Abstract
A building panel (1) including a water resistant core (5) including thermoplastic material 21 and a surface layer (4) including thermosetting resins. Also, production methods to form a board material (1′) with a dry blend of thermoplastic particles 21a in powder form and fillers in powder form and to apply a surface layer (4) with a hot-hot lamination process to a core (5) including such board material.
Claims25
A building panel comprising a core and a surface layer,
- wherein the core comprises a mix of thermoplastic material and wood particles,
- wherein the surface layer comprises a composite material comprising wood particles bonded to each other by a cured thermosetting resin,
- wherein the surface layer is bonded to the core by the cured thermosetting resin, and
- wherein at least some of the wood particles of the core are not completely covered.
A board comprising an upper part possessing an upper surface, a lower part possessing a lower surface, and an intermediate portion located between the upper part and the lower part, wherein the intermediate portion comprises wood particles embedded in a thermoplastic material, and wherein the upper part comprises thermoplastic material and essentially raw wood particles adapted to bond to a thermosetting resin, the intermediate portion having a higher amount of the thermoplastic material than the upper part.
A building panel comprising a core and a surface layer,
- wherein the core comprises a mix of thermoplastic material and wood particles,
- wherein the surface layer comprises a composite material comprising wood particles bonded to each other by a cured thermosetting resin,
- wherein the surface layer is bonded to the core by the cured thermosetting resin, and
- wherein the core comprises an intermediate layer and an upper layer, and wherein the intermediate layer comprises a higher amount of thermoplastic material than the upper layer.
A building panel comprising:
- a core comprising a mix of thermoplastic material and wood particles,
- a surface layer bonded to the core, the surface layer comprising wood particles, thermoplastic material, and a cured thermosetting resin, the wood particles being bonded to each other by the cured thermosetting resin, the thermoplastic material being thermoplastic particles that are spaced apart from one another and surrounded by the bonded wood particle,
- the surface layer being bonded to the core by the cured thermosetting resin, and
- at least some of the wood particles of the core being not completely covered by the thermoplastic material of the core to directly contact the cured thermosetting resin of the surface layer after the surface layer is bonded to the core.
A building panel comprising:
- a core comprising a mix of thermoplastic material and wood particles;
- a surface layer comprising wood particles bonded to each other by a cured thermosetting resin;
- the surface layer being bonded to the core by the cured thermosetting resin of the surface layer;
- and
- at least some of the wood particles of the core being not completely covered by the thermoplastic material of the core to directly contact the cured thermosetting resin of the surface layer after the surface layer is bonded to the core.
