Heat vulcanizing silicone rubber premixing production line

The utility model discloses a heat vulcanizing silicone rubber premixing production line. According to the utility model, a raw rubber feed mechanism and a white carbon black feed mechanism respectively feed raw rubber and a white carbon black raw material into a first premixing machine, and materials are preliminarily premixed in the first premixing machine, then enter a second premixing machine to be premixed again, and enter a screw extruder finally to be mixed and dispersed. Compared with the prior art, the heat vulcanizing silicone rubber premixing production line provided by the utility model can produce heat vulcanizing silicone rubber with high performance, not only product stability and quality are improved, but also the production energy consumption is greatly reduced; and moreover, the phenomenon that low-molecular volatile substances are exploded can be avoided, so the safety production is ensured.
