中文摘要:
      水滑石(LDH)是一类典型的阴离子型层状材料,具有优异的阻燃性和热稳定性,且低烟、低毒、环境友好。将其与聚合物复合制备复合材料,可以显著提升聚合物的耐火能力,因而受到研究者的广泛关注。本文介绍了LDH的结构特点及其有机改性方法,包括离子交换法、煅烧还原法、一步法和溶剂剥离法。总结了常用于制备聚合物/LDH复合材料的方法,并简述了它们各自的优缺点。重点综述了影响聚合物/LDH复合材料阻燃性的因素,主要包括LDH板层二价和三价阳离子、多金属阳离子的引入和改性剂等方面的影响;简述了其他阻燃材料配合LDH协同阻燃的进展。最后,笔者分析了阻燃型聚合物/LDH复合材料的研究现状,就该材料在产业化推广、进一步提升高效阻燃性能、明确阻燃机理等方面,提出了自己的观点。
英文摘要:
      Layered double hydroxide (LDH) is a typical anionic layered material with excellent flame retardancy and thermal stability, low smoke, low toxicity and environmental friendliness. The preparation of composites by combining LDH with polymers can significantly improve the fire resistance of polymers, which has attracted wide attention of researchers. This paper introduces the structural characteristics, organic modification methods of LDH including ion exchange method, calcination-reconstruction method, one-step method and solvent exfoliation method. The methods commonly used in the preparation of polymer/LDH composites are summarized and also briefly describe their advantages and disadvantages. Furthermore, the factors affecting the flame retardancy of polymer/LDH composites are reviewed, including the effects of LDH ply bivalent and trivalent cations, the introduction of polymetallic cations and modifiers. A brief description of the progress of other flame retardant materials in combination with LDH using synergistic flame retardant. Finally, the author analyzes the research status of flame retardant polymer/LDH composites. The viewpoints of industrialization of polymer/LDH composites, improvement of flame retardant efficiency and clear flame retardant mechanism were put forward.
