Definitions

  • the invention relates to a method for reducing the water vapor permeability of paper, cardboard or the like, in which the paper is coated with an application medium.
  • the collective term paper also includes cardboard, cardboard and similar nonwovens.
  • the object of the invention is to produce a water vapor-tight paper which is fully recyclable, consists of toxicologically and biologically completely harmless components and is in particular free of chlorine.
  • the application medium is formed from a free resin dispersion which contains additives, including surfactants or waxes, and preferably further additives, to improve the film-forming properties.
  • the raw material for the production of resin glue is divided into three different basic types after they have been extracted, these are: root resin, balsam resin and tall resin.
  • the main constituent of the resins of interest in this context are resin acids, the most important of which are: Abietic acid Levopimaric acid Palustric acid Dehydroabietic acid Dihydroabietic acid Tetrahydroabietic acid Pimaric acid Isopimaric acid
  • the raw resins are usually "reinforced", i.e. 8-13% maleic anhydride or fumaric acid is added to the resin at about 200 ° C.
  • the resins are then dispersed in water, generally using casein as a protective colloid to stabilize the dispersion.
  • casein as a protective colloid
  • surfactants or waxes are used as additives.
  • Henkel's dehydol types based on fatty alcohols and fatty alcohol polyglycol ethers can be used as surfactants.
  • Paraffin wax dispersions are used as waxes.
  • a particular advantage of the method according to the invention is that the application can be carried out on any coating device customary in paper production.
  • the stroke is possible with an air knife or blade as well as a doctor blade with normal drying.
  • the application medium is water-based and therefore free of organic solvents and chlorine compounds. Furthermore, it is inexpensive to manufacture.
  • Free resin glue dispersions are known per se as sizing agents for papers, but generally only as bulk sizing agents, i.e. they are added in the paper machine before sheet formation. However, it was previously believed in the specialist world that such glues were not suitable as coating compositions for application in a coating system, since the film-forming properties were too poor.
  • EP-A 37 055 and DD-A 211 819 also describe the use of resin glues for gluing paper. What has been said about AT-B 372 432 applies here analogously.
  • GB-A 1 604 847 further relates to the surface treatment of paper with foams which contain resin. The purpose here is also the hydrophobization. Various additives are said to control foam formation. None can be gained for the invention from this publication either.
  • the film formation is achieved at 50 ° - 120 ° C and at the same time the water is evaporated from the emulsion. Furthermore, the strength values in the paper treated by the process according to the invention are improved by approximately 15-20%. Gluing is possible without any problems. It is also possible to dissolve the coated paper without difficulty in the pulper at fabric densities of about 3 to 15%.
  • the base paper is pigmented before coating. In this way, the required order quantity for the barrier effect can be drastically reduced. In this way, the paper can be made white and at the same time waterproof.
  • Alkylphenol polyethylene glycol ethers can be used as additives, e.g. Lutensol AP from BASF. It is particularly favorable if amines are provided as further additives, e.g. Triethanolamine or diethylethanolamine.
  • Ammonia can also be used as an additive. If ammonia is added as a 25% solution as an additive, a highly viscous, spreadable, clear solution is obtained with NH 3 additions of 1% - 10% and preferably 3% - 5%. The mixture is made by stirring the ammonia water into the resin glue dispersion until a clear solution is obtained.
  • the use of ammonia achieves a water vapor tightness that at least corresponds to that that can be achieved with other additives. However, such a method is always associated with ammonia emission, which makes it necessary to scrub the exhaust air.
  • fatty alcohols e.g. Henkel's dehypon or dehydol
  • fatty alcohol ethoxylates e.g. Peratom 123 from Henkel or fatty alcohol polyglycol ether with fatty acids, e.g. Dehydol HD-FC-6 from Henkel
  • fatty acids e.g. Dehydol HD-FC-6 from Henkel
  • the brittleness can be significantly reduced and the strength can also be increased somewhat.
  • a filler is added to the application medium.
  • Platelet-shaped pigment substances such as e.g. Talc, because this structure extremely extends the diffusion path of water vapor. In principle, however, all pigments can be used for the purpose of saving chemicals. You can use fillers from the group of calcium carbonate, aluminum hydroxide, aluminum silicate and titanium oxide.
  • the solids content of the application medium is set to 20 to 70%, the viscosity being between 30 and 800 mPas, preferably between 50 and 300 mPas. In this way it is possible to work with all common application units without any problems.
  • This primer can basically be applied with the same application medium as the actual coat, but a medium with an increased filler content can be used. In this way, the amount of resin required can be minimized.
