Multilayer structure ceramsite acoustic board for sound barrier and preparation method of multilayer structure ceramsite acoustic board
The invention discloses a multilayer structure ceramsite acoustic board for a sound barrier and a preparation method of the multilayer structure ceramsite acoustic board. Each layer of ceramsite acoustic board is prepared from the following raw materials in percentage by weight: 40-92% of ceramsite aggregate and 8-60% of cementing material, each layer of ceramsite sound absorption plate is one of a No.1 ceramsite plate, a No.2 ceramsite plate, a No.3 ceramsite plate or a No.4 ceramsite plate; ceramsite aggregate of the No.1 ceramsite plate is first ceramsite with the particle size being smaller than 2 mm, ceramsite aggregate of the No.2 ceramsite plate is second ceramsite with the particle size being 25 mm, ceramsite aggregate of the No.3 ceramsite plate is third ceramsite with the particle size being larger than 5 mm, and ceramsite aggregate of the No.4 ceramsite plate is fourth ceramsite mixed with different particle sizes; in the fourth ceramsite, the proportion of the first ceramsite is 0-90%, the proportion of the second ceramsite is 0-90%, and the proportion of the third ceramsite is 0-90%. By utilizing a large number of porous structures in the ceramsite acoustic board with the multi-layer structure, good acoustic absorption performance is realized, and excellent mechanical properties are realized by matching with a cementing material.
本发明公开了一种用于声屏障的多层结构陶粒吸声板及其制备方法，各层陶粒吸声板分别由如下重量百分比原料组成：陶粒骨料40%～92%、胶凝材料8%～60%；各层陶粒吸声板分别为一号陶粒板、二号陶粒板、三号陶粒板或四号陶粒板中的一种；一号陶粒板的陶粒骨料为粒径小于2毫米一号陶粒，二号陶粒板的陶粒骨料为粒径2~5毫米二号陶粒，三号陶粒板的陶粒骨料为粒径大于5毫米三号陶粒，四号陶粒板的陶粒骨料为不同粒径混合的四号陶粒；四号陶粒中：一号陶粒占比0%～90%，二号陶粒占比0%～90%，三号陶粒占比0%～90%。本发明利用多层结构陶粒吸声板内部大量多孔结构，实现了良好吸声性能，通过与胶凝材料配合，实现了优良力学性能。
