Embodiment 1
[0014] Weigh 600 grams of ABS and dry at 90°C for 4 hours, then mix with 80 grams of starch, 130 grams of polyethylene, 50 grams of γ-aminopropyltriethoxysilane, methyl methacrylate-butadiene-styrene 50 grams of copolymer and 8 grams of monoglyceride stearate were stirred for 5 minutes at 1100 rpm in a high-speed mixer, and released after being uniform. Put the mixed material into the twin-screw extruder with a length-to-diameter ratio (L / D) of 40. The processing temperature of the twin-screw extruder: the temperature in the first zone is 180°C, the temperature in the second zone is 185°C, and the temperature in the third zone is 180°C. The temperature of the fourth zone is 195°C, the temperature of the fourth zone is 210°C, the temperature of the fifth zone is 215°C, the temperature of the sixth zone is 225°C, the temperature of the seventh zone is 235°C, the temperature of the eighth zone is 240°C, and the speed of the main engine is 320 rpm; After cooling the stays, air-dry...
