Problems solved by technology

It has been confirmed that Helicobacter pylori is closely related to the pathogenesis of peptic ulcer and gastric cancer. HIV causes acquired immunodeficiency syndrome (AIDS), which leads to the complete collapse of the body's immune system, rapid spread, and mortality. High, there is still no satisfactory treatment

Embodiment 1

[0094] Embodiment 1, get A-type nanoporous material and silver nitrate by mass ratio of 1: 0.01-1: 9 and add it to the reaction vessel, stir evenly under light-proof conditions, and then transfer to a horse-width furnace at 100-600 degrees Celsius The heating reaction in the interval is 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.

[0095] By changing the amount of silver nitrate, the unit cell composition can be obtained as: Ag 12-X Na x [Al 12 Si 12 O 48 ]·0~27Ag (X=0.1~1) A series of A-type silicate-based Angstrom silver ion nanoporous composite materials. The color changes to light gray with increasing silver content.

Embodiment 2

[0096] Example 2, except that the A-type zeolite molecular sieve was changed to the X-type zeolite molecular sieve, the reaction step conditions were the same as those in Example 1, and a series of white or light gray powder solid X-type silicate-based 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

[0097] Example 3, except that the A-type zeolite molecular sieve was changed to a Y-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 Y-type silicate-based silver ion nanoporous composite materials were obtained. 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 invention belongs to a new application of a silicate-based silver ion nanoporous composite material, and particularly relates to a silicate-based silver ion nanometer prepared from a silicate-based nanoporous material and silver ions or nano-silver ions Application of porous composite materials in antibacterial and sterilization. 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 human beings, such as: Neisseria gonorrhoeae (Neisseriagonorrhoeae), 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 Immune Deficiency Syndrome (AIDSS), which leads to the c...
