Cement-based fly ash floating bead sound absorption material and preparation method thereof
The invention belongs to the technical field of sound absorption materials, and relates to a cement-based fly ash floating bead sound absorption material and a preparation method thereof. The cement-based fly ash floating bead sound absorption material is provided on the first aspect and comprises a mixture of fly ash floating beads, cement and a water reducing agent, and the mass ratio of the fly ash floating beads to the cement to the water reducing agent is (70-110): 100: 0.6. The sound absorption coefficient of the cement-based fly ash floating bead sound absorption material provided by the invention is higher than that of a common porous sound absorption material especially at a low-frequency band, the cement-based fly ash floating bead sound absorption material can be expected to be used for various sound absorption structures and indoor and outdoor spaces needing acoustic design, and accumulation of byproducts and pollution to the environment can be effectively reduced; the method conforms to the national development strategy of energy conservation and emission reduction, the production amount of traditional cement-based sound absorption material aggregates such as rubber particles can be reduced, and resources are saved.
本申请属于吸声材料技术领域，涉及一种水泥基粉煤灰漂珠吸声材料以及制备方法。其中，本申请第一方面提供了一种水泥基粉煤灰漂珠吸声材料，包括粉煤灰漂珠、水泥和减水剂的混合物，且所述粉煤灰漂珠：水泥：减水剂的质量比为70～110:100:0.6。本申请提供的水泥基粉煤灰漂珠吸声材料尤其在低频段处的吸声系数高于一般多孔吸声材料，可期待用于各类吸声构造和需要声学设计的室内外空间，本申请可以有效减少这些副产品堆积和对环境的污染，符合国家节能减排的发展策略，且也能减少传统水泥基吸声材料集料如橡胶颗粒等的生产量，节约资源。
