Ultraviolet photolysis adhesive tape

The invention discloses an ultraviolet photolysis adhesive tape which comprises a base material layer, an ultraviolet photolysis adhesive layer and a release layer, and the ultraviolet photolysis adhesive layer is arranged between the base material layer and the release layer. Materials of the base material layer comprise polyvinyl chloride, a plasticizer and a metal salt compound, the total weight of the polyvinyl chloride is 100 parts by weight, the adding amount of the metal salt compound is 1-8 parts by weight, and the metal salt compound comprises a calcium salt compound and a zinc salt compound. The peel strength between the ultraviolet photolysis adhesive layer and a silicon wafer is greater than 10 Newton/inch, and the peel strength between the ultraviolet photolysis adhesive layer and the silicon wafer is less than 0.3 Newton/inch after the ultraviolet photolysis adhesive layer is irradiated by ultraviolet light. 本发明公开一种紫外光解黏胶带，紫外光解黏胶带包括一基材层、一紫外光解黏胶层以及一离型层，紫外光解黏胶层设置于基材层与离型层之间。基材层的材料包括聚氯乙烯、可塑剂与金属盐化合物，
