Ceramsite acoustic board for metal sound barrier and preparation method and application of ceramsite acoustic board
The invention discloses a ceramsite acoustic board for a metal sound barrier and a preparation method and application of the ceramsite acoustic board. The ceramsite acoustic board is prepared from the following raw materials in percentage by weight: 50%-90% of ceramsite, 10%-50% of a cementing material, 0%-5% of an additive and 0%-1% of a fiber material, wherein the ceramsite comprises one or a combination of several of No.1 ceramsite with the particle size of 1-3mm, No.2 ceramsite with the particle size of 3-5mm and No.3 ceramsite with the particle size of 5-10mm. The raw materials are fully stirred and mixed according to the weight ratio, oscillated, pressurized, cured and demolded to form the ceramsite acoustic board with the thickness of 30-80 mm, and the side, facing a sound source, of the acoustic board is a plane or a concave-convex surface. After the sound barrier metal shell is placed, a 30-100 mm air layer is formed on the back of the sound absorption material. Continuous pore structures with different sizes exist among the ceramsites in the ceramsite acoustic board, so that the acoustic board has a good acoustic absorption coefficient in a wide frequency band.
本发明公开了一种金属声屏障陶粒吸声板及其制备方法与应用，陶粒吸声板由如下重量百分比原料组成：陶粒50%~90%、胶凝材料10%~50%、外加剂0%~5%、纤维材料0%~1%；所述陶粒中：包括粒径1~3毫米的一号陶粒、粒径3~5毫米的二号陶粒、粒径5~10毫米的三号陶粒中的一种或几种组合。原料按重量配比充分搅拌混合、振荡加压、养护、脱模后形成厚度30~80毫米的陶粒吸声板，吸声板面向声源一侧为平面或凹凸面。放入声屏障金属外壳后，吸声材料背部形成30~100毫米空气层。本发明的陶粒吸声板内部陶粒之间存在尺寸不同的、连续的孔隙结构，使得吸声板在较宽频带内均有良好的吸声系数。
