Title: METHOD OF THE PRODUCTION OF EXPANDED POLYSTYRENE BASED COMPACT PARTS WITH INTEGRATED FUNCTIONAL AND/OR DECORATIVE ELEMENTS
Abstract:
Method of the production of expanded polystyrene based compact parts, with integrated functional and/or decorative elements according to the invention consists in that during the core production pre-expanded pearls from expanded polystyrene are introduced to the mold, the functional and/or decorative elements with contact surface being previously treated with the film of liquid pre-polymer, polyester or polyurethane co-polymers of butadiene and styrene and acrylonitnle or other monomers with the chemical formula with the NCO group at the end containing 0,7 - 3,0 parts by weight (optimally 1,2 - 2,2 parts by weight) per 100 parts by weight of pre-polymer and such treated surface is treated with saturated water steam. From pre- expanded pearls a core of expanded polystyrene by reaction with water on NCO groups in layer of liquid pre-polymer at the edge of core and functional and/or decorative element a solid polymer is formed. Surface of integral part can be partially or completely covered by polymer foil, wallpaper, veneer or other functional and/or decorative elements and/or strengthening elements such as mesh, wires, tubes and water or electricity distribution components, or surface layers allowing the integral panel use as well.
