Embodiment 1

[0114] A premix consisting of approximately 65% ​​by weight of chalk and 35% by weight of PVC was melted in an extruder at approximately 140°C. The premix contains commonly used auxiliary materials, such as lubricants, antioxidants, etc. The premix is ​​extruded while cooling through a profile with dimensions 1300x4 mm.

[0115] Then, the decorative film is calendered in a first step. It is here a PVC film (approximately 80 g / m 2 area weight), the PVC film is printed with wood trim.

[0116] Then spread corundum modified with oligoalkylsilane on it by means of a spreader (15g corundum / m 2 , granularity: F220). Put transparent PVC film (area weight: 50g / m 2 ) is rolled onto it.

[0117] For comparison, manufacture without corundum, but with transparent PVC film (area weight: 96g / m 2 )sample.

[0118] The two transparent films were structured during calendering by means of structured calender rolls. The continuous strip is then cut to specification. In order to improve...

Embodiment 2

[0121] A premix consisting of approximately 65% ​​by weight of chalk and 35% by weight of PVC was melted in an extruder at approximately 140°C. The premix contains commonly used auxiliary materials, such as lubricants, antioxidants, etc. The premix is ​​extruded while cooling through a profile with dimensions 1300x4 mm.

[0122] Then, the decorative film is calendered in a first step. It is here a PVC film (approximately 80 g / m 2 area weight), the PVC film is printed with wood trim.

[0123] Then apply a PU-based primer (about 15g / m 2 , liquid) roll or spray on the decorative film.

[0124] Then spread corundum modified with oligoalkylsilane on it by means of a spreader (15g corundum / m 2 , granularity: F220). Put transparent PVC film (area weight: 50g / m 2 ) is rolled onto it.

[0125] For comparison, manufacture without primer and corundum, but with transparent PVC film (area weight: 96g / m 2 )sample.

[0126] The two transparent films were structured during calendering...

Embodiment 3

[0129] A premix consisting of approximately 65% ​​by weight of chalk and 35% by weight of PVC was melted in an extruder at approximately 140°C. The premix contains commonly used auxiliary materials, such as lubricants, antioxidants, etc. The premix is ​​extruded while cooling through a profile with dimensions 1300x4 mm.

[0130] Then, the decorative film is calendered in a first step. It is here a PVC film (approximately 80 g / m 2 area weight), the PVC film is printed with wood trim.

[0131] Then apply a PU-based primer (about 15g / m 2 , liquid) roll or spray onto the film. The corundum modified with methacrylic silane (15 g corundum / m 2 , granularity: F220).

[0132] The continuous strip is subsequently separated according to specifications or processed further as a continuous strip. A paint structure was applied to the surface, said paint structure consisting of ESH paint (60g / m 2 ) and UV-based topcoats for improved scratch resistance (20g / m 2 )constitute. The firs...

Abstract

The invention relates to a method for producing an abrasion- and water-resistant multilayer panel, in particular an abrasion- and water-resistant floor panel. The method has the steps of providing at least one plastic support panel, in particular a PVC support panel; applying at least one decorative layer onto the at least one plastic support panel; applying at least one primer layer onto the at least one decorative layer; uniformly scattering abrasion-resistant particles onto the at least one primer layer applied onto the decorative layer; and applying at least one cover layer.

Description

technical field [0001] The invention relates to a method for producing a wear-resistant and waterproof multilayer panel, a panel produced by means of the method and a production line for carrying out the method. Background technique [0002] Tiles, wooden planks (such as parquet), laminates, PVC planks and fabrics (such as carpets) are mainly used as floor planks at present. Floor planks made of PVC are generally preferred in public and commercial spaces, but are also preferred in domestic areas due to their resistant properties, ease of installation and low cost. [0003] PVC-based floor planks are divided into several categories and subcategories. Here, in particular, a distinction is drawn between conventional PVC flooring and so-called LVT (luxury vinyl tile) flooring. [0004] Conventional PVC decking basically uses PVC as a substrate with a softener, whereby a flexible product is obtained that can be printed and placed on the floor in a simple manner. Traditional PV...
