This invention pertains to a low-cost, high-efficiency method for continuously producing high-performance recycled rubber within the field of waste rubber recycling.
Two tandem twin-screw extruders perform deep desulfurization and mixing reactions. In the first extruder, waste rubber undergoes high shear and temperature to form a fluid rubber mixture rich in light oils, gases, and high fluidity.
This mixture is fed into the second twin-screw extruder, where a portion of the fluid rubber mixture rapidly permeates into the rubber powder interior.
This achieves efficient heat utilization while enabling rapid desulfurization and regeneration reactions.
The entire preparation process occurs under sealed, oxygen-free conditions, yielding regenerated rubber with excellent properties.
The primary equipment used is a two-stage twin-screw extruder, offering advantages of safe, simple, continuous operation, energy efficiency, and environmental friendliness.
