Abstract
17 ABSTRACT The present invention discloses an aqueous composition comprising an organicphosphorous containing cornpound and a rheology niodifier, for use in fire controlapplications. The fire control applications include fire extinguishing and flame proofing of solid materials.
Description
COMPOSITION AND METHOD FOR FIRE CONTROL TECHNICAL FIELDThe present invention relates to an aqueous composition for use in fire control applications, for fire extinguishing and as flame retardant.
BACKGROUND Two general principles for the repression of the harin and seriousness ofburning cornbustible materials include: (i) the lowering of the materials tendency tokindle by treatment with a suitable composition, e.g. impregnation with a flameretardant, and (ii) extinguishing of the fire with a suitable liquid, solid or gaseouscomposition. Examples of compositions according to (i) include compositionscontaining e. g. organic phosphorous containing compounds, and according to (ii), e. g.bicarbonate, halogenated hydrocarbon and carbon dioxide containing compositions.
For a generally applicable fire-extinguishing composition, it is desirable thatthe composition has additional fire retarding properties in accordance with the first (i)general principle above. The reason for this is to be found in the mechanisms by whicha fire spreads and re-ignites. A fire spreads by ignition of the material adj acent to theburning material, either by direct contact with the flames or indirectly by the heatradiation. Hence, if the materials tendency to kindle is lowered by the fire-extinguishingcomposition, the spreading of the fire is inhibited and the extinguishing of the samefacilitated. Furthermore, when the flames have been put out, the chances of subsequentre-ignition are diminished in comparison to the case of employment of fire- extinguishing means which are lacking additional fire retarding properties.
Additional desirable properties of a generally applicable fire-extinguishing composition, beside its effectiveness as flame retardant and fire extinguisher, include: 0 Low toxicity. 0 Low environmental impact. 0 Low cost of composing constituents 0 Easy preparation and handling, e.g. by firefighters. 0 No smell or a pleasant smell. v High stability enabling long term storage without decompositionand/or physical changes, e.g. precipitation, of the composition. 0 Suitable physicochemical properties, e.g. viscosity, density andlipophilicity, to allow facile and controlled application by e.g. thespraying through nozzles and/or pumping through fire-hoses. 0 Suitable pseudoplasticity or thixotropy to maximize the adhesion of the composition to the material adjacent to the burning material.
The most well known and used fire-extinguishing composition, which fulfillsmany of the above mentioned desired properties, is common water. When used in fire-fighting, water contacts burning objects which results in sufficient cooling such that theburning objects fall below their combustion or ignition ternperatures, and new ignitionis precluded. In addition, when water contacts hot objects, the water vaporizes toproduce steam, which expands and expels the air necessary for combustion.
However, when a fire is extinguished by spraying water on the fire, only a partof the sprayed water is effective because of water loss, such as by run-off orevaporation. ln order to improve the properties of water in flame proofing and fire-fightingapplications, additives such as fire retarding chemicals, which may retard combustionfor at least brief periods even after the water has evaporated, as well as having a directfire-extinguishing effect, are being developed and are presently in use. Additionaladditives include, for example, thickening agents and different foam forming agents.Various forms of organic and inorganic phosphorous containing compounds representcommonly used fire retarding Chemicals.
EP1065309 Al describes a composition for fire protection treatment of textilematerials consisting of an aqueous solution of carbamide and a complex of theammonium salt of an amidoalkylphosphonic acid and ammonium chloride. The same ora similar composition can be obtained by díssolution of a commercially availableproduct named Noflan®. In addition, a process for fireproofing treatment of textilematerials by employment of this composition is also described. The textile material,which is first allowed to undergo an impregnation with a melamine-type resin and/orsilicon-containing compounds in order to achieve e. g. a good fixation of thephosphorous containing flame retarder, is subsequently treated with the composition, before heat treatment at elevated temperature.
One disadvantage of this composition is the multistep procedure utilized for thefireproofing treatment and e. g. the equipment needed for heating the material Which isbeing fireproofed. Furthermore, this composition is not well suited for storage overprolonged time periods due to physical and/or chemical change and decomposition,respectively.
EP1418178 A1 discloses the ammonium salt of nitrilotris(methylene)triphosphonic acid amide, which is useful as a flame retardant of polymeric materials byaddition to the polymer at the stage of polymer processing, and may be used for thefireproofing of e. g. textiles by treating the same with the corresponding aqueousformulation.
