High-iron type full-tailing-based foamed ceramic thermal insulation material and preparation method thereof
The invention discloses a high-iron type full-tailing-based foamed ceramic thermal insulation material and a preparation method thereof, and belongs to the field of foamed ceramic thermal insulation materials, the high-iron type full-tailing-based foamed ceramic thermal insulation material is composed of base materials and auxiliary materials, the base materials comprise, by mass, 25-35% of vanadium titano-magnetite tailings, 15-25% of kaolinite type pyrite tailings and 45-55% of feldspar tailings; the mass of the composite foaming agent is 0.3-1.0% of the total weight of the base material, and the composite foaming agent is composed of silicon carbide and sodium carbonate according to the mass ratio of 1: (0.8-1.2). The vanadium titano-magnetite tailings and the kaolinite type pyrite tailings are used as raw materials, and the vanadium titano-magnetite tailings and the kaolinite type pyrite tailings contain more SiO2 and Al2O3, so that a unique structure of aluminosilicate can be formed under a high-temperature condition, and the vanadium titano-magnetite tailings and the kaolinite type pyrite tailings are used as a framework of the material, so that the material has better mechanical properties. Meanwhile, the feldspar tailings are also added into the raw materials, and the feldspar tailings contain a large amount of SiO2; the content of silicon in the whole structure is further improved, so that the material contains enough SiO2 and Al2O3 to generate the framework.
本发明公开了一种高铁型全尾矿基发泡陶瓷保温材料及其制备方法，属于发泡陶瓷保温材料领域，其由基料和辅料组成，基料按照基料按质量百分比计，其中钒钛磁铁矿尾矿25‑35%，高岭石型硫铁尾矿15‑25%，长石尾矿45‑55%；复合发泡剂的质量为基料总重的0.3‑1.0%，复合发泡剂由碳化硅和碳酸钠按质量比1:0.8‑1.2构成。本申请采用钒钛磁铁矿尾矿、高岭石型硫铁尾矿作为原料，因钒钛磁铁矿尾矿、高岭石型硫铁尾矿中含有较多的SiO2和Al2O3，能够在高温的条件形成铝硅酸盐的独特结构，作为材料的骨架，使得材料具有较好的力学性能。同时，原料中还添加有长石尾矿，长石尾矿中含有大量的SiO2；进一步提高了整体结构中硅的含量，使得材料内具有足够的SiO2和Al2O3，生成骨架。
