Description
Technical field
The present invention relates to a kind of low temperature resistant premixed type fire foam and preparation method thereof.
Background technology
When a fire, all kinds of extinguishing devices have played huge effect.In existing fire fighting extinguisher, foam goes out
Fiery device application is wider, in addition to fixed and semifixed fixed froth installation, mobile foamite system (serial foam annihilator and
Device etc.) it is widely recognized because new-product development speed is fast, easy to operate, fire extinguishing is rapid.But the series of products are used
Extinguishing chemical be mostly diluted using foam solution stoste after it is directly filling use in a reservoir, even if foam solution stoste is in itself
Freezing point reaches -40 DEG C, but after being diluted with water to concentration, such as 3% type fire foam, in 3 parts of foam fire-fightings during use
97 parts of water are added in agent；6% type fire foam, 94 parts of water are added during use in 6 parts of fire foams, using directly adding water
The extinguishing chemical freezing point of dilution can rise very rapidly up to 0 DEG C -5 DEG C.Therefore, the fire foam of the serial extinguishing device storage can not
Applied in low temperature environment so that the popularization and application of the serial extinguishing device, which receive, significantly to be limited.
Therefore, it is " a kind of to ooze certainly in patent of invention CN102614614A in order that extinguishing chemical can reach low temperature resistant effect
In the anti-resume combustion extinguishing chemical of saturating type ", substantial amounts of alcohols material such as ethylene glycol, 1,3-PD, glycerine etc. are added, can just make to coagulate
Solid point reaches -30 DEG C, and alcohols material has combustibility, and when addition is excessive, combustion-supporting effect can be produced in fire extinguishing procedure, because
This, is not a good solution using simple addition alcohols material.
In patent of invention 200710120280.X " water-based extinguishing agent ", there is provided a kind of extinguishing chemical, lived containing fluorine surface
Property agent, emulsifying agent or fatty alcohol, fire retardant, anion surfactant, thickener, urea and water, and optional are antifreeze
Agent.With A classes of going out, B classes, soluble liquid fuel, appliance fire performance.The antifreezing agent that premixed liquid prepares different proportion can
Directly used under -5 DEG C~-40 DEG C cryogenic conditions.The patent of invention needs again to add when extinguishing chemical stoste is configured to premixed liquid
Entering anti-icing fluid, increase a mixed process again, actual operation is cumbersome, meanwhile, antifreezing agent is also all that the alcohols such as ethylene glycol are molten
Agent.
The content of the invention
One of technical problems to be solved by the invention are that fire-fighting medicament adds water can not be in low temperature after mixing in the prior art
The problem of environment uses, there is provided a kind of new low temperature resistant premixed type fire foam, the extinguishing chemical have straight at low ambient temperatures
Connect the advantages of being employed without adding water mixing.The two of the technical problems to be solved by the invention are to provide a kind of technology with solution
A kind of preparation method of the corresponding low temperature resistant premixed type fire foam of one of problem.
One of to solve the above problems, the technical solution adopted by the present invention is as follows：A kind of low temperature resistant premixed type foam fire-fighting
Agent, including pour-point depressant, film forming agent, foaming agent, bleeding agent, foam stabilizer, preservative, by mass percentage：Pour-point depressant 10%-
20%th, film forming agent 0.1%-1.0%, foaming agent 0.5%-2.0%, bleeding agent 0.05%-0.2%, foam stabilizer 0.2%-
1.0%th, preservative 0.1%-0.5%, other additive 2%-5%, remaining is deionized water；The pour-point depressant is bicarbonate
With the mixture of polyalcohol.
In above-mentioned technical proposal, it is preferable that the mass ratio of bicarbonate and polyalcohol is 4~10：6~10.
In above-mentioned technical proposal, it is preferable that the pour-point depressant be ammonium hydrogen carbonate, saleratus, sodium acid carbonate and n-butanol,
The mixture of glycerine.
In above-mentioned technical proposal, it is preferable that film forming agent is perfluoroalkyl betain or perfluoroalkyl quaternary amine iodide, is foamed
Agent is Cocoamidopropyl betaine, lauryl amine oxide, lauryl sodium sulfate, dodecyl sodium sulfate, detergent alkylate
At least two in sodium sulfonate, alpha-olefin sodium sulfonate, bleeding agent is AEO or isooctanol polyethoxylate phosphoric acid
Ester；Foam stabilizer is a kind of in ethylene glycol monobutyl ether, diethylene glycol monobutyl ether, triethylene glycol butyl ether, and preservative is sodium benzoate, mountain
It is a kind of in potassium sorbate, sodium lactate.
In above-mentioned technical proposal, it is preferable that other additives are urea.
In above-mentioned technical proposal, it is preferable that freezing point reaches -35 DEG C.
For solve the above problems two, the technical solution adopted by the present invention is as follows：A kind of low temperature resistant premixed type foam fire-fighting
The preparation method of agent, adds deionized water in mixing kettle, is warming up to 40 DEG C -50 DEG C, adds bicarbonate and is sufficiently stirred
Dissolving, add polyalcohol；After adding additive stirring and dissolving, temperature is reduced to normal temperature；Film forming agent is continuously added to be mixed；Add
Enter foaming agent and be stirred mixing；Add bleeding agent and be stirred dissolving；Add foam stabilizer；It is complete to be eventually adding preservative dissolving
Afterwards, it is 7-9 that adding citric acid or sodium hydroxide solution, which adjust pH, obtains the low temperature resistant premixed type fire foam.
The invention provides a kind of low temperature premixed type fire foam and preparation method, can be effectively improved current fire-fighting medicine
After agent directly adds water to mix, freezing point rise, it is impossible to apply at low ambient temperatures so that advanced fixed froth installation is because without suitable
Suitable fire foam and the defects of influence popularization and application.The low temperature resistant premixed type fire foam of the present invention, its freezing point reach
, can be directly filling in extinguishing device to subzero 30 DEG C so that extinguishing device can be applied in environment at low temperature, quickly put out
A, B and E classes fire, the application places and scope of device have been widened.The extinguishing chemical mainly by pour-point depressant, film forming agent, foaming agent, ooze
The additive composition such as saturating agent, foam stabilizer, with freezing point is low, blow-off velocity is fast, closed performance is good, anti-resume combustion ability is strong, efficient
The features such as energy-conserving and environment-protective, it is more suitable for, in cold district and field use, being directly potted in all kinds of mobile froth apparatus
In, have the characteristics that freezing point is low, blow-off velocity is fast, closed performance is good, energy-efficient.It can effectively ensure that in low temperature environment
In, applied the premixed type fire foam is directly filling in all kinds of fixed and mobile froth apparatus and device,
Also directly filling can be used in foam annihilator, substitute existing usual foam extinguishing chemical, widened fire-fighting foams fire extinguisher,
The application of device and device, achieve preferable technique effect.
Below by embodiment, the invention will be further elaborated, but is not limited only to the present embodiment.
