摘要：

In order to solve the problem of difficult degradation and ecological harm of traditional fluorinated foam extinguishing agents, this work developed an environment - friendly foam extinguishing agent based on silicon surfactant with low toxicity and high surface activity. Results show that the foam extinguishing agent is a uniform and stable solution, with the freezing point of -10.5◦C, pH of 8.2, expansion of 7.2, 25% drainage time of 4. 0 min, surface tension of 22. 4 mN/ m and positive spread coefficient. The BOD5 / COD value of the foam mixture is 0. 37, which possesses good biodegradability and environmental friendliness. And it exhibits excellent fire extinguishing ability, which can successfully quickly extinguish 55B and 144B water-insoluble flammable liquid oil pan fire. The fire extinguishing performance meets the national standard (IIA level). The research results can lay a theoretical foundation and provide experimental data for the research and development of high-efficiency and envi-ronment-friendly foam fire extinguishing agent. © 2022 Cailiao Daobaoshe/ Materials Review.
