Glass-like protective film manufacturing method

Abstract

The invention provides a manufacturing method of a glass-like protective film. The manufacturing method comprises the following steps: cutting a roll material into a sheet; coating the surface of thesheet with an adhesion layer by a first processing means; arranging a material layer on the adhesion layer by a second processing means; arranging a pattern layer on the material layer by a third processing means to form a processed sheet; forming a film sheet from the processed sheet by a cutting means; carrying out injection molding on the film sheet to form a semi-finished product; and performing a trimming means on the semi-finished product to obtain a protective film finished product, so that the protective film finished product with an imitation material effect is formed through the material layer and the pattern layer.

Description

technical field [0001] The present invention relates to a manufacturing process, in particular to a method for manufacturing a glass protective film. Background technique [0002] In recent years, electronic devices such as smartphones and tablet devices have been widely used by the public, and protective stickers used to protect the casings of electronic devices are also widely used. Nowadays, most of the protective stickers are made of tempered glass or plastic film to increase the protection strength and durability. grinding degree. [0003] Furthermore, in order to achieve the effect of decorating the protective sticker, thermal transfer printing is widely used to transfer the pattern to the protective sticker. Most of the methods are to directly transfer the printed ink and glue to the protective sticker after being heated by a hot pressing wheel. Above; a similar thermal transfer printing method has been disclosed in the patent application for “Thermal Transfer Printi...

Problems solved by technology

[0004] However, the transfer pattern needs to be rolled on the protective sticker by a hot pressing wheel, so the existing thermal transfer method can only be applied to flat protective stickers, and cannot completely transfer the design to a 3D protective sticker with curved or multi-angle surfaces On, especially fragile 3D glass, in this way, the quality of the protector will be reduced, and the decorative effect cannot be achieved
