Definitions

  • the invention relates to a method for coating substrates with one or more layers containing hydroxyl-containing polymers such as polyvinyl alcohol or Polyvinybutyrale by curtain coating without the use of surfactants or surfactants.
  • hydroxyl-containing polymers such as polyvinyl alcohol or Polyvinybutyrale
  • substrates such as paper or cardboard
  • the coating of substrates such as paper or cardboard is being carried out industrially for the production of photographic papers, ink-jet printing papers, graphic papers or food packaging.
  • Coatings for papers must be applied in the paper industry for large areas of constant thickness at high paper web speeds.
  • contactless methods in which the application tool does not touch the substrate are suitable for this purpose.
  • Contactless methods are, for example, the slot die coating process, spray coating or curtain coating.
  • the curtain coating process is used in particular at high paper web speeds and delivers uniform coating thicknesses in high quality.
  • Curtain coating processes are, for example, in US2003 / 0188839 A1 .
  • the quality of the curtain coating process depends to a great extent on the consistency of the curtain of the liquid. In this case, only slight variations in the thickness of the curtain or the density of the liquid may occur, which would otherwise cause errors in the coating. Furthermore, the curtain must not tear off, which places high demands on the constancy of the viscosity of the liquids used for coating.
  • the dynamic surface tension of the coating liquid used is important. If the surface tension is too high, either no curtain forms at all, or the curtain is unstable and breaks up until droplets form.
  • the dynamic surface tension of the coating liquids used must be carefully adjusted. This is usually done by adding surface-active substances, so-called.
  • Surfactants such as non-ionic (eg, glycols, polyglycols or alkylene glycols) or ionic surfactants.
  • Curtain-coating processes with surfactants are, for example, in WO 03/0160645 or US 2003/0188839 or US 2006/0009941 disclosed.

  • the organic solvents used in the coating liquids also significantly improve the drying of the coatings.

  • Nonionic surfactants are, for example, glycols, polyglycols or alkylene glycols, for example the Surfynol or Envirogem series, ethoxylated and unethoxylated 2,4,7,9-tetramethyl-5-decyl-4,7-diols, oxiranes, 1,4- Dimethyl-1,4-bis (2-methylpropyl) -2-butyl-1,4-diethyl ether, 1,3-pentadiol, trimethylpentadiol, glycerol, Triton X100, Terstol.
  • ionic surfactants are sodium salts of polyacrylic acids, quaternary alkylammonium salts (eg hexadecatrimethylammonium chloride), betaines or metal salts of fatty acids, aliphatic esters of dicarboxylic acids or lauryl sulfates.
  • the coating liquids used have a dynamic surface tension (Mach angle) of max. 50 mN / m, in particular less than 40 mN / m.
  • the Mach-Angle will be like in Swiss PMS, "Measurement of the Dynamic Surface Tension with the Mach Angle Method", Polytype Technical Report 2006 or in " Waves in a liquid curtain ", Lin, SP and Roberts, G; Journal of Fluid Mechanics, vol. 112, p.443-458 described, measured.
