The invention belongs to the technical field of cross-linking agent preparation, and provides a titanium-zirconium cross-linking agent and a preparation method thereof. The titanium-zirconium cross-linking agent provided by the invention is prepared from the following raw materials: inorganic titanium, a ligand, inorganic zirconium, protonic acid and water, the inorganic titanium comprises titanium phosphate and/or titanium sulfate; the ligand comprises one or more of diethanol amine, triethanolamine, ammonium citrate and sodium gluconate; the inorganic zirconium comprises zirconium oxychloride and/or zirconium sulfate. According to the titanium-zirconium cross-linking agent, the titanium cross-linking agent and the zirconium cross-linking agent are introduced at the same time, so that the titanium-zirconium cross-linking agent has the advantages of the titanium cross-linking agent and the zirconium cross-linking agent at the same time, and the pH application range of the titanium-zirconium cross-linking agen
