【 摘 要 】

Primer helps to enhance the adhesive force of the tape and the substrate. Different reinforcements on different substrates have different amplitudes. The order of increase in initial bond strength is PC> PVC> PP> PET>> PE. The order of increasing holding power after 7 days is PP> PVC> PC> PET>> PE. The primer has better adhesion on the modified tape than on the unmodified tape. High temperature and humidity are not conducive to the enhancement of the primer. The polar substrate has a more pronounced reinforcing effect. Ultraviolet (UV) irradiation can initiate group polymerization cross-linking to increase the tackiness. With the increase of irradiation power, the adhesive strength of the adhesive layer gradually increased and reached stability at around 3000mJ. The effect of ultraviolet irradiation on the shearing force of the adhesive tape on the glass substrate is significant,the decrease is greater than 60%. With the increase of the irradiation power, the maximum deformation of the tape decreased, and the rebound rate remarkably increased from 10.7% to 62.5%.
