Abstract

The invention discloses a fireproof door. The fireproof door comprises a rectangle metal casing provided with a discharging port in front and is characterized by further comprising a top plate, a base plate, a fire-resisting plate, a material box and sealing plugs, wherein the top plate and the base plate are arranged at the top end and the bottom end of the metal casing, and the fire-resisting plate, the material box and the sealing plugs are arranged between the top plate and the base plate from back to front. The material box is provided with a box port in butted joint with the discharging port, a dry powder extinguishing agent is filled inside the material box, and an encapsulation film is arranged at the position of the box opening. The sealing plugs are plugged into the box port and the discharging port. The fireproof door has the advantages of improving the fireproof performance, having a certain fire extinguishing function, prolonging fire propagation time and increasing time for people escape.

Description

technical field [0001] The invention relates to a fireproof building material, in particular to a fireproof door with fireproof and fire extinguishing functions. Background technique [0002] Generally, fire doors are widely used in many fields such as residential houses, ships, buildings, chemicals, and mechanical engineering. Fire doors refer to doors with fire-resistant properties, which buy time for people to escape from the fire in the event of a fire, prevent the spread of fire, delay the spread of fire, and be fire-resistant for a certain period of time. Therefore, fire doors play a vital role in the event of a fire. The fire performance of metal doors is one of the concerns of people. The existing metal door has single function and poor fire performance. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a fire door capable of preventing and extinguishing fire. [0004] In or...
