Example Embodiment
[0029] Example 1
[0030] Weigh raw materials by weight percentage: PC resin 98.8%, dispersant 0.2%, hydrolysis-resistant agent AH210 0.1%, antioxidant 1076 0.3%, antioxidant 168 0.2%, lubricant EBS 0.4%.
[0031] Dry the PC resin in a blower dryer at a temperature of 110°C-130°C for 3-5 hours, add a dispersant and mix at high speed for 10 minutes, stop stirring, cool until the temperature drops to 30-35°C, and then add hydrolysis-resistant Agent, also mix at high speed for 10 minutes, then add antioxidant and processing aids and mix evenly at high speed. Through twin-screw extrusion and granulation, it can be cooled and granulated.
[0032] The granulator is a 35# twin-screw extruder, and the process parameters are: the temperature of the first zone is 130°C, the temperature of the second zone is 230°C, the temperature of the third zone is 235°C, the temperature of the fourth zone is 240°C, the temperature of the fifth zone is 240°C, and the temperature of the sixth zone is ...
