Embodiment 1

[0160] Embodiment 1. Take A-type nanoporous material and silver nitrate and add them into the reaction container according to the mass ratio of 1:0.01-1:9, stir evenly under the condition of avoiding light, then transfer to the horse-width furnace at 100-600 degrees Celsius Heating and reacting in the range of 0.5-12 hours. After cooling, a white or light gray powder solid A-type silicate-based angstrom silver ion nanoporous composite material is obtained.

[0161] By changing the amount of silver nitrate, the unit cell composition can be obtained: Ag 12-X Na X [Al 12 Si 12 o 48 ] · 0~27Ag (X=0.1~1) series of A-type silicate-based Angstrom silver ion nanoporous composite materials. The color changes to light gray with increasing silver content.

Embodiment 2

[0162] Example 2. Except changing the A-type zeolite molecular sieve to X-type zeolite molecular sieve, the reaction step conditions were the same as in Example 1, and a series of white or light gray powder solid X-type silicate-based Angstrom silver ion nanoporous composite materials were obtained. The unit cell is: Ag 86-X Na X [Al 86 Si 106 o 384 ]·0~264Ag(X=0.1~86)

Embodiment 3

[0163] Embodiment 3, except changing A-type zeolite molecular sieve to Y-type zeolite molecular sieve, reaction step conditions are the same as embodiment 1, obtain a series of white or light gray powder solid Y-type silicate-based Angstrom silver ion nanoporous composite materials. The unit cell is: Ag 56-X Na X [Al 56 Si 136 o 384 ]·0~264Ag(X=0.1~55)

Abstract

A broad-spectrum antibacterial silicate-based angstrom Ag ion-nonoporous material able to kill more than 11 bacteria including ring worm, fungus, candida, blue mold, etc is prepared from the Ag ions and the silicate-base nanoporous material chosen from the molecular sieves of X-ray zeolite, A-type zeolite, Y-type zeolite, mordenite, etc.

Description

technical field [0001] The present invention belongs to a new application of silicate-based angstrom silver ion nanoporous composite material, and specifically relates to a silicate-based angstrom silver ion nanoporous material prepared from silicate-based nanoporous material and silver ions or nano-silver ions. Application of porous composite materials in antibacterial and bactericidal aspects. 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 pathogenesis of peptic ulcer and gastric cancer. HIV causes acquired immunodeficiency synd...
