Degradable class-A foam extinguishing agent

Abstract

The invention discloses a degradable class-A foam extinguishing agent. The degradable class-A foam extinguishing agent is prepared from the following raw materials in parts by weight: 19-30 parts of sodium dodecyl sulphate, 5-20 parts of alpha-olefin sulfonate, 20-50 parts of ethylene glycol, 1-5 parts of carboxymethyl cellulose, 0.5-2 parts of dibenzyl phenol polyoxyethylene ether, 0.5-2 parts of S-carboxyethyl thiodisuccinic acid, 0.5-2 parts of methyl 4-hydroxybenzoate and 20-50 parts of water. The degradable class-A foam extinguishing agent provided by the invention is excellent in extinguishing performance and low-toxicity performance.

Description

technical field [0001] The invention belongs to fire extinguishing agents, in particular to a degradable 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 water-soluble p...
