Magnesium-rich nickel slag geopolymer porous material and preparation method thereof
The invention discloses a magnesium-rich nickel slag geopolymer porous material and a preparation method thereof. The magnesium-rich nickel slag geopolymer porous material comprises 500-900 parts of magnesium-rich nickel slag, 100-500 parts of fly ash, 100-400 parts of an exciting agent, 200-400 parts of water, 1-100 parts of a foaming agent and 1-30 parts of a foam stabilizer. The exciting agent comprises Na2SiO3, NaOH and phosphoric acid, and when the exciting agent is NaOH, the part of the exciting agent in the total raw materials is the part of pure NaOH; when the exciting agent comprises Na2SiO3 and NaOH, the part of the exciting agent in the total raw materials is the sum of the parts of pure Na2SiO3 and NaOH; when the exciting agent comprises phosphoric acid, the part of phosphoric acid in the total raw materials is the part of pure phosphoric acid. According to the invention, the foaming agent and the foam stabilizer are used for preparing the porous material, and the method has the advantages of simple processing technology, environmental protection, low energy consumption and low cost, and can show large porosity and good compressive strength.
本发明公开了一种富镁镍渣地质聚合物多孔材料及制备方法，包括：富镁镍渣500‑900份，粉煤灰100‑500份，激发剂100‑400份，水200‑400份，发泡剂1‑100份，稳泡剂1‑30份；所述激发剂包括Na2SiO3、NaOH及磷酸，当所述激发剂为NaOH，其中激发剂占总原料的份数为纯NaOH所占份数；当所述激发剂包括Na2SiO3和NaOH，其占总原料的份数为纯Na2SiO3和NaOH相加所占份数；当所述激发剂包括磷酸，其占总原料的份数为纯磷酸所占份数。根据本发明，利用发泡剂和稳泡剂制备多孔材料，且加工工艺简单、绿色环保、能耗低、成本低的方法，可显示出较大的孔隙率和较好的抗压强度。
