The present invention relates to a process for manufacturing an ultra-high thermally conductive graphene curing bladder, including the following steps: (1) pre-mixing an ultra-high thermally conductive graphene with rubber to obtain a pre-dispersed graphene master batch, performing a granulation process or a cutting process on the pre-dispersed graphene master batch to obtain a granular solid or a sheet solid, mixing the solid in a rubber mixing mill to obtain an ultra-high thermally conductive graphene rubber compound; (2) extruding, by an extruding machine, the ultra-high thermally conductive graphene rubber compound into a rubber strip of a desirable size; weighing and fixed-length processing the rubber strip of the ultra-high thermally conductive graphene rubber compound to obtain a rubber blank, placing the rubber blank into a pressing type curing bladder mold, closing the mold, pressurizing, heating and curing to obtain a finished product of the ultra-high thermally conductive graphene curing bladder. The present invention has the advantages of greatly improving the thermal conductivity of the curing bladder and accelerating the heat transfer, so that the vulcanization efficiency of products is improved.
