Title: COMPOSITE SLAB, REUSABLE MOULD FOR PRODUCING SAME AND METHOD FOR CONTINUOUSLY PRODUCING A COMPOSITE MATERIAL, IN PARTICULAR AN INDOOR OR OUTDOOR COVERING
Abstract:
A method for continuously producing a composite material, in particular an indoor or outdoor covering such as a floor, wall or façade covering. A non-adhesive backing strip (A), particularly a silicone-coated paper strip, is unrolled from a feed roller (10), one or a first side of the backing strip (A) is coated with a preferably heat-setting flexible polymer (5), particularly a polyurethane modified epoxy resin or the like, an aggregate layer is deposited on the resulting coated side of said backing strip (A), and the backing strip (A) is heated in order to speed up the polymerisation of said flexible polymer (5). If required, the backing strip may be separated from the resin/aggregate complex before or after the polymerisation step.
