The invention discloses a preparation method of a TiCN-doped wear-resistant tungsten-copper composite material, which specifically comprises the following steps: respectively weighing tungsten powder, copper powder, copper-plated tungsten powder, nickel powder and TiCN powder in proportion, then loading into a sealing tank for mechanical mixing to obtain composite powder with uniform components, and loading into a mold for hot pressed sintering to obtain the TiCN-doped wear-resistant tungsten-copper composite material. And cooling to room temperature, and taking out the mold to obtain the TiCN-doped wear-resistant tungsten-copper composite material. The tungsten powder, the nickel powder, the copper powder and the doped TiCN powder are subjected to hot pressed sintering to prepare the tungsten-copper alloy, TiCN hard particles are dispersed and distributed in a copper phase after sintering, the abrasion resistance of the tungsten-copper alloy can be remarkably improved, and the service life of the tungsten-co
