ARTICLE OR COMPONENT CONTAINING CURED BODY OF SELF-CURABLE POWDER

PROBLEM TO BE SOLVED: To provide a fireproof sash material, a fireproof sash frame, or a fireproof window, which maintains strength when heated to high temperature due to fire so as to prevent a glass pane from falling off, allows infilled material not to leak out resulting from erroneous boring or minimal damage, and has sufficient strength for normal use without metal reinforcement, with high productivity.SOLUTION: A fireproof material 16 is made from self-curable powder which is produced from a mixture of 100 pts.mass of an aggregate powder of inorganic hollow particles, 2 to 17 pts.mass of a binder composition of alkaline aqueous solution or dispersion liquid of water soluble phenol resin with a solid content of the water soluble phenol resin of 10 to 60 mass%, and a curing agent with the amount necessary for curing the water soluble phenol resin contained in the binder composition. The cavity part 11 of a sash material or a sash frame 4 is filled with the fireproof material 16, which is cured at normal temperature so that the cured body is used as a heat-resistant component and also as a reinforcement.
