Definitions

  • tapes based on continuous commingled PET fibres and glass fibres used in the prior art for reinforcing profiles could be replaced by tapes composed of a thermoplastic polymer and long chopped glass fibres positioned in an isotropic manner.
  • the content of the fibres is between 20 and 80 % by weight, preferably between 25 and 60 % by weight, in particular between 30 and 50 % by weight of the daughter tape.
  • step (a) of the process after dispersion of the first thermoplastic polymer in powder form over the fibres, an AC electric field is applied. This operation has the effect of advantageously distributing the powder in the fibres.
  • the heating is preferably carried out less than 1 m before the inlet, preferably of the die, very preferably less than 0.5 m before the inlet.
  • one preferred variant of the process therefore also makes provision, in step (a) or in step (b), for the end-to-end joining of two tapes, which is carried out over a length of at least 10 cm along a punched cut-out of triangular and parallel shape in two tapes having a height of at least 1 cm and a base of at least 5 mm, followed by removal of the parts cut out upstream of the tape leaving the reel to be replaced and downstream of the tape coming from the new reel, an application of adhesive to at least one of the edges of the tape and flat interlocking of the two ends of the two tapes. It is preferred, after having removed the parts cut out upstream and downstream of each tape, to weld together the interlocked ends using a laser.
  • Another aspect of the present invention therefore relates to a reinforced profile as described above in relation to the process.
  • the invention proposes a reinforced profile comprising a tape that serves as reinforcement, said tape containing a first thermoplastic polymer and long chopped fibres, and also a second thermoplastic polymer applied in the melt phase to at least one face of said tape.
  • the features and preferences given previously for the process according to the invention apply to the reinforced profile according to the invention.
  • another aspect of the present invention relates also to the use of the profile according to the invention or of the reinforced profile obtained by the process described above, for the manufacture of shutters, doors, gates, window frames, coverings for walls and ceilings (panelling, boards), cable conduits and skirting boards.

Abstract

L'invention porte sur un procédé pour fabriquer un profil renforcé (1), lequel procédé comprend (a) la fabrication d'au moins une bande fille contenant un premier polymère thermoplastique et de longues fibres hachées par dispersion du premier polymère thermoplastique sous forme de poudre sur les longues fibres hachées positionnées d'une manière isotrope ; l'application d'un champ électrique alternatif et d'un chauffage sous pression ; (b) facultativement, la fabrication d'une bande mère (3) par superposition et soudage d'au moins deux bandes filles obtenues lors de l'étape (a) ; et (c) la fabrication d'un profil renforcé à l'aide d'une bande fille obtenue dans l'étape (a) ou d'une bande mère (3) obtenue dans l'étape (b) par extrusion d'un deuxième polymère thermoplastique fondu sur au moins une face de la bande fille et sur au moins une face de la bande mère (3). L'invention porte également sur un profil renforcé (1) obtenu et sur l'utilisation de celui-ci.
