Abstract

The invention belongs to the technical field of fire-fighting materials, and particularly relates to a foam extinguishing agent and a preparation method and application thereof. The foam extinguishing agent provided by the invention comprises the following components in parts by weight: 200-400 parts of a foaming agent, 50-70 parts of a foam stabilizer, 15-40 parts of a surfactant, 20-80 parts of urea, 50-90 parts of a solvent and 400-600 parts of water, wherein the foaming agent comprises at least two of lauryl sodium sulfate, alkyl glucoside and propyl betaine. The foam extinguishing agent prepared by adopting at least two of lauryl sodium sulfate, alkyl glucoside and propyl betaine as the foaming agents and cooperating with the foam stabilizer, the surfactant, the urea, the solvent and the water is good in freezing resistance and melting resistance, low in corrosion, capable of extinguishing fire efficiently and rapidly and non-toxic to human bodies and the environment.

Description

technical field [0001] The invention belongs to the technical field of fire fighting materials, and in particular relates to a foam fire extinguishing agent and a preparation method and application thereof. Background technique [0002] Foam fire extinguishing agent is an effective fire extinguishing agent that can put out flammable and flammable liquids. It mainly generates a condensed foam floating layer on the surface of the liquid, which plays the role of suffocation and cooling. Foam fire extinguishing agents are divided into chemical foam, air foam, fluoroprotein foam, aqueous film-forming foam and anti-solvent foam. Among them, the water film-forming foam fire extinguishing agent is a foam fire extinguishing agent that forms a layer of water film on the surface of the hydrocarbon liquid based on hydrocarbon surfactant and perfluorooctane sulfonyl compound fluorocarbon surfactant. It is suitable for extinguishing fires caused by non-water-soluble liquid fuels, and is ...
