The invention discloses an iron-based catalytic butadiene-isoprene rubber tire tread composite material with high isoprene monomer content and a preparation method of the iron-based catalytic butadiene-isoprene rubber tire tread composite material, and belongs to the technical field of rubber materials and preparation of the rubber materials. The composite material is prepared from olefin rubber, reinforcing filler, a silane coupling agent, zinc oxide, stearic acid, sulfur, an anti-aging agent and an accelerant, wherein the olefin rubber is prepared by mixing natural rubber, solution polymerized styrene-butadiene rubber, butadiene rubber and iron-based catalytic butadiene-isoprene rubber. The invention aims to provide a novel composite rubber with high wet skid resistance and a preparation method under the conditions of keeping low rolling resistance and high wear resistance by increasing the content of isoprene monomers for synthesizing iron-based catalyzed butadiene-isoprene rubber and further increasing the content of propenyl side groups in the iron-based catalyzed butadiene-isoprene rubber and further increasing the content of propenyl side groups in the iron-based catalyzed butadiene-isoprene rubber.
