Abstract

Beschrieben wird ein Verfahren zur Herstellung eines Vorimprägnats, das dadurch gekennzeichnet ist, daß ein Rohpapier mit einer Imprägnierflotte imprägniert wird, die a) eine wäßrige Dispersion auf Basis eines Acrylsäureester/Styrol-Copolymers, b) einen Trockenverfestiger auf Basis eines Copolymerisats aus (Meth-)Acrylamid und (Meth-)Acrylsäure und c) Wasser enthält, wobei pro Gew.-Teil trockenem Copolymerisat aus (Meth-)Acrylamid und (Meth-)Acrylsäure etwa 0,3 bis 13 Gew.-Teile trockenes Acrylsäureester/Styrol-Copolymer eingesetzt werden. Das mit dem Verfahren erhältliche Vorimprägnat dient zur Herstellung von Dekorverbundgebilden, wie dekorativen Laminaten und verschiedenen Möbelteilen.A method for producing a pre-impregnate is described, which is characterized in that is that a base paper is impregnated with an impregnating liquor which a) a aqueous dispersion based on an acrylic acid ester / styrene copolymer, b) a dry strength agent based on a copolymer of (meth) acrylamide and (meth) acrylic acid and c) contains water, with per part by weight of dry copolymer (Meth) acrylamide and (meth) acrylic acid about 0.3 to 13 parts by weight dry Acrylic acid ester / styrene copolymer can be used. The one obtainable with the procedure Preimpregnate is used to manufacture decorative composite structures, such as decorative laminates and various furniture parts.
