Description
Verfahren zum Leimen von Papier mit tierischem Leim oder Eiweißstoffen. Zusatz zum Patent 331350. Durch Patent 331350 ist ein Verfahren zum Leimen von Papier mit tierischem Leim oder Eiweißstoffen geschützt, das dadurch gekennzeichnet ist, daß das Unlöslichmachen dieser Stoffe durch Sulfosäuren ungesättigter Kohlenwasserstoffe (besonders der höheren Kohlenwasserstoffe des Steinkohlenteers) und durch die aus diesen durch Erhitzen zu erhaltenden Kondensationsprodukte, oder durch die aus diesen Sulfosäuren mit Formaldehyd zu erhaltenden Kondensationsprodukte, oder durch die aus diesen Sulfosäuren mit Phenolsulfosäuren zu erhaltenden Kondensationsprudukte bewirkt wird.Process for gluing paper with animal glue or protein substances. Addendum to patent 331350. By patent 331350 is a method for sizing paper protected with animal glue or protein, which is characterized by that the insolubility of these substances by sulfonic acids of unsaturated hydrocarbons (especially the higher hydrocarbons of coal tar) and by the these condensation products to be obtained by heating, or by those from these Sulphonic acids with formaldehyde to be obtained condensation products, or by the condensation products to be obtained from these sulfonic acids with phenol sulfonic acids is effected.
Es wurde nun gefunden, daß man an Stelle der vorgenannten Stoffe auch andere organische, künstlich hergestellte; leimfällende Substanzen, wie z. B. die Produkte, deren Darstellung und Verwendung zum Gerben in den deutschen Patentschriften 262558, 280233, 29o965 und 292531 beschrieben ist, für diesen Zweck mit Vorteil verwenden kann. Man arbeitet hierbei zweckmäßig bei gleichzeitiger Anwesenheit von Harzleim oder Harzseife. Statt dieser öder zugleich mit ihnen können auch Emulsionen von Harzen, z.B. auchdienachderdeutschenPatentschrift 307123 aus künstlichen Harzen erzeugten Emulsionen verwendet werden. Beispiel. Man bringt zu der Papiermasse im Hclländer, bezogen auf' trockene Masse, Lösungen von o,25 Prozent Harzleim, 2 Prozent Tierleim, q. Prozent des im Handel unter dem Namen »Neradol D« erhältlichen, nach der deutschen Patentschrift 262558 hergestellten Kondensationsproduktes aus Kresolsulfesäure und Formaldehyd sowie i bis 2 Prozent schwefelsaure Tonerde und macht das Papier in üblicher Weise fertig.It has now been found that other organic, artificially produced substances can also be used in place of the aforementioned substances; glue-precipitating substances, such as. B. the products whose presentation and use for tanning is described in German patents 262558, 280233, 29o965 and 292531 can be used with advantage for this purpose. It is expedient to work here with the simultaneous presence of resin glue or resin soap. Instead of these or at the same time as them, emulsions of resins, for example also emulsions produced from synthetic resins according to German patent specification 307123, can also be used. Example. One brings solutions of 0.25 percent resin glue, 2 percent animal glue, q. Percent of the condensation product of cresolsulfesic acid and formaldehyde, which is commercially available under the name "Neradol D" and manufactured according to German patent specification 262558, and 1 to 2 percent of sulfuric alumina and makes the paper ready in the usual way.
In ähnlicher Weise verfährt man bei Verwendung der nach der deutschen Patentschrift 305795 hergestellten Kondensationsprodukte oder anderer organischer, leimfällender Substanzen.A similar procedure is followed when using the condensation products prepared according to German patent specification 305795 or other organic, glue-precipitating substances.
