Problems solved by technology

Among them, the antibacterial effect of inorganic silver-based antibacterial agents is outstanding, but due to the strong sensitivity of silver ions to light, it is easy to oxidize and change color, which has become an important problem that limits its application. In addition, the cost of silver-based antibacterial agents is also very high.

Embodiment 1

[0059] Method 1: Take 1000g of A-type silicate nanoporous material and 1000g of zinc nitrate, put them into a reaction vessel, stir evenly under dark conditions, then transfer to a muffle furnace and heat at 500°C for 5 hours. After cooling, a white or light gray powder solid type A silicate-based zinc oxide ion nanoporous composite material is obtained.

[0060] Method 2: get A-type silicate nanoporous material 1000g, add in the reaction vessel that fills distilled water, add zinc nitrate under stirring, dark condition, reaction mixture mass ratio is nanoporous material: water: zinc nitrate=1: 20:0.8. Then it was stirred at room temperature for 10 hours. After the reaction was completed, the product was filtered, and the final product was dried in the range of 80°C, and then transferred to a muffle furnace for heating and reacting in the range of 500°C for 5 hours. A type A silicate-based zinc oxide ion nanoporous composite material is also obtained.

[0061] In the above ...

Embodiment 2

[0062] 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 zinc oxide ion nanoporous composite materials were obtained. The unit cell is: Zn 43-X / 2 Na X [Al 86 Si 106 o 384 ]0-264ZnO (x=0.1-86).

Embodiment 3

[0063] Example 3. Except changing the A-type zeolite molecular sieve to 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 zinc oxide ion nanoporous composite materials were obtained. The unit cell is: Zn 28-X / 2 Na X [Al 56 Si 136 o 384 ]0-264ZnO (x=0.1-55).

Abstract

The invention relates to a silicate-based zinc oxide ion nano-pore composite material prepared from a nano-pore material and a zinc source and the application of the material in antibacterial and bactericidal aspects. Nanoporous materials include: A-type zeolite molecular sieves, X and Y-type zeolite molecular sieves, mordenite molecular sieves, silica-alumina zeolite molecular sieves and silica-alumina mesoporous molecular sieves. The material can be widely used for anti-dermatophytes and various pathogenic fungi, as well as anti-Candida bacteria, Saccharomyces bacteria, Penicillium bacteria, Aspergillus bacteria, Alternaria bacteria, Fusarium bacteria or Bacteria spp. Especially for 10 common bacteria such as Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Bacillus cereus, it has a certain effect of killing and inhibiting growth. It can be used in food, medicine, health care products, cosmetics and other industries to prepare products with bactericidal, bacteriostatic and antibacterial effects, such as packaging materials, various utensils and various forms of skin care products and pharmaceuticals that are widely used and accepted today products etc.

Description

technical field [0001] The invention belongs to a new application field of silicate-based zinc oxide ion nanoporous composite materials, and specifically relates to a silicate-based zinc oxide prepared from silicate-based nanoporous materials, nano-zinc oxide particles and zinc ions Ionic nanoporous composite material and its application 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 pathogenicity of peptic ulcer and gastric cancer. HIV causes acquired immunodeficiency syndrome (AIDS), wh...
