A type of water soluble foam fire extinguishing composite material includes a foaming agent, sodium dodecyl benzene sulphonate (DBN), and water. Said sodium dodecyl benzene sulphonate (DBN) is a replacement for halogenated hydrocarbons, and exerts an extremely great effect on cooling and control of the intensity of a fire; because it has almost no effect on ozone in the stratosphere, it will not worsen global warming.
