Cement admixture for full tailing filling, preparation method and filling slurry
The invention relates to the field of mine tailing filling, and particularly discloses a cement admixture for full tailing filling, a preparation method and filling slurry. The admixture is prepared from the following raw materials in parts by weight: ammonium persulfate, sodium methallyl sulfonate, hydroxypropyl methyl cellulose, calcium formate, tetraethyl orthosilicate, polyoxyethylene ether, methyl sodium tartrate, polyacrylamide, trimethyl ammonium chloride, sodium dodecyl benzene sulfonate, sodium phosphite and water; the preparation method comprises the following steps: mixing and stirring ammonium persulfate, sodium methallyl sulfonate and water, adding hydroxypropyl methyl cellulose in the process, then adding calcium formate, mixing, adding tetraethyl orthosilicate, polyoxyethylene ether and sodium potassium tartrate tetrahydrate, mixing, finally adding polyacrylamide, trimethyl ammonium chloride, sodium dodecyl benzene sulfonate and sodium phosphite, uniformly mixing, and drying to obtain a finished product. Preparing a finished product additive; the filler is used for preparing filling slurry; the full-tailing filling body has the advantages of being good in mechanical strength and good in slurry conveying performance.
本申请涉及矿山尾砂充填领域，具体公开了一种全尾砂充填用水泥外加剂、制备方法及充填料浆；所述外加剂由包含以下重量份的原料制成：过硫酸铵、甲基丙烯磺酸钠、羟丙甲基纤维素、甲酸钙、正硅酸四乙酯、聚氧乙烯醚、酒石酸甲钠、聚丙烯酰胺、三甲基氯化铵、十二烷基苯磺酸钠、亚磷酸钠、水；其制备方法为：过硫酸铵、甲基丙烯磺酸钠、水混合搅拌，过程中添加羟丙甲基纤维素，然后添加甲酸钙混合，再添加正硅酸四乙酯、聚氧乙烯醚、酒石酸钾钠混合，最后添加聚丙烯酰胺、三甲基氯化铵、十二烷基苯磺酸钠、亚磷酸钠混合均匀，干燥后，制得成品外加剂；用于制备充填料浆；具有使全尾砂充填体具有较好机械强度以及较好的料浆输送性的优点。
