Ceramic water reducer and preparation method thereof
The invention provides a ceramic water reducer and a preparation method thereof, the ceramic water reducer comprises the following components: greater than or equal to 14% of Na2O and greater than or equal to 26% of SiO2, the preparation method comprises the following steps: step (a), at a first preset temperature, silicon slag generated in a zirconium oxychloride production process reacts with alkali liquor for a first preset time to obtain a clear solution, and the mass ratio of the silicon slag to the alkali liquor is 1: 2-1: 5; and step (b), at a second preset temperature, the clear solution concentrated to the preset concentration reacts with quartz for a second preset time, filtering is performed to obtain the ceramic water reducer, and the mass ratio of the clear solution to the quartz is 2: 1-6: 1. The silicon slag and the waste alkali liquid generated in the zirconium oxychloride production process are adopted as raw materials, so that resource utilization of waste liquid and waste residues is realized, and the three-waste treatment cost is saved.
本发明提供了一种陶瓷减水剂及其制备方法，该陶瓷减水剂的成分为：Na2O≥14％，SiO2≥26％，其制备方法包括：步骤(a)，在第一预设温度下，将氧氯化锆生产过程产生的硅渣与碱液进行反应第一预设时间后，得到澄清溶液，其中，硅渣与碱液的质量比为：1:2‑1:5；步骤(b)，在第二预设温度下，将浓缩到预设浓度后的澄清溶液与石英进行反应第二预设时间后，进行过滤以得到陶瓷减水剂，其中，澄清溶液与石英的质量比为：2:1‑6:1。本发明通过采用氧氯化锆生产过程产生的硅渣与废碱液为原料，实现废液、废渣的资源化利用，从而节约“三废”处理成本。
