Abstract
A kind of aqueous film-forming foam extinguishing agent of high stability energy, belongs to fire service inventory technical field, is made up of by mass percentage following components：Fluorocarbon surfactant 1.2%~3.0%, non-fluorinated surfactant 0.5%~1.5%, perfluor glycine betaine 1.5%~3.5%, fluorinated alkyl glycine betaine 2%~5%, urea 3%~5%, alhpa olefin sodium sulfonate 5%~15%, lauryl sodium sulfate 10%~15%, APG 10%~16%, ethylene glycol 10%~20%, xanthans 0.1%~0.3%, foam stabiliser 0.5%~1.0%, cosolvent 0.8%~1.5%, thickener 0.1%~1.2%, surplus are water.Instant component science, compared with traditional water is into fire foam, the present invention has excellent water and oil repellence and very low surface tension, when caused foam coverage can form thin film in the pasta of burning, tightly it is covered on pasta, have the function that fire smothering, there is stronger high temperature resistant to act on, the thin film stability of formation is extremely strong, cooling rate is fast, resume combustion is not easy, using stablizing, significantly improves the speed of fire extinguishing.
Description
Technical field
The invention belongs to fire service inventory technical field, is related to a kind of fire foam, particularly relates to a kind of high steady
The aqueous film-forming foam extinguishing agent of qualitative energy.
Background technology
Fire foam be put out a fire to save life and property flammable flammable liquid have efficient fire-extinguishing chemical, it is mainly in liquid surface generation cohesion
Floatation of foam layer, play asphyxia and cooling effect.Fire foam is divided into chemical foam, air foam, fluoroprotein foam, MJPZ
Foam and water-resistant foam etc..
Fire foam is typically by foaming agent, foam stabiliser, visbreaking agent, antifreeze, cosolvent, preservative and water group
Into.Aqueous film-forming foam extinguishing agent is also known as aqueous film forming foam extinguishing chemical or fluorine chemistry fire foam, English abbreviation AFFF.It is by
Fluorocarbon surfactant, non-fluorinated surfactant and the additive and water composition that improve foaming properties.
The thickness of film and stability is not strong caused by existing aqueous film-forming foam extinguishing agent, will divide at 300 DEG C~400 DEG C
Solution, does not reach covering power, moreover, cooling rate is excessively slow so that blow-off velocity is slow, and extinguishing effect is poor, easy resume combustion, stability
Can be poor.
The content of the invention
The present invention does not reach the ability of covering for existing aqueous film-forming foam extinguishing agent thickness, and cooling rate is excessively slow so that
The deficiencies of blow-off velocity is slow, and extinguishing effect is poor, easy resume combustion, and stability is poor, propose a kind of MJPZ of high stability energy
Fire foam, can solve above-mentioned deficiency of the prior art, extinguishing chemical film forming thickness can be strengthened, using stabilization, can be lifted and gone out
The speed of fire.
Technical scheme：A kind of aqueous film-forming foam extinguishing agent of high stability energy, it is characterised in that by with the following group
Divide and form by mass percentage：Fluorocarbon surfactant 1.2%~3.0%, non-fluorinated surfactant 0.5%~1.5%, perfluor beet
Alkali 1.5%~3.5%, fluorinated alkyl glycine betaine 2%~5%, urea 3%~5%, alpha-olefin sodium sulfonate 5%~15%, dodecyl sulphate
Sodium 10%~15%, APG 10%~16%, ethylene glycol 10%~20%, xanthans 0.1%~0.3%, foam stabiliser 0.5%~
1.0%, cosolvent 0.8%~1.5%, thickener 0.1%~1.2%, surplus is water.
The each component mass percent is as follows, fluorocarbon surfactant 1.8%, non-fluorinated surfactant 1.2%, perfluor sweet tea
Dish alkali 3.0%, fluorinated alkyl glycine betaine 2.5%, urea 3.8%, alpha-olefin sodium sulfonate 10%, lauryl sodium sulfate 12%, alkyl sugar
Glycosides 13%, ethylene glycol 15%, xanthans 0.2%, foam stabiliser 0.85%, cosolvent 1.11%, thickener 0.38%, surplus are water.
The foam stabiliser is castor-oil plant sodium alkoxide.
The cosolvent is sodium benzoate.
The thickener is natural gelatin material.
Beneficial effects of the present invention are：A kind of aqueous film-forming foam extinguishing agent of high stability energy proposed by the present invention, component
Science, compared with traditional water is into fire foam, the present invention has excellent water and oil repellence and very low surface tension,
When caused foam coverage can form thin film in the pasta of burning, tightly it is covered on pasta, reaches the work of fire smothering
With with stronger high temperature resistant effect, the thin film stability of formation is extremely strong, and cooling rate is fast, is not easy resume combustion, using stablizing, greatly
Amplitude improves the speed of fire extinguishing.
