Recycling of laminate floorings
View Patent ↗Recycling of laminate flooring based on a separation of the panels into particles which are connected with a binder and formed to a new sheet shaped material. A building panel includes a surface layer and a wood fiber based core, and the wood fiber based core includes aluminum oxide particles.
1. A method to recycle floor panels comprising a wood fibre based core, a decorative surface layer comprising a thermosetting resin and aluminium oxide wherein the method comprises the steps of:
mechanical cutting of the panel into particles;
mixing said particles with a binder; and
pressing the mixed particles and binder and thereby forming a sheet shaped material,
wherein the binder is a phenol resin.
2. The method as claimed in claim 1 , wherein the pressing is made under heat.
3. The method as claimed in claim 1 , wherein the method comprises the step of separating particles essentially into a first set of particles comprising substantially wood fibres and a second set of particles comprising substantially melamine before mixing at least the first set of elements with a binder.
4. The method as claimed in claim 1 , wherein the method comprises the step of separating particles essentially into a first set of particles comprising substantially wood fibres and a second set of particles comprising substantially melamine before mixing at least the first set of elements with a binder.
5. A method to recycle floor panels comprising a wood fibre based core, a decorative surface layer comprising a thermosetting resin and aluminium oxide wherein the method comprises the steps of:
mechanical cutting of the panel into particles;
mixing said particles with a binder; and
pressing the mixed particles and binder and thereby forming a sheet shaped material,
wherein the sheet shaped material forms a surface layer arranged on a core.
6. The method as claimed in claim 5 , wherein the method comprises mixing said particles with a melamine formaldehyde resin.
7. The method as claimed in claim 5 , wherein the pressing is made under heat.
8. The method as claimed in claim 7 , wherein the method comprises mixing said particles with a melamine formaldehyde resin.
9. The method as claimed in claim 5 , wherein the method comprises the step of separating particles essentially into a first set of particles comprising substantially wood fibres and a second set of particles comprising substantially melamine before mixing at least the first set of elements with a binder.
10. The method as claimed in claim 6 , wherein the method comprises the step of separating particles essentially into a first set of particles comprising substantially wood fibres and a second set of particles comprising substantially melamine before mixing at least the first set of elements with a binder.
11. The method as claimed in claim 7 , wherein the method comprises the step of separating particles essentially into a first set of particles comprising substantially wood fibres and a second set of particles comprising substantially melamine before mixing at least the first set of elements with a binder.
12. A method to recycle floor panels comprising a wood fibre based core, a decorative surface layer comprising a thermosetting resin and aluminium oxide wherein the method comprises the steps of:
mechanical cutting of the panel into particles;
mixing said particles with a binder; and
pressing the mixed particles and binder and thereby forming a sheet shaped material,
wherein the binder is a melamine formaldehyde resin.
13. The method as claimed in claim 12 , wherein the pressing is made under heat.
14. The method as claimed in claim 12 , wherein the method comprises the step of separating particles essentially into a first set of particles comprising substantially wood fibres and a second set of particles comprising substantially melamine before mixing at least the first set of elements with a binder.
15. The method as claimed in claim 13 , wherein the method comprises the step of separating particles essentially into a first set of particles comprising substantially wood fibres and a second set of particles comprising substantially melamine before mixing at least the first set of elements with a binder.
16. A method to recycle floor panels comprising a wood fibre based core, a decorative surface layer comprising a thermosetting resin and aluminium oxide wherein the method comprises the steps of:
mechanical cutting of the panel into particles;
mixing said particles with a binder; and
pressing the mixed particles and binder and thereby forming a sheet shaped material,
wherein the method comprises the step of separating particles essentially into a first set of particles comprising substantially wood fibres and a second set of particles comprising substantially melamine before mixing at least the first set of elements with a binder.
17. The method as claimed in claim 16 , wherein the pressing is made under heat.
18. A method to recycle floor panels comprising a wood fibre based core, a decorative surface layer comprising a thermosetting resin and aluminium oxide wherein the method comprises the steps of:
mechanical cutting of the panel into particles;
mixing said particles with a binder; and
pressing the mixed particles and binder and thereby forming a sheet shaped material,
wherein the binder is a urea resin.
19. The method as claimed in claim 18 , wherein the pressing is made under heat.
20. The method as claimed in claim 18 , wherein the method comprises the step of separating particles essentially into a first set of particles comprising substantially wood fibres and a second set of particles comprising substantially melamine before mixing at least the first set of elements with a binder.
21. The method as claimed in claim 19 , wherein the method comprises the step of separating particles essentially into a first set of particles comprising substantially wood fibres and a second set of particles comprising substantially melamine before mixing at least the first set of elements with a binder.
