Description
Masse für Formschalen für Metall- oder Eisenguß Bei der Herstellung der Formschalen für Metall- oder Eisenguß spielt neben@ dem Grundstoff das Bindemittel eine wesentliche- Rolle,. Es muß der Form die genügende Festigkeit geben, damit sie dem beim Gießen auftretenden Druck standhält; es darf aber weder hei der Herstellung der Form noch während des Gießens die Ma,ßhaltigkeit des Gußstückes oder dessen Oberfläche" sei es mecha nisch, sei es chemisch, beeinflussen. Die: Erfindung betrifft die Formmasse für derartige Formschalen und besteht darin, daß unter Verwendung einer Icärnigen. Komponente (Mineralpulver, Metallspäne ad. dgl.) als Bindemittel Salze aus hochmolekularen mehrbasischen Säuren (Podyakrylsäure" Polymethakrylsäure! usw.) und Di- oder Polyaminen, dienen. Die verwendeten Amine sind insbesondere Äthylendiamine oder Hexamethylendiamine, die, für sich allein oder in Mischung verwendet sind. In einer Weiterbildung der Erfindung ist es zweckmäßig, als Ausgangsstoff voni Mischpolymerisaten auszugehen, diel z. B. aus Vinylverbindungen. mit ungesättigten Di- oder Polycarbonsäuren (llaleinsäure, Fumarsä,ure od. dgl.) bestehen.Compound for molded shells for metal or iron casting during manufacture In addition to the base material, the binding agent plays the role of the shell molds for metal or iron casting an essential role. It has to give the form the strength it needs it can withstand the pressure generated during casting; but it must not be used during manufacture the shape even during casting, the dimensional accuracy of the casting or its Surface "be it mechanically or chemically. The: Invention relates to the molding compound for such molded shells and consists in that using an Icarnian. Component (mineral powder, metal shavings, etc.) as a binder Salts from high molecular weight polybasic acids (podyacrylic acid "polymethacrylic acid! etc.) and diamines or polyamines. The amines used are in particular ethylene diamines or hexamethylenediamines, used alone or in admixture. In a further development of the invention, it is expedient to use copolymers as the starting material to go out, the z. B. from vinyl compounds. with unsaturated di- or polycarboxylic acids (llaleic acid, fumaric acid, ure or the like.) exist.
