Description
Verfahren zur Herstellung von nichtbrennbaren Papieren, Pappen u. dgl. Es wurde gefunden, daß man Papiere, Pappen u. dgl. sowie aus diesen hergestellte Gegenstände in sehr einfacher Weise dadurch nicht brennbar machen kann, daß man sie mit wäßrigen Lösungen oder Dispersionen von Ammoniumsalzen, beispielsweise Diammoniumphosphat oder Ammoniumsulfat, oder von Harnstoff oder Thioharnstoff oder von mehreren dieser und außerdem mit wäßrigen Dispersionen von Polymerisaten des Vinyl- oder Vinylidenchlorids oder diese enthaltenden Mischpolymerisaten behandelt. Selbst dickere Papiere und Pappen verlieren hierbei ihre Brennbarkeit.Process for the production of non-combustible paper, cardboard and the like. It has been found that papers, cardboards and the like can be produced from them Objects can be made non-flammable in a very simple way that one they with aqueous solutions or dispersions of ammonium salts, for example diammonium phosphate or ammonium sulfate, or from urea or thiourea or from more of these and also with aqueous dispersions of polymers of vinyl or vinylidene chloride or treated copolymers containing these. Even thicker papers and Cardboard loses its flammability.
Man arbeitet vorteilhaft so, daß man das Papier bzw. die Pappe zuerst mit einer Lösung eines Ammoniumsalzes oder Harnstoffs oder beider imprägniert, dann trocknet und danach eine wäßrige Dispersion des Polymerisats oder Mischpolymerisats von Vinyl- oder Vinylidenchlorid aufbringt und abermals trocknet. In manchen Fällen genügt aber auch ein einfaches Aufbringen einer wäßrigen Dispersion des Polymerisats oder Mischpolymerisats von Vinyl-oder Vinylidenchlorid, der Ammoniumsalze oder Harnstoffe oder beide zugesetzt sind. und nachfolgendes Trocknen.It is advantageous to work in such a way that the paper or cardboard is first impregnated with a solution of an ammonium salt or urea, or both, then dries and then an aqueous dispersion of the polymer or copolymer of vinyl or vinylidene chloride applies and dries again. In some cases however, a simple application of an aqueous dispersion of the polymer is also sufficient or mixed polymer of vinyl or vinylidene chloride, the ammonium salts or ureas or both are added. and subsequent drying.
Es ist zwar bereits bekannt, Papier mit Lösungen von Harnstoff in Verbindung mit feuerhemmenden Verbindungen, wie Salzen organischer oder schwacher anorganischer Säuren, zu imprägnieren. Diese Verbindungen müssen in hoher Konzentration verwendet werden, wenn das Papier eine ausreichende Flammfestigkeit erhalten soll. Hierdurch wird aber die mechanische Festigkeit des Papiers stark herabgesetzt. Dieser Nachteil wird durch das beanspruchte Verfahren vermieden. Hierbei besitzen Papiere bzw. Pappen eine sehr gute mechanische Festigkeit.Although it is already known to use solutions of urea in paper Connection with fire retardant compounds, such as organic or weak salts inorganic acids, to be impregnated. These compounds need to be in high concentration can be used when the paper is to be given sufficient flame resistance. However, this greatly reduces the mechanical strength of the paper. This The claimed method avoids the disadvantage. Own papers here or cardboard has very good mechanical strength.
Es ist auch bekannt, wachsartige chlorierte Verbindungen, insbesondere chloriertes Naphthalin oder Diphenyl in Verbindung mit Polyvinylchlorid zum Imprägnieren zu verwenden. Es ist aber nicht möglich, aus einem Polymerisat des Vinyl- oder Vinylidenchlorids und den genannten wachsartigen chlorierten Verbindungen homogene wäßrige Dispersionen herzustellen. Imprägniert man Papier zunächst mit einer der wachsartigen Verbindungen und versucht anschließend, die wäßrige Polymerisatdispersion aufzubringen, so haftet das Polymerisat nicht auf dem mit den wachsähnlichen Verbindungen imprägnierten Papier.It is also known to use waxy chlorinated compounds, in particular chlorinated naphthalene or diphenyl in combination with polyvinyl chloride for impregnation to use. But it is not possible from a polymer of vinyl or vinylidene chloride and the waxy chlorinated compounds mentioned, homogeneous aqueous dispersions to manufacture. First of all, paper is impregnated with one of the waxy compounds and then tries to apply the aqueous polymer dispersion, so adheres the polymer is not impregnated with the wax-like compounds Paper.
