Definitions

  • the present invention relates to a base paper for decorative coating systems, in particular laminates, decorative films and prepregs.
  • Laminates are laminates that are created by pressing several impregnated, stacked papers and that generally have a melamine or polyester resin surface. This can consist of one or more layers and be anchored on different documents.
  • the classic laminate consists only of paper and resin, whereby the thickness-determining base consists of phenol-impregnated kraft paper.
  • the thickness-determining base consists of phenol-impregnated kraft paper.
  • wood materials for example, hardboard and chipboard as well as plywood are used.
  • Paper laminates generally consist of melamine-coated, transparent overlay paper, melamine-coated, colored and / or printed decorative paper, melamine-coated, opaque barrier paper and phenol-coated kraft paper.
  • Combined laminates usually consist of overlay paper, decorative paper, barrier paper or kraft paper and hardboard or chipboard.
  • Barrier papers are used as barrier layers between the phenolic paper and the decorative top layer to prevent the brown core layer from showing through and the penetration of phenolic resin into the decorative layer. They are made from highly bleached sulphate or sulphite pulps, which in addition to good wet strength and absorbency also require very good opacity.
  • the opacity that is so important for decor papers is achieved through high filler proportions.
  • White pigments such as zinc sulfide and titanium dioxide are suitable as fillers.
  • Other fillers such as calcium carbonate can also be used.
  • Zinc sulfide gives the paper excellent lightfastness (lightfastness). In addition to its relatively poor retention in the paper, there is also the risk of decomposition with elimination of hydrogen sulfide at the usual acidic pH ratios in the paper stock.
  • the rutile type of the various titanium dioxide pigments is particularly suitable.
  • the disadvantage is its high price. With TiO2 contents of up to 45% by weight in the decorative paper, it is therefore particularly important to ensure maximum retention of the pigment.
  • retention aids are added to the paper pulp.
  • retention agents include, for example, polyacrylamide (Khim. Pererabotka Drev. Ref. Inform. No. 12: 9-10, 1967) and polycarboxylic acids.
  • the known papers for laminated materials can still be improved with regard to the requirements placed on them. This also applies to the degree of whiteness, opacity and lightfastness.
  • the object of the present invention is to provide a base paper for decorative coating systems which has excellent properties, in particular with regard to opacity and light resistance.
  • corative coating systems is understood to mean both laminated materials such as decorative papers and barrier papers, and also decorative films and prepregs.
  • a base paper which is formed from a paper pulp which, in addition to at least one filler and a wet-strengthening cationic resin, contains anionic inorganic particles.
  • the anionic inorganic particles can in particular be selected from the group of colloidal silica, colloidal aluminum-modified silica or colloidal sodium- or aluminum-modified silicate.
  • the amount of anionic inorganic particles in the paper pulp can be up to 0.5% by weight.
  • the quantity range from 0.01 to 0.25% by weight is particularly preferred.
  • the quantities given relate to the pulp fiber content.
  • Suitable fillers are, for example, titanium dioxide, zinc sulfide, calcium carbonate, kaolin (china clay), talc or mixtures thereof.
  • a rutile titanium dioxide surface-treated with Al2O3 is used.
  • the amount of titanium dioxide in the paper pulp is between 1 to 55% by weight, but in particular 25 to 45% by weight.
  • Melamine-formaldehyde resins, polyamine or polyamide derivatives can be used as wet strength agents in amounts of 0.3 to 2% by weight.
  • the pulp may also contain other substances such as organic and inorganic colored pigments and dyes, optical brighteners and dispersants.
  • the base papers according to the invention are produced in a known manner using a paper machine in a grammage range from 50 to 200 g / m2.
  • the various components can be added to the pulp suspension in a different order and at different locations known to the paper manufacturer.
  • the anionic inorganic particles are fed to the so-called thin material before the headbox.
  • the retention was determined according to the "Britt" dynamic drainage year method (DDJ method) developed by Paper Research Materials, Inc. The test was carried out on untreated papers.
  • the laminate samples (4.5 x 10 cm) were exposed to radiation with a 1: 1 change from light to dark with the aid of a xenon high-pressure lamp (150,000 lux) for 96 hours.
  • a xenon high-pressure lamp (150,000 lux) for 96 hours.
  • the brightness L according to DIN 6174 was measured before and after the xenon text on the laminate samples. The larger the numerical value L, the higher the brightness.
  • the brightness was measured using the Elephro 2000 color measuring device (Data Color).
