Abstract

The invention discloses a preparation method of low-temperature composite foam glass and belongs to the technical field of foam glass preparation. The preparation method comprises adding boric acid into a sodium silicate solution, carrying out uniform mixing to obtain high-viscosity liquid sol in the premise of no gelling, then adding a vegetable oil emulsion into a solution, carrying out uniformstirring, adding fermented broth obtained by fresh grape skin fermentation into the solution, adding the fermented broth into the liquid sol, drying the composite liquid sol to obtain composite solidsol, adding limestone as a foaming agent into the sol, adding borax as a cosolvent into the sol, uniformly mixing the sol, foaming agent and borax to obtain mixed sol, designing unit weight of 260-270kg / m<3>, putting the fine composite solid sol corresponding to the designed unit weight into a mold, sealing the mold, transferring the sealed mold into a heating device, carrying out preheating, carrying out melting heat-preservation foaming in an oven, carrying out cooling to the room temperature and carrying out annealing and demolding to obtain the low-temperature composite foam glass.

Description

technical field [0001] The invention discloses a method for preparing low-temperature composite foam glass, which belongs to the technical field of foam glass preparation. Background technique [0002] Foam glass is a kind of waste flat glass and bottle glass as raw materials, adding foaming agent, modified additive and foaming accelerator, etc., after finely pulverizing and uniformly mixing, then melting at high temperature, foaming and annealing. Inorganic non-metallic glass materials. It is composed of a large number of uniform bubble structures with a diameter of 1 to 2 mm. Among them, the sound-absorbing foam glass is more than 50% open-cell bubbles, and the heat-insulating foam glass is more than 75% closed-cell bubbles. The product density is 160-220 kg / m3, which can be adjusted by changing the production technical parameters according to the requirements of use. . [0003] Foam glass is a light-weight and high-strength building material and decoration material wit...
