Abstract

A method of manufacturing shoe insoles or the like is described. The soles consist of silicone rubber which is hardened by microwave radiation. As heat activator, a substance which contains water in bound form is added to the sole material. Examples are flour or plaster.

Description

"Verfahren zum Herstellen von Formteilen in genauer Paßform, insbesondere von Schuheinlege-Sohlen" (nach Patent ..... Patentarmeldung P 34 05 964.4) Die Erfindung betrifft ein Verfahren der im Oberbegriff des Anspruches 1 genannten Art nach Patent (Patentanmeldung P 34 05 364.4)."Process for producing molded parts in an exact fit, in particular of shoe insoles "(according to patent ..... patent arm report P 34 05 964.4) The invention relates to a method of the type mentioned in the preamble of claim 1 according to the patent (Patent application P 34 05 364.4).

Das i@ Stammpatent beschriebene Verfahren betrifft die Herstellung vor Schuheinlege-Sohlen in genauer Paßform aus einem heiß aushärtenden Silikon-Kautschuk. Bei diesem verfahren wird dem Silikon- Kautschuk blättriger Graphit beigemischt , urr die zur Aushärtung des V.erkstoffes e-ford-ri^ne Erhitzung einfach und schnell durch Mikrowellenbestrahlung vornehmen zu kennen. Der Flocken-Gr-phit hat dabei die Funktion eines Erhitzungs-A@tivators, ohne den die Mikrowellenbestrahlung @icht zur Erhitzung fuhren würde.The process described by i @ parent patent concerns the production in front of shoe insoles in a precise fit made of a hot-curing silicone rubber. In this process, flaky graphite is mixed with the silicone rubber , urr the quick and easy way to harden the material e-ford-ri ^ ne heating make to know by microwave irradiation. The flake gr-phit has it the function of a heating activator, without which the microwave irradiation @light would lead to heating.

Die Erfindung betrifft einen anderen Zusatzstoff als Wärmeaktivator bei den Mikrowellenbestrahlung. Sie geht von der Erkenntnis aus, daß die Erhitzung eines Gegenstandes durch Mikrowellenbestrahlung das Vorhandensein von wasser in dem bestrahlten Gegenstand voraussetzt oder jedenfalls von Vorteil sein läßt.The invention relates to an additive other than a heat activator in the case of microwave irradiation. It is based on the knowledge that the heating an object by microwave irradiation the presence of water in presupposes the irradiated object or at least allows it to be advantageous.

Wasser kann nicht ohne weiteres in Silikon-Kautschuk e ing earte i - e t werd er'. , weil es bei einer Mikrowellenbestranlung -ur Schaumbilaung führen würde. Daher wird erfindungsgemäß allgemein im vorgenannten Sinne als Erhitzungsaktivator ein solcher Stoff verwendet, der Wasser in gebundener Form enthält. Ein solcher Zusatzstoff ist vorteilhaft hygroskopisch.Water cannot easily be e ing earte i in silicone rubber - e t will '. , because with a microwave irrigation-only foam build-up would. Hence will according to the invention in general in the aforementioned sense such a substance is used as a heating activator, the water in bound form contains. Such an additive is advantageously hygroscopic.

Gemäß der Erfindung enthält der Silikon-Kautschuk 1 bis 1O, vorzugsweise 3 bis 5 Gew% dieses Zusatzstoffes.According to the invention, the silicone rubber contains 1 to 10, preferably 3 to 5% by weight of this additive.

Versuche haben ergeben, daß mit höherem Anteil dieses Zusatzstoffes die für das Aushärten des Silikon-Kautschuks durch Mikrowellenbestrahlung erforderliche Bestrahlungszeit verringert wird.Tests have shown that with a higher proportion of this additive that required for the curing of the silicone rubber by microwave irradiation Irradiation time is reduced.

Als im Sinne der Erfindung geeigneter Zusatzstoff hat sich Getreidemehl erwiesen. Dieser Zusatzstoff, der sich einfach mit Silikon-Kautschuk vermischen läßt, verfügt uber eine gewisse Grundfeuchtigkeit - sei dies absorbierte Luftfeuchtigkeit oder dem Mehl von Hause aus inne@ohnende Feuchtigkeit. Mit Mehl als Zusatzstoff im Sinne der Erfindung durchgeführte Versuche haben zu der Erkenntnis geführt, daß mit zunehmender Mehlbeimischung die für die Aushärtung des Silikon-Kautschuks erforderliche Bestrahlungszeit verr@ngert wird. Durch die MikrowellenbestraHlung in einem handelsüblichen Mikrowelle@@erd wird bei Verwendung von Mehl als Zusatzstiff zum Silikon-Kautschuk eine Erwärmung des Silikon-Kautschuks auf seine Aushärtetemperatur von etwa 10C ois 1200 sehr schnell erreicht, so daß eine gesamte Sestrahlurgsdauer von etwa 30 Sekunden ausreichend ist.Grain flour has proven to be a suitable additive for the purposes of the invention proven. This additive that simply mixes with silicone rubber has a certain basic humidity - be it absorbed humidity or the flour inherently lacking moisture. With flour as an additive Tests carried out within the meaning of the invention have led to the finding that with increasing admixture of flour, that required for the hardening of the silicone rubber Irradiation time is reduced. Due to the microwave irradiation in a commercially available Microwave @@ erd becomes silicone rubber when using flour as an additive a heating of the silicone rubber to its hardening temperature of about 10C ois 1200 reached very quickly, so that a total Sestrahlurg duration of about 30 Seconds is sufficient.

Nach dem Aushärten sind der Silikon-Kautschuk bzw. die aus ihm hergestellte Schuheinlege-Sohle formbeständ@g und trotzdem elastisch. wenn die Erfindung anhand an d einer Schuheinlege-Sohle beschrieten ist so ist indessen durchaus denkbar, damit auch a@dere Gegenstande in der erfindungsgemäßen Weise, auch nach oeri. im Hauptpatent beschriebenen Verfahren, herzustellen, beispielsweise solche Waren, wie sie dJrch Modellierton auf dem Spielwaren- und Hobbygebiet ubl@cherweise hergestelit werden.After curing, the silicone rubber or the one made from it are Inlay sole that retains its shape and is still elastic. if the invention based on it is, however, quite conceivable thus also other objects in the invention Way, too after oeri. in the main patent described process to produce, for example such goods as they are usually used in the toy and hobby field by modeling clay be produced.
