Description

Zum Feuerfestmachen von Holz und Gewe'ben hat man bereits mit Erfolg organische Stoffe verwendet, die sich beim Erhitzen zu einer schaumigen Masse aufblähen,For fireproofing wood and fabric, organic ones have already been used with success Uses substances that expand into a foamy mass when heated,

.5 z.B. Harnstoff-Formaldehyd-Kondensationsprodukte, denen nach Bedarf anorganische Salze oder Farbstoffe zugesetzt werden. Man hat ferner als feuersichere Überzüge ergebende Anstrichmittel eine Mischung von Ammonsalzen mit Dicyandiamid und Formaldehyd, gegebenenfalls mit einem Gehalt an Füllstoffen und Pigmenten, vorgeschlagen..5 e.g. urea-formaldehyde condensation products, to which inorganic Salts or dyes are added. There are also resulting fireproof coatings Paint a mixture of ammonium salts with dicyandiamide and formaldehyde, optionally with a content of fillers and pigments, suggested.

Die vorliegende Erfindung stützt sich auf die Erkenntnis, daß wässerige Lösungen von gegebenenfalls unter Säurezusatz hergestellten Kondensationsprodukten von Dicyandiamid, Dicyandiatnidin, Guanidin, Melamin oder Biguanid bzw. deren Salzen mit Aldehyden, insbesondere Formaldehyd, zum Feuerfestmachen von Holz und Geweben ao durch Oberflächenbehandlung ausgezeichnet geeignet sind, ohne daß es eines -besonderen Zusatzes von verbrennungsverzögernden Salzen bedarf. Die genannten Lösungen lassen sich, besonders nach dem Eindampfen auf geeignete Konzentration, ohne Schwierigkeit auf die zu schützenden Gegenstände auftragen und zeigen beim Trocknen nicht die nachteilige Erscheinung eines Aldehydverlustes. Gegenüber den bekannten Harnstoff-The present invention is based on the finding that aqueous solutions of condensation products of dicyandiamide produced with the addition of acids, if appropriate, Dicyandiatnidine, guanidine, melamine or biguanide or their salts with aldehydes, especially formaldehyde, excellent for making wood and fabrics fireproof by surface treatment are suitable without there being any special addition of combustion retardants Salt needs. The solutions mentioned can be, especially after evaporation Apply to the objects to be protected at a suitable concentration without difficulty and do not show the disadvantageous phenomenon of loss of aldehyde on drying. Compared to the well-known urea

Formaldehyd-Kondensatioiisprodukten zeigen die Feuerschutzmittel gemäß der Erfindung eine wesentlich höhere Wirksamkeit. Vorteilhaft werden erfahrungsgemäß Lösungen ver ■ wendet, die bei der Behandlung der Mutteroder Waschlauge der Dicyandiamidherstellung aus Cyanamid oder Kalkstickstoff mit Aldehyden entstehen. Von den genannten Kondensationsprodukten erwiesen sich solche als ίο besonders brauchbar, die auf ι MoI Dicyandiamid etwa ι Mol Formaldehyd enthalten: die Menge an Formaldehyd kann aber auch höher gewählt werden. Bei der Kondensation wirkt ein geringer Säurezusatz beschleunigend; außerdem kann durch höheren Säurezusatz mehr Dicyandiamidsalz gebildet werden. Eine weitere Steigerung der Feuerschutzwirkung wird durch Verwendung von Lösungen der genannten Kondensationsprodukte erreicht, die unter Zusatz von als Feuerschutzmittel an sich bekannten Säuren, wie z. B. Phosphorsäure oder Borsäure, hergestellt worden sind. Den Lösungen können außer den verbrennungsverzögernden Stoffen noch besondere fäulnishemmende Stoffe zugesetzt werden.Show formaldehyde condensation products the fire protection means according to the invention have a much higher effectiveness. Advantageous experience shows that solutions are used that are used in the treatment of the mother or Wash liquor from dicyandiamide production from cyanamide or calcium cyanamide with Aldehydes are formed. Of the condensation products mentioned, those were found to be ίο particularly useful that based on ι MoI dicyandiamide contain about ι mol of formaldehyde: the amount of formaldehyde can also be chosen higher. A small addition of acid accelerates the condensation; moreover, more dicyandiamide salt can be formed by adding more acid. A further increase in the fire protection effect is achieved by using solutions of the condensation products mentioned, with the addition of as Fire retardants known acids, such as. B. phosphoric acid or boric acid have been. In addition to the combustion-retarding substances, special putrefactive substances can also be added to the solutions will.

