Problems solved by technology

Both the edge and the screen glass are designed to be curved. In order to adapt to this curved edge, the screen protective film currently on the market is mainly a protective film made of polyethylene terephthalate (PET), but PET The material itself is relatively hard, and it will rise when it is attached to the curved edge, which will affect the use effect; and the existing PET protective film has a single function and cannot meet people's individual needs

preparation example Construction

[0047] The invention provides a preparation method of a luminous protective film that can be attached to arc edges, comprising the following steps:

[0048] A) One side of the substrate layer is coated with UV-curable adhesive, and after UV-cured, a substrate compounded with a UV-curable layer is obtained; the UV-curable adhesive includes acrylate prepolymer resin, free radical curing monomer and photoinitiators;

[0049] B) printing the luminous glue on the other side of the base material compounded with the UV hardened layer in step A), and forming a luminous layer on the base material after heating and curing;

[0050] C) Coating viscose on the surface of the luminous layer, and forming a viscose layer after curing;

[0051] D) Attaching a peeling layer on the surface of the adhesive layer for use; compounding a protective film layer on the surface of the UV hardening layer of the use layer to obtain a luminous protective film that can be attached to arc edges.

Embodiment 1

[0066] Mix 30 parts of butanone, 30 parts of propylene glycol methyl ether acetate, 50 parts of hexanediol diacrylate, 30 parts of epoxy acrylic resin, 15 parts of polyurethane acrylic resin, 4 parts of benzophenone and 1 part of triethanolamine to obtain Diluted UV curable adhesive.

[0067] Take a PET base material with a thickness of 20 μm, and coat one side of the PET base material with a UV curable adhesive with a thickness of 4 μm. After heating in an oven at 50°C, it is irradiated with a UV lamp for UV curing to obtain a base material with a UV hardened layer on one side. UV lamp energy is 500mJ / cm 2 .

[0068] Mix the silicone pressure-sensitive adhesive and the luminous powder according to the mass ratio of 1000:10, and use the method of ultrasonic dispersion and physical stirring to fully stir the glue for 1 hour to mix the glue evenly, and filter the glue with a 15 μm filter element to obtain the luminous glue liquid;

[0069] The luminous glue is printed on the ...

Embodiment 2

[0072] Mix 30 parts of butanone, 30 parts of propylene glycol methyl ether acetate, 60 parts of hexanediol diacrylate, 30 parts of epoxy acrylic resin, 15 parts of polyurethane acrylic resin, 2 parts of benzophenone and 1 part of triethanolamine to obtain Diluted UV curable adhesive.

[0073] Take a PET base material with a thickness of 80 μm, and apply UV-curable adhesive on one side of the PET base material with a thickness of 3 μm, heat it in an oven at 90°C, and then irradiate it with a UV lamp for UV curing to obtain a base material with a UV hardened layer on one side. UV lamp energy is 800mJ / cm 2 .

[0074] Mix the silicone pressure-sensitive adhesive and the luminous powder according to the mass ratio of 1000:20, and use the method of ultrasonic dispersion and physical stirring to fully stir the glue for 1 hour to mix the glue evenly, and filter the glue with a 15 μm filter element to obtain the luminous glue liquid;

[0075] The luminous glue is printed on the othe...

Abstract

The invention provides a noctilucent protection film capable of fitting with an arc edge. The noctilucent protection film comprises a stripping layer, an adhesive using layer composited on the stripping layer, a noctilucent layer composited on the adhesive using layer, a base material using layer composited on the noctilucent layer, a UV hardening layer composited on the base material using layer and a protection film layer composited on the UV hardening layer, and the UV hardening layer is made from a material comprising acrylate prepolymer resin, free radial curing monomer and a photoinitiator. The UV hardening layer containing acrylate prepolymer and the noctilucent layer are adopted, so that fitting effect of the protection film can be well guaranteed, the protection film is less prone to edge rising, and noctilucent patterns are formed; experimental results show that hardness of the protection film is 3-4 H, stretching force is 13-30 gf / 25mm, stripping force is 8-20 gf / 25mm, light transmittance is greater than or equal to 94%, and haze is less than 1%.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a luminous protective film that can be attached to arc edges and a preparation method thereof. Background technique [0002] With the development of the electronics industry, many smartphones have a better visual experience for the screen. Both the edge and the screen glass are designed to be curved. In order to adapt to this curved edge, the screen protective film currently on the market is mainly a protective film made of polyethylene terephthalate (PET), but PET The material itself is relatively hard, and it will rise when it is attached to the curved edge, which will affect the use effect; and the existing PET protective film has a single function and cannot meet people's individual needs. Contents of the invention [0003] The purpose of the present invention is to provide a luminous protective film that can be attached to the curved edge and its pre...
