Green inorganic artificial stone taking tungsten tailings as main raw material and preparation method of green inorganic artificial stone
The invention discloses a green inorganic artificial stone with tungsten tailings as a main raw material and a preparation method of the green inorganic artificial stone. The green inorganic artificial stone is prepared from the following raw materials in parts by weight: 20-60 parts of dry tungsten tailings; 3-25 parts of a cementing material; 0 to 1.12 parts of water; 0.32 to 056 parts of a water reducing agent; 1.5 to 4.46 parts of metakaolin; the quartz sand is prepared from the following raw materials in parts by weight: 3.38 to 7.72 parts of quartz coarse sand with the particle size of-40 to 60 meshes; 2.7 to 5.36 parts of quartz medium sand of-60 to + 80 meshes; and 4.29-13.5 parts of quartz fine sand of-80 to + 120 meshes. The tungsten tailings only need to be subjected to filter pressing and do not need to be subjected to high-temperature drying, procedures are reduced, energy is saved, and then the product cost is reduced.
本发明公开了一种以钨尾矿为主要原料的绿色无机人造石及其制备方法，所述绿色无机人造石的制备包括以下重量份的原料：钨尾矿干料20~60份；胶凝材料3~25份；水0~1.12份；减水剂0.32~056份；偏高岭土1.5~4.46份；石英砂10.37~26.58份，其中，所述石英砂包括以下重量份的原料：‑40~+60目石英粗砂3.38~7.72份；‑60~+80目石英中砂2.7~5.36份；‑80~+120目石英细砂4.29~13.5份。本发明中钨尾矿仅需要压滤，无需高温烘干，减少了工序、节省了能源，进而降低产品成本。
