Embodiment 1

[0018] A nano-silver antibacterial and anti-viral combination solution in this embodiment is prepared from nano-silver colloid and polyvinylpyrrolidone, and its main components are complexes of polyvinylpyrrolidone and silver, silver nanoparticles, polyvinylpyrrolidone and water. . The elemental silver nanoparticles contained in the nano-silver colloid used as raw materials, 90% of the particle diameters are distributed between 1 nanometer and 20 nanometers, and the silver content is 234mg / L, which is weakly alkaline; the amount of polyvinylpyrrolidone used as raw materials is 3% of the weight of nano silver colloid.

[0019] Its preparation method is as follows: under normal temperature and pressure, adopt the nano-silver colloid (formed by "A production equipment and method for nano-silver colloid" [200810086707.3] patented technology production), adding 3% polyvinylpyrrolidone "PVP-K90" (purchased from American Special Products Co., Ltd.) Dissolved, then sealed and protec...

Embodiment 2

[0022] A nano-silver antibacterial and anti-viral combination solution of the present embodiment is prepared from nano-silver colloid and polyvinylpyrrolidone, wherein 90% of the particle diameters of the elemental silver nanoparticles contained in the nano-silver colloid are distributed between 1 nanometer and 20 nanometers. Between, the silver content is 3mg / L, it is weakly alkaline; and the amount of polyvinylpyrrolidone used is 0.01% of the weight of nano-silver colloid.

[0023] Its preparation method is as follows: under normal temperature and pressure, adopt the nano-silver colloid (formed by "A production equipment and method for nano-silver colloid" [200810086707.3] patented technology production), adding polyvinylpyrrolidone "PVP-K90" (purchased from American Special Products Co., Ltd.) with 0.01% of the weight of the nano-silver colloid used and stirring until fully Dissolved, then sealed and protected from light for thirty days, so that the silver ions and polyviny...

Embodiment 3

[0026]A nano-silver antibacterial and anti-viral combination solution of the present embodiment is prepared from nano-silver colloid and polyvinylpyrrolidone, wherein 90% of the particle diameters of the elemental silver nanoparticles contained in the nano-silver colloid are distributed between 1 nanometer and 20 nanometers. Between, the silver content is 1000mg / L, it is weakly alkaline; and the amount of polyvinylpyrrolidone used is 10% of the weight of the nano-silver colloid.

[0027] Its preparation method is as follows: under normal temperature and pressure, adopt the nano-silver colloid (formed by "A production equipment and method for nano-silver colloid" [200810086707.3] patented technology production), add polyvinylpyrrolidone "PVP-K90" (purchased from American Special Products Co., Ltd.) with 10% of the weight of the nano-silver colloid used, and stir until fully Dissolved, then sealed and protected from light for thirty days, so that the silver ions and polyvinylpyr...

Abstract

The invention discloses a nanometer silver antibiotic and antiviral compound liquid and its preparation method and products. The compound liquid is prepared by using materials of nanometer silver colloid and polyvinylpyrrolidone, wherein the weight of polyvinylpyrrolidone is 0.01-40% of the weight of the nanometer silver colloid. The invention solves problem that the silver nanometer particles have poor affinity with cells and partially coagulate in long-term preservation when the nanometer silver colloid is in antibiotic and antiviral practical application; the nanometer silver antibiotic and antiviral compound liquid has characteristics of practicability, economy, intoxicity and high efficiency.

Description

technical field [0001] The invention relates to a nano-silver antibacterial and antiviral combination liquid, a preparation method and a product thereof. Background technique [0002] Over the years, the destruction of the environment by humans and the abuse of antibiotics have resulted in the emergence of drug-resistant bacteria and mutated viruses, which have seriously threatened people's health. While the country is strengthening environmental governance and restricting the casual use of antibiotics, scientists have begun to pay attention to the antibacterial Nano-silver, which is not easy to drug resistance and anti-virus, can be applied to actual disease prevention and treatment for research. With the in-depth research on nano-silver, its antibacterial and broad-spectrum advantages are beyond doubt, and its anti-viral effect has been continuously confirmed and announced. In Vitro Anti-HIV Activity Research", the content of "Experimental Research on Inhibition of Season...
