METHOD TO PRODUCE A SURFACE COVERING

摘要

The present invention relates to a method to produce a polymeric sheet comprising the steps of providing an acid-based polymer, providing a neutralizing agent, the neutralizing agent being selected from the group consisting of an organic metallic compound, a metallic salt of a fatty acid, and an ionomer, or a mixture thereof, providing a processing oil, mixing said acid-based polymer, said neutralizing agent, said processing oil, to obtain a polymeric composition, and processing said polymeric composition to form a polymeric sheet. The polymeric sheet may be used as a component, or as a substrate, of a surface covering. The polymeric sheet may also be used to form polymeric particles which are component of so-called “homogenous”, or substrate-free, surface covering.

主权项

1. A method to produce a polymeric surface covering, said method comprising the steps of:
providing an acid-based polymer; providing a neutralizing agent selected from the group consisting of an organic metallic compound, a metallic salt of a fatty acid, and a terpolymer ionomer, or a mixture thereof; providing a processing additive; mixing said acid-based polymer, said neutralizing agent and said processing additive, to obtain a polymeric composition; processing said polymeric composition to form a polymeric sheet; granulating said polymeric sheet into polymeric particles; depositing said polymeric particles directly on a band-shape moving carrier of a belt press device; heating the polymeric particles on said band-shape moving carrier; pressing under heat the polymeric particles to form said polymeric surface covering.
