Method for impregnating decorative papers

摘要

The invention relates to a method for impregnating decorative papers which are used for producing highly abrasionproof laminate floor materials, wherein the decorative paper is firstly moistened with an amino resin and is thus impregnated. The amount of resin applied is controlled using dosing rollers. In addition, a layer comprised of an amino resin is sprayed with a special dispersion onto the moistened decorative paper. The final mass per unit area with regard to the dry mass of the base paper ranges from 100 % to 250 %.
