Description

Technical Field

[0001] The utility model relates to the technical field related to sound-absorbing panels, and in particular to a fire-resistant and flame-retardant sound-absorbing panel. Background Art

[0002] Acoustic panels are an ideal sound-absorbing decorative material. They offer advantages such as sound absorption, environmental friendliness, flame retardancy, heat insulation, thermal insulation, moisture resistance, mildew resistance, easy dust removal, easy cutting, parquetry adaptability, simple construction, excellent stability, strong impact resistance, high independence, and a high cost-effectiveness ratio. Available in a wide variety of colors, they can meet the needs of various styles and levels of sound-absorbing decoration. They are widely used in acoustically demanding venues such as theaters, concert halls, movie theaters, recording studios, studios, monitoring rooms, conference rooms, gymnasiums, exhibition halls, dance halls, KTV rooms, home theaters, factories, quiet rooms, courtrooms, lecture halls, interrogation rooms, and textile mills, as well as factories with excessive noise levels and large public buildings for sound-absorbing wall panels and ceiling panels.

[0003] After extensive searching, it was found that the Chinese patent publication number is CN213935636U, which discloses a polyester fiber sound-absorbing panel that is easy to assemble, including a first sound-absorbing panel, a second sound-absorbing panel is arranged on the outside of the first sound-absorbing panel, and push-pull rods are arranged on the top and bottom of the second sound-absorbing panel. The push-pull rod is fixedly connected to a guide rod on the side close to the second sound-absorbing panel. In the utility model, through the cooperation of the clamping plate and the locking block, the user drives the guide rod and the clamping plate to squeeze the first spring and the second spring on the outside of the guide rod through the push-pull rod. The user puts the first sound-absorbing panel into the second sound-absorbing panel, releases the push-pull rod, and uses the elastic force of the first spring and the second spring to return the guide rod to its position. The guide rod drives the locking block to be clamped into the first sound-absorbing panel through the clamping plate. The user uses a tool to fix the locking screw in the splint and the first sound-absorbing panel, and the assembly is completed, which solves the problem that the existing polyester fiber sound-absorbing panels are not convenient to assemble and take a long time to assemble.

[0004] In summary, due to the material of the existing sound-absorbing panels, their fire retardant performance is generally poor, and when a fire occurs, they cannot effectively retard the fire.

[0005] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a fire-retardant sound-absorbing panel to make it more valuable for industrial use. Utility Model Content
