Example Embodiment

[0036] Example 1:

[0037] 1. Exposure and development

[0038] A transparent PC film sheet with a thickness of 0.188 mm and a length and width of 105×148.5 mm is selected, and the PC sheet is a film sheet provided by Bayer in Germany. The water-resistant photosensitive glue is uniformly coated on the first surface of the sheet and dried naturally at room temperature. The photosensitive glue is a single-liquid photosensitive glue, and the photosensitive glue adopts the water-resistant W series W-300F provided by Tianling Fine Chemical Company. Then paste the patterned film negative on the first surface of the sheet, and expose it under ultraviolet light. The exposure light source is a metal halide lamp (iodine gallium lamp) with a power of 3000 watts. The exposure time depends on the selected photosensitive glue and light source. , Make sure the exposure time is 1-1.5 minutes. Excessive exposure will over-sensitize the photosensitive adhesive, and the film will harden, and the fo...

[0062] Example 3:

[0063] 1. Exposure and development

[0064] A transparent PET film sheet with a thickness of 0.1 mm and a length and width of 105×148.5 mm is selected, and the PC sheet is a film sheet provided by Bayer in Germany. Coat the water-resistant photosensitive glue uniformly on the first surface of the sheet and dry naturally at room temperature. The photosensitive glue is a two-component photosensitive glue. The photosensitive glue adopts the water-resistant W210 series photosensitive glue and photosensitive agent provided by Tian Ling Company. (First dissolve the sensitizer in water according to the mass of 1:10 formula, then mix it in the latex 5 parts larger than the aqueous solution, fully stir, leave it for 1-2 hours, and use it after the bubbles disappear), and then paste the patterned film film on The first surface of the sheet is exposed under ultraviolet light. The exposure light source is a metal halide lamp (iodine gallium lamp) with a power of 3000 watts...

Abstract

The invention provides a shell having an effect of a pattern with gradient color. The shell comprises a transparent sheet and a transparent pattern, wherein the transparent pattern is formed on a first surface of the transparent sheet and has the effect of gradient color; a plastic layer is adhered to the first surface of the transparent sheet; and the transparent pattern is combined with the plastic layer. The invention also provides a manufacturing method for the shell having the effect of the pattern with the gradient color. According to the shell having the effect of the gradient pattern with gradient color and the manufacturing method for the shell, the shell is manufactured by sheet preparation, dyeing, demolding, forming and punching and in-mold injection, so that the shell is easy and convenient to manufacture; only the local part of the transparent pattern rather than the whole transparent sheet has the effect of the gradient color; therefore, the achieved effect of the gradient color is nature in transition and exquisite; and simultaneously, an inner lateral surface of the shell is formed by combining the transparent pattern layer with the gradient color and the plastic layer and is protected by an outer surface (a second surface) of the transparent sheet, so that the pattern with the gradient color is difficult to scrape and fade.

Description

technical field [0001] The invention belongs to the field of surface decoration and manufacturing of plastic shells, in particular to a shell with a gradient color pattern effect and a manufacturing method thereof. Background technique [0002] The replacement of electronic products is getting faster and faster, especially mobile phone products, not only the functions of communication, display, and photography of the mobile phone itself, but also new techniques and technologies for surface decoration of mobile phone shells are emerging in an endless stream. Most of the mobile phone casings on the market are mainly made of plastic. The coloring and surface texture decoration of plastic can be completed during plastic molding. However, in order to increase the life of the product and improve the aesthetics, the surface is generally subjected to secondary processing and various decorations. deal with. At present, most of the gradient decorations on the surface of mobile phone ...
