Problems solved by technology

[0003] The current optical adhesive film has a single function and weak anti-electromagnetic radiation performance
The conductive filler endows the optical adhesive with electromagnetic shielding ability. Common electromagnetic shielding materials are electromagnetic shielding materials containing metal layer interlayers or doped with metal particles, but the combination of these metals or nanomaterials with optical adhesives is not firm, and their Inhomogeneous dispersion in the medium leads to incomplete absorption or reflection of electromagnetic waves, which easily causes secondary electromagnetic radiation pollution, resulting in poor use and protection performance, and it is difficult to meet the needs of users

Abstract

The invention belongs to the technical field of optical cement, and provides an electromagnetic wave radiation resistant optical cement and a preparation method thereof to solve the problems that the electromagnetic wave radiation resistant performance of the optical cement is weak and the combination of a nano material and the optical cement is not firm. According to the electromagnetic wave radiation resistant optical cement, an acrylate adhesive compounded with Co40Fe40B20 and an acrylate adhesive compounded with graphene are alternately laid, then a heavy release film and a light release film are attached to the two faces of the acrylate adhesive compounded with Co40Fe40B20 and the two faces of the acrylate adhesive compounded with graphene respectively, and the acrylate adhesive compounded with Co40Fe40B20 and the acrylate adhesive compounded with graphene are the same in laying number; the acrylate adhesive compounded with Co40Fe40B20 at a time and the acrylate adhesive compounded with graphene at a time are laid as one layer, and the laying layer number is 3-5, so that the phenomena that nanoparticles are agglomerated and the bonding stability of the nanoparticles and the adhesive is not strong are avoided, the mechanical property of the optical adhesive is improved, an absorption-reflection-reabsorption process can be formed in the optical adhesive, and an efficient electromagnetic radiation wave effect is realized.
