Problems solved by technology

For example, the Chinese patent with the publication number CN104673124A discloses a high-strength anti-blue light protective film, which is coated with an anti-blue light coating and a multi-layer UV glue coating on both sides of the substrate. This anti-blue light protective film only It can resist blue light, has no antistatic and anti-Newton ring effects, and the yellowness of the film surface of the anti-blue light film is relatively large, which is not easy to be accepted by people, which affects the use effect of the protective film

Embodiment 1

[0050] Dissolve 5g of antistatic agent EF-N115 and 3g of EVERSORB type anti-blue light agent with methyl ethyl ketone, then add 50g of UV curable resin FB003 to it, and dilute to a coating solution with a solid content of 30%. The coating solution was coated on a transparent PET substrate, placed in a circulating oven at 80°C for 2 minutes, and then passed through a dose of 500mJ / cm 2 irradiated with ultraviolet light to obtain a multifunctional film layer attached to the substrate layer. Then coat a layer of OCA adhesive layer on the back and cover a layer of release film to get a multi-functional screen protective film. Among them, the thickness of the multifunctional layer is 3 μm, the thickness of the PET base layer is 100 μm, the thickness of the optical adhesive layer is 50 μm, and the thickness of the release film layer is 50 μm.

Embodiment 2

[0052] Dissolve 10g of antistatic agent EF-N115 and 3g of EVERSORB type anti-blue light agent in ethyl acetate, then add 50g of UV-curable resin FB003 to it, and dilute to a coating solution with a solid content of 30%. The coating solution was coated on a transparent PC substrate, dried in a circulating oven at 80°C for 2 minutes, and then passed through a dose of 500mJ / cm 2 UV light irradiation to obtain a multifunctional film attached to the substrate layer. Then coat a layer of OCA adhesive layer on the back and cover a layer of release film to get a multi-functional screen protective film. Among them, the thickness of the multifunctional layer is 3 μm, the thickness of the PET base layer is 100 μm, the thickness of the optical adhesive layer is 50 μm, and the thickness of the release film layer is 50 μm.

Embodiment 3

[0054] Dissolve 10g of antistatic agent EF-N115 and 5g of EVERSORB type anti-blue light agent in methyl ethyl ketone, then add 50g of UV-curable resin FB003 to it, and dilute to a coating solution with a solid content of about 30%. The coating solution was coated on a transparent PET substrate, dried in a circulating oven at 80°C for 4 minutes, and then passed through a dose of 500mJ / cm 2 UV light irradiation to obtain a multifunctional film attached to the substrate layer. Then coat a layer of OCA adhesive layer on the back and cover a layer of release film to get a multi-functional screen protective film. Among them, the thickness of the multifunctional layer is 3 μm, the thickness of the PET base layer is 100 μm, the thickness of the optical adhesive layer is 50 μm, and the thickness of the release film layer is 50 μm.

Abstract

The invention provides a multifunctional screen protection film which sequentially comprises a release film layer, an optimal adhesive layer, a base material layer and a multifunctional layer, wherein the optical adhesive layer is arranged on the release film layer, the base material layer is arranged on the optical adhesive layer, and the multifunctional layer is arranged on the base material layer and comprises an anti-blue-light agent, an antistatic agent and anti-newton's-ring coating resin. The multifunctional screen protection film has antistatic, anti-blue-light and anti-newton's-ring functions and has better anti-blue-light performance and the lower yellowing degree, so that the comfort degree of the screen protection film in use is increased. Besides, the multifunctional screen protection film is high in hardness, large in adhesive force, simple in structure, easy to produce and low in cost.

Description

technical field [0001] The invention belongs to the technical field of electronic equipment, and in particular relates to a multifunctional screen protective film. Background technique [0002] In recent years, the use of electronic products such as mobile phones, tablet computers, and personal computers has become quite popular. During the process of moving and using, a large amount of static electricity will be generated on the surface, making the surface easily susceptible to contact pollution, which will affect the life of electronic products. And normal use will have a great impact. In addition, when multi-layer structures such as film substrates and glass cover plates are assembled, film interference phenomenon often occurs, which easily shows concentric rings with alternating light and dark on the screen surface, that is, Newton rings. The generation of Newton rings will be extremely difficult The earth affects the display effect of the monitor, thus affecting the vi...
