Abstract:

Magnesium resources are abundant in Qinghai Salt Lake, but it has not been effectively utilized for a long time. These facts lead to the serious waste of magnesium resources and hampered exploitation of potassium and lithium resources. It is of great significance to realize the multi-species, large-scale and high-value utilization of salt lake magnesium resources for the comprehensive development of salt lake resources. Mg-based layered double hydroxides (LDHs) are new type of intercalated functional materials. Based on the adjustable of microstructure, mesoscopic morphology and macroscopic properties of LDHs, the LDHs have been widely used as PVC heat stabilizer, UV-blocking material and smoke suppressant in polymeric materials and road construction. Researchers from State Key Laboratory of Chemical Resource Engineering in Beijing University of Chemical Technology have carried out systematic researches on intercalation structure design and intercalation assembly methods of LDHs based on the utilization of salt lake magnesium resources. Key technologies such as separate nucleation and aging steps and atomic economic reaction have been developed. A large variety of magnesium-based intercalated functional materials have been designed and constructed. The large-scale applications of Mg-based intercalated functional materials have provided new ideas for the comprehensive development and high-value utilization of magnesium resources in salt lake.

Key words: magnesium resources in salt lake, Mg-based intercalated functional material, nanomaterials, preparation, product engineering

摘要:

青海盐湖镁资源丰富,但长期未得到综合利用,造成镁资源严重浪费,同时影响了盐湖钾、锂等资源的开发。开展盐湖镁资源多品种、大规模高值利用,对于促进盐湖资源的综合开发具有重要意义。镁基插层结构功能材料是一类新型层状功能材料,通过对其微观结构、介观形貌和宏观性能等进行调控,已作为PVC热稳定剂、紫外阻隔材料及高效抑烟剂等被广泛应用于橡塑助剂、道路建设及高分子材料抑烟等领域。北京化工大学化工资源有效利用国家重点实验室围绕盐湖镁资源综合利用,开展了系统的插层结构设计与插层组装方法研究,突破了成核晶化隔离、原子经济反应等工程化关键技术,发展了多种镁基插层结构功能材料,并实现了大规模应用,为盐湖镁资源高值利用提供了新思路。
