Description

Verfahren zur Herstellung eines Bindemittels. Zusatz zum Patent 393546*). Die Erfindung bezweckt die weitere Ausbildung des durch das Patent 393546 und das Zusatzpatent 405182 geschützten Verfahrens zur Herstellung einer insbesondere als Brikettbindemittel geeigneten Masse aus Säureharzen oder Rückständen, die hauptsächlich aus Säureharzen bestehen.Process for the production of a binder. Addition to patent 393546 *). The invention aims at the further development of the patent 393546 and the Additional patent 405182 protected process for the production of a particular as Briquette binder suitable mass of acid resins or residues, which are mainly consist of acid resins.

Nach dem Hauptpatent werden die Säureharze einer gleichzeitigen Behandlung mit alkalischen Mitteln und Luft unterworfen, und zwar wird das Harz beispielsweise mit gemahlenem Ätzkalk zusammengeschmolzen und dann mehrere Stunden in der Hitze mit Luft behandelt.According to the main patent, the acid resins are subject to simultaneous treatment subjected to alkaline agents and air, namely the resin is for example melted together with ground quicklime and then in the heat for several hours treated with air.

Es hat sich nun gezeigt, daß es vorteilhaft ist, dieser Behandlung mit Alkali und Luft eine Entsäuerung des Harzes mit Alkali vorangehen und hierbei die für die weitere Behandlung notwendige Menge Alkali in dem Harz zurückzulassen. Ein Überschuß von Alkali kann mit Wasser ausgewaschen werden.It has now been shown that this treatment is beneficial with alkali and air a deacidification of the resin with alkali precede and this leaving the necessary amount of alkali in the resin for further treatment. An excess of alkali can be washed out with water.

Ausführungsbeispiel. 1000 kg Säureharze werden mit Kalkmilch, bereitet .aus 2o bis ioo kg Ätzkalk, bei ge,-linder Wärme durchgeknetet, bis die Masse von vorher vorhandener freier Schwefelsäure befreit ist und alkalische Reaktion angenommen hat. Hierauf wird das entsäuerte Harz von dem wäßrigen Anteil getrennt und gemäß den Patenten 393546 und 405182 weiterbehandelt.Embodiment. 1000 kg of acid resins are kneaded with milk of lime, prepared from 2o to 100 kg of quick lime, at moderate heat, until the mass has been freed from the free sulfuric acid that was previously present and has assumed an alkaline reaction. The deacidified resin is then separated from the aqueous portion and further treated in accordance with patents 393546 and 405182.
