Abstract

A thermally insulating brick used for high-temperature furnaces is disclosed. The thermally insulating brick is prepared from following raw materials by weight: 35-45 parts of dry-mixed mortar, 15-25 parts of rock wool, 10-25 parts of rubber powder polyphenyl granules, 25-30 parts of saw dust powder, 5-10 parts of kaolin and 40-50 parts of water. The thermally insulating brick is scientific in formula, and has advantages of high strength, low heat conductivity, capability of being economical and practical, and the like.

Description

technical field [0001] The invention relates to a building material, in particular to a thermal insulation brick. Background technique [0002] At present, with the progress of my country's metallurgical industry, it has become urgent to develop high-efficiency high-temperature furnaces, which puts forward higher requirements for the construction of high-temperature furnace insulation bricks. In recent years, in order to enhance the thermal insulation effect of bricks, more expensive raw materials have been added to the production of thermal insulation bricks, which has increased production costs; or due to insufficient raw materials, the thermal insulation effect of the produced thermal insulation bricks is not ideal. Contents of the invention [0003] The object of the present invention is to provide an economical and practical thermal insulation brick with good thermal insulation effect. [0004] In order to achieve the above object, the present invention is achieved t...
