Preparation method of sintering-free vanadium-titanium magnet tailing fine silt-based mineral material composite phase change energy storage material
The invention discloses a preparation method of a sintering-free vanadium-titanium magnet tailing fine silt-based mineral material composite phase change energy storage material. The sintering-free vanadium-titanium magnet tailing fine silt-based mineral material composite phase change energy storage material comprises a sintering-free porous mineral material carrier and a phase change energy storage material, wherein the sintering-free porous mineral material carrier is prepared by taking vanadium-titanium magnet tailing fine silt and ordinary Portland cement as base materials, adding waste glass powder and sodium silicate as coagulation accelerators, adding CTAB and PVA as foaming agents and stabilizing agents, adding water, stirring, foaming, demolding and drying; the component of the phase change energy storage material is myristic acid-capric acid, and the phase change energy storage material is combined with the porous carrier through a normal pressure impregnation process and exists in pores of the porous carrier in a capillary adsorption mode. The building material can be used as a novel heat preservation building material, and energy conservation is facilitated. The main raw material used in the method is the vanadium-titanium magnet tailing fine silt in the commitment region, belongs to a research result of high-added-value comprehensive utilization of the tailing, and is beneficial to relieving tailing pollution in the region and protecting the safety of water and soil resources in the Beijing, Tianjin and Hebei regions.
本发明公开了一种免烧成钒钛磁铁尾矿细泥基矿物材料复合相变储能材料制备方法，包括免烧成多孔矿物材料载体和相变储能材料；其中，免烧成多孔矿物材料载体采用钒钛磁铁尾矿细泥和普通硅酸盐水泥作为基材，添加废玻璃粉和硅酸钠作为促凝剂，添加CTAB和PVA作为发泡剂和稳定剂，加水搅拌发泡，脱模干燥制得；相变储能材料成分为肉豆蔻酸‑癸酸，通过常压浸渍工艺与多孔载体结合，以毛细吸附的方式存在于多孔载体的孔隙中。本发明可作为新型保温建材使用，有助于节约能源。本发明使用的主要原料是承德地区的钒钛磁铁尾矿细泥，属于对该尾矿进行高附加值综合利用的研究成果，有助于缓解该地区的尾矿污染，保护京津冀地区水土资源安全。
