Abstract

In recent years, research has focused heavily on the investigation of functionalized ammonium polyphosphate (APP) flame retardants to improve the fire safety of epoxy resins (EP). The reason for this is the dual nature of APP's performance in fire protection of EP. This article provides a comprehensive overview of the advances in the use of functionalized APP flame retardants to improve the fire resistance of EP materials. It then presents the improvement of the modification of the functionalized APP flame retardants in terms of the hydrophobicity, compatibility and catalytic ability of the flame retardants, as well as the effects on the fire resistance, heat resistance, smoke reduction and mechanical properties of the EP composites. After the summary and comparison of the relevant studies, it is clear that the functionalized APP flame retardants can effectively improve the fire safety of EP composites and offset the adverse effects of APP in EP flame retardant applications. In addition, APP flame retardants can obtain various excellent functions through the use of materials with different properties, and the interaction between APP and materials can also lead to more efficient fire protection. However, the current problem is to find ways to streamline the process and minimise the costs associated with functionalized APP flame retardants, as well as to use them effectively in industrial production. We hope that this review can provide valuable hints and insights for the practical application of functionalized APP in EP and perspectives for future research.

利用聚磷酸铵构建新型环氧树脂阻燃体系的最新进展
近年来,研究主要集中在功能化聚磷酸铵(APP)阻燃剂的研究上,以提高环氧树脂(EP)的防火安全性。究其原因,是因为 APP 在 EP 防火方面具有双重性能。本文全面概述了使用官能化 APP 阻燃剂提高 EP 材料防火性能的进展。然后从阻燃剂的疏水性、相容性和催化能力等方面介绍了官能化 APP 阻燃剂改性的改进情况,以及对 EP 复合材料的耐火性、耐热性、降烟性和机械性能的影响。经过对相关研究的总结和比较,可以看出官能化 APP 阻燃剂可以有效提高 EP 复合材料的防火安全性,抵消 APP 在 EP 阻燃剂应用中的不利影响。此外,APP 阻燃剂可通过与不同性质的材料配合使用而获得各种优异的功能,APP 与材料之间的相互作用也能带来更高效的防火效果。然而,目前的问题是如何简化功能化 APP 阻燃剂的生产工艺,最大限度地降低相关成本,并将其有效地应用于工业生产。我们希望本综述能为功能化 APP 在 EP 中的实际应用提供有价值的提示和见解,并为未来的研究提供展望。
