Abstract

The invention discloses a preparation method for a BOPET (biaxially oriented polyester) high-imitation metal wiredrawing VCM film. The method includes: conducting surface wiredrawing treatment on one side of a transparent BOPET film; coating one surface without surface wiredrawing treatment by a polyurethane UV curable paint, carrying out UV photo-curing and heat curing, and performing natural cooling to obtain a surface hardened coating; coating the surface subjected to surface wiredrawing treatment with a model SC-400 pre-aluminizing prime coat to obtain a fastness enhanced coating; conducting vacuum aluminizing processing on the fastness enhanced coating to obtain a vacuum aluminized layer; and coating the aluminized surface of the vacuum aluminized layer with a model SC-500 topcoat, thus obtaining an antioxidant protective coating. Single-layer BOPET is adopted as a film main material, thus reducing the dosage of a raw material film, saving the production cost, prolonging the product life and improving the tolerance to various adverse conditions. The film obtained by the method has the visual effects of an imitated metal wire drawing board, thus realizing the purpose of high simulation of different material wiredrawing metal boards.

Description

technical field [0001] The invention relates to a preparation method of a BOPET high imitation metal wire drawing VCM film. Background technique [0002] Non-ferrous metal, non-metal sheet and non-ferrous metal and non-metal composite sheet are more and more widely used in industry and life due to resource saving, easy processing and low cost. In particular, the application of thin plates is more extensive, and it is used in automobiles, refrigerators, washing machines, elevator wall panels, high-end furniture and room partitions, etc. At first, the board was processed into the required shape and then printed or sprayed to obtain a beautiful appearance. However, the appearance effect obtained by this non-planar printing and spraying process is limited, the process technology is complicated, and the process is not environmentally friendly. In recent years, in the household appliance industry, composite plastic films on the surface of steel plates have gradually emerged to re...
