Problems solved by technology

However, the cost of this coating process is high, the adhesion of the coating is poor, and the coating layer is prone to peeling off from the plastic parts.
In addition, due to the limitations of the machines required for coating, it is impossible to achieve large-area plastic sheet coating, so the production efficiency of this vacuum coating process is low

Embodiment Construction

[0012] The present invention is described further below:

[0013] (1) Prepare the screen printing machine, plastic sheet, screen plate and ink required for printing. The ink includes color transparent ink and silver mirror ink. It is PET or PC sheet, and the color of the ink can be adjusted according to customer requirements.

[0014] (2) First, print the colored transparent ink on the plastic sheet, the thickness of the squeegee is 5u, the squeegee uses a 70-degree hard squeegee, the color transparent ink has a viscosity of 22P, the printing angle is 45 degrees, and the printing speed is 3 gears. Printing pressure is 2Kg f / cm 2 ; Ensure the color stability of transparent colored transparent ink by controlling the viscosity of colored transparent ink and printing parameters.

[0015] (3) Enter the hot air tunnel for drying, the temperature of the tunnel is 70°C, the speed is 3 m / min, and the drying time is 3 minutes;

[0016] (4) Print silver high-gloss mirror ink again. Th...

Abstract

The invention relates to a printing technology of a mobile phone color mirror. According to the technology, transparent color ink and silver highlight mirror ink are used for achieving the color mirror effect through printing. The printing technology includes the steps that 1 a screen printing machine, a plastic sheet, a screen printing plate and ink which are required by printing are prepared, wherein the ink comprises the transparent color ink and silver highlight mirror ink; 2 the transparent color ink is printed on the plastic sheet; 3 the plastic sheet enters a hot air tunnel to be dried; 4 the silver highlight mirror ink is then printed on the plastic sheet; 5 the plastic sheet enters the hot air tunnel to be dried; 6 at last, the plastic sheet enters a drying oven to be dried in a reinforcing mode. By using the printing technology, the mobile phone color mirror effect is achieved, a printed product has high brightness, the mirror is obvious in metal effect, rich in color and high in saturability, and therefore the printing technology can meet the requirements for product quality and performance of clients; meanwhile, compared with a traditional coating technology, the production cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a mobile phone screen printing process, in particular to a mobile phone color mirror printing process. Background technique [0002] At present, the mobile phone industry generally uses vacuum coating to achieve a color mirror effect, which plays a certain decorative role. This kind of coating effect has various colors, high brightness, and obvious metal effect, and is widely used on the surface plastic parts of mobile phones. However, the cost of this coating process is high, the adhesion of the coating is poor, and the coating layer is prone to peeling off from the plastic parts. In addition, due to the limitations of the machines required for coating, large-area plastic sheet coating cannot be achieved, so the production efficiency of the vacuum coating process is low. Contents of the invention [0003] The purpose of the present invention is to provide a color mirror printing process, which can realize the colo...
