▎ 摘　　要

NOVELTY - Preparing fluorinated graphene oxide extinguishing agent comprises (a) adding fluoride in the graphene oxide solution and sealing the hydrothermal reaction, where the fluoride is hydrofluoric acid, sodium fluoride, ammonium fluoride, and/or lithium fluoride to obtain the fluorinated graphene oxide gel, (b) adding gelatin into the fluorinated graphene oxide gel obtained in step (a) and ultrasonically processing; where the mass ratio of the fluorinated graphene oxide and gelatin protein is 1:10-1:100; (c) adding hydrocarbon surfactant and alcohol foam stabilizer into the solution obtained in step (b) and stirring. USE - The method is useful for preparing fluorinated graphene oxide extinguishing agent. ADVANTAGE - The method avoids the problem of fluoride pollution in the traditional water-forming fire extinguishing agent. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a fluorinated graphene oxide extinguishing agent prepared by the method
