Embodiment 1

[0017] Super cold-resistant environmental protection aqueous film-forming foam fire extinguishing agent, mainly composed of the following components in terms of mass percentage: fluorocarbon surfactant 2%-16%, hydrocarbon surfactant 10%-30%, co-solvent 1.5%-10% , antifreeze 5%-20%, also includes water with the above ingredients constituting a mass percentage to 100%; the fluorocarbon surfactant is an amphoteric fluorosurfactant F1470 developed based on C6 short chain technology, which does not contain C8 long The perfluorooctane sulfonate developed by the chain; the hydrocarbon surfactant is a non-ionic surfactant alkyl glycoside; the co-solvent is diethylene glycol monobutyl ether; the antifreeze is urea;

[0018] In this example, the amphoteric fluorosurfactant F1470 developed based on the C6 short-chain technology was selected, and it did not contain the fluorocarbon surfactant of perfluorooctane sulfonate developed with the C8 long-chain; it would not decompose into fluorin...

Embodiment 2

[0020] Super cold-resistant environmental protection aqueous film-forming foam fire extinguishing agent, mainly composed of the following components by mass percentage: fluorocarbon surfactant 10%-20%, hydrocarbon surfactant 5%-25%, co-solvent 8%-15% , Antifreeze 15%-30%, also includes water with the above ingredients constituting mass percentage to 100%; fluorocarbon surfactant is an amphoteric fluorosurfactant F1470 developed based on C6 short chain technology, which does not contain C8 long The perfluorooctane sulfonate developed by the chain; the hydrocarbon surfactant is a non-ionic surfactant alkyl glycoside; the co-solvent is diethylene glycol monobutyl ether; the antifreeze is urea;

[0021] In this embodiment, by improving and optimizing the ratio of the components of the foam fire extinguishing agent, the content of cosolvent, antifreeze and hydrocarbon surfactant is increased to improve the high durability of the foam fire extinguishing agent under extremely cold con...

Embodiment 3

[0023] Super cold-resistant environmental protection aqueous film-forming foam fire extinguishing agent, including amphoteric fluorosurfactant F1470 developed based on C6 short-chain technology, which does not contain 10% of fluorocarbon surfactant developed with C8 long-chain perfluorooctane sulfonate , 25% non-ionic surfactant alkyl glycoside hydrocarbon surfactant, 6% diethylene glycol monobutyl ether cosolvent, 15% urea antifreeze, and 44% water;

[0024] Among them, in the case of 3% AFFF and -40°C, the data in Table 1 are obtained:

[0027] Table 1

[0028] From the above data, it can be shown that the foam fire extinguishing agent has a very stable foaming ratio, liquid analysis time, fire extinguishing time and anti-burning time when the foam fire extinguishing agent is around -40°C, which can further prove that the super cold-resistant environmental protection water composition Membrane foam fire extinguishing agent can be used stably in extre...

Abstract

The invention relates to the technical field of fire extinguishing agents, and especially relates to a super-cold-resistant environment-friendly aqueous film-forming foam fire extinguishing agent, and solves the problem that in the prior art, a foam fire extinguishing agent is very difficult to use and store in an extremely cold environment. The super-cold-resistant environment-friendly aqueous film-forming foam extinguishing agent mainly comprises, by mass, 2-16% of a fluorocarbon surfactant, 10-30% of a hydrocarbon surfactant, 1.5-10% of a cosolvent, 5-20% of an anti-freezing agent, and the balance of water. The nonionic surfactant alkyl glycoside is selected as the hydrocarbon surfactant, and the nonionic surfactant alkyl glycoside can prolong the drainage time, is mild to a human body and is biodegradable, so that the environmental protection property of the foam extinguishing agent is greatly improved; and through the combination of the cosolvent and the anti-freezing agent, the cold resistance of the foam extinguishing agent is greatly improved, so that the super-cold-resistant environment-friendly aqueous film-forming foam extinguishing agent is realized.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing agents, in particular to a super cold-resistant environment-friendly aqueous film-forming foam fire extinguishing agent. Background technique [0002] Foam fire extinguishing agent, as the first choice for extinguishing oil fires at home and abroad, has played a vital role in ensuring the safety of people's lives and property. However, in recent years, as environmental protection issues have become increasingly prominent, more and more attention has been paid to protecting and improving the environment from foreign countries to domestic countries and from countries to localities. [0003] However, during the use and storage of foam fire extinguishing agents, there are potential risks to the environment caused by the chemicals contained in them. At the same time, under extreme conditions in Northeast China, the daily storage of conventional foam fire extinguishing agents has become a pr...
