Resilient floor covering with regenerative, dirt-repellent surface
A resilient floor covering with a regenerative, dirt-repellent surface contains a matrix based on natural and/or synthetic materials and at least one substance that is capable of migrating within the matrix and the amount of the substance is in excess of its compatibility in the matrix. The resilient floor covering according to the invention preferably has an embossed surface and a matrix, into which a particulate material with greater hardness than that of the matrix is incorporated. The floor covering is characterized by improved soiling behavior and increased wear resistance.
1. A floor covering comprising a composition including a binder, a plasticizer and a substance capable of migration within the composition, wherein the binder comprises polyvinyl chloride (PVC), the plasticizer is in an amount of at least about 12 wt. % based on PVC, and the substance capable of migration is present in an amount of from about 1.5 wt. % to about 15 wt. % based on the binder, and wherein the floor covering has a profile with elevations and recesses, the average spacing between profile peaks in the centerline is more than about 200 μm and less than about 1000 μm, and the difference in height between the elevations and the recesses is from about 20 μm to about 200 μm.
2. The floor covering according to claim 1 , wherein the substance capable of migration is a wax-like substance.
3. The floor covering according to claim 2 , wherein the wax-like substance is selected from the group consisting of a partially synthetic wax, a fully synthetic wax, a natural wax, a modified natural wax and mixtures thereof.
4. The floor covering according to claim 2 , wherein the wax-like substance comprises an amide wax.
5. The floor covering according to claim 1 , wherein the floor covering further comprises a substrate and a coating, the coating comprising the binder, plasticizer and substance capable of migration.
6. The floor covering according to claim 5 , wherein the coating comprises a particulate material having a hardness greater than the hardness of the PVC of the coating.
7. The floor covering according to claim 1 , wherein the composition comprises a particulate material having a hardness greater than the hardness of the PVC.
8. The floor covering according to claim 7 , wherein the particulate material comprises a polymer.
