Problems solved by technology

This will bring the following problems: (1) The more color layers of the coating layer, the more dispersed the color difference of the coating layer, which will lead to lower yield
(2) Because the coating layer needs to use high refractive index materials, but its thickness is generally only between 5-100nm, a slight change in its thickness will cause a large color difference, because the more coatings, the color levels displayed by the coating layer will result feel bad
(3) When the decorative film is pasted on the inner surface of the 3D plastic shell, the more layers are required, the thicker the coating layer is, and the easier the coating layer is to break in areas with greater stress and strain, resulting in poor appearance
(4) Moreover, there are no protective measures for the edge of the front cover of the colored plastic mobile phone and the camera, which is easy to damage the camera and the front cover during the installation process

specific Embodiment approach 1

[0032] like Figure 1-6 As shown, a hole 7 for installing a camera is provided on the front cover 6 of the colored plastic mobile phone, a volume receiver hole 9 is provided at the front end of the front cover 6 of the colored plastic mobile phone, and a hole 9 is provided in the middle of the front cover 6 for The display area position 10 of the display screen is installed, the back end of the colored plastic mobile phone front cover 6 is provided with a mechanical or touch-sensitive button position 11, and the four corners and four sides of the colored plastic mobile phone front cover 6 are fixedly connected with reinforcing ribs 8. The reinforcing ribs 8 and the colored plastic mobile phone front cover 6 are seamlessly connected or integrally formed, the reinforcing ribs 8 arranged on the four corners of the colored plastic mobile phone front cover 6 are rectangular, and the reinforcing ribs 8 disposed on the four sides of the colored plastic mobile phone front cover 6 are a...

specific Embodiment approach 2

[0035] The main difference between the second embodiment and the first embodiment is:

[0036] (1) In this embodiment, the reinforcing ribs 8 and the colored plastic mobile phone front cover 6 are integrally formed.

[0037] (2) If image 3 As shown, in this example, the texture layer 2 is arranged on the inner surface of the outer shell layer 1, that is, in contact with the reflective layer 4; the thickness of the outer shell layer 1 is 5 mm, the thickness of the functionalized coating layer 3 is 40 μm, and the colored plastic mobile phone front cover 6 The L*a*b* value of is overall white.

[0038] (3) In this embodiment, the protective cover and the hole are seamlessly and fixedly connected, but the protective cover is provided with a sloped edge that forms an angle of 45° with the colored plastic mobile phone front cover 6, such as Image 6 shown. Of course, it can be the slope side of other radians, not limited to 45°.

specific Embodiment approach 3

[0039] The main difference between the third embodiment and the first embodiment is:

[0040] (1) In this embodiment, the reinforcing ribs 8 and the colored plastic mobile phone front cover 6 are integrally formed.

[0041] (2) If Figure 4 As shown, in this example, the textured layer 2 is arranged on both sides of the outer shell layer 1, that is, the textured layer 2 is in contact with the reflective layer 4 and the hardened coating 3 respectively; the thickness of the outer shell layer 1 is 2.5 mm, and the functionalized coating 3 The thickness is 20um, and the L*a*b* value of the colored plastic mobile phone front cover 6 is generally blue.

[0042] (3) In this embodiment, the protective cover and the hole are seamlessly and fixedly connected, but the protective cover is provided with a sloped edge that forms an angle of 45° with the colored plastic mobile phone front cover 6, such as Image 6 shown. Of course, it can be the slope side of other radians, not limited to ...

Abstract

The invention discloses a colored plastic mobile phone front cover manufacturing process which is characterized in that compared with an existing colored plastic mobile phone front cover, a hole site (7) for mounting a camera is formed in the colored plastic mobile phone front cover (6), and fixedly connected reinforcing ribs (8) are arranged at four corners and four edges of the colored plastic mobile phone front cover (6); the reinforcing rib (8) and the colored plastic mobile phone front cover (6) are seamlessly and fixedly connected or integrally formed, the colored plastic mobile phone front cover (6) sequentially comprises a shading layer (5), a reflecting layer (4), a shell layer (1), a texture layer (2) and a functional coating (3), and according to actual requirements, L * a * b * values of the colored plastic mobile phone front cover (6) comprise a * and b * values of the shell layer (1) and L * values of the reflecting layer (4). A series of problems existing in the colored plastic mobile phone front cover manufactured by the mobile phone shell front cover manufacturing process are solved.

Description

technical field [0001] The invention relates to the field of manufacturing a colored plastic mobile phone front cover, in particular to a manufacturing process of a colored plastic mobile phone front cover. Background technique [0002] In the process of making the front cover of colored plastic mobile phones, the color difference formula of the color difference meter is commonly used in the industry: CIE L*a*b* color space, L*,*a,b* is the chromaticity value representing the color of the object , that is, the color space coordinates of the color, and any color has a unique coordinate value; where L* represents light and shade (black and white), *a represents red and green, and b* represents yellow and blue; it is a modern color difference assessment according to the International Lighting Association. The standard color difference formula recommended by (CIE) and calculated by instruments and computers can be expressed by precise numbers. [0003] The color L*, a*, b* of t...
