The technical scheme improved further in technique scheme is as follows:
1, in such scheme, the thickness of described first adhesive layer is less than the thickness of the second adhesive layer.
2, in such scheme, described PET thickness of insulating layer is 40 ~ 80 microns.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model high reliability protective tapes, which raises the utilization ratio of metal layer reflection electromagnetic field, and arranging of metal level can form re-absorption effect, significantly improves the absorbing property of material, the use of insulation layer and PET film layer improves the intensity of material on the one hand, secondly, its PET insulation layer plated surface opposing with the first adhesive layer is covered with metallic silver layer, and metal level, between metallic silver layer and suction ripple layer, further increases the absorbing property of material, again, several high lug bosses arranged in parallel and low lug boss, high lug boss and low lug boss are arranged alternately, interval is left between adjacent high lug boss and low lug boss, greatly reduce the interference of electromagnetic field, substantially increase the homogeneity of absorbing property and electromagnetic field further, and be disposed with the first acryl glue adhesion coating between suction ripple layer and separated type material layer, graphite radiating layer, second acryl glue adhesion coating, strong evacuation absorbs owing to inhaling ripple layer the heat that electromagnetic field causes in a large number, thus ensure that the reliability of the performance of product, and the defect such as coming unstuck of preventing adhesive layer from high temperature causing.
