Description

Technical Field

[0001] This application relates to the field of sound-absorbing panels, and in particular to a fire-resistant and environmentally friendly polyester fiber sound-absorbing panel. Background Technology

[0002] Sound-absorbing panels are an ideal sound-absorbing decorative material. They possess advantages such as sound absorption, heat insulation, moisture resistance, mildew resistance, easy dust removal, mosaic capability, simple construction, good stability, good independence, and high cost-effectiveness. A wide variety of colors are available to meet different style and level sound-absorbing decorative needs. They are commonly used in concert halls, theaters, recording studios, broadcasting studios, monitoring rooms, conference rooms, gymnasiums, exhibition halls, dance halls, KTV rooms, and other similar settings.

[0003] In existing technologies, sound-absorbing panels serve to absorb and insulate sound in special environments, such as KTVs or dance halls. However, these environments are high-risk areas for fires, so traditional sound-absorbing panels do not have good fire protection measures.

[0004] A search revealed a fire-resistant and environmentally friendly polyester fiber sound-absorbing board (publication number: CN217537388U) in Chinese patent literature, but it still has the following defects: Although the aforementioned fireproof and environmentally friendly polyester fiber sound-absorbing panels have achieved good electrical insulation and fire resistance, thus improving safety, they still have the problem that, despite having fireproofing measures, the fireproofing effect is not good. Utility Model Content

[0005] To address the lack of effective fire protection in traditional sound-absorbing panels, this application provides a fire-resistant and environmentally friendly polyester fiber sound-absorbing panel.

[0006] This application provides a fireproof and environmentally friendly polyester fiber sound-absorbing board using the following technical solution: A fireproof and environmentally friendly polyester fiber sound-absorbing panel includes a first sound-absorbing panel, a sealing frame installed at the front end of the first sound-absorbing panel, a second flame-retardant panel installed inside the sealing frame, and a second sound-absorbing panel at the front end of the second flame-retardant panel. Silicone layers are installed through the front end of the second flame-retardant panel at equal intervals. A first filling layer is connected to the rear end of the silicone layer. The first filling layer is filled with flame-retardant particles. A second filling layer is installed inside the rear end of the second sound-absorbing panel, and the second filling layer is filled with sound-insulating particles.

[0007] By adopting the above technical solutions, multiple sound insulation protections, and multiple measures to protect against open flames, the safety and practicality of the device during use are further improved.

[0008] Preferably, the rear ends of the first sound-absorbing panel and the first sound-absorbing panel are symmetrically provided with corresponding insertion cavities, and a connecting frame is inserted into the interior of the insertion cavity.

[0009] By adopting the above technical solution, the connecting frame is inserted into the insertion cavity, and the first sound-absorbing plate and sealing frame are fixed and limited by the insertion, thereby improving flexibility.

[0010] Preferably, the two ends of the connecting frame are each equipped with a second limiting protrusion at equal intervals, and the outer side wall of the second limiting protrusion abuts against the outer side wall of the first limiting protrusion. The first limiting protrusion is installed at equal intervals at one end of the flexible sheet, and the flexible sheet is symmetrically installed inside the insertion cavity.

[0011] By adopting the above technical solution, the outer wall of the second limiting protrusion abuts against the outer wall of the first limiting protrusion, thereby self-limiting the connecting frame.

[0012] Preferably, the rear end of the connecting frame is connected to the front end of the positioning plate, and the positioning plate has symmetrically arranged connecting bolts connected by through-threaded connections.

[0013] By adopting the above technical solution, the positioning plate is fixedly connected to the installation area with the connecting bolts, thereby completing the positioning and installation of the connecting frame and the positioning plate.

[0014] Preferably, a male hook and loop fastener is attached to the rear end of each silicone layer, and a female hook and loop fastener is attached to the rear end of each male hook and loop fastener, with the female hook and loop fastener installed at one end of the first filler layer.

[0015] By adopting the above technical solution, the first filling layer is bonded by male and female hook and loop fasteners, which allows the first filling layer to be disassembled and the filling material of the inner first filling layer to be replaced.

[0016] Preferably, the male hook and loop fastener, the female hook and loop fastener, and the first filling layer are all provided with through cavities, and a first flame-retardant plate is inserted into the through cavity. The first flame-retardant plate is installed at equal intervals at the front end of the first sound-absorbing plate.

