A leather finishing agent that can enhance the mechanical properties and ultraviolet resistance of leather and a preparation method thereof are disclosed that relate to the field of leather additives. It was prepared by using polyphenol as raw material, hexamethylene tetramine as auxiliary agent, and a protonic acid as solvent, then heating and adding water for hydrolysis and dispersion. The method has the advantages of low production cost, simple process, high preparation efficiency, green production process and environmental protection. The leather finishing agent can be used in the finishing section after leather tanning. After finishing, the mechanical properties of the leather were significantly enhanced, and its UV resistance was also significantly improved.
