[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a novel sealing strip with a flame-retardant structure, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it includes a flame-retardant expansion structure 1, which includes an expansion component 11. An antistatic coating layer 12 is sprayed on the expansion component 11. A fire-resistant expansion serrated rubber strip 13 is fixed on the expansion component 11. An adhesive layer 14 is fixed on the lower side of the expansion component 11. The expansion component 11 includes a first fire-resistant expansion material 111. A second fire-resistant expansion material 112 is fixed on the lower side of the first fire-resistant expansion material 111. An expansion cavity 113 is opened in both the second fire-resistant expansion material 112 and the first fire-resistant expansion material 111.

[0021] The first refractory expansion material 111 and the second refractory expansion material 112 have the same volume. Both the first refractory expansion material 111 and the second refractory expansion material 112 are provided with expansion cavities 113, which are arranged in a U-shape.

[0022] Furthermore, two sets of refractory expansion serrated rubber strips 13 are fixed on both the first refractory expansion material 111 and the second refractory expansion material 112. The two sets of refractory expansion serrated rubber strips 13 are symmetrically arranged about the central axis of the first refractory expansion material 111 and the second refractory expansion material 112.

[0023] In the above scheme, in the event of a severe fire, the first fire-resistant expansion material 111 and the second fire-resistant expansion material 112 expand after combustion, thereby sealing the gaps in doors and windows and the expansion cavity 113, thus better isolating high temperature and dense smoke, preventing dense smoke from entering the room, gaining more time for emergency response, and ensuring the safety of people inside. The antistatic coating layer 12 plays a role in preventing static electricity. The fire-resistant expansion serrated rubber strip 13 also expands in the event of a fire to ensure a sealing effect. The sealing strip is fixed by the adhesive layer 14.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a flame-retardant and sound-insulating component 2 is fixed on the flame-retardant expansion structure 1. The flame-retardant and sound-insulating component 2 includes a flame-retardant layer 21 and a sound-insulating layer 22.

[0025] Among them, the flame retardant layer 21 includes a polypropylene modified flame retardant film, silicone halogen-free flame retardant fiber, aluminum silicate fiber, asbestos fiber and flame retardant filler, thereby ensuring the flame retardant effect.

[0026] Specifically, the sound insulation layer 22 is made of EPDM rubber to ensure sound insulation performance;

[0027] In the above scheme, the flame-retardant layer 21 plays a flame-retardant role with the assistance of the flame-retardant layer 21, and the sound-insulating layer 22 plays a supporting sealing role for the entire sealing strip with the assistance of the sound-insulating layer 22, thereby playing a better sound-insulating role.

[0028] like Figure 1, Figure 2 , Figure 3 and Figure 4 As shown, a sealing component 3 is fixed on the upper side of the flame-retardant and sound-insulating component 2. The sealing component 3 includes a sealing strip body 31, a buffer cavity 33 is provided on the sealing strip body 31, and a flame-retardant coating layer 32 is sprayed on the surface of the sealing strip body 31. The sealing strip body 31 is semi-circular.

[0029] The sealing strip body 31 is made of high-quality graphene and rubber raw materials. When a fire occurs, the sealing strip body 31 burns and expands to ensure the sealing of doors and windows. Moreover, the sealing strip body 31 has no odor after burning, ensuring human health.

[0030] Specifically, the fire resistance limit of flame-retardant coating layer 32 is usually around 2 hours;

[0031] In the above scheme, the sealing strip body 31 plays a sealing role with the assistance of the sealing strip body 31. The buffer cavity 33 on the sealing strip body 31 plays a buffering role. The flame retardant coating layer 32 on the sealing strip body 31 plays an auxiliary flame retardant role. If the temperature is too high, the sealing strip body 31 expands to seal the gaps in the doors and windows, ensuring the sealing effect and preventing excessive harmful gases from entering the room and affecting the safety of people's lives.

[0032] Working principle: When using this new type of sealing strip with flame-retardant structure, when the external power supply is turned on, the sealing component 3 plays an auxiliary role in flame retardancy and sealing, the flame-retardant and sound-insulating component 2 plays a role in flame retardancy and sound insulation, and the flame-retardant expansion structure 1 plays a role in flame retardant expansion.
