Panel for forming a floor covering, method for manufacturing such panels and granulate applied herewith
A method for manufacturing panels with at least a substrate and a top layer. The method having the steps of providing a granulate having thermoplastic material and having an average particle size of less than 1 millimeter, forming a substrate layer by strewing the granulate, consolidating the layer between the belts of a continuous press device, and providing the top layer on the substrate.
1. A method for manufacturing panels with at least a substrate and a top layer; said substrate comprising one or more substrate layers and said top layer comprising a printed decor; said method at least comprising:
providing thermoplastic material in the form of a granulate, said granulate having an average particle size of less than 1 millimeter;
forming a substrate layer by strewing said granulate;
consolidating said layer between the belts of a continuous press device;
providing said top layer on said substrate.
2. The method of claim 1 , wherein said average particle size is larger than 25 micrometers.
3. The method of claim 1 , wherein said granulate further comprises at least 50 percent by weight of fillers.
4. The method of claim 1 , wherein said providing a granulate comprises breaking down larger particles.
5. The method of claim 1 , wherein said providing a granulate comprises solidifying thermoplastic material by quenching in a liquid.
6. The method of claim 1 , wherein said thermoplastic material is soft PVC.
7. The method of claim 1 , wherein said providing said top layer comprises melting said substrate layer at least at the surface together with at least a decor film comprising said printed decor.
8. The method of claim 1 , wherein said strewing comprises depositing said granulate on the belts of said continuous pressing device.
9. The method of claim 1 , wherein said method further comprises levelling said substrate by means of a plastisol.
10. The method of claim 1 , wherein said method further comprises levelling said substrate by grinding.
