摘要:

环境法规对长链氟碳表面活性剂的限制日益严格,而短链复配体系协同机制尚未明确,这制约了高效环保灭火剂的开发进程。系统梳理了短链氟碳灭火剂分子工程策略(链长调控、两性离子设计)与复配技术(氟碳/碳氢协同)优化路径;通过对现有研究的梳理发现,C4—C6短链表面活性剂在活性与环境友好性之间能实现较好的平衡,复配体系可显著降低临界胶束浓度与氟用量,同时提升泡沫稳定性;归纳了复配协同机制,包括阴/阳离子静电作用促进致密膜形成、构象匹配抑制水相迁移等,并总结了从微观分子排布到宏观性能(如界面张力与泡沫稳定性)的定量关联规律。研究结果为理解复配机制、推动灭火剂的合理设计提供了理论参考。

Abstract:

Due to regulatory restrictions on long?chain fluorocarbon surfactants, the synergistic mechanisms of short?chain composite systems developed as alternatives remain unclear, hindering the advancement of high?performance and environmentally friendly firefighting agents. This review systematically outlines optimization strategies for short?chain fluorocarbon firefighting agents, including molecular engineering approaches (chain?length control, zwitterionic design) and compounding techniques (fluorocarbon/hydrocarbon synergy). By synthesizing existing research, it highlights that C4—C6 short?chain surfactants strike a balance between surface activity and environmental friendliness and composite systems significantly reduce critical micelle concentration and fluorine consumption, simultaneously enhancing foam stability. The review summarizes synergistic mechanisms in compounding including electrostatic interactions between anions and cations promoting dense film formation, and conformational matching inhibiting aqueous migration. It also establishes quantitative relationships spanning from microscopic molecular arrangements to macroscopic properties, such as interfacial tension and foam stability. This study provides theoretical reference for understanding the mechanism of compounding and promoting the rational design of fire extinguishing agents.