GB2299094 A discloses an aqueous formulation comprising a polymer inwhich an organic phosphorous containing compound has been bonded to the same. Thisformulation may be used for the fire proofing of e. g. textiles. The organic phosphorouscontaining compounds, acting as starting materials to be bonded to suitable reactivefunctional groups of the polymer, include dialkyl phosphites, oligomers ofvinylphosphonic esters, oxoacids of phosphorus and their corresponding salts, andesters or salts of methylphosphonic acid. The material treated with the aqueousformulation, e. g. a textile, is preferably subsequently treated at an elevated temperaturein a drying oven in order to enhance the integrity of the polymer and/or complete thebonding of the organic phosphorous containing compound to the polymer.
A disadvantage, common to all of the above aqueous formulations andcompositions (described in EPl065309 A1, EP1418178 A1 and GB2299094 A), includethe non-optimal physical chemical properties for the application of the same by e. g.spraying or sprinkling. Furthermore, all of the above documents (EP1065 309 A1,EP1418178 A1 and GB2299094 A) fail to mention use of the respective formulation orcomposition in fire-extinguishing applications.
Hence, an improved formulation useful for fire fighting, including fire extinguishing and fire proofing, would be advantageous.

It is another object of the present invention, to provide a composition which iseffective as fire extinguisher and/or flame retardant and which simultaneously exhibitsall of the following properties: low toxicity, environmentally friendly, easy preparationand handling, suitable for long term storage and suitable physicochemical properties toallow facile and controlled application.
These and other objects, which will appear from the following description,have now been achieved by an aqueous composition according to the present invention, which comprises an organic phosphorous containing compound and a rheology modifier. The organic phosphorous containing compound is a compound of forrnula (I), O R-P-NHZ o --M(I) or a complex, solvate or hydrate thereof, wherein M is selected from the group 9 consisting of H, NH4, Na and K, and R is CM; alkyl or a substituent according toformula (Il) få o (cmn o°\ II 2 H /°O T (CH2)n N (CH2)n T O NHZ (n) NHZ Q of the substituent according to formula (II) is independently selected fromthe group consisting of H, NH4, Na and K, and n is an integer number from 1 to 3. Theaqueous composition according to the present invention may be used in fire controlapplications such as, for example, fire extinguishing of burning solid materials and for flame retardation of solid materials.
Further features of the invention and its embodiments are set forth in the appended claims.
DETAILED DESCRIPTION OF THE EMBODIMENTS Several embodiments of the present invention will be described in more detailbelow with reference to the accompanying formulas in order for those skilled in the artto be able to carry out the invention. The invention may, however, be embodied in manydifferent forms and should not be construed as limited to the embodiments set forthherein. Rather, these embodiments are provided so that this disclosure Will be thoroughand complete, and will fully convey the scope of the invention to those skilled in the art.The embodiments do not limit the invention, but the invention is only limited by theappended patent claims. Furthermore, the terminology used in the detailed descriptionof the particular embodiments illustrated in the accompanying drawings is not intendedto be limiting of the invention.
The disclosed aqueous composition essentially comprises an organicphosphorous containing compound and a rheology modifier, such as xhantan gum, andoptionally at least one additional additive, such as a preservative.
The rheology modifier of the composition turns its viscosity to be dependent onshear rate and/or shear rate history. The non-Newtonian, e. g. tixotropic or pseudoplastic,properties of the composition, in combination with the organic phosphorous containingcompound, are highly beneficial in fire-control applications. For example, when thedisclosed composition is pumped through e. g. a nozzle towards a burning material, itattains a fluid like form and is easily and Well spread. When it has reached the burning material, or objects adj acent to the burning material, it attains a stable gel like form andthe tendency of the composition to run off the same or to be blown away by the wind isminimized. Hence, a highly effective flame retardation of the adj acent objects isachieved, Whereby the fire is effectively hindered from spreading while it issimultaneously being extinguished.
According to one embodiment, the organic phosphorous containing compoundmay be a compound of formula (I) and complexes, e. g. the ammonium chloridecomplex, or solvates or hydrates thereof, or a commercially available product which contains at least one compound represented by formula (I) as a main constituent. iiR_P_NH2o-M(1) The generic molecular fragments of a compound of formula (I) are representedby the following molecular fragments, in which: M may be selected from the group consisting of H, NH4, Na and K; and R may be C1_6 alkyl, e. g. methyl, ethyl, n-propyl and í-propyl, or a substituentaccording to formula (II).
