THE INVENTION REFERS TO AN IMPROVED COMPOSITE MATERIAL, ESPECIALLY TO A COMPOSITE PLASTER / CELL FIBER MATERIAL WITH AN IMPROVED WATER RESISTANCE, WHICH IS ESPECIALLY USEFUL TO MANUFACTURE CONSTRUCTION PRODUCTS. SPECIFICALLY, THE PRESENT INVENTION REFERS TO A WOODEN PLASTER / FIBER CONSTRUCTION BOARD, IMPREGNATED WITH SILICONE, THAT PRESENTS AN IMPROVED WATER RESISTANCE, DUE TO THE ADDITION OF A SILOXAN EMULSION AND, PREFERIBLY, A CATULATION EMULSION PLASTER AND WOOD FIBER, DURING THE MANUFACTURING PROCESS OF THE BOARD. |
