Abstract
The invention relates to a floor or wall panel and a method for producing such panel. The panel according to the invention comprises a core layer comprising at least one composite material, said composite material comprising at least one inorganic material, and at least one polymeric binder, wherein a weight ratio of the inorganic material to the polymeric binder is at least 3:1. The core layer further comprises a coupling agent which is configured for bonding with the inorganic material and/or the polymeric binder.
Claims28
A floor or wall panel comprising:
- at least one core layer comprising at least one composite material, said composite material comprising:
- at least one inorganic material, and
- at least one polymeric binder,
- wherein a weight ratio of the inorganic material to the polymeric binder is at least 3:1, and wherein the core layer further comprises:
- at least one organofunctional coupling agent,
- wherein said at least one organofunctional coupling agent is bound to at least one inorganic material and/or to at least one polymeric binder.

A method of producing a floor or wall panel, comprising the steps of:
- a) providing an at least one inorganic material, an at least one polymeric binder and an at least one organofunctional coupling agent, wherein a weight ratio of the inorganic material to the polymeric binder is at least 3:1;
- b) feeding a mixture of the at least one inorganic material, the at least one polymeric binder and the at least one organofunctional coupling agent to an extruder;
- and
- c) extruding the mixture such that an extruded core layer is formed wherein said at least one organofunctional coupling agent is bound to the at least one inorganic material and/or to the at least one polymeric binder.
