Embodiment Construction

[0016] A refractory ceramic brick made of the following raw materials in weight (kg): 55 pebbles, 15 cullets, 20 apatite, 25 bauxite, 12 bauxite, 18 perlite, 13 serpentine, bleach Pearl 4, dickite 14, asbestos powder 8, mica powder 6, nano aluminum hydroxide 12, nano zirconia 5, modified clay 18;

[0017] The preparation method of described modified clay is as follows: a, take attapulgite, diatomaceous earth, bentonite by mass ratio 6:4:2, mix uniformly, add appropriate amount of water to make the clay slurry that concentration is 40%, then Use 25% sulfuric acid solution to adjust the pH of the slurry to 3, heat in a water bath to 85°C, stir for 4 hours, filter, wash with distilled water until neutral, dry, calcinate at 480°C for 2 hours, pulverize, and pass through a 200-mesh sieve; b. The weight ratio of 1:2 is to mix the above-mentioned treated clay with a concentration of 3mol / L titanium tetrachloride aqueous solution, and then add jade powder equivalent to 3% of t...

Abstract

The invention discloses a refractory ceramic tile and a preparation method thereof. The refractory ceramic tile is prepared from the following raw materials in parts by weight: 50-60 parts of cobblestone, 10-20 parts of cullet, 15-25 parts of apatite, 20-30 parts of bauxite, 10-15 parts of datolite, 16-22 parts of perlite, 9-16 parts of serpentine, 3-6 parts of floating bead, 12-18 parts of dickite, 5-10 parts of asbestos powder, 4-8 parts of mica powder, 10-15 parts of nanometer aluminum hydroxide, 4-6 parts of nanometer zirconia and 15-20 parts of modified clay. The ceramic tile has excellent high temperature resistance, has the refractoriness of over 1200 DEG C, is high in strength, low in shrinkage rate and wide in market prospect, has acid and alkali corrosion resistance and ageing resistance and can be applied to special occasions at relatively high temperature.

Description

technical field [0001] The invention relates to a refractory 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 refractoriness, and are prone to shedding when the temperature exceeds 1000°C, so they cannot be used in special occasions with high temperatures. Contents of the invention [0003] The object of the present invention is to provide a refractory ceramic brick and a preparation met...
