Abstract

The invention concerns a method for treating paper strips for making paper to be impregnated with synthetic resins, comprising the following steps: inserting (3) in the paper (1) a resin-based mixture (A); consecutively to or simultaneously with the insertion (3) of mixture (A), treating (4) at least one surface of the paper strip (1) by applying a resin-based mixture (B); drying (5) the paper; treating (6) the surface of at least one of the surfaces of the paper strip (1) by applying a resin-based mixture (C); drying (5) the paper. After drying and optionally glazing (7), the resulting surface provides for high fidelity printing. The invention further concerns paper to be impregnated with synthetic resins obtained by said method. The invention is useful for high pressure and/or low pressure lamination of supports such as particle boards, woodfibre boards, plywood sheets or the like.

MULTI-PHASE TREATMENT OF PAPERS INTENDED FOR LAMINATING SUBSTRATES SUCH AS PARTICLEBOARD, WOOD FIBERBOARD, PLYWOOD, OR OTHERS. ;APPLICATION APPLICATION APPLICATION PLACER: MR. ERNST HELLER ;The invention aims to significantly improve the quality of these papers and simultaneously reduce the use of certain fillers in these technical papers. These improvements primarily consist of obtaining a paper surface optimally suited for printing, without preventing the printed paper from absorbing the necessary amount of resin for lamination onto substrates such as particleboard, fiberboard, plywood, or others. Rotary gravure printing of decorative papers is characterized by a somewhat imprecise reproduction of wood grain in the photographic reproduction of wood structures.

10 L'invention permet d'obtenir une surface différente des papiers décor, permettant ainsi, avec l'utilisation d'encres aqueuses d'impression modifiées, de fixer l'image photographique avec une meilleure fidélité. 10 The invention makes it possible to obtain a different surface of decorative papers, thus making it possible, with the use of modified aqueous printing inks, to fix the photographic image with better fidelity.

Ces papiers sont obtenus avec le traitement suivant. Dans un papier-décor avec des valeurs 15 techniques standard mais avec des charges en pigment réduites, est inséré à l'intérieur un mélange de résines melamine-formaldéhyde, urée formaldéhyde, acryliques auto-reticulant et durcisseurs. Après séchage suit un deuxième traitement avec un mélange de résines melamine-formaldéhyde, urée formaldéhyde, acryliques auto-reticulant, durcisseurs, et pigments. Après séchage, on obtient une surface permettant une impression de haute-20 fidélité. These papers are produced using the following process. A mixture of melamine-formaldehyde resins, urea-formaldehyde resins, self-linking acrylics, and hardeners is inserted into a decorative paper with standard technical values but reduced pigment loads. After drying, a second treatment is carried out using a mixture of melamine-formaldehyde resins, urea-formaldehyde resins, self-linking acrylics, hardeners, and pigments. After drying, a surface suitable for high-fidelity printing is obtained.
