Abstract
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 aluminium oxide particles.
Claims6
A method to recycle laminate floor panels including a wood fiber based core, a decorative surface layer that includes a thermosetting resin and aluminium oxide, the method comprises:
- a) mechanical cutting of the panel into particles;
- b) mixing said particles with a binder;
- and
- c) pressing the mixed particles and binder and thereby forming a sheet shaped material,
- wherein the method comprises mixing said particles with a melamine formaldehyde resin.
A method to recycle laminate floor panels including a wood fiber based core, a decorative surface layer that includes a thermosetting resin and aluminium oxide, the method comprises:
- a) mechanical cutting of the panel into particles;
- b) mixing said particles with a binder;
- and
- c) pressing the mixed particles and binder and thereby forming a sheet shaped material,
- wherein the pressing is made under heat,
- wherein the method comprises mixing said particles with a melamine formaldehyde resin.
A method to recycle laminate floor panels including a wood fiber based core, a decorative surface layer that includes a thermosetting resin and aluminium oxide, the method comprises:
- a) mechanical cutting of the panel into particles;
- b) mixing said particles with a binder;
- and
- c) pressing the mixed particles and binder and thereby forming a sheet shaped material,
- wherein the method further comprises separating particles essentially into a first set of particles comprising substantially wood fibers and a second set of particles comprising substantially melamine before mixing at least the first set of elements with a binder.
