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-ceramics by using composite industrial waste slag and the prepared foamed glass-ceramics. Background technique [0002] At present, most of the raw materials for the production of foam glass are industrial and daily cullet glass powder, but also useful mineral raw materials after secondary processing, water quenching, drying, crushing, and grinding to replace part of the glass powder, and then high-temperature roasting (1000~1200 ℃ or so) to produce foam glass products. The source of raw materials for the production of this foam glass product is relatively narrow, the production cost is relatively high, the process is relatively complicated, and its promotion and application are restricted, and it can only be used in relatively special industrial insulation projects. ...
