摘　　要：研制无氟非蛋白泡沫灭火剂,测试了复配体系的发泡性能与泡沫稳定性、泡沫在汽油表面的铺展性及泡沫对汽油的密封性。结果表明,当LAB、SS、PEAA、APG及SDS质量比为5∶5∶5∶25∶1时,复配体系的发泡效果及泡沫稳定性最好;当PAM、XG、CMCS及SA的质量比为1∶1∶3∶1时,与复配发泡体系配制的灭火剂具有最佳的发泡性、泡沫稳定性及汽油密封性能。灭汽油火实验结果表明,按最优配比配制的泡沫灭火剂具有优良的灭火性能。A kind of non-fluorinated and non-protein surfactant foam extinguishing agent were prepared with adopting orthogo- nal experiment method by using lauryl amide propyl betaine （LAB）, silicon surfactant （SS）, polyoxyethylene alkyl amine （PEAA）, alkyl polyglucoside （APG）, and sodium dodecyl sul- {onate （SDS） as the foaming agents, and polyacrylamide （PAM）, xanthan gum （XG） and carboxymethylcellulose sodi- um （CMCS） as the foam stabilizers. The performance of foa ming and foam stability of the complex system, spreading per- formance of foam on the gasoline and sealing performance of foam to gasoline were tested in detail by Roche bubble instru- ment, surface tensiometer and sealing experiments. The results show that when the mass ratio of LAB, SS, PEAA, APG and SDS is 5 ： 5 ： 5 ： 25 ： 1, the prepared complex surfactants sys- tem has the best foaming performance and foam stability; when the mass ratio of PAM, XG, CMCS and SA is 1 ： 1 ： 3 ： 1, the prepared foam extinguishing agent by using the complex surfac rants system and mixed foam stabilizer have the best foaming, foam stability and sealing performance. The results of gasoline fire extinguishing experiment indicates that the foam extinguis hing agent prepared with the optimum formula has good fire ex- tinguishing performance, and there is a prospect to develop a kind of novel practical product.
