Description

Technical Field

[0001] The invention relates to the technical field of ceramic tiles, and in particular to a highly wear-resistant and antibacterial ceramic tile and a preparation method thereof. Background Art

[0002] Wear-resistant and antibacterial tiles are tiles with excellent wear resistance and antibacterial properties. They are suitable for places that require high durability and good hygiene. This type of tile is designed through raw material formula and preparation process, and is made of wear-resistant materials. It can withstand the wear and tear in daily use. Adding ingredients with antibacterial properties to the glaze layer or raw materials of the tiles can inhibit the growth of bacteria and provide continuous antibacterial protection.

[0003] However, the existing wear-resistant and antibacterial ceramic tiles still have the problem of insufficient wear resistance due to unreasonable raw material selection and ratio, and the antibacterial effect is reduced due to improper application during the addition of antibacterial agents. At the same time, in order to pursue wear resistance and antibacterial properties, other important properties (such as anti-slip properties, water absorption rate, environmental protection, etc.) will also be unbalanced, and a good balance cannot be achieved. Therefore, the present invention provides a high wear-resistant and antibacterial ceramic tile and a preparation method thereof to solve the above problems. Summary of the invention

[0004] In view of the deficiencies in the prior art, the object of the present invention is to provide a highly wear-resistant and antibacterial tile and a preparation method thereof.

[0005] A highly wear-resistant and antibacterial ceramic tile, comprising the following raw materials in parts by weight: 35-45 parts of kaolin, 15-25 parts of quartz sand, 10-20 parts of feldspar powder, 8-12 parts of waste and broken ceramic powder, 3-7 parts of wollastonite, 2-4 parts of alumina and 5-8 parts of antibacterial glaze; The antibacterial glaze comprises, by weight, 1-3 parts of nano zinc oxide, 1-3 parts of nano silver ion solution, 4-6 parts of water-based acrylic emulsion and 2-4 parts of sodium silicate.

[0006] Preferably, the particle size of the waste ceramic powder is 50-300 μm.

[0007] Preferably, the concentration of the nano silver ion solution is 5-10 mg / L.

[0008] Preferably, the antibacterial glaze further comprises 0.5-1 part of nano titanium dioxide as a photocatalytic aid.

[0009] Kaolin has high hardness and toughness, which can improve the mechanical strength and compressive resistance of tiles, making them harder and more durable. Secondly, the stability and excellent chemical properties of kaolin can improve the wear resistance and chemical corrosion resistance of tiles. In addition, kaolin, as a filler and coagulant, can promote the crystal growth of tiles, making them more uniform and transparent, reducing the generation of bubbles and defects, and improving the quality and color of tiles. The high hardness of quartz sand can improve the hardness and wear resistance of tiles, making them more durable. At the same time, its low thermal expansion coefficient helps to improve the thermal stability of tiles. Feldspar powder contains rich alkali metal oxides, which can improve the fire resistance and acid and alkali resistance of tiles, making them less susceptible to corrosion. In the process of firing tiles, feldspar powder can be used as a flux to promote the melting and sintering of tiles. Using waste ceramic powder as part of the raw material can reduce production costs. Waste ceramic powder contains a certain amount of aluminum oxide and other oxides, which help to improve the hardness and wear resistance of tiles; Wollastonite has good mechanical properties and thermal stability, and can enhance the strength and hardness of tiles. Adding wollastonite to the raw materials can adjust the glossiness and hardness of tiles, making them more beautiful and durable. The high hardness of alumina is used to improve the hardness and wear resistance of tiles. At the same time, the addition of alumina can also improve the color and gloss of tiles. These raw materials work synergistically in the production of highly wear-resistant and antibacterial tiles, comprehensively improving the performance of the tiles. The respective advantages of kaolin, quartz sand, feldspar powder, wollastonite, alumina and other raw materials are superimposed and enhanced after mixing, jointly improving the mechanical strength, wear resistance, fire resistance, acid and alkali resistance, brightness, thermal stability and aesthetics of the tiles. Waste and broken ceramic powder can reduce the use of high-cost raw materials while ensuring the performance of the tiles, thereby reducing costs.

[0010] In antibacterial glazes, nano zinc oxide is used as the antibacterial ingredient, and nano silver ion solution is added to enhance the antibacterial effect, water-based acrylic emulsion is used to improve the adhesion of the glaze, and sodium silicate is used to enhance the glaze strength.

