[0029] preparation:
[0030] Each component is taken according to the prescription of the reservoir layer and the pressure-sensitive adhesive layer, and dissolved in cyclohexane to make latex. The plastic-coated aluminum foil was used as the backing layer, and the reservoir layer substrate was coated on it to a thickness of 75 μm, dried at 60° C., and pressed with an ethylene-vinyl acetate copolymer film (1:1). Take the siliconized release paper as the protective layer, coat the pressure-sensitive adhesive layer substra...
