Abstract

The invention provides a rare-earth antifungal agent composition. A certain amount of nano titanium dioxide silver antifungal agent is dispersed in ethyl alcohol, bis(pentamethylcyclopentadienyl)cobalt, cyclopentadienylrhenium tricarbonyl, benzoyl peroxide, polyvinyl alcohol and sodium dodecyl benzene sulfonate are added according to the proportions, and a nano titanium dioxide silver antifungal agent micro suspension product containing rare earth is obtained through surface polymerization.

Description

technical field [0001] The invention relates to a preparation method of an antibacterial agent, in particular to a rare earth antibacterial agent composition. Background technique [0002] Rare earth elements and their compounds have good anti-inflammatory, bactericidal, anti-cancer, anti-coagulation, and analgesic effects. Heterocyclic compounds are a class of compounds with a wide range of biological activities. Many heterocyclic compounds have biological activities such as sterilization, anti-inflammation, and anti-virus, so they have attracted much attention. After the heterocyclic compound forms a complex with metal ions, the antibacterial effect of the metal complex will be enhanced due to the synergistic effect. Relevant studies have shown that compared with many organic synthetic drugs, rare earth complexes have lower toxicity, and at the same time, no accumulation in the body has been found through oral or external use of rare earth complexes, so they have wider ap...
