<p>A process for manufacturing a decorative mainly isometric thermosetting laminate (1) comprising an isometric core (2), a primary surface layer (10) and optionally a secondary surface layer (20). 85 parts by weight of preferably organic particles are mixed with 15-85 parts by weight of a thermosetting resin such as phenol-formaldehyde resin, melamine-formaldehyde resin, urea-formaldehyde resin or mixtures thereof under powerful kneading in an extruder so that friction heat forms. The thermosetting resin is hereby bonded to or impregnating the particles. The particles possibly bonded to one another are parted whereby an agglomerate of resin and particles is formed. The particle/resin mixture is then dried to a water content of below 10 %. The dried particle/resin mixture is then evenly distributed and continuously or discontinuously compressed in one or more steps under heat and pressure so that the resin finally cures, whereby an isometric core (2) is formed. The core (2) is during or after the pressing provided with a primary (10) and optionally a secondary (20) surface layer. The invention also relates to a laminate obtained through the process and use thereof.</p> |
