Abstract
The invention relates to a production method of a melamine veneered decorated board, which comprises the following production steps: firstly, preparing a laminated wood board or a multilayer plywood; then stacking melamine impregnated paper on a veneer and delivering the veneer to a hot-press, controlling the pressure of the hot-press at 10-20 kPa, heating the temperature to be 100-160 DEG C in 10-20 min from the starting temperature of 40-50 DEG C, keeping the temperature at 100-160 DEG C for 5-10 min, gradually lowering the temperature to be 40-50 DEG C, and then compounding the veneer on the prepared laminated wood board or the multilayer plywood after the procedures of gluing, assembly, cold-pressing and hot-pressing. The invention has the advantages that the melamine veneered decorated board is not easy to expand for damp and has long service life, thereby increasing the application area and use amount of the melamine veneered decorated board; melamine veneered decorated paper is firstly solidified and attached on the veneer, thereby not only avoiding the delamination of the laminated wood board and the multilayer plywood but also overcoming the deformation and the damage of the laminated wood board and the multilayer plywood under high pressure.
