Abstract

The invention discloses a hazardous chemical substance fire-fighting foam fire extinguishing agent formula and relates to the technical field of fire fighting. The fire extinguishing agent is composed of lauramidopropyl betaine, an organosilicon surfactant, alkyl glycoside, fatty amine polyoxyethylene ether, sodium dodecyl sulfate, polyacrylamide, xanthan gum, sodium carboxymethylcellulose and a foam stabilizer. The invention further discloses a preparation method of the hazardous chemical substance fire-fighting foam fire extinguishing agent. The method comprises the two steps of preparation of a compound system and mixing with water. Raw materials such as various fluoride-free nonprotein surface active agents, the polyacrylamide, the xanthan gum, the sodium carboxymethylcellulose, a sodium alginate polymer and the foam stabilizer are adopted for preparing the foam fire extinguishing agent, and prepared foam fire extinguishing agent products are good in foaminess and high in foam stability; a large amount of foam can be generated within a short time, and the foam sealing property is good; the foam fire extinguishing agent is used for preventing inflammable goods from making contact with the outside air, and good fire extinguishing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a formulation of a fire-fighting foam fire extinguishing agent for hazardous chemicals and a preparation method for the fire-fighting foam fire extinguishing agent for hazardous chemicals. Background technique [0002] There are many types of foam fire extinguishing agents, mainly including protein, fluoroprotein, aqueous film-forming, solvent-resistant aqueous film-forming and Class A foam fire extinguishing agents, etc., and their production processes are different. Protein and fluoroprotein foam fire extinguishing agents are made of animal protein or vegetable protein in a reactor, partially hydrolyzed with alkali, concentrated, and then added with additives such as stabilizers, preservatives, antifreeze agents, and fluorocarbon surfactants. ;Aqueous film-forming foam fire extinguishing agent is composed of film-forming agent, foaming agent, foam stabilizer, anti-burni...
