Abstract

The invention is a preparation method of a layered unsaturated loaded silver-zinc-copper composite antibacterial and antiviral material. Weighing silver salt, zinc salt, copper salt, modifier, complexing agent and solvent, using ultrasonic-assisted high-speed shear stirring to modify and complex metal ions to prepare metastable complex silver-zinc-copper composite ions; Then stir and disperse, adsorb into the interlayer of the two-dimensional nano-layered material through unsaturated adsorption, and then add the supercritical reactor, and press the carbon dioxide into the reactor by the high-pressure pump; control the pressure and temperature, and quickly release the supercritical fluid through the nozzle. After pressing, centrifuging, drying and pulverizing, a layered unsaturated silver-zinc-copper composite antibacterial and antiviral material is obtained. The composite antibacterial and antiviral material prepared by the invention has the advantages of good heat resistance and high safety, can be used to prepare fibers such as antibacterial and antiviral polyester, nylon, etc., which can be mixed with Tencel, combed cotton, etc., and can be widely used in underwear, In sports jackets, home textiles and other fields, the fabrics are comfortable to the touch and have strong antibacterial and antiviral functions.

Description

technical field [0001] The invention belongs to the field of nanometer preparation, and in particular relates to a preparation method of a layered material unsaturated supporting silver-zinc-copper composite antibacterial and antiviral. Background technique [0002] With the development of modern society, people's requirements for the quality of life are getting higher and higher, which has also led to the concern of the masses of bacteria and viruses that are ubiquitous in life. Especially in the context of the 2020 new crown pneumonia raging around the world, people's demand for antibacterial and antiviral is growing. In daily life, in addition to the new coronavirus, bacterial viruses such as influenza virus, Escherichia coli, and Staphylococcus aureus also pose a huge threat to people's lives and health. Antiviral materials became an urgent problem for cash. [0003] At present, the commonly used antibacterial materials include inorganic antibacterial materials and org...
