Abstract

A plastic composite film resistant to UV radiation is manufactured by continuously bonding an endless supporting film made of a thermoplastic material, in particular polyethylene terephthalate, to two covering films made of a material resistant to UV radiation, such as polyvinylidene fluoride or polyvinyl fluoride, using an adhesive based on polyurethane or a polyesterimide resin. The covering films and/or the adhesive contain materials which absorb UV radiation. The polyethylene terephthalate supporting film, for example, which is made of a material attacked by UV radiation, is thereby protected against UV radiation. A further advantage of this composite film is its high tear strength, which is greater than the sum of the tear strengths of the individual films used to manufacture the composite film. The composite film can therefore be used advantageously in thicknesses of 0.08 to 0.03 mm as a material for making sails or sail windows.

Technisches GebietTechnical field
Die Erfindung betrifft ein Verfahren zum Herstellen eine Verbundfolie, bei dem eine Trägerfolie zumindest an eine Oberfläche durch Klebung mit einer Deckfolie verbunden ist, die zumindest überwiegend aus Polyvinylidenfluorid oder Po- lyvinylfluorid besteht. Sie betrifft ferner eine vorteilhaf¬ te Verwendung der so hergestellten Verbundfolie.The invention relates to a method for producing a composite film, in which a carrier film is connected at least to one surface by adhesive bonding to a cover film which at least predominantly consists of polyvinylidene fluoride or polyvinyl fluoride. It also relates to an advantageous use of the composite film produced in this way.
Stand der TechnikState of the art
Ein Verfahren dieser Art ist aus dem EP-A1-164766 bekannt, bei dem - gemäß den Beispielen 5 bis 12 - eine Folie aus Polyvinylidenfluorid mittels eines Klebers auf Basis von Polyvinylacetat mit einer Folie aus einem polaren Kunststoff verbunden wird.A method of this type is known from EP-A1-164766, in which - according to Examples 5 to 12 - a film made of polyvinylidene fluoride is connected to a film made of a polar plastic by means of an adhesive based on polyvinyl acetate.
Das dabei im Detail beschriebene Klebeverfahren ist insbe¬ sondere durch die langen Trockungszeiten der eingesetzten Kleberlösung verhältnismäßig aufwendig und für eine Durch¬ führung im Großen wenig geeignet.The adhesive process described in detail is relatively complex, in particular due to the long drying times of the adhesive solution used, and is unsuitable for large-scale implementation.
Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt nun zunächst die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art anzugeben, das ohne großen Aufwand rationell durchführbar ist.The invention is based on the object of specifying a method of the type mentioned at the outset which can be carried out efficiently without great effort.
Die der Erfindung zugrunde liegende Aufgabe wird in dem er- findungsgemäßen Verfahren gelöst, das dadurch gekennzeichnet ist, daß die Trägerfolie und zwei Deckfolien in Form von Endlosbahnen eingesetzt werden, die kontinuierlich mittels eines Klebers auf Basis von Polyurethan oder eines Poly esterimidharzes verbunden werden und wobei die Deckfolie und/oder der Kleber UV-Strahlung absorbierende Stoffe ent halten. Dabei sind die Dicken der eingesetzten Deckfolie vorteilhaft jeweils kleiner als die der eingesetzten Trä gerfolie.The object on which the invention is based is achieved in the method according to the invention, which is characterized in that the carrier film and two cover films are used in the form of endless webs which are continuously produced by means of of an adhesive based on polyurethane or a polyester esterimide resin and wherein the cover film and / or the adhesive contain UV radiation-absorbing substances. The thicknesses of the cover film used are each advantageously smaller than that of the carrier film used.
Gemäß einer vorteilhaften Ausgestaltung des erfindungsge mäßen Verfahrens wird als Trägerfolie eine Folie aus thermo plastischem Material eingesetzt. Diese Trägerfolie kan dabei vorteilhaft zumindest überwiegend aus Polyäthylen terephthalat bestehen.According to an advantageous embodiment of the method according to the invention, a film made of thermoplastic material is used as the carrier film. This carrier film can advantageously consist at least predominantly of polyethylene terephthalate.
Nach einer anderen vorteilhaften Ausgestaltung des erfin dungsgemäßen Verfahrens besteht die eingesetzte Trägerfoli aus mehreren miteinander verbundenen Eiπzelfolien.According to another advantageous embodiment of the method according to the invention, the carrier film used consists of several interconnected individual films.
Die Erfindung betrifft ferner eine Verwendung der erfin dungsgemäß hergestellten Verbundfolie, die dadurch gekenn zeichnet ist, daß sie mit einer Dicke im Bereich von 0,0 bis 0,3 mm als Material für Segel oder Segelfenster verwen det wird.The invention further relates to a use of the composite film according to the invention, which is characterized in that it is used as a material for sails or sail windows with a thickness in the range of 0.0 to 0.3 mm.
