Description

Verfahren zum Feuersichermachen von Stroh oder von Schilfrohr. Die gleichzeitige Einwirkung von silikatlösenden Mitteln neben Flammenschutzmitteln auf Pflanzenteile ist bekannt. Dadurch ist es jedoch nicht gelungen, Pflanzenteile, insbesondere Stroh für Dachbedeckung, wirksam feuersicher zu machen. Die Ursache davon ist darin zu suchen, daß die Imprägnierung mit Feuerschutzmitteln vor der Aufschließung der Pflanzenschale nicht oder nur ungenügend gelingen kann. Dazu gesellt sich auch der Umstand, daß, wenn das eine Mittel basisch und das andere sauer ist, diese beiden Mittel einander neutralisieren, daher bei gleichzeitiger Verwendung unwirksam werden.Method for making straw or reeds fire-proof. the simultaneous action of silicate-dissolving agents in addition to flame retardants on parts of plants is known. As a result, however, it was not possible to find parts of plants, especially thatch for roofing, to effectively make fire-proof. The cause of which is to be sought in that the impregnation with fire retardants before the Unlocking the plant bowl can not or only insufficiently succeed. Joined it the fact that if one agent is basic and the other acidic, these two agents neutralize each other, hence when used at the same time become ineffective.

Erfindungsgemäß erfolgt die Einwirkung des Feuerschutzmittels nach einer vorangehenden Aufschließung der Pflanzenschale. Zu diesem Zwecke wird das Stroh oder das Rohr in einem silikatlösenden Mittel, wie in verdünnter Natronlauge, in einer Sodalösung o. dgl. aufgekocht, was am zweckmäßigsten in Autoklaven erfolgen kann. Nach dieser vorbereitenden Behandlung wird die Sättigung mit Feuerschutzmitteln zufriedenstellend erfolgen.According to the invention, the action of the fire protection agent takes place after a previous breakdown of the plant bowl. For this purpose the Straw or the pipe in a silicate dissolving agent, such as in dilute caustic soda, Boiled in a soda solution or the like, which is most conveniently done in an autoclave can. After this preparatory treatment, the saturation with fire retardants becomes done satisfactorily.

Eine zweckmäßige Zusammensetzung des Flammenschutzbades sei hier beispielsweise angeführt 86 Gewichtsteile Wasser, 1o - Ammonsulfat, 2 - Borax und 2 - Stärke. Die Imprägnierung mit dem Feuerschutzmittel kann in heizbaren offenen Gefäßen oder zweckmäßiger in Autoklaven durchgeführt werden.An expedient composition of the flame protection bath is given here, for example 86 parts by weight of water, 1o - ammonium sulfate, 2 - borax and 2 - strength. The impregnation with the fire protection agent can be carried out in heatable open vessels or, more appropriately, in autoclaves.
