Definitions

  • the invention relates to prepregs, a process for their preparation and decorative coating materials obtainable therefrom.
  • Decorative coating materials are preferably used for surface coating in furniture production and interior design, especially for laminate flooring.
  • These decorative films are resin-impregnated and optionally subsequently surface-treated paper webs that are decorative printed or unprinted and in a no longer reactivated under pressure and heat condition.
  • thermosetting decorative films with impregnated core offline process
  • decorative films based on prepregs on-line process
  • Decorative films based on prepregs are already more or less deeply soaked within the paper machine, immediately after sheet formation and drying, with a resin mixture, depending on the basis weight of the base paper. After drying and smoothing, usually also within the paper machine, the paper or the film must be crosslinked and thus be gap-resistant, so that during the subsequent processing steps of the finish coating and lamination on corresponding carrier no fiber separation occurs within the decorative film.
  • the prepregs for further processing high coverage and surface quality, good printability in rotogravure, good paintability (high paint level), good flatness and bondability with chipboard and MDF boards (medium-density fiberboard) required.
  • the thermally crosslinkable impregnating resins commonly used for the preparation of prepregs are water-dilutable, formaldehyde-containing resin solutions based on urea, melamine or phenolic resins. Since their sole use leads to relatively brittle products, these resin solutions are generally used in combination with water-dilutable, thermally crosslinkable polymer dispersions based on acrylic acid, acrylic acid ester, styrene, butadiene, vinyl acetate or acrylonitrile.
  • the resin absorption can be between 5 and 35% by weight, with the proportion of resin solutions generally penetrating deeper into the base paper than the proportion of polymer dispersions.
  • the latter are more or less rich on the top and bottom of the paper and ensure good smoothability and thus printability and Oberfilumbleendimi and thus paintability (paint level) of the papers.
  • the resin solutions are intended to ensure the good gap strength and flatness of the prepreg by crosslinking the fiber-resin composite during further processing.
  • the penetration depth of polymer dispersions can be increased by various additives, for example by water-soluble polymers based on polyvinyl alcohols, gelatin, starches, cellulose derivatives, alginates and mixtures thereof (EP 0739 435 B1 ), Maleic acid copolymers (EP 0 223 922 A1 ) or a copolymer of (meth) acrylamide and (meth) acrylic acid ( DE 197 28 250 A1 and DE 197 584 79 A1 ).
  • the first at a heat treatment of the prepreg over a period of about 40 seconds at about 132 ° C according to DE 101 34 302 C1 largely crosslinked (degree of crosslinking of at most 85%), these disadvantages are avoided.
  • the resin solution used for this purpose, its production and possible uses, inter alia for the impregnation of papers for decorative applications, are in the DE 197 35 959 A1 described.
  • a disadvantage is that such until hot compression on the carrier material (eg chipboard) as the last further processing step completely unvemetztes prepreg according to DE 101 34 302 C2 until then has no better or even worse internal strengths than known formaldehyde-free or -contaminated prepregs.
  • the invention is therefore an object of the invention to provide teilvemetzten prepregs that largely avoid the disadvantages mentioned at the end of the paper machine and as far as possible by high surface quality, good printability and higher splitting strength than known formaldehyde-free or prepregs, good paintability (high paint level) , good flatness and bondability with conventional adhesives Characterized in the subsequent processing stages and thus are almost equivalent in properties off-line impregnated papers.
  • the prepreg according to the invention is obtainable by impregnating a base paper with a Impregnating combination containing a thermally curable, formaldehyde-free resin solutions and a thermally crosslinkable polymer dispersion.
  • the impregnated base paper is dried and smoothed. The smoothing is expediently carried out within the paper machine used to produce the prepreg.
  • the degree of crosslinking of the prepreg is at least 10% and at most 85%.
  • the impregnated base paper has a residual moisture of 2 to 3 wt .-%.
  • the degree of crosslinking is analogous to that in the DE 101 34 302 C1 test method described by punching an area of 100 cm 2 in a pre-impregnate, weighed and kept in water at a temperature of 60 ° C for 15 minutes, rinsed, dried in an oven at 130 ° C and weighed again. From the weight difference and the known order of the impregnating resin or the impregnating combination (eg 12 g / m 2 dry with a 60 g / m 2 pre-impregnate), the soluble fraction of the polymer or polymers can be determined. The degree of crosslinking in% is then 100 - soluble fraction in%.
  • the invention also provides a process for producing thermally partially crosslinked, formaldehyde-free prepregs within the paper machine and their use as decorative coating materials.
  • prepregs are understood to mean partially impregnated papers in the formaldehyde-free resin solutions in combination with polymer dispersions.
