Embodiment P
[0029] see figure 1 , figure 1 Show the flow chart of the method for preparing the PC alloy material of the embodiment of the present invention, including the following steps:
[0030] Step S01, providing raw materials:
[0031]
[0032] Specifically, the above-mentioned PC, ASA, antioxidant, toughening agent, lubricant, flow promoter, etc. are the same as those described above, and will not be repeated here.
[0033] Step S02, preparing the first mixture:
[0034] Mixing the PC, ASA, antioxidant, toughening agent and lubricant to obtain a first mixture;
[0035] Specifically, in step S02, after drying PC and ASA, add them to the blender, then add antioxidant, toughening agent and lubricant, and stir evenly to obtain the first mixture;
[0036] Step S03, preparing the second mixture:
[0037] adding the flow enhancer to the first mixture, and mixing to obtain a second mixture;
[0038] Step S04, extrusion process:
[0039] Extruding the second mixture to obtain a PC ...
Embodiment PC
[0046] The preparation method of the PC alloy material of the embodiment of the present invention comprises the following steps:
[0047] Provide the following components in weight percentage:
[0048] PC 80%, ASA 8%, toughener 9%, lubricant 0.5%, antioxidant 0.5%, rheology control agent 2%%;
[0049] After drying PC and ASA, add them to the mixer, then add antioxidant, toughening agent and lubricant, and stir evenly to obtain the first mixture; add the flow enhancer to the first mixture, and mix to obtain the second mixture. Two mixtures;
[0050] The second mixture is put into a twin-screw machine and granulated by melt extrusion. The process is as follows: the temperature of the first stage of the twin-screw is 220-230°C, the temperature of the second stage is 240-250°C, the temperature of the third stage is 250-260°C, and the mold temperature is 60-260°C. 100°C, residence time 1-2 minutes, pressure 10-15MPa.
