Abstract
Methods and equipment to apply a decorative surface on a building panel wherein the surface includes a mix of fibres, binders, wear resistant particles and pigments. Layers may be applied as separate layers with equipment that applies essentially only one of the materials in the surface mix. A method of forming a surface layer on a substrate, the method including forming a first layer of a first material, applying a second layer of a second material on the first layer, mixing the first and second layers into a mix comprising the first and the second material, and applying the mix on a substrate for forming a surface layer.
Claims22
A method of forming a surface layer of a building panel, the method comprising:
- forming a binder layer comprising at least 80% by weight of particles of a thermoplastic binder;
- forming a wear resistant layer comprising at least 50% by weight of wear resistant particles;
- and
- pressing, under heat and pressure, the wear resistant layer and the binder layer to combine and mix the wear resistant particles of the wear resistant layer and the thermoplastic binder of the binder layer to form the surface layer.
