| 中文摘要: |
| 介绍了聚脲的特性与燃烧机制，从添加型和反应型2个方面总结了聚脲阻燃改性的研究现状，包括添加卤系、磷系、氮系、纳米阻燃剂，以及通过化学反应引入阻燃元素及结构等方法，系统分析了阻燃机理及各自优缺点。提出添加型阻燃剂存在与基体相容性不佳的问题，反应型阻燃改性技术难度大，但是不存在界面问题，结合不同阻燃剂的优势可实现协同提升的效果。研究结果为提高聚脲阻燃性能提供了技术参考。 |
| 英文摘要: |
| This paper aims to introduce the properties and combustion mechanism of polyurea and summarize the current research status of flame retardant modification of polyurea from two aspects, including the addition of halogen, phosphorus, nitrogen and nano flame retardants, and the introduction of flame retardant elements and structures through chemical reactions. We systematically analyzed the flame retardant mechanism and its advantages and disadvantages respectively and put forword that the additive flame retardant has the problem of poor compatibility with the substrate, while the reactive flame retardant modification is technically difficult with no interface problems. The combination of the advantages of different flame retardants can achieve a synergistic enhancement effect. The research results provide a technical reference for improving the flame retardant performance of polyurea. |
