[0002] At present, the PC black masterbatches on the market are mainly general-purpose PE carrier black masterbatches and PC carrier black masterbatches. The former is poorly compatible with PC materials, and its impact strength drops rapidly, resulting in brittle products.
The latter has good compatibility with PC materials and can keep the physical properties of PC materials to a greater extent. Chinese invention patent (CN104761858B) discloses a solid-color PC masterbatch with a toughening effect. Although the masterbatch It has good impact resistance, but the products produced by it have poor electrostatic adsorption effect and do not have permanent semi-conductive function

Abstract
The invention belongs to the technical field of high polymer materials, and particularly relates to a semi-conductive PC black master batch and a preparation method thereof. The semiconductive PC black master batch is prepared from the following raw materials in percentage by weight: 30-60% of PC, 5-10% of an impact modifier, 15-30% of conductive carbon black, 5-15% of a colorant, 1-10% of a dispersant, and 0.5-5% of a processing aid. The PC color master batch which is high in blackness, good in toughness, capable of eliminating static electricity and permanently semi-conductive and capable ofkeeping physical properties of a PC material to the maximum extent is finally prepared by compounding a dispersing agent, adding a processing aid, a color master carrier, an impact modifier, conductive carbon black and a coloring agent and processing by a specific processing method.
