The invention relates to a high-performance PE composite material. The high-performance PE composite material consists of the following components in parts by weight: 50 to 70 parts of PE, 5 to 10 parts of polyurethane, 20 to 30 parts of modified nano ZrO2, 0.4 to 0.6 part of polyethylene wax grafted maleic anhydride, 0.1 to 0.5 part of antioxidant, and 0.1 to 0.3 part of lubricating agent. According to the technical scheme, the silane coupling agent KH550 is added into nano zirconium dioxide, not only can the nano zirconium dioxide be effectively modified, but also the silane coupling agent KH550 can have interaction with the grafted maleic anhydride, so that the interaction between the nano zirconium dioxide and polyethylene wax can be improved, the compatibility of the PE and nano zirconium dioxide can be improved, the dispersity can be improved, the adhesion can be improved, and the physical properties of the PE composite material can be improved.
