  • Patent number: 11746231
    Abstract: A transparent static-dissipative polycarbonate (PC) resin composition includes the following components: 70-95 parts by weight of PC resin, 5-30 parts by weight of antistatic agent masterbatch and 0.5-1.5 parts by weight of a transesterification inhibitor. The antistatic agent masterbatch includes the following components by mass percentage: 40-60% of an antistatic agent, 0.5-1.6% of a transesterification accelerator, 1-3% of an assistant cross-linkinger, and the balance of PC resin. A method for preparing the transparent static-dissipative PC resin composition includes the following steps: (I) preparing the components of the transparent static-dissipative PC resin composition according to the formulation, and mixing the components evenly to obtain a premix; and (II) adding the premix into a twin-screw extruder, melting, extruding, cooling and pelletizing, to obtain a target product.
