Abstract:
A method for manufacturing a floor covering, comprising the following steps:wetting of particles with a solution that contains at least one aromatic-free organic peroxide and white oil, wherein said particles contain uncrosslinked or partially cross-linked elastomer comprising a polyolefin having a density of <0.918 g/cm.sup.3 as a polymeric binder in form of a grinding stock or granules,mixing of said wetted particles with a powder mix containing a polyethylene (PE) powder for the production of free-flowing particles,placing said free-flowing particles on a strip, and after pre-compressing of said particles, heating the pre-compressed particles to a temperature at which the peroxide has a sufficiently lengthy stability, andpress-molding the pre-heated particles in a suitable device at a temperature whereby the half life period of said peroxide is decreased in such a manner that cross-linking initiated by said peroxide occurs simultaneously to obtain a flat product.
