Mining geopolymer foam sealing material and preparation method thereof
The invention discloses a mining geopolymer foam sealing material, which is prepared from the following ingredients in parts by weight: 200 to 500 parts of 52.5 sulphoaluminate cement, 400 to 700 parts of 52.5 R Portland cement, 20 to 200 parts of nanoscale silica fume, 1 to 10 parts of 20mm PP (Propene Polymer) fibers, 1 to 10 parts of reinforcing agents, 0.1 to 10 parts of anti-sagging agents, 1 to 50 parts of foaming agents and 200 to 800 parts of water. Wherein the reinforcing agent is a mixture of a crystal nucleus early strength agent and an alkali-free accelerator, and the mass ratio of the crystal nucleus early strength agent to the alkali-free accelerator is 23: 40; the anti-sagging agent is hydroxypropyl methyl cellulose ether with the viscosity of 200,000. According to the mining geopolymer foam sealing material, by optimizing the material formula, the mechanical property, the bonding property, the durability and other properties of the sealing material are improved. The invention also provides a preparation method of the mining geopolymer foam sealing material.
本发明公开了一种矿用地质聚合物泡沫密闭材料，包括按重量份数计的如下成分：52.5硫铝酸盐水泥200‑500份、52.5R硅酸盐水泥400‑700份、纳米级硅灰20‑200份、20mm PP纤维1‑10份、增强剂1‑10份、抗流挂剂0.1‑10份、发泡剂1‑50份、水200‑800份；其中增强剂为晶核早强剂与无碱速凝剂的混合物，且晶核早强剂与无碱速凝剂的质量比为23:40；抗流挂剂为20万粘度的羟丙基甲基纤维素醚。本发明的矿用地质聚合物泡沫密闭材料，通过优化材料配方，提高其力学性能、粘结性能、耐久性等性能。本发明还提供一种矿用地质聚合物泡沫密闭材料的制备方法。
