Problems solved by technology

However, plastic shells and painted shells cannot present a good metallic texture
On the other hand, because the vacuum coating technology itself is relatively complicated and difficult to precisely control, the color of the metal vacuum coating layer formed on the surface of the shell in the prior art is limited. Compared with baking paint, anodizing and other processes, the color of the vacuum coating layer is not enough. Rich, severely limited its competitiveness in the field of decorative coating

Embodiment Construction

[0016] see figure 1 , the casing 10 of a preferred embodiment of the present invention can be a casing of a mobile phone. The casing 10 includes a base 11 , a bonding layer 13 and a color layer 15 . The combination layer 13 is disposed on the surface of the substrate 11 , and the color layer 15 is disposed on the surface of the combination layer 13 .

[0017] The substrate 11 may be metal material or non-metallic material such as glass or plastic.

[0018] The bonding layer 13 is formed on the surface of the substrate 11 by magnetron sputtering. The bonding layer 13 is a titanium metal film with a thickness of 0.1-0.3 μm. The color of the bonding layer 13 is a light tone that does not affect the color of the color layer, such as silver, white, off-white and other light tones.

[0019] The color layer 15 is a Ti-O-N film, which is formed by magnetron sputtering. The thickness of the color layer 15 is between 0.3-0.8 μm. This color layer 15 presents deep blue, and the chro...

Abstract

A shell. The shell contains a matrix, an anchor coat and a color layer. The anchor coat is formed on the surface of the matrix. The color layer is formed on the surface of the anchor coat. The color layer is a Ti-O-N film. L* coordinate figure of the chromatic region presented by the color layer in the CIE LAB color system is between 52 to 57; a* coordinate figure is between -15 to -25; and b*coordinate figure is between -10 to -18. The invention also provides a manufacturing method of the above shell. The shell presents a dark blue appearance, and the color of a vacuum coating layer is abundant.

Description

technical field [0001] The invention relates to a housing and a manufacturing method thereof, in particular to a dark blue and metallic housing and a manufacturing method thereof. Background technique [0002] With the continuous advancement of technology, various electronic devices such as mobile phones, personal digital assistants (PDA, Personal Digital Assistant), and computers are also developing rapidly, and their functions are becoming more and more abundant. In order to make the casing of the electronic device rich in color, traditionally, colored plastics can be used to form the colored plastic casing, or a color layer is formed on the surface of the casing of the electronic device by spraying paint. However, plastic shells and painted shells cannot present a good metallic texture. On the other hand, because the vacuum coating technology itself is relatively complicated and difficult to precisely control, the color of the metal vacuum coating layer formed on the sur...
