A2-grade fireproof material prepared from brucite tailings and preparation method of A2-grade fireproof material
The invention belongs to the field of fireproof material preparation, and discloses an A2-grade fireproof material prepared from brucite tailings and a method thereof, and the A2-grade fireproof material is prepared from the following raw materials in percentage by mass: 80-90% of brucite tailings, 5-15% of aqueous emulsion, 5-10% of deionized water and 2-5% of inorganic fiber. The method comprises the following main process steps: (1) coarsely crushing brucite tailings of which the main components are magnesium hydroxide, silicon dioxide and calcium carbonate into granules of 5-20mm; (2) spraying, dedusting and drying the granules; (3) adopting a Taihe three-section ore color sorter to select brucite granules with the magnesium oxide content of more than 20% as a raw material; (4) further grinding the granules selected in the step (3) to 100-325 meshes; and (5) uniformly mixing the ground material with a water-based emulsion, inorganic fibers and deionized water to prepare the A2-grade fireproof material. According to the invention, the product with high-end economic value is prepared from waste resources, and the problem of land occupation caused by stacking of tailings and the problem of dust secondary pollution caused by wind blowing when the tailings are stacked anywhere are solved.
本发明属于防火料制备领域，公开了利用水镁石尾矿制备的A2级防火料及其方法，所用原料按质量百分比计，水镁石尾矿料80％‑90％，水性乳液5％‑15％，去离子水5％‑10％，无机纤维2％‑5％。主要工艺步骤如下：(1)利用主要成分为氢氧化镁、二氧化硅、碳酸钙的水镁石尾矿，粗破为5‑20mm粒料；(2)粒料喷淋除尘、干燥；(3)采用泰和三段式矿石色选机挑选氧化镁含量大于20％的水镁石粒料做原料；(4)将步骤(3)中挑选的粒料进一步研磨至100～325目；(5)将磨好的料与水性乳液、无机纤维、去离子水混合均匀，制得A2级防火料。本发明不仅利用废弃资源制备了具有高端经济价值的产品，而且解决了尾矿堆放占用土地的问题和尾矿随处堆放刮风时引起的粉尘二次污染问题。
