Manufacturing and construction method of light-weight fire resistance foaming ceramic insulation for preventing fire spread on exterior insulation layer

摘要

The present invention relates to a method for manufacturing a lightweight fire-resisting foamed ceramic insulating material for preventing fire spread of a building outer wall insulation layer, and more particularly, to a method for effectively suppressing fire spread of a building outer wall insulation layer, So that the fire stability can be greatly improved. The present invention relates to a glass sludge comprising 75 to 95% by weight of glass sludge selected from waste glass powder, glass polishing sludge or a mixture thereof; 1 to 20% by weight of an additive selected from fly ash, silica powder, waste concrete fine powder, stone powder, perlite powder, or a mixture of two or more species; 1 to 5% by weight of sodium silicate as a blending and blending agent; In order to form pores in the softened sludge by generating bubbles at a temperature higher than the softening point of the glass sludge in a state surrounded by the glass sludge, any one of carbon black, calcium carbonate and magnesium carbonate or a mixture of two or more species 0.1 to 5.0% by weight of the selected inorganic foaming agent; And 1 to 10% by weight of a melting point depressant selected from any one of boron, sodium carbonate or a mixture thereof to lower the melting point of the glass sludge.
