Definitions

  • the present invention relates to the use of water-swellable polymers based at least partly on at least monounsaturated monomers containing sulfonic acid groups, as an additive for extinguishing water, which has an increased NaCl content, in fire prevention and fire fighting.
  • polymer additives with thickening properties are used to increase the viscosity of the fire-extinguishing water, in order to achieve a better than in water adhesion of the fire extinguishing agent to surfaces, especially on inclined surfaces.
  • EP 0 774 279 B1 discloses water additives for increasing the viscosity, which have small proportions of acrylamidopropanesulfonic acid (AMPS). However, these polymers are not suitable for saline aqueous solutions.
  • AMPS acrylamidopropanesulfonic acid
  • the dissolved ions thus undesirably convert the ionic gel to a non-swellable nonionic gel.
  • the salt content problem is solved by adding ionic surfactants to the polymer surface.
  • ionic surfactants such surface-active substances are unsuitable for industrial use and therefore are not considered as bulk goods for fire prevention and fire fighting in question.
  • the object of the present invention is therefore to identify water-swellable polymers which can be used as additives for extinguishing water having a high salt content and essentially retain their swelling properties in saline water.
  • the object is achieved according to the invention by the use of water-swellable polymers which are based at least partially on at least monounsaturated monomers containing sulfonic acid, as an additive for saline fire extinguishing water in fire prevention and fire fighting.
  • saline-containing extinguishing water means any aqueous liquid which has the largest salt content of common salt (NaCl) and which preferably has a total salt content of 1 to 28% by weight, more preferably 1 to 10% by weight and most preferably Has 2 to 5% wt .-% total salt content. Most preferred is saline water having a total salt content of 3 to 4 weight percent. Seawater is most preferably preferred as saline extinguishing water, as described, for example, in Römp's Chemie Lexikon (Volume 3, 8th edition, see 1596, 1983).
  • the polymers to be used according to the invention are prepared at least partially from at least one monosaturated monomer containing sulfonic acid groups, preferably from aliphatic or aromatic vinylsulfonic acids, particularly preferably allylsulfonic acid, methallylsulfonic acid, styrenesulfonic acid, acrylic sulfonic acid or methacrylsulfonic acid, most preferably sulfoethyl acrylate, sulfoethyl methacrylate, sulfopropyl acrylate, Sulfopropyl methacrylate, 2-hydroxy-3-methacryloxypropyl sulfonic acid, and most preferably 2-acrylamidopropane sulfonic acid and / or a water-soluble salt of the compounds listed.
  • a mixture of at least two of the substances listed above can be used.
  • Polymers based wholly or partly on at least one, in particular at least one, of the abovementioned monomers containing sulfonic acid groups are largely saline-sensitive with respect to their swelling properties in saline water containing saline.
  • the polymers to be used consist of 40 to 90 mol .-% and particularly preferably from 50 to 75 mol .-% of a sulfonic acid group-containing monomer or more sulfonic acid group-containing monomers.
  • polymers containing sulfonic acid group-containing monomers and nonionic monomers are also preferred.
  • nonionic monomers suitable for copolymerization are, for example, methacrylamide, n-alkyl-substituted acrylamides, 2-hydroxyethyl acrylate, 2-hydroxyethyl methacrylate, hydroxypropyl acrylate, hydroxypropyl methacrylate, C 1 -C 4 -alkyl (meth) acrylate, vinyl acetate and preferably acrylamide.
  • the copolymers which can be used according to the invention preferably contain 0 to 75 mol%, preferably 10 to 60 mol% and very particularly preferably 25 to 50 mol% of a nonionic monomer.
  • the polymers are crosslinked.
  • Suitable crosslinking agents are preferably all polyfunctional crosslinking agents. Particularly preferred are crosslinking agents having at least two olefinically unsaturated double bonds.
  • the degree of crosslinking substantially influences the viscosity and thus the adhesive properties of the resulting polymer.
  • At least one residual monomer destroyer is preferably added to the polymers to be used according to the invention.
  • Restmonomerenvernichter in the context of the present invention are substances that modify polymerizable monomers by a chemical reaction such that they are no longer polmerisierbar, so that they no longer represent monomers.
  • substances which react with the double bond contained in the monomers and / or substances which can initiate a further polymerization are examples of substances which react with the double bond contained in the monomers and / or substances which can initiate a further polymerization.
