Abstract

The invention discloses a novel high-stability transparent silver ion complex, and a preparation method and application thereof. The novel high-stability transparent silver ion complex comprises silver nitrate, a pyrrolidone compound and a solvent; the pyrrolidone compound can absorb ultraviolet light, so that a discoloration phenomenon caused by the fact that silver ions absorb the ultraviolet light to improve activity is avoided. The silver ion complex disclosed by the invention is good in water solubility, high in transparency, good in stability, high in compatibility, low in addition amount in daily chemical products, safe and mild to use, and capable of enabling daily chemical products to have good antibacterial and bacteriostatic stability.

Description

technical field [0001] The invention relates to the technical field of antibacterial and disinfection, in particular to a novel high-stability transparent silver ion complex and its preparation method and application. Background technique [0002] Antibacterial agents are compounds with bactericidal and antibacterial functions. Silver ion antibacterial agents are metal ions with strong bactericidal and antibacterial power at present, and have the advantages of heat resistance, persistence, continuity and safety. However, silver ion antibacterial products currently on the market have some disadvantages, such as poor light stability, easy discoloration, poor compatibility, intolerance to chloride ions, and easy precipitation, which greatly reduce their application range. Therefore, it is of great significance to find silver ion complexes with high stability and good compatibility. [0003] There are 18 electrons in the outer layer of the silver element, and one electron in th...
