Problems solved by technology

[0009] Various attempts to regulate and maintain the foam formation at a constant rate have failed because the processes are separated in time and space, whereby regulatory interventions are impossible or only become possible with unacceptably high effort. possible

Embodiment Construction

[0023] The cladding of timber panels should then be based on figure 1 to describe.

[0024] First, 15 to 40g / m of water-based melamine resin 2 The primer layer 2 is applied to the upper side of the core 1 made of wood-plastic mixture or made of wood fibers, wood chips. Then apply a white base 3 to this primer layer 2 as an additional brushing primer, with 20 to 30 g / m 2 The water-based white paint is applied in the white base. The decoration 7 comprises a plurality, preferably two, three or four decorative prints applied one behind the other, for example by offset printing or by means of a digital printing machine (inkjet printing machine). The top layer 8 is made of a waterborne melamine resin-glass sphere mixture with a 10 to 30 g / m 2 applied amount. The melamine resin is preferably a melamine-aldehyde resin and the glass spheres 5 mixed into the resin have a diameter of 60 to 90 μm or 70 to 110 μm. The diameter can of course also range from 60 to 110 μm. After the to...

Abstract

The method involves printing a decor (7) on the top of a wood-based panel. A cellulose-free outer layer (8) made from melamine resin is applied on the decor and in which glass beads (5) are mixed. The outer layer is dried and a wear-protection layer (4) is applied on the top of the outer layer. The drying of outer layer is performed actively. The specific amount of melamine resin-glass bead mixture is applied. The proportion of glass beads in the mixture is of specific value. The diameter of glass beads is in specific range. An independent claim is included for a construction panel.

Description

technical field [0001] The invention relates to a method for processing a wood panel and a structural panel with a core (wood panel) made of wood, said method for printing a decoration onto at least one upper side of said wood panel After gluing to obtain an adhesive-free surface, the surface of the structural panel is treated according to the method described. Background technique [0002] Such wood panels are widely processed and used in many different fields. A particularly large field of use is the application as floor panels. Especially in this application, the timber panel provided with the decoration is subjected to high loads. In order for the timber panels to withstand these loads, the decorative layer must be covered with a protective layer. The protective layer is mostly made of synthetic resin, such as melamine resin, to which various additional materials are added. Tensile stresses occur due to the various layers applied to the wood panels, which can lead to...
