Embodiment Construction

[0016] A high-strength ceramic brick made from the following raw materials by weight (kg): yellow sand 50, barite 40, dolomite 20, volcanic rock 15, zircon 25, mullite 10, blast furnace slag 7, modified clay 24. Sea mud 11, silica powder 15, waste brick powder 12, tricalcium phosphate 6, barium carbonate 5, nano-silicon carbide 3, nano-alumina 4;

[0017] The preparation method of described modified clay is as follows: a, take attapulgite, diatomaceous earth, bentonite by mass ratio 4:3:1, mix uniformly, add appropriate amount of water to make the clay slurry that concentration is 35%, then Adjust the pH of the slurry to 4 with a sulfuric acid solution with a concentration of 20%, heat it in a water bath to 90°C, stir for 3 hours, filter, wash with distilled water until neutral, dry, calcinate at 460°C for 3 hours, pulverize, and pass through a 250-mesh sieve; b. The weight ratio of 1:2 is to mix the above-mentioned treated clay with a concentration of 2mol / L titanium ...

Abstract

The invention discloses a high-strength ceramic brick and a preparation method thereof. The ceramic brick is prepared from the following raw materials in parts by weight: 40-60 parts of yellow sand, 30-50 parts of barite, 15-25 parts of dolomite, 10-20 parts of volcanic rock, 20-30 parts of zirconite, 5-15 parts of mullite, 4-12 parts of blast furnace slag, 16-28 parts of modified clay, 7-14 parts of sea mud, 11-19 parts of a silica micro-powder, 8-16 parts of a waste brick powder, 3-9 parts of tricalcium phosphate, 4-8 parts of barium carbonate, 2-5 parts of nano silicon carbide, and 3-6 parts of nano alumina. The prepared ceramic brick has high strength, has the breaking strength of not less than 1050 N and the rupture modulus of not less than 30 MPa, is anti-knock, anti-cracking and non-friable, and enables the service life to be significantly improved.

Description

technical field [0001] The invention relates to a high-strength 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 been greatly developed, and the performance requirements of ceramic tiles are also getting higher and higher. However, most of the ceramic tiles currently on the market have low strength, are not hard enough, are fragile, and have poor usability, which cannot meet the market demand. Contents of the invention [0003] The object of the present invention is t...
