[0013] According to the drawings, the selection of the process circuit of the present invention:
[0014] In today's world, there are mainly internal mixer method, reactor method and extruder granulation method for manufacturing plastic masterbatch. According to the actual situation in China, the twin-screw extruder granulation method is selected in the present invention. Its advantages are: easy processing, convenient management, high production efficiency, and no pollution to the environment.
[0015] The process conditions of the filling masterbatch for the plastic film of the present invention:
[0016] 1. Stirring mixer: heating range 0~200℃;
[0017] 2. Co-rotating twin-screw granulator; Specification: φ75×36D
[0018] 1 heating
[0019] Screw speed: 5~120 revolutions / min; Pelletizer speed: 30~60 revolutions / min; Air-cooled eager cutting: It can be eagerly cut on the die surface, or drag chain eagerly, not water-cooled.
