Solid gel foam fire extinguishing agent, and preparation method and use thereof

Abstract

A solid gel foam fire extinguishing agent includes a material A and a material B; the material A includes the following components in mass percentage: 18% to 25% of an inorganic silicate, 0.25% of sodium carboxymethyl cellulose, 0.25% of sodium alginate, 0.1% to 0.5% of xanthan gum, 0.5% to 1% of polyvinyl alcohol, 0.5% to 1.5% of sodium lauryl sulfate, 0.01% to 0.05% of dodecanol, 0.005% to 0.01% of disodium ethylenediaminetetraacetate, and water as a balance; and the material B includes the following components in mass percentage: 25% of sodium dihydrogen phosphate, 25% of acetic acid, 1% to 1.5% of fatty alcohol polyoxyethylene ether, 0.1% to 0.5% of 3% aqueous film-forming foam, 0.01% to 0.05% of the dodecanol, and water as a balance. The fire extinguishing agent exhibits advantages including low density, low oil wettability, high resistance, high adhesiveness, and foam collapse-resistant properties in fire resistance.
