Abstract

The invention discloses a method for producing a foam microcrystal glass by utilizing a composite industrial residue, and is characterized by comprising the following steps of: crushing different industrial residues, after mixing proportionally, grinding to raw material powder, heating, melting, quenching and drying the raw material powder, grinding to clinker powder, adding a nucleation agent, a foaming agent, a foam stabilizer, a fluxing agent and an enhancer to form a foam microcrystal batch, after pressing the batch, preheating, foaming, stabilizing the foam and annealing, sintering to obtain the foam microcrystal glass. According to the invention, burnability of the batch is remarkably improved, the burning temperature is reduced, the production cost of the foam microcrystal glass is reduced, and the method has the characteristics of abundant raw material sources, low cost, simple process, environmental friendliness, and the like. The product foam microcrystal glass has the characteristics of excellent performance quality, low volume weight, high intensity, fire protection, water tightness, corrosion resistance, no ageing, no radioactivity and the like, and is an environmental-friendly new material.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a foamed glass-ceramic and a production method thereof, in particular to a method for producing foamed glass-ceramic by using composite industrial waste residues and the prepared foamed glass-ceramic. Background technique [0002] At present, most of the raw materials for the production of foam glass are industrial and daily-use cullet glass powder, and mineral raw materials are also used for secondary processing. After water quenching, they are dried, crushed and ground to replace part of the glass powder, and then roasted at high temperature (1000~1200 ℃) to make foam glass products. The source of raw materials for producing such foam glass products is relatively narrow, the production cost is relatively high, the process is relatively complicated, and the popularization and application are limited, so it can only be used in special industrial thermal insulation projec...
