Preparing method for carving simulating UV scratch resisting wood grain decoration film

Abstract

The invention relates to a preparing method for a carving simulating UV scratch resisting wood grain decoration film. The preparing method comprises the technology steps that a PVC face film is prepared; a PVC base material is prepared; two to six polychrome printing is conducted on the surface of the PVC face film according to pattern requirements; color pulp of one color in each set is adopted,a colorful PVC face film is prepared, and finally the printed colorful PVC face film is rolled into a big roll; the printed colorful PVC face film and the PVC base material are heated, pressurized andattached on a double-roller attaching embossing machine, press rollers pressing and attaching the face of the PVC face film are wood splinter embossing rubber rollers, and the temperature of the tworollers can be adjusted to range from 100 DEG C to 200 DEG C; and the attached and embossed PVC decoration film is fed to a printing machine and coated with UV to be conveyed into an oven, secondary temperature increasing is conducted to range from 200 DEG C to 220 DEG C, and PVC face film foaming and cooling are conducted. The carving simulating UV scratch resisting wood grain decoration film prepared through the method has the functions of being capable of achieving the three-dimensional hand feeling, scratch resistance, inflaming retarding, rich colors, carving hollow-out three-dimension and flickering color changing.

Description

technical field [0001] The invention belongs to a preparation method of a PVC decorative film, in particular to a preparation method of an imitation engraving UV scratch-resistant wood grain decorative film. Background technique [0002] Before the present invention was made, the wood grain on the surface of the conventional wood-grain PVC decorative film was directly embossed. It mainly has the following deficiencies: [0003] 1. Since the flame retardant NH-1197 is not added to the decorative film raw materials, there is a disadvantage that the polymer decorative film is easy to burn. [0004] 2. The concave-convexity of the surface of the decorative film is shallow, and it does not have a realistic carving or hollowing out three-dimensional view. [0005] 3. The unevenness of the surface of the decorative film is shallow, and it does not have the function of flashing and changing color under the action of light. [0006] 4. The surface of the decorative film has poor s...
