Description
Verfahren zur Herstellung von harzartigen Kondensationsprodukten Gegenstand des Hauptpatents 536 553 ist ein Verfahren zur Herstellung von harzartigen Kondensationsprodukten, bei welchem man die von einem einwertigen Phenol und Resorcin bei Gegenwart von Aldehyd getrennt gebildeten und dann vereinigten Halbkondensate mit einem Füllstoff verbindet.Process for the production of resinous condensation products Subject of the main patent 536 553 is a process for the production of resinous condensation products, in which one gets that of a monohydric phenol and resorcinol in the presence of Aldehyde formed separately and then combined semi-condensates with a filler connects.
Das Verfahren kann dadurch vereinfacht bzw. ergänzt werden, daB man die Kondensation von Resorcin mit Formaldehyd oder dessen Homologen zum gegebenen Zeitpunkt in einer Lösung oder einer Schmelze eines Vorkondensates eines einwertigen Phenols mit Formaldehyd vornimmt, wobei die bei der Kondensation von Resorcin und Aldehyd entwickelte Wärme vorteilhaft für die Weiterkondensation des langsam reagierenden Monophenolaldehydharzes ausgenutzt wird, weiterhin die Ausbackzeiten beider Harze einander angeglichen werden und so eine beschleunigte Homogenisierung des Harzgemisches und eine Abkürzung des Verfahrens erzielt werden.The procedure can be simplified or supplemented by the fact that one the condensation of resorcinol with formaldehyde or its homologues for the given Point in time in a solution or a melt of a precondensate of a monovalent one Phenol takes on formaldehyde, with the condensation of resorcinol and Aldehyde developed heat beneficial for the further condensation of the slowly reacting Monophenol aldehyde resin is exploited, the baking times of both resins continue are adjusted to each other and thus an accelerated homogenization of the resin mixture and an abbreviation of the process can be achieved.
Beispiel i In 17,5o kg einer 5o°/aigen alkoholischen Lösung von Monophenolaldehydkondensat, beispielsweise Kresolformaldehyd, werden unter gelindem Erwärmen 5,65 kg Resorcin bis zur völligen Lösung eingerührt. Alsdann wird die Temperatur auf etwa 70'-gesteigert, und es werden 3,ZO kg Paraformaldehyd hinzugesetzt. Das Erhitzen wird unter dauerndem Rühren der Mischung so lange fortgesetzt, bis auch der Aldehyd in Lösung gegangen ist, worauf die Flüssigkeit ins Sieden gerät. Man kühlt schnell ab, setzt 32,5o kg Holzmehl zu und mischt das Ganze 1/2 Stunde gut durch. Die Masse wird an der Luft oder im Vakuum bis zur Entfernung von Alkohol und Wasser getrocknet und ist dann preBfertig.Example i In 17.5o kg of a 50% alcoholic solution of monophenol aldehyde condensate, for example cresol formaldehyde, 5.65 kg of resorcinol are obtained with gentle heating Stirred in until completely dissolved. Then the temperature is increased to about 70 ', and 3. ZO kg of paraformaldehyde are added. The heating will be under constant Stirring the mixture continued until the aldehyde also went into solution is whereupon the liquid boils. You cool down quickly, bet 32.5o kg of wood flour and mix well for 1/2 hour. The crowd is at the Air or in a vacuum until the alcohol and water are removed and is then ready for use.
Beispiel 2 32,5o kg Holzmehl, io,5o kg Kresolformaldehydkondensat in 5o°/oiger alkoholischer Lösung, 7,95 kg Resorcin, 4,30 kg Paraformaldehyd werden im Mastikator 1/2 Stunde lang gut durchgemischt. Die feuchte Masse wird an der Luft oder im Vakuum bis zur restlosen Entfernung von Alkohol und Wasser getrocknet und dann zwischen Walzen von go ° bis ioo °- fein ausgewalzt. Das Ganze verschmilzt hierbei zu einer teigigen, homogenen Masse, die nach dem Abkühlen wieder erhärtet. Die Platten werden vorgebrochen und dann 5 Stunden in der Kugelmühle fein gemahlen. Die Masse ist dann preB-fertig.Example 2 32.5o kg of wood flour, 10.5o kg of cresol formaldehyde condensate in 50% alcoholic solution, 7.95 kg of resorcinol and 4.30 kg of paraformaldehyde are added Mix well in the masticator for 1/2 hour. The moist mass is exposed to the air or dried and in a vacuum until the alcohol and water have been completely removed then between rollers from go ° to ioo ° - finely rolled out. The whole merges this results in a doughy, homogeneous mass that hardens again after cooling. The plates are pre-crushed and then finely ground in a ball mill for 5 hours. The mass is then ready for preB.
