Problems solved by technology

[0002] At present, the mobile phone cases on the market mainly use the spraying process to prepare the pattern of the mobile phone case. Although the color can be sprayed in this way, it is easy to fade and affect the user experience. The mobile phone case using the laser engraving process is also dominated by a single color, and the color is monotonous. , not beautiful enough

Embodiment Construction

[0020] A method for preparing a two-color mobile phone shell pattern,

[0021] Step 1: Detect the surface of the bottom case of the PC material of the mobile phone, and proceed to the next step after confirming that there is no scratch on the surface and that the heterochromatic spots meet the requirements; when testing the surface of the PC material bottom case of the mobile phone, 1. Single point: diameter of the heterochromatic spots ≤0.4mm, 2. Multi-point: Ignore points smaller than 0.1mm. The cumulative value of point size within a 30mm circle is ≤0.40mm, and the interval between each point must be >5mm. Defects with a diameter outside the 30mm circle are regarded as single defects. The allowable cumulative point size of each A side is 0.6mm. In addition, for various paints used, 1. ROHS harmful substance content Pb<1000mg / kg; Cd<100mg / kg; Hg<1000mg / kg; Cr(+6)<1000mg / kg; PBBs<1000mg / kg; PBDEs< 1000mg / kg; the content of harmful substances in the product should not excee...

Abstract

The invention relates to the technical field of phone case processing, in particular to a preparation method of a dual-color phone case pattern. Priming paint is sprayed to a mobile phone PC materialbottom case, and the spraying thickness is 10+ / -5 micrometers; transparent UV priming paint is sprayed to the priming paint, the spraying thickness of the UV priming paint is 20+ / -5 micrometers, the spraying energy is 1000-1200 mj / cm<2>, and drying is carried out under the condition that the temperature ranges from 60 DEG C to 70 DEG C; the UV priming paint is electroplated with an indium target material to form an electroplating layer; transparent protection paint is sprayed, the spraying thickness of the protection paint is 4+ / -2 micrometers, the spraying energy is 300-600 mj / cm<2>, and drying is carried out under the condition that the temperature ranges from 60 DEG C to 70 DEG C; colored paint is sprayed to the protection paint, the spraying thickness of the colored paint is 10+ / -5 micrometers, and drying is carried out under the condition that the temperature ranges from 70 DEG C to 80 DEG C; and a phone case is subjected to laser carving, the electroplating layer is removed through laser carving, and the edge of the laser carving pattern can show the stereo dual-layer colors of the electroplating layer and the colored paint.
