Method for preparing high-strength thermal insulation building block from graphite tailings
The invention discloses a method for preparing a high-strength heat preservation building block from graphite tailings, and relates to the technical field of composite materials; according to the process method, graphite tailings, cement and kaolin are used as main raw materials; the graphite tailings are deeply pretreated, magnetic components and active metal oxides in the graphite tailings are removed, and the graphite tailings are subjected to expansion treatment, so that the specific surface area of the graphite tailings is increased, the strength of the thermal insulation building block is improved, the density of the thermal insulation building block is reduced, and the dead weight of the thermal insulation building block is reduced.
本发明公开了一种由石墨尾矿制备高强保温砌块的方法，涉及复合材料技术领域，该工艺方法以石墨尾矿、水泥和高岭土为主要原料，本发明对石墨尾矿进行深入的预处理，去除石墨尾矿中的磁性组分和活泼金属氧化物，并对石墨尾矿进行膨化处理，提高石墨尾矿的比表面积，进而提高保温砌块的强度，同时降低保温砌块的密度，减小自重。