The generic molecular fragments of the substituent of forrnula (II) arerepresented by the following molecular fragments, in which: Q may be independently selected from the group consisting of H, NH4, Na andK; and “n” may be an integer number from l to 3, denoting the number of methylene-groups connected to each other to form a linkage between the nítro gen atom and thephosphorous atom. få (CHQÛ (cH9n N O2--U:::O ïi(CH2)n Fí ON (11) lt was surprisingly found that the composition according to the inventionconstitute an excellent fire fighting composition for solid materials, with fireextinguishing and fire retarding properties.
With “fire-extinguish” or simply “extinguish” with reference to flames or fire,or the like, is to be understood herein a treatment which puts out the flames of a fire.With “flame proofing”, “fire proofing”, “flame retardation”, “fire retardation”, or thelike, is to be understood herein a treatment which lowers a materials tendency to kindle,such as, for example, impregnation.
Much of the unexpected effectiveness and many the unforeseen advantages ofthe composition according to the invention are due to the simultaneous presence thereinof the organic phosphorous containing compound and the rheology modifier.
Without being bound to any theory, the inventor believes that the relatively lowviscosity of the composition at the time it is pumped through e. g. a nozzle or the like, iscausing the formation of small drops which are well spread towards the burningmaterial and/or adj acent material which is not yet burning but face a risk of beingignited. When these drops adhere to the burning material or the adjacent material, theyform a film with a relatively high viscosity. Due to the relatively high viscosity, the filmis well adhered to the material without running off and thereby effective as a flameretardant for material adjacent to burning material. The combination of the disclosedcompositions fire extinguishing properties and the above described function as aneffective flame retardant is advantageous in comparison to Newtonian fire extinguishingcompositions of the prior art.
The composition may be used for the extinguishing of fires in combustiblesolid materials for which conventional fire fighting means are presently employedincluding, for example, wood (e. g. forest fires), paper, textile, plastic materials, rubber,such as in car tires, and industrial waste. The composition may also be used for flameproofing of such combustible solid materials or other objects. For example, thecomposition may be sprayed towards objects, e. g. trees, houses, ships, airplanes or thelike, which are adj acent to or near a fire to prevent the fire from spreading to theseobjects.
One advantage of the composition in comparison to other flame retardingagents of the prior art with regard to fire fighting of burning solid materials, for example lO wood and tree-based materials, is its excellent flame retarding properties upon directadministration by e. g. spraying. The suitable physicochemical properties of thecomposition, for example its relatively low viscosity when sprayed but relatively highviscosity when adhered, enables an even spread of the composition on the surface of thesolid material without running of the same. The close and long contact with the solidmaterial then enables the phosphorous containing compound of the disclosedcomposition to effectively penetrate and flame proof the material.
Examples of solid materials, of which the flames when burning may beextinguished with the composition of the invention, include Wood, trees, sawdust, paper,textile, house-refuse and industrial waste.
According to one embodiment, the herein mentioned solid materials may beflame proofed by treatment with the composition according to the invention.
The constituents of the composition according to the invention may be eithercommercially available products, available at a low cost, or easily prepared from cheapcommercially available Chemicals.
The composition according to the invention may be a solution or colloid with ahomogenous appearance. lt may be stable in respect of no, or minimal, observation ofeither of discoloration, precipitation, flocculation, creaming, breaking or coalescencewhen stored over relevant tirne-periods, e. g. over several months or a year at roomtemperature or 20 to 30°C. Thus, it is well suited for storage in e. g. tanks or containers,such as fire-extinguishers, in order to be readily available in case of a fire which needsto be extinguished. Preferably, such containers are made of a material that is notreacting chemically with the composition, for example, a suitable plastic material orstainless steel.
The relative proportions of the constituting ingredients, e. g the organicphosphorous containing compound and the rheology modifier, of the disclosedcomposition, may be varied so that a composition which is optimal for the particular firefighting or fire retarding application is obtained, as well known to the skilled person.For example, the physical properties, e. g. the viscosity, may be fine-tuned by varyingthe relative proportions of the constituting ingredients to generate the desired drop-sizeand/or stream-shape as the composition is discharged through a particular nozzle, orother type of outlet, used in the application of the same.
Furthermore, the selection of the constituting ingredients within the scope ofthe invention may be chosen such that a composition which is optimal for the particular fire fighting or fire retarding application is obtained, as well known to the skilled lO person. For example, the combination of a particular organic phosphorous containingcompound, rheology modifier and preservative may be chosen to optimize the stabilityof the composition so that no or minimal precipitation, or any other physical change,occurs upon storage of the composition in e.g. reservoirs at sites where readily availablefire fighting capabilities are desired.
