The invention relates to a method for producing
foam glass mosaic based on
boron sludge and pertains to the technical field of functional inorganic material. The invention is characterized in that the invention comprises the steps: waste glass is crushed, mixed with de-magging
boron sludge according to ratio and grinded into green stock; the green stock is heated, quenched, dried and grinded into glass
powder; certain amount of glass
powder is mixed with vesicant, latent
solvent and foam stabilizer to form
foam glass layer material; certain amount of glass
powder,
pigment and complete fusion are mixed to form mosaic layer material; the mosaic layer material and the
foam glass layer material are put into a die sequentially, pressed and molded and the foam glass mosaic is obtained after heating, foaming, foam stabilizing and annealing. The product of the invention is a
bifunctional compound material, one layer of which is foam glass phase and other layer of which is mosaic phase, thus solving the problem that the foam glass can not be directly used as
building material due to
porosity and uneven color, moreover, the invention can reduce the cost of foam glass mosaic without wastes being discharged during the whole process, has
greening and environment protective functions and pertains to environmental friendly technology.
