Problems solved by technology

The ceramic tiles currently on the market have poor corrosion resistance. After contact with corrosive substances such as acid, alkali, salt, etc., the surface layer is easily corroded, resulting in the loss of luster on the surface of the tiles, forming a rough and dull corrosion surface, which affects the appearance.

Embodiment Construction

[0016] A corrosion-resistant ceramic brick made from the following raw materials by weight (kg): barite 42, limestone 33, vermiculite 21, weathered sand 18, calcined clay 16, waste mortar 8, spinel 15, gold mine tailings Slag 12, opal 16, slaked lime 11, nano boron nitride 12, calcium silicate 6, modified clay 30, sodium carbonate 3;

[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 30%, then Use a sulfuric acid solution with a concentration of 15-25% to adjust the pH of the slurry to 4, heat it in a water bath to 90°C, stir for 3 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 1. Take the above-mentioned treated clay with a concentration of 2.5mol / L titanium tetrachloride aqueous solution an...

Abstract

The invention discloses a corrosion-resistant ceramic tile and a preparation method thereof. The corrosion-resistant ceramic tile is prepared from the following raw materials by weight: 36-48 parts of barite, 27-39 parts of limestone, 15-25 parts of vermiculite, 12-24 parts of weathered sand, 14-20 parts of calcined potter clay, 5-10 parts of waste mortar, 10-20 parts of spinel, 8-16 parts of gold ore tailings, 11-23 parts of opal, 6-13 parts of slaked lime, 9-18 parts of nanometer boron nitride, 4-8 parts of calcium silicate, 22-34 parts of modified clay, and 2-4 parts of sodium carbonate. The ceramic tile of the invention has excellent chemical corrosion resistance, can resist long-term and repeated erosion caused by household chemical reagents, chemical articles, and acid-base salts such as swimming pool salts and the like, has maintained surface gloss, is high in strength, low in water absorption and good in weatherability, has greatly increased service life, is widely applicable to walls and floors of living rooms, bathrooms, kitchens, balconies, and the like, and has wide market prospects.

Description

technical field [0001] The invention relates to a corrosion-resistant 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. The ceramic tiles currently on the market have poor corrosion resistance. After contact with corrosive substances such as acid, alkali, salt, etc., the surface layer is easily corroded, resulting in the loss of luster on the surface of the tiles, forming a rough and dull corrosion surface, which affects the appearance. Cont...
