Solid waste foamed ceramic material as well as preparation method and application thereof
The invention belongs to the technical field of foamed ceramics, and provides a solid waste foamed ceramic material as well as a preparation method and application thereof. The solid waste foamed ceramic material is prepared from the following raw materials in parts by mass: 25-35 parts of coal gasification slag, 30-40 parts of coal gangue, 5-15 parts of sludge, 3-5 parts of red mud, 2-4 parts of a fluxing agent, 0.5-1.0 part of a foaming agent and 0.3-0.5 part of a foam stabilizer. The solid waste raw material, the fluxing agent and the foaming agent are reasonably selected, the proportion of the raw materials is reasonably controlled, and a specific roasting process is combined, so that the melt viscosity is matched with the pressure generated by pores, and the foamed ceramic material with a good pore structure, uniform pores, low volume density and heat conductivity coefficient and good mechanical properties is obtained; and the roasting temperature is obviously reduced, and the method has important significance on energy conservation and emission reduction.
本发明属于发泡陶瓷技术领域，提供了一种固废发泡陶瓷材料及其制备方法和应用。本发明的固废发泡陶瓷材料包含如下质量份的制备原料：煤气化渣25～35份、煤矸石30～40份、淤泥5～15份、赤泥3～5份、助熔剂2～4份、发泡剂0.5～1.0份、稳泡剂0.3～0.5份。本发明通过合理选择固废原料、助熔剂和发泡剂，合理控制各原料的比例，结合特定的焙烧工艺，使得熔体黏度与气孔产生的压力相匹配，得到具有良好孔结构，孔隙均匀，体积密度和导热系数低，力学性能良好的发泡陶瓷材料，且焙烧温度显著降低，对于节能减排具有重要意义。
