Definitions

  • the invention relates to a continuous process for surface coating a of metal substrates having a generally planar surface, on a coil-coating line for providing a durable and corrosion protecting coating on the metal surface.
  • paint- and lacquer materials are applied in two layers on the metal substrate with generally planar surface. These layers are applied as wet paint layers, which in dried state will have a certain degree of thermoplasticity.
  • the first layer is a chlorine-free primer coat, such as e.g. an acrylic, epoxy or polyester coat.
  • a chlorine-free, plastisol of an acrylic resin or of a polyester is applied as a paint layer.
  • Said such wet paint layer is dried after application and has in the dried condition a certain degree of thermoplasticity.
  • the paints are applied according to conventional techniques, such as roller coating, spray coating, curtain coating, etc.
  • the drying is also performed by conventional methods, such as IR-tubes induction or convection heating.
  • a chlorine-free plastic sheet or foil is applied directly upon the hot paint surface.
  • the plastic sheets applied directly upon the hot paint surface by lamination, e.g. using a pressure roller, are made of various suitable pore-free, and chlorine-free foil materials, such as sheets of fluorocarbon polymers, e.g. PVF, PVF 2 , of acrylic resins, of polyesters or of polyurethanes.
  • the plastic sheet and the second coat material together with the primer coat build up a barrier which provides a very good corrosion protection to the metal substrate and the total thickness of the primer and the second coat should be from ' 40 to 300 microns.
  • a surface coating with extraordinary hardness and wear resistance is obtained which provides an extraordinary corrosion protection to the underlying substrate material.
  • the sheet metal is preferably pretreated chemically by usual methods such as pickling, phosphatizing, chromating etc.
  • the layers of paint- and lacquer material consist of one primer layer and a second paint layer which can be pigmented or unpigmented.
  • the temperature of the metal sheet is from 150 up to 300 ⁇ C.
  • First layer An epoxy primer ("KE 215-1003 Coilon primer” from Becker Industrifarg AB, Marsta, Sweden) is applied by reverse roller coat to a thickness of 6-8 microns dry film, drying/curing at 225°C PMT (peak metal temperature) and cooled.
  • Second layer On the previous layer an acrylic plastisol (68815-12 Coilon Plastisol from Becker Industrifarg AB, Marsta, Sweden) is applied to a thickness of 80 microns dry film. By reverse roller coat, drying/curing at 240°C PMT.
  • Third layer Directly upon the previous hot layer, a plastic sheet of acrylic resin (Korad 73002 from Polymer Extruded Products” Inc. newark N.J. USA) and a thickness of 50 microns is applied.
  • a coating is obtained which provides excellent corrosion protection, high hardness and excellent wear resistance.
  • Alu-zink coated steel is used.
  • an epoxy primer (KE216-1003 from Becker Industrifarg AB, Marsta, Sweden), instead of KE215-1003.
  • a coating is obtained which provides excellent corrosion protection, high hardness and excellent wear resistance.
  • a coating is obtained which provides excellent corrosion protection, high hardness and excellent wear resistance.

Abstract

Procédé de revêtement de surface, pour des surfaces planes, selon lequel du vernis et de la peinture dépourvus de chlore sont appliqués sur la surface plane sous forme de peinture humide appliquée en deux couches, chaque couche étant séparément séchée avant l'application de la prochaine couche, l'épaisseur de la couche plane totale étant comprise entre 40 et 300 microns, une feuille de plastique étant ensuite appliquée par laminage directement au-dessus de la surface de la couche de peinture chaude.
