Definitions

  • the subject of the present invention is a method and a device for continuous coating of at least one metal strip with a fluid film and low thickness of crosslinkable polymer free of solvent or non-diluent reagent.
  • thermosetting polymers such as thermosetting polymers, or by physical means, such as, for example, photopolymerizable polymers.
  • thermosetting organic coatings which are applied continuously to metallic substrates.
  • these are complex formulations which combine in a solvent or aqueous medium a system of organic binders functional prepolymers, a crosslinking system and additives such as pigments or fillers, various formulation adjuvants.
  • organic coatings such as for example liquid paints or varnishes are most often made by coating with roll of these liquid coatings in the state of solution or dispersion in the medium solvent or aqueous.
  • the liquid coating is deposited on a metal strip by pre-dosing the solution or dispersion through a two or three roller system and by transferring part or the all of this liquid coating thus predosed on an applicator roller in contact with the surface of the metal strip to be coated.
  • the transfer is carried out either by friction of the applicator roller and of the metal strip, the running of the two surfaces in contact taking place in the opposite direction or either by contact in the same direction.
  • One of the techniques used for the application of such coatings consists in applying the organic coating in the form of a powder.
  • the liquid polymer is poured at the air gap of the cylinders, then flows between said cylinders and is deposited on the metal strip.
  • Coating extrusion of a thin organic coating is practiced commonly especially with thermoplastic polymers on flexible surfaces, such as paper, plastic films, textiles, or even thin metal substrates such as packaging materials.
  • the application of the molten coating is carried out by means of a rigid flat die or a nozzle positioned in direct contact with the substrate.
  • the pressure exerted by the die on the substrate comes from the viscosity of the melt.
  • the possibilities for correcting faults in flatness of the substrate by plating it on the support cylinder are very limited.
  • This coating extrusion technique requires perfect parallelism between the edges of the die and the substrate and this substrate must be either perfectly flat, or deformable to allow the formation of a thin thick deposit uniform.
  • the thickness of deposited material is controlled by the play and the pressure between the die and the substrate, which imposes a perfect parallelism of these two elements when we want to realize very fine applications thickness.
  • the technique of extrusion lamination of a uniform layer of fluid coating on a substrate uses the drawing under a die of a fluid sheet the outlet of a flat die, this sheet then being plated on the substrate to using for example a cold roller, a rotary bar or even by a air gap or an electrostatic field.
  • the thickness of the fluid layer is controlled by the material flow in the die section and by the substrate speed.
  • the tablecloth would then separate into two parts in its thickness, one part being applied to the substrate and the rest remaining applied to the roller. This separation of the sheet therefore implies that the transfer is not total and the coating obtained on the substrate does not have a satisfactory surface appearance, nor a uniform thickness.
  • the plating pressure must however be low enough to avoid the formation of a calendering bead and, therefore, this mode of transfer does not compensate for any variations in thickness and flatness defects in the case of a rigid substrate.
  • This coating application technique with the formation of a free strand at the outlet of the extrusion die avoids coupling problems between the die and the rigid substrate, but it induces application instabilities if the length of the free strand fluctuates and it is difficult to implement with thermosetting systems with viscosity lower than 2000 Pa.s in because of the difficulties in achieving regular stretching and good plating.
  • micro air bubbles can be interposed between the coating and the substrate which affects the application homogeneous and with the surface appearance of this coating.
  • the polymer coating after crosslinking, the polymer coating must be hard enough while being deformable to allow the shaping of sheets thus coated without causing degradation or detachment of the coating.
  • the rise in molecular weight of the precursors has a very unfavorable effect on the viscosity of a polymer free of solvent or diluent non-reactive which does not favor the transfer and application of the web on the metal strip.
  • the gripping cylinder according to EP-A-1 001 848 is surface tough.
