Pottery clay brick and preparation method thereof
The invention belongs to the field of wall material production, and particularly relates to a pottery clay brick and a preparation method thereof, wherein the pottery clay brick raw material is tailings obtained after coal slime is sorted again through sorting equipment, and the tailings contain 60-72% of SiO2, 15-17% of Al2O3, 4-6% of Fe2O3, 0.5-2% of CaO, 0.5-2% of MgO and the balance of other elements, have the heat value of 1.8-2.1 MJ/kg, the plasticity index of 12-18 and the ignition loss of 4-10%, and have the granularity of smaller than 2 mm. According to the invention, the pottery claybrick is not added with any other auxiliary materials excluding the tailings, so that the performance of the pottery clay brick meets or even exceeds the national standard, the reutilization of the coal slime tailings is realized, and the limitation of pottery clay resources is overcome. The preparation process of the pottery clay brick is simple, energy-saving and environment-friendly.
本发明属于墙体材料生产领域，具体涉及一种陶土砖及其制备方法。本发明所述陶土砖原料为煤泥经分选设备再次分选后的尾矿；所述尾矿含SiO为60～72％、AlO为15～17％、FeO为4～6％、CaO为0.5～2％、MgO为0.5～2％，其余为其他元素；尾矿热值为1.8～2.1MJ/kg，塑性指数为12～18，烧失量为4～10％；所述尾矿粒度小于2mm。本发明陶土砖未添加除尾矿外的其他任何辅料，其性能符合甚至超过国家标准，实现了煤泥尾矿的再利用，克服了陶土资源的限制。所述陶土砖的制备工艺简单，节能环保。
