Description

Shell and its preparation method

technical field

The present disclosure relates to the technical field of shell processing, in particular to a shell and a preparation method thereof.

Background technique

With the increasing popularity of smart phones and the continuous development of digital imaging technology, today's smart mobile communication devices often have large-size touch screens and high-pixel camera functions. The optical coating technology widely used in touch screens and camera devices has been widely used and developed.

The optical film formed by optical coating is one or more layers of film coated on the surface of optical parts to change the surface characteristics of optical parts. With the expansion and extension of the optical coating process, this process has also been applied to the decoration of electronic product casings. Using the characteristics of optical coating: thin, non-conductive, metallic luster, and capable of producing various color effects, combined with the fine mold UV embossing process and diaphragm transfer process that have emerged in recent years, glass, plastic, and glass fiber composite materials And other different materials can show a metal-like gorgeous effect.

However, while the optical coating brings a cool metallic effect, it will cause the problem that the finished casing has different colors when viewed from different angles. When making white, black, and dark blue, there is no obvious problem, and when making bright colors, this problem is obvious. For example: when the finished product is required to have a pink effect and a strong metallic feel, it is usually achieved by adjusting the color of the optical coating layer. The finished product produced in this way is pink when viewed from the front, but when viewed from the side, it will be affected by the color of the film layer and turn yellow, which seriously affects the stability of the color of the product.
