Optical adhesive tape, preparation method thereof and optical adhesive

The invention relates to the field of optical adhesives, and discloses an optical adhesive tape, a preparation method thereof and an optical adhesive. The optical adhesive comprises the following components in parts by mass: 40-50 parts of acrylic resin, 0.0001-0.5 part of a metal complex, 0-10 parts of a photopolymerizable monomer and 0-0.4 part of a photoinitiator, and in the acrylic resin, thecontent of an acrylate copolymer is 30-60%. The main chain structure of the acrylate copolymer comprises methacrylate monomers containing hydrophilic reactive functional groups, wherein the hydroxyl value of the acrylate copolymer is 10-100 mgKOH/g, and the acid value is less than 1 mgKOH/g. The optical adhesive provided by the invention has good segment gap filling capability, can reduce thickness of the optical adhesive tape, and has a characteristic of easy peeling when being bonded with a display screen. 本发明涉及光学胶领域，公开了一种光学胶带及其制备方法、光学胶，其中的光学胶按质量份计包括：丙烯酸类树脂，40～50份；金属络合物，0.0001～0.5份；可光聚合单体，0～10份；光引发剂，0～0.4份；在丙烯酸树脂中，丙
