Abstract
The invention discloses a rubber granulation process which comprises the following steps: (1) carrying out thin-passing and plastication on rubber with different process performances on an open mill until the degree of plasticity is more than 0.45; (2) putting the plasticated rubber into an internal mixer for mixing; (3) adding fine stuff, carbon black and oil, which are prepared according to a formula, into the mixed rubber material in the step (2), and mixing in the internal mixer; (4) thin-passing, cooling and stacking the mixed rubber material; (5) weighing the cooled rubber material according to the formula, and adding sulfur on the open mill; after uniformly stirring, hitting three triangles, and hitting three transverses; (6) sending the sulfurated rubber material into an extruder to be extruded, and granulating on a water cutting machine; (7) after drying and dewatering the cut rubber particles, screening and filtering through a cooling vibrating screen. The rubber particles produced by the process overcome the defect that the vulcanized rubber produced by the traditional process cannot be placed for a long time, and have a wide market prospect.
