Problems solved by technology

The production process of the existing two-color and double-textured PVD film on the surface of the metal substrate is: metal substrate—cleaning—A color PVD coating—spraying UV ink—exposure—developing—removing uncured ink—sandblasting—cleaning—B color PVD coating -Removing paint—cleaning—coating anti-fingerprint film, this process requires two different PVD coatings, because the PVD coating process is time-consuming, especially when the PVD coating is performed twice, the process time will be further increased, thus resulting in longer process time and cost Increased manpower and material resources, low product yield
At the same time, the complexity of the process also limits the variety of colors
If two layers of PVD coatings with different colors are carried out in the same furnace at one time, the problem of film explosion will often occur. Technology has important practical significance and market application prospects

Abstract

The invention relates to the technical field of pattern processing and discloses a method of forming a double-color double-texture PVD film layer on a metal substrate and the metal substrate obtainedthereby. The method comprises the following steps: (1) carrying out primary PVD coating treatment on the metal substrate to form a bottom film layer and a top film layer different in color on the metal substrate; (2) designing a needed pattern on the top film layer, and coating shielding printing ink to the pattern region to be cured; (3) carrying out sand blasting treatment on the substrate obtained in the step (2); (4) removing the top film layer exposed in a non-pattern region; and (5) removing the shielding printing ink cured in the pattern region. The method can plate the double-color double-texture PVD film layer on the metal substrate at one time within a same furnace body without a film exploding phenomena, so that the PVD coating step is reduced, the time is shortened greatly, thecost is lowered, and the product yield is increased obviously.

Description

technical field [0001] The invention relates to the technical field of pattern processing, in particular to a method for forming a two-color and two-texture PVD film layer on a metal substrate and the metal substrate obtained therefrom. Background technique [0002] With the development of science and technology, people have higher and higher requirements for the two-color and two-texture PVD (Physical Vapor Deposition) film layer made on the surface of the metal substrate. The production process of the existing two-color and double-textured PVD film on the surface of the metal substrate is: metal substrate—cleaning—A color PVD coating—spraying UV ink—exposure—developing—removing uncured ink—sandblasting—cleaning—B color PVD coating -Removing paint—cleaning—coating anti-fingerprint film, this process requires two different PVD coatings, because the PVD coating process is time-consuming, especially when the PVD coating is performed twice, the process time will be further incr...
