Abstract

The invention discloses a protective adhesive tape with a wave absorbing function. The protective adhesive tape comprises a PET insulating layer, a wave absorbing layer and a release material layer. A first adhesive layer is arranged between the PET insulating layer and the wave absorbing layer. A second adhesive layer is successively arranged between the wave absorbing layer and the release material layer. The wave absorbing layer is prepared by mixing the following ingredients (by weight): 100 parts of wave absorbing powder, 20-35 parts of butyl acrylate, 10-20 parts of acrylic acid, 20-35 parts of 2-ethylhexyl acrylate, 10-30 parts of methyl methacrylate, 1-3 parts of vinyl acetate, 0.1-1 part of methacrylic acid-2-hydroxyethyl acrylate, 0.5-2 parts of sodium polyacrylate and 0.4-1 part of methylethyl ketone peroxide. By the protective adhesive tape with the wave absorbing function, utilization rate of a metal layer reflective electromagnetic field is raised, and wave absorbing performance of the protective adhesive tape is remarkably raised. In addition, heat is avoided from being too concentrated. The product is beneficial to heat diffusion.

Description

technical field [0001] The invention belongs to the technical field of electronic materials, and in particular relates to a wave-absorbing sheet for pressure-sensitive adhesive tape. 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-...
