Non-backing OCA optical film with blue-ray resisting effect and preparation method of non-backing OCA optical film

The invention discloses a non-backing OCA optical film with a blue-ray resisting effect and a preparation method of the non-backing OCA optical film and aims to achieve the purposes of optimizing the functions of a toughened glass film and improving the protection performance of the toughened glass film. The non-backing OCA optical film comprises a silica gel layer, wherein a heavy release film is arranged at the bottom of the silica gel layer; an OCA blue-ray resistant material high-viscosity layer is introduced onto the silica gel layer; a medium release film is arranged on the OCA blue-ray resistant material high-viscosity layer; the release force of the heavy release film is 8-15 g, and the release force of the medium release film is 3-10 g; the silica gel layer is 20-50 [mu]m in thickness; the OCA blue-ray resistant material high-viscosity layer is 30-80 [mu]m in thickness. According to the non-backing OCA optical film with the blue-ray resisting effect and the preparation method of the non-backing OCA optical film, an OCA optical adhesive has blue-ray resisting performance, and meanwhile, the non-backing optical adhesive is reduced in thickness, does not influence the integral appearance of a mobile phone and has a better application hand feeling.
