PROCESS AND INSTALLATION FOR THE PRODUCTION OF STIFF RECYCLABLE SANDWICH-TYPE POLYMERIC PANELS, WITHOUT THE USE OF ADHESIVES, AND THE PANEL PRODUCED |
摘要 |
The present invention describe a process and an installation for the production of stiff recyclable sandwich-type polymeric panels, preferably polypropylene-based panels, and the panel obtained, comprising three lines, in one of which a polymeric polypropylene-based foamed core is produced by extrusion (line A); the structural skins are produced in a second line (line B), which skins are formed by a polypropylene-based lamina reinforced with wood fiber, on which lamina there is applied an also polypropylene-based surface coating layer reinforced with glass fibers; in the third line the structural skins produced in line B are adhered by heat and pressure to the foamed core produced in line A. The sandwich panel produced has a thickness between 7 and 40 mm, an overall density of 400-700 kg/m3 and an elastic modulus of 5-10 GPa.
