Description
Verfahren zur Herstellung von im Hochfrequenz-oder Ultra-Hochfrequenzfeld verformbaren thermoplastischen Vorder- und Hinterkappenmaterialien Es ist bekannt, daß Kunststoffe mit hinreichenden dielektrisehen Verlusten, beispielsweise Polyvinylchlorid, Polyamide, Celluloseacetat u.a., im Hochfrequenzfeld oder Ultra-Hochfrequenzfeld erwärmt und gegebenenfalls miteinander verschweißt werden können. Im Gegensatz zu anderen Beheizungsarten wird bei der dielektrischen Erwärmung die zur Verfügung stehende Energie über den ganzen Querschnitt des zu erwärmenden Kunststoffes absorbiert und in Wärme umgesetzt, sodaß eine sehr schnelle und vor allem gleichmäßige Erwärmung stattfindet. Process for the production of in the high-frequency or ultra-high-frequency field deformable thermoplastic front and rear cap materials It is known that plastics with sufficient dielectric losses, for example polyvinyl chloride, Polyamides, cellulose acetate, etc., in the high-frequency field or ultra-high-frequency field can be heated and optionally welded together. In contrast to Other types of heating are available for dielectric heating standing energy is absorbed over the entire cross-section of the plastic to be heated and converted into heat, so that very rapid and, above all, even heating takes place.
Aus der DT-PS 1 104 389 ist weiterhin bekannt, Schuhwerkteile mit Hilfe eines thermoplastischen Materials und eines Hochfrequenzfeldes zu verkleben, und zwar derart, daß die Laufsohle mit einer Paste bestrichen oder mit einem ausgestanzten, gleich großen Stück eines thermoplastischen Stoffes beschichtet bzw. kaschiert wird, wobei die Innenelektrode auf dem Leisten und die Außenelektrode auf dem Kissen der Klebepresse aufliegt.From DT-PS 1 104 389 it is also known to have footwear parts Gluing with the help of a thermoplastic material and a high-frequency field, in such a way that the outsole is coated with a paste or with a punched out, a piece of a thermoplastic material of the same size is coated or laminated, the inner electrode on the last and the outer electrode on the pad of the Gluing press rests.
Schließlich wird in der britischen Patentschrift 1 118 439 noch ein Verfahren zum Trocknen und/oder Aushärten von Hinterkappen beschrieben, bei welchem die Schuhe oder Schuhteile auf einem bewegten Band durch eine Heizkammer geführt werden, in welcher sich mindestens ein Magnetron zur Erzeugung von Mikrowellen befindet. Durch die Erwärmung im Hochfrequenzfeld kann die Trocken- bzw. Aushärtungszeit auf 15, maximal 30 Sekunden herabgesetzt werden, also auf etwa 1/loo und weniger der früher für die gleichen Vorgänge benötigten Zeit.Finally, in British Patent 1,118,439, another is used Method for drying and / or curing of heel caps described, in which the shoes or shoe parts are guided through a heating chamber on a moving belt in which there is at least one magnetron for generating microwaves. Due to the heating in the high-frequency field, the drying or curing time can increase 15 seconds or a maximum of 30 seconds, i.e. to about 1 / loo and less that time previously required for the same operations.
Wie sich jedoch gezeigt hat, zeigen die bisher bekanntgewordenen Verfahren zum Erwärmen von Schuhteilen, insbesondere Verformen von thermoplastischen Vorder- und Hinterkappen im Hochfrequenzfeld (HF) oder Ultra-Hochfrequenzfeld (UHF) noch verschiedene Mängel, sodaß sie sich in der Praxis noch nicht voll durchgesetzt haben. Ein besonderer Nachteil wird beispielsweise darin gesehen, daß es häufig zu Durchschlägen und damit zu Überhitzungen kommt, die sowohl zu-Lochbildungen behandelten Schuhmaterial als auch Verbrennungen und Verkohlungen in der Leistenform führen können. Außerdem führt die unerwünschte Überhitzung oft zur Abspaltung schädlicher Stoffe im Thermoplasten, z.B. von HC1.However, as has been shown, the methods that have become known so far show for heating shoe parts, especially deforming thermoplastic front and heel caps in the high frequency field (HF) or ultra high frequency field (UHF) still various shortcomings, so that they have not yet fully asserted themselves in practice. A particular disadvantage is seen, for example, in the fact that breakdowns occur frequently and thus overheating occurs in the shoe material treated with holes as well as burns and charring in the shape of the groin. aside from that the undesired overheating often leads to the splitting off of harmful substances in the thermoplastic, e.g. from HC1.
