Description

Verfahren zum Herstellen von selbsterstarrenden Kernbindemitteln Bei der Herstellung von Gießereikernen aus Sand kommen bekanntlich die verschiedenartigsten Bindemittel zur Anwendung. So kann man z. B. Klebstoffe in: wäßriger Lösung mit. dem Sand mehgen und,daraus Kerne formen, die entweder an der Luft trocknen öder in Trockenöfen getrocknet werden.Process for the manufacture of self-solidifying core binders Bei It is well known that the manufacture of foundry cores from sand involves the most diverse Binders for use. So you can z. B. Adhesives in: aqueous solution with. meh the sand and form cores out of it, which either dry or dry in the air be dried in drying ovens.

Es ist auch bereits ein Verfahren zum Herstellen von selbsterstarrenden Kernbindemitteln bekannt, und es, ist auch. nicht mehr neu, Öl und Dextrin zu einer kolloidalen Mischung zu vereinen. Dieser Mischung werden noch Wasser und als Stabilisator Fischleim; zugesetzt. Ein unerwarteter Erfolg wird aber für ein Kernbindemittel dadurch nicht erzielt, da nur der Grad der Mischung verbessert wird, nicht aber eine grundsätzliche Verbesserung der Kernbeschaffenheit oder der Kernherstellung erfolgt. Die Erfindung, betrifft eberdalls. ein Verfahren zum Herstellen, von selbsterstarrenden Kernbindemitteln und zeichnet sich dadurch, aus, daß Leimgallerte und mit Trockenstoffen! versetztes, trocknenäes, oder halbtrocknendes Öl zu einer haltbaren Emulsion von salben- oder pastenartiger Beschaffenheit vereinigt werden.It is also already a method of making self-solidifying Core binders are known, and it is, too. no longer new, oil and dextrin into one unite colloidal mixture. This mixture will add water and act as a stabilizer Isinglass; added. However, it becomes an unexpected success for a core binder not achieved as a result, as only the degree of mixing is improved, but not a fundamental improvement in the quality of the core or in the manufacture of the core he follows. The invention relates to everywhere. a method of making, self-solidifying Core binders and is characterized by the fact that glue gel and with drying agents! mixed, drying or semi-drying oil to a durable emulsion of ointment-like or paste-like consistency are combined.

Al(s. Fortschritt des nach dem Verfahren gemäß der Erfindung hergestellten gegenüber den bisher zu den gleichen oder ähnr lichen Zwecken verwendeten Mitteln sei erwähnt, daß die Mischung mit dem Kernsand zur Herstellung der Gießereikerne ohne eine Anwärmung der Emulsion und auch. ohne eine Erwärmung des Sandes .selbst durchgeführt werden; kann. Die Emulsion ist unbegrenzt und ohne Entmischung halbbar. Sie, kann sogar in feuchten und warmen Räumen aufbewahrt werden, ohne daß Fäulniserscheinungen auftreten. Es können mit diesem Kernbindemittel Kerne beliebiger Gestalt hergestellt werden, ohne daß eine Deformierung oder ein Zerfallen der Kerne zu befürchten ist- Besonders vorteilhaft isst es, daß die Kerne, die in Kernkästen geformt werden, selbst erstarren und erst nach der Erstarrung im Ofen getrocknet werden.Al (see progress of the manufactured by the method according to the invention compared to the means previously used for the same or similar purposes it should be mentioned that the mixture with the core sand for the production of the foundry cores without heating the emulsion and also. without heating the sand itself be performed; can. The emulsion is unlimited and can be halved without segregation. It can even be stored in damp and warm rooms without any signs of rot appear. Cores of any shape can be produced with this core binder, without fear of deformation or disintegration of the kernels - especially It is advantageous that the kernels, which are formed in core boxes, solidify themselves and only dried in the oven after solidification.