  • Residual monomer destroyers in the sense of the present invention are disclosed in detail in the patent application DE 100 41 395.1, in particular on pages 6 to 7, which is hereby introduced as a reference and thus applies as part of the disclosure.
  • the at least partially sulfonic acid-containing polymers are the saline extinguishing water preferably in an amount of 0.25 to 10 wt .-%, preferably from 0.5 to 5 wt .-%, particularly preferably in an amount of 1 to 3 wt .-% based added to the polymerizate added extinguishing water.
  • the polymers to be used according to the invention are present as water-in-oil polymer dispersion or water-in-water polymer dispersion.
  • Water-in-oil polymer dispersions for the purposes of the present invention and processes for their preparation are described in EP 0 774 279 B1, for example on page 3, lines 3 to 55 and pages 7 to 8, and DE 100 41 395.1, for example on the pages 3 to 5, which are hereby incorporated by reference and thus are considered part of the disclosure.
  • Water-in-oil polymer dispersions consist of a continuous oil phase in which particles of a mostly crosslinked water-swellable polymer are dispersed.
  • the polymer particles usually have particle sizes in the range of 0.1 to 10 microns, preferably less than 2 microns, resulting in extremely short swelling times of less than 3 seconds.
  • these dispersions are prepared by reverse phase emulsion polymerization.
  • Water-in-water polymer dispersions are a class of products made by liquid phase polymerization, for example, by emulsion or suspension polymerization.
  • monomers or a monomer solution are added to an aqueous phase containing at least one dispersant and the resulting mixture is polymerized.
  • the particle sizes of the polymers of these primary dispersions are in the range from 0.05 to 10 .mu.m, preferably in the range from 0.5 to 5 .mu.m, very particularly preferably in the range from 0.5 to 2.
  • Dispersants and their application are, for example, to the first two Paragraphs of page 6 of DE 100 41 394.3 described.
  • Water-in-water polymer dispersions for fire prevention have the advantage that such dispersions are ecologically better on the one hand and on the other hand have less flammable components.
  • water-in-oil and water-in-water polymer dispersions with polymer particle particles whose largest dimension is less than 10 microns, preferably less than 2 microns and more preferably less than 1 micron.
  • the swelling time of such water-swellable polymer dispersions to be used according to the invention is preferably not more than three minutes, more preferably not more than 30 seconds and most preferably not more than 10 seconds.
  • Such polymer dispersions are eminently suitable for use in continuous mixing outlet devices for fire fighting or contraception.
  • polymer dispersions are obtained with electrolyte-containing water (extinguishing water), preferably in a concentration of 0.25 to 10% by volume, preferably 0.5 to 5% by volume and particularly preferably 1 to 3% by volume placed on the polymerized water.
  • electrolyte-containing water preferably in a concentration of 0.25 to 10% by volume, preferably 0.5 to 5% by volume and particularly preferably 1 to 3% by volume placed on the polymerized water.
  • extinguishing water-additive mixtures to be used according to the invention can be applied to the surfaces affected by the fire with any conventional firefighting device.
  • any conventional firefighting device are described, for example, in EP 0 774 279 B1 and in DE 299 04 848 U1, which are hereby incorporated by reference and thus are considered part of the disclosure.
  • the mixing of the additive with the saline extinguishing water preferably takes place continuously in a conventional outlet device for fire fighting.
  • natural saline extinguishing water sources such as brackish water or sea water, for example, in fires on ships and rigs or in ports or on the coast can be used without delay.
  • the additive can also be mixed in batches with the extinguishing water before, as previously shown, applied by an outlet device to a surface, preferably a vertical, inclined or overhanging surface, for fire prevention and / or fire fighting.
  • a 30% by weight solids-containing water-in-oil polymer dispersion of 52 mole% acrylamidopropanesulfonic acid sodium salt and 48 mole% acrylamide having an average particle size in the range of 0.1-10 ⁇ m was dissolved in a 5% and a 10% by weight Concentration based on the mixture mixed with seawater and the viscosities at different shear rate determined with a Brookfield viscometer (20 ° C): 1) 5% by weight in seawater viscosity Spindle I 1 rpm 2,960 mPas Spindle I 2.5 rpm 2,190 mPas Spindle I 5 rpm 1,720 mPas Spindle III 1/50 rpm 760 mPas 2) 10% by weight in seawater viscosity Spindle III 1 rpm 53,600 mPas Spindle III 2.5 rpm 30,400 mPas Spindle IV 5 rpm 20,000 mPas Spindle IV 50 rpm 5,040
