Foamed ceramic based on graphite tailings and preparation method of foamed ceramic
The invention discloses foamed ceramic based on graphite tailings. The foamed ceramic comprises the following components in percentage by mass: 45-70% of graphite tailings, 10-15% of quartz, 5-15% ofbauxite and 15-25% of feldspar. Meanwhile, 0.1 to 0.5 percent of silicon carbide is added. Graphite tailings, quartz, bauxite, feldspar and silicon carbide are sequentially subjected to ball-milling mixing, water adding granulation, blank preparation, aging, pressing, firing and other processes to prepare the foamed ceramic. In combination with formula design and process optimization, the pore structure, distribution and size of the obtained foamed ceramic can be further optimized while high-additive-amount application of the graphite tailings in the foamed ceramic is achieved, the heat conductivity coefficient of the foamed ceramic is remarkably reduced, and the heat insulation performance of the foamed ceramic is improved. The foamed ceramic has the advantages of light weight, high strength, good thermal insulation and fireproof performance and the like, can realize high-added-value application of the graphite tailings, and has important economic and environmental benefits.
本发明公开了一种基于石墨尾矿的发泡陶瓷，各组分及其所占质量百分比包括：石墨尾矿45～70％，石英10～15％，铝矾土5～15％，长石15～25％；同时外加0.1～0.5％的碳化硅；通过将石墨尾矿、石英、铝矾土、长石、碳化硅依次进行球磨混料、加水造粒、制备坯料、陈腐、压制、烧制等工艺制备而成。本发明结合配方设计和工艺优化，在实现石墨尾矿在发泡陶瓷中高添加量应用的同时，可进一步优化所得发泡陶瓷的气孔结构、分布和尺寸，显著降低其导热系数，改善其隔热保温性能。本发明所得发泡陶瓷具有质量轻、强度高、保温隔热和防火性能好等优点，并可实现石墨尾矿的高附加值应用，具有重要的经济和环境效益。