Überraschenderweise können nun die vorerwähnten Schwierigkeiten in einfacher Weise dadurch beseitigt werden, daß die als Vorder- und Hinterkappen zu verarbeitenden thermoplastischen Massen mit Isolierstoffen, beispielsweise alpha-Aluminiumoxyd, versehen werden. Dadurch werden Überschläge bei den zur Erzeugung des Hochfrequenz- oder Ultrahochfrequenzfeldes erforderlichen Spannungen verhindert und die befürchteten Verfärbungen bzw. Beschädigungen in den Schuhmaterialien bzw. Leistenformen unterbleiben. Der prozentuale Anteil des Isolierstoffes in-dem eingesetzten thermoplastischen Material, bezogen auf Festkörpergehalt, kann bis zu 50 Gew.# betragen. Er sollte mindestens bei lo Gew. liegen, wird aber vorteilhafterweise auf 20-40 Gew.% eingestellt.Surprisingly, the aforementioned difficulties in can easily be eliminated by the fact that the front and rear caps are too processing thermoplastic masses with insulating materials, for example alpha-aluminum oxide, be provided. This causes flashovers in the high-frequency or ultra-high frequency field prevents the voltages required and the feared There are no discolorations or damage to the shoe materials or lasts. The percentage of insulating material in the thermoplastic used Material, based on solids content, can be up to 50 wt. #. He should are at least 10% by weight, but is advantageously set to 20-40% by weight.
Andere geeignete Isolierstoffe sind beispielsweise keramische dielektrische Massen wie magnesiumsilikathaltige oder titanhaltige Massen. Auch können Kunststoffe mit geeigneten dielektrischem Verlustfaktor, z.B. Polystyrol, eingesetzt werden.Other suitable insulating materials are, for example, ceramic dielectric Masses such as masses containing magnesium silicate or titanium. Plastics can also with a suitable dielectric loss factor, e.g. polystyrene, can be used.
Zur Herstellung des Vorder- und Hinterkappenmaterials -können alle thermoplastischen, polare Gruppen bildende Kunststoffe eingesetzt werden, insbesondere PVC und polare Gruppen enthaltende kautschukartige Massen wie solche aus Butadien - Acrylnitril. Die Isolierstoffe können sowohl in wässrige Dispersionen der Thermoplaste eingetragen werden als auch in geschmolzene Thermoplaste. Die Isolierstoffe enthaltenden Massen werden dann entweder mittels Imprägnierung, Walzenauftrag, Extrusion oder anderen bekannten Verfahren auf einen Träger aufgebracht oder ohne Trägermaterial zu einer Bahn oder einem Schlauch verarbeitet.For the production of the front and back cap material, everyone can thermoplastic, polar group-forming plastics are used, in particular Rubber-like compositions containing PVC and polar groups, such as those made from butadiene - acrylonitrile. The insulating materials can be used in aqueous dispersions of thermoplastics be entered as well as in molten thermoplastics. Containing the insulating materials Masses are then either by means of impregnation, roller application, extrusion or other known methods applied to a carrier or without a carrier material processed into a web or a tube.
Nch einer anderen Ausführungform der Erfindung kann das Vorder- und Hinterkappenmaterial auch in der Weise hergestellt werden, daß zunächst in an sich bekannter Weise eine thermoplastische Bahn mit oder ohne Trägermaterial hergestellt wird, die anschließend mit einer Isolierschicht versehen wird. Die Isolierschicht kann ein- oder beidseitig aufgetragen werden und besteht wie die Tragschicht aus einem Thermoplasten mit polaren Gruppen. Von letzterer unterscheidet sie sich jedoch dadurch, daß sie bis zu 50 Gew. Isoliermaterial, bezogen auf Festkörpergehalt der Isolierschicht, enthält.In another embodiment of the invention, the front and back Back cap material can also be produced in such a way that initially in per se a known way a thermoplastic web is produced with or without a carrier material which is then provided with an insulating layer. The insulating layer can be applied on one or both sides and consists of the same as the base layer a thermoplastic with polar groups. However, it differs from the latter in that they have up to 50 wt. Insulating material, based on the solids content of the Insulating layer.
Das erfindungsgemäß hergestellte Vorder- und Hinterkappenmaterial kann in an sich bekannter Weise auch ein- oder beidseitig mit einem Klebstrich versehen werden, wobei es für die Erwärmung im HF oder UHF wesentlich ist, daß auch der Klebanstrich einen hinreichend hohen dielektrischen Verlust aufweist. Geeignete Klebstoffe sind beispielsweise Polyvinylacetat und dessen Copolymere.The front and back cap material made in accordance with the invention can also be provided with an adhesive line on one or both sides in a manner known per se , whereby it is essential for the heating in the HF or UHF that the adhesive coat is also used has a sufficiently high dielectric loss. Suitable adhesives are for example polyvinyl acetate and its copolymers.
Mittels der Klebstriche kann das KOppenmaterial nach Aktivierung mit dem Oberleder bzw. dem Innenfutter unter Druck verklebt werden.By means of the adhesive lines, the head material can also be used after activation the upper leather or the inner lining are glued under pressure.
Nach einer weiteren Verfahrensvariante kann das erfindungsgemäß hergestellte Kappenmaterial auch einseitig mit einer wildlederähnllchen oder ledernen Abdeckung versehen werden, und zwar derart, daß die Tragschicht bzw. Isolierschicht mit der vorerwähnten Abdeckschicht versehen oder verklebt wird.According to a further variant of the method, that produced according to the invention can Cap material also on one side with a suede-like or leather cover are provided, in such a way that the support layer or insulating layer with the the aforementioned cover layer is provided or glued.
