Environment-friendly A-type foam fire extinguishing agent

Abstract

The invention relates to an environment-friendly A-type foam fire extinguishing agent which is prepared from the following components in parts by weight: 19-30 parts of sodium octyl sulfate, 5-20 parts of C<8-10>alpha-olefin sulfonate, 20-50 parts of ethylene glycol monobutyl ether, 1-5 parts of gellan gum, 0.5-2 parts of dioctyl sodium sulfosuccinate, 0.5-2 parts of S-carboxyethyl mercaptobutanedioic acid, 0.5-2 parts of lauroyl sarcosine and 20-50 parts of water. The environment-friendly A-type foam fire extinguishing agent provided by the invention has excellent fire extinguishing property and low toxicity property.

Description

technical field [0001] The invention belongs to fire extinguishing agents, in particular to an environment-friendly Class A foam fire extinguishing agent. 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-burning agent, anti-freezing agent, co-solvent, preservative, etc., and it can be fully stirred in the mixing tank; Film-forming is to add wate...
