MULTI-PURPOSE LIGHTWEIGHT FOAM COMPOSITION FOR BUILDINGS EXCELLENT IN COMPRESSIVE STRENGTH, HEAT INSULATION PROPERTY, SOUND INSULATION PROPERTY, AND SOUND ABSORPTION PROPERTY AND PREPARATION METHOD THEREOF

摘要

PURPOSE: A multi-purpose lightweight foam composition for buildings is provided, which is excellent in a compressive strength, a heat insulation property, a sound insulation property, and a sound absorption property. And a method is also provided to produce the multi-purpose lightweight foam composition. CONSTITUTION: The multi-purpose lightweight foam composition is produced by the method comprising the steps of: mixing 2-10wt% of magnesium oxide, 4-16wt% of borax, 67-91wt% of sodium silicate, and 3-8wt% of a foaming agent; drying the mixture to remove moisture; grinding the dried mixture to 6-30mesh; injecting the ground mixture into a mold(1); calcining by putting the mold(1) in a micro electromagnetic wave device.
