▎ 摘  要

NOVELTY - Supported catalyst comprises carrier and active component; the carrier is ferric trichloride modified graphite, active component is titanium tetrachloride or titanium trichloride; where, the titanium content in the supported catalyst is 0.2-6 wt.%, based on total mass of supported catalyst. USE - The supported catalyst is useful for preparing conductive polyolefin composite material used for conductive, anti-static, electromagnetic shielding and other product. ADVANTAGE - The conductive polyolefin composite material: has low content of conductive filler, and has good electrical conductivity; and maintains performance of polyolefin resin materials. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing the supported catalyst comprising providing ferric trichloride modified graphite, and reacting titanium tetrachloride or titanium trichloride with ferric trichloride modified graphite under inert atmosphere, to obtain the supported catalyst; and (2) preparing conductive polyolefin composite material comprising subjecting olefin to slurry polymerization in presence of supported catalyst and cocatalyst, to obtain conductive polyolefin composite material precursor, adding conductive carbon material to the conductive polyolefin composite material precursor, and grinding to obtain the conductive polyolefin composite material.
