Sound absorbing material and preparation method thereof
The invention discloses a sound absorbing material and a preparation method thereof. The sound absorbing material is composed of an upper sound absorbing layer, a lower sound absorbing layer and a middle sound insulation layer, and the sound absorbing layers are mineral wool; the sound insulation layer is prepared from the following raw materials in parts by weight: 20-30 parts of sunflower rhizome powder, 40-60 parts of gypsum, 0.2-0.5 part of benzoic acid and 50-70 parts of water. The sound absorbing material adopts biomass material sunflower rhizomes as a raw material, has environmental friendliness, plays a role in waste utilization, and saves resources. Due to the characteristics of the three-layer structure, the sound absorbing material has good sound absorption performance and a good sound insulation effect, the mineral wool is adopted as the sound absorbing layers, and therefore the sound absorbing material has good flame retardant property and can be applied to a high-temperature environment. In addition, the mineral wool has good chemical stability and corrosion resistance, and the service life of the prepared sound absorbing material is greatly prolonged.
本发明公开了一种吸音材料及其制备方法，吸音材料由上下两层吸音层和中间隔音层组成，所述吸音层为矿渣棉；所述隔音层由以下重量份原料组成：向日葵根茎碎末20‑30份、石膏40‑60份、苯甲酸0.2‑0.5份、水50‑70份。本发明公开的吸音材料采用生物质材料向日葵根茎作为原料，具有环保性，并且起到了废物利用的作用，节约资源。三层结构的特点使其具有良好的吸音性能的同时，还具有好的隔音效果，采用矿渣棉作为吸音层，使得本发明的吸音材料具有很好的阻燃性能，可以应用于高温环境。此外，矿渣棉具有很好的化学稳定性和耐腐蚀性，大大增强了所制得吸音材料的使用寿命。
