  Verfahren zur Herstellung eines leicht brennbaren und wasserlöslichen Papiers auf Faservliesbasis 
Die Erfindung betrifft eine weitere Ausgestaltung des Verfahrens gemäss Stammpatent Nr. 241966. 



  Dort wird ein Verfahren zur Herstellung eines in Wasser innerhalb kürzester Zeit in seine Bestandteile zerfallenden, beschreib-und bedruckbaren Papiers durch Zusetzen von   Füll- und wasserlöslichen   Bindemitteln üblicher Art zum Papiergrundstoff und anschliessendes Trocknen beansprucht. Es ist dadurch gekennzeichnet, dass pro 100 Teile Fasern etwa   40 - 200   Teile Bindemittel und eine ebenso grosse Menge Füllstoffe zugesetzt werden, und nach der Trocknung und nach dem Wieder anfeuchten bis auf einen Feuchtigkeitsgehalt von etwa 3 bis 15% bei einer Temperatur zwischen 50 und   1750C   kalandriert wird. 



   In weiterer Ausgestaltung dieses Verfahrens gemäss Stammpatent setzt man nun dem Papiergrundstoff zusätzlich noch Sauerstoff abgebende Substanzen, wie Nitrate, Chlorate, Perborate und Nitrozellulose zu. 



   Ein derartiges Papier zerfällt nach wie vor bei der Berührung mit Wasser. Es kann zusätzlich aber auch dadurch zerstört werden, dass man es mit einer Flamme in Berührung bringt. Die Sauerstoff abgebende Substanz fördert die Verbrennung in einem solchen Ausmass, dass der Brand auch nicht in einer Sauerstoff-freien Atmosphäre unterdrückt werden kann. 



   Mit Wasser kann die Verbrennung des Papiers zwar unterbunden werden, jedoch zerfällt in diesem Fall das Papier wieder in seine Bestandteile. Ein derartiges Papier ist vor allem für militärische Zwecke sehr geeignet. 



   Zwar ist aus verschiedenen Veröffentlichungen bekannt, einem üblichen Papiergrundstoff Sauerstoff abgebende Substanzen zuzusetzen, um die Brennbarkeit der Papiere zu fördern. Derartige Papiere zerfallen jedoch nicht bei Berührung mit Wasser, so dass sie für militärische Zwecke weniger geeignet sind.

  Process for the production of an easily flammable and water-soluble paper based on fiber fleece
The invention relates to a further embodiment of the method according to parent patent no. 241966.



  There, a process is claimed for producing a writable and printable paper which disintegrates into its constituent parts within a very short time in water by adding fillers and water-soluble binders of the usual type to the paper base material and subsequent drying. It is characterized in that about 40-200 parts of binder and an equally large amount of fillers are added per 100 parts of fibers, and after drying and rewetting to a moisture content of about 3 to 15% at a temperature between 50 and 1750C is calendered.



   In a further embodiment of this process according to the parent patent, oxygen-releasing substances such as nitrates, chlorates, perborates and nitrocellulose are now added to the paper base material.



   Such a paper still disintegrates on contact with water. It can also be destroyed by bringing it into contact with a flame. The oxygen-releasing substance promotes combustion to such an extent that the fire cannot be suppressed even in an oxygen-free atmosphere.



   The burning of the paper can be prevented with water, but in this case the paper disintegrates again into its components. Such a paper is particularly suitable for military purposes.



   It is known from various publications to add oxygen-releasing substances to a conventional paper base material in order to promote the flammability of the papers. However, such papers do not disintegrate on contact with water, so that they are less suitable for military purposes.
