Abstract

The invention discloses an anti-static optical adhesive which is prepared from the following raw materials in percentage by weight: 1-5% of an antistatic agent, 30-60% of polyurethane acrylate, 20-50% of an acrylate monomer, 5-10% of unsaturated polyester, 0-2% of a photoinitiator (excluding 0%), 3-6% of a crosslinking agent and 1-5% of a coupling agent. The preparation method comprises the following steps: (1) adding polyurethane acrylate, part of the acrylate monomer and unsaturated polyester into a reaction kettle, stirring and heating in a water bath to a stable backflow state; (2) uniformly mixing residual raw materials, putting into the reaction kettle and stirring for polymerization reaction; and (3) finishing the polymerization reaction to obtain the anti-static optical adhesive. The anti-static optical adhesive disclosed by the invention is a colorless transparent viscous liquid matter, has the characteristics of being anti-static, high in light transmittance, high in curing speed, low in cure shrinkage rate and low in haze and the like and can be widely applied to fitting an optical protective thin film base material and a release film.

Description

technical field [0001] The invention relates to an antistatic optical adhesive, which belongs to the technical field of chemical industry. Background technique [0002] In recent years, with the rapid development of the modern electronics industry, LCD TVs, tablet computers and smart phones have been widely used, which has brought more and more electrostatic radiation hazards. Therefore, antistatic protective films with certain optical properties have attracted more and more attention. Antistatic optical adhesive is a special adhesive used for bonding transparent optical components. It is an essential key material in the production process of antistatic protective film. It is mainly used for laminating optical protective film base material and release film. The main features of this anti-static optical adhesive are: anti-static, high light transmittance, fast curing speed, low curing shrinkage, low haze, etc. [0003] At present, there are few reports on optical adhesives ...
