Abstract

PURPOSE: To provide a fireproofing agent which excels in weathering resistance and improves the fire resistance of a panel perse, by a method wherein an expandable inorg. matter capable of forming an expanded layer at an elevated temperature and an adsorptive powder, are enclosed in an impermeable wall membrane substance.
CONSTITUTION: An expandable inorg. matter 1 such as a borate, a silicate or disodium hydrogenphosphate and an adsorptive powder 2 composed of activated carbon or silica gel, are enclosed in a wall membrane substance 3 such as polyethylene or vinyl chloride in the form of a sheet. The expandable inorg. matter 1 can form an inorg. expanded layer by releasing water of crystallization contained in the inorg. matter at an elevated temperature to expand the inorg. matter. The adsorptive powder 2 prevents the rise in pressure within gaps by adsorbing water vapor produced from the expandable inorg. matter 1, when the inorg. matter 1 is molten at a temp. of 70W80°C. Alternatively, a wick material 4 such as a cloth or glass fiber sheet is impregnated with said expandable inorg. matter. The resulting wick material is cut in small pieces. The pieces together with the adsorptive powder 2 are enclosed in the wall membrane substance 3. A plurality of the fireproofing agent A thus obtd. can set in parallel to form a sheet.
