Abstract

The invention discloses thermal-insulation foam glass and a preparation method thereof and belongs to the technical field of building materials. The preparation method disclosed by the invention comprises the steps: firstly, stirring and mixing a calcium hydroxide saturated solution and nano activated carbon to obtain a primary mixed solution; then introducing carbon dioxide into the primary mixed solution to obtain a secondary mixed solution; then filtering and drying to obtain coated nano activated carbon; mixing and ball mixing waste glass and plant ash to obtain mixed powder; stirring and mixing the mixed powder, the coated nano activated carbon and a fluxing agent, compression molding, spraying a release agent, preheating, sintering, foaming, annealing, dipping and drying to obtain the thermal-insulation foam glass. The thermal-insulation foam glass disclosed by the invention has excellent thermal-insulation performance.

Description

technical field [0001] The invention discloses a heat-insulating foam glass and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] In recent years, with the improvement of people's quality of life, people's awareness of environmental protection has been continuously enhanced, and due to the shortage of natural resources, the reuse of waste glass and industrial waste has been paid more and more attention. Foam glass is a kind of artificially manufactured porous material, which is filled with countless tiny uniformly connected or closed pores of glass material. It has high mechanical strength, stable thermal performance, low thermal expansion coefficient, no combustion, no deformation, long service life, wide working temperature range, strong corrosion resistance, no radioactivity, no water absorption, no moisture permeability, no pests, easy It has the advantages of sawing and convenient construction, and is an...
