Examples
Embodiment 1
[0014] Carbon black 20%, HDPE 14%, transparent ABS 20%, PE wax 3%, EBS 3%, barium sulfate 40%. The components are added to a low-speed mixer, blended for 10 minutes, and the fully mixed materials are added to the twin-screw extruder to be extruded and granulated to prepare the color masterbatch.
Embodiment 2
[0016] Carbon black 30%, LLDPE20%, LDPE10%, PC20%, EVA wax 6%, SMA3%, magnesium stearate 2%, antioxidant 10106%, antioxidant 1683%. The components are added to a low-speed mixer and blended for 5 minutes. The fully mixed materials are added to a double-rotor continuous mixer for mixing, and then extruded and pelletized by a single-screw extruder to prepare a color masterbatch.
Embodiment 3
[0018] Carbon black 35%, oil-soluble black 5%, LLDPE10%, PMMA10%, SMA2%, ASA28%, ester wax 7%, oxidized PE wax 2%, antioxidant 10101%. Each component is directly put into the internal mixer for banburying for 15 minutes, and then extruded and granulated by the screw extruder to prepare the color masterbatch.
