Abstract: A process for manufacturing an ultra-high thermally conductive graphene curing bladder includes 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.
