Inorganic foam filling or spraying material as well as preparation method and application thereof
The invention discloses an inorganic foam filling or spraying material as well as a preparation method and application of the inorganic foam filling or spraying material. The inorganic foam material comprises the following components in percentage by mass: 48%-62% of magnesium oxide, 10%-15% of fly ash, 6%-12% of metakaolin, 4-8% of sodium silicate, 8%-16% of phosphate, 3%-4% of a retarder, 3%-7% of an expanding agent and 1%-2% of a foam stabilizer. And grouting the working area through a grouting machine or spraying to the surface of the roadway for multiple times through a pulp shooting machine. The inorganic foam material is a novel single powder inorganic cementing material, can be sprayed and filled, is short in setting time, high in early strength, high in bonding strength and simple and convenient in construction process, and can quickly and effectively solve the problem of filling and sealing of a high-gas mine roadway top-caving area.
本发明公开了一种无机泡沫充填或喷涂材料、其制备方法及应用，该无机泡沫充填或喷涂材料，按照质量百分比计包括如下组分：氧化镁48％‑62％、粉煤灰10％‑15％、偏高岭土6％‑12％、硅酸钠4‑8％、磷酸盐8％‑16％、缓凝剂3％‑4％、膨胀剂3％‑7％、稳泡剂1％‑2％，将混合好的无机泡沫材料与水按水灰比1:1.2‑1.5添加至制浆系统，通过注浆机向工作区域进行注浆或通过喷浆机向巷道表面多次喷洒。该无机泡沫材料为新型单一粉体无机胶结材料，该材料既能喷涂又能充填，实现发泡材料凝结时间快、早期强度高、黏接强度大、施工工艺简便且能够快速有效地解决高瓦斯矿井巷道高冒区充填密闭的难题。