[0011] A method for preparing highly wear-resistant antibacterial ceramic tiles comprises the following steps: (1) Mixed ball milling: kaolin, quartz sand, feldspar powder, waste ceramic powder, wollastonite and alumina are mixed evenly in proportion, ground to 80-200 mesh by a ball mill, 5-20% of water is added to the total amount of raw materials, and stirred to form a plastic mud; (2) Body forming: The clay is pressed into a ceramic tile body by a mold at 20-50 MPa, and necessary finishing is performed; the formed body is placed in a drying room for natural drying or forced drying, and the residual moisture content is controlled to be 2-4%. The dried body is corrected to ensure a smooth surface without defects; (3) Glazing and drying: Mix nano zinc oxide, nano silver ion solution, water-based acrylic emulsion and sodium silicate in proportion, add 1.5-2 times the total mass of water, stir and disperse evenly to form an antibacterial glaze; apply the antibacterial glaze evenly on the surface of the tile body to form a glaze layer; place the glazed tiles in a drying room and dry them at 60-100°C for 1-5 hours to solidify the glaze layer; (4) High-temperature sintering: The dried ceramic tile body is placed in a high-temperature kiln for sintering. The sintering temperature is 1200-1250°C and the insulation time is 1-2 hours. During the sintering process, the glaze layer is tightly combined with the body to form a strong, wear-resistant and antibacterial ceramic tile surface. (5) Post-processing: After sintering, the tiles are cleaned and polished to obtain highly wear-resistant and antibacterial tiles.

[0012] Preferably, in the (1) mixing and ball milling, 0.1-0.5 parts by mass of a dispersant is added during the mixing and ball milling process.

[0013] Preferably, in the (2) green body forming, the forced drying adopts a hot air circulation drying method, and the drying temperature is controlled not to exceed 80°C.

[0014] Preferably, during the (3) glazing and drying, the antibacterial glaze is evenly sprayed on the surface of the tile body by using a glazing spraying technique.

[0015] Preferably, during the (4) high temperature sintering, a nitrogen protective atmosphere is introduced into the sintering process.

[0016] Preferably, the post-treatment (5) further comprises anti-fouling treatment of the ceramic tiles, that is, after polishing, the ceramic tiles are immersed in a solution containing an anti-fouling agent.

[0017] After the clay is formed into a body, it is dried and a certain degree of roughness and porosity is formed on the surface of the body, which is conducive to the penetration and adhesion of the glaze. After glazing, the glaze can better penetrate into the surface of the body and tightly combine with the body. The glaze layer solidifies synchronously with the body during the sintering process. The antibacterial components in the glaze layer can be evenly distributed in the glaze layer to form a solid glaze protective layer. This combination method is more solid than directly glazing on the smooth surface after sintering, and reduces the risk of glaze falling off.

[0018] The beneficial effects achieved by the present invention are as follows: 1. The present invention can improve the hardness and wear resistance of ceramic tiles by selecting highly wear-resistant and hard raw materials and by reasonably matching the raw materials. Antibacterial glaze is prepared using antibacterial components, acrylic emulsion and sodium silicate. During the preparation process, a green body is formed by pressing mud materials, and glazing is performed after drying so that the antibacterial glaze is evenly and firmly attached to the green body. After drying and curing, sintering is performed so that the glaze layer is closely combined with the green body to form a strong, wear-resistant and antibacterial ceramic tile surface, while taking into account other properties such as anti-slip properties, water absorption rate and environmental protection.

[0019] 2. The present invention selects highly wear-resistant raw materials such as kaolin and quartz sand as matrix materials to ensure the firmness and stability of the basic structure of the tile, introduces hard phase materials such as alumina as reinforcing agents to make the internal structure of the tile denser and harder, and utilizes the unique particle morphology and hardness characteristics of waste broken ceramic powder to further enhance the bonding force between particles, thereby further improving the hardness and wear resistance of the tile.

[0020] 3. The present invention utilizes acrylic emulsion as an additive for antibacterial glaze, which can improve the bonding strength between ceramic tiles and glaze layers, and at the same time utilizes the waterproofness and weather resistance of acrylic acid to effectively resist the erosion of ceramic tiles by the external environment.

[0021] 4. The present invention combines the use of sodium silicate to further enhance the chemical stability of the ceramic tile. As an inorganic adhesive and hardener, sodium silicate can form a dense protective film on the surface of the ceramic tile, effectively isolating the penetration of harmful substances such as moisture, acid and alkali, preventing the ceramic tile from being damaged by corrosion, and at the same time improving the stain resistance and easy cleaning of the ceramic tile.
