Embodiment 1
[0045] Preparation of hydrophobic odor-absorbing masterbatch: Weigh 60% of ABS and 40% of hydrophobic odor-absorbing agent, dry mix them in a high-speed mixer for 3-5 minutes, then melt-extrude them in a twin-screw extruder, and granulate. Aluminum foil is vacuum sealed and ready for use. The extrusion process is as follows: zone 1 200-210°C, zone 2 210-220°C, zone 3 210-220°C, zone 4 205-215°C; the residence time of the entire extrusion process is 1 -2 minutes, the pressure is 12-18MPa.
[0046] Preparation of low-odor ABS resin compound: dry-mix 100 parts of ABS, 1 part of hydrophobic odor-absorbing masterbatch, 0.2 part of antioxidant 1010 and 0.1 part of antioxidant 168 in a high-speed mixer for 3 to 5 minutes, and then Melting extrusion and granulation in the twin-screw extruder, the process is: 220-230℃ in the first zone, 230-240℃ in the second zone, 230-240℃ in the third zone, 215-225℃ in the fourth zone; the whole extrusion process The residence time is 1-2 minutes, a...
