Most effectively the present invention can be used for volumetrically suppressing fires of burning solids, such as wood, coal, textile, polymeric material articles; liquid substances, such as benzine, diesel fuel, alcohols, ethers, glycols;.gaseous substances, such as hydrogen, methane:, propane or mixtures thereof;, metals such as light-weight metals: AI, Mg or their alloys, alkali metals, K, Na metal-containing compounds: metal hydrides, metallo-organic, materials.
By "volumetric" fire-suppression we understand creating in a limited space, say, in a room, hold, shop, etc., called a protected space, a medium that does not maintain combustion, which is achieved by feeding gaseous substances or aerosols to the protected space by evenly distributing same in this space in an amount that assures a concentration thereof, which makes combustion and explosion impossible.
Prior art By now, in view of a sharp increase in and growth of industrial potential, the number of fires is increased propertionally, with the chemical and gas-petroleum refining industries suffering in particular, where there can occur emergency ejections of easily inflammable liquids and gas fuels etc, which are dangerously explosive, as well as the wood and coal industries. For ages fires remain one of the most serious accidents on ships. Up to 30% of all disasters on vessels a year come of a destructive action of fires. The efficient extinguishing of fires is an urgent problem of safety of navigation.
One of the most popular compositions is a halogencontaining gaseous composition to be fed to the combustion zone ("Halon"), for instance, Halon 13BT- based on Strifluorobromomethane,Halon. 114B2- based on tetrafluoro- 2 dibromomethane, which is distinguished by high fire-fighting and operation properties, but belongs to the class of ozone-destructive'compositions.
(Review of T 3 NIITESTROIMASH, construction, road-building and municipal engineering, Series 6, "Fire equipment", Issue 3, "State-of-the-art automatic gas fire-suppresion installations", 1983, Moscow, pp. 3-40) In accordance with the protocol of Montreal (1987) concerning international measures toward protection of the ozone layer of the Earth, they will be fully prohibited by 2000 year.
Another wide-spread fire-fighting medium is a composition,based on carbondioxide, which on getting into the seat of fire lowersthe temperature of the combustion zone, thanks to the evaporation of the composition flakes and reduces the amount of oxygen, contained in the combustion S zone.
I!
However, CO 2 based compositions are toxic and tend to affect respiratory tracts of the people finding themselves in the combustion zone, caused by suffocation, resulting in death.
A Halon-based composition likewise exerts a toxic effect on the human body, while I-Ialn thermal decomposition products are distinguished for high corrosion activity.
Moreover, a variety of application has been found in the world by a powder of the type, used for fire-suppresion, which substantially is a mechanical mixture on the basis of, say, sodium bicarbonate or phosphoric-ammonium salts up to 95-97 wt.% with Aerosil or graphite (M.E.
Krasnyanskii "Firefighting and explosion-suppressing powders", 1990, "Donbass", Donetsk, pp. 16-25). Said powder is conveyed to the combustion zone by a gas under pressure. The powder, ejected under pressure forms an air-gas mixture, which blankets flames and suppresses them by isolating same from air oxygen. However, the known powder displays lowered operation properties becau-
I
43T FIAQ7~-itl e 6~7 ao' WV, I 3 se of tendency to caking and lumping, a factor that hampers its feed from equipment to the combustion zone. The said powder is in the main applicable only for fighting local fires.
Known in the art is a fire-suppression composition as shown and described in USP No.3972820. The prior art composition is in reality a solid mixture including 25-85 wt.% of a thermally dispersed halogen-containing organic component, demonstrating a fire-fighting property and selected from a group consisting of hexachlorobenzene, hexabromobenzene, perchloropentacyclodecane;, c- dibromotoluene, 1,2,3,4-tetrachlorodibromobutane, decabromodiphenyl oxide, tribromopentyl alcohol, tetetrabromo-x-diethyl benzene, c(-tetrabromo-o-xylene, octachloronahpthalene, 1,2,4,5-tetrabromobenzene, 1,2,4,5tetrachlorobenzene, polybromonaphthalenes, dibromotetrafluoroctane, 1,2-dibromo-l,1-dichloroethane, 1,2-dibromo- 3-chloropropane, o6-dibromoethyl benzene; 15-45 wt.% of the oxide selected from a group consisting of sodium chlorate, potassium chlorate, sodium perchlorate and perchlorate of potassium; 3-50% wt.% of a binder assuring the binding of a composition, its processibility and combustion in the presence of an oxidant; about 2 wt.% of a catalytic addition to accelerate solidification of the composition.
