Definitions

  • the present invention relates to a method and a device for continuously coating, over a wide thickness range, at least one substrate with a film of an organic and / or inorganic formulation in the state of solution or dispersion and whose viscosity is between 0.001 and 100 Pa.s.
  • This type of process is especially used to apply paints in the form of solutions or dispersions in an organic solvent on moving substrates, for example on metal strips.
  • a roll coating technique which consists in introducing paint, by gravity, into the air gap of a metering roller and a takeup roller.
  • a paint film of controlled thickness is first formed on an applicator roll in contact with the takeup roll on one side, and on the other side with the moving web, and then the whole or part of the coating.
  • the applicator roll is a roll whose surface is deformable.
  • Deformable surface rollers are generally formed of a metal core coated with an elastomer layer.
  • the friction of the metal strip against the coating of the applicator roll eventually generates a notch in the periphery of the roll of the same width as the width of the strip.
  • the operator is therefore forced to program the passage of cone strips of decreasing widths so as to pass the wider strips before the narrower strips;
  • the wear of the coating of the applicator roll is too marked or when one reaches the end of the cone and one starts doing again If you want to scroll through large width strips, it is necessary to change the applicator roll to either correct it or refill it.
  • the wear of the coating of the applicator roll generates particles of this coating which may cause coating defects by polluting the coating film.
  • the direct transfer mode When the device is used in the direct transfer mode, ie when the applicator roll is rotated in the same direction as the running direction of the band, the friction between the applicator roll and the band is small. . It is then possible to deposit films with a very fluid formulation whose viscosity is less than 0.01 Pa.s, or films of very thin thickness, without observing excessive wear on the surface of the applicator roll.
  • the direct transfer mode generates defects in the surface appearance of the coating deposited on the strip that is called stringing or lineage, defects all the more marked that the application is at high speed or thin .
  • the coatings when using the device in reverse transfer mode (reverse in French), the coatings have a beautiful surface appearance.
  • the applicator roll is rotated in the opposite direction to the running direction of the band, the friction between the applicator roll and the band is greater than in the direct transfer mode. It follows a significant wear of the coating of the applicator cylinder which will be more marked than the formulation is low viscosity and / or that the applied film is thin. To oppose the very high friction forces, it is often necessary to increase the motor power of the applicator roll. However, even by increasing the power of motorization, the application of coatings very thin or very low viscosity formulations is not always possible.
  • the document FR 2,767,074 discloses a method of continuously coating a metal strip with a crosslinkable polymer fluid film, wherein a web of the polymer is formed on a hard surface gripper cylinder, and the web is transferred to a surface applicator roll dimensionally stable.
  • the document WO 00/35593 also discloses a method of continuously coating a metal strip with a crosslinkable polymer fluid film, wherein a polymer web is formed not on a takeup cylinder, but directly on an applicator roll.
  • the invention aims to implement an identical coating process for continuously coating a substrate with a film as well as conventional paints which may have a viscosity of between 0.01 and 100 Pa.s. at room temperature, only surface treatment solutions, such as aqueous chromate solutions, whose viscosity is of the order of 0.001 to 0.01 Pa.s.
  • the formulations according to the invention have a viscosity of between 0.001 and 100 Pa.s at ambient temperature.
  • Viscosity formulations of less than 0.001 Pa.s at room temperature could be used, ie formulations in which the solvent or the dispersant is a volatile organic solvent, such as, for example, ether.
  • the solvent or the dispersant is a volatile organic solvent, such as, for example, ether.
  • these would not be of great industrial interest because of the volatile nature of the solvent which would require a complete rollover of the coating plant, as well as severe safety instructions of the operating personnel.
  • the use of this type of solvent is disadvised.
  • formulation is intended to mean a formulation either based on at least one polymer or based on at least one inorganic compound, and the solvent or dispersant of which is either organic or aqueous.
  • formulations based on at least one polymer in the form of a solution or dispersion in water or in an organic solvent means paints, varnishes or thin organic coatings (ROM).
  • formulations based on at least one inorganic compound in the form of a solution or dispersion in water or in an organic solvent means solutions for treating metallic surfaces, such as, for example, chromating.
  • Formulations in the form of solutions or dispersions in water or in an organic solvent may also contain, in the usual manner, fillers, pigments, catalysts, plasticizers, stabilizers or any other known additive.
  • the invention applies not only to metal substrates, such as steel, aluminum or an aluminum alloy, but also to glass, plastic, plywood, or any other suitable material.
