Embodiment

[0033] MDF boards measuring approximately 2 x 3 m are cleaned, smoothed and tempered. The acidic hardener for urea-formaldehyde adhesives (hardener 2547—Akzo Nobel) was applied by means of a roller coating device at ambient temperature with an application weight of about 8 g / m 2 and light initial drying was carried out with an IR irradiator. On this again about 40 g / m was applied with a roller 2 Adhesive layer (urea-formaldehyde adhesive 1206-Akzo Nobel). Lay by roller on still wet adhesive layer with a weight per unit area of ​​60 g / m 2 and press-applied in a calender at a roll temperature of 160 kN / cm and 190° C., wherein the binder was at least partially cured. Here the outer surface of the paper remains unchanged, ie no glue is penetrated. The paper is then cut in the gaps between the boards. The plates are immediately conveyed to a printing station where the decoration is printed on in the first color by means of indirect gravure printing. The second color and the th...

Abstract

A method for producing a decorated laminate having a plate-shaped core made of wood or wood material, a decorative layer on at least one side of the core, and a cover layer having aminoplast on the decorative layer, comprising the following steps: providing the plate-shaped core, fastening a cellulose nonwoven material on at least one side of the core, printing the decoration on the exposed side of the cellulose nonwoven material, attaching at least one curable cover layer on the printed decoration, and curing the curable layers.

Description

technical field [0001] The invention relates to a method for producing a decorative laminate, in particular a laminate having a carrier based on wood material, a decoration and at least one covering or protective layer arranged thereon. Background technique [0002] Such laminates are frequently used, for example, for floors, baseboards and ceiling panels, panels and furniture. Here the decoration can imitate other materials, such as wood, ceramics, natural or artificial stone, or consider an artistic or practical point of view. The decoration is usually protected from wear by a more or less transparent layer of thermosetting plastic. It is also common for the surface of such coverings to be provided with a structure that is spatially associated with the decoration and is referred to as a synchronization hole. [0003] Technological developments to date have mainly resulted in two different classes of materials for the covering layer. So-called lacquer layers are formed f...
