Description

Es sind Schaumstoffe bekannt, die insbesondere aus Kunststoff .bestehen und ein äußerst geringes Raumgewicht aufweisen. Die Verarbeitung und die Formgebung dieser Schaumstoffe bieten jedoch wesentliche Schwierigkeiten.Foams are known which are made, in particular, of plastic and have an extremely low volume weight. The processing and the shaping however, these foams present significant difficulties.

Gemäß der Erfindung wenden diese Nachteile dädurch vermieden, daß der F auf eine Folie, einen Faden od. @dgl., insbesondere aus thermoplastischem Kunststoff, aufgebracht- ist: Hierbei kann der Schaumstoff in beliebiger Form, z. B. in Form von Bändern, Flocken, Spänen; Körnern od. dgl., auf die Trägerfolie od. dgl. aufgebracht, insbesondere aufgeklebt werden. Für elektrische Zwecke ist es besonders vorteilhaft, Schaumpolystyrol auf einer Trägerfolie aus Isolierstoff, insbesondere aus Polystyrol, Polyäthylen, insbesondere in Bandform, aufzukleben. Diese Folien haben an sieh bereits eine relativ niedrige DK, so @daß auch die - gesamte Isolierung eine sehr niedrige DK aufweist.According to the invention, these disadvantages are avoided by the fact that the F on a film, a thread or the like, in particular made of thermoplastic Plastic, is applied: Here, the foam can be in any shape, for. B. in the form of ribbons, flakes, shavings; Grains or the like., Od on the carrier film. Like. Applied, in particular glued on. For electrical purposes it is particularly advantageous, expanded polystyrene on a carrier film made of insulating material, in particular made of polystyrene, polyethylene, especially in tape form, to be glued on. These foils already have a relatively low DK, so that the - entire insulation has a very low DK.

Das Aufklebendes Schaumstoffes erfolgt zweckmäßig mit Klebemitteln, welche .den Schaumstoff und; die Folie nicht angreifen. Für - elektrische Zwecke verwendet man als Klebemittel ,elektrisch hochwertige Auflösungen von geringer DK, "vorzugsweise Polyisöbutylenlösuagen in Benzin oder Petroläther.The adhesive of the foam is expediently carried out with adhesives, which .the foam and; do not attack the foil. For - electrical purposes is used as an adhesive, electrically high-quality resolutions of low DK, "Preferably polyisobutylene solutions in gasoline or petroleum ether.

Die erfindungsgemäße Isolierung kann in verschiedensten Formen ausgeführt und verarbeitet werden. Der Schaumstoff kann: auch in Folien eingewickelt mit diesen versponnen oder verwalz.t werden. Es kann auch eine Schaumstoffolie mit einem Faden aus Polystyrol od. dgl. vereinigt werden.The insulation according to the invention can be implemented in the most varied of forms and processed. The foam can: also be wrapped in foils with these spun or rolled. It can also be a foam sheet with a thread of polystyrene od. The like. Be combined.

Für elektrische Zwecke ist eine derartige Isolierang besonders gut geeignet, da sie eine DK von kleiner als 44 aufweist und somit in vorteilhafter Weise als Isolationsmaterial für Kabel, insbesondere Hoohfrequenzkabel, verwendet werden kann. Das Aufbringen der Isolierung erfolgt hierbei stets so, daß der Schaumstoff dem Leiter zugekehrt ist.Such an insulation is particularly good for electrical purposes suitable because it has a DK of less than 44 and therefore more advantageous Way used as insulation material for cables, especially high frequency cables can be. The insulation is always applied in such a way that the foam facing the leader.

Der Schaumstoff wird bisher in Kuchen.- bzw. Scheibenform geliefert, wovon Bänder abgeschält werden. Dies ist besonders schwierig und mühsam. Gemäß dler weiteren Erfindung wird auf die Mantelfläche der Schaumstoffscheibe eine Folie geklebt und mit dieser ein Band von der Sehaumstoffscheibe abgeschält.So far, the foam has been delivered in cake or slice form, from which tapes are peeled off. This is particularly difficult and troublesome. According to dler Another invention, a film is glued to the outer surface of the foam disc and with this peeled off a tape from the foam disk.

In der Figur ist .dies schematisch veranschaulicht. Die Trägerfolie i, die beispielsweise aus Polystyrdl besteht, wird von. einer Vorratsrolle :2 über die Kleberolle 3 geführt und auf die Schaumstoffscheibe q. aufgeklebt. Von dieser wird sie mittels .des Messers 5 gleichzeitig mit einer Schicht Schaumstoff versehen wieder abgeschält. Die kombinierte Folie 6, bestehend aus Polystyrol und Schaumstoff, wird auf die Rolle 7 aufgewickelt. Es kann somit in einem Arbeitsgang die erfindungsgemäße Isolierung, bestehend aus Schaumstoff und Trägerfolie, hergestellt werden.This is illustrated schematically in the figure. The carrier film i, which consists for example of polystyrene, is of. a supply roll: 2 over the glue roll 3 out and on the foam disc q. glued. Of this it is provided with a layer of foam at the same time by means of the knife 5 peeled off again. The combined film 6, consisting of polystyrene and foam, is wound onto the roll 7. It can thus in one operation the invention Insulation, consisting of foam and carrier film, can be produced.
