摘要
聚磷酸铵(APP)是一种重要的无机阻燃剂,是膨胀型阻燃剂的主要成分之一。介绍了I-型和II-型聚磷酸铵的结构、性质,着重讨论了I-型和II-型聚磷酸铵的合成方法、改性途径的研究新进展,以及I-型聚磷酸铵到II-型聚磷酸铵的转化机理、转化方法。研究目的在于制备难溶于水的聚磷酸铵。
Ammonium polyphosphate(APP) is an important inorganic flame retardant,which is used as one of the main ingredients of intumescent flame retardants.In this article,the structure and properties of ammonium polyphosphate form I and II are introduced. Especially,recent progresses of research on the methods of synthesis and modification of ammonium polyphosphate are discussed,and the mechanism and method in the phase transition of APP form I to II are described.Research is mainly aimed at the preparation of water-insoluble ammonium polyphosphate.
