Description

Verfahren zur Herstellung von Formkörpern Die Erfindung betrifft ein Verfahren zur Herstellung von Formkörpern, insbesondere von Hohlkörpern für Verpackungszwecke aus anorganischen Stoffen.Process for the production of moldings The invention relates to a Process for the production of shaped bodies, in particular hollow bodies for packaging purposes from inorganic substances.

Es ist vom Erfinder bereits vorgeschlagen worden, bei der Herstellung von Hohlkörpern von solchen pulverigen anorganischen Stoffen auszugehen (wie z. B. Alkalisilicate, Erdalkalisilicate u. dgl.), die unter Einwirkung von Druck und einer mäßigen Erwärmung ihr Kristallwasser freigeben und dadurch plastisch werden und (infolgedessen im gleichen Arbeitsgange durch spanlose Behandlung, wie Walzen, Stanzen, Pressen o. dgl., geformt werden können. Solche in einem Arbeitsgange hergestellten Formkörper aus anorganischen Ausgangsstoffen weisen ausnahmslos unansehnliche Oberflächen, auf, die in einem weiteren Arbeitsgange durch Lacküberzüge verdeckt werden mußten. Die Erfindung bezweckt, diese zusätzliche Oberflächenbehandlung unnötig zu machen. Es hat sich überraschenderweise herausgestellt, daß das einstufige Herstellungsverfahren mit einer Verlackungsbehandlung vereinigt werden kann, wenn solche basischen oder sauren Teerfarbstoffe in Pulverform dem pulverigen Ausgangsstoff zugemischt werden, die mit den letzteren Adsorptionsfarblacke bilden können oder für die die anorganischen Ausgangsstoffe das Substrat zur Bildung von Fällungsfarblacken abgeben können. Unter Einwirkung von Druck und Wärme bilden diese basischen oder sauren Teerfarbstoffe in unlöslichen Verbindungen Adsorptionsfarblacke oder Fällungsfarblacke, die jede weitere Lack- oder Farbbehandlung des aus der sparlosen Formung hervorgehenden Ergebnisses unnötig machen. Wenn als wesentlicher Bestandteil der anorganischen Ausgangsstoffe pulverisiertes Wasserglas mit einem entsprechenden Gehalt von Na20 verwendet wird, so hat sich überraschenderweise gezeigt, daß durch-.eine verhältnismäßig geringfügige Erhöhung der zugesetzten basischen oder sauren Teerfarbstoffe eine Einkapselung des an sieh wasserlöslichen Alkalis (\Ta20) eintritt und also das fertige Formstück dadurch wasserunlöslich wird.It has already been proposed by the inventor during manufacture to assume hollow bodies of such powdery inorganic substances (e.g. B. Alkali silicates, alkaline earth silicates and the like.), Which under the action of pressure and a moderate warming release their crystal water and thereby become plastic and (as a result, in the same operation by non-cutting treatment, such as rolling, Stamping, pressing or the like. Can be shaped. Such produced in one operation Moldings made from inorganic raw materials invariably have unsightly surfaces, on, which had to be covered by varnish coatings in a further operation. The invention aims to make this additional surface treatment unnecessary. It has surprisingly been found that the one-step manufacturing process can be combined with a laking treatment if such basic or acid tar pigments in powder form are added to the powdery starting material, which can form adsorptive lakes with the latter, or for the inorganic ones Starting materials can give off the substrate for the formation of precipitation colored lacquers. Under The effects of pressure and heat form these basic or acidic tar pigments in insoluble compounds adsorption color lakes or precipitation color lakes, which each further lacquer or color treatment of the result resulting from the economical shaping make unnecessary. If as an essential part of the inorganic starting materials powdered Water glass with a corresponding content of Na20 is used, so has Surprisingly shown that by-.a relatively slight increase the added basic or acidic tar dyes encapsulate the to see water-soluble alkali (\ Ta20) occurs and thus the finished fitting becomes insoluble in water.
