Wear-resistant antibacterial coating for bathroom hardware and preparation method of wear-resistant antibacterial coating

The invention relates to a preparation method of a wear-resistant antibacterial coating for bathroom hardware. The preparation method comprises the following steps: S1, providing a pretreated bathroom hardware base material; s2, carrying out substitution reaction on dipyridyl dibasic acid and alkyl bromide under the protection of inert gas, and carrying out anion exchange on a reaction product and sodium tetrafluoroborate to obtain an MOF organic ligand; s3, dispersing the metal particles in a solvent compounded with antibacterial metal ions, adding an MOF organic ligand, and performing hydrothermal reaction to obtain a composite material with the metal particles coated with a metal organic framework material; and S4, dispersing in a solvent, and carrying out electrochemical deposition reaction under constant voltage by taking the bathroom hardware base material as a working electrode and a platinum sheet as a counter electrode to form a layer of wear-resistant antibacterial coating.
