摘　　要：以烷基糖苷(APG1214和APG0810)与C6氟碳表面活性剂F1157为主要实验材料,逐步取代原水成膜泡沫灭火剂(AFFF)中的C8氟碳表面活性剂(AF4018)制成新的泡沫液配方,分别考察了其铺展性能、泡沫性能、密封性能和灭火性能,分析各新配方的灭火效果。结果表明:不含氟碳表面活性剂的AFFF达不到GB 15308—2006《泡沫灭火剂》规定的灭火要求;在未复配APG的情况下,以F1157替代C8氟碳表面活性剂可以满足灭火要求,但其抗烧时间下降且F1157用量加大;以APG1214或APG0810与较低浓度F1157复配后制成的AFFF不仅可以降低F1157的用量,而且可以明显提高泡沫液的灭火性能,其中APG0810与F1157复配后的灭火效果优于APG1214与F1157复配后的灭火效果。New aqueous film forming foam （AFFF） extinguishing agent formulations were developed by using alkyl polyglucosides （APG1214 and APG0810）,together with C6 fluorocarbon surfactant （Fl157） as main materials to replace C8 fluorocarbon surfactant （AF4018） that used in traditional AFFF extinguishing agent. Performances of the new formulations, including foaming, spreading, sealing of oil surface and fire - extinguishing were investigated. Practical fire - extinguishing efficacy of the various new formulated AFFF products were tested and examined as well. Results showed that： the AFFF product without fluorinated compounds could not meet the requirement of the China National Standard for ＂foam extinguishing agents （GB 15308-2006） ,which indicating that the fluorinated compounds are necessary for the AFFF. The AFFF product formulated with F1157 without APG could extinguish fire, but its heat resistant time was much lower than that of the AFFF formulated with Fl157 together with APG and the concentration of Fl157 has to be greatly increased;while the new AFFF products that formulated with both Fl157 of lower concentration and APG1214 or APGO810,not only could be effective with reduced amount of Fl157,but also improves the heat resistance time and fire - extinguishing performance. Test results also showed that the efficacy of APG0810 is higher than that of APG1214.
