Problems solved by technology

Conventional mobile phone film is not anti-static, it is easy to absorb dust during the lamination process or it is difficult to accurately position the screen due to electrostatic adsorption, resulting in a drop in lamination yield; in addition, the anti-static treatment plan for conventional protective film is on the side of the PET film Or coating conductive layers on both sides to achieve anti-static effect, but this solution is likely to cause touch screen failure due to the shielding effect of the above-mentioned conductive layer on the mobile phone, affecting the use of consumers

Embodiment 1

[0029] An antistatic three-layer anti-scratch protective film, the protective layer is the second optical PET film 4 of 50 μm and the second silicone pressure-sensitive adhesive 5 of 15 μm thickness, the viscosity is 1-2g / in; the use layer is the first layer of 100 μm On the optical PET film 1, a 3 μm thick hardened coating 2 is coated, and on the other side of the hardened coating 2, a 25 μm thick first organic silicon pressure-sensitive adhesive 3 is coated, and the viscosity is 5-7g / in; the release layer A third optical PET film 6 of 50 μm was used. Wherein, the first organosilicon pressure-sensitive adhesive 3 contains silver particles of 50-200 nanometers, so that the surface resistance of the adhesive surface is within 10 12 Ω, the static voltage of the use layer is lower than 250 V.

[0030] The anti-static three-layer anti-scratch protective film disclosed by the present invention is applied to the protective film of mobile phones. Nano-silver particles are added to t...

Abstract

The invention discloses an antistatic three-layer scratch resistant protective pasting film. With a three-layer structure, the protective film includes a protective layer, a use layer and a release layer that are stacked together in order. The use layer includes a first optical PET film, a hardened coating and a first organosilicon pressure-sensitive adhesive. The first organosilicon pressure-sensitive adhesive contains 50-200nm nanoscale silver particles. According to the invention, the antistatic three-layer scratch resistant protective pasting film can be applied in protective pasting films of mobile phones. The adding of nano-silver particles into the organosilicon pressure-sensitive adhesive in the use layer ensures high transparency of the protective pasting film (greater than 90%). Meanwhile, with an antistatic function, the protective pasting film cannot absorb dust or occur self-adsorption and affect positioning during pasting, and cannot generate touch screen failure after pasting, thus being able to improve the pasting yield rate of terminal users.

Description

technical field [0001] The invention relates to the field of protective film, in particular to a three-layer anti-scratch protective film with antistatic function, which is applied to the protective film of mobile phones. Background technique [0002] With the rapid development of smart phones, the demand for mobile phone protective films has also increased significantly. Conventional mobile phone film is not anti-static, it is easy to absorb dust during the lamination process or it is difficult to accurately position the screen due to electrostatic adsorption, resulting in a drop in lamination yield; in addition, the anti-static treatment plan for conventional protective film is on the side of the PET film Or both sides are coated with a conductive layer, so as to achieve anti-static effect, but this solution is likely to cause the touch screen of the mobile phone to malfunction due to the shielding effect of the above-mentioned conductive layer, which affects the use of co...
