Embodiment Construction

[0015] A low-temperature-resistant ceramic brick made of the following raw materials in weight (kg): sepiolite 44, flint 26, limestone 18, construction waste 12, mountain sand 14, modified clay 22, alum stone 24, sludge dry powder 6 , kyanite 33, straw powder 8, calcium chloride 4, chromium trioxide 3, lightly burned magnesium powder 12;

[0016] The preparation method of the modified clay is as follows: a. Take bauxite, kaolin and attapulgite in a mass ratio of 7:5:3, mix them uniformly, put them into a hydrochloric acid solution with a concentration of 20%, and heat them in a water bath to 65 ℃, keep warm for 1h, filter, wash with distilled water until neutral, dry, calcine at 520°C for 1h, pulverize, pass through a 200 mesh sieve, and set aside; b. Weigh a certain amount of chitosan and add it to the In the acetic acid solution, stirring and dissolving, it is mixed with the chitosan colloidal solution that the weight percent concentration is 12%, then adds the silver ni...

Abstract

The invention discloses a low-temperature-resistant ceramic tile and a preparation method thereof. The ceramic tile is prepared from the following raw materials in parts by weight: 36-48 parts of sepiolite, 21-33 parts of firestone, 15-20 parts of limestone, 10-15 parts of construction waste, 8-16 parts of hill sand, 18-26 parts of modified clay, 16-28 parts of alunite, 4-8 parts of a sludge dry powder, 24-36 parts of kyanite, 5-10 parts of a straw powder, 3-5 parts of calcium chloride, 2-4 parts of chromic oxide, and 9-17 parts of a caustic-burned magnesia powder. The ceramic tile has good low temperature resistance, can be used for a long time under a low temperature condition of below -5 DEG C, does not generate brittle rupture, and has the advantages of high strength, good water resistance, strong anti-erosion ability, good weather resistance, and long service life.

Description

technical field [0001] The invention relates to a low-temperature 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. At present, ceramic tiles on the market have poor low temperature resistance, and are prone to brittle cracks in severe cold weather in winter, which seriously affects the service life of tiles. Contents of the invention [0003] The object of the present invention is to address the deficiencies of the prior art, an...
