Background

A fire door is a door that can meet the requirements of fire stability, integrity and thermal insulation within a certain period of time. It is a fire-proof partition with certain fire resistance, which is arranged in fire-proof subareas, evacuation staircases, vertical shafts and the like. The fireproof door has the functions of a common door, has the functions of preventing the fire from spreading and the smoke from diffusing, and can prevent the fire from spreading within a certain time to ensure the evacuation of people. However, the existing fireproof door has short fireproof time, and when a fire is diffused, the door can be easily sintered due to the high temperature of the fire, so that the time for evacuating people is shortened; in addition, some existing fireproof doors do not have a cooling function, heat easily penetrates through the fireproof doors to enter an escape channel due to the high temperature of fire, serious threats are brought to escape people (when the escape people wait for rescue in the escape channel, if the heat is too large, the escape people can suffocate, and the people can die seriously), and therefore the fireproof doors capable of reducing the temperature and being long-acting and fireproof are provided.
