Description

Verfahren zur Papierleimung. Ein Verfahren zur Papierleimung ist bereits vorgeschlagen worden, dahingehend, die Leimung durch Fällung von Gelatine mit Kondensationsprodukten aromatischer Kohlenwasserstoffe zu bewirken. Es wurde nun weiter gefunden, daß die Anwendung von Gelatine nicht nötig ist, daß man vielmehr bei Anwendung geeigneter Kondensationsprodukte in der bei der Harzleimung üblichen Weise mit Aluminiumsulfat fällen kann. Anstatt des Aluminiumsulfats kann man auch andere fällende Salze verwenden, z. B. Kalziumchlorid, Magnesiumchlorid.Process for paper sizing. A process for paper sizing is already in place has been proposed to the effect of sizing by precipitation of gelatin with condensation products effect of aromatic hydrocarbons. It has now been further found that the Use of gelatin is not necessary, but rather when using more suitable Condensation products in the usual manner for resin sizing with aluminum sulfate can fall. Instead of aluminum sulphate, other precipitating salts can also be used, z. B. calcium chloride, magnesium chloride.

Für die Leimung im Stoff wird der Papiermasse im Holländer eines der unten näher bezeichneten Kondensationsprodukte in Lösung oder in Suspension abwechselnd mit dem fällenden Salz zugesetzt, je nach dem Leimungsgrad etwa 1/2 bis 5 Prozent des Papiers.For the sizing in the fabric, the paper pulp in the Dutch is one of the Condensation products described in more detail below alternately in solution or in suspension added with the precipitating salt, depending on the degree of sizing about 1/2 to 5 percent of the paper.

Beispiele der verwendbaren Kondensationsprodukte. I. Kondensationsprodukte erhalten durch Behandeln von Mischungen aromatischer Sulfosäuren und aromatischer Kohlenwasserstoffe mit Formaldehyd a) roo Teile Naphthalinsulfosäure (aus 5o Teilen Naphthalin und 5o Teilen Schwefelsäuie durch Sulfieren bei I5o°) mit 75 Teilen Naphthalin, 2o Teilen Wasser gemischt und bei etwa Ioo° unter Rühren 4o Teile Formaldehyd (4o Prozent) eingetragen. Nach beendeter Kondensation wird der Überschuß von Naphthalin mit Wasserdampf abgetrieben.Examples of the condensation products that can be used. I. Condensation Products obtained by treating mixtures of aromatic sulfonic acids and aromatic ones Hydrocarbons with formaldehyde a) 100 parts naphthalene sulfonic acid (from 50 parts Naphthalene and 50 parts sulfuric acid by sulfating at 150 °) with 75 parts naphthalene, Mix 20 parts of water and add 40 parts of formaldehyde (4o Percent). After the condensation has ended, the excess naphthalene is used driven off with steam.

b) Ioo Teile Naphthalinsulfosäure mit 75 Teilen Xylol und 3o Teilen Wasser gemischt und unter Rühren bei Ioo ° 35 Teile Formaldehyd eingetragen. Nach beendeter Kondensation mit Wasser verdünnt und vom 01 getrennt.b) 100 parts of naphthalenesulfonic acid with 75 parts of xylene and 3o parts Mixed water and added 35 parts of formaldehyde with stirring at 100 °. To When the condensation has ended, diluted with water and separated from the 01.

Die Tonerdefällung von b ist weicher und elastischer als die von a.The alumina precipitation of b is softer and more elastic than that of a.

2. Die aus aromatischen Kohlenwasserstoffen mit Formaldehyd bei Gegenwart von Säuren auf verschiedene Weise zu erhaltenden Kondensationsprodukte. Diese Produkte sind in Wasser unlöslich und werden als Suspension verwendet.2. Those made from aromatic hydrocarbons with formaldehyde in the presence Condensation products to be obtained from acids in various ways. These products are insoluble in water and are used as a suspension.

3. Die Kondensationsprodukte aus aromatischen Kohlenwasserstoffen durch Erhitzen mit einer zur Bildung der Sulfosäuren ungenügenden Menge Schwefelsäure. In roo Teile Schwefelsäure werden bei 170' Zoo Teile Naphthalin langsam unter Rühren eingetragen und weiter etwa 8 Stunden erhitzt. Die Masse wird in Wasser gelöst und das überschüssige Naphthalin mit Wasserdampf abgetrieben.3. The condensation products from aromatic hydrocarbons by heating with an insufficient amount of sulfuric acid to form the sulphonic acids. In roo parts of sulfuric acid at 170 'zoo parts of naphthalene are slowly added with stirring entered and further heated for about 8 hours. The mass is dissolved in water and the excess naphthalene is driven off with steam.

q.. Die Sulfone aromatischer Kohlenwasserstoffe, z. B. Dinaphtylsulfon.q .. The sulfones of aromatic hydrocarbons, e.g. B. Dinaphthyl sulfone.

Ganz allgemein sind Produkte verwendbar, die mehr als einen aromatischen Kern im Molekül enthalten, nicht flüchtig sind und entweder in Wasser unlöslich sind oder mit Aluminiumsulfat oder Erdalkalisalzen unlösliche Fällungen geben.In general, products that have more than one aromatic can be used Nuclei contained in the molecule, are non-volatile and either insoluble in water or give insoluble precipitates with aluminum sulfate or alkaline earth salts.
