Description

Aluminum-based aluminum-plastic waterproof gypsum board based on boric sludge as carrier and preparation method thereof
Technical Field
The invention belongs to the field of gypsum boards, and particularly relates to an aluminum-based aluminum-plastic waterproof gypsum board based on waste boron mud.
Background
The gypsum board is a material prepared by taking building gypsum as a main raw material. The building material has the advantages of light weight, high strength, small thickness, convenient processing, sound insulation, heat insulation, fire prevention and other good performances, and is one of the currently-developed novel light boards. Gypsum boards have been widely used for interior partition walls, wall covering panels, ceilings, sound absorbing panels, floor base boards, and various decorative boards of various buildings such as houses, office buildings, shops, hotels, and industrial plants, and are used indoors, which are not suitable for being installed in bathrooms or kitchens.
The boric sludge is waste residue generated in the production of boric acid, borax and other products, is offwhite and yellowish white powdery solid, is alkaline, contains boron oxide, magnesium oxide and other components, and is commonly called as boric sludge. The stockpiling and disposal of the boric sludge not only occupies a large amount of land, but also can alkalize soil near a storage yard and cause migration and transformation of boron, thereby causing environmental pollution. The main chemical compositions of the boric sludge are MgO and SiO2And contains a certain amount of Fe2O3、B2O3And small amounts of CaO and Al2O3And the like. Boron is present in trace amounts in other minerals and does not form an independent boron-containing mineral. The main mineral compositions of the boron mud after high-temperature calcination are olivine, periclase and a small amount of magnesium ferrite. Therefore, if the waste boron mud can be utilized, not only is the waste utilized, but also the energy is solved, and the urban environment is protected.
