Furthermore, the finishing coating is the environment-friendly coating, and has the features of being convenient for operation, simple in construction and extensive in applicability and the like.

Description

technical field [0001] The invention belongs to the field of chemical coatings, and specifically relates to a water-based UV-curable vacuum electroplating topcoat; in addition, the invention also relates to a preparation method and an electroplating method of the water-based UV-curable vacuum electroplating topcoat. Background technique [0002] With the improvement of people's living standards, the use of portable electronic products such as mobile phones, digital cameras, digital video cameras, MP3, MP4, etc. is becoming more and more common. The shells of these products all need to have fashionable decorative effect and anti-fouling, wear-resistant and anti-scratch properties, especially the shells of mobile phones need electronic shielding and anti-radiation functions, and the vacuum coating process makes these all possible. [0003] Vacuum plating is a physical deposition phenomenon. That is, argon gas is injected in a vacuum state, and the argon gas hits the target ma...