  • the proportion of the impregnating components is from 5 to 35% by weight, preferably from 10 to 30% by weight, based on the weight of the raw paper.
  • the residual moisture content of the prepreg is between 1.5 and 3% by weight. At residual moisture contents of more than 3.5% by weight, the prepreg can adhere to machine parts, for example to the calender rolls of the paper machine.
  • a resin for impregnating the base paper, a resin can be used which contains the aforementioned components B) and C), but not the component A).
  • Such resins are in the DE 197 35 959 A1 disclosed.
  • the inventive water-dilutable impregnating mixture from o.g. Formaldehyde-free resin solutions A) + B) + C) or B) + C) and commonly used polymer dispersions is applied to at least one side of the paper web, then dried to a residual moisture content of 2 to 3 wt .-% and then smoothed.
  • the impregnated base paper is thereby partially crosslinked, the degree of crosslinking depending on the mixing ratio of the impregnating combination between at least 10% and max. 85%
  • this partially crosslinked prepreg is sufficiently flexible. It is particularly advantageous for the quality of the prepreg if the residual moisture is already set in the paper machine ("on-line"). Under a paper machine is understood in accordance with the general use of the word, the plant for papermaking, starting from the screening of the pulp suspension to the rolling up of the base paper.
  • the mixing ratio between formaldehyde-free resin solution (I) and polymer dispersion (II) is (solid: solid), 45:55 to 30:70. Mixture ratios of 35:65 to 30:70 are particularly preferred, since prepregs which have been produced with impregnation combinations having these mixing ratios are particularly easy to print and are sufficiently flexible.
  • the concentration of the impregnating mixture according to the invention, which contains further additives if required, can be up to 50% by weight.
  • the impregnating combination according to the invention can be applied online to the paper web in an amount of between 5 and 35% by weight, preferably between 10 and 30% by weight, based on the basis weight of the base paper.
  • application devices all commonly used within the paper machine units can be used, preferably roller application devices, such as size press or film press.
  • prepregs according to the invention already have better properties than previously known formaldehyde-containing and formaldehyde-free prepregs with regard to printability and surface strength (Tesafestmaschine) immediately after the paper machine. At the same time they retain a high surface density (high paint level) and dimensional stability / flatness, the formaldehyde-free uncrosslinked prepregs according to DE 101 34 302 C1 , so impregnated with the above-mentioned formaldehyde-free resin solutions according to DE 197 35 959 A1 do not own after the paper machine. In the case of the last-mentioned prepreg, partial crosslinking takes place only at the end of the entire process chain of further processing, ie hot-pressing.
  • the prepreg according to the invention is thus significantly more universally applicable in the further processing steps and is not subject to any technological limitations with respect to various process parameters, such as speed, temperature and pressure.
  • the prepregs according to the invention can be prepared so that they have high flexibility, dimensional stability and good barrier properties against water and solvents and can be used in particular as a base material for high-quality specialty papers, such as printing and advertising media, decorative wall materials, abrasive papers, adhesive tapes or floor coverings.
  • the raw papers to be impregnated according to the invention are those which are described, inter alia, in the patents EP 0223 922 A1 .
  • EP 0870 872 A1 and DE 101 34 302 A1 are described.
  • the impregnation, drying and smoothing methods used in the documents cited and in the trade journal " Kliblatt für Textilfabrikation "No. 6 (2000), pp. 350 to 355 described in detail and known prior art.

  • the freeness was 30 ° SR (Schopper-Riegler).
  • the additives used were 25% titanium dioxide and 4% formaldehyde-free wet strength agent on dry pulp.
  • This raw paper without engine sizing and with a basis weight of 48 g / m 2 was impregnated on both sides in a laboratory size press with a formaldehyde-free resin solution of about 30% solids content of modified polyacrylic acid and a polyhydric alcohol (Acrodur 950 L Fa. BASF) and then at dried at different temperatures within about 18 seconds to a residual moisture content of about 2%.
  • the amount applied after drying was 10 g / m 2 .
  • Table 1 shows the degrees of crosslinking of the prepregs dried at different temperatures. This is followed by partial cross-linking of the prepregs up to about 30%, with drying conditions customary in the paper machine (up to 110 ° C., drying time about 300 seconds).
  • the base paper from Example 1 was impregnated by means of a laboratory size press with the impregnating mixture according to the invention from a formaldehyde-free resin solution (Acrodur 950 L) and a styrene-acrylate dispersion (Acronal 305 D from BASF) in a ratio of 35:65 (solid: solid) and dried at temperatures of about 110 ° C to a residual moisture content of about 2% within about 18 seconds.
