Abstract

The invention discloses a fired clay hollow brick with low thermal conductivity and a preparation method thereof. The brick is prepared from the following raw materials (by weight): 23-35 parts of yellow phosphorus slag, 18-27 parts of arsenic sandstone area, 20-25 parts of vermiculite, 9-14 parts of yellow dextrin, 10-15 parts of nanoporous silica aerogel, 22-28 parts of oyster shell, 5-10 parts of hydroxyethyl cellulose, 14-22 parts of sepiolite, 8-12 parts of sawdust, 7-13 parts of zirconia and a proper amount of water. The fired clay hollow brick prepared from raw materials including coal cinder, sawdust, nanoporous silica aerogel, cement dust and the like has characteristics of low heat conductivity coefficient, high strength, corrosion resistance, ageing resistance and good seismic stability.

Description

technical field [0001] The invention relates to a hollow brick and a preparation method thereof, in particular to a low thermal conductivity 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 fi...
