Impedance composite sound absorption and insulation board and preparation method thereof
The invention relates to the technical field of sound absorption and insulation board materials, in particular to an impedance composite sound absorption and insulation board and a preparation method thereof. The impedance composite sound absorption and insulation board is composed of a resistive back board, a resistant panel and a resistant cavity. The impedance composite sound absorption and insulation board is good in weather resistance and suitable for sound absorption and insulation and noise reduction in various occasions. The sound absorption and insulation board has a reactive noise elimination function and has an excellent noise reduction effect on low-frequency-band noise. The sound insulation board does not contain sound absorption fiber products such as rock wool and glass wool, and the resistive back board takes foaming cement as a base material, so that the materials are wide in source, the manufacturing process is simple, and the cost is low. Compared with a traditional metal sound insulation board, the cement sound insulation board is excellent in sound insulation performance. Meanwhile, the sound insulation amount of the sound insulation board can be increased under the condition that the weight of the sound insulation board is not increased by adjusting the thickness of the resistant cavity. The resistive back plate and the resistant panel are resistant to wind, rain and sunlight, good in weather resistance and suitable for noise reduction in various occasions. Good market popularization prospects are realized.
本发明涉及吸、隔声板材料技术领域，尤其涉及一种阻抗复合吸隔声板及其制备方法。所述阻抗复合吸隔声板由阻性背板、抗性面板以及抗性空腔组成。所述阻抗复合吸隔声板耐候性能好，适用于各种场合的吸隔声降噪。所述吸隔声板，带抗性消声功能，对低频段噪声降噪效果优良。所述隔声板不含岩棉、玻璃棉等吸声纤维制品，阻性背板以发泡水泥为基材，取材广泛，制作工艺简单，成本低廉。相比传统金属隔声板、水泥隔声板隔声性能优越。同时可通过调整抗性空腔厚度实现不增加隔声板重量的情况下，增加隔声板的隔声量。所述阻性背板、抗性面板不怕风吹、雨淋、日晒，耐候性能好，适用于各种场合的降噪。拥有很好的市场推广前景。
