Tailing sand filling gelling auxiliary material and preparation method thereof
The invention discloses a tailing sand filling gelling auxiliary material and a preparation method thereof. The tailing sand filling gelling auxiliary material comprises the following main components: 4-50 parts of sulfonated oil, 30-35 parts of a silane coupling agent, 8-10 parts of anionic polyacrylamide, 6-10 parts of an alkaline activator, 3-5 parts of an environment-friendly sulfate activator, 0.3-0.8 part of a dispersant, 1-2 parts of an anionic surfactant and 100 parts of water. According to the tailing sand filling gelling auxiliary material disclosed by the invention, the tailing sand is gelling by using small doses of solid wastes such as the auxiliary sludge, the water granulated slag, the steel slag, the desulfurized fly ash and the fly ash, so that the strength of filling slurry can reach an expected target; when auxiliary cement gel tailing sand is used for filling, the cement-sand ratio can be effectively reduced, the production cost is saved, and the filling body doped with the filling gel auxiliary material has higher strength and better durability. The tailing sand filling and gelling auxiliary material is low in production cost, excellent in gelling effect, safe and environment-friendly in material and simple in preparation process, is a novel green and environment-friendly gelling material, and is wide in application prospect.
本发明公开了一种尾矿砂充填胶凝辅助材料及其制备方法，其主要成分包括：磺化油4～50份、硅烷类偶联剂30～35份、阴离子聚丙烯酰胺8～10份、碱性激发剂6～10份、环保硫酸盐激发剂3～5份、分散剂0.3～0.8份、阴离子型表面活性剂1～2份、水100份；本发明所述尾矿砂充填胶凝辅助材料，以小剂量辅助污泥、水渣、钢渣、脱硫灰、粉煤灰等固体废弃物胶凝尾矿砂，即可使充填料浆强度达到预期目标；辅助水泥胶凝尾矿砂进行充填时，宜可有效降低灰砂比，节约生产成本，掺有充填胶凝辅助材料的充填体，具有更高的强度与更好的耐久性。本发明所述尾矿砂充填胶凝辅助材料，生产成本低、胶凝效果优良、材料安全环保、制备工艺简单，为一种新型绿色环保胶凝材料，应用前景广阔。
