Solid-waste-based foamed ceramic sound absorption and insulation material and preparation method thereof
The invention belongs to the technical field of foamed ceramic production, and provides a preparation method of a solid-waste-based foamed ceramic sound-absorbing and sound-insulating material. The preparation method comprises the following steps: crushing waste stone, and sieving to obtain a base material; uniformly mixing the base material, the foaming agent and the pore forming agent to obtain a mixture; and pressing the mixture into a green body, and sintering to obtain the foamed ceramic sound absorption and insulation material. The mass of the foaming agent is 0.5%-2% of that of the base material; the mass of the pore-forming agent is 2-10% of that of the base material; the waste stone is at least one of granite and marble; the foaming agent is at least one of silicon carbide, carbonate, manganese oxide and iron oxide; the pore-forming agent is at least one of starch, rice husk, sawdust and polymethacrylate. Through the synergistic matching effect of the foaming agent and the pore-forming agent, a three-dimensional communicating pore structure with open pore and closed pore forms is realized. The prepared material is good in sound insulation and sound absorption effects and wide in application range; meanwhile, the preparation method is simple, solid waste is consumed, the cost is low, and application and popularization are facilitated.
本发明属于发泡陶瓷生产技术领域，提供了一种固废基发泡陶瓷吸音隔声材料的制备方法：将废石料粉碎、过筛得到基料；基料和发泡剂、造孔剂混合均匀，得到混合料；混合料压制成坯体，然后烧结，得到发泡陶瓷吸音隔声材料。发泡剂的质量为基料的0.5%‑2%；造孔剂的质量为基料的2%‑10%；所述废石料为花岗岩和大理石中的至少一种；发泡剂为碳化硅、碳酸盐、氧化锰和氧化铁中的至少一种；造孔剂为淀粉、稻壳、锯末和聚甲基丙烯酸酯中的至少一种。本发明通过发泡剂和造孔剂的协同匹配作用，实现兼具开孔和闭孔形态的三维连通孔结构。制备的材料隔音和吸音效果好，使用范围广；同时，制备方法简单，消纳固废、成本低，有利于推广应用。
