A MANUFACTURING METHOD OF HEART INSULATING MATERIAL FOAMED GLASS USING BOILING METHOD, AND THERFOR HEART INSULATING MATERIAL FOAMED GLASS

摘要

PURPOSE: A manufacturing method of a heat insulating material foam glass using a boiling process is provided to remarkably reduce the manufacturing cost while obtaining excellent performance for heat insulating material. CONSTITUTION: A heat insulating material foam glass using a boiling process is manufactured of glass powder of 60-100Mm, water, 10-30vol% of liquid sodium silicate, and 0.1vol% or less of silicon-based foaming agent. A manufacturing method of the heat insulating material using a boiling process comprises a step of preparing the glass powder of 60-100Mm; a step of mixing the glass powder with the 10-30vol% of liquid sodium silicate, and 0.1vol% or less of silicon-based foaming agent; and a step of filling a sealed container with the mixture, radiating microwaves, boiling the mixture for specific time, and drying foamed glass.
