Preparation method of colored surface compressive plate

The invention relates to a preparation method of a colored surface compressive plate, in particular to solving the technical problem of providing a manufacturing method of a colored surface compressive plate featuring high surface layer density, dimensional stability, strong operability and diverse colors which are close to the colors of natural precious wood. The technical scheme for solving theproblem is as follows: the method comprises the following steps: (1) drying and controlling the water content between 8% and 15%; (2) notching surface layer and controlling the width of grooves between 0.5mm and 1.0mm; (3) dipping dye, namely soaking part of the surface layer with notches of the plate into water-soluble dye solution at concentration of 0.5-2.0% for impregnation; (4) softening andcontrolling the softening temperature between 120 DEG C and 140 DEG C; (5) compressing surface and controlling the compression ratio between 15% and 50%, the hot pressing temperature between 160 DEG Cand 180 DEG C and the unit pressure between 1.5MPa and 4.5MPa; and (6) setting. The method is suitable for such fields as furniture manufacturing, indoor decoration and the like.
