example 1

[0210] In this example, the final product has a decorative surface texture achieved by embossing the paper.

[0211] The following raw materials were used:

[0212] ●Powdered melamine resin

[0213] ●70-110 micron powdered alumina

[0214] ●colored pigment

[0215] HDF / MDF boards are mechanically separated, including wood fibers of natural resins,

[0216] Process operation:

[0217] - Drying and humidity control.

[0218] The wood fibers are dried to a humidity suitable for processing, eg 5-8%.

[0219] - sieving

[0220] Screening operations are used to separate and classify fibers into those suitable for further processing and those that require further size reduction by mechanical grinding.

[0221] -grinding

[0222] The fiber fraction with large fibers is ground to a usable size and recycled to the screening operation.

[0223] -mix

[0224] The raw materials are mixed into compositions suitable for the different layers such as skin, core and balance layers usi...

example 2

[0255] The process described below relates to surfaces on core panels (SOC), in which the surface layer is produced on a separate pre-processed core. In this preferred embodiment the panel has a decorative surface layer of about 0.4mm and a total thickness of about 8mm.

[0256] The following raw materials were used:

[0257] ●Powdered melamine resin

[0258] ●Alumina

[0259] ●pigments

[0260] ●wood fiber

[0261] ●High-density fiberboard (HDF) as the core

[0262] ●Backing paper as a balancing layer

[0263] Process operation:

[0264] The drying and humidity control, sieving, grinding and mixing operations are essentially the same as those for the IFP panels described above.

[0265] - surface layer

[0266] The surface layer of this product is based on melamine resin (such as Kauramine 773 from BASF in Germany), aluminum oxide (such as ZWSK 180 from Treibacher in Austria), black pigment (such as Bone Black from Alfort & Cronholm in Sweden) and wood fiber sieved in...

Abstract

A flooring panel (1) comprising a core (6) and a surface layer (5), the surface layer (5) comprising cork particles (14) or wood fibres (14) comprising lignin resin, melamine resin as binder (19), colour pigments (15), and aluminium oxide as wear resistant particles (12), all components being homogenously mixed, and the core (6) comprising fibres and binder and being provided with a mechanical locking system (4) at its edges and a rear balancing layer (7). Also disclosed is a method of manufacturing said flooring panel by - homogenously mixing the dry particles of the surface layer; - scattering them on an embossed pressure matrix; - applying the core layer as scattered or prefabricated layer on the surface layer; - applying a balancing layer as scattered or prefabricated layer on the core layer; - pre-pressing the panel; - printing and brusching the surface layer; - forming the panel by a further pressing and heating step; - machining the mechanical locking system.

Description

technical field [0001] The present invention generally relates to the field of fiber-based panels with wear-resistant surfaces for building panels, preferably for floor panels. The invention relates to building panels with such a wear-resistant surface and to a manufacturing method for producing such panels. [0002] Application field [0003] The invention is particularly applicable to floating floors formed from floor panels having a wood fiber core and a decorative wear-resistant surface. The following description of the prior art, the problems of the known systems and the objects and characteristics of the present invention (as a non-limiting example) is therefore firstly directed to this field of application, in particular floors similar to conventional floating wood fiber laminate floors field. The invention does not exclude floors glued down on the subfloor. [0004] It should be emphasized that the invention can be used as a panel or as a surface layer, for example...
