Embodiment 1
[0036] A bactericidal film with bactericidal function, calculated by weight, select the following components for preparation: Bordeaux mixture 15.3, antifungal agent 0.3; spray film-forming agent, water-based polyurethane dispersion 45.5, water 12.7, dimethyl silicone oil 4.6, isopropanol 11.2; in the adjustment auxiliary materials, defoamer 0.17, wetting agent 0.2, leveling agent 0.5, thickener 0.31.
[0037] The preparation steps are:
[0038] S1. Put 127g of water in the reaction kettle, add 112g of isopropanol to the water to ensure the diffusivity of the liquid, then add 153g of Bordeaux mixture, and stir evenly;
[0040] S21, the first choice is to carry out conditioning treatment on the liquid, add 1.7g defoamer, 2g wetting agent, 5g leveling agent and 3g antifungal agent, and stir for 10 minutes;
[0041] S22, then add the main film-forming material in step S21, that is, first add 455g of water-based poly...
Embodiment 2
[0046] A kind of antibacterial film with bactericidal function, calculated by weight, select: Bordeaux mixture 19.5, antifungal agent 0.12; in spray film forming agent, water-based polyurethane dispersion 53, water 18, dimethyl silicone oil 7.8, isopropanol 13.4; Adjusting auxiliary materials, defoamer 0.24, wetting agent 0.24, leveling agent 0.4, thickener 0.37.
[0047] The preparation steps are:
[0048] S1. Put 180g of water in the reaction kettle, add 134g of isopropanol to the water to ensure the diffusibility of the liquid, then add 195g of Bordeaux mixture, and stir evenly;
[0050] S21, the first choice is to carry out conditioning treatment on the liquid, add 2.4g defoamer, 2.4g wetting agent, 4g leveling agent and 1.2g antifungal agent, and stir for 10 minutes;
[0051]S22, then add the main film-forming material to step S21, that is, first add 530g of water-based polyurethane dispersion, slowly add 78...

Abstract
The invention relates to a degerming film with a sterilization function, which is used for protecting the surface of an article and removing or preventing bacteria. The degerming film is sprayed on the surface of an article to form a film during degerming, so that the surface of the article is protected from being scratched, and meanwhile, a special sterilization function is also realized. Bacteria cannot survive on the surface of the protective film within a certain period of time. The degerming protective film comprises a bactericide, a mildew preventive and a spraying film-forming agent, and the spraying film-forming agent comprises waterborne polyurethane dispersoid, water, dimethyl silicone oil and isopropanol. The invention further discloses a preparation process and application of the degerming film with a sterilization function. The degerming film has the advantages of being rapid and convenient in sterilization, good in sterilization effect, long in sterilization time, capableof achieving rapid drying, free of object moisture and wide in application range.
Description
technical field [0001] The invention relates to the technical field of sterilization, in particular to a sterilization film with a sterilization function and its preparation process and application. Background technique [0002] Ordinary sterilizing liquid usually exists in the form of liquid. When it is used to sterilize items, it is easy to make the items wet and corrosive. Therefore, the scope of application is not particularly wide, and it can only be used for simple disinfection and sterilization. [0003] Now a kind of adhesive film gradually appeared on the market, which is covered on the article, and the bacteria can be removed by tearing it off. However, its degree of adhesion to objects is not particularly high, and it simply depends on its stickiness. [0004] For this reason, the applicant has designed a kind of antibacterial film with bactericidal function, it is used for sterilizing, is contained in the bottle with the form of liquid, forms film after spraying...
