Composite wood board and method for its manufacture

摘要

The board (5) has a core made of composite wood such as medium density fiberboard and high density fiberboard or composite wood-plastic mixture, and a decorative layer provided on an upper surface of the core. A transparent resin layer covers the decorative layer and contains particles such as corundum with high rigidity for increasing wear resistance, where the resin layer has pyrogenic silicon dioxide particles (6) whose size ranges from 1 to 100 nanometer (nm). The amount of the silicon dioxide particles is 0.5 to 10 gram per meter square. An independent claim is also included for a method for manufacturing a composite wooden board.
