[0019] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0020] Reference Figure 1-4 A fireproof door of an energy box includes a door frame 10, wherein the door frame 10 includes a door frame skeleton, wherein the door frame skeleton is a rectangular frame composed of upper and lower horizontal beams and left and right vertical beams, wherein the door frame skeleton is a hollow skeleton, wherein a pearlite wool layer is filled in the hollow skeleton, and in one embodiment, the side of the hollow skeleton close to the door leaf 20 is stepped, so that the door leaf 20 can be installed within the space defined by the hollow skeleton and kept flush, and the door frame 10 adopts a hollow skeleton filled with a pearlite wool layer, and has good heat insulation measures, so that the heat insulation is sufficient to prevent the heat of the fire-receiving surface from being directly or indirectly transferred to the back-fire surface, causing overheating; the door frame 10 has a reasonable structure, and the surface area of ​​the fire-receiving surface is small, so that the heat transferred to the outside is small or the surface area of ​​the back-fire surface is large, and the heat dissipation effect is sufficient.

[0021] The inner side of the door frame skeleton and the side in contact with the door leaf 20 have a ring-shaped U-shaped groove, and a ring-shaped door material pad 60 is provided in the U-shaped groove. Specifically, the U-shaped groove and the door frame skeleton are an integrated structure, and the U-shaped groove is formed by bending when the door frame skeleton is formed. The door material pad 60 includes a composite skeleton installed in the U-shaped groove, and a semicircular hollow sealing portion is provided on the composite skeleton to be in contact with the panel of the door leaf 20. The door material pad 60 has a good sound insulation effect, a certain degree of air tightness, and an auxiliary fire prevention function.

[0022] A sealing strip 70 is also provided on the inner side of the door frame skeleton, and the sealing strip 70 is fitted with the panel of the door leaf 20. In one embodiment, sealing strips 70 are provided on three side surfaces of the inner side of the door frame skeleton, and the sealing strip 70 includes an aluminum alloy skeleton and a rubber layer. The sealing strip 70 is crucial to the air tightness of the fire door. Whether the sealing strip 70 is made of chloroprene rubber or EPDM rubber, it can meet the air tightness requirements, but neither has fireproof ability. Ordinary sealing strips 70 cannot meet the air tightness requirements. Through experiments, silicone rubber is currently the most ideal sealing strip 70, which can withstand temperatures of 600°C to 700°C and has the dual properties of high resilience and flame retardancy.

[0023] The seal adopts a double-channel U-shaped seal type of door material gasket 60 and sealing strip 70. The fireproof sealing strip is not easily damaged and the seal is reliable, ensuring no water vapor leakage and isolating outdoor toxic and harmful gases.

[0024] The door leaf 20 is provided in the door frame 10. One side of the door leaf 20 is connected to the door frame 10 via a hinge 40. The other side of the door leaf 20 is opened and closed with the door frame 10 via a lock 50. The door leaf 20 is filled with rock wool. Specifically, the door leaf 10 is composed of a fireproof sealing strip 80, a fireproof board, a reinforcing rib, a panel, and a back panel. A welded fireproof board is arranged between the panel and the back panel, and reinforcing ribs are arranged between the fireproof board and the panel and the back panel. The hollow of the door leaf is filled with rock wool to serve as a partition. A fireproof sealing strip 80 is arranged on the outer side of the fireproof board to fit with the inner side of the door frame. The intumescent fireproof sealing strip 80 isolates open flames and also protects the silicone rubber from damage to meet the sealing requirements. Through the fire test, the intumescent fireproof sealing strip 80 is adopted around the door frame 10. In this way, the fireproof sealing strip 80 can expand rapidly when encountering open flames. Under normal circumstances, it can expand to 20 times of its original volume, which can effectively prevent fire from penetrating and protect the fireproof silicone rubber airtight strip.

[0025] The top of the door leaf 20 is connected to the door frame 10 via a door closer 30 .

[0026] The fireproof door fully meets the requirement of fireproof and heat insulation of not less than one hour. Refractory material is arranged in the box-shaped hollow of the inner and outer layers of steel plates of the fireproof door. An expandable fireproof sealing strip 80 is adopted around the door frame. The fireproof sealing strip 80 can expand rapidly when encountering an open flame. Generally, it can expand to 20 times of its original volume, which can effectively prevent fire from penetrating and protect the fireproof silicone rubber sealing strip.

[0027] The door leaf 20 and the door frame 10 may also be powder-coated, with the dry film thickness of the epoxy zinc-rich primer not less than 60um, the dry film thickness of the polyester powder not less than 60um, and the total thickness not less than 120um; or the dry film thickness of the epoxy primer not less than 70um, the dry film thickness of the polyester powder not less than 70um, and the total thickness not less than 140um. The test panel was subjected to a 720-hour neutral salt spray test, and the results met the acceptance requirements of ISO12944-6; the coating adhesion was tested by the cross-cut method according to ASTMD3359, and the results met the 5B grade.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
