Step hole foaming ceramic based on sulfur-containing tailings and preparation method thereof
The invention relates to the technical field of porous ceramic preparation, in particular to sulfur-containing tailing-based stepped hole foamed ceramic and a preparation method thereof, and the raw materials comprise 20-60 parts of sulfur-containing tailings, 30-70 parts of coal-series industrial solid waste, 3-15 parts of a fluxing agent, 2-8 parts of a foam stabilizer, 0.05-0.30 part of a foaming agent and 0.05-0.50 part of triethanolamine. The preparation method comprises the following steps: sequentially adding the raw materials into a ceramic ball milling tank, carrying out wet mixing to prepare uniform slurry, drying and crushing the slurry to prepare powder, filling a square fire-resistant sagger with the powder, and carrying out high-temperature foaming, cooling and cutting to prepare the foamed ceramic of which the pore diameter is gradually reduced in the height direction. The stepped hole foamed ceramic prepared by the invention not only has higher mechanical property, but also has good thermal insulation property, and the preparation method not only solves the problem that the mechanical property and the thermal insulation property of the foamed ceramic are difficult to balance, but also realizes high value-added utilization of industrial solid wastes.
本发明涉及多孔陶瓷制备技术领域，具体涉及一种基于含硫尾矿的梯级孔发泡陶瓷及其制备方法，原材料包括：含硫尾矿20～60份、煤系工业固废30～70份、助熔剂3～15份，稳泡剂2～8份、发泡剂0.05～0.30份、三乙醇胺0.05～0.50份。将上述原材料依次加入陶瓷球磨罐中，经湿法混合制成均匀的料浆，料浆经干燥、破碎制成粉体，并填装在方形耐火匣钵内，随后经高温发泡、冷却切割，制备成孔径沿高度方向梯级减小的发泡陶瓷。本发明制得的梯级孔发泡陶瓷不仅具有较高的力学性能，还具有良好的保温性能，这一制备方法不仅解决了发泡陶瓷力学性能和保温性能难以平衡的问题，也实现了工业固体废弃物的高附加值利用。