  • a paper surface temperature of 20 ° to 160 ° C., preferably 50 ° to 130 ° C., is required. The temperature depends on the softening point of the resin glue that is used. With this double line, an extreme water vapor density can be achieved, which is less than 20 g / m2d (WDD 90% ). Furthermore, such a double stroke is particularly useful if the layer thicknesses that are not as great as required in a single application. can be applied.
  • the primer contains polyvinyl alcohol and in particular consists of a mixture of polyvinyl alcohol and pigments. Furthermore, this primer is to be subjected to a thermal treatment with temperatures between 120 ° C and 170 ° C, preferably between 140 ° C and 160 ° C. It has been found that a coating with a PVA-containing mass has a very low water vapor permeability due to the thermal treatment. Polyvinyl alcohol is also completely free of halogens and completely toxicologically and ecologically harmless. In particular, no organic solvents are required. In addition to the polyvinyl alcohol, fillers such as calcium carbonate, mica, kaolin, aluminum hydroxide, Aluminum silicate, talc, starch, or titanium oxide can be provided. Furthermore, an ethylene-acrylic acid copolymer can also be included in the coating, as a result of which particularly good resistance to water and better water vapor tightness are achieved.
  • a top coat is additionally applied. It is advantageous if the top coat contains polyvinyl alcohol and that this top coat is subjected to a thermal treatment at temperatures between 120 ° C and 170 ° C, preferably between 140 ° C and 160 ° C.
  • the advantages described above of coating compositions containing polyvinyl alcohol also apply to the top coat. Since polyvinyl alcohol has a particularly good water vapor impermeability in the range of small to medium atmospheric humidity, whereas the line with a free resin glue dispersion can be used particularly advantageously in the range of high moisture levels, the double-coated paper will always be used so that the layer with the free resin glue dispersion faces the moist side . In the case of a pre-coat with PVA, which is covered by a layer that contains a free resin dispersion, the coated side of the paper is oriented towards moisture. In contrast, with paper that has a PVA top layer, the coating will always be oriented towards the dry side.
  • the water vapor diffusion barrier consists of a resin-based base coat (resin glue, surfactant, polyvinyl acetate, takum) and a PVA-based top coat with pigments.
  • resin-based base coat resin glue, surfactant, polyvinyl acetate, takum
  • PVA-based top coat with pigments.
  • the wetting and adhesion of the PVA top coat on the resin coat can be improved by a corona treatment. This eliminates the need for surfactants in the PVA top coat.
  • the invention relates to a paper with increased water vapor tightness, which is coated with an application medium.
  • Such paper is characterized in that the application medium is formed from a free resin dispersion, which additives to improve the film-forming properties, including Contains surfactants or waxes, and preferably further additives.
  • a kraft sack paper of 70 g / m2 machine-smooth is used as base paper for all examples.
  • this paper is examined uncoated.
  • this paper is conventionally polyethylene-laminated.
  • the water vapor permeability (like WDD) in g / m2 and day is determined for all examples under two different conditions.
  • the coating is done as a double coat with 12 g / m2 application amount for the first and 7 g / m2 for the second coat.
  • the coating is done as a double coat with 12 g / m2 application amount for the first and 7 g / m2 for the second coat.
  • the coating of example 2 has the advantage over that of example 1 that it has greater elasticity and thus improved kink resistance, the internal strength of the coating being much higher.
  • PVA coatings are examined.
  • an uncoated paper is first juxtaposed with paper that is coated with a line of polyvinyl alcohol and ethylene acrylic acid in a ratio of 70:30.
  • Coatings with the following composition are examined in the two right columns: 35% polyvinyl alcohol 65% talc
  • a coating according to Examples 1 and 2 is combined with a free resin glue dispersion together with a coating of Example 3 PVA, a synergy effect results from the fact that the free resin glue coat is particularly effective at high atmospheric humidities, whereas the PVA coat has its advantageous properties particularly shows lower and medium humidity levels.
  • the line with the free resin dispersion is on the wet side and the PVA is on the dry side of the paper.
  • the free resin glue dispersion the composition of which corresponds to that of example 2, is applied in a smaller amount.
  • Example 5 only a PVA coating consisting of 65% talc and 35% PVA Mowiol 6-98 is applied, which has been heat-treated at 140 ° C.
  • a free resin glue dispersion base coat according to example 4 is combined with a PVA top coat according to example 5.
  • a double coat with a free resin glue dispersion with an application quantity of 10 g / m2 is combined with a PVA coat, the PVA-coated side facing the dry climate.
