Abstract

The present invention relates to a high-strength inorganic foaming fireproof thermal-insulation wall material produced by using aeolian sand, and a production process thereof. The technical scheme comprises: preparing aeolian sand, red clay and limestone into fine powder, uniformly mixing according to a certain ratio, uniformly spreading the fine powder mixed material into a firing mold, loading the mold into a high-strength fireproof steel mesh in an inner-fixation manner, arranging in the middle of the fine powder mixed material, and carrying out high temperature kiln firing to achieve the integrated firing cooling molding of the mixed material and the fireproof steel mesh in one time. The beneficial effects comprise that: the whole support construction strength of the plate can be adjusted and enhanced through the strength of the steel mesh arranged in the middle of the plate, such that the plate can provide the large application space in the project while the safety and the service life of the building plate in the use process can be increased.

Description

technical field [0001] The invention relates to the field of building engineering materials, in particular to a high-strength inorganic foaming fire-proof and heat-retaining wall material produced by utilizing aeolian sand and a production process thereof. Background technique [0002] The main component of aeolian sand is silica, which is a building material that can be smelted. After research and practice, using aeolian sand can not only produce artificial microcrystalline boards, but also can be mixed with other auxiliary materials to produce foamed boards with high compressive strength, no slag falling, no fragility, and excellent fireproof and thermal insulation properties. It is of great economic value in the construction of building walls. [0003] The currently produced microcrystalline foam fireproof and thermal insulation panels can be used in the construction of exterior walls of multi-storey buildings and small high-rise buildings according to the compressive ...
