Abstract

The invention discloses a fireproof fired clay hollow brick and a preparation method thereof. The fireproof fired clay hollow brick is prepared from the following raw materials (by weight): 15-25 parts of Benshan green mud, 17-29 parts of picrite, 7-14 parts of high aluminum fine powder, 9-18 parts of fused magnesite, 13-21 parts of periclase, 10-15 parts of high boron calcium borate, 16-24 parts of petroleum coke slag, 11-19 parts of kyanite ore tailings, 5-10 parts of sodium metaantimonate, 18-26 parts of brown fused alumina slag, 14-22 parts of silica fume, 32-46 parts of attapulgite, 17-23 parts of polyvinyl alcohol, 8-14 parts of magnesium silicate, 12-18 parts of barite, 10-15 parts of chromite slag, 13-21 parts of sawdust, 19-33 parts of fly ash and a proper amount of water. The prepared fired clay hollow brick has both excellent flame retardancy and fire resistance, long-term operation temperature of the fired clay hollow brick is also greatly raised. Actual operation temperature can reach 1350 DEG C and above.

Description

technical field [0001] The invention relates to a hollow brick and a preparation method thereof, in particular to a refractory sintered clay hollow brick and a preparation method thereof. Background technique [0002] Hollow brick is the main wall material commonly used in the construction industry. Due to its advantages of light weight and low consumption of raw materials, it has become the first product recommended by the national construction department. Sintered clay hollow bricks are made of clay and mineral raw materials as the main raw materials, which are processed, shaped and sintered. Sintered clay hollow brick has the advantages of light weight, high strength, good thermal insulation, sound insulation and noise reduction performance, environmental protection and no pollution, etc. It is an ideal filling material for frame structure buildings. In recent years, with the rapid development of the construction industry, the performance requirements of fired clay hollo...
