Zusammenfassung: | The invention belongs to the technical field of special adhesives, and discloses a high-bonding-force UV adhesive for a polarizing film and a preparation method of the high-bonding-force UV adhesive. The UV adhesive comprises the following components in percentage by weight: 30%-65% of a polyurethane acrylate prepolymer; 30%-55% of a monofunctional acrylate monomer; 2%-8% of a photoinitiator; and 3%-7% of a coupling agent. The preparation method comprises the following steps: uniformly stirring and mixing the monofunctional acrylate monomer and the photoinitiator, sequentially adding the coupling agent and the urethane acrylate prepolymer, and uniformly stirring and mixing to obtain the high-adhesion UV adhesive for the polarizing film. According to the UV adhesive disclosed by the invention, the specific combination of the urethane acrylate prepolymer, the monofunctional acrylate monomer and the coupling agent is adopted, so that compared with a traditional PSA pressure-sensitive adhesive, the obtained UV ad |
