Description

Technical Field

[0001] The invention belongs to the technical field of ceramic tiles, and in particular relates to a ceramic tile with a metal wire drawing effect and a preparation method thereof. Background Art

[0002] As a common building decoration material, ceramic tiles are widely used in various buildings and indoor and outdoor decorations due to their beautiful appearance, durability and easy cleaning. However, traditional ceramic tiles have certain limitations in terms of corrosion resistance and decorative effect, which restricts their application in certain special environments. In existing technologies, the corrosion resistance of ceramic tiles mainly depends on the chemical composition and structure of their glaze.

[0003] However, traditional glaze formulas often cannot meet the requirements of environments with high corrosion resistance, such as kitchens, bathrooms, laboratories, etc. In these environments, tiles are easily affected by acid and alkali erosion, wear and water vapor, resulting in surface damage, thereby reducing their aesthetics and service life. At the same time, traditional tile decoration methods, such as printing and glaze spraying, can provide certain visual effects, but cannot achieve metallic texture and dynamic light and shadow effects, which limits the competitiveness of tiles in the high-end decoration market.

[0044] In a preferred embodiment, in step S1, the corrosion resistant agent component is:

[0045] Zirconium oxide (ZrO2): 25wt%

[0046] Alumina (Al2O3): 20wt%

[0054] Calcium silicate CaSiO3: 5wt%

[0055] Organic silane coupling agent: 2wt%

[0056] Nano-silicon dioxide (SiO2 nanoparticles): 5wt%;

[0057] The preparation method of the corrosion resistant agent is as follows: First, various inorganic powder components such as zirconium oxide, aluminum oxide, magnesium silicate, rare earth element oxides, titanium oxide, chromium oxide, cobalt oxide, nickel oxide and silicate fillers are accurately weighed according to the formula ratio and placed in a high-speed mixer for pre-mixing. Subsequently, nano-silicon dioxide is added to enhance the wear resistance and adhesion of the coating. Next, an organic silane coupling agent is gradually added during the mixing process to promote the chemical bonding of the filler to the surface of the tile. After the mixing is completed, the mixture is finely ground to ensure that all ingredients are evenly dispersed at the nanometer level. Finally, a high-pressure homogenizer is used for homogenization to obtain a stable suspension or paste-like corrosion resistant agent, which can be used for the surface treatment of tiles.

[0058] In a preferred embodiment, in step S2, when mixing the raw materials in the ball mill, the speed of the ball mill is controlled at 60-80 revolutions per minute, and zirconium oxide balls are used as grinding media with a size in the range of 0.5-1.0 mm. During the ball milling process, the ratio of raw materials to water is controlled at 1:1.5 to 1:2.0 to maintain proper fluidity of the slurry. The ball milling time is at least 24 hours, during which the fineness and uniformity of the slurry are regularly checked, and sieving is performed to remove oversized particles if necessary;

[0059] In step S3, the operating parameters of the spray drying tower include controlling the inlet temperature at 200-250°C and the outlet temperature at 100-150°C. The speed of the atomizer is adjusted according to the viscosity of the slurry to obtain uniform droplets. The moisture content of the dried powdered material is controlled within 6% to 8% to ensure suitable plasticity during pressing.

[0060] In a preferred embodiment, in step S4, the pressing of the tile blank is carried out on a hydraulic press, the pressure is controlled at 200-300 tons, and the pressure is maintained for about 30-60 seconds to ensure the density and dimensional stability of the blank. The thickness of the blank after pressing is controlled at 6-10 mm;

[0061] In step S5, the drying process is carried out in a tunnel dryer, the temperature is controlled at 100-120° C., the relative humidity is controlled at 55%-65%, and the drying time is about 6-8 hours, so that the moisture content of the green body is reduced to 2%-4%.

[0062] In a preferred embodiment, in step S6, when preparing the glaze, a high-speed stirrer is used with a rotation speed of 1000-1500 rpm to ensure that the organosilane water repellent, the silane coupling agent and the nano-silicon dioxide can be evenly dispersed in the base glaze. The stirring time is at least 1 hour, and the uniformity of the glaze is regularly checked during the stirring time.

[0063] In a preferred embodiment, in step S7, when applying the glaze, an automatic glazing machine is used, and the thickness of the glaze layer is controlled to be 0.5-1.0 mm. During the glazing process, the ceramic tile blank is kept moving smoothly to avoid glaze accumulation or dripping.

[0064] In a preferred embodiment, in step S8, during the firing process, the heating rate of the kiln is controlled at 5-10°C / min, and the firing temperature is maintained for 1-2 hours after reaching the firing temperature. Accurate control of the firing temperature is crucial to ensure the strength and glaze quality of the tiles.

[0065] In a preferred embodiment, in step S9, the cooling process is performed slowly to avoid thermal cracking of the tiles. The rate of natural cooling or forced cooling is controlled at 20-30°C / hour until the temperature of the tiles drops below 100°C.

[0066] In a preferred embodiment, in step S10, during the metal wire drawing process, the wire drawing equipment has a line speed of 10-15 meters per minute, and the strength is adjusted according to the hardness of the tile surface to form a uniform metal wire drawing texture. The wire drawing direction and texture depth are adjusted according to design requirements;

[0067] In step S11, during the inspection process, the appearance, size and flatness of the tiles are inspected using precision measuring tools and instruments. The appearance inspection is carried out under good lighting conditions, and the size error is controlled within ±1 mm, and the flatness error is less than 0.5 mm. Qualified products are packaged in foam packaging and cartons to ensure safety during transportation.

