Definitions

  • the properties of the composite can be improved by using special polyvinyl butyral (PVB) based films to a large extent constant material properties of float glass by modifying the film interlayer.
  • PVB polyvinyl butyral
  • the sub-films may also contain mixtures of plasticizers of both different and the same composition.
  • different composition is meant both the nature of the plasticizers and their proportion in the mixture.
  • the total plasticizer content is 25 to 40% by weight, particularly preferably 30 to 35% by weight.
  • the proportion of polyalkylene glycol in a partial film is preferably more than 5% by weight, more preferably more than 10% by weight, in each case based on the total film formulation.
  • plasticizer in different functional layers, their different affinity for the respective plasticizer.
  • Partial films are combined prior to the actual glass laminate production, whereby the migration process of the plasticizer components begins. After adjusting the thermodynamic equilibrium of the plasticizer concentration, the film laminate having the desired properties is obtained.
  • the process of the invention is significantly easier to carry out than coextrusion of sub-films.

Abstract

La présente invention concerne un procédé de fabrication de feuils formant une couche intermédiaire pour vitrages feuilletés, lequel consiste à combiner des feuils partiels contenant un plastifiant pour constituer un feuil formant une couche intermédiaire avec migration de parties de plastifiant entre les feuils partiels. L'invention concerne également la production de vitrages feuilletés comportant ces feuils formant une couche intermédiaire.
