Embodiment Construction

[0029] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention, but not to limit the scope of application of the present invention.

[0030] Please refer to figure 1 , a method for developing a vehicle-grade automotive switch button surface film, the process is as follows:

[0031] The automobile switch button adopts PVD process to coat the surface of the automobile switch button to form a film layer. The PVD process flow is as follows: first, trim the surface of the automobile switch button, and then spray a layer of primer on the surface of the automobile switch button by painting, Drying and curing to form a primer layer, using PVD technology to coat the primer layer, the specific operations are as follows: place the vehicle switch button in the vacuum chamber of the magnetron sputtering device, pass argon gas, and start the magnetron spu...

Abstract

The invention discloses a film on the surface of a car-specification part.The film comprises a primer layer, a coating layer, an intermediate coat layer and a finishing coat layer, wherein the coating layer uses physical vapor deposition (PVD) for film formation, the primer layer and the finishing coat layer are sprayed by UV paint, and the UV paint contains photoinitiator absorbent.The film has the advantages that the film can be stored in an environment with relative air humidity being larger than 90% and temperature being larger than 85 DEG C for more than 70 hours, and the film is thin and has a highlight effect.The invention further provides a development method of the film.The development method has the advantages that the coating process is improved to solve the problem that films formed by the conventional PVD process cannot satisfy the car-specification requirements, and the PVD process is applied to the forming method of the film on the surface of the car-specification part.

Description

technical field [0001] The invention relates to a film layer on the surface of a vehicle-grade part and a development method thereof. Background technique [0002] At present, the surface film formation methods of automobile switch buttons include electroplating and painting. The thickness of the layer is not conducive to the next step of laser engraving treatment, and after laser engraving, the film layer in the closed ring icon on the surface is easy to fall off. Technical requirements and aesthetics. [0003] Physical vapor deposition (PVD) technology is a new type of surface film formation technology. Sputtering coating is a main coating method of PVD technology. This method is to ionize argon gas into argon ions by glow discharge under vacuum conditions. Argon ions bombard the target, and the sputtered target particles are deposited on the surface of the sample to form a thin and glossy coating. [0004] When PVD technology is applied to surface coating, the conventi...
