Environment-friendly medical sound insulation board
The invention relates to an environment-friendly medical sound insulation board which comprises a base board and a sound insulation layer, the sound insulation layer comprises an inner layer of sound insulation cotton and an outer layer of sound insulation cotton, the sound insulation cotton is made of centrifugal glass fiber materials, fibers in the sound insulation cotton are fluffy and staggered, a large number of tiny holes exist, and the sound insulation cotton is roughly wavy and provided with protruding parts and sunken parts. A hollow air layer is further arranged between the two layers of sound insulation cotton, inert gas is filled in the air layer, the concave portions and the convex portions of the two layers of sound insulation cotton correspond to each other, the large distance between the two layers of sound insulation cotton is 1-2.5 cm, the small distance between the two layers of sound insulation cotton is 0.5-1 cm, the sound insulation index of the protruding portions corresponding to the outer layer of sound insulation cotton is 55-62 dB, and the sound insulation index of the concave portions corresponding to the outer layer of sound insulation cotton can reach 48-53 dB. The sound insulation board is good in sound insulation performance, and the noise influence can be greatly reduced; the durability and the anti-fog effect are good.
本发明涉及一种环保型医用隔音板，包括基板和隔音层，所述隔音层包括有内外两层隔音棉，隔音棉为离心玻璃纤维材料，其内部纤维蓬松交错存在大量微小的孔隙，隔音棉大致呈波浪状具有凸出部与凹陷部，在两层隔音棉之间还具有中空的空气层，空气层内填充惰性气体，两层隔音棉的凹凸部对应，两层隔音棉的较大间距为1‑2.5cm，较小间距为0.5‑1cm，对应外层隔音棉的凸出部位置隔声量为55‑62dB，对应外层隔音棉的凹陷部位置隔声量可达48‑53dB。本发明提供的隔音板隔音性能好，可大大减少噪音影响；且耐久性和防雾效果好。