Ausführungsbeispiele'Embodiments'

i. 100 kg technisches Dicyandiamid werden in 300 1 Wasser von 75 bis 8o° eingetragen. Xach dem Auflösen werden unter Umrühren 5 1 einer io°/oigen Schwefelsäure und 50 1 handelsübliche Formaldehydlösung (40 Volumprozent) zugegeben. Es bildet sich sofort eine klare Lösung, die 3 Stunden bei 75 bis 8o° gehalten wird. Hierauf erfolgt wiederum eine Zugabe von 5 1 der io°/oigen Schwefelsäure und von 501 Formaldehydlösung. Während des weiteren Eindampfens bei einer mittleren Temperatur von 750 wird von Zeit zu Zeit eine Probe genommen und das spezifische Gewicht der Lösung bei 150 ermittelt. Die Eindampfung wird beendet, sobald das spezifische Gewicht 1,25 bis 1,3 eri. 100 kg of technical dicyandiamide are introduced into 300 liters of water at from 75 to 80 °. After dissolution, 5 liters of 10% sulfuric acid and 50 liters of commercially available formaldehyde solution (40 percent by volume) are added with stirring. A clear solution forms immediately and is kept at 75 to 80 ° for 3 hours. This is again followed by the addition of 5 liters of the 10% sulfuric acid and 50 liters of formaldehyde solution. During the further evaporation at an average temperature of 75 ° , a sample is taken from time to time and the specific gravity of the solution at 15 ° is determined. The evaporation is stopped as soon as the specific gravity is 1.25 to 1.3

reicht ist. Die erhaltene Lösung ändert sich nicht beim Lagern und eignet sich ohne weiteres zum Aufstrich au-f Holz.is enough. The solution obtained does not change on storage and is suitable without it further to the spread on wood.

2. 20 kg Dicyandiamid, 25,7 kg Formaldehyd als handelsübliche 40°/oige Lösung. kg Wasser und 0,37 kg konzentrierte Salzsäure werden 1V2 Stunden auf 90 bis 100" erhitzt. Xach der Abkühlung werden 2$ß kg H3 P O4 in Form von 85 %iger Phosphorsäure zugefügt. Das so erhaltene Feuerschutzmittel wird so sparsam auf das zu behandelnde Gewebe aufgebracht, daß möglichst keine überschüssige Menge sichtbar ist, was bei einem einmaligen Aufbringen beispielsweise einem Feuerschutzmittelverbrauch um 300 g/m- entsprechen kann. Das aufgebrachte Mittel bildet an der Faser eine festhaftende Schicht und setzt die Brennbarkeit des Gewebes stark herab.2. 20 kg of dicyandiamide, 25.7 kg of formaldehyde as a commercial 40% solution. kg of water and 0.37 kg of concentrated hydrochloric acid are heated to 90 to 100 "for 1 1/2 hours. After cooling, 2 3 kg of H 3 PO 4 in the form of 85 % phosphoric acid are added The treated fabric is applied so that as little excess amount is visible as possible, which with a single application can, for example, correspond to a fire protection agent consumption of around 300 g / m- The applied agent forms a firmly adhering layer on the fiber and greatly reduces the flammability of the fabric.
