Description

Technical Field

[0001] The utility model relates to the technical field of sound-absorbing materials, in particular to a formaldehyde-free sound-absorbing material polyester fiber cotton. Background Art

[0002] Sound-absorbing cotton is a highly effective sound-absorbing material made from a variety of synthetic or natural fibers. It resembles foam and has excellent sound absorption properties. Different types of sound-absorbing cotton are made from different materials, resulting in varying sound absorption rates. Its most significant characteristic is its ability to absorb high-frequency sounds, mitigating the resonance of low- and mid-frequency sounds to a certain extent, preventing sound wave reflections and reducing echoes. This significantly reduces noise. Sound-absorbing cotton possesses excellent sound absorption properties, effectively reducing indoor sound rebound and echoes, and improving the indoor acoustic environment.

[0003] The existing device will encounter the following problems when in use: when trying to achieve the required sound-absorbing effect, sound-absorbing cotton of different materials needs to be added together. However, different sound-absorbing cottons need to be glued together, and the formaldehyde in the glue is released into the environment and causes harm to the human body. Secondly, it has no heat insulation effect, resulting in rapid temperature loss and increased energy consumption. Summary of the Invention

[0009] Preferably, the top of the top plate is provided with a wave shape, and the top plate, the shell and the limiting plate are all provided with a polyester fiber cotton material.

[0010] By adopting the above technical solution, the corrugated top plate increases the sound absorption area and improves the sound absorption effect.

[0011] Preferably, the support block is configured to be T-shaped, the material of the support block is configured to be rubber, and an operating groove is provided on the top of the support block.

[0012] By adopting the above technical solution, the support block is driven to rotate 90 degrees in the slot through the operating slot, so that the support block is installed in the top plate, providing supporting strength for the top plate and extending its service life.

[0013] Preferably, the material of the heat insulation layer is set to rock wool.
