Description
Technical Field
The utility model relates to the field of colored plastic mobile phone rear cover manufacturing, in particular to a colored plastic mobile phone rear cover.
Background
In the process of manufacturing the colored plastic mobile phone rear cover, a color difference formula of a used color difference meter is commonly used in industry: CIE L a b color space, L a, b are colorimetric values representing colors of objects, i.e. color space coordinates of the colors, and any color has a unique coordinate value; wherein L represents brightness (black and white), a represents red and green, and b represents yellow and blue; is a modern color difference assessment according to the standard color difference formula recommended by the International Commission on illumination (CIE) and is calculated by measuring with instruments and computers, and can be represented by precise numbers.
The color L, a and b of the colored plastic mobile phone rear cover is generally realized by a coating layer of a decorative film. When the color of the colored plastic mobile phone rear cover is darker, the coating layer is more complex, the more layers are needed, and the thicker the coating layer is. This brings about the following problems: (1) the more the number of the color layers of the coating layer is, the more the chromatic aberration of the coating is dispersed, which results in lower yield. (2) Because the coating layer needs to use a material with a high refractive index, but the thickness of the coating layer is generally only 5-100nm, and a slight change of the thickness of the coating layer can cause a large chromatic aberration, because the more coating layers, the poorer color gradation displayed by the coating layer is caused. (3) When the decorative film is attached to the inner surface of the 3D plastic shell, the more the number of layers is required, the thicker the coating layer is, and the more easily the coating layer is broken in a region with larger stress and strain, which results in poor appearance. (4) Moreover, the edge of the rear cover of the colored plastic mobile phone and the camera part have no protective measures, so that the camera and the rear cover plate are easily damaged in the installation process.
