초록 ▼

The present invention provides a wood board, and a flooring material using this, which uses thin wooden strands as a raw material, has superior surface smoothness, and possesses sufficient strength and rigidity. The wood board in accordance with the present invention comprises a core layer 1 comprising a strand board, and a surface layer 2 comprising a oriented strand board which is laminated on at least one surface of the core layer 1; the surface layer 2 comprises thin wooden strands which are thinner than the thin wooden strands comprising the core layer, and furthermore, the flooring material of the present invention is obtained by laminating a decorative single sheet onto at least one of the surface layers 2 of the wood board. The wood board and flooring material in accordance with the present invention have high strength and superior surface smoothness. Furthermore, if a specified water-repelling agent is added to the binder which is used in molding, it is possible to obtain a wood board having superior water resistance. Furthermore, the present invention makes effective use of raw materials which were conventionally considered to be waste materials, so that it is possible to conserve forest resources, and to reduce raw material costs.
