Abstract
Description
In Weiterbildung der Erfindung dient als Lösungsmittel für die Borsäure ein primäres, ein sekundäres, ein tertiäres Amin und/oder als Polyamin ein Diamin, Triamin, Tetramin oder Pentamin. In a further development of the invention, the boric acid is used as a solvent a primary, a secondary, a tertiary amine and / or as a polyamine a diamine, Triamine, tetramine or pentamine.
Durch die Erfindung ist ein viskoses, flüssiges, hochkonzentriertes Holz- und Flammenschutzkonzentrat mit einem Gehalt von über 500/o Borsäure geschaffen, das in jedem Verhältnis mit Wasser zu einem Holz- und Flammenschutzmittel mischbar ist. Die Löslichkeit ist oberhalb von 0° C nahezu temperaturunabhängig. Die Borverbindungen kristallisieren nach dem Verdampfen des Wassers nicht aus, sondern werden immer viskoser, bis die allmählich wie Glas erhärten. Through the invention is a viscous, liquid, highly concentrated Wood and flame protection concentrate with a content of over 500 / o boric acid created, which can be mixed with water in any ratio to form a wood and flame retardant is. The solubility is almost independent of temperature above 0 ° C. The boron compounds do not crystallize after the water has evaporated, but always will more viscous, until they gradually harden like glass.
Bei den meisten Aminen genügt ein Einrühren der Borsäure in die Amine. Da die erhaltenen Flüssigkeiten jedoch zu viskos sein können, kann bei der Verarbeitung eine geringe Wasserzugabe empfehlenswert sein. With most amines, it is sufficient to stir the boric acid into the amines. However, since the liquids obtained can be too viscous, they can be processed during processing a small addition of water can be recommended.
Das Konzentrat läßt sich oberhalb eines pH-Wertes von etwa 6,5 bis 7,5 leicht herstellen. Unterhalb dieser pH-Werte wird das Lösen der Borsäure in den Aminen oder Polyaminen erschwert. Ein pH-Wert von etwa 7,5 bis 8,0 entspricht einem Mischungsverhältnis von etwa 1 Mol Amin zu 3 bis 4 Mol Borsäure. Bei den Polyaminen muß jeweils etwa 1 Stickstoffatom des Polyaminmoleküls mit 3 Mol Borsäure reagieren, d. h., es ergibt sich z. B. das Mischungsverhältnis von 1 Mol Triamin zu 9 Mol Borsäure. Durch Erhöhen des Amin- oder Polyaminanteiles lassen sich höhere pH-Werte beliebig einstellen.The concentrate can be above a pH of about 6.5 to 7.5 easy to manufacture. Below these pH values, the boric acid dissolves in the amines or polyamines difficult. A pH of around 7.5 to 8.0 corresponds to this a mixing ratio of about 1 mole of amine to 3 to 4 moles of boric acid. With the polyamines about 1 nitrogen atom of the polyamine molecule must react with 3 moles of boric acid, d. that is, it results e.g. B. the mixing ratio of 1 mole of triamine to 9 moles of boric acid. By increasing the proportion of amine or polyamine, higher pH values can be achieved at will to adjust.

The wood and manufactured with the concentrate according to the invention Flame retardants can also be used as paints. After painting or spraying on wood or other objects to be protected forms a varnish-like Coating that expands when exposed to a flame and a flame-retardant porous boric anhydride carbon layer can arise.
Durch Zusätze geeigneter Pigmente, z. B. Titandioxid, lassen sich gefärbte Flammenschutzanstriche herstellen. By adding suitable pigments, e.g. B. titanium dioxide, can Manufacture colored flame retardant coatings.
Durch Einarbeiten von z. B. Vermiculit kann das Aufblähen und damit die Flammenschutzwirkung weiter verbessert werden. By incorporating z. B. Vermiculite can cause puffing and thus the flame protection effect can be further improved.
