Description

Verfahren zur Behandlung brennbarer Stoffe Die Verwendung von verbrennungsverzögernden Salzen, z. B. phosphorsauren Salzen, zum Imprägnieren brennbarer Stoffe ist bekannt. Es besteht jedoch hierbei der Nachteil, daß diese Salze nach der Imprägnierung auskristallisieren und somit im Laufe der Zeit oder schon bei der Verarbeitung des so imprägnierten Materials leicht von diesem abfallen.Method of treating combustible materials The use of combustion retardants Salts, e.g. B. phosphoric acid salts, for impregnating flammable substances is known. However, there is the disadvantage that these salts crystallize out after impregnation and thus over time or during the processing of the impregnated Material easily fall off from this.

llan hat, um diesen Nachteil zu beseitigen, schon verschiedene Vorschläge gemacht, beispielsweise Lösungen von Natriumchlorid in Wasserglas zum Imprägnieren von Holz verwandt, desgleichen Ammonium- und Magnesiumverbindungen gemeinsam mit Trioxvmetlivlen. Ferner hat man zum Feuersichermachen von Stroh u. dgl. nach dem Aufschließen der Pflanzenschale mit silikatlösenden Mitteln, wie Natronlauge, diese Stoffe mit feuersichermachenden Stoffen, wie Arnmonsulfat und Borax, zusammen finit Klebstoffen. wie Stärke, behandelt. Ein sicherer Schutz wird jedoch durch diese Kombinationen nicht erzielt, cla z. B. die Kombination L\Tatriumchlorid-Wasserglas nicht fest genug auf dein Holz haftet, Trioxvmethylen weder die Kristallisation hemmt, noch die Haftfestigkeit beeinflußt und auch eine Imprägnierung mit Aminonsulfat, Borax und Stärke sich im Feuer leicht vom Holz ablöst.llan already has various proposals to remedy this disadvantage made, for example, solutions of sodium chloride in water glass for impregnation related to wood, as well as ammonium and magnesium compounds together with Trioxvmetlivlen. Furthermore, you have to make straw and the like after the fire Unlocking the plant shell with silicate dissolving agents, such as caustic soda, these Substances with fire retardant substances such as ammonium sulphate and borax, together finite Adhesives. like strength, treated. A more secure protection is however through this Combinations not achieved, cla z. B. the combination of sodium chloride and water glass does not adhere firmly enough to your wood, neither does Trioxvmethylene crystallize inhibits, nor affects the adhesive strength and also impregnation with aminone sulfate, Borax and starch easily separate from the wood in a fire.

Es wurde nun die im Hinblick auf die hohe Bedeutung eines sicheren Feuerschutzes sehr wichtige Beobachtung gemacht, daß man die genannten Nachteile vermeiden kann, wenn man die brennbaren Stoffe mit Lösungen bzw. Suspensionen wasserlöslicher, verbrennungsverzögernder Salze, z. B. Ammoniumphosphat, in Lösungen von Harnstoff-Formaldehvd-Kondensationsprodukten behandelt. Es können hierbei auch beliebige Gemische von verbrennungsverzögernden Salzen angewandt werden.It has now been made in view of the great importance of a safe Fire protection made very important observation that one has the disadvantages mentioned can be avoided if the flammable substances are mixed with solutions or suspensions of water-soluble, combustion retardant salts, e.g. B. ammonium phosphate, in solutions of urea-formaldehyde condensation products treated. Any mixtures of combustion retardants can also be used here Salts are applied.

Diese Art der Imprägnierung bietet den Vorteil, daß sie vollkommen fest an der Unterlage haftet, das Auskristallisieren der die Verbrennung verzögernden Salze verhindert und neben einer wesentlichen Verminderung der Entflammbarkeit bzw. Brennbarkeit dem Holz usw. eine erhöhte Widerstandsfähigkeit gegen die Verminderung der statischen Festigkeit verleiht. Besonders vorteilhaft ist auch der Fortfall von Nachglianm-undFunkenflugerscheintingen bei Anwendung des neuen Imprägniermittels. Die mit diesem erzeugte Isolierschicht schmilzt im Feuer zunächst und bläht sich auf, blättert aber nicht ab und schützt somit das Holz lange Zeit vor der Einwirkung der heißen Flammengase. Ein gewisser Feuerschutz wird schon durch bloßes Anstreichen der zu schützenden Gegenstiinde erzielt, es ist jedoch in vielen Fällen zweckni<ißig, das Eindringen des Feuerschutzmittels in diese Gegenstände durch abwechselnde Anwendung von =vermindertem und erhöhtem Druck zu unterstützen. Beispiel i i cbm Kantholz wird in eine Harnstoff-Formaldehyd-Lösung mit 300/6 Trockensubstanz und einem Gehalt an Diammoniumphosphat von 2o°/" eingetaucht und hierin 2 Stunden unter Vakuum und q. Stunden unter Druck gehalten. Nach dem Entfernen der überschüssigen Lösung wird das. Holz getrocknet. Die Gewichtszunahme beträgt io bis 15 °/o. Das Imprägniermittel haftet außerordentlich-fest auch bei starkerBeanspruchung des Materials. Die Entflammbarkeit und Brennbarkeit des so behandelten Holzes sind bedeutend herabgesetzt.This type of impregnation has the advantage that it adheres firmly to the substrate, prevents the salts that retard the combustion from crystallizing and, in addition to a significant reduction in flammability or combustibility, gives the wood, etc., increased resistance to the reduction in static strength. The elimination of flashiness and flying sparks when using the new impregnating agent is also particularly advantageous. The insulating layer created with this initially melts in the fire and puffs up, but does not flake off and thus protects the wood from the effects of the hot flame gases for a long time. A certain degree of fire protection is achieved by simply painting the objects to be protected, but in many cases it is useful to support the penetration of the fire protection agent into these objects by alternately applying reduced and increased pressure. Example ii cbm square timber is immersed in a urea-formaldehyde solution with 300/6 dry matter and a diammonium phosphate content of 20 ° / "and kept in it for 2 hours under vacuum and q hours under pressure . wood dried. the weight gain is io 5 to 1 ° / o. the impregnating extremely-firmly adhered even in starkerBeanspruchung of the material. the flammability and combustibility of the wood thus treated are significantly reduced.

Beispie12 TextilgeNvebe wird in eine Lösung mit einem Gehalt von 20°/" Diaminoniuinphosphat und 2 % Harnstoff-Formaldehyd-Lösung getaucht. Nach dem Abschleudern der Überschüssigen Lösung erfolgt die Trocktinng. Das Imprägniermittel haftet sehr fest u»d setzt die Brennbarkeit des Gewebes starb herab. Beispiel 3 Eine Lösung von 2o kg Dimethylolliarnstoff und 6o kg Diammoniumphosphat in ioo Liter Wasser wird, gegebenenfalls unter Zusatz von Säure, erwärmt. Mit der erhaltenen Lösung wird das zu imprägnierende l lolz nach einem der üblichen Verfahren behandelt.Example 12 Textile fabric is poured into a solution with a content of 20 ° / " Immersed diaminonine phosphate and 2% urea-formaldehyde solution. After being thrown off the excess solution is dried. The impregnation agent is very adhesive fixed and reduced the flammability of the tissue. Example 3 One solution of 20 kg of dimethyl sulphide and 60 kg of diammonium phosphate in 100 liters of water is heated, optionally with the addition of acid. With the solution obtained the wood to be impregnated is treated according to one of the usual methods.
