Fire disaster fireproof door

The utility model discloses a fire disaster fireproof door which comprises a door leaf and a smoke detector arranged on the door leaf. The door leaf comprises a gypsum board, an asbestos board, a perlite sound-absorbing board, a flameproof board, an inorganic heat-absorbing board and an exterior board, the asbestos board, the perlite sound-absorbing board, the flameproof board, the inorganic heat-absorbing board and the exterior board are stacked outwards sequentially from two sides of the gypsum board, the smoke detector comprises a smoke probe and atomizing nozzles, and the atomizing nozzles are connected with a water tank. The fire disaster fireproof door has the advantages that the fireproof door can play a role in sound insulating and reducing; when fire danger occurs, an inorganic heat-absorbing board layer is arranged in a face board of the door leaf, can release water vapour when being heated to a certain degree and absorbs heat in the process of releasing the water vapour, so that cooling effect is realized; the smoke probe after sensing smoke can start the atomizing nozzles, atomized water drops can remove the smoke around the door to enable escape personnel to smoothly pass the fireproof door, so that escape time is seized.
