Low-cost porous ceramic sound absorbing material and preparation process thereof
The invention relates to a low-cost porous ceramic sound absorbing material and a preparation process thereof. The ceramic sound absorbing material is prepared from the following raw materials in percentage by weight: 23-28 percent of combination-process red mud, 23-28 percent of steel slags, 13-18 percent of coal gangue, 8-12 percent of carbide slag, 8-12 percent of boiler slags, 3-8 percent of quartz sand and 8-12 percent of a 10% sodium hydroxide solution. By taking the metallurgical industrial waste red mud and steel slags as main raw materials, the sound absorbing material disclosed by the invention can be used for solving the problem of noise pollution of subways, urban roads, expressways and railways.