The distinction of the known composition is its capability, when being burnt, to sublimate a crystalline, thermally dispersed organic component, which brings about a reduction of the specific consumption of the composi.'.on to 128 g/m 3 Due to interaction of the oxidant with the binding agent the heat is liberated for subliming a crystalline, organic, thermally dispersed component, or in other words, a halogen-containing gaseous phase is formed, which inhibits a chemical reaction of combustion in the fire zone, and a solid phase in the form of black that is neutral Sto the chemical reactions, proceeding in the fire zone.
r i I The gas phase of the composition has a harmful effect on the human body and destroys the Earth's ozone layer.
Then, the known composition is toxic because of volatility of the organic compounds, used as a thermally dispersed component; besides said composition is distinguished by lowered vital activity because of a high rate of growth of its mass viscosity, explained by the employment of a catalytic addition, represented by tertiary amines, Lewis acid, metal oxides. In utilizing said known composition under an elevated pressure, say, over 2 atmospheres, one can observe its unstable combustion, entailing its attenuation.
Disclosure of the Invention The basis of the present invention is to create a composition for fire-suppression with improved operating qualities, an expanded range of its application under a reduced specific consumption thereof by means of changing the nature of a thermally dispersed components and by varying the weight percentage of an oxidant, oxygen-containing binder and addition agents and the combustion products of which would be ecologically pure and contribute to protecting the Earth's ozone layer.
There is disclosed herein a fire-fighting composition comprising 1.0 to 35.0 wt% of a thermally dispersible component, 50.0 to 94.0 wt% of an oxidant, 3.0 to 25.0 wt% of 0 an oxygen-containing binder and 1.0 to 25.0 wt% of an addition agent as hereinbefore 20 described, wherein said thermally dispersible component is an inorganic compound selected from the group consisting of chloride, sulfate, sulfide, alkali or earth alkaline °metal phosphate, ammonium salt and a mixture thereof.
0 t o a 0 0 0*0000 0 0 INALI3AAI4931 SAK ;ic The nature of the thermally dispersed component in the above-indicated composition is such that it is selected from a series of salts of inorganic acids,which explains non-volatility of the composition and its ecologic purity. The utilization of the composition according to the invention shows improved operating properties obtained due to an increased share of a finely divided solid phase down to 2 ,4m in aerosol, formed during burning of the composition.
The increased share of the finely divided solid phase in aerosol permits expanding the range of application of said composition, say, in extinguishing "smoldering" fires and burning metals, which is explained by the fact that the finely divided solid phase descends on the burning surface and isolates it from access of the atmospheric oxygen. The selection of an inorganic, thermally dispersed component makes it possible to produce a protective coating in the form of a viscous polymeric film, formed through crystallization'of said finely divided solid phase melt at a temperature of the burning surface.
In addition, the composition according to the invontion exhibits improved operating qualities owing to the fact that the increased share of the finely divided pha- 1 se in aerosol eases the inhibition of chemical reactions of combustion, increasing the likelihood of destruction of the "active" burning centers over the surface of the finely divided phase.
The content of a thermally dispersed component of Jless than 1% by weight in the composition resu: s in that the product of combustion thereof do not coiitribute to continuity of the formed protective coating, which hampers extinguishing "smoldering" fires. Given the contained thermally dispersed component in the composition being over 35 there is observed unstable combustion of the composition because of an insufficient quantity of oxygen therein.
c4 With an oxidant content in the composition amounting r I 6 6 to less than 50 one can observe a lack of oxygen, as a result of which after inflammation the composition does not burn independently. In case the amount of oxidant exceeds 94% by weight, it is impossible to produce said composition and to form a fire-suppression charge therefrom.
With an oxygen-containing binder being present in the composition in the amount of Less than 3 a fire-suppression charge cannot be formed, whereas with its content exceeding 25 the complete burning of the charge is not attained and the burning is accompanied by a great amount of carbon production in the form of black.
