Foamed porous ultrahigh-water material and preparation method thereof
The invention relates to the technical field of filling materials, in particular to a foamed porous ultrahigh-water material and a preparation method thereof. The foamed porous ultrahigh-water material is prepared from the following raw materials: cement, alkali metal salt, a water reducing agent and a dispersing agent in a mass ratio of (95-98): (0.1-1): (0.5-2): (0.1-2), and a foaming agent and a foaming agent A in a mass ratio of (0.1-2): (0.5-5), the raw materials for forming the material B comprise gypsum, lime and aggregate in a mass ratio of (10-50): (10-50): (10-40), and a foaming agent B, a dispersing agent and an accelerator in a mass ratio of (0.1-2): (0.5-10): (0.1-5). The foamed porous ultrahigh-water-content material has a honeycomb porous structure, is foamed on the whole, can adsorb soluble salt and gas, is high in pressure resistance and can be effectively used for filling in the coal mining process.
本发明涉及填充材料技术领域，具体而言，涉及泡沫状多孔超高水材料及其制备方法。泡沫状多孔超高水材料的原料质量比为(95‑98)：(0.1‑1)：(0.5‑2)：(0.1‑2)的水泥、碱金属盐、减水剂和分散剂和质量比为(0.1‑2)：(0.5‑5)的起泡剂和造泡剂A；形成乙料的原料包括质量比为(10‑50)：(10‑50)：(10‑40)的石膏、石灰和骨料和质量比为(0.1‑2)：(0.5‑10)：(0.1‑5)的造泡剂B、分散剂和速凝剂。该泡沫状多孔超高水材料具有蜂窝状的多孔结构，其整体呈现为泡沫状，能吸附可溶性盐和气体，且该超高水材料抗压能力强，可以有效用于煤矿开采过程中的填充。
