The present invention relates to a non-combustible composition for fire doors (walls), fire doors (walls) using the same, and a method for manufacturing the same. More specifically, 1 to 80% by weight of organic or inorganic fibers, 1 to 80% by weight of fly ash or bottom ash Nonflammable composition for fire doors (walls) comprising%, 1 to 80% by weight of flame retardant, 1 to 30% by weight of hardening flame retardant resin, and 1 to 40% by weight of non-combustible hollow filler, and fly ash or bottom ash in the composition, Flame retardant and curing flame retardant resin is mixed, and the organic fiber or inorganic fiber is dispersed / injected into the mixture, pulverized / mixed, and finally the non-combustible hollow body is mixed with a mixer using air, and then the mixture is pressed under high pressure. Compression molding into a plate or a square using to form a frame of the fire door (wall) with the plate and / or the shell, and to embed a non-combustible core material therein of the fire door (wall) It relates to a manufacturing method and a non-combustible fire door (wall) produced by the above method.n n n According to the present invention, since 1 to 70% by weight of the non-combustible composition for fire doors (walls) can recycle waste materials, the production cost is low, and all the constituent compositions generate flames and toxic gases even when contacted by different flames. It is suitable for use as building finishing and interior materials. |
