Problems solved by technology

[0002] Foam glass is an inorganic non-metallic glass material made of glass, foaming agent and other components after being finely crushed and evenly mixed, then melted at high temperature, foamed and annealed. The role of the glass material, coupled with the fact that the long-term performance of the glass material does not degrade, makes it very popular in many harsh environments, and is widely used in the fields of wall insulation, petroleum, chemical industry, sound insulation, etc.; however, the existing foam glass although It has a certain thermal insulation performance, but the thermal insulation effect cannot meet the needs of the market. It is necessary to further improve the existing foam glass to improve its thermal insulation performance

Abstract

The invention discloses a preparation method of heat-preservation foam glass, and relates to the technical field of glass processing. The heat-preservation foam glass is prepared from quartz glass, nanometer zeolite powder coated with bismuth oxide, potassium chloride, sodium carbonate, calcium oxide, aluminium oxide, zinc oxide, acidized bentonite and a foaming agent. By adopting the nanometer zeolite powder coated with bismuth oxide, the foaming temperature and crystallization tendency within the foaming temperature range can be reduced effectively, the synergistic effect of the nanometer zeolite powder and the acidized bentonite can be achieved, the viscosity change rate of the glass within the foaming temperature range can be substantially decreased, and therefore the firing temperature range is widened; the prepared foam glass has an even and stable foam diameter, and the heat preservation performance of the foam glass can be effectively improved.
