The invention discloses a rubber waterstop low-temperature one-time rubber refining production line. The production line comprises an internal mixer upper auxiliary machine, an internal mixer, a twin-screw extrusion tablet press, a rubber master batch cooling line system, a rubber turnover mixing system, a tablet press and an annular rubber sheet cooling line which are connected with a control system, wherein the internal mixer upper auxiliary machine and the internal mixer are connected; the internal mixer upper auxiliary machine is used for conveying materials to the internal mixer; the internal mixer is used for mixing virgin rubber, powder and an oil auxiliary; the twin-screw extrusion tablet press and the rubber master batch cooling line system are connected; the twin-screw extrusiontablet press communicates with a discharge port of the internal mixer and used for extruding rubber sheets; the rubber master batch cooling line system is used for cooling the rubber sheets; the rubber turnover mixing system, the tablet press and the annular rubber sheet cooling line are connected; the rubber turnover mixing system communicates with a discharge port of the rubber master batch cooling line system; the rubber sheet is supplemented through the rubber turnover mixing system for mixing, pressed through the tablet press and cooled through the annular rubber sheet cooling line. The rubber waterstop low-temperature one-time rubber refining production line improves the dispersity of rubber waterstop carbon black and various compounding agents to prevent rubber from generating carbon black gel, the breaking strength, wear resistance and fatigue resistance of the rubber and the productivity of the production line are improved, and energy consumption is reduced.
