Abstract

The invention relates to a high-strength inorganic foaming fireproof insulation wall material produced through attapulgite and a manufacturing process thereof. According to the technical scheme, the attapulgite, red clay and limestone are made into micro fine powder and mixed evenly in proportion; fine powder mixed materials are evenly laid in a baking mold, a high-strength fireproof steel net is fixedly arranged in the mold and arranged among the fine powder mixed materials, and the mixed materials and the fireproof steel net are integrally baked, cooled and formed at a time in a high-temperature baking kiln. The high-strength microcrystalline foaming fireproof insulation board produced through the attapulgite and the manufacturing process have the advantages that the overall supporting structural strength of a board can be adjusted and enhanced through the strength of the steel net arranged in the board, so the board has a larger application space in a project, and the safety of building boards in the using process is improved, and the service life of the building boards in the using process is prolonged.

Description

technical field [0001] The invention relates to the field of building engineering materials, in particular to a high-strength microcrystalline foamed fireproof and heat-preserving board produced by using attapulgite and a production process thereof. Background technique [0002] Microcrystalline foam fireproof insulation board is a kind of high-content inorganic silicate mineral material as the main raw material, which has high fireproof insulation performance, low thermal conductivity, new light weight, stable chemical performance, non-toxic and tasteless, and good anti-corrosion and moisture-proof performance. , sound insulation and noise reduction, high waterproof and hydrophobic performance, strong weather resistance and other characteristics of the board material. As a building material, it has great use value and scope of use. [0003] Attapulgite is a crystalline hydrated magnesium aluminum silicate non-metallic clay ore with a fibrous porous structure. Attapulgite i...
