The invention relates to a method for preparing a carved
wood grain-simulated PVC decorative film. The method comprises the following technological steps: preparing a PVC face film; preparing a PVC substrate; carrying out two to six sets of
color printing on the surface of the PVC face film according to the pattern demands; adopting each set of color
slurry, and entering the next set of
color printing after printing each set of colors and
drying the PVC face film at a temperature of 140 to 160 DEG C; preparing the colorful PVC face film; coiling the printed colorful PVC face film into a large coil; heating, pressing and jointing the printed colorful PVC face film and the PVC substrate on a dual-roller jointing
embossing machine, making pressing rollers used for pressing the colorful PVC face film surface be wood thorn
embossing rubber rollers, and adjusting the temperature of both rollers to between 100 and 200 DEG C; directly loading the jointed and embossed PVC decorative film into a
drying box to carry out secondary heating to 200 to 220 DEG C, and foaming the PVC face film; and cooling the PVC face film. The carved
wood grain-simulated PVC decorative film prepared by the method has the advantages of
flame retardant function, lifelike sculpture, hollow three-dimensional view and flash discoloration functions.
