Definitions

  • the invention relates to a method for producing a Foil to create a surface protective layer a profile body, one with a thermosetting Impregnated resin impregnated carrier roll with a layer of lacquer is provided.
  • Such a method is known (DE-A-42 10 528).
  • the film produced by the known method can it is a sheet of paper soaked in melamine resin act on which a layer of one Polyurethane paint is arranged.
  • the film produced by the known method for coating a highly structured Profile body for example one Profile body, which rests on a horizontal surface connect vertical surfaces at an obtuse angle, then the film becomes a strong mechanical Stress, for example exposed to shear.
  • the paint on the outer paint layer of the film Partial areas either completely sheared off or on the Slide film and thus be distributed unevenly.
  • parts of the paint can flake off or it can Micro cracks appear in the paint. In any case, these lead Effects on the lacquer to a weakening or Destruction of the protective layer.
  • the technical problem underlying the invention is the process of making the film too improve so that the film is more resistant to their Further processing will also Weather resistance of the film can be improved.
  • the finished film In the finished film is the condensation resin dried sufficiently so that after pressing on the Profile body is cured.
  • the paint is after Drying also largely hardened.
  • the finished one Foil consists of two homogeneous layers, namely the Carrier film and the lacquer layer, being because of used materials in the border area between the homogeneous layers a mixture of substances and a chemical reaction has taken place between them.
  • the manufactured according to the inventive method Foil is particularly suitable for profile bodies, which constantly exposed to the weather, a long-term Weather resistance.
  • Profile bodies can be molded, for example Profiles for balcony or facade cladding as well pressed boards and molded wood parts, such as chipboard, Trade fiberboard or veneer. But it can also window sills, window profiles, roof elements, Table tops or the like.
  • the chip or fibrous mixture can for example, a non-flowable mixture crushed lignocellulosic particles, such as shredded and dried wood shavings, bagasse fibers and the like, act on a thermosetting binder Thermoset base, such as a melamine or urea formaldehyde Phenol formaldehyde resin, is added.
  • a non-flowable mixture crushed lignocellulosic particles such as shredded and dried wood shavings, bagasse fibers and the like, act on a thermosetting binder Thermoset base, such as a melamine or urea formaldehyde Phenol formaldehyde resin, is added.
  • shredded and dried wood or bagasse fibers fibers of other materials such as glass fibers, Rock wool or asbestos fibers, alone or several the same are mixed with one another, to which corresponding, preferably organic, binders are clogged.
  • a device is shown schematically in the figure, which for the production of the coated film suitable is.
  • the uncoated film which for example from one printed with a pattern Paper exists, is wound on the roller 1.
  • she will deducted from the roller 1 and through with impregnating resin filled container 2 pulled.
  • the soaked film is in the dryer 3 at temperatures of 100 - 180 degrees Celsius dried so that it leaves the dryer still contains 8-20% by weight of volatile constituents.
  • the film After painting, the film is replaced by the second Dryer run where they are at temperatures from 100 - 180 Degrees Celsius is dried so that it at Leave this dryer 2 - 20, preferably 4 - Contains 10% by weight of volatile components.
  • the dryer has a chemical reaction, i.e. a cross-linking between the impregnation resin and the lacquer.
  • the done coated film is wound on the drum 6.
  • the paint can also be a lubricant, for example a Paraffin.
  • the lubricant migrates when it dries to the surface of the coated film and enriched yourself there. This gives the coated film better sliding properties, which when pressed on Profile body is advantageous.
  • Lubricant on the paint layer of the coated film to apply.
  • This can be a thin one, for example Clear coat, for example from a UV-curing Polymer, such as acrylate, or a hot sprayed paraffin his.

Claims (5)

  1. Procédé pour fabriquer un film en vue de produire une couche de protection superficielle sur un corps profilé, selon lequel un film substrat imprégné d'une résine d'imprégnation thermodurcissable est pourvu d'une couche de vernis, étant précisé que
    a) comme résine d'imprégnation, on utilise une résine de condensation aqueuse qui contient, lors de l'application du revêtement, environ 50 % en poids de composants volatils, et le film imprégné contient encore 8-20 % en poids de composants volatils avant le vernissage,
    b) le vernis est un système aqueux composé d'un produit de polymérisation acrylique, d'un produit de polymérisation polyuréthanne ou d'un produit de copolymérisation polyester, à groupes OH, auquel on a ajouté un composant de réticulation qui réticule le liant du vernis, d'une part, et qui permet une liaison chimique avec la résine d'imprégnation du film substrat, d'autre part,
    c) avant d'être appliqué sur le corps profilé, le film est séché jusqu'à atteindre une humidité résiduelle de 2-20% en poids, de préférence de 4-10 % en poids.
  2. Procédé selon la revendication 1, caractérisé en ce que le vernis est un hydroxyacrylate avec un polyisocyanate aliphatique.
  3. Procédé selon les revendications 1 et 2, caractérisé en ce que le vernis contient un lubrifiant.
  4. Procédé selon les revendications 1 et 2, caractérisé en ce qu'un lubrifiant est appliqué sur la couche de vernis.
  5. Utilisation d'un film fabriqué selon les revendications 1 à 4, pour appliquer au moins unilatéralement un revêtement extérieur sur un corps profilé qui est produit par compression, avec une pression élevée et une amenée de chaleur, à partir d'un mélange de copeaux ou d'éléments similaires et d'une résine synthétique thermodurcissable.
