Flexible all-coating soft film and preparation method thereof

Abstract

The invention relates to the technical field of protective films, and particularly relates to a flexible all-coating soft film and a preparation method thereof. The flexible all-coating soft film comprises a film protecting layer, a using layer and a stripping layer which are sequentially adhered from top to bottom; the protecting film layer comprises a base material layer and a film protecting glue layer which are sequentially adhered from top to bottom; the using layer comprises a self-repairing layer, a flexible soft film layer and a using glue layer which are sequentially adhered from topto bottom; the lower surface of the film protecting glue layer is adhered to the upper surface of the self-repairing layer; and the lower surface of the using layer is adhered to the upper surface ofthe stripping layer. The flexible all-coating soft film provided by the invention has smooth hand feeling and large stripping force, a curved screen can be all coated, relatively good resilience and self-repairing effect can be achieved, scratch marks can be repaired automatically, and the service life of the flexible all-coating soft film is prolonged. The preparation method provided by the invention is simple, the operation control is convenient, conventional production processes are simplified, the production efficiency is high, the production cost is low, the prepared product is high in yield and stable in quality, and the preparation method is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of protective films, in particular to a flexible all-encompassing soft film and a preparation method thereof. Background technique [0002] With the popularization of electronic devices designed with 2.5D and 3D curved edges on the screen, and the development of flexible mobile electronic terminal equipment, protective films are required to protect the screens, and most of the current protective films have better Softness, but the softer the protective film is, the easier it is to scratch. The scratches caused not only affect the appearance of the protective film, but also affect the normal use of the protective film. At the same time, the current protective film has low adhesive force and weak adhesion, which makes the protective film easy to fall off from the screen, and with the increase of the use time of the protective film, the edge of the protective film is prone to warping, white edges, etc. Affect ...

[0002] With the popularization of electronic devices designed with 2.5D and 3D curved edges on the screen, and the development of flexible mobile electronic terminal equipment, protective films are required to protect the screens, and most of the current protective films have better Softness, but the softer the protective film is, the easier it is to scratch. The scratch marks not only affect the appearance of the protective film, but also affect the normal use of the protective film

At the same time, the current protective film has low adhesive force and weak adhesion, which makes the protective film easy to fall off from the screen, and with the increase of the use time of the protective film, the edge of the protective film is prone to warping, white edges, etc. Affect the use effect and shorten the service life

[0003] In addition, in the current production process of protective film, it is necessary to cover a layer of isolation film during the production and winding process to prevent the glue layer from sticking together, resulting in bubble marks, wrinkles, etc., which will affect the yield of the protective film.
