Embodiment Construction

[0016] An anti-bacterial and anti-mildew ceramic tile made of the following weight (kg) raw materials: quartz sand 45, fluorite 25, crushed stone chips 20, illite 15, loess 24, mullite 18, furnace slag 12, chalk Powder 8, modified clay 28, bone meal 10, zinc silicate 3, copper oxide 2, silver-loaded zirconium phosphate 5;

[0017] The preparation method of the modified clay is as follows: a. Weigh attapulgite, diatomaceous earth, and bentonite according to a mass ratio of 4:3:2, mix them evenly, add an appropriate amount of water to make a 35% clay slurry, and then Adjust the slurry PH to 4 with 15% sulfuric acid solution, heat to 95℃ in a water bath, stir for 2h, filter, wash with distilled water to neutrality, dry, calcinate at 450℃ for 3h, crush, and pass through a 250 mesh sieve; b. The weight ratio is 1:2.5. Take the above-treated clay and the concentration of 2mol / L titanium tetrachloride aqueous solution and mix uniformly, and then add 2.5% of the total weight of the mixtu...

Abstract

The invention discloses an antimicrobial mildew-proof ceramic tile and a preparation method thereof. The ceramic tile is prepared from the following raw materials in parts by weight: 40-50 parts of quartz sand, 20-30 parts of fluorite, 15-25 parts of gravel dust, 10-20 parts of illite, 16-28 parts of loess, 14-22 parts of mullite, 8-16 parts of furnace slag, 4-12 parts of a chalk powder, 24-32 parts of modified clay, 5-15 parts of bone meal, 2-4 parts of zinc silicate, 1-3 parts of copper oxide, and 3-8 parts of silver-loaded zirconium phosphate. Zinc silicate, copper oxide, silver-loaded zirconium phosphate and other inorganic antibacterial agents are added into the ceramic tile, and besides, the modified clay also has the sterilization efficacy, so that the ceramic tile has quite good antibacterial mildew-proof properties, has the sterilizing rate reaching 90% or more, and can effectively inhibit propagation of mildew; and the prepared ceramic tile has the characteristics of being high in strength, low in water absorption rate, good in abrasion resistance, good in weather resistance and durable in use.

Description

Technical field [0001] The invention relates to an antibacterial and mold proof ceramic tile and a preparation method thereof, and belongs to the field of building ceramic materials. Background technique [0002] Ceramic tiles are plate-shaped or block-shaped ceramic products produced from clay, quartz sand and other inorganic non-metallic materials through batching, ball milling, powdering, molding, sintering and other processes. They are widely used to decorate and protect the walls of buildings and structures. Surface and ground. With the rapid development of the real estate industry, the production and consumption of ceramic tiles have been greatly developed. At the same time, the performance requirements of ceramic tiles are also getting higher and higher. However, the current ceramic tiles on the market have poor antibacterial and mildew resistance. Use is easy to breed mold, which not only affects the appearance of ceramic tiles, but also affects the performance of cerami...
