Description
Mittel, insbesondere zur Brandbekämpfung und Imprägnierung . Agents, in particular for fire fighting and impregnation.
Die Erfindung betrifft ein Mittel, insbesondere zur Brandbekämpfung und Imprägnierung, bestehend aus einer wässerigen Lösung, die ein oder mehrere nichtionische Tenside in einer Konzentration von 0,02 bis 0,2 Volumen¬ prozent aufweist, sowie ein Verfahren zu dessen Herstel¬ lung.The invention relates to an agent, in particular for fire fighting and impregnation, consisting of an aqueous solution which has one or more nonionic surfactants in a concentration of 0.02 to 0.2 percent by volume, and a method for the production thereof.
Brandbekämpfungslösungen solcher Art sind bekannt (DE- 0S 31 00 158). Dabei werden als grenzfl chenaktive Mittel in erster Linie solche verwendet, die durch Kondensation von Äthylenoxid oder Propylenoxid mit verschiedenen Substanzen und insbesondere mit phenollo¬ schen Verbindungen mit einer Seitenkette erhältlich sind. Kombinationen aus einem oder mehreren nichtioni¬ schen grenzflächenaktiven Mitteln werden zur Erzielung einer Wasserlöslichkeit innerhalb eines 20-100°C-Trü- bungspunktbereiches ausgewählt, um eine möglichst geringe Schaummenge zu erzeugen.
Demgegenüber liegt der Erfindung die Aufgabe zugrunde, ein fein sprühbares Stoffgemisch mit hohem Imprägnierver¬ mögen zu schaffen, das gleichzeitig biologisch leicht abbaubar und nicht toxisch ist. Diese Aufgabe wird dadurch gelöst, daß als Tensid Alkylarylsulfonat verwendet wird.Fire fighting solutions of this type are known (DE-0S 31 00 158). In this case, be used as a boundary-active agents are primarily those that are obtainable by condensation of ethylene oxide or propylene oxide with various substances and in particular with phenoll o ¬ rule compounds having a side chain. Combinations of one or more nonionic surface-active agents are selected in order to achieve water solubility within a 20-100 ° C. cloud point range in order to produce the smallest possible amount of foam. In contrast, the object of the invention is to create a finely sprayable mixture of substances with a high impregnation capacity which at the same time is readily biodegradable and non-toxic. This object is achieved in that alkylarylsulfonate is used as the surfactant.
Alkylarylsulfonate (R-Ar-S03-Me) waren bisher hauptsächl ch als Rohstoffe für synthetische Waschmittel bekannt. Sie besitzen gutes Emolgier-, Enfettungs- und Netzvermögen sowie eine hohe chemische Beständigkeit. Aufgrund Ihrer in der Regel unverzweigten Verbindungen sind sie biolo¬ gisch gut abbaubar. Ihre Toxidität gegenüber Fischen beruht allein darauf, daß sie die Oberflächenspannung des Wassers stark erniedrigen.Until now, alkylarylsulfonates (R-Ar-S0 3 -Me) were mainly known as raw materials for synthetic detergents. They have good evolving, degreasing and wetting properties as well as a high chemical resistance. Because of their generally unbranched compounds, they are readily biodegradable. Their toxicity to fish is based solely on the fact that they significantly lower the surface tension of the water.
Das erfinduπgsgemäße Mittel bzw. Stoffgemisch läßt sich insbesondere zur Brandlöschung bzw. -Verhütung vorteilhaft einsetzen, da aufgrund der wesentlichen Verminderung der Oberfl chenspannung durch Alkylarylsulfo¬ nat die Verteilung der einzelnen Lδschtropfen an der Sprühdüse des Löschgeräts viel feiner wird. Gleichzeitig wird die Oberfl che des zu versprühenden Löschmittels
The agent or substance mixture according to the invention can be used advantageously in particular for fire extinguishing or prevention, since the distribution of the individual drops of extinguishing agent at the spray nozzle of the extinguishing device becomes much finer due to the substantial reduction in the surface tension due to alkylarylsulfonate. At the same time, the surface of the extinguishing agent to be sprayed
um ein Vielfaches vergrößert. Indem man dem Löschmittel Alkylarylsulfonat als Netzmittel beimischt, werden bei der Brandlöschung so schwer löschbare Stoffe wie Stroh, Heu, Wollballen, Fertigtextilien, Pulver usw., die oft kompliziert strukturierte Oberfläche aufweisen, unter Verdrängung der Luft benetzt, sozusagen gründlich "durchtränkt". Dies führt zu einer erheblichen Erleich¬ terung und Beschleunigung des Löschens.magnified many times over. By adding alkylarylsulfonate as a wetting agent to the extinguishing agent, fire-extinguishing substances such as straw, hay, bales of wool, finished textiles, powders, etc., which often have a complicated structured surface, are wetted, so to speak, thoroughly "soaked", so to speak. This leads to a considerable easing and acceleration of the deletion.
Um das Ausfällen von Inertstoffen zu verhindern, wird gemäß einer weiteren vorteilhaften Ausbildung der Erfin¬ dung im Löschmittel eine leicht saure Umgebung mit einem pH-Wert von 6,5 aufgebaut. Hierzu wird 30%ige Essigsäure (CH--C00H) in einer Konzentration von 0,2 Volumenprozent zusammen mit zwei Volumenprozent destillier¬ tem Wasser zu einer Lösung angesetzt. Diese Pufferlösung reduziert überdies die Gefahr einer Schaumbildung, die bei Zugabe von Tensiden unumgänglich ist.In order to prevent the precipitation of inert substances, according to a further advantageous embodiment of the invention in the extinguishing agent, a slightly acidic environment with a pH of 6.5 is built up. For this purpose, 30% acetic acid (CH-C00H) in a concentration of 0.2 percent by volume is mixed with two percent by volume of distilled water to form a solution. This buffer solution also reduces the risk of foam formation, which is unavoidable when tensides are added.