[0068] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0069] 1. In the present invention, zirconium oxide, aluminum oxide and other ingredients in the corrosion resistance agent can improve the resistance of the ceramic tile surface to chemical substances such as acids and alkalis, so that the ceramic tile is not easily corroded or damaged when it comes into contact with chemicals such as kitchen condiments and detergents. The addition of nano-silicon dioxide and silicate fillers improves the hardness and wear resistance of the ceramic tile surface, making the ceramic tile more durable and less prone to scratches in daily use. Ingredients such as rare earth element oxides can improve the physical properties of ceramic tiles, increase their strength and toughness, and thus increase the overall service life of the ceramic tile. By enhancing the corrosion resistance, ceramic tiles are suitable for more environments, such as commercial kitchens, laboratories, hospitals and other places that have high requirements for material corrosion resistance. Ceramics with excellent corrosion resistance can meet higher standards, enhance the market competitiveness of products, and attract more consumers.

[0070] 2. In the present invention, the metal brushed effect provides a unique metallic luster and texture for the surface of the tile, enhances the aesthetics and design of the product, and meets the consumer's demand for personalized and high-end decorative materials. The metal brushed texture can reflect light, so that the surface of the tile produces a dynamic light and shadow effect, which enhances the decorative effect and layering of the space. As a special process, metal brushing can significantly increase the added value of tiles and bring higher economic benefits to manufacturers. The metal brushed texture can cover up minor flaws on the surface of the tile to a certain extent, making the product look more perfect as a whole. Through different brushing speeds, strengths and directions, a variety of metal brushed effects can be created, providing the market with a variety of product choices. DETAILED DESCRIPTION

The thickness of the blank after pressing should be controlled at 6-10 mm;

[0196] In step S5, the drying process should be carried out in a tunnel dryer, with the temperature controlled at 100-120°C, the relative humidity controlled at 55%-65%, and the drying time being about 6-8 hours, so as to reduce the moisture content of the green body to 2%-4%.

[0197] In step S6, when preparing the glaze, a high-speed stirrer is used, and the rotation speed should reach 1000-1500 rpm to ensure that the organosilane water repellent, silane coupling agent and nano-silicon dioxide can be evenly dispersed in the base glaze. The stirring time is at least 1 hour, and the uniformity of the glaze is regularly checked during this period.

[0198] In step S7, when applying the glaze, an automatic glazing machine is used, and the thickness of the glaze layer is controlled to be 0.5-1.0 mm. During the glazing process, the ceramic tile blank should be kept moving smoothly to avoid glaze accumulation or dripping.

[0199] In step S8, during the firing process, the heating rate of the kiln should be controlled at 5-10°C / minute, and the firing temperature should be maintained for 1-2 hours after reaching the firing temperature. Accurate control of the firing temperature is crucial to ensure the strength and glaze quality of the tiles.

[0200] In step S9, the cooling process should be carried out slowly to avoid cracking of the tiles caused by thermal stress. The rate of natural cooling or forced cooling should be controlled at 20-30°C / hour until the temperature of the tiles drops below 100°C.

[0201] In step S10, during the metal wire drawing process, the wire drawing equipment's linear speed should be controlled at 10-15 meters per minute, and the strength should be adjusted according to the hardness of the tile surface to form a uniform metal wire drawing texture. The wire drawing direction and texture depth should be adjusted according to the design requirements;

[0202] In step S11, during the inspection process, the appearance, size and flatness of the tiles are inspected using precision measuring tools and instruments. The appearance inspection should be carried out under good lighting conditions, the size error should be controlled within ±1 mm, and the flatness error should be less than 0.5 mm. Qualified products are packaged in foam packaging and cartons to ensure safety during transportation.

[0203] In the present invention, zirconium oxide, aluminum oxide and other components in the corrosion resistance agent can improve the resistance of the ceramic tile surface to chemical substances such as acids and alkalis, so that the ceramic tile is not easily corroded or damaged when it comes into contact with chemicals such as kitchen condiments and detergents. The addition of nano-silicon dioxide and silicate fillers improves the hardness and wear resistance of the ceramic tile surface, making the ceramic tile more durable and less prone to scratches in daily use. Ingredients such as rare earth element oxides can improve the physical properties of the ceramic tile, increase its strength and toughness, and thus increase the overall service life of the ceramic tile. By enhancing the corrosion resistance, the ceramic tile is suitable for more environments, such as commercial kitchens, laboratories, hospitals and other places that have high requirements for the corrosion resistance of the material. Ceramic tiles with excellent corrosion resistance can meet higher standards, enhance the market competitiveness of the product, and attract more consumers.

[0204] In the present invention, the metal brushed effect provides a unique metallic luster and texture for the surface of the tile, enhances the aesthetics and design of the product, and meets the consumer's demand for personalized and high-end decorative materials. The metal brushed texture can reflect light, so that the surface of the tile produces a dynamic light and shadow effect, which enhances the decorative effect and layering of the space. As a special process, metal brushing treatment can significantly increase the added value of the tile and bring higher economic benefits to manufacturers. The metal brushed texture can cover up minor flaws on the surface of the tile to a certain extent, making the product look more perfect as a whole. Through different brushing speeds, strengths and directions, a variety of metal brushed effects can be created, providing the market with a variety of product choices.
