Embodiment 1

[0060] After coating adhesive a on one side of film A, dry at 120°C for 2 minutes, attach release film I, and print ink I on the other side, dry and cure at 75°C for 60 minutes. Thin film A is thermoformed at 120℃*15s to make a curved decorative explosion-proof film with R6mm arc chamfer on the long side. After cutting, tear off the release film I and stick it on the inside of the cover plate 1. After the bonding is completed, use 355nm UV light to perform pattern etching from the shell side. Observe the appearance of the laminated product after completion.

Embodiment 2

[0062] After coating adhesive a on one side of the film B, dry it at 120°C for 2 minutes, attach the release film I, and print ink I on the other side, dry and solidify at 75°C for 60 minutes. Thin film B is thermoformed at 120°C for 15s to make a curved decorative explosion-proof film with R6mm arc-shaped chamfer on the long side. After cutting, tear off the release film I and stick it on the inside of the cover plate 1. After the bonding is completed, use 355nm UV light to perform pattern etching from the shell side. Observe the appearance of the laminated product after completion.

Embodiment 3

[0064]After coating adhesive a on one side of film C, dry it at 120°C for 2 minutes, attach release film I, and print ink I on the other side, dry and solidify at 75°C for 60 minutes. Thin film C is thermoformed at 120°C for 15s to make a curved decorative explosion-proof film with R6mm arc-shaped chamfer on the long side. After cutting, tear off the release film I and stick it on the inside of the cover plate 1. After the bonding is completed, use 355nm UV light to perform pattern etching from the shell side. Observe the appearance of the laminated product after completion.

Abstract

The invention provides a thin film and a shell made of the same thereby forming a back shell of an electronic product display and realizing shell protection. The film provided by the invention does not warp in the gluing and printing processes, the problem of adsorption or positioning sliding between films does not occur, and the subsequent processing and production efficiency is not influenced. The film has the advantages of few foreign matters inside, low haze, high full-light transmittance and no influence on the appearance decoration effect. And the molding performance and the fitting performance are excellent, the curved surface molding or fitting requirement can be met, the appearance is free of wrinkles or deformation and other undesirable phenomena before and after molding or fitting, the method can be suitable for plane and curved surface shells and shell protection, and the appearance quality is high. The shell made of the film provided by the invention can be subjected to UVphotoetching, and is suitable for high-end machine types and overseas brand machine types.

Description

technical field [0001] The invention relates to a film and a shell made thereof, in particular to a film used for display back shell and shell protection. Background technique [0002] With the rapid development of the consumer electronics industry, various manufacturers are constantly innovating not only in the functions of electronic products, but also in their appearance designs. Many electronic products on the market have changed from the original metal back shell to the glass back shell. In order to prevent the glass back shell from breaking and splashing, the film and the glass back shell will be used together. And for a more beautiful design effect, many decorative layers will be added on the surface of the film. [0003] However, the adhesive films currently on the market still have many deficiencies in lamination performance or appearance decoration performance. In addition, there are more and more electronic devices with curved screens on the market. Not only the...
