The invention relates to a modified polyethylene wear-resistant composite pipe wound by multiple layers of steel wires. According to the preparation method disclosed by the invention, the beta-eucryptite is subjected to self-polymerization coating by utilizing dopamine under an alkaline condition, so that polydopamine is accumulated on the surface of the beta-eucryptite, and then modified nano silicon dioxide is obtained by matching with a silane coupling agent and silicon dioxide through reaction of silicon hydroxyl and alkoxy; the beta-eucryptite and the silicon dioxide cooperate to blend and modify the ultra-high molecular weight polyethylene to prepare the modified polyethylene, so that when the modified polyethylene is used as the material of the inner-layer pipe, on one hand, the beta-eucryptite and the silicon dioxide are added, so that the hardness and the wear resistance can be improved, and the silicon dioxide has very good heat conduction capability, so that heat dispersion of a friction surface ca
