Description

Fire door with fire-retardant structure Technical Field The utility model relates to the technical field of fire doors, in particular to a fire door with a fire-retarding structure. Background Fire doors are a type of building fire protection that is specifically designed to prevent the spread of fire and smoke, and are typically installed in critical locations such as fire partitions, stairwells, hallways, etc. of a building. The core function is that when fire happens, through the self fire-proof structure and sealing performance, the fire source and the high-temperature smoke are effectively isolated within a certain time, and precious time is striven for personnel evacuation and fire rescue. In the prior art, the fire-retardant fire door mainly relies on physical separation and material fire resistance to realize the fire-retardant function to do not possess the function of initiatively putting out a fire, expose in the high temperature environment for a long time, say the door opposite side is burnt continually, and the fire door probably leads to deformation or sealed inefficacy because of heat conduction, increases the risk of breaking through the fire prevention separation.
