Application of Green Surfactants Developing Environment Friendly Foam Extinguishing Agent

The green surfactants were used to develop environment friendly foam extinguishing agent instead of fluorocarbon surfactant. The surface tension and foam property of a variety of green surfactants were studied by orthogonal experiments. Alkyl glucose amide and organosilicone surfactant were selected. The foam property of alkyl glucose amide and surface tension of organosilicone surfactant were experimentally studied. And finally, the content of two surfactants were determined by considering the interaction of orthogonal experiments. The fire extinguishing performance of 2.5% alkyl glucose amide and 2% organosilicone surfactant containing foam extinguishing agent met the national standard requirements. Conclusion: alkyl glucose amide and organosilicone surfactant can replace fluorocarbon surfactant in foam extinguishing agent. This fire extinguishing agent is completely in conformity with "Stockholm Convention", and environment friendly foam extinguishing agent.