Die durch . das erfinduπgsgemäße Verfahren hergestellte Ver bundfolie kann nun bei entsprechender Abstimmung der Dicke der einzusetzenden Folien und der Menge der die UV-Strahlun absorbierenden Stoffe in rationeller Weise erzeugt und al gegen UV-Strahlung stabile Folie mit hoher Witterungsbe ständigkeit eingesetzt werden. So wird nämlich z.B. eine au Polyäthylenterephthalat bestehende Trägerfolie, dere Material gegen UV-Strahlung nicht stabil ist, gegen UV Strahlung geschützt. Dabei hat sich ergeben, daß insbeson dere mit einer solchen Trägerfolie Verbundfolien hergestell werden können, die speziell deshalb vorteilhaft als Materia für Segel und Segelfenster verwendbar sind, weil sie eine überraschend hohe Weiterreißfestigkeit aufweisen. Bei eine solchen Verwendung ist nämlich - wegen der Verarbeitung des Segelmaterials durch Herstellung von Nähten sowie der For¬ derung, daß das Segelmaterial nach Perforationen beim Ge- brauch möglichst nicht weiterreißen soll - eine hohe Wei¬ terreißfestigkeit wichtig.By . the method according to the invention, the composite film produced can now be produced in a rational manner with appropriate coordination of the thickness of the films to be used and the amount of substances absorbing the UV radiation, and a film which is stable against UV radiation and has a high resistance to weathering can be used. For example, a carrier film made of polyethylene terephthalate, the material of which is not stable against UV radiation, is protected against UV radiation. It has been found that, in particular, composite films can be produced with such a carrier film, which are therefore particularly advantageous as materials can be used for sails and sail windows because they have a surprisingly high tear resistance. With such a use, a high tear resistance is important because of the processing of the sail material by producing seams and the requirement that the sail material should not tear further after perforations when used.
Die nach DIN 53363 bestimmten Werte der Weiterreißfestigkeit an der nach dem erfindungsgemäßen Verfahrens hergestellten Verbundfolie sind nun überraschenderweise höher als die Summe der an den Einzelfolien gemessenen Weiterreißkräfte. Für einen bestimmten Mindestwert der Weiterreißkraft kann daher die als Verbundmaterial aufgebaute erfindungsgemäße Kunststoffolie nicht unwesentlich dünner und daher leichter ausgelegt werden als eine etwa gleichwertige Monofolie.The values of the tear propagation strength determined according to DIN 53363 on the composite film produced by the method according to the invention are now surprisingly higher than the sum of the tear forces measured on the individual films. For a certain minimum value of the tear strength, the plastic film according to the invention constructed as a composite material can therefore be designed not insignificantly thinner and therefore lighter than an approximately equivalent monofilm.
Einige Wege zur Ausführung der ErfindungSome ways of carrying out the invention
Beispiel 1:Example 1:
Zur Herstellung der Verbund-Kunststoffolie wird eine 0,125 mm dicke Folie aus Polyäthyleπenterephthalat (PETP) als Kernschient auf beiden Seiten mit jeweils einer 0,012 mm dicken Deckschicht-Folie aus Polyvinylidenfluorid (PVDF) kontinuierlich durch Kaschierung verbunden. Für die Ka¬ schierung kommt ein Polyurethan-Zweikomponentenkleber zum Einsatz, dem 1,5 Gew.% (Festkörper) des UV-Absorbers "Tinnu- vin 326" der Firma Ciba-Geigy AG, Basel, zugesetzt ist. In einer Kaschiermaschine wird die PETP-Folie zunächst auf bei¬ den Seiten mit einem Auftrag von etwa 10 g/mz dieser Kleberformulierung versehen, das Lösungsmittel des Kleber¬ auftrags in einer Heizzone bei 120 - 130° C abgetrocknet und schließlich in einem beheizten Kalander bei ca. 100° C mit den beiden PVDF-Deckfolien verbunden, die vorher verklebe- seitig zur Verbesserung ihrer Verklebbarkeit einer Nieder¬ druckplasmabehandlung unterworfen wurden. Die Produktioπs- geschwindigkeit dieser kontinuierlichen Kaschierung beträgt dabei 6 - 7 m/min und der Liniendruck im beheizten Kalander etwa 20 N/mm.To produce the composite plastic film, a 0.125 mm thick film made of polyethylene terephthalate (PETP) is continuously bonded as a core rail on both sides with a 0.012 mm thick cover layer film made of polyvinylidene fluoride (PVDF). A two-component polyurethane adhesive is used for the lamination, to which 1.5% by weight (solids) of the UV absorber "Tinnuvin 326" from Ciba-Geigy AG, Basel, has been added. In a laminator the PETP film is first provided on bei¬ the sides at a coverage of about 10 g / m z of the adhesive formulation, the solvent of the Kleber¬ contract in a heating zone at 120 - 130 ° C and finally dried in a heated calender at approx. 100 ° C with bonded to the two PVDF cover foils which had previously been subjected to a low-pressure plasma treatment on the adhesive side in order to improve their bondability. The production speed of this continuous lamination is 6 - 7 m / min and the line pressure in the heated calender is about 20 N / mm.