Um die Gefahr der Schaumbildung weiter zu vermindern, wird gemäß einer weiteren Ausbildung der Anteil des Alkylarylsulfonats im Löschmittel auf etwa 0.09 Volumen¬ prozent begrenzt. In der Praxis konnte bei einer solchen
In order to further reduce the risk of foam formation, the proportion of alkylarylsulfonate in the extinguishing agent is limited to about 0.09 percent by volume. In practice, such
Konzentration dieses Tensids die Oberfl chenspannung um ca. 60 % reduziert werden, ohne daß eine Ausfällung der Inertstoffe auch nach längerer Standzeit (z.B. 3 Wochen) auftrat.Concentration of this surfactant, the surface tension can be reduced by approx. 60%, without precipitation of the inert substances occurring even after a long standing time (e.g. 3 weeks).
Gemäß einer weiteren Ausbildung der Erfindung wird als Löschmittel eine wässerige Lösung mit Alkalimetall¬ citrat und/oder Sulfaten bis zur Sättigungskonzentra¬ tion verwendet. Diese Lösung ist farblos, klar, neutral riechend und viskos. Mit Alkal metallcitrat läßt sich bereits eine prophylaktische Imprägnierung des Brand¬ umfeldes und/oder eine generelle Imprägnierung verschie¬ denster, leicht entflammbarer Materialien erreichen, die dadurch weitgehend feuerfest werden. Durch Zugabe von bzw. Kombination mit Alkylarylsulfonat wird die Imprägnierwirkung dann noch weiter optimiert.According to a further embodiment of the invention, an aqueous solution with alkali metal citrate and / or sulfates up to the saturation concentration is used as the extinguishing agent. This solution is colorless, clear, neutral smelling and viscous. With alkali metal citrate, a prophylactic impregnation of the fire environment and / or a general impregnation of various, easily flammable materials can be achieved, which thereby become largely fire-resistant. The impregnation effect is then further optimized by adding or combining with alkylarylsulfonate.
Eine weitere grundlegende Anforderung an Mittel zum Feuerlöschen besteht in der Sicherheit vor Gefrieren bei Temperaturen bis mindestens -30°C. Da das im wesent¬ lichen aus Al alimetallcitrat bestehende Löschmittel aufgrund der konzentrierten Lösung aliphatischer Salze einen hohen Sättigungsgrad aufweist, ist es an sich bereits bis -15°C frostfest. Gemäß einer besonders vorteilhaften Ausbildung wird dem erfindungsgemäßen
Another basic requirement for fire extinguishing agents is the protection against freezing at temperatures down to at least -30 ° C. Since the extinguishing agent consisting essentially of aluminum metal citrate has a high degree of saturation due to the concentrated solution of aliphatic salts, it is inherently frost-resistant down to -15 ° C. According to a particularly advantageous embodiment of the invention
Stoffge isch 1,2-Äthandiol hinzugegeben. Da eine Lösung von einem Teil Wasser und einem Teil 1 ,2-Äthandiol erst bei -40°C gefriert, und in der praktischen Anwendung die freien Wassermoleküle in der wässrigen Lösung mit Alkalimetallcitrat mit 1 ,2-Äthandiol ebenfalls im Verhält¬ nis 1:1 gemischt sind, ist mit dem erfindungsgemäßen Mittel eine Sicherheit vor Gefrieren jedenfalls bis -30°C gewährleistet. Zusätzliche Vorteile durch die Anwendung von 1 ,2-Äthandiol als Gefrierschutz ergeben sich aus dessen Kostengünstigkeit, relativer Umweltverträg¬ lichkeit und einer Vermeidung einer sofortigen Übersätti¬ gung des erfindungsgemäßen Stoffgemisches.Stoffge isch 1,2-ethanediol added. Since a solution of a part of water and a part of 1,2-ethanediol only freezes at -40 ° C, and in practical use the free water molecules in the aqueous solution with alkali metal citrate with 1,2-ethanediol also in a ratio of 1: 1 are mixed, the agent according to the invention guarantees security against freezing in any case down to -30 ° C. Additional advantages from the use of 1,2-ethanediol as anti-freeze result from its cost-effectiveness, relative environmental compatibility and the avoidance of immediate oversaturation of the mixture of substances according to the invention.
Im Ergebnis führt die Anwendung des erfindungsgemäßen Mittels bei der Brandbekämpfung zu einer Verringerung des Löschmittelbedarfes, einer Verbreiterung des Sprühne¬ bels und einer Verdichtung des Sprühvorhanges beim Austritt aus der Sprühdüse des Löschgeräts, was es vor allem zur Bekämpfung von Bränden der Klassen A und B befähigt. Durch die verstärkte Imprägniertiefe bei porösen Stoffen kann das erfindungsgemäße Mittel insbesondere Brände mit starker Glutnestbildung eindämmen.As a result, the use of the agent according to the invention in firefighting leads to a reduction in the extinguishing agent requirement, a widening of the spray mist and a densification of the spray curtain when it emerges from the spray nozzle of the extinguishing device, which enables it in particular to fight class A and B fires . Due to the increased impregnation depth in the case of porous substances, the agent according to the invention can in particular contain fires with a strong formation of embers.
