A kind of method of environment-friendly physical vapor deposition secondary color coating film

Abstract

The invention discloses an environment-friendly method for physical vapor deposition intermediate color film plating. The method comprises the following steps: coating a high-temperature-resistant organic thin film with the thickness of 0.06-0.15mm to a to-be-plated base material, drawing the film to an organic matter according to the space shape and size of an intermediate plating area to form a contour pattern of the intermediate plating area, and cutting out the pattern from an organic matter fabric to finish transfer printing of an intermediate plating pattern; processing the transfer printing pattern to ensure that the transfer printing pattern has relatively strong physical adsorption force with a metal surface; cleaning and drying the surface of a workpiece, covering the intermediate plating area by using the obtained high-temperature-resistant organic matter; coating a needed coating layer on the surface of the workpiece by adopting a physical vapor deposition method; and uncovering the organic matter pattern covering the surface of the workpiece to finish the intermediate plating work. According to the method disclosed by the invention, the high-temperature-resistant chemically stable organic thin film is prepared into the intermediate plating pattern which is attached to the intermediate plating area of the workpiece, the organic thin film only needs to be simply torn off after the implementation of physical vapor deposition coating, and an organic solvent is not used in the process of intermediate plating.

Description

Technical field

[0001] The invention relates to a coating method, in particular to an environment-friendly physical vapor deposition intercolor coating method, in particular to a vacuum physical vapor deposition (PVD) coating method. Background technique

[0002] The physical vapor deposition method has been widely used in appearance decoration and surface protective coating preparation. There is an increasing demand for inserting surface patterns and icons into PVD coatings. In the process of physical vapor deposition, part of the surface area of ​​the workpiece is deliberately caused to have PVD coating, and some areas are not PVD coating, so that the desired pattern can be realized. One way to achieve the above intention is to use a special stripping method to remove the part of the coating that does not need to be retained after the entire surface is coated with PVD. However, this method is more difficult to implement, and it is necessary to apply the coating to the area whe...
