Definitions

  • the invention relates to a decorative base paper and under Using the same produced decorative films or decorative laminates.
  • Decorative coating materials are preferably for Surface coating in furniture manufacturing and in the Interior fitting used.
  • Under decorative film is understood a resin impregnated or resin impregnated and surface treated, printed or unprinted Paper web.
  • Decorative foils are provided with a carrier plate glued or glued.
  • Laminates High Pressure Laminates
  • the structure of these laminates consists in general from a highest surface resistance generating transparent overlay sheet (overlay), a resin-impregnated decorative paper and a phenolbehaticianm Kraft paper.
  • Overlay transparent overlay sheet
  • resin-impregnated decorative paper a resin-impregnated decorative paper
  • phenolbehaticianm Kraft paper a resin-impregnated decorative paper
  • Woodboard and chipboard as well as plywood used.
  • the decorative paper impregnated with synthetic resin is pressed directly with a base, for example a chipboard, using a low pressure.
  • the decorative paper used in the above-mentioned coating materials is used white or colored with or without additional imprint.
  • Decorative base papers generally consist of highly white Sulphate pulps, mainly of hardwood pulp, to 45% pigments and fillers and wet strength agents, Retention aids and fixatives.
  • decorative base paper differ from usual papers by the very much higher filler content and the absence of a Paper with standard sizing or surface sizing with the known sizing agents such as alkylketene dimers.
  • Opacity is one of the most important properties of Decorative base. This characterizes the opacity opposite the pad. To secure sufficient Opacity become the pulp fillers in high quantities added. To ensure good retention of the fillers in the sheet to reach the paper pulp are different Retention agent added. On the other hand, with rising Pigment content and filler content deteriorate the Strength and the impregnation behavior of the paper.
  • the strength of the decorative base paper especially the Dry strength, but is for further processing, during transport through the printing press or at Rewinding processes in the paper machine important.
  • US 4 505 775 relates to the production of cationic cellulose and its use in the Papermaking.
  • the cationic cellulose becomes the retention of dyes and fillers, in particular organic additives, in papermaking improved.
  • the object of the invention is therefore, a decorative paper with high mechanical strength, high opacity and sufficient absorbency (impregnation ability) provide.
  • a decorative base paper the from a pulp fiber and filler containing Paper pulp is formed, the pulp a Pulp mixture of a non-modified and a contains cationically modified pulp and the cationically modified pulp is an effective cationic charge of 20 to 300 mmol / kg and in the pulp mixture in an amount of at least 5% by weight is included.
  • Cationically modified pulps are for example from THE PAPER, Issue 12 (1980) p.575-579. their Use in decorative base papers and the resulting Strength increase can not be done in the prior art remove. Particularly advantageous is a proportion of 10 to 50 wt.%, In particular 10 to 20 wt.% Of the cationic modified pulp in the pulp mixture proven.
  • the in the pulp cationically modified Pulp has an effective cationic charge of 20 to 300 mmol / kg pulp, determined by the internal method No. 4 of the TU Darmstadt. Preference is given to pulp fibers with a charge density of 30 to 200 mmol / kg, in particular 30 to 100 mmol / kg. Under the term effective cationic charge "is a charge density too understand that with the charge density of not cationized pulp was calculated.

  • the unmodified pulp and the cationic modified pulps are preferably short fiber pulps with a mean fiber length of 0.5 to 0.7 mm, but also long-fiber pulps or blends Both types of pulp can be used.
  • Short fiber pulps are, for example, hardwood pulps of aspen, beech or eucalyptus, of which last is particularly preferred.
  • the pulp has preferably a freeness of 30 to 45 ° SR.
  • Suitable fillers are, for example, titanium dioxide, in particular of the rutile type, zinc sulfide, calcium carbonate, kaolin, talc or mixtures thereof. Particularly preferred is a rutile type titanium dioxide surface treated with Al 2 O 3 .
  • the proportion of the filler in the decorative base paper can be up to 55% by weight, in particular 20 to 45% by weight.
  • a wet strength agent can melamine / formaldehyde resins, Polyamine derivatives or polyamide derivatives in amounts of 0.3 up to 2% by weight, based on the weight of the pulp, be used.
  • the decorative paper may contain other substances such as organic and inorganic colored pigments, dyes, optical brighteners and dispersants used in the preparation of the decorative base paper added to the paper suspension become.
  • the decorative base papers according to the invention are produced in a known manner in a paper machine in a grammage range of 50 to 200 g / m 2 .
  • filler and wet strength agent are added and mixed well with the pulp mixture.
  • the thick stock thus obtained is diluted to a stock consistency of about 1% and, if necessary, further auxiliaries such as retention aids, defoamers, aluminum sulfate and, optionally, wet strength agent admixed.
  • This thin material is fed to the wire section via the headbox of the paper machine. It is formed a nonwoven fabric and obtained after dewatering the decorative base paper, which is then dried.
  • Resin dispersions impregnated or impregnated are common synthetic resin dispersions for example, those based on polyacrylic or Polyacrylmethyl esters, polyvinyl acetate, polyvinyl chloride or synthetic resin solutions based on phenol / formaldehyde, Urea / formaldehyde or melamine / formaldehyde precondensates or their compatible mixtures.
  • the impregnation can also be done in the size press of the Paper machine done.
  • the decorative paper can be so be impregnated, that the paper is not complete is impregnated by.
  • Such decorative papers are also referred to as prepregs.
  • the proportion of in the Decorative base paper by impregnation of incorporated resin is in this case 25 to 30 wt.%, Based on the Weight of the paper.
