Embodiment I
[0040] The raw materials are weighed according to the following percentage by weight:
[0041]
[0042]
[0043] (1) Weigh 25% of R-105 according to the weight ratio and put it into the stirring dryer. The temperature of the stirring dryer is set at 80°C. After stirring and drying for 2 minutes, add 4% polyzincamide, and then mix 5 minutes; then add 20% PPO LXR045, 25% PA66 EPR2.7, 4% FG1901, 5% G1651, 0.6% 1098 and mix for 3 minutes, discharge the material, add it from the main feeding port of the twin-screw extruder after cooling;
[0044] (2) Weigh 8% RDP and 8.4% PB680 according to the weight ratio and mix them in proportion, then add them from the fourth section of the twin-screw extruder through the feeding pump.
[0045] (3) After extruding and granulating through a twin-screw extruder, the rotating speed of the screw machine is 180 rpm, and the temperature is 235°C.
Embodiment 2
[0047] The raw materials are weighed according to the following percentage by weight:
[0048]
[0049](1) Weigh 12.5% R-105 according to the weight ratio and put it into the stirring dryer. The temperature of the stirring dryer is set at 80°C. After stirring and drying for 5 minutes, add 1% polyzincamide, and then mix 2 Minutes; then add 50% PPO LXR045, 20% PA6 1013B, 4% FG1901, 2% G1701, 0.5% 1098 and mix for 5 minutes, discharge the material, add it from the main feeding port of the twin-screw extruder after cooling;
[0050] (2) Weigh 5% RDP and 5% PB680 according to the weight ratio and mix them in proportion, then add them from the fourth barrel of the twin-screw extruder through the feeding pump.
[0051] (3) After extruding and granulating through a twin-screw extruder, the rotating speed of the screw machine is 600 rpm, and the temperature is 275°C.
Embodiment 3
[0053] The raw materials are weighed according to the following percentage by weight:
[0054]
[0055] (1) Weigh 10% R-105 according to the weight ratio and put it into the stirring dryer. The temperature of the stirring dryer is set at 100°C. After stirring and drying for 5 minutes, add 2% polyzincamide, and then mix 3 Minutes; then add 20% PPO LXR045, 50% PA6 1013B, 2% FG1901, 3.8% G1651, 0.2% 1098 and mix for 4 minutes, discharge the material, add it from the main feeding port of the twin-screw extruder after cooling;
[0056] (2) Weigh 10% RDP and 2% PB680 according to the weight ratio and mix them in proportion, then add them from the fourth section of the twin-screw extruder through the feeding pump.
[0057] (3) After extruding and granulating through a twin-screw extruder, the rotating speed of the screw machine is 400 rpm, and the temperature is 245°C.
