The invention solves the anti-discoloration ability of conventional silver ion antibacterial agents through the preparation of complexes Poor, poor antibacterial durability and poor salt resistance, successfully realized the application of the prepared antibacterial agent in light-colored products, in alkaline environments, and in products or environments containing chloride ions, expanding the application range of antibacterial agents, And ensure the application effect of antibacterial agent.

Description

Technical field: [0001] The invention relates to the technical field of inorganic-organic composite antibacterial agents, in particular to a preparation process of an inorganic-organic composite antibacterial agent. Background technique: [0002] Antibacterial agents are a class of agents that can kill or inhibit harmful microorganisms such as bacteria and viruses, mainly including organic antibacterial agents and inorganic antibacterial agents. Compared with organic antibacterial agents, inorganic antibacterial agents have the characteristics of good safety, high thermal decomposition temperature, good stability, strong antibacterial properties, and long-lasting antibacterial properties. Inorganic antibacterial agents are usually composed of antibacterial components and carriers, and metal or metal ions with antibacterial ability are fixed on the carrier by physical adsorption or ion exchange. The metal ions with antibacterial activity include silver, zinc, iron, aluminum,...
