Description

Verfahren zum Herstellen eines gummielastischen Gegenstandes aus thermoplastischem Kunststoff Gegellstalld der Erfindung ist ein Verfahren zur f-Ierstellung eines gummielastischen Gegenstandes aus einem Thermoplasten. der durch Bestrahlung mit energiereichen Wellen- oder Korpuskularstrahlen in den elastischen Zustand übergeführt wird. Das Verfahren gemäß der Erfindung besteht darin, daß die Bestrahlung erst nach der Formgebung des Kunststoffes zu einem Gewehe, Gespinst oder Geflecht. geg( helltllfalls in inerter Gasatmosphäre oder unter V aktlum. vorgenommen wird. ills Strahlung kommen Röntgenstrahlen, Gamma-.9irahlen. Elektrotlenstrahlen oder andere Korpuslcularstrahlen entsprechend hoher Energie in Frage. Es eignen sich inshesondere solche Thermoplaste. deren Ketten- und Verzweigungsglieder aus Kohlenstoff und \NTasberstoff bestehen, wie Polyäthylen, STaturkautschuk. synthetischer Kautschuk oder Poly-p-xyllylen. Method for producing a rubber-elastic object from thermoplastic plastic Gegellstalld of the invention is a method for production a rubber-elastic object made of a thermoplastic. that by irradiation converted into the elastic state with high-energy wave or corpuscular rays will. The method according to the invention is that the irradiation only after the plastic has been shaped into a thread, web or braid. given ( brightly in an inert gas atmosphere or under vacuum. is made. ills Radiation comes x-rays, gamma rays. Electrode rays or others Corpuscular rays corresponding to high energy are in question. They are particularly suitable such thermoplastics. their chain and branching links made of carbon and nasal matter consist of polyethylene, natural rubber. synthetic rubber or poly-p-xyllylene.

Darül)er hinaus können auch solche Thermoplaste verwendet werden. deren Ketten- und Verzweigungsglieder außer Kohlenstoff und Wasserstoff noch aiidere Atome, z. B. Stickstoff, Sauerstoff, Schwefel oder f lalogene enthalten, wie Polyvinylalkohol oder Polyacrylnitril.Such thermoplastics can also be used. their chain and branching links have other than carbon and hydrogen Atoms, e.g. B. nitrogen, oxygen, sulfur or halogen, such as polyvinyl alcohol or polyacrylonitrile.

Die Erfindung macht Geh rauch von der bekannten Ersclleinung, daß gewisse Kunststoffe. wie Polyäthylein. unter der Einwirkung von energiereicher Strahlung in einen flexibleren Zustand übergeführt werden liömlen. Dies beruht darauf, daß unter dem Einfluß der Strahlung eine Vernetzung des Thermoplasten eintritt. und zwar durch Abspaltung von Wasserstoff oder entsprechender Substituenten der SIakromolerille, die Querverhindungen zwischen den linearen Ketten bilden. Wichtig ist. daß die Strahlung so dosiert wird, daß nur eine geringe Vernetzung des Thermoplasten bewirkt wird; beim Überschreiten eines gewissen Vernetzungsgrades, der in der Größenordnung von einigen Prozenten liegt, geht der Effekt verloren. Unter Bestrahlungsdosis wird hier die absortierte Energie pro Gramm bestrahlter Substanz verstanden. The invention makes smoke from the known Ersclleinung that certain plastics. like polyethylene. under the action of high-energy radiation be transferred to a more flexible state. This is because Crosslinking of the thermoplastic occurs under the influence of radiation. and although by splitting off hydrogen or corresponding substituents of the SIakromolerille, form the links between the linear chains. Important is. that radiation is dosed in such a way that only a slight crosslinking of the thermoplastic is effected; when a certain degree of crosslinking is exceeded, which is in the order of magnitude of a few percent, the effect is lost. Taking radiation dose is understood here as the absorbed energy per gram of irradiated substance.

Der besondere Wert des erfindungsgemäßen Verfahrens ist darin zu sehen, daß es die Herstellung gummielastischer Gegenstände wie Gewebe, Gespinste oder Geflechte aus Thermoplasten ermöglicht, die sell)st nicht oder nur wenig gummielastisch sind, und zwar dadurch, daß die Elastizität erst nach der Formgehrung also nach dem Verweben, Verspinnen oder Verflechten durch Bestrahlung mit energiereichen Wellen- oder Korpuskularstrahlen herbeigeführt wird. The particular value of the method according to the invention is to be found therein see that there is the production of rubber-elastic objects such as fabrics, webs or braids made of thermoplastics, which sell) st not or only slightly rubber-elastic are, namely, that the elasticity only after the miter shape so after weaving, spinning or interweaving by irradiation with high-energy waves or corpuscular rays is brought about.

Dies ist nämlich für die technische Herstellung von großer Bedeutung, da sich elastische Ausgangsstoffe schlechter verweben, verspinnen oder verflechten lassen als unelastische Stoffe. Die Erfindung bringt daher große technische Vorteile für die Herstellung von gummielastischen Bändern, Seilen oder gummielastischen Geweben, Gespinsten oder Geflechten aus Thermoplasten. Besondere Bedeutung hat die Erfindung für die Herstellung von Isoliermänteln, Isoliergespinsten oder -geweben aus Thermoplasten für elektrische Leiter oder anderer elektrischer Einrichtungen.This is namely of great importance for the technical production, because elastic raw materials weave, spin or intertwine more poorly leave as inelastic fabrics. The invention therefore brings great technical advantages for the production of elastic bands, ropes or elastic fabrics, Spun or braids made from thermoplastics. The invention is of particular importance for the production of insulating jackets, insulating webs or fabrics made of thermoplastics for electrical conductors or other electrical equipment.

Die durch die erfindungsgemäße Behandlung erreichbaren Änderungen der Flexibilität der genannten Thermoplaste sind an folgendem Beispiel zu ersehen Eine 5 mm breite und 0,04 mm dicke Polyäthylenfolie wies nach einer Behandlung mit 60-kV-Elektronen bei einer absorbierten Energie von etwa 1800 Joule/g eine elastische Dehnbarkeit um rund 100r)/e auf. Bei gleicher Zugbelastung der unbestrahlten Folie beginnt diese zu fließen und erfährt eine völlig unelastische Verformung. The changes that can be achieved by the treatment according to the invention the flexibility of the thermoplastics mentioned can be seen in the following example A 5 mm wide and 0.04 mm thick polyethylene film showed after treatment 60 kV electrons with an absorbed energy of around 1800 joules / g are elastic Extensibility by around 100r) / e. With the same tensile load on the unirradiated film this begins to flow and experiences a completely inelastic deformation.

Zur Vermeidung von gelegentlich störender Sauerstoffeinwirkung ist es in gewissen Fällen zweckmäßig, die Bestrahlung in inerter Atmosphäre, z. B. in Stickstoff, oder auch im Vakuum durchzuführen. To avoid the occasional disruptive effect of oxygen it is useful in certain cases, the irradiation in an inert atmosphere, z. Am Nitrogen, or in a vacuum.
