Environment-friendly noise reduction barrier and surface treatment process thereof
The invention discloses an environment-friendly noise reduction barrier and a surface treatment process thereof, belonging to the field of sound insulation materials. According to the environment-friendly noise reduction barrier and the surface treatment process thereof, noise reduction nets which are distributed in a staggered and overlapped mode are embedded in a sound absorption material; when noise is generated at a high position, the noise enters a partition ball along a sound guide rod, and in an approximately vacuum environment of the partition ball , sound is effectively prevented from being transmitted to the other side, so compared with the prior art, environment protection and noise reduction effects are remarkably improved; and in addition, in cooperation with pretreatment of the noise reduction nets, porous inner sound absorption layers with small density are formed in the partition ball, so the sound insulation effect of the partition ball from inside to outside is remarkably improved, noise transmitted into the partition ball is effectively prevented from being reversely and continuously transmitted outwards through the inner wall of the partition ball along an inner guide rod, and then, noise partition effect is better.
本发明公开了一种环保型降噪屏障及其表面处理工艺，属于隔音材料领域，一种环保型降噪屏障及其表面处理工艺，通过在吸音材料内嵌入错位交叠分布的消音网，在高处产生噪音时，噪音沿着导音杆进入到隔断球内，在其内接近真空的环境中，有效阻隔声音向另一侧的传递，相较于现有技术，显著提高环保降噪的效果，另外配合对消音网的预处理，使隔断球内形成多孔且密度较小的内吸音层，显著提高隔断球由内向外的隔音效果，有效避免传递到隔断球内的噪音逆向沿着内导杆通过隔断球内壁向外继续传递，进而使对噪音的隔断效果更好。