Schließlich ist bereits beschrieben worden, Gewebe mit einem wasserlöslichen Phosphat, Harnstoff und einem Mischpolymerisat des Vinylchlorids oder Polyvinylchlorid zu imprägnieren. Die so imprägnierten Gewebe werden auf 135 bis 200° erhitzt und anschließend mit Wasser gewaschen, um die nicht umgesetzten Anteile zu entfernen. Es ist unmöglich, dieses Verfahren auf das Flammfestmachen von Papier zu übertragen, weil dieses durch eine solche Behandlung nach dem Imprägnieren unbrauchbar würde.Finally, it has already been described, fabric with a water-soluble Phosphate, urea and a copolymer of vinyl chloride or polyvinyl chloride to impregnate. The fabric impregnated in this way is heated to 135 to 200 ° and then washed with water in order to remove the unreacted components. It is impossible to apply this technique to making paper flame retardant, because this would be unusable by such a treatment after impregnation.
Die in den nachstehenden Beispielen angegebenen Teile sind Gewichtsteile.The parts given in the examples below are parts by weight.
Beispiel 1 Ein 70 g/qm schweres Natronsackpapier wird mit der 15%igen Lösung eines Gemisches von 90 Teilen Ammoniumsulfat und 10 Teilen Harnstoff imprägniert. Die Trocknung erfolgt bei Zimmertemperatur oder bei einer erhöhten Temperatur bis 90°. Nach der Trocknung wird das Papier mit einer wäßrigen Dispersion eines Mischpolymerisates, bestehend aus 90 Teilen Vinylidenchlorid und 10 Teilen Acrylsäurebutylester, in der üblichen Weise beschichtet.Example 1 A 70 g / m 2 heavy soda sack paper is mixed with the 15% strength Impregnated solution of a mixture of 90 parts of ammonium sulfate and 10 parts of urea. Drying takes place at room temperature or at an elevated temperature up to 90 °. After drying, the paper is treated with an aqueous dispersion of a copolymer, consisting of 90 parts of vinylidene chloride and 10 parts of butyl acrylate, in coated in the usual way.
Beispiel 2 Ein 90 g/qm schweres Natronsackpapier wird mit einer 8%igen wäßrigen Lösung von 100 Teilen Diammoniumphosphat imprägniert. Nach dem Trocknen wird das Papier mit einer wäßrigen Dispersion eines Mischpolymerisates der im Beispiel 1 angeführten Zusammensetzung, in welcher zuvor 5% Diammoniumphosphat gelöst sind, in üblicher Weise beschichtet.Example 2 Sack soda paper weighing 90 g / m² is mixed with an 8% strength impregnated aqueous solution of 100 parts of diammonium phosphate. After drying is the paper with an aqueous dispersion of a copolymer in the example 1 composition, in which 5% diammonium phosphate is previously dissolved, coated in the usual way.
Beispiel 3 Ein 40 g/qm schweres Pergaminpapier wird mit einer wäßrigen Dispersion eines Mischpolymerisates der im Beispiel 1 angeführten Zusammensetzung, in welcher zuvor 10% eines Gemisches von 90 Teilen Ammoniumsulfat und 10 Teilen Harnstoff gelöst sind, in der üblichen Weise beschichtet. Beispiel 4 Natronsackpapier vom Gewicht 60 g/qm wird mit 100 Teilen einer wäßrigen Dispersion, deren Festprodukt aus 90% Vinylchlorid und 10% Acrylsäurebutylester besteht und der 10 Teile Ammoniumsulfat zugesetzt sind, so bestrichen, daß ein Auftrag von 33 g Festsubstanz pro qm auf dem Papier erreicht wird. Das so behandelte Papier brennt nur in der Fremdflamme; nach Entfernung der Flamme brennt das Papier nicht weiter.Example 3 A 40 g / m 2 heavy glassine paper is mixed with an aqueous Dispersion of a copolymer those listed in Example 1 Composition in which previously 10% of a mixture of 90 parts of ammonium sulfate and 10 parts of urea are dissolved, coated in the usual way. example 4 soda sack paper weighing 60 g / sqm is mixed with 100 parts of an aqueous dispersion, whose solid product consists of 90% vinyl chloride and 10% butyl acrylate and to which 10 parts of ammonium sulfate are added, coated so that an application of 33 g solids per square meter on the paper is achieved. The paper treated in this way burns only in the foreign flame; after removing the flame, the paper does not continue to burn.
