zirconium white glaze sealing and reducing edge cracking. Comparative Example 4 omitted both zirconium white glaze and dry particle degassing, and was fired at high temperature, resulting in the highest cracking rate. Comparative Example 2 retained the zirconium white glaze and was fired at a low temperature, resulting in no cracking. Furthermore, Comparative Example 1 had a poorer appearance due to the lack of zirconium white glaze coverage.

[0053] Examples 1-3 showed no bubbles, while Comparative Examples 2 and 4 showed bubbles. Comparative Example 2, which changed the dry granule spraying method to direct glaze spraying, showed bubbles; Comparative Example 4, which also used direct glaze spraying, also showed bubbles. Dry glaze granules effectively eliminate interlayer bubbles.

[0054] Examples 1-3 all passed the thermal stability test, as did Comparative Example 2. However, Comparative Example 1 showed micro-cracks at the edges, while Comparative Examples 3 and 4 showed cracking and edge chipping. Comparative Example 1 omitted the zircon white glaze, resulting in a lack of edge protection and decreased thermal stability. Comparative Examples 3 and 4 were fired at a high temperature of 1200℃, leading to a severe mismatch in thermal expansion between the body and the glaze layer. Even with a high degree of vitrification, these examples could not pass the thermal stability test.

[0055] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
