The antistatic master granule the preparation method comprises the following steps:
1) a certain amount of PEEA, EPDM-g-MAH and PS are weighed；
2) material each in step 1) investment high-speed mixer is mixed, it is to be mixed uniform, it is put into double screw extruder and squeezes
It is granulated out, drying both obtains antistatic master granule.
The mass ratio of PEEA, EPDM-g-MAH and PS in step 1) are (2-6): (20-30): (200-400).
High-speed mixer revolving speed described in step 2) is 280~320r/min, and the double screw extruder includes suitable
Six humidity provinces of secondary arrangement, 160~180 DEG C of area's temperature, two 180~220 DEG C of area's temperature, three 180~220 DEG C of area's temperature,
Four 180~220 DEG C of area's temperature, five 180~220 DEG C of area's temperature, six 180~220 DEG C of area's temperature, 180~220 DEG C of head temperature；
180~260r/min of screw speed.
The antioxidant is three (2,4- di-t-butyl) phenyl-phosphites, four [β-(3,5- di-tert-butyl-hydroxy phenyl)
Propionic acid] pentaerythritol ester or 1,3,5- trimethyls -2,4, one of 6- (3,5- di-t-butyl -4- hydroxyphenylmethyl) benzene or several
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 PS composite material, comprising the following steps:
1) weigh 80 parts -100 parts of PS, 3 parts -5 parts of PTFE, 10 parts of -16 parts of antistatic master granules, 0.1 part -0.5 part it is anti-
Oxygen agent, 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, 20 parts of -30 parts of PPTA fibers are by side feed
Glassware is individually added into extruding pelletization to get PS composite material is arrived.
Preferably, the step 2) specifically:
Mixture obtained in step 1) is put into extruding pelletization in the hopper of double screw extruder, wherein described double
Screw extruder includes six humidity provinces sequentially arranged, 160~180 DEG C of area's temperature, two 210~230 DEG C of area's temperature, 3rd area
210~230 DEG C of temperature, four 210~230 DEG C of area's temperature, five 210~230 DEG C of area's temperature, six 210~230 DEG C of area's temperature, head
210~230 DEG C of temperature, 200~280r/min of screw speed.
The beneficial effects of the present invention are:
There are three effects for PPTA fiber in the application: 1) it can be built into " network ", antistatic master granule and " network "
It is readily formed conductive network, further strengthens the antistatic property of PS composite material.2) it can promote PS composite material
Tensile strength, bending strength, impact strength.3) PPTA fiber itself has certain anti-flammability, its addition improves PS
The flame retardant property of composite material.
