[0034] Antibacterial and antiviral tests are carried out on the above-mentioned film with antibacterial and antiviral functions, and the result is that the antibacterial rates of the antibacterial and antiviral coating to Escherichia coli (ATCC 25922) and Staphylococcus aureus (ATCC 6538P) are respectively 90% and 90%. The killing rate of H1N1 virus is more than 90.0%.

Embodiment 3

[0036] An antibacterial and antiviral functional film, comprising the following components by weight: 22 parts by weight of water-soluble polyurethane emulsion, 10 parts by weight of nano silver, organic antibacterial agent (4,5-dichloro-2-n-octyl- 3-isothiazolinone) 5 parts by weight, 15 parts by weight of propylene glycol and 31 parts by weight of water.

[0037] Antibacterial and antiviral tests are carried out on the above-mentioned film with antibacterial and antiviral functions. The result is that the antibacterial rates of the antibacterial and antiviral coating to Escherichia coli (ATCC 25922) and Staphylococcus aureus (ATCC 6538P) are respectively 99.99% and 99.99%. The killing rate of H1N1 virus is more than 90.0%.

[0038] The preparation method of the antibacterial and antiviral functional film described in each of the above-mentioned embodiments is prepared through the following steps:

[0039] Step A: Mix and disperse the organic antibacterial agent, water, and ...

Abstract

The invention discloses a preparation method of an antibacterial and antiviral functional film. The antibacterial and antiviral functional film is prepared from the following raw materials in parts by weight: 22-30 parts of a water-soluble polymer adhesive, 5-10 parts of nano-silver sol, 2-10 parts of an organic antibacterial agent, 5-15 parts of auxiliaries and 31-60 parts of water. The antibacterial and antiviral functional film is high in use safety, the quick-acting antibacterial rate of the treated film surface reaches 99% or above, and the film is very good in quick-acting killing effect on influenza A virus (H1N1), non-toxic, non-irritant to skin and very good in long-acting lasting effect.

Description

technical field [0001] The invention belongs to the field of antibacterial and antiviral technology, and in particular relates to a preparation method of an antibacterial and antiviral functional film. Background technique [0002] At the beginning of 2020, a sudden epidemic affected human health, and a safe and healthy living environment has increasingly become everyone's pursuit goal. With the outbreak of the epidemic, harmful bacteria and viruses in the living environment have also attracted people's attention, and antibacterial and antiviral have become an important task for people to protect their health. In order to inhibit the reproduction and reproduction of bacteria and viruses, two methods are currently used to treat the film: one is to directly add antibacterial and antiviral masterbatches in proportion to the plastic particles, and then go through the corresponding film making process to obtain the final required Functional film. However, this method has high r...
