Environment-friendly medical sound insulation board

Abstract

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.

Description

Technical field [0001] The invention involves environmental protection technology, especially a kind of environmentally friendly medical sound insulation board. Background technique [0002] Pollution includes the following aspects: water pollution, atmospheric pollution, noise pollution, radioactive pollution, soil pollution, etc.Among them, noise pollution refers to the phenomenon of environmental noise emission standards exceeded by the state, and interfere with the phenomenon of normal work, study, and life of others.Radiation pollution refers to the radioactive substances or rays that cause materials, human, venues, environmental mediums or inside due to human activities. [0003] The sound insulation board is a plate that acts on the sound insulation effect.The sound insulation board is not the sound of all frequencies. The objects have inherent resonance frequencies. The sound close to the resonance frequency of the object, the sound insulation effect of the sound insulati...

AI Technical Summary

Problems solved by technology

When the sound insulation board is in an abnormal or special environment, it is easy to cause the working life of the sound insulation board to be significantly shortened; at the same time, the operating performance of the existing insulation board is also relatively simple, and only a single sound insulation operation can be performed. When the sound insulation board works in a special environment, especially in the medical environment, it cannot better protect against other media