If the amount of an addition agent in the composition exceeds 25 the latter does not burn because of the deficit of oxygen therein, whereas if its content in said composition makes less than 1 one cannot achieve homogeneity of the chemical composition of a fire-suppression charge, and, consequently, its even layer after layer burning.
It is recommended to include an oxidant in the composition in the form of potassium perchlorate, or sodium perchlorate, or ammonium perchlorate, or potassium nitrate, or sodium nitrate, or ammonium nitrate, or a mixture thereof.
The choice of the above-indicated oxidants depends on a high content of oxygen therein and the formation in the combustion product of the composition of an additional amount of a finely dispersed solid phase, such as Na 2 0, K 2 0, KOH, K 2
CO
3 Na 2
CO
3 KCl, which inhibits the course of chemical reactions of combustion, a factor that enhances the efficiency of said fire-fighting composition eventually causing a reduction of its specific consumption.
The employment in a composition of a mixture of said oxidizing agents makes it possible to control the burning rate thereof within a wide range of.values, say, from about 0.3 mm/s to about 5.0 mm/s under an atmospheric r I i I- r -7
I"
7 pressure.
j; It is advisable,to include an oxygen-containing binder into the composition in the form of a cellulose ester: ethyl cellulose, acetate cellulose, nitro cellulose or a mixture thereof; or rubber: butadiene nitrile, butyl rubber, urethane, natural, divinyl styrene, divinyl nitrile or a mixture thereof; or a polymer: chlorinated polyvinyl chloride, polyvinyl chloride,polyvinyl butyral, polyvinyl acetate or a mixture thereof: or a resin: epoxy, unsaturated polyester, phenol formaldehyde or a mixture thereof; or their mixture.
The use of the indicated oxygen-containing binders in the composition enables one not only to form a firesuppression charge, but also to decrease the specific consumption of the composition in putting fires out.
When using said esters of cellulose, or their mixture as an oxygen-containing binder in the composition, the latter can be formed into a fire-suppression charge according to the forming process of thermo-setting materials.
According to the same technology there can be formed a charge from a composition, containing as oxygen-containing binding agents the indicated above rubbers, polymers or a mixture thereof.
When usinq said resins or their mixtures as oxygencontaining binders in the composition, the latter are formed according to the technology of "free" moulding or injection moulding to shape a fire-suppression charge.
i- The use of said resins and said cellulose esters in 30 the composition permits expanding the temperature range of said charge application, up to 600C by improving the physico-mechanical properties of the composition, based on an increase in density of polymeric nets in the composition structure.
Besides, the presence of oxygen in the binder contributes to better composition burning and allows a re- ©,gy duction of the oxidant content with a simultaneous inftk4 S. 8 8 crease in the portion of an inorganic thermally dispersable component, which results in a reduced specific consumption of composition for fighting fires.
It is desirable to use potassium chloride as athermally dispersable component in the amount of from 1 to wt. The use of said potassium chloride is motivated by its enhanced ability to bind "active" centers, responsible for the development of combustion in the seat of fire, a factor that has caused a reduction of its content in the composition to 25% by weight. Also, this leads to a reduction of the specific consumption of said composition for fighting fires.
The composition may contain potassium nitrate and potassium perchlorate as an oxidant in the amount of from about 50 to about 85 wt.%.
It is common knowledge that these substances are lowhygroscopic and therefore their nitroduction into the composition eliminates a need in sealing the fire-suppression charges, mounted on river and sea-going vessels. A combination of potassium nitrate and potassium perchlorate explains a high oxygen balance of the composition, which makes it possible to lower the upper limit of their content down to 85 wt.%.
SuCA as The composition must contain -a an addition agent 4 a plasticizer, a combustion modifier, a process admixture, or a mixture thereof.
To form a fire-suppression charge according to the technology of producing thermosetting materials, a plasticizer is needed. With the content of the oxygen-containing binder in the composition being from 3.0 to 10 wt.% according to the invention, a process admixture is added thereto to form a charge by the method of injection moulding.
With the content of an inorganic, thermally dispersable component in the composition from 10 to 35 wt.% and I providing its combustion under a pressure exceeding the
MMMMMMP
atmospheric one, it is necessary to introduce a combustion modifier thereinto.
