Embodiment 1

[0017] In this embodiment, the structure of the heat-free curved light curing curved screen protector includes a first protective film, an OCA adhesive layer, a main functional layer, a PET resin cured film layer, a surface functional layer and a second protective film from bottom to top. Laminate each layer according to the structure to obtain a heat-free bending light curing curved screen protector, which can be made into the target product after die-cutting, laminating, curing and other processes. The first protective film is an acrylic protective film, and the second protective film is a silicone protective film. The thickness of each film is shown in Table 1.

[0018] Among them, the main functional layer contains thermosetting acrylic resin, isocyanate, polyoxyethylene polyoxypropanolamine ether defoamer, 1073 leveling agent of Moeneng Chemical, and methyl hydroxyethyl cellulose thickener. The mass of isocyanate accounts for 25% of the mass of thermosetting acrylic resi...

Embodiment 2

[0024] In this embodiment, the structure of the heat-free curved light curing curved screen protector includes a first protective film, an OCA adhesive layer, a main functional layer, a PET resin cured film layer, a surface functional layer and a second protective film from bottom to top. Laminate each layer according to the structure to obtain a heat-free bending light curing curved screen protector, which can be made into the target product after die-cutting, laminating, curing and other processes. The first protective film is an acrylic protective film, and the second protective film is a silicone protective film. The thickness of each film is shown in Table 1.

[0025] Among them, the main functional layer contains thermosetting acrylic resin, isocyanate, polyoxypropylene glyceryl ether defoamer, Moeneng Chemical 1074 leveling agent, and hydroxyethyl cellulose thickener. The mass of isocyanate accounts for 3% of the mass of thermosetting acrylic resin; the mass of defoame...

Abstract

The invention relates to a hot-bending-free photo-curing curved screen protective sticker which comprises a first protective film, an OCA adhesive layer, a main body functional layer, a PET film layer, a surface functional layer and a second protective film which are sequentially arranged from bottom to top. The hot-bending-free photocuring curved screen protective sticker can be well attached toa curved screen and the like, and the phenomena of warping, shaping failure, resilience and the like after a traditional protective film is attached are avoided; the hot-bending-free photocuring curved screen protective sticker has good wear resistance, good scratch-resistant effect, good transparency, good temperature resistance and a stable structure, can be prepared into a film with any angle,can be firmly attached to a large-radian curved screen, and can effectively protect the curved screen.

Description

technical field [0001] The invention relates to the technical field of protective films, and more specifically relates to a heat-free curved light curing curved screen protector. Background technique [0002] With the continuous innovation of current smart phone technology, curved screens have begun to enter people's field of vision. The characteristic of curved screens is the super large bending angle (the curved screen of HUAWEI mobile phones is 88°). However, there is currently no strong protection for curved screens. The screen is easily broken or scratched. It is difficult for the traditional tempered film to have a curvature of more than 80%. In addition, the traditional resin protective film is first heat-bent into a curved surface, and then Fitted with the screen of the mobile phone, when facing a curved screen with a large bending angle, problems such as edge warping and springback will inevitably occur. Contents of the invention [0003] The purpose of the prese...
