[0079] The present invention will be further explained below in conjunction with the drawings:
[0080] figure 1 Shown is the working state diagram of the twin-screw extruder. The positions of each part should be correct, proportioning according to the quantity, and operation in order.
[0081] The amount of chemical materials used in the preparation is determined according to a preset range, with grams, milliliters, and centimeters as the unit of measurement.
[0082] The preparation of silica + polyphenylene sulfide masterbatch is carried out on a twin-screw extruder, which is completed under heating, electric metering feeding, twin-screw extrusion, water cooling, and pelletizing by a pelletizer; The twin screw 15 is placed on the upper part of the base 25 of the extruder 26. The twin screw 15 is engaged with left and right, and the two screws are engaged with the right rotation. On the left of the twin screw 15 is the screw motor 14; Main feed box 10 and side feed box 11, main fe...
