Development field.
Background technology
In the extinguishing chemical currently used for putting out oil fire, aqueous film-forming foam extinguishing agent is due to pair of its moisture film and foam
Fire extinguishing acts on and has best extinguishing effect again.
The fire extinguishing effect of aqueous film-forming foam extinguishing agent is by floating on water film and froth bed shared on pasta.
When extinguishing chemical is ejected into fuel oil surface, foam scatters rapidly on pasta, and liquid cooling pasta is precipitated.The liquid of precipitation
Inhibiting fuel evaporation jointly with froth bed into water membrane in pasta upper berth spread simultaneously, this not only makes oil and air exclusion, and
And foam can also be reduced oxygen content on pasta by the water vapour that thermal evaporation generates, and inhibit burning.Meanwhile aqueous solution sprawls work
It is put out a fire with foam can be driven to flow to the region not yet put out a fire rapidly again, anti-resume combustion ability is strong.Anionic, cationic,
Amphoteric fluorocarbon surfactant has more application in existing aqueous film-forming foam extinguishing agent.
The electrolyte such as the magnesium chloride containing higher concentration, calcium chloride, sodium sulphate and sodium chloride in seawater, with anionic/
There are stronger interactions between cationic fluorocarbon surfactant, reduce its surface-active so that part aqueous film-forming foam
Extinguishing chemical uses after cannot being diluted with seawater.For the fire that the regions such as offshore work platform, oil tanker and warship occur, do not having
Common aqueous film-forming foam extinguishing agent cannot play a role during water supply, easily lead to greater loss.Therefore, exploitation can use seawater dilute
The aqueous film-forming foam extinguishing agent released has important strategic importance and commercial value.
Table/interfacial activity of both sexes fluorocarbon surfactant and non-ion fluorin carbon surface active agent by electrolyte influenced compared with
It is small, it can be applied to sea water resistance type aqueous film-forming foam extinguishing agent.CN103463790A, CN102284171A and CN1743031A with
DuPont Corporation1157N types or 1203 type surfactants.The non-ionic fluorocarbon surfactant country has
Quality product is supplied, and does not depend on import, and product price is relatively low, suitable for answering in sea water resistance type aqueous film-forming foam extinguishing agent
With.

Description of the drawings
Fig. 1 is the flow chart of the preparation method of extinguishing chemical of the present invention.
Specific embodiment
Make specific introduce to the present invention below in conjunction with the drawings and specific embodiments.
With reference to shown in Fig. 1,6% type sea water resistance type extinguishing chemical provided by the invention is by following components group by mass percentage
Into：Non-ionic fluorocarbon surfactant 1.5-3%, foam stabiliser 0.1-1%, hc-surfactant 2-4%, thickener
0.1-0.5%, anti-burning agent 0.1-0.5%, cosolvent 2-5%, organic solvent 1-5%, buffer solution 0.2-2%, corrosion inhibition for metal

Solvent is diethylene glycol monobutyl ether, one or more in diethylene glycol ether, normal propyl alcohol, isopropanol, n-butanol, n-amyl alcohol
Mixture；Organic solvent in the present invention also has the function of antifreeze simultaneously.
Antifreeze can reduce the solidification point of aqueous film-forming foam extinguishing agent concentrate, make extinguishing chemical that can preserve at a lower temperature
With use.The antifreeze used in the present invention is ethylene glycol or glycerine.Antifreeze in the present invention also has solvent simultaneously
Effect.
Buffer solution can make the pH value of extinguishing chemical keep stablizing during storage, ensure that the performance of extinguishing chemical is stablized.
The buffer solution used in the present invention is trishydroxymethylaminomethane aqueous solution.
Extinguishing chemical may generate corrosiveness in storage to canister inner wall, and need to add in metal inhibitor reduces the work
With.The metal inhibitor used in the present invention is benzotriazole.
In extinguishing agent storage, the organic constituents that bacterium can degrade in extinguishing chemical cause extinguishing property to decline, and need to add in
Bacteriostatic agent inhibits bacteria growth.The bacteriostatic agent used in the present invention is formaldehyde.
Electrolyte in tap water or seawater is more, can influence the performance of surfactant in extinguishing chemical, and the present invention makes
While being not easy with performance by the non-ionic fluorocarbon surfactant of Influence of Electrolyte and both sexes hc-surfactant, use
Chelating agent combines some high volence metal ions, reduces influence of the electrolyte to extinguishing chemical performance.The chelating agent used in the present invention
For sodium ethylene diamine tetracetate.
