Preparation method and application of sound-absorbing foamed ceramic
The invention provides a preparation method and application of sound-absorbing foamed ceramic, and belongs to the technical field of buildings. The sound-absorbing foamed ceramic has the characteristics of light weight, high strength, small and uniform aperture, low cost and the like, the volume density is 1.19-2.07 g/cm < 3 >, the compressive strength is 3.5-10 MPa, the aperture size is 2-450 microns, the apparent porosity is 25-60%, the 1h water absorption rate is 10-50%, the use requirements of the sound-absorbing foamed ceramic are met, and the sound-absorbing foamed ceramic has a relatively good pore structure. According to the sound-absorbing foamed ceramic, 90% or above of the raw materials are industrial solid waste and building solid waste, the preparation cost is low, the sound-absorbing foamed ceramic is excellent in performance and can be used for manufacturing high-performance ceramic sound-insulating bricks, and an effective way is provided for resource utilization of the industrial solid waste and the building solid waste.
本发明提供了一种吸音泡沫陶瓷的制备方法和应用，属于建筑技术领域。本发明的吸音泡沫陶瓷具有轻质、高强、孔径小且均匀、低成本等特点，体积密度为1.19～2.07g/cm3，抗压强度为3.5～10MPa，孔径大小为2～450μm，显气孔率为25％～60％，1h吸水率为10％～50％，满足吸音泡沫陶瓷的使用要求，且拥有较好的气孔结构。本发明的吸音泡沫陶瓷中，90％以上的原料为工业固体固废和建筑固废，制备成本低，本发明的吸音泡沫陶瓷性能优异，可制作高性能陶瓷隔音砖，为工业固废和建筑废料的资源化利用提供了有效途径。
