Description
Verfahren zur Herstellung von geschichteten Isolierstoffen, insbesondere mikanitähnlichen Stoffen unter Verwendung eines lösungsmittelfrefen Klebemittels Zur Herstellung von Mikanit und ähnlichen geschichteten Isolierstoffen wird Schellack im gelösten oder geschmolzenen Zustand verwendet. Nun steht aber Schellack als Auslandsprodukt nicht mehr in ausreichender Menge zur Verfügung. Die Erfindung hat die Aufgabe, diesen seltenen Sparstoff bei der Herstellung von geschichtetem Isoliermaterial, insbesondere mikanitähnlichemIsolierstoff, entbehrlich zu machen. Erfindungsgemäß werden zwischen die zu verklebenden Schichten Hartwachs, Hartpech in Staubform oder ähnliche schmelzbar bzw. versinterbare Stoffe eingebracht, und das Isoliermaterial wird unter Anwendung von Hitze und Druck verformt. Auf diese Weise kann man Glimmerblättchen, Glasfilm oder ein Gemisch aus beiden zu mikanitartigen Gebilden verarbeiten. Als besonders brauchbar haben sich Montanwachs und Steinkohlen- sowie Braunkohlenteerpech erwiesen. Beide Stoffe sind billig und leicht zu beschaffende Inlandsstoffe. Der Staub dieser Stoffe braucht lediglich zwischen die zu verklebenden Lagen von Glimmer-und Glasfilm gebracht und unter Hitze und Druck zusammengeschmolzen zu werden. Das auf diese Weise hergestellte Isoliermaterial kann in derselben Art weiterverarbeitet werden wie Schellack-Mikanit.Process for the production of layered insulating materials, in particular micanite-like substances using a solvent-free adhesive Shellac is used to manufacture micanite and similar layered insulating materials used in the dissolved or molten state. Shellac is now available as a foreign product no longer available in sufficient quantities. The invention has the task this rare resource in the production of layered insulation material, In particular, micanite-like insulating material can be dispensed with. According to the invention between the layers to be bonded hard wax, hard pitch in the form of dust or similar meltable or sinterable substances introduced, and the insulating material is deformed with the application of heat and pressure. In this way you can get mica flakes, Process glass film or a mixture of both to form mica-like structures. as Montan wax and coal and lignite tar pitch are particularly useful proven. Both fabrics are cheap and easy to source domestic fabrics. Of the Dust from these substances only needs to be placed between the layers of mica and to be bonded Glass film brought and melted together under heat and pressure. That on Insulation material produced in this way can be further processed in the same way become like shellac micanite.
Die Erfindung bietet den Vorteil, daß an Stelle des schwer zu beschaffenden ausländischen Stoffes billige Inlandsstoffe treten können. Die angegebenen Stoffe haben noch den besonderen Vorteil, daß sie beim Schmelzen kein Wasser abspalten, keine unerwünschte Härtung mitmachen und daß ihr Viskositätsverlauf leicht durch Weichmacherzusatz einstellbar ist. Ferner kann der Schmelzpunkt dieser Stoffe durch geeignete chemische Behandlung weit über den des Schellacks erhöht werden.The invention offers the advantage that instead of the difficult to obtain foreign fabric can enter cheap domestic fabrics. The specified substances have the special advantage that they do not split off water when melting, do not participate in undesired hardening and that their viscosity curve easy can be adjusted by adding plasticizers. Furthermore, the melting point of these substances can be increased far above that of shellac by suitable chemical treatment.
