Description

Schrumpfkörper Es ist gefunden worden, daß man zu neuartigen Schrumpfkörpern, wie beispielsweise Flaschenkapseln, Schläuchen, Ringen, schaChtel- oder dosenartigen Gebilden usw., gelangt, wenn man zur Herstellung dieser Gebilde das nachstehend genannte Ausgangsmaterial verwendet, welches. einen niedrigen Erweichungspunkt besitzt, unbrennbar ist und eine gute Filmfestigkeit neben Schrumpfvermögen zeigt. Diese Bedingungen erfüllen th ermnoplastische, hochpolymere Vinylverbindungen, wie z. B. Mischpolym@erisate aus P.olyacrylsäurem@ethylester (15 Teile) _ und, _ i#oly-rinylchlorid (85 Teile) oder Mischungen aus Polyvinylaaetat und P@olyvinylalkohiolfo,rmaldehydacetaa oder Polyvinylchlorid nachchloriert./ Diese neuen Produkte besitzen gegenüber den bebekan.nten Celluloseverbindungen den Vorteil der Urbrennbarkeit, keiner Wasseraufnahm-ü u.nd eines niedrigen Erweichungspunktes.Shrink bodies It has been found that new types of shrink bodies, such as bottle caps, tubes, rings, bowl-like or can-like structures, etc., are obtained if the starting material mentioned below is used for the production of these structures. has a low softening point, is incombustible, and exhibits good film strength in addition to shrinkability. These conditions are met by thermoplastic, high polymer vinyl compounds, such as. B. Mischpolym @ erisate from P.olyacrylsäurem@ethylester (1 5 parts) _ and _ i # oly-rinylchlorid (85 parts) or mixtures of Polyvinylaaetat and P @ olyvinylalkohiolfo, rmaldehydacetaa or Polyvinylchlorid nachchloriert./ These new products have compared to the Well-known cellulose compounds have the advantage of primary flammability, no water absorption and a low softening point.

Die neuen Schrumpfkörper lassen sich auf zwei Wegen herstellen. Entweder man überzieht die Tauchformen auf die übliche Weise miteiner Lösung der genannten Polymerisate, evtl. nach Zusatz von Weichmachungs-mitteln, Farb- oder Füllstoffen @o. dgl., verdunstet das Lösungsmittel. und entfernt die gebildetem Schrumpfkörper von dein Formen in bekannter Weise, @od.er man verpreßt die trockenen Pulver unter Anwendung von Druck und Wärme zu den gewünschten Gegenständen.The new shrink bodies can be produced in two ways. Either the dipping forms are coated in the usual way with a solution of the aforesaid Polymers, possibly after the addition of plasticizers, dyes or fillers @O. Like., the solvent evaporates. and removes the shrink body that has formed from your molding in a known way, @ or you press the dry powder under Applying pressure and heat to the objects you want.

Die auf die eine oder andere Art erhaltenen Schrumpfkörper, beispielsweise Flaschenkapseln, werden nun erwärmt, z. B. durch Einbringen meinen geheizten Raum, und im warmen Zustand unter Aufiveiten mit_deLa über den zu ,c#jnden Flaschenhals gezogen. Die Kapseln schrumpfen dann auf ihre ungedehLte Größe zurück und legen sich dabei eng dem Flaschenhals an.The shrink bodies obtained in one way or another, for example Bottle caps are now heated, e.g. B. by bringing in my heated room, and in the warm state under Aufiveiten mit_deLa about the to, c # jnd bottleneck drawn. The capsules then shrink back to their unstretched size and lay close to the neck of the bottle.

Es ist aber auch möglich, die Kapseln im gedehnten Zustand, also z. B. über eine Dehnungsform gequetscht, ;auf Zimmertemperatur abzukühlen. Bei dieser Temperatur befinden sie sich in einem m@etastabilen Zustand, in welchem sie ihre geweitete Form unverändert beibehalten,- leicht von- der Dehnungsform entfernt werden können und so versandfähig sind. Nach losem Überstülpen- über die zu verschließenden Gefäße wird dann durch neues Erwärmen auf die Dehnungstemperatur unter Zerstörung des metastabilen Zustandes die Kontraktionskraft wieder ausg,el@öst, wobei die Kapseln zum engen Anliegen an den Flasche:nUals kommen. Beispiele i. Aus seiner Mischung vorn i 5 Teilen Polyacrylsäurem!e@thylester und 85 Teilern Bolyvinylchlorid wird bei etwa 5o" und aoo Atü eine Kapsel gepreßf üncT-näc#dem Erkalten aus der Form. gewonnen. Diese Kapsel wird in einem Wärmeschrank oder in Wasser von q.o bis 5o° erweicht, mit der Hand auf etwa arpe ihres Durchmessers ausgeweitet und noch warm über einen Flaschenhals gezogen. Darauf legt sie sich in der Wärme sofort an. L. Eine Tauchform wird. in einerl farbig-en Lack aus 3o GewichtsteBeri. Mischpolyme 'sat .aus P;olyvinylacetat ün$ `Pölyvinylalkof>a aldehydacetal und 7o GewichtsMüri 11tZla chloarid getaucht und das Lösungsriri @@i tel. r. trockener Luft verdunstet. Die gebildete-, sei kann unbeschädigt von der Form .abge"=-- rollt werden. Sie wird nun in der Wärme geweitet, was z. B. auf einfache Art durch Überquetschen auf einen erwärmten, dickeren Dorn geschieht. l\Tach Abkühlen auf Zimmertemperatur -kann -die Kapsel leicht wieder vom Dorn abgenommen werden, behält ihre. geweitete Form bei und ist so versandfähig. ,Vom Verbraucher wird die Kapsel über den @@iu verschließenden Flaschenhals lose gestülpt id durch Eiwärmen auf q.o bis 5o° zum iengen Aufschrumpfen gebracht.But it is also possible to use the capsules in the stretched state, so z. B. squeezed over a stretching mold, cool to room temperature. At this temperature they are in a m @ eta stable state in which they retain their expanded shape unchanged - can easily be removed from the stretched shape and can thus be shipped. After loosely slipping over the vessels to be closed, the force of contraction is again released by re-heating to the expansion temperature, destroying the metastable state, whereby the capsules come to rest tightly on the bottle: nUals. Examples i. From its mixture of 5 parts of polyacrylic acid methyl ester and 85 parts of polyvinyl chloride, a capsule is pressed from the mold at about 50 "and aoo air after cooling. This capsule is placed in a heating cabinet or in water from qo Softened to 50 °, widened by hand to about half of its diameter and pulled over the neck of a bottle while still warm. Then it immediately lies in the warmth Paint from 3o weight steeri. Mixed polymer 'sat .from P; olyvinylacetate from $ `polyvinylalcohol> a aldehyde acetal and 7o weight Müri 11tZla chloarid dipped and the solution riri @@ i tel. r. evaporates in dry air. The educated, may be undamaged from the form .abge "= - be rolling. It is now expanded in the warmth, which z. B. happens in a simple way by squeezing on a heated, thicker mandrel. Once it has cooled down to room temperature, the capsule can easily be removed from the mandrel, it retains its. widened form and can be shipped. The consumer puts the capsule loosely over the neck of the bottle that closes the @@ iu bottle and is made to shrink tightly by heating the egg to qo to 5o °.
