Abstract
The present invention discloses a foam material for fire prevention and extinguishing and a preparation method and a use thereof. The foam material for fire prevention and extinguishing comprises the following raw materials in parts by weight: 2-4 parts of foaming agent, 2.5-3.5 parts of foam stabilizer, 10-16 parts of expandable graphite, and 100 parts of water. The foam material for fire prevention and extinguishing has a foaming multiple up to 15-30 times, a viscosity of only 700 mPa·s at a flow state, and the foam could be stable for more than 12 h. After being transported to an ignition point of the goaf via the mine grouting pipeline, the foam material for fire prevention and extinguishing can spread and pile in a large area in the goaf, and thus cover and plug the float coal at low and high places, with a piling height above 1.5 m.
