Abstract

A nano-porous composite Ag-Zn particle material in the form of white or gray powder for adsorbing, suppressing and killing bacteria is prepared from the Ag salt, Zn salt and silicate based nano-porous material through thermodynamic ion exchange or ionic exchange in solution, drying and heat treating. It can be used for food, medicine, health-care product, cosmetics, etc.

Description

technical field [0001] The invention belongs to the field of new nanometer materials and applications thereof, in particular to a silver-zinc particle nanoporous composite material prepared from metal silver salts, zinc salts and silicate-based nanoporous materials and its application in the field of surface anti-infection. Background technique [0002] Bacteria and viruses have always accompanied the development of human society, but once they mutate and infect humans, they will greatly affect the normal economic life order and health of humans, such as: Neisseria gonorrhoeae (Neisseria gonorrhoeae), Vibrio cholerae (Vibrio cholerae) ), Mycobacterium tuberculosis, hepatitis B virus (HBV), human immunodeficiency virus (HIV), SARS virus, etc. It has been confirmed that Helicobacter pylori is closely related to the pathogenicity of peptic ulcer and gastric cancer. HIV causes acquired immunodeficiency syndrome (AIDS), which leads to the complete collapse of the body's immune sy...
