Abstract

Technical Field
[0001] The utility model relates to the technical field of fireproof doors, in particular to a core board of a fireproof door. Background Art
[0002] Fire doors are doors with fire resistance, which can buy time for people to escape from fire, prevent fire from spreading, delay the spread of fire and prevent high temperature. Therefore, fire doors play a vital role in fire. Fire doors are widely used in many fields such as residential houses, ships, construction, chemical industry, mechanical engineering, etc. The core board of fire doors is the main component of fire doors. At present, the core boards of most fire doors sold in the market are made of solid core pressed by fireproof materials. Solid core boards use more materials, are costly, and have average insulation effect.
[0003] However, the current fire doors have a poor cooling effect when heated. The heat will be transferred along the steel plate to the door core board. The door core board will deform after being heated, which can easily cause the fireproof material of the door core board to crack, seriously affecting the fireproof effect of the fire door. In addition, in the past, fire doors could only block flames and could not perform auxiliary fire extinguishing treatment. Therefore, this application proposes a fire door core board to solve this problem.
[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
