METHOD FOR OBTAINING A PREFABRICATED PANEL FOR OUTDOOR AND INDOOR DECORATION

摘要

A silicone, resin or metal mould is produced on a surface of the material which the decorative panel is intended to reproduce, for example a surface of bricks, natural stone etc. A mould release agent and then a pigmentation layer based on iron oxides or any other type of pigments suitable for the material to be reproduced are applied to said mould. A mixture of acrylic polymer and calcium sulphate is then introduced into the mould and is spread uniformly until a thickness of between 2 and 10 mm is achieved. Finally, the mould is filled with expanded polyurethane in order to compact the panel. This produces a large panel which has the same appearance as the material intended to be reproduced, is fireproof and has a high coefficient of both thermal and acoustic insulation.
