Abstract

The invention discloses a protective adhesive tape with a wave absorbing function. The protective adhesive tape includes a PET insulating layer, a metal layer, a wave absorbing layer and a release material layer. 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 surface of the metal layer, which is contacted with the wave absorbing layer, is provided with several parallel prism lug bosses. A third adhesive layer, a polypropylene film layer and a fourth adhesive layer are successively arranged between the wave absorbing layer and the release material layer. A surface of the fourth adhesive layer, which is contacted with the release material layer, is provided with several convex points. According to the protective adhesive tape with the wave absorbing function of the invention, a utilization rate of a reflection electromagnetic field of the metal layer can be increased; wave absorbing performance of the protective adhesive tape can be significantly improved; and over concentration of heat can be avoided, which is good for heat diffusion.

Description

technical field [0001] The invention belongs to the technical field of electronic materials, and in particular relates to a protective adhesive tape with a wave-absorbing function. 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...
