Embodiment 1
[0027] Example 1: Preparation of polypropylene composite material for water purifier filter bottle shell
[0028] Weigh the corresponding raw materials according to the above weight parts: see Table 1
[0029] After that, the homopolypropylene, copolymer polypropylene, Vistamaxx elastomers, fillers, antioxidants, lubricants, antibacterial agents, nucleating agents, and titanium dioxide weighed in proportion are mixed uniformly from the main feed The port is added to the parallel twin-screw extruder, so that all the component materials are sheared, melt-blended and extruded in the parallel twin-screw extruder. The processing temperature of the twin-screw extruder is 180°C in the first zone and 190°C in the second zone. , Three-zone 200℃, four-zone 220℃, five-zone 220℃, six-zone 215℃, seven-zone 215℃, eight-zone 215℃, nine-zone 210℃, ten-zone 210℃, machine head 220℃;
[0030] Finally, the material strips exiting the die of the parallel twin-screw extruder are cooled, dried, and pellet...
