Embodiment Construction

[0016] An antibacterial and mildew-proof ceramic tile, made of the following raw materials in weight (kg): 45 quartz sand, 25 fluorite, 20 gravel chips, 15 illite, 24 loess, 18 mullite, 12 kiln slag, 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 described modified clay is as follows: a, take attapulgite, diatomaceous earth, bentonite by mass ratio 4:3:2, mix uniformly, add appropriate amount of water to make the clay slurry that concentration is 35%, then Use sulfuric acid solution with a concentration of 15% to adjust the pH of the slurry to 4, heat to 95°C in a water bath, stir for 2 hours, filter, wash with distilled water until neutral, dry, calcinate at 450°C for 3 hours, pulverize, and pass through a 250-mesh sieve; b. The weight ratio is 1:2.5. Take the above-mentioned treated clay and mix it with a concentration of 2mol / L titanium tetrachloride aqueous sol...

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 mildew-proof ceramic brick and a preparation method thereof, belonging to the field of building ceramic materials. Background technique [0002] Ceramic bricks are plate or block ceramic products produced by clay, quartz sand and other inorganic non-metallic raw materials through batching, ball milling, powder making, molding, sintering and other processes. They are widely used in decoration and protection of walls of buildings and structures. face and ground. With the rapid development of the real estate industry, the production and consumption of ceramic tiles have achieved greater development. At the same time, the performance requirements of ceramic tiles are also getting higher and higher. It is easy to breed mold when used, which not only affects the appearance of ceramic tiles, but also affects the performance of ceramic tiles. Contents of the invention [0003] The object of the present in...
