Definitions
- the invention relates to prepregs and from materials avai ⁇ che Dekorimlessnessgnate or decorative Be Schweizerungswerk-.
- Decorative coating materials so-called Dekorpa ⁇ piere or decorative films, are preferably chenbe Anlagenung for surface in furniture manufacture and interior fittings, in particular laminate floors, are used.
- de ⁇ korpapier / decorative film is meant resin impregnated or resin-impregnated and surface-treated, printed or unprinted papers.
- Decorative papers / decorative foils are glued or glued with a carrier plate.
- Laminates are ⁇ lamina te caused by compressing several impregnated, of stacked papers.
- the structure of these laminates generally consists of a highest surface resistance producing transparen ⁇ th overlay sheet (overlay), a resin-impregnated Dekorpa ⁇ pier and one or more phenolbehstoffen kraft papers.
- ⁇ th overlay sheet overlay
- Dekorpa ⁇ pier resin-impregnated Dekorpa ⁇ pier
- phenolbehstoffen kraft papers As a basis for example Hartfa ⁇ ser- and chipboard and plywood are used.
- the polymers prepared according to the short-cycle method laminates laminates (low pressure laminates), the resin-impregnated decorative paper ge ⁇ is compressed directly with a substrate, wherein ⁇ play, a chipboard, using low pressure.
- the decorative paper used in the above-mentioned coating materials is used white or colored with or without additional imprint.
- the so-called decorative base papers serving as starting materials must fulfill certain requirements. These include high opacity for better coverage of the substrate, uniform formation and grammage of the sheet for a uniform resin absorption, high light resistance, high purity and evenness of the color for good re ⁇ producibility of the pattern to be printed, high wet ⁇ strength for a smooth impregnation, corresponding absorbency to obtain the requis ⁇ chen resin saturation level, dry strength, which is important in Umroll processes in the paper machine and printing in the printing press. Furthermore, the Spaltfes ⁇ ACTION is of particular importance as it is a measure of how well the decorative base paper can be processed. So the glued on decorative paper / decorative film should not unravel at Bear ⁇ beitungsuzeen such as sawing or drilling.
- the decorative base papers are printed.
- the rotogravure so-called ⁇ is used, in which the print image by means of several gravure rollers on the pier Pa ⁇ is transmitted.
- the individual pressure points are to be completely and as intensively as possible transferred to the Textiloberflä ⁇ che.
- Dekortiefdruck only a small portion of the existing on the gravure screen dots is transferred to the paper surface.
- the ink penetrates too deeply into the paper texture, reducing color intensity.
- Voraussetzun ⁇ gen for a good printed image with few defects and high color intensity are as smooth as possible and homoge ⁇ ne surface topography and a coordinated Farbannah ⁇ metechnisch the paper surface.
- base papers are usually smoothed calendering with so-called soft calenders ⁇ , sometimes called Janus.
- This treatment can lead to pinching of the paper surface and thus to its compression, which has a detrimental effect on the resin receptivity.
- the abovementioned properties are substantially influenced by the impregnation of the decorative base paper, ie by the type of impregnating agent used.
- the impregnating resin solutions customarily used for the impregnation of decorative base papers are resins based on urea, melamine or phenolic resins and containing formaldehyde and lead to brittle products having poor tear strength and printability.
- WO 01/11139 is a formaldehyde-free Caribbean Sear ⁇ pollution, consisting of a binder, an aqueous Polymer dispersion and glyoxal proposed, which allows the production of splitting resistant decorative papers.
- the paper impregnated with this composition does not laminate well.
- the invention is therefore based on the object to provide a formal maldehydtransports prepreg which does not have the abovementioned disadvantages and is characterized in particular by good printability and high interlaminar strength from ⁇ .
- a pre-impregnate which is ⁇ it is by impregnation of a base paper with a Tränkharzates containing at least one polymer latex and at least one modified starch having a molecular weight distribution, expressed by a polydispersticiansindex Mw / Mn of at least 6.
- Be ⁇ vorzugt are starches which have a polydispersity index 6 to 23

- the polydispersity index is usually the ratio ⁇ nis of weight and number average molecular weight Mw / Mn specified. It gives information about the width of the molecular weight distribution curve.
- the molecular weight distribution of the modified starches was determined by gel permeation chromatography (GPC) in the usual way from the starch manufacturer. GPC analysis was performed using a chromatograph with kla ⁇ len Shodex KS. The eluent was 0.05 M NaOH at a flow rate of 1 ml / min. Calibration was carried out with pullulan standards with ⁇ be known molecular weights.
- All modified starches used according to the invention are commercially available. These are in particular thermally and oxidatively degraded corn and potato starches.
- the amount of Tränkhar ⁇ zes is preferably 10 to 35 wt.%, But especially 12 to 30 wt.%, Based on the basis weight of the decorative base paper. It has been found that the impregnating resin solution according to the invention is particularly well suited, since it not only leads to improving the nip strength of the paper impregnated therewith, but also with respect to other properties such as printability, paint level or yellowing comparably good or even better results than the state the technology allows. In addition, the otherwise usual when using hydrophilic binder problems when laminating (gluing or gluing with the pad) of the impregnated papers do not occur. This means that the impregnating resin solution according to the invention allows Her ⁇ position of prepregs with good lamination ability. Another advantage is that the prepreg can be inexpensively manufactured at high machine speeds.
- the polymer latex may preferably be a styrene copolymer such as a styrene-acrylic acid ester copolymer, a styrene-vinyl acetate copolymer, a styrene-butadiene or a styrene-maleic acid copolymer. But mixtures of these copolymers can be used. Particular preference is given to polymers which have a high degree of self-crosslinking. But not self-Po ⁇ mers are suitable.

- the starch is first set, either cold that is dissolved at room temperature to a maximum of Tempe ⁇ 60 0 C in the water or is cooked at about 120 to 145 0 C. In this case, an about 40 to 45% suspension with a pH of about 5 to 6 is generated. In the next step, the addition of about 50% is carried out taking into ⁇ supply of the desired solids content and the Mengenver ⁇ holds isses starch / latex weight La ⁇ tex dispersion at a pH value of 5 to 10. In a further step, a pigment made or filling material ⁇ addition.
- the decorative base papers to be impregnated are those which have undergone neither a sizing in the mass nor a heatnlei- mung.
- Typical additives may be wet strength agents, retention aids and fixatives. Divorce decorative base paper under ⁇ to sizing usual papers by the much higher filler or pigment content and the lack of a usual in paper sizing or surface.
- the invention to be impregnated base paper may contain egg ⁇ nen high proportion of a pigment or a filler.
- the proportion of the filler in the base paper can be up to 55% by weight, in particular 8 to 45% by weight, based on the weight per unit area.
