Manufaturing method of incombustible impregnated decorative veneer and incombustible plywood manufactured by the impregnated decorative veneer

摘要

A method for manufacturing incombustible impregnated veneers and an incombustible veneer board produced by the same are provided to secure a fire extinguishing effect by generating carbon dioxide at high temperature by calcium carbonate included in the incombustible impregnated veneer by using the incombustible impregnated veneer in producing the veneer board used for various furniture, interior/exterior materials, and wall surfaces of a building. In the method for manufacturing the incombustible impregnated veneer, an incombustible impregnation solution is produced by adding and mixing calcium carbonate of 60~200wt.% with a thermosetting resin impregnated solution of 100wt.%. A sliced veneer is impregnated with the incombustible impregnation solution to keep the solid content at 30~50% and then dried at 110-150‹C. In addition, a decoration effect is improved by forming impregnated overlay sheet layers(16,17) by laminating impregnated overlay sheets on outer surfaces of upper and lower veneer layers(14,15).
