Embodiment 1
[0047] Example 1 Preparation of glass fiber reinforced polycarbonate resin of the present invention (1)
[0048] (1) Weigh each raw material according to the following weight ratio: 43 parts of PC-300-15, 7 parts of toughening agent EXL2678, 50 parts of glass fiber CSG 3PA-830, 0.1 part of antioxidant 1010, 0.2 part of antioxidant 168 , 0.2 parts of internal lubricant PETS;
[0049] (2) Mix the above raw materials (excluding glass fiber) in a medium-speed mixer for 20 minutes;
[0050] (3) Put the above-mentioned mixed raw materials into a twin-screw extruder with a melting temperature of 200-280°C, side-feed the glass fiber, melt extrude, and granulate. The temperature of each zone of the twin-screw extruder is: 1 The temperature in Zone 2 is 200-280°C, the temperature in Zone 3-4 is 200-280°C, the temperature in Zone 5-6 is 200-280°C, and the temperature in Zone 7-8 is 200-280°C. Control the temperature in Zone 9-10 to be 200-280°C.
Embodiment 2
[0051] Example 2 Preparation of glass fiber reinforced polycarbonate resin of the present invention (2)
[0052] (1) Weigh each raw material according to the following weight ratio: 77 parts of PC-300-15, 3 parts of toughening agent EXL2678, 20 parts of glass fiber CSG 3PA-830, 0.1 part of antioxidant 1010, 0.2 part of antioxidant 168 , 0.2 parts of internal lubricant PETS;
[0053] (2) Mix the above raw materials (excluding glass fiber) in a medium-speed mixer for 20 minutes;
[0054] (3) Put the above-mentioned mixed raw materials into a twin-screw extruder with a melting temperature of 200-280°C, side-feed the glass fiber, melt extrude, and granulate. The temperature of each zone of the twin-screw extruder is: 1 The temperature in Zone 2 is 200-280°C, the temperature in Zone 3-4 is 200-280°C, the temperature in Zone 5-6 is 200-280°C, and the temperature in Zone 7-8 is 200-280°C. Control the temperature in Zone 9-10 to be 200-280°C.
Embodiment 3
[0055] Example 3 Preparation of glass fiber reinforced polycarbonate resin of the present invention (3)
[0056] (1) Weigh each raw material according to the following weight ratio: 60 parts of polyethylene carbonate (weight average molecular weight 18000), 5 parts of toughening agent EXL2678, 35 parts of glass fiber (width-to-diameter ratio 2:1, length 6mm) , 0.5 part of antioxidant 1010, 0.5 part of antioxidant 168, 0.5 part of internal lubricant PETS, 0.5 part of release agent polyethylene wax;
[0057] (2) Mix the above raw materials (excluding glass fiber) in a medium speed mixer for 10 minutes;
[0058] (3) Put the above-mentioned mixed raw materials into a twin-screw extruder with a melting temperature of 200-280°C, side-feed the glass fiber, melt extrude, and granulate. The temperature of each zone of the twin-screw extruder is: 1 The temperature in Zone 2 is 200-280°C, the temperature in Zone 3-4 is 200-280°C, the temperature in Zone 5-6 is 200-280°C, and the tempe...
