Environment-friendly foam extinguishing agent

Abstract

The invention belongs to the technical field of fire-fighting supplies, and relates to a foam fire extinguishing agent, which is composed of the following components by mass percentage: 1.2% to 3.0% of fluorocarbon surfactant, 12% to 25% of deproteinized solution, and 1.5% of perfluorobetaine ~3.5%, alkyl glycoside 10%~16%, urea 3%~5%, starch 5%~8%, food flavor 0.03%~0.15%, ethylene glycol 10%~20%, xanthan gum 0.1%~ 0.3%, foam stabilizer 0.5%~1.0%, cosolvent 0.8%~1.5%, thickener 0.1%~1.2%, and the balance is water. The composition of the present invention is scientific. Compared with the traditional foam fire extinguishing agent, the present invention has an aromatic smell, lower corrosion rate than the traditional foam agent, can prolong the storage life, has low energy consumption, and produces no three wastes. During production and use It will not pollute the environment, will not cause harm to the human body, and each component is easily biodegradable, with fast cooling speed, no recombustion, stable use, and greatly improved the speed of fire extinguishing.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting supplies, and relates to a foam fire extinguishing agent, in particular to an environment-friendly foam fire extinguishing agent. Background technique [0002] Foam fire extinguishing agent is an effective fire extinguishing agent for extinguishing flammable and combustible liquids. It mainly generates a condensed foam floating layer on the surface of the liquid to suffocate and cool. Foam fire extinguishing agents are divided into chemical foam, air foam, fluoroprotein foam, aqueous film-forming foam and alcohol-resistant foam. [0003] Foam fire extinguishing agent generally consists of foaming agent, foam stabilizer, viscosity reducer, antifreeze agent, cosolvent, preservative and water. Aqueous film-forming foam fire extinguishing agent is also called light water foam fire extinguishing agent or fluorine chemical foam fire extinguishing agent, abbreviated as AFFF in English. It is comp...

Problems solved by technology

[0005] The present invention aims at releasing harmful gases such as hydrogen sulfide and ammonia during the production process of the existing foam fire extinguishing agent. After a certain period of storage, a certain amount of sediment will be produced, which has a strong odor, and the use will cause adverse effects on the environment and affect the operation. Insufficiency such as personnel's health, propose an environment-friendly foam fire extinguishing agent, can solve the above-mentioned deficiencies in the prior art, use more environmental protection, no pollution, can increase the rate of fire extinguishing
