Coal mine slurry filling thickening agent not prone to caking and preparation method thereof
The invention relates to the technical field of coal mine slurry filling thickening agents, in particular to a coal mine slurry filling thickening agent not prone to caking and a preparation method of the coal mine slurry filling thickening agent. The coal mine slurry filling thickening agent not prone to caking and the preparation method thereof aim at solving the technical problems that in the prior art, gangue particles cannot be well fused with a liquid phase, the viscosity is low, solid particles are prone to caking, and filling construction is not facilitated. According to the technical scheme, the coal mine slurry filling thickening agent difficult to agglomerate is prepared from the following components in parts by weight: 200 to 300 parts of hydroxypropyl methyl cellulose, 350 to 600 parts of polyacrylamide, 300 to 400 parts of polycarboxylic acid dispersing agent, 80 to 150 parts of attapulgite and 30 to 80 parts of nano silicon dioxide. The slurry thickening agent is small in mixing amount and lower in cost, the slurry concentration can be obviously improved, the slurry thickening effect can be obviously observed by naked eyes, the capacity of the slurry for resisting gangue particle precipitation is further improved, long-distance transportation of gangue slurry is facilitated, and filling operation of the slurry is facilitated.
本发明涉及煤矿浆体充填增稠剂技术领域,尤其涉及一种不易结团的煤矿浆体充填增稠剂及其制备方法。技术问题:该不易结团的煤矿浆体充填增稠剂及其制备方法旨在解决现有技术下矸石颗粒无法与液相很好的融合,粘稠度较低,并且固体颗粒容易结团,不利于充填施工的技术问题。技术方案:一种不易结团的煤矿浆体充填增稠剂,包括如下重量份的组分:羟丙基甲基纤维素200~300份、聚丙烯酰胺350~600份、聚羧酸分散剂300~400份、凹凸棒土80~150份、纳米二氧化硅30~80份。本发明掺量小,成本更低,并且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,有利于浆体的充填作业。
