Abstract
A method for impregnating decorative papers which are used for producing highly abrasion-proof laminate floor materials. 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%.
Claims3
A laminate panel made in accordance with a method comprising:
- taking paper;
- damping and impregnating the paper with an amino resin by the use of metering rollers;
- additionally spraying onto the damped wet paper an additional layer of amino resin in a dispersion containing an abrasive substance;
- wherein the final area density relative to the dry mass of raw paper amounts to 100% to 250%;
- and
- pressing the impregnated paper to form the laminate panel.
A laminate panel made by using a damped wet paper with an additional layer produced by spraying onto the damped wet paper an amino resin in a dispersion containing an abrasive substance;
- and the damped wet paper with the additional layer thereon is used to form the laminate panel.
