The method comprises the following steps: cleaning a silver oxide / silver composite tape and a copper tape, feeding the silver oxide / silver composite tape and the copper tape to a high-frequency induction furnace for heating, and controlling the heating temperature in the high-frequency induction furnace to be 500-750 DEG C; feeding the silver oxide / silver composite tape and the copper tape to a tube-type resistance furnace for heating, wherein the length of a heating zone in the tube-type resistance furnace is 0.8-1.5m; controlling the heating temperature in the tube-type resistance furnace to be 600-850 DEG C; feeing the silver oxide / silver composite tape and the copper tape to a roller for hot-rolling compounding to obtain the silver oxide / silver / copper three-layer composite tape; and carrying out cold rolling and finishing rolling on the obtained three-layer composite tape according to a conventional process, wherein the heating process in the tube-type resistance furnace and the process from the heating process to the process of feeding the tapes to the roller are carried out in a reducing protective atmosphere. The technology disclosed by the invention can quickly warm, is stable and controllable in temperature, can solve the problem of reducing atmosphere protection during heating, and effectively avoids a poor oxide zone.
