Embodiment Construction
[0016] A heat-insulating ceramic brick with low thermal conductivity, made of the following raw materials in weight (kg): 40 calcite, 25 quartz sand, 24 pumice, 18 pyrophyllite, 20 expanded perlite, 12 vitrified microbeads, 8 steel slag powder, electrical Stone 7, cinder 12, sawdust 6, zirconium silicate 4, zinc borate 3, coke powder 7, modified clay 25;
[0017] The preparation method of described modified clay is as follows: a, weigh attapulgite, diatomaceous earth, bentonite by mass ratio 4:2:1, mix uniformly, add appropriate amount of water to make the clay slurry that concentration is 36%, then Use sulfuric acid solution with a concentration of 25% to adjust the pH of the slurry to 3.5, 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 200-mesh sieve; b. The weight ratio is 1:2, take the above-mentioned treated clay and mix it with a concentration of 2mol / L...

Abstract
The invention discloses a thermal-insulation ceramic tile having low thermal conductivity coefficient and a preparation method thereof. The thermal-insulation ceramic tile is prepared from the following raw materials in parts by weight: 30-50 parts of calcite, 20-30 parts of quartz sand, 16-28 parts of pumice, 12-24 parts of pyrophyllite, 15-25 parts of expanded perlite, 10-15 parts of vitrified small balls, 6-12 parts of a steel slag micro-powder, 5-10 parts of tourmaline, 8-14 parts of coal cinder, 4-9 parts of sawdust, 3-6 parts of zirconium silicate, 2-5 parts of zinc borate, 6-9 parts of a coke powder, and 20-30 parts of modified clay. The prepared ceramic tile has the thermal conductivity coefficient of less than 0.2 W / m.K, has good heat-preservation and thermal-insulation properties, saves energy, has the characteristics of light weight, high strength, aging resistance, ultraviolet resistance and the like, and can be used for decoration of exterior walls of residences, wine shops, hotels, kindergartens, office buildings, factories, workshops, commercial buildings and the like.
Description
technical field [0001] The invention relates to a heat-insulating ceramic brick with low thermal conductivity 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, the ceramic tiles currently on the market have high thermal conductivity and poor thermal insulation effect, so they cannot be used for external wall thermal insulation decoration.