It is advisable to include a plasticizer into the composition, represented by esters and polyesters from a series of dibutyl-phtalate, dibutyl-sebacinate, tributyl phosphate, glycerol triacetate, tricresyl phosphate or a mixture thereof; organic nitrates: nitroglycerin, dinitratediethylene glycol, dinitratetriethylene glycol or a mixture thereof;,organic azide, including S-triazine series: 2,4-diazido-6-amino-S-triazine, 2,4-diazido-6-azidoethoxy-S-triazine; 2-axido-4,6-diazidoethoxy-S-triazine or a mixture thereof; or their mixture.
The application of said esters and polyesters as well as of organic nitrates is conditioned by utilization in the composition of cellulose esters, rubbers or polymers, or a mixture thereof as an oxygen-containing binder. Besides, organic nitrates increase the oxygen balance of said composition, while their mixture permits expanding the temperature range of application for the fire-suppression charge, say, up to 260 0
C
by lowering the cristallization temperature of the mixture. When used in the composition, organic azides increase the rate of the composition combustion, which makes it possible to increase the content of a thermally dispersable components in the.composition from 25 to 35 which results in an improved efficienty of fire-suppression.
One would desire to include a combustion modifier in- Sto the addition agent in the amount from 1.0 to 15.0 wt.%.
i 5 With the modifier content amounting to about 1 wt.%, the composition does not burn at an environmental pressure exceeding the atmospheric one and it resiststo ignition because of the use of thermally stable oxidants therein.
The content of the combustion modifier in the addition agent in excess of 15 increases the consumption of said composition in fire fighting.
R Depending on the nature of the selected oxidants and I I r .i i U ~I_ inorganic thermally dispersable component, the composition may contain a combustion modifier, represented by a group including carbon, silica, aluminium, alumina, ferrum, ferrum oxide and a mixture thereof.
Carbon may be represented by black, graphite, diamond, and the dispersity of silica, aluminium and alumina, ferrum and ferrum oxide may be varied.
The process admixture contained in the composition, should amount to from 0.5 to 6.0 per cent by weight.
Its optimal content in the composition is associated with the nature of the indicated above oxygen-containing binder and the technology selected to form a firesuppression charge. When moulding procedure is used to form said charge, the optimal content of the process admixture is equal from 3 to 6 whereas when forming it according to the technology of thermosetting materials and "free" moulding and also injection moulding the content of process admixture is from 0.5 to 3.5 per cent by weight.
Embodiments of the Invention Given below are specific examples, illustrating production of the composition for fire-suppression in accordance with the present invention.

Then the obtained homogenized mixture of the binder is added with the crystalline powder of a thermally dispersable component of potassium chloride KC1 in the amount of 1.0 g, the matter being agitated for 3-5 minutes to yield a mechanical mixture of said binder and said thermally dispersable component. The thus prepared mechanical mixture is added with an oxidant, being substantially a crystalline powder, potassium nitrate KNO 3 and potassium perchlorate 4 in the amount of 78.0 g, followed by agitation for minutes to obtain a mechanical mixture of water, a binder, a thermally dispersable co:mponent, and an oxidant.

A repeated rolling operation results in additionally plasticized polymers: polyvinyl acetate and tetrafluoroethylene polymer and also in removing water due to elevation of roll temperature up to 70-90°C. Usually the number of rolling steps is 12 to 20. Then a roll is formed from the resulting web, which is subjected to mou3ding conducted at a temperature from 60 to 90 0 C and at a pressure above 1000 kgf/cm 2 to obtain an intermediate product of the fire-suppression charge having a diameter of 70 mm with and/or without a central channel.

The quantity of water in the reaction is 125.0 g. The resulting suspended matter is added with an addition agent. Then under constant stirring, the addition agent which is a viscous-liquid plasticizer nitroglycerol in the amount of 18.4 g is added to the resulting suspended matter to impart plasticity to the oxygen-containing binder nitrocellulose fibers, a factor that facilitates a further treatment of the composition.

A repeated rolling operation results in the final plasticization of nitrocellulose and in the removal of water due to increased temperature of rolls up to 70-90 9 C. Generally the number of rolling steps is 15 to 20. Thereafter a roll is formed from the web obtained, which is subjected to moulding. The further process of the moulding and forming of-an intermediate product of the fire-suppression charge.is carried out in a way similar to Example 1.
