Abstract

PURPOSE:To uniformly knead main extrudate and additives in a screw extruder which merges and mixes additives, by connecting an additive supply part and a screw having a lead hole for additives by means of a rotary joint and providing additive discharge holes to the screw surface. CONSTITUTION:Tips of a thermoplastic polymer are charged from the hopper 2 of an extruder consisting of a cylinder 4 provided with a screw 5 for mixed extrusion. They are heated to melt by heaters 3 and the polymer is extruded forward by the revolution of the screw 5. At this time, additives of viscosities much lower than that of the polymer are supplied into the additive lead hole 11 provided in the screw 5 by way of a rotary joint 8, and are discharged through the discharge hole 12 opened in the front of a flight 10 and the discharge hole 13 opened in the channel surface, whereby they are kneaded into the thermoplastic polymer which is a main extrudate. Both are perfectly mixed and are discharged from a passage 7 through a breaker plate 6.
