Abstract

The invention discloses a fire-resistant and heat-preserving ceramsite brick. The fire-resistant and heat-preserving ceramsite brick is prepared from the following raw materials in parts by weight: 2-3 parts of micro powder of silicon carbide (the particle size is 15 [mu]m), 25-30 parts of powder of fluorite ore tailings (the particle size is 100-200 [mu]m), 8 parts of andalusite powder (the particle size is 200-300 [mu]m), 0.5 part of sericite powder (the particle size is 20-28 [mu]m), 2 parts of white mica powder (the particle size is 5 [mu]m), 0.9 part of alpha-Al2O3 nano powder (the particle size is 5-8 nm), 5 parts of cement, 0.5-0.6 part of tartaric acid, 20-22 parts of ordinary ceramsite and 0.8 part of malic acid. The fire-resistant and heat-preserving ceramsite brick provided by the invention is light in weight, high in rigidity, fire-resistant and heat shock resistant, and has a corrosion resistant effect and a quite good market prospect.

Description

technical field [0001] The invention belongs to the technical field of refractory materials, and in particular relates to a ceramsite refractory insulation brick and a preparation process thereof. Background technique [0002] Ceramsite is a kind of artificial particle with ceramic texture. It has various functions such as high comprehensive strength, good fire resistance, and weather resistance. Ceramsite is the best lightweight building material. Ceramsite can solve engineering problems such as weight, fire prevention, heat insulation, and heat preservation. Ceramsite has the advantages of weather resistance, low price, good quality, environmental protection, and easy production. It is widely used in prefabricated wall panels (dry walls), partition walls, light High-quality concrete, roof insulation, concrete prefabricated parts, small lightweight blocks, ceramsite bricks, etc. It can also be used in gardening, flowers, municipal and soilless cultivation and other markets....
