Method for preparing aluminum silicate board by recycling environment-friendly aluminum silicate

The invention belongs to the technical field of refractory heat-preservation materials, and provides a method for preparing an aluminum silicate board by recycling environment-friendly aluminum silicate. The method comprises the following steps: mechanically crushing recycled aluminum silicate waste materials and then sending the crushed waste aluminum silicate waste materials to an aluminum silicate solution tank, adding water and uniformly carrying out stirring to obtain an aluminum silicate solution; sending the aluminum silicate solution to a stirring tank, adding a modified adhesive, carrying out stirring to obtain slurry, feeding the slurry into a forming tank, putting a forming mold into the forming tank, carrying out vacuumizing, so that a slurry material in the slurry is drawn into the mold and the residual liquid is drawn into a vacuum tank under a vacuum effect, then pumping the residue liquid into a high-level water tank from the vacuum tank through a water pump, depositingand forming the slurry m
