Abstract
A fire-extinguishing composition is prepared through mixing diammonium hydrogen phosphate, bisodium hydrogen phosphate, dicyandiamide and borax to obtain flame-retarding agent A, mixing 2-(2-butoxyethoxyl) alcohol with water to obtain fire-extinguishing agent B, mixing A with B to obtain concentrated fire-extinguishing agent C, and mixing C with water, and features high fire-extinguishing effect, no poison and no pollution.
Description
The invention belongs to fire service inventory, relate in particular to a kind of fire-extinguishing composition and preparation method thereof.
General burning has three key elements, it is combustible, reach ignition temperature and oxygen, lacking one just can not be on fire, perhaps fire is extinguished, fire-fighting mode in the past is to reduce the temperature (water spray and carbon dioxide) or starvation (the spray chemical agent is to organize disconnected and the oxygen effect) the control intensity of a fire, reach the fire extinguishing purpose, but because the usefulness of extinguishing chemical or use fire-fighting dose are grasped bad, often be difficult to extinguish the blaze at short notice, in addition, the as easy as rolling off a log combustion again of combustible completely of not burning, moreover, present commercially available dry powder, in the powder extinguishing agent such as carbon dioxide and alkyl halide, mostly contain toxicant, it not only is detrimental to health, and contaminated environment, also can destroy atmospheric ozone layer, influence ecological environment in addition.
The object of the present invention is to provide a kind of fire-extinguishing composition and preparation method thereof, this fire-fighting agent is nontoxic, does not pollute, and it can be eliminated the three elements of burning simultaneously, reaches the effect of rapid fire extinguishing, thereby overcomes the defective that existing fire-fighting agent exists.
The present invention adopts following technical scheme:
Fire-extinguishing composition of the present invention, mix with extinguishing chemical B to form by fire retardant A and concentrate fire-fighting agent C, mix with the water of proper proportion again and obtain, described fire retardant A comprises ammonium salt, sodium hydrogen phosphate, nitride and borax, extinguishing chemical B comprises 2-(2-butoxy ethyoxyl) second alcohol and water, among the described fire retardant A, ammonium salt accounts for 22 to 32%, sodium hydrogen phosphate accounts for 17 to 27%, nitride accounts for 8 to 14%, borax accounts for 4 to 8%, 2-among the extinguishing chemical B (2-butoxy ethyoxyl) ethanol accounts for 20 to 30%, water accounts for 8 to 12%, the best proportioning of described fire retardant A is, ammonium salt accounts for 27%, sodium hydrogen phosphate accounts for 22%, nitride accounts for 11%, borax accounts for 6%, the best proportioning of extinguishing chemical B is, 2-(2-butoxy ethyoxyl) ethanol accounts for 24%, water accounts for 10%, the ratio of described concentrated fire-fighting agent C and water is 1: 9, and described ammonium salt can be a diammonium hydrogen phosphate, and nitride can be a dicyandiamide, its preparation method is with diammonium hydrogen phosphate, sodium hydrogen phosphate, dicyandiamide and borax mix forms fire retardant A, 2-(2-butoxy ethyoxyl) second alcohol and water is mixed composition extinguishing chemical B, then fire retardant A and extinguishing chemical B are mixed the concentrated fire-fighting agent C of composition, will concentrate fire-fighting agent C again and mix in 1: 9 ratio with water, make fire-extinguishing composition, described mixed process need at high temperature heat 1 to 5 hour.
The fire-fighting mode of fire-fighting agent of the present invention is that three key elements of burning are eliminated simultaneously; by the fire extinguisher pressure accumulater fire-extinguishing composition of the present invention is sprayed after burning place; 1; it changes into so thing with combustible; the article that sprayed because of this fire-fighting agent; anti-combustion temperature can be up to 1500 ℃; article can not revived; this performance is through Britain fire precautions legislation B.S.476; B.S.5852; the testing authentication of B.S.5867; 2; it is so producing one deck white foam protective layer around the thing; this protective layer is in the middle of burning things which may cause a fire disaster and right thing; can isolate oxygen; 3; the water that discharges in the bubble of high pressure ejection; can lower the temperature rapidly, stamp out the flames, this performance is through Beijing fire science HB5875-85 of research institute testing authentication.
The action principle of fire-extinguishing composition oxygen barrier function of the present invention is; moisture in this constituent can be transformed into steam in the high temperature scene of a fire; water vapour molecule is dispersed in the scene of a fire of high gas concentration; help to disperse and block fresh air and enter again; decomposable material is then stayed burning position in the fire-extinguishing composition; reach the effect of blocking oxygen; fire-fighting agent of the present invention can form water layer film and coherency polymer layer; formation one deck coherency high molecular polymerization layer is protected and is prevented the liquid evaporation between polar solvent burning surface and water layer film, reaches the fire extinguishing purpose.
The action principle of fire-extinguishing composition heat insulation and heat control fire extinguishing of the present invention is, it is phosphoric acid and ammonia that ammonium salt in this constituent and sodium hydrogen phosphate are met thermal decomposition, phosphoric acid has the oxygen barrier cooling effect with the carburization zone that is formed by the combustion thing, produce nontoxic not combustion-supporting gas simultaneously, put out a fire moment, water evaporates in this constituent goes out a large amount of steam, can block fresh air and enter burning place, prevents to revive.
Fire-extinguishing composition of the present invention and preparation method thereof, in mixed process, adopt the mode of high temperature heating, its principle is each component to be synthesized the fire-fighting agent of macromolecule liquid state through thermal response, it is had do not precipitate, no stink, nontoxic, the characteristics of counter tide not, the pH value of this constituent is 7, be fuming and coefficient of heat insulation all lower, so the term of validity is longer, and it is pollution-free not have burn into, safe in utilization.
Fire-extinguishing composition of the present invention pressurization is inserted in the fire extinguisher, and the fire extinguishing effect of itself and conventional fire extinguisher is compared as follows:
Extinguishing chemical kind charging quantity (Kg) fire extinguishing effectiveness value fire-fighting area (m
2)
The present invention 2 B-10 2.0
Sea otter 1,301 2.2 B-2 0.4
Dry powder ABC 2 B-4 0.8
Carbon dioxide 2.3 B-1 0.2
Fire extinguishing effectiveness value B-is the category-B fire extinguishing effectiveness value that test detects in commodity inspection and testing bureau in the table, and listed fire extinguishing effectiveness value of the present invention as can be seen is the highest from table.
The advantage of fire-extinguishing composition of the present invention is, 1, nontoxic, no burn into is pollution-free, this constituent clear, colorless, tasteless, pH value is 7, is neutral chemical substance, need not decompose in ecological environment, can not cause harmful effect to human body and environment, do not damage the ozone layer, these performances are through Canadian Chinese Ministry of Environmental Protection, the testing authentication of units such as Taiwan commodity inspection and testing bureau, Industrial Technology Research Institute, Zhongshan Science Research Inst; 2, comburant can not smouldered, and can not revive; 3, can stamp out the flames rapidly and gland flame; 3, Pen Chu this constituent falls into soil and can become fertilizer, can not cause secondary pollution; 5, the volatile imflammable gas of some chemical substances also there is good inhibitory effect.