[0017] By adopting the above technical solution, the first flame-retardant board can not only further improve the flame-retardant effect, but also resist the silicone layer, providing resistance to the second filling layer and making it fit better with the second sound-absorbing board.

[0018] Preferably, the front end of the second sound-absorbing panel is coated with a sound-insulating coating.

[0019] By adopting the above technical solution, the sound insulation coating applied to the front end of the second sound-absorbing panel helps to further improve the overall sound insulation effect of the device.

[0020] Preferably, reinforcing blocks are installed at equal intervals at the rear end of the second sound-absorbing panel, and one end of the reinforcing block abuts against one end of the second filling layer.

[0021] By adopting the above technical solution, the reinforcement block resists the second filling layer, thereby effectively preventing the accumulation of filler material inside the second filling layer.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. During use, this utility model has a good fire-retardant effect. It forms a triple protection effect through the first flame-retardant plate, the second flame-retardant plate and the first filling layer, which can effectively complete the fire prevention operation, further reduce the spread of fire source and improve the safety factor. This improves the practicality and safety of the device. Compared with traditional fire prevention methods, this fire prevention method has a better blocking effect and a better safety factor. 2. The connecting frame is aligned with the insertion cavity and the insertion is completed. After the insertion is completed, the outer wall of the connecting frame abuts against the outer wall of the second limiting protrusion, thereby making the connecting frame self-limited with the first sound-absorbing plate and the sealing frame. This method can improve the efficiency of disassembly and assembly during subsequent maintenance and replacement, and eliminates the traditional screw-type fixing. Thus, disassembly and assembly can be completed without disassembly tools, improving practicality and convenience. Attached Figure Description

Detailed Implementation

[0025] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0026] This application discloses a fireproof and environmentally friendly polyester fiber sound-absorbing board.

[0027] Reference Figures 1-4 and Figure 7 A fireproof and environmentally friendly polyester fiber sound-absorbing panel includes a first sound-absorbing panel 1. A hollow sealing frame 2 is fixedly connected to the front end of the first sound-absorbing panel 1. Both the first sound-absorbing panel 1 and the sealing frame 2 have symmetrically opened insertion cavities 3 at their rear ends. Flexible sheets 4 are symmetrically fixedly connected inside the insertion cavities 3. First limiting protrusions 5 are fixedly connected at equal intervals to the corresponding outer walls of the flexible sheets 4. The outer walls of the first limiting protrusions 5 abut against the outer walls of the second limiting protrusions 9. Both the second limiting protrusions 9 and the first limiting protrusions 5 are semi-cylindrical structures. The top and bottom ends of a connecting frame 8 with a concave structure are fixedly connected at equal intervals to the second limiting protrusions 9. One end of the connecting frame 8 is fixedly connected to one end of a positioning plate 6. Connecting bolts 7 are symmetrically threaded through the front end of the positioning plate 6.

[0028] During use, the positioning plates 6 connected to the connecting frame 8 are installed to the designated area using connecting bolts 7, and the spacing between the positioning plates 6 matches the spacing between the insertion cavities 3. During installation, the insertion cavities 3 are aligned with the connecting frame 8 and inserted. After insertion, the outer wall of the connecting frame 8 abuts against the outer wall of the second limiting protrusion 9, thereby self-limiting the connecting frame 8, the first sound-absorbing plate 1, and the sealing frame 2. This method facilitates disassembly and assembly during subsequent maintenance and replacement, thereby improving work efficiency.

[0029] Reference Figures 1-5The front end of the first sound-absorbing panel 1 is fixedly connected with a first flame-retardant panel 10 at equal intervals, and the first flame-retardant panel 10 is inserted into the cavity 16 and abuts against one end of the silicone layer 12. The silicone layer 12 is fixedly connected through the front end of the second flame-retardant panel 11 at equal intervals, and the second flame-retardant panel 11 is fixedly connected to the inside of the sealing frame 2. The end of the silicone layer 12 near the first flame-retardant panel 10 is fixedly connected with a female hook and loop fastener 14 with a velvet structure, and the end of the female hook and loop fastener 14 is glued with a male hook and loop fastener 13 with a hook structure. One end of the male hook and loop fastener 13 is fixedly connected to one end of the first filling layer 15, and the interior of the first filling layer 15 is filled with flame-retardant particles. The first sound-absorbing panel 1 is made of fireproof and environmentally friendly polyester fiber material. The male hook and loop fastener 13, the female hook and loop fastener 14 and the interior of the first filling layer 15 are all provided with a cavity 16. The first filling layer 15 is made of natural protein fiber material.

