Description
Im Patent 1126 233 wird ein Verfahren zur Herstellung eines in Wasser innerhalb kürzester Zeit in seine Bestandteile zerfallenden beschreib- und bedruckbaren Papiers durch Zersetzen von Füll- und wasserlöslichen Bindemitteln üblicher Art zum Papiergrundstoff beschrieben. Es ist dadurch gekennzeichnet, daß man ein trockenes Faservlies mit einer wäßrigen Mischung aus Füllstoffen und wasserlöslichen Bindemitteln derart imprägniert, daß pro 100 Teile Fasern etwa 40 bis 200 Teile Bindemittel und eine ebenso große Menge Füllstoff aufgenommen werden, anschließend trocknet und nach einem Wiederanfeuchten bis auf einen Feuchtigkeitsgehalt von etwa 3 bis 10% bei einer Temperatur zwischen 50 und 2000C kalandriert.The patent 1126 233 describes a process for the production of a writable and printable paper that disintegrates into its constituent parts within a very short time by decomposing fillers and water-soluble binders of the usual type to form the paper base. It is characterized in that a dry fiber fleece is impregnated with an aqueous mixture of fillers and water-soluble binders in such a way that about 40 to 200 parts of binder and an equally large amount of filler are absorbed per 100 parts of fibers, then dried and, after rewetting, up to calendering a moisture content of about 3 to 10% at a temperature between 50 and 200 0 C.
Das so hergestellte Material löst sich zwar nach kurzer Zeit in Wasser in seine Bestandteile auf, zeigt aber den Nachteil gegenüber normalem Papier, daß es schwer brennbar ist, da der hohe Gehalt an organischen Füllstoffen die Verbrennung der organischen Bestandteile, wie Fasern und Bindemittel, sehr erschwert. The material produced in this way dissolves into its components after a short time in water, shows but the disadvantage compared to normal paper that it is difficult to burn because of the high organic content Fillers make the combustion of organic components, such as fibers and binders, very difficult.
Es wurde nun gefunden, daß man ein wasserlösliches und sehr gut brennbares bzw. verkohlendes Papier erhalten kann, wenn man der nach obigem Verfahren verwendeten Tränkmischung mit den Bindemitteln und Füllstoffen sauerstoff abgebende und die Verbrennung fördernde Substanzen, wie Salpeter (Kalium-Natrium-Ammonium-Calcium-Nitrat) und/ oder Kalium-Natrium-Chlorat und -Perchlorat, Natriumperborat und andere Persalze und/oder Nitrozellulosen (Collodiumwollen, Lackwollen, Schießwollen) zusetzt und ein geeignetes Faservlies mit diesen Substanzen imprägniert und trocknet und das erhaltene Material nach Wiederbefeuchtung durch Kalandern glättet.It has now been found that a water-soluble and very easily combustible or charring Paper can be obtained if the impregnation mixture used in the above process with the Binding agents and fillers, substances that release oxygen and promote combustion, such as saltpetre (Potassium-sodium-ammonium-calcium-nitrate) and / or potassium-sodium-chlorate and perchlorate, sodium perborate and other persalts and / or nitrocelluloses (collodion wool, lacquer wool, gunwool) adds and impregnates a suitable fiber fleece with these substances and dries and that material obtained after remoistening is smoothed by calendering.
Man erhält Papiere jeden gewünschten Gewichts von 30 bis 150 g/m2, die in bekannter Weise beschreibbar sind. Sie lösen sich in Wasser in ihre Bestandteile auf und sind außerdem besonders leicht brennbar und verkohlbar.Papers of any desired weight from 30 to 150 g / m 2 are obtained and can be written on in a known manner. They dissolve into their components in water and are also particularly easily combustible and charring.
Wird ein solches Papier entzündet, schon die Berührung mit einer glühenden Zigarette ist hierfür ausreichend, so wird das Material durch Verglimmen und Verkohlen vollkommen zerstört. Je schwerer im Gewicht ein Papier ist bzw. mehr einzelne Lagen aufeinanderliegen (Aktenbündel), um so schneller und intensiver geht die Verbrennung vor sich. Es bleiben nur die nicht brennbaren Füllstoffe in Form von glühender Asche zurück. Jegliche Beschriftung ist selbstverständlich verschwunden, und es ist unmöglich, auch nur das geringsteIf such a paper is lit, just touching a glowing cigarette is sufficient for this, so the material is completely destroyed by smoldering and charring. The heavier im If the weight is one piece of paper or if there are more individual layers on top of one another (bundle of files), the faster and the burning is more intense. Only the non-flammable fillers remain back in the form of glowing ashes. Any lettering has of course disappeared, and it is impossible even the slightest

Ein Wirrfaservlies aus 100·% Zellwollfasern mit einem Gewicht von 20 g/m2 wird mit einer Mischung getränkt, die besteht aus:A random fiber fleece made of 100% cellulose fibers with a weight of 20 g / m 2 is impregnated with a mixture consisting of:
1,5 Teilen Netzmittel.1.5 parts wetting agent.
Das nach dem Tränken und Trocknen erhaltene Halbmaterial im Gewicht von etwa 45 g/m2 wird nach dem Befeuchten auf etwa 5fl/o Feuchtigkeitsgehalt auf einem geheizten Kalander bei etwa 110° C geglättet. The semi-finished material obtained after impregnation and drying, weighing about 45 g / m 2 , is smoothed after being moistened to a moisture content of about 5 fl / o on a heated calender at about 110 ° C.
Man erhält ein Schreibpapier (Durchschlagpapier), das sowohl nach Anzünden sehr rasch verbrennt bzw. verkohlt als auch in Wasser in seine Bestandteile zerfällt. The result is writing paper (carbon copy paper) which both burns very quickly after lighting or charred and disintegrates into its constituent parts in water.
