| 摘要: |
| 目的 为了探索类水滑石的低成本制备方法及插层改性增加其新功能的方法，提出类水滑石制备及其功能改性的环保新方向。方法 基于类水滑石的常规制备方法以及矿物原料和固废制备类水滑石的方法，综述类水滑石常规制备方法的优缺点，同时综述增强阻燃性能、吸附性能、催化性能、润滑性能、光催化、抗菌抗肿瘤、抗紫外线等性能的类水滑石的功能改性方法。结论 认为目前类水滑石制备及改性应加强2个方面的研究:利用矿物原料和钢渣、矿渣、粉煤灰等固体废弃物直接制备类水滑石，以降低其制备成本;利用水滑石和类水滑石的层状结构，以及层间阴离子的可交换的特性，加强其多种性能的改性。 |

| Abstract: |
| In order to explore the low-cost preparation method of hydrotalcite-like compounds and the method of intercalation modification to increase its new functions, and the new environmental protection direction of preparation and functional modification of hydrotalcite-like compounds was proposed. By reviewing the conventional preparation methods of hydrotalcite-like compounds and the preparation hydrotalcite-like compounds with mineral materials and solid waste, the advantages and disadvantages of conventional preparation methods of hydrotalcite-like compounds are analyzed, and it summarizes the functional modification methods of hydrotalcite-like compounds to enhance the properties of fire-retardant, adsorption, catalysis, lubrication, photocatalysis, antibacterial, anti-tumor and anti-ultraviolet. At present, the preparation and modification of hydrotalcite-like compounds should be studied in two aspects:one is to directly prepare hydrotalcite-like compounds using mineral materials and solid wastes such as steel slag, slag and fly ash to reduce the preparation cost; the other is to use the layered structure of hydrotalcite and hydrotalcite-like, as well as the characteristics of interlayer anions exchangeable, to strengthen the modification of its various properties. |
