Abstract

The invention discloses a method for preparing foam glass by utilizing waste glass and porous ceramsite. The method particularly comprises the following steps: preparing a hydrotalcite-like material by taking manganese nitrate, aluminum nitrate and urea as raw materials, and mixing the hydrotalcite-like material and silicon carbide to prepare a foaming agent; preparing porous ceramic by taking plant powder, zeolite powder, polyvinyl alcohol, deionized water, montmorillonite, aluminum nitride fiber and urea as raw materials; and preparing a green body by taking waste glass powder, modified porous ceramsite, a cosolvent, the foaming agent and a foaming accelerant as raw materials through the steps of grinding, mixing and performing compression molding, placing the green body into a muffle furnace and performing sintering treatment to prepare the foam glass. The foam glass prepared with the method has high mechanical property and excellent sound-absorbing and heat-insulating properties.

Description

Technical field: [0001] The invention relates to the field of glass preparation, in particular to a method for preparing foam glass by using waste glass and porous ceramsite. Background technique: [0002] Foam glass is a special glass material manufactured artificially. It can be crushed and mixed evenly to form batch materials by quantitative cullet, foaming agent and additives. It is put into a mold, and then preheated, melted, foamed and annealed. Made by other techniques. The density and porosity of commercial foam glass products are 0.1-0.3g / cm respectively 3 and 85-95%. Foam glass has many excellent properties such as light weight, high strength, heat insulation and cold preservation, waterproof and anti-corrosion, non-toxic and non-combustible, chemical stability, insect-proof and anti-bacterial, ecological and environmental protection, etc. At the same time, it also has commercial advantages such as low transportation cost, easy processing and installation, and g...
