Abstract
Description
Die Erfindung betrifft eine Trennfolie für Bahnen, Planen und Streifen im Bereich der Fugen-, Dach- und Fassadenabdichtung, wobei die Bahnen, Planen und Streifen jeweils wenigstens aus einer Oberschicht und einer selbstklebenden Unterschicht bestehen, wobei wiederum die Unterschicht mit einer Trennfolie abgedeckt ist.The The invention relates to a release film for webs, tarpaulins and strips in the field of joint, roof and facade waterproofing, where the sheets, tarpaulins and strips each of at least one upper layer and one self-adhesive lower layer, in turn, the lower layer covered with a release film.
Bahnen,
Planen und Streifen spielen bei der Abdichtung von Fugen, Dächern und
Fassaden eine wesentliche Rolle, wobei hinsichtlich des Standes der
Technik beispielsweise auf die Druckschriften
Diese Bahnen, Planen und Streifen bestehen jeweils wenigstens aus einer Oberschicht (Dichtschicht) und einer Unterschicht (Haftschicht zum Unterbau), wobei die Unterschicht zunehmend selbstklebend ausgerüstet wird. Die Oberschicht kann dabei mehrschichtig gestaltet sein, insbesondere unter Ausbildung einer Mittelschicht mit eingebettetem Festigkeitsträger, beispielsweise in Form eines Glasgeleges, Glasvollgewebes oder eines Geleges aus einem ausgeschrumpften Polyester. Die Oberschicht besteht vorzugsweise aus dem witterungsbeständigen Ethylen-Propylen-Dien-Mischpolymerisat (EPDM). Die Unterschicht besteht zumeist aus Bitumen oder Elastomerbitumen, wobei die Einmischung eines klebrigen Harzes die selbstklebende Eigenschaft auslöst. Während der Lagerung und des Transportes wird die selbstklebende Unterschicht mit einer Trennfolie abgedeckt, die dann vor der Verlegung vollständig oder partiell mittels Perforation entfernt wird. Hinsichtlich werkstoffmäßiger Details wird insbesondere auf die oben genannte Patentliteratur verwiesen.These Lanes, tarpaulins and strips each consist of at least one Upper layer (sealing layer) and a lower layer (adhesive layer to the Substructure), whereby the lower layer is increasingly self-adhesive. The upper layer can be designed multi-layered, in particular forming a middle layer with embedded strength member, for example in the form of a glass fabric, glass fiber fabric or a Geleges of one shredded polyester. The upper layer is preferably from the weather-resistant Ethylene-propylene-diene copolymer (EPDM). The lower class consists mostly of bitumen or Elastomerbitumen, the interference of a sticky resin which triggers self-adhesive property. During the Storage and transport will be the self-adhesive underlayer covered with a release liner, which then completely or before laying partially removed by means of perforation. Regarding material details reference is made in particular to the abovementioned patent literature.
Nach dem bisherigen Stand der Technik war eine Perforation nur dann möglich, wenn die rückseitige Trennfolie mit Messer oder Cutter vor der Verklebung eingeschnitten wurde. Diese Vorgehensweise ist sehr kritisch und nur unter hohem Risiko einer Beschädigung der Bahnen, Planen und Streifen möglich. Die Folge war häufig, dass beispielsweise ein Streifen an mehreren Stellen perforiert war, was schließlich zu Undichtigkeiten geführt hatte.To The prior art, a perforation was only possible if the back Cutting foil cut with a knife or cutter before bonding has been. This approach is very critical and only high Risk of damage the tracks, tarpaulins and stripes possible. The result was often that for example, a strip was perforated in several places, what finally led to leaks would have.
Im Hintergrund der hier geschilderten Problematik besteht die Aufgabe der Erfindung darin, eine Trennfolie für selbstklebende Bahnen, Planen und Streifen bereit zu stellen, die es erlaubt, ohne scharfe Gegenstände wie Messer, Schere usw. eine in Längsrichtung der oben genannten Flächenwaren sauber verlaufende Perforation durchzuführen, verbunden mit einer gezielten Anfangsperforation bzw. einem Anriss der Trennfolie.in the Background of the problem described here is the task the invention therein, a release film for self-adhesive webs, tarpaulins and To provide stripes that allow it, without sharp objects like Knife, scissors, etc. one in the longitudinal direction The above items were clean to perform a continuous perforation associated with a targeted initial perforation or a tear the release film.
Gelöst wird diese Aufgabe dadurch, dass die Trennfolie wenigstens auf der Seite, die der selbstklebenden Unterschicht zugewandt ist, mit einer zusätzlichen Trennschicht versehen ist.Is solved this task in that the release film at least on the side, which faces the self-adhesive underlayer, with an additional Separating layer is provided.
Die Trennschicht besteht insbesondere aus Silikon, das vorzugsweise lösemittelfrei ist.The Separating layer consists in particular of silicone, preferably solvent-free is.
Die Trennschicht kann auch aus einem Polyfluorkohlenwasserstoff, insbesondere Polytetrafluorethylen (Teflon), bestehen.The Separating layer can also be made of a polyfluorohydrocarbon, in particular Polytetrafluoroethylene (Teflon), consist.
Die Trennschicht kann in Bezug auf die Trennfolie auch beidseitig aufgebracht werden, vorzugsweise durch Aufdampfung.The Separating layer can also be applied on both sides in relation to the release film be, preferably by evaporation.
Als
Trennfolie kommen insbesondere folgende Werkstoffe zum Einsatz:
Polyethylen
(PE)
High Density Polyethylen (HD-PE)
Low Density Polyethylen
(LD-PE)
Polypropylen (PP)
Polyester (PET)
Ethylen-Vinylacetat
(EVA; ein Copolymer)As a release film, the following materials are used in particular:
Polyethylene (PE)
High density polyethylene (HD-PE)
Low Density Polyethylene (LD-PE)
Polypropylene (PP)
Polyester (PET)
Ethylene vinyl acetate (EVA, a copolymer)
Auch Mischpolymere der vorgenannten Art sind einsetzbar, wobei vorzugsweise auf eine Mischfolie von Polyester und Polypropylen (PETP) verwiesen wird.Also Mixed polymers of the aforementioned type can be used, preferably referred to a mixed film of polyester and polypropylene (PETP) becomes.
Die Stärke der Trennfolie beträgt 20 bis 70 μm, vorzugsweise 30 bis 40 μm.The Strength the release film is 20 to 70 μm, preferably 30 to 40 microns.
Die Trennfolie kann für UV-Strahlung durch Pigmente undurchlässig ausgerüstet sein. Auch sind farblos transparente oder eingefärbte Versionen möglich. Zudem sind die vorgenannten Folienwerkstoffe recycelfähig.The Release film can for UV radiation impermeable by pigments. Also are colorless transparent or colored Versions possible. In addition, the aforementioned film materials are recyclable.
Die Stärke der Trennschicht ist kleiner als die der Trennfolie, und zwar zumeist im Bereich von 1 bis 5 μm.The Strength the release layer is smaller than that of the release film, and usually in the range of 1 to 5 μm.
Die Erfindung wird nun anhand eines Ausführungsbeispieles unter Bezugnahme auf schematische Zeichnungen erläutert. Es zeigen:The Invention will now be described with reference to an embodiment with reference explained on schematic drawings. Show it:
Bei Bedarf kann man auch die gesamte Trennfolie entfernen.at Demand you can also remove the entire release film.
