Silver-containing antibacterial agent

Abstract

The invention relates to a silver-containing antibacterial agent, especially an antibacterial agent used for antibiotic fiber processing. It comprises soluble argentic salt and quaternary ammonium salt, the silver content is high and the antibiotic ability is strong. The color change during argentic salt utilization can be avoided because of the composite antibiotic function of silver ion and quaternary ammonium salt and the property of strong association with fiber. The antibacterial agent is characterized by simple and easy preparation and process, low cost, short production cycle and feasibility of large- scale production.

Description

technical field [0001] The invention relates to a silver-containing antibacterial agent. Background technique [0002] Antibacterial materials refer to a new class of functional materials that have the function of killing or inhibiting the growth of microorganisms. There are many substances in nature that have good functions of sterilizing and inhibiting the growth of microorganisms, such as some organic antibacterial agents with specific groups, some Inorganic metal materials and their antimicrobial agents, some minerals and natural substances. But at present, antibacterial materials refer to a new class of functional materials that can inhibit or kill bacteria on the surface of materials by adding certain antibacterial substances (called antibacterial agents). Antibacterial plastics, antibacterial fibers, and antibacterial ceramics have all appeared on the market and are used in various fields. [0003] At present, antibacterial agents are basically divided into four cat...

Problems solved by technology

Silver-based antibacterial materials currently have soluble silver salts, such as silver nitrate aqueous solution, which are used for eye disinfection of newborns, and are also used to treat oral ulcers, but soluble silver salts are easy to lose and cannot produce long-term antibacterial effects; slightly soluble or poorly soluble Silver salts such as silver sulfate, silver phosphate, silver halide, silver organic acid, etc., such slightly soluble or insoluble silver salts are easy to change color when exposed to light, and their application is greatly limited; silver ion antibacterial agents, such antibacterial agents have silver Ionic hydroxyapatite, silver-loaded montmorillonite, silver-loaded phosphate, silver-loaded medical stone, silver-loaded oxides such as silver-loaded silicon dioxide, silver-loaded titanium dioxide, etc., such antibacterial silver The content is low, the preparation process is complicated, and the cost is high. It is difficult to process when it is applied to fiber products, especially natural fibers. Amino acid silver, this type of antibacterial agent is also easy to change color, and is generally used in medicine; nano silver and nano silver antibacterial agent, this type of antibacterial agent is prepared by chemical reaction of silver ions into nano-scale silver particles or adsorbed on the carrier Nano-scale silver simple substance, this kind of antibacterial agent is generally colored because it uses nano-silver, and the scope of use is limited
