Description

Verfahren zum Verkleben von Polyterephthalatfolien Aufgabe der Erfindung ist es, ein Verfahren anzugeben, Polyterephthalatfolien so zu verkleben, daß eine hohe Festigkeit der Klebestellen gegeben ist.Process for gluing polyterephthalate films The object of the invention is to specify a method of gluing polyterephthalate films so that a high strength of the glued joints is given.

Zum Verkleben von Polyterephthalatfolien sind bereits verschiedene Klebemittel bekannt, jedoch läßt sich mit den üblichen Klebern speziell für besondere Verwendungszwecke, z. B. bei der Herstellung von Kunstfolienkondensatoren, keine ausreichende Festigkeit der Verklebung erzielen. There are already various options for gluing polyterephthalate films Known adhesive, but can be used with the usual adhesives especially for special Uses, e.g. B. in the production of plastic film capacitors, none achieve sufficient strength of the bond.

Polyterephthalatfolien können auch miteinander verschweißt werden. Hierfür sind jedoch hohe Temperaturen erforderlich. Durch Benutzung eines zusätzlichen Klebemittels läßt sich die notwendige Schweißtemperatur herabsetzen. Als Klebemittel für derartige Heißverklebungen ist Benzylalkohol bekannt. Polyterephthalate foils can also be welded together. However, this requires high temperatures. By using an additional The necessary welding temperature can be reduced by means of an adhesive. As an adhesive Benzyl alcohol is known for such hot bonds.

Eine wesentlich erhöhte Festigkeit der Klebestellen erzielt man bei einem Verfahren zum Verkleben von Polyterephthalatfolien, das erfindungsgemäß darin besteht, daß ein Gemisch von Benzylalkohol und Phenol als Klebemittel verwendet wird und die Verklebung bei einer Temperatur von etwa 180 bis 2000 C vorgenommen wird. A significantly increased strength of the glued areas is achieved with a method for gluing polyterephthalate films according to the invention therein consists in using a mixture of benzyl alcohol and phenol as an adhesive and the bonding is carried out at a temperature of about 180 to 2000 C. will.

Als besonders günstig hat sich ein Klebemittel erwiesen, das aus 5 Teilen Phenol und 1 Teil Benzylalkohol besteht. An adhesive that consists of 5 parts phenol and 1 part benzyl alcohol.

Die Verklebung läßt sich so herstellen, daß eine der zur verbindenden Polyterephthalatfolien an der zu verbindenden Stelle dünn mit dem Kleber bestrichen wird, worauf die zweite Folie daraufgelegt und die Verklebung durch leichtes Aufdrücken eines auf eine Temperatur von 180 bis 2000 C erhitzten Körpers hergestellt wird. The bond can be produced in such a way that one of the to be connected Polyterephthalate films thinly coated with the adhesive at the point to be connected whereupon the second film is placed on top and the adhesive is applied by gently pressing it on a body heated to a temperature of 180 to 2000 C is produced.

Bei Zerreißproben an derart heißverklebten Folienstreifen von 15 mm Breite, 20 Dicke und etwa 2 mm Uberlappung war die Verklebung so fest, daß die Streifen nicht an der Klebestelle, sondern im Material rissen, wohingegen bei gleichen Mustern, jedoch nach den bekannten Verfahren verklebt bzw. verschweißt, sich die Klebestelle öffnet. Die zur Verklebung in Frage kommenden Polyterephthalsäureester sind z. B. in Transactions of the Faraday Society, 1950, Bd. 46. In tensile tests on such heat-bonded film strips of 15 mm wide, 20 mm thick and about 2 mm overlap, the bond was so strong that the Stripes tore in the material rather than at the glue point, whereas with the same Patterns, but glued or welded according to the known method, the Glue opens. The polyterephthalic acid esters that can be used for bonding are z. B. Transactions of the Faraday Society, 1950, vol. 46.
