Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • a film made of thermoplastic material is used as the carrier film.
  • This carrier film can advantageously consist at least predominantly of polyethylene terephthalate.
  • the carrier film used consists of several interconnected individual films.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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).
  • PVDF polyvinylidene fluoride
  • 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.
  • 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.
  • 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.
  • PVF polyvinyl fluoride
  • 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.
  • the composite plastic film produced had the following mechanical properties:
  • This composite plastic film also has a tear strength which is higher than the sum of the tear forces of the individual films.
  • the composite film produced according to the invention can be produced efficiently and used for sails and sail windows or for similar purposes.

Abstract

Pour fabriquer une feuille composée de matière plastique résistant aux rayons UV, on joint de manière continue, à l'aide d'un adhésif à base de polyuréthane ou d'une résine polyesterimide, une feuille de support en matière thermoplastique, en particulier du polyéthylènetéréphtalate, servant de feuille continue avec deux feuilles de couverture en une matière résistant aux rayons UV, par exemple du polyvinylidènefluorure ou du polyvinylfluorure. Les couches de couverture et/ou l'adhésif contiennent des substances qui absorbent les rayons UV. La feuille de support en polyéthylènetéréphtalate, par exemple, dont la matière ne résiste pas aux rayons UV, est ainsi protégée contre les rayons UV. Cette feuille composée a comme avantage supplémentaire une grande résistance à la propagation du déchirement, supérieure à la somme des forces de résistance à la propagation du déchirement des différentes feuilles constituant la feuille composée, prises individuellement. Elle peut donc, en une présentation de 0,08 à 0,03 mm d'épaisseur, servir avantageusement de matière pour fabriquer des voiles ou des fenêtres de voiles.