[0030] During use, after the second flame-retardant plate 11 is installed inside the sealing frame 2, the first flame-retardant plate 10 will be inserted into the male hook and loop fastener 13, the female hook and loop fastener 14 and the first filling layer 15, and will abut against one end of the silicone layer 12. In this way, the first filling layer 15 is filled with flame-retardant particles, which can effectively retard flames when an open flame is present, and together with the first flame-retardant plate 10, further block the spread of open flames, improving practicality and safety.

[0031] Reference Figures 1-6 The front end of the second flame-retardant plate 11 is provided with a second sound-absorbing plate 17 fixedly connected inside the sealing frame 2, and the front end of the second sound-absorbing plate 17 is coated with a sound-insulating coating 18, which is composed of oily resin, porous sound-absorbing filler and additives. The rear end of the second sound-absorbing plate 17 is fixedly connected with reinforcing blocks 20 at equal intervals, and one end of the reinforcing block 20 abuts against one end of the second filling layer 19 fixedly connected inside the rear end of the second sound-absorbing plate 17. The second filling layer 19 is filled with sound-insulating particles, which are inorganic porous particles. The end of the second filling layer 19 away from the reinforcing block 20 abuts against the front end of the silicone layer 12. The second filling layer 19 is made of natural protein fiber material. The sound-insulating coating 18 is composed of elastic resin, porous filler and filler.

[0032] During use, the second sound-absorbing panel 17, the sound-insulating coating 18, and the second filling layer 19 work together to form a triple sound-absorbing structure. The reinforcing block 20 strengthens the second sound-absorbing panel 17 and divides the sound-insulating particles inside the second filling layer 19 to prevent them from agglomerating and causing a decrease in local sound absorption. At the same time, the rear end of the second filling layer 19 contacts the front end of the silicone layer 12, which further makes the sound-insulating particles inside the second filling layer 19 fit more closely to the rear end of the second sound-absorbing panel 17, thus enhancing the sound absorption effect.

[0033] The implementation principle of the fireproof and environmentally friendly polyester fiber sound-absorbing board in this application embodiment is as follows: First, the positioning plate 6 connected to the connecting frame 8 is installed to the designated area by connecting bolts 7, and the spacing between the positioning plates 6 conforms to the spacing between the insertion cavities 3. Next, the insertion cavity 3 is aligned with the connecting frame 8 and the insertion is completed. After the insertion is completed, the outer wall of the connecting frame 8 abuts against the outer wall of the second limiting protrusion 9, thereby making the connecting frame 8 self-limited with the first sound-absorbing plate 1 and the sealing frame 2. After the second flame-retardant plate 11 is installed inside the sealing frame 2, the first flame-retardant plate 10 will be inserted into the male hook and loop fastener 13, the female hook and loop fastener 14 and the first filling layer 15, and will contact one end of the silicone layer 12. In this way, the first filling layer 15 is filled with flame-retardant particles, which can effectively retard flames when an open flame is present, and work with the first flame-retardant plate 10 to further block the spread of open flames. Finally, the second sound-absorbing panel 17, the sound-insulating coating 18, and the second filling layer 19 work together to form a triple sound-absorbing structure. The reinforcing block 20 strengthens the second sound-absorbing panel 17 and divides the sound-insulating particles inside the second filling layer 19 to prevent them from agglomerating and causing a decrease in local sound absorption. At the same time, the rear end of the second filling layer 19 contacts the front end of the silicone layer 12, which further makes the sound-insulating particles inside the second filling layer 19 fit more closely to the rear end of the second sound-absorbing panel 17, thus enhancing the sound absorption effect. In this way, a fireproof and environmentally friendly polyester fiber sound-absorbing panel is completed.
