The invention discloses a high-strength isolation structure UHMWPE/PP/superconducting carbon black conductive composite material and a preparation method thereof. The material is prepared from, by weight, 84-98.7 parts of UHMWPE powder, 2-5 parts of PP powder, 0.1-10 parts of superconducting carbon black, 0.1-0.5 part of an antioxidant and 0.1-0.5 part of a cross-linking agent. The preparation method comprises the steps of (1) drying of raw materials; (2) preparation of UHMWPE/PP/superconducting carbon black blending particles by high-speed mixing; (3) high-temperature pressing forming. The high-strength isolation structure UHMWPE/PP/superconducting carbon black conductive composite material has a low percolation threshold when the superconducting carbon black is added in an amount of 0.5wt% and the electrical conductivity is close to 10-6 S/cm, has higher tensile strength and toughness, and not only has the excellent mechanical properties comparable to ultra-high molecular weight polyethylene, but also gives a UHMWPE / PP alloy a novel special function.
