摘要
聚磷酸铵(APP)作为传统膨胀阻燃剂(IFR)体系中的酸源和气源,常被用于环氧树脂(EP)阻燃,但其水敏性和高极性导致其与EP界面相容性较差,可对EP性能产生负面影响。文章阐述对APP进行功能化改性的方法,包括微胶囊化、离子交换和表面接枝等,分析改性APP对纯EP及其复合材料阻燃性能的影响,总结改性APP在EP阻燃领域中的应用及阻燃机理,并对APP功能化阻燃改性的发展趋势进行展望,旨在提高APP与EP的相容性和耐受性,拓宽EP复合材料的应用范围。
Ammonium polyphosphate(APP),serving as an acid source and gas source in traditional intumescent flame retardant(IFR)systems,is commonly used for Flame Retardancy of epoxy resin(EP).However,its hygroscopic nature and high polarity lead to poor interfacial compatibility with EP,which can negatively impact the properties of EP.The article discusses methods for the functional modification of APP,including microencapsulation,ion exchange,and surface grafting.It analyzes the effects of modified APP on the flame-retardant properties of pure EP and its composites,summarizes the application and flame-retardant mechanisms of modified APP in the field of EP flame-retardancy,and looks forward to the development trends of APP functional flame-retardant modifications.The aim is to improve the compatibility and tolerance between APP and EP,thereby expanding the application range of EP composites.
