Coal mine slurry filling thickening agent and preparation method thereof
The invention discloses a coal mine slurry filling thickening agent and a preparation method thereof. The coal mine slurry filling thickening agent comprises the following components in parts by weight: 100-200 parts of hydroxypropyl methyl cellulose, 300-500 parts of polyacrylamide, 200-300 parts of a polycarboxylic acid dispersing agent and 50-100 parts of attapulgite. The thickening agent does not change the original components of the coal mine slurry filling material, and is convenient for large-scale disposal of mine gangue solid waste by slurry with 20-75% of gangue content. The thickening agent can be used as an additive, the mixing amount of the thickening agent does not exceed 3% of the mass of solids in slurry, the mixing amount is small, and the thickening agent is economical. The slurry concentration can be obviously improved, the thickening effect of the slurry can be obviously observed by naked eyes, the gangue particle precipitation resistance of the slurry is further improved, and long-distance transportation of the gangue slurry is facilitated.
本发明公开了一种煤矿浆体充填增稠剂及其制备方法，包括如下重量份数的各组分：羟丙基甲基纤维素100~200份、聚丙烯酰胺300~500份、聚羧酸分散剂200~300份、凹凸棒土50~100份。本发明增稠剂不改变煤矿浆体充填材料原有组份，便于20%~75%矸石含量的浆体大规模处置矿山矸石固废。本发明的增稠剂可作为外加剂使用，其掺量不超过浆体中固体质量的3%，掺量小，较为经济。本发明能够显著提高浆液浓度，肉眼即可明显观察到浆液增稠效果，进而增加了浆液抗矸石颗粒沉淀的能力，便于矸石浆体长距离输送。
