Novel thin-layer plastering mortar and preparation method thereof
The invention discloses novel thin-layer plastering mortar and a preparation method thereof. The novel thin-layer plastering mortar comprises active magnesium oxide, nickel slag, sulfur-fixing ash, amagnesium sulfate solution, a binder and a reaction promoter, the preparation method comprises the following steps: mixing the active magnesium oxide, the nickel slag, the sulfur-fixing ash and the magnesium sulfate solution in parts by weight, stirring at a low speed, standing, adding the binder, stirring at a high speed, standing, and continuously stirring at a high speed. The mortar is excellent in masonry performance, good in fireproof durability and good in cohesiveness, magnesium oxide in the nickel slag powder can react with magnesium sulfate in the later period under the action of thereaction accelerant to generate a magnesium oxysulfate hydration product, and the later-period strength of the mortar is further improved; meanwhile, a large amount of industrial waste residues are used, so that the production cost of the product is greatly reduced, and a new way is opened up for resource utilization of the nickel residues; in addition, the preparation method is simple and convenient and high in operability.
本发明公开了一种新型薄层抹灰砂浆及其制备方法，包括活性氧化镁、镍渣、固硫灰、硫酸镁溶液、粘结剂及反应促进剂；制备时按重量份数将活性氧化镁、镍渣、固硫灰及硫酸镁溶液混合，低速搅拌后，静停，加入粘结剂，高速搅拌，静停，再继续高速搅拌，即可。本发明的砂浆砌筑性能优异，防火耐久性好，粘结性好，且镍渣粉中的氧化镁后期在反应促进剂的作用下能与硫酸镁反应生成硫氧镁水化产物，进一步提高砂浆的后期强度；同时，大量使用工业废渣，产品的生产成本大幅降低，为镍渣的资源化利用开辟了新的途径；此外，其制备方法简便，可操作性强。
