Problems solved by technology

Moreover, the traditional electroplating process produces a large amount of sewage and consumes a large amount of electricity and water. A fully automatic circulation electroplating production line can process about 20,000 square meters of electroplating film in one month and discharge about 2,000 tons of sewage.
So much sewage wastes a lot of water resources and seriously pollutes the human ecological environment, so it is urgent to improve or replace the existing electroplating process

Abstract

The invention discloses a silk-screen printing method of a plastic base material. The silk-screen printing method of the plastic base material comprises the following steps that a LOGO is printed on one side of a PET (explosion-proof film) base material; then translucent ink is printed on the same side, printed with the LOGO, of the base material in a silk-screen mode, and a translucent layer is formed; then a line layer is printed on the upper surfaceof the translucent layer in a UV transfer printing mode; then nano-metal ink is printed on the upper surface of the line layer in a silk-screenmode to form a nano-metal layer; then protecting black oil (2 lines) is printed on the upper surface of the nano-metal layer in a silk-screen mode; vacuum patching are carried out; and finally, finished products are formed by CNC cutting. According to the silk-screen printing method of the plastic base material, the problem that red color and other colors of PVD electroplating can not be realizedis solved due to the fact that the self-made translucent ink and the nano-metal ink are adopted; the production process is simplified, the production cost is greatly reduced and the production capacity is increased, the product performance is stable and the through rate is high, especially the resistance value test, the resistance value reaches over 4,000 megohm while an extremity is not reached;and meanwhile, the silk-screen printing method is tested through a domestic first-second line brand real machine, and a antenna signal is not completely affected.

Description

technical field [0001] The invention belongs to the technical field of plastic surface treatment methods, and in particular relates to a screen printing method for plastic substrates. Background technique [0002] With the development of the easy-going economy and the improvement of the quality of life of the people, consumers have higher and higher requirements for the quality of electronic products. Secondly, the appearance design and packaging of products have also received more and more attention. Especially the shells of electronic products must not only be durable, And be stylish. [0003] At present, the shells of many electronic products will have a pattern layer printed on the shell base material, and then vacuum electroplating is performed on the pattern layer to form a coating layer, and then a background ink layer is printed on the coating layer, specifically: PET (explosion-proof film) Substrate→printing LOGO→printing nano transparent color→UV transfer printing...
