Definitions

  • the invention relates to a method for coating paper or cardboard for creation an aroma and vapor barrier.
  • vapor and aroma barriers are achieved through coatings that are a mixture of several, preferably three polymers, namely paraffin, carboxylated styrene butadiene as well as polyacrylate (EP-A 0 393 451).
  • the disadvantage of this coating is that the coating slip can contain a lot of wax to make it necessary Achieve vapor and aroma barrier. This extra material means higher costs, and above all problems with recycling and heat sealing.
  • DE-A 42 27 184 describes an impregnating agent for the production of papers penetration resistance to greases, oils and aqueous media.
  • surface sizing takes place, in particular by means of a size press in the paper machine.
  • penetration resistance achieved with this method is only slight and by no means a vapor barrier.
  • the invention Combination line with a specific primer and with another, suitable for creating a vapor barrier has all essential Advantages of the previous PE-coated papers or boxes and thus represents a full-fledged one Substitute for these.
  • coated papers or boxes depending on the respective certification of the used top coat component (s) and their layer thickness as ream wrapping paper Moisture protection, heat-sealable wrapping paper for the production of armored packaging for paper rolls, wrapping paper with moisture protection, packaging for food, Aroma protection packaging, packaging for liquid food, packaging for bulk goods, washing powder packaging, insulation papers for the construction industry, wallpaper papers etc. usable.
  • the components of the primer coating are in their Original state, i.e. dissolved in water prior to application and can so be applied. The polymerization then takes place after the application.
  • the application quantity of the primer is between 2.5 and 5 g / m 2 depending on the nature of the base paper.
  • a barrier effect according to DIN 53122 Klima D by the primer alone is not measurable (over 135 g / m 2 / 24h).
  • the primer according to the invention almost completely prevents the migration of polymer dispersions into the paper or cardboard. This results in improved networking and thus a denser film build-up, as well as a reduction in the required application quantity (layer thickness).
  • top coat in the coating slip suggests that the Spread of the top coat a copolymer modified with carnauba and paraffin wax of styrene and butadiene or an ethylene / methacrylic acid polymer dispersion or a contains carboxylated styrene-butadiene copolymer or a styrene-acrylate copolymer dispersion.
  • the top coat can be an additional coat with a coating of a styrene-acrylate copolymer dispersion contain.
  • a further development of the coating slip of the top coat suggests that it is in a liquid Solvent, especially water, is dissolved.
  • the components of the coating slip of the top line are in their original state, i.e. before the order especially in Dissolved water and are so applied.
  • top coat be a polyvinyl acetate is added.
  • the application of the primer and top coat by means of a doctor blade, engraving systems or modifications thereof.
  • the order the primer and top coat can thus be achieved using known coating techniques, which are suitable for achieving thin coating layers. Preferably be used machines with two coaters.
  • the paper or the cardboard is on both sides is coated.
  • the coatings can of course accordingly the respective requirements on the two sides may be different, with the most varied Combinations of the primers and top coats according to the invention are conceivable.
  • the paper or cardboard is surface-sized is. This compresses and supports the paper or cardboard surface hence the effect of the primer.
  • An embodiment of a paper or cardboard according to the invention is as follows described with reference to the drawing. This shows a in a purely schematic representation kind of cut through such paper or cardboard, which first with a primer and then with a top coat to create an aroma and vapor barrier has been coated.
  • paper or cardboard 1 is initially closed in a purely schematic manner detect. It can also be recycled paper, for example.
  • a primer 2 is applied to the paper or cardboard 1.
  • the chemical composition this primer 2 has been previously described. It is in the drawing recognizable that the primer 2 almost completely in the surface area of the paper or Cartons 1 penetrates.
  • the special selection of the individual components in this primer 2 guarantees saturation of the capillary fiber structure of the substrate after the polymerization and covers them with one amorphous network structure.
  • With a suitably coordinated rheology of the primer 2 subsequently applied top coat 3 the remaining in the primer 2 Openings for a good anchoring of this top coat 3, knocking away is effectively prevented. This ensures that the polymerization is optimal necessary aqueous components remain in the top coat mass long enough and an improved arrangement of the film-forming molecules arises.
  • a one-sided coating is provided.
  • both the front and the back of the paper or boxes 1 are each provided with a coating according to the invention.
