The mixing of kind.
The lubricant is one of zinc stearate, calcium stearate or potassium stearate or a variety of.
A kind of preparation method of PPS composite material, comprising the following steps:
1) it is micro- that 80 parts -100 parts of PPS, 5 parts -10 parts of ASA, 10 parts of -20 parts of calcium sulfate crystal whiskers, 8 parts of -12 parts of carbon are weighed
Ball, 0.1 part of -0.5 part of antioxidant, 0.1 part of -0.3 part of mix lubricant simultaneously stir evenly, and obtain mixture；
2) mixture obtained in step 1) is added from owner's feeder is squeezed out, 12 parts of -18 parts of carbon fibers are by side feed material
Device is individually added into extruding pelletization to get PPS composite material is arrived.
The step 2) specifically: extruder is double screw extruder, and the double screw extruder includes sequentially arranging