An der so erhaltenen Verbund-Kunststoffolie wurden jeweils in (Folienbahnen)-Längsrichtung (L) und senkrecht dazu, in Querrichtung (Q) die Reißfestigkeit in N/mm2 (nach DIN 53857) und die Weiterreißkraft (WRK-Verbund) in N/mm (nach DIN 53363) bestimmt. Außerdem wurde die Summe der an den drei zum Verbundfolienaufbau dienenden Einzelfolien gemes¬ senen Weiterreißkräfte bestimmt (5: WRK). WRK-Verbund und Σ. WRK werden dann auf die Verbundfoliendickeneinheit ermittelt und gegenübergestellt.The tensile strength in N / mm 2 (according to DIN 53857) and the tear strength (WRK composite) in N / were measured on the composite plastic film thus obtained in the (film webs) longitudinal direction (L) and perpendicular to it, in the transverse direction (Q). mm (according to DIN 53363). In addition, the sum of the tear forces measured on the three individual foils used to build the composite foil was determined (5: WRK). WRK network and Σ. WRK are then determined on the composite film thickness unit and compared.
Dabei ergaben sich folgende Werte:The following values resulted:
L Q Reißfestigkeit-Verbund N/mm2 141 153LQ tear strength composite N / mm 2 141 153
WRK-VerbundWRK network
N/mm 353 382N / mm 353 382
WRK N/mm 222 235WRK N / mm 222 235
Die Summe der Weiterreißkräfte (∑WRK) der Einzelfolien ist also sowohl für die Längs- und die Querrichtuπg erheblich kleiner als die Weiterreißkraft der Verbund-Kunststoffolie (WRK-Verbund). Bei spie l 2 :The sum of the tear forces (∑WRK) of the individual films is therefore considerably lower for both the longitudinal and the transverse direction than the tear force of the composite plastic film (WRK composite). In game 2:
Bei diesem Beispiel sind die eingesetzten Eiπzelfolien ein 0,075 mm dicke PETP-Folie und zwei 0,0125 mm dicke Folien aus Polyvinylfluorid (PVF) der Firma Dupont, einer Qualität, die einen UV-Absorber enthält und die verklebeseitig eine Niederdruckplasma-Vorbehandlung unterworfen wurden.In this example, the individual films used are a 0.075 mm thick PETP film and two 0.0125 mm thick films made of polyvinyl fluoride (PVF) from Dupont, a quality which contains a UV absorber and which have been subjected to a low-pressure plasma pretreatment on the adhesive side.
Die Herstellung der Verbund-Kunststoffolie erfolgt analog wie gemäß Beispiel 1 beschrieben, nur mit dem Unterschied, daß die Kleberformulierung statt einem Polyurethankleber einen Zweiko poneπtenkleber auf Basis eines Polyesteri id- harzes enthält.The composite plastic film is produced analogously to that described in Example 1, with the only difference that the adhesive formulation contains a two-component adhesive based on a polyester resin instead of a polyurethane adhesive.
Die erzeugte Verbund-Kunststoffolie hatte folgende mechani¬ sche Eigenschaften:The composite plastic film produced had the following mechanical properties:
Reißfestigkeit N/mm2 150 173Tear resistance N / mm 2 150 173
WRK-Verbund N/mm 397 354WRK composite N / mm 397 354
∑WRK N/mm 247 307∑WRK N / mm 247 307
Auch diese Verbund-Kunststoffolie zeigt eine Weiterrei߬ kraft, die höher ist als die Summe der Weiterreißkräfte der Einzelfolien.This composite plastic film also has a tear strength which is higher than the sum of the tear forces of the individual films.
Gewerbliche VerwertbarkeitCommercial usability
Die erfindungsgemäß hergestellte Verbundfolie kann rationell hergestellt und für Segel und Segelfenster oder für ähnliche Zwecke verwendet werden. The composite film produced according to the invention can be produced efficiently and used for sails and sail windows or for similar purposes.
