On one hand, the invention provides a preparation method of a all-solid-waste-based porous ceramic sound-absorbing material. Solid waste material is crushed and then mixed with a pore-forming material and an additive, and then the all-solid-waste-based porous ceramic sound-absorbing material is obtained through granulation, biscuit forming, sintering and post-processing. Othe other hand, the invention provides the all-solid-waste-based porous ceramic sound-absorbing material prepared by the method. According to the all-solid-waste-based porous ceramic sound-absorbing material provided by the invention, solid waste materials are completely adopted as raw materials, so that the raw materials are wide in source and extremely low in cost, the market selling price of finished products can be controlled to dozens of yuan per ton, in the production process, a large amount of solid waste materials can be consumed, waste is turned into wealth, and the material is green and environment-friendly. In addition, the compressive strength and porosity of the all-solid-waste-based porous ceramic sound-absorbing material prepared by the method can be well coordinated with each other, and the all-solid-waste-based porous ceramic sound-absorbing material has the advantages of good sound-absorbing effect, high mechanical strength, corrosion resistance and good weather resistance, and can be widely applied to the fields of sound absorption and noise reduction of high-speed railways, highway sound barriers and the like.
本发明一方面提供了全固废基多孔陶瓷吸音材料的制备方法，将固废材料粉碎后与造孔材料和添加剂混合，然后经造粒、素坯成型、烧结以及后加工即得；另一方面提供了上述方法制备而得的全固废基多孔陶瓷吸音材料；本发明所提供的全固废基多孔陶瓷吸音材料，由于完全采用固废材料作为原料，不仅原料的来源广泛，且成本极其低廉，使得成品的市场售价能够控制到几十元每吨，并且，在生产过程中，能够消耗大量的固废材料，变废为宝，绿色环保，此外，按本发明的方法制备出的全固废基多孔陶瓷吸音材料的抗压强度与孔隙率能够很好地相互协调，具有吸音效果好、力学强度高、耐腐蚀、耐候性好的优点，可广泛应用于高速铁路和公路声屏障等吸音降噪的领域。
