Abstract

The invention provides silver-loaded zirconium phosphate as well as a preparation method and application thereof. The preparation method comprises the step of reacting a mixed solution containing a water-soluble silver salt, a reducing agent and zirconium phosphate to obtain the silver-loaded zirconium phosphate. According to the method, an in-situ reduction method is adopted, silver ions are directly subjected to a reduction reaction on the surface of zirconium phosphate and in mesopores through a reducing agent, and the silver-loaded zirconium phosphate is obtained. The silver-loaded zirconium phosphate provided by the invention has relatively high silver loading capacity and is suitable for being used as an antibacterial agent, and the preparation method provided by the invention is simple and easy to operate and mild in process conditions.

Description

technical field [0001] The invention belongs to the field of antibacterial agents, and in particular relates to a silver-loaded zirconium phosphate and a preparation method and application thereof. Background technique [0002] With the advancement of science and technology and the improvement of living standards, people pay more and more attention to the safety protection awareness of the living environment. Among them, clothing, home textiles and plastic daily necessities with antibacterial functions have attracted widespread attention. At present, there are three main types of antibacterial materials: natural antibacterial materials, organic antibacterial materials and inorganic antibacterial materials. Although natural antibacterial materials have good antibacterial effect and are less harmful to the environment and human body, they begin to carbonize and decompose at 150-180°C, and their application range is narrow; although organic antibacterial materials have strong b...
