Steel heat insulation fireproof door leaf

The utility model relates to the technical field of fireproof doors, in particular to a steel heat-insulation fireproof door leaf which comprises a door frame, two door plates hinged to the middle of the door frame, flame-retardant assemblies installed in the door plates, sliding rods connected in the door plates in a sliding mode, sliding plates fixedly connected to the upper sides of the sliding rods, and push plates fixedly connected to the bottoms of the sliding rods. A mounting plate is fixedly connected to the upper side in the door plate, a plurality of nozzles are mounted on the front side of the mounting plate, a first cavity is formed in the bottom side in the door plate and filled with expanded graphite, and a second cavity is formed in the upper side in the door plate and filled with a dry powder extinguishing agent. According to the steel heat-insulation fireproof door leaf, by arranging the expanded graphite, the expanded graphite expands rapidly after being heated and generates gas, the push plate and the sliding rod are pushed, and therefore the dry powder fire extinguishing agent is pushed to be sprayed out through the spray head, and rapid automatic fire extinguishing is achieved. By means of the automatic response mechanism, the rapid response capacity in the initial stage of the fire disaster is greatly improved, and losses possibly caused by the fire disaster are reduced.
