Abstract

The invention discloses a multifunctional protection film for an electronic product. The multifunctional protection film comprises a PET insulating layer, a metal layer, a wave-absorbing layer and a release material layer, wherein a first adhesive layer is arranged between the PET insulating layer and the metal layer, a second adhesive layer is arranged between the metal layer and the wave-absorbing layer, a third adhesive layer is arranged between the wave-absorbing layer and the release material layer, and the surface, contacting with the wave-absorbing layer, of the metal layer is provided with a plurality of prism lug bosses arranged in parallel. The wave-absorbing layer comprises 100 parts of wave-absorbing powder, 25 to 35 parts of butyl acrylate, 12 to 15 parts of acrylic acid, 20 to 35 parts of 2-ethylhexyl acrylate, 10 to 30 parts of methyl methacrylate, 1 to 3 parts of vinyl acetate, 0.1 to 1 part of 2-hydroxyethyl methacrylate, 0.5 to 2 parts of sodium polyacrylate and 0.4 to 1 part of methylethyl ketone peroxide. The multifunctional protection film prevents excess concentration of heat, is beneficial for heat diffusion, avoids upwarp of the film caused by temperature rise and improves stability of product performance.

Description

technical field [0001] The invention belongs to the technical field of electronic materials, and in particular relates to a protective film for multifunctional electronic products. Background technique [0002] The development of the electronics and communication industry is advancing by leaps and bounds, and more and more electronic and electrical products have entered the lives of ordinary people. While these products improve people's quality of life, they also bring about a prominent problem, that is, the problem of electromagnetic radiation. The electromagnetic waves released by electronic products will bring electromagnetic interference to other electronic devices around them, making them work abnormally; at the same time, they will also cause harm to human health. [0003] At present, miniaturization and high integration are the mainstream trends in the development of electronic products, and the internal space of these products is relatively small. Among the wave-ab...
