Example Embodiment
[0053] Example 1
[0054] First, take PC / ABS secondary materials, PC secondary materials, compatibilizers, toughening agents, brominated small molecule flame retardants, antimony flame retardants, antioxidants, ultraviolet absorbers and other ingredients, and press parts by weight The following composition formula blends all raw materials:
[0055] PC / ABS secondary material 81;
[0056] PC secondary material 5;
[0057] SMA 2;
[0058] MBS 5;
[0059] Decabromodiphenylethane 5;
[0060] Sb 2 O 3 2;
[0061] Antioxidant 0.3;
[0062]UV absorber 0.3.
[0063] Secondly, the above blended material is mixed and pelletized in an extruder;
[0064] Thirdly, the obtained mixing granulation can be made into finished products after modification of the secondary materials after injection molding.
[0065] The modified finished product was tested for performance and compared with the performance of the PC / ABS raw material alloy. The test results are shown in Table ...
