Plugging gelling agent for coal mine and preparation method of plugging gelling agent
The invention relates to a plugging gelling agent for coal mine and a preparation method thereof, and relates to the technical field of coal mine plugging materials, the plugging gelling agent for coal mine comprises the following components by weight: 60-75 parts of modified bentonite, 10-25 parts of calcium chloride, 1-10 parts of a filler and 0.5-5 parts of cellulose; the modified bentonite is obtained by mixing, magnetizing and modifying bentonite and sodium silicate; the filler is composed of spherical aluminum powder and hydrotalcite powder. The modified bentonite prepared by mixing, magnetizing and modifying bentonite and sodium silicate is used as a main component, so that not only is the compressive strength of a gel system improved, but also the overall cohesiveness is enhanced; and then the cement is matched with the filler consisting of spherical aluminum powder and hydrotalcite powder, calcium chloride and cellulose for use, so that the viscoelasticity, compactness and stacking property of the slurry can be effectively improved, and the problems of poor compressive strength, poor air leakage stoppage effect and the like of the existing inorganic plugging gelling agent are effectively solved.
本申请涉及一种煤矿用封堵胶凝剂及其制备方法，涉及煤矿封堵材料技术领域，以重量份数计，所述煤矿用封堵胶凝剂包括以下组分：改性膨润土60～75份、氯化钙10～25份、填料1～10份和纤维素0.5～5份；所述改性膨润土是由膨润土和硅酸钠混合磁化改性所得；所述填料是由球状铝粉和水滑石粉组成。本发明采用由膨润土和硅酸钠混合磁化改性所制得的改性膨润土作为主要成分，不仅提升了胶凝体系的抗压强度，而且强化了整体的粘结性；再与由球状铝粉和水滑石粉组成的填料、氯化钙和纤维素配合使用，能够有效提高泥浆的粘弹性、致密性和堆积性，从而有效解决了现有无机封堵胶凝剂存在抗压强度不佳和堵漏风效果差等问题。
