Problems solved by technology

[0003] At present, for the protection of small glass screens, the existing technology mainly uses tempered glass for protection. However, tempered glass still has the risk of being fragile, and the bonding effect on 2.5D and 3D screens is poor. For 2.5D or 3D screens A more effective protection solution is to use hot-pressed film for protection, but the hot-pressed film has a fixed shape, which is difficult to adjust and inconvenient to use; and for large glass screens, there is no good protection measure in the prior art
More importantly, neither tempered glass nor hot-pressed film can meet the requirements of functional protective film, especially in today's increasingly popular high-end electronic equipment, people's demand for functional protective film is getting higher and higher.

preparation example Construction

[0051] The present invention also provides a method for preparing the functional soft protective film described in the above technical solution, comprising the following steps:

[0052] a) One side of the first substrate layer is coated with a layer of silica gel containing 0.5wt% to 5wt% antistatic agent, and the other side is coated with a layer of resin containing 0.5wt% to 5wt% antistatic agent, which is cured and used Floor;

[0053] b) compounding an adhesive layer on the surface of the second substrate layer, and then compounding the adhesive layer with the antistatic resin layer in the use layer obtained in step a), to obtain a use layer compounded with the first protective film;

[0054] c) Composite the antistatic silica gel layer in the use layer compounded with the first protective film obtained in step b) with the second protective film to obtain a functional soft protective film.

[0055] In the present invention, a layer of silica gel containing 0.5wt% to 5wt% ...

Embodiment 1

[0066] (1) Coating a layer of silica gel containing 2.5wt% antistatic agent (BASF VS03 antistatic agent) on one side of the TPU substrate, and coating a layer containing 2.5wt% antistatic agent (Juli JL-WT antistatic agent) on the other side fluorine-containing polyurethane resin containing 2.5wt% antistatic agent, the silica gel containing 2.5wt% antistatic agent is baked at 170°C for 90s; Then get the usage layer;

[0067] The use layer is a three-layer structure composed of an antistatic silicone layer, a TPU base material layer and an antistatic fluorine-containing polyurethane resin layer, wherein the thickness of the antistatic silicone layer is 20 μm, and the peeling force is 100gf / 25mm; The thickness of the TPU substrate layer is 200 μm; the thickness of the antistatic fluorine-containing polyurethane resin layer is 30 μm, and the preparation method is as follows: 10 parts by weight of the resin is composed of a prepolymer formed by hexafluoropentanediol, and 10 parts ...

Embodiment 2

[0072] (1) Coat a layer of silica gel containing 3wt% antistatic agent (BASF VS03 antistatic agent) on one side of the TPU substrate, and coat a layer containing 2wt% antistatic agent (Juli JL-WT antistatic agent) on the other side fluorine-containing polyurethane resin, the silica gel containing 3wt% antistatic agent is baked at 170°C for 90s; the fluorine-containing polyurethane resin containing 2wt% antistatic agent is baked at 100°C for 75s, and the use layer is obtained after curing ;

[0073] The use layer is a three-layer structure of antistatic silica gel layer, TPU substrate layer and antistatic fluorine-containing polyurethane resin layer compounded in sequence, wherein the thickness of the antistatic silica gel layer is 30 μm, and the peeling force is 100gf / 25mm; The thickness of the TPU substrate layer is 100 μm; the thickness of the antistatic fluorine-containing polyurethane resin layer is 20 μm, and the preparation method is as follows: 10 parts by weight of the...

Abstract

The invention provides a functional soft protecting film. The functional soft protecting film comprises a first protection film, a use layer and a second protection film, wherein the use layer comprises an anti-static silica gel layer composited on the second protection film, a first base material layer composited on the anti-static silica gel layer and an anti-static resin layer composited on thefirst base material layer; the first protection film comprises an adhesion layer composited on the anti-static resin layer and a second base material layer composited on the adhesion layer; the anti-static silica gel layer is prepared from silica gel containing 0.5wt%-5wt% of an anti-static agent by curing, and the anti-static resin layer is prepared from resin containing 0.5wt%-5wt% of the anti-static agent by curing. The functional soft protecting film adopts the anti-static silica gel layer containing the specific quantity of the anti-static agent and the anti-static resin layer containingthe specific quantity of the anti-static agent simultaneously, overall strengthening of a product is realized by cooperation with other specific layer structures, and therefore, the functional soft protecting film can be widely applied to planar or cambered screen protection and has anti-static and self-cleaning functions.

Description

technical field [0001] The invention relates to the technical field of protective films, and more specifically relates to a functional soft protective film and a preparation method thereof. Background technique [0002] With the rapid development of electronic product technology, mobile electronic terminal equipment, such as mobile phones, notebooks, tablet computers, and vehicle-mounted computers, are known and used by more and more people, and their screens are one of the most important devices. In recent years, with the development and popularization of 2.5D and 3D screens, most mobile phones currently use curved glass screens. Although 2.5D and 3D curved glass screens are more expensive for mobile phones, they have a more rounded appearance. The edges and corners are more in line with the aesthetics and experience of consumers, and at the same time enhance the anti-collision performance. [0003] At present, for the protection of small glass screens, the existing techno...
