Methanol high-efficiency alcohol resistant aqueous film-forming foam fire extinguishing agent and preparation method thereof

Abstract

The invention provides a methanol high-efficiency alcohol resistant aqueous film-forming foam fire extinguishing agent and a preparation method thereof. The composition formula comprises the following components in parts by weight: 300-400 parts of deionized water, 6-10 parts of sodium benzoate, 50-100 parts of urea, 5-9 parts of xanthan gum, 10-40 parts of cocoalkanoylamido propyl betaine, 100-400 parts of APG (Alkyl Polyglycoside), 80-200 parts of ethylene glycol, 10-60 parts of ethylene glycol monobutyl ether, 10-60 parts of F115710, 10-60 parts of F1203, 10-40 parts of F1460 and 10-60 parts of phosphate buffer. The product has the advantages of low cost, suitability for fighting a methanol fire disaster, suitability for not only fresh water foam fire extinguishing but also seawater foaming fire extinguishing, extremely small change in foam property and fire extinguishing performance after being mixed with seawater or fresh water according to a use mixing ratio, high foaming multiple, long 25 percent drainage time and stable foaming.

Description

technical field [0001] The invention relates to the field of fire extinguishing agents, in particular to a methanol high-efficiency solvent-resistant aqueous film-forming foam fire extinguishing agent and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy and society, the demand for energy is increasing. Facing the energy situation of lack of oil and gas, vigorously developing new coal chemical projects with coal as raw material has found a way out to solve this problem. Coal-to-methanol is an important reaction type in the field of new coal chemical industry, which can produce a large amount of methanol, and methanol can not only continue to produce olefins, dimethyl ether and other products through chemical reactions, but also can be used as a clean fuel in methanol gasoline, play an important role in the application of fuel cells. Therefore, my country is currently vigorously developing the coal-to-methanol indu...

Problems solved by technology

And the currently used anti-solvent aqueous film-forming foam fire extinguishing agent is also not suitable for mixing with seawater for fire extinguishing, which is mainly due to the nature of the fluorocarbon surfactant and anti-burning agent selected by it. Once it is mixed with seawater, The performance of fluorocarbon surfactants and anti-burning agents will become extremely unstable, which will have a great impact on foam performance and fire extinguishing performance
