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 aluminum oxide particles.
Claims21
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.
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.
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.
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.
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.
