[0018] The present invention will be further described below with reference to the embodiments.

[0019] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0020] Please see Figure 1 This utility model provides a fire door with soundproofing function, including a door frame 1 and a door panel 2, which are movably installed together and connected by a hinge 3. A handle is fixedly connected to the front of the door panel 2.

[0021] In this embodiment, the surfaces of the door frame 1 and the door panel 2 are coated with fire-retardant paint during production, which enhances the fire resistance of the fire door.

[0022] Please see Figure 1 and Figure 3 The door panel 2 includes an outer frame 21, a barrier layer 22 is provided in the middle of the outer frame 21, the outer frame 21 is made of flame retardant board material, the barrier layer 22 is a sand layer, a sound-absorbing panel 23 is provided on the side of the barrier layer 22, the sound-absorbing panel 23 is made of polyester fiber material, and the sound-absorbing panel 23 is fixedly connected to the outer frame 21. A sound-absorbing layer 24 is provided on one side of the sound-absorbing panel 23, and the sound-absorbing layer 24 is made of polyurethane soft foam.

[0023] In this embodiment, since the outer frame 21 is made of flame-retardant board, and the existing flame-retardant board has flame-retardant, smoke-suppressing, corrosion-resistant and insect-proof properties, it can significantly slow down the burning speed and reduce the spread of flames when a fire occurs. The use of sand as a barrier layer 22 can not only block the transmission of sound, but also prevent the flames from burning through the door panel 2 when a fire occurs. The sound-absorbing board 23 made of polyester fiber material has sound absorption, flame retardant, heat insulation and heat preservation properties, which can play a role in sound absorption and fire prevention. At the same time, the sound-absorbing layer 24 is a polyurethane soft foam with an open-cell structure, which has low density, sound absorption and heat preservation properties, which can further enhance the sound absorption effect of the fire door.

[0024] Please see Figure 1 and Figure 3 A flame-retardant layer 25 is provided on one side of the sound-absorbing layer 24. The flame-retardant layer 25 is made of glass fiber material and is in contact with the inner side of the outer frame 21. There are two sound-absorbing panels 23, two sound-absorbing layers 24 and two flame-retardant layers 25. The barrier layer 22 is filled between the two sound-absorbing panels 23 and the sound-absorbing layer 24 is filled between the sound-absorbing panel 23 and the flame-retardant layer 25.

[0025] In this embodiment, because the fiberglass material has flame-retardant and high-temperature resistant properties, it performs well in high-temperature environments and can maintain structural stability, without melting or burning. When the outer frame 21 is burned through by flames during a fire, the flame-retardant layer 25 of the fiberglass material can further block the fire, thereby enhancing the fireproof effect of the fire door.

[0026] The working principle and usage process of this utility model are as follows: First, since the outer frame 21 is made of flame-retardant board, and the existing flame-retardant board has flame-retardant, smoke-suppressing, corrosion-resistant and insect-proof properties, it can significantly slow down the burning speed and reduce the spread of flames when a fire occurs. When the outer frame 21 is burned through by flames, the flame-retardant layer 25 of glass fiber material can further block the fire, thereby enhancing the fireproof effect of the fire door.

[0027] Next, the sound-absorbing panel 23 made of polyester fiber material has the characteristics of sound absorption, flame retardancy, heat insulation and heat preservation, which can play the role of sound absorption and fire prevention. At the same time, the sound-absorbing layer 24 is a polyurethane soft foam with an open-cell structure, which has the properties of low density, sound absorption and heat preservation, which can further enhance the sound absorption effect of the fire door.

[0028] Finally, sand particles are used as a barrier layer 22, which not only blocks the transmission of sound, but also prevents flames from burning through the door panel 2 in the event of a fire, thereby improving the soundproofing and flame-retardant effect of the fire door.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
