Problems solved by technology

The current 84 disinfectant product is in liquid form, which is inconvenient and unstable during storage and transportation. The release rate of available chlorine is uncontrollable when used. More importantly, 84 disinfectant can only disinfect bacteria and / or viruses that settle on the surface of objects. , and less effective against suspended bacteria and / or viruses suspended in the air for long periods of time
[0005] After polyvinyl alcohol (PVA) forms a gel, microorganisms can be trapped on the surface of the gel, so as to achieve the purpose of retaining microorganisms or immobilizing microorganisms. Therefore, it has received extensive attention in recent years, but the capacity of retaining microorganisms using this method is limited because it is difficult for microorganisms to enter to the inside of the gel and can only be trapped on the surface of the gel, and the ability to fix microorganisms in the air is relatively weak
[0006] Common air disinfection methods include spraying disinfectants such as peracetic acid disinfectant, chlorine dioxide solution, sodium hypochlorite solution, etc., but the disinfection time of this method is too short and the disinfection quality is not high; it also includes fumigated vinegar, ultraviolet lamps, and ozone disinfection machines and other methods, but these methods are inconvenient to use, and often only have a short-term disinfection effect, and have limited effect on suspended bacteria and / or viruses that remain in the air for a long time

Embodiment 1

[0041] Prepare polyvinyl alcohol and sodium hypochlorite mixed solution, wherein polyvinyl alcohol is 5wt%, sodium hypochlorite 15wt%, ethylene glycol 30wt%.

[0042] The specific configuration method is as follows: weigh 5g polyvinyl alcohol (alcoholysis degree 98%, molecular weight 70,000), 15g sodium hypochlorite, 30g ethylene glycol, 50g deionized water. Add polyvinyl alcohol into 30 g of deionized water, stir at room temperature for 12 h, then stir at 95° C. for 10 h until completely dissolved, and cool to room temperature for later use. Add sodium hypochlorite and ethylene glycol to the remaining 20 g of deionized water and stir until completely dissolved. Mix the polyvinyl alcohol solution and the sodium hypochlorite solution evenly, fill it into a plastic box, put it in a freezer at minus 20°C for 20 hours after packaging, take it out to relax at room temperature for 10 hours, and repeat this process 3 times to obtain the sodium hypochlorite hydrogel. Put the plastic ...

Embodiment 2

[0048] A mixed solution of polyvinyl alcohol and sodium hypochlorite is prepared, wherein the mass percentage of polyvinyl alcohol is 7%, sodium hypochlorite is 25%, and ethylene glycol is 27%.

[0049] The specific configuration method is as follows: weigh 7g polyvinyl alcohol (alcoholysis degree 98%, molecular weight 70,000), 25g sodium hypochlorite, 27g ethylene glycol, 41g deionized water. Add polyvinyl alcohol into 30 g of deionized water, stir at room temperature for 12 h, then stir at 95° C. for 10 h until completely dissolved, and cool to room temperature for later use. Sodium hypochlorite and ethylene glycol were added to the remaining 11 g of deionized water and stirred until completely dissolved. Mix the polyvinyl alcohol solution and the sodium hypochlorite solution evenly, fill it into a plastic box, put it in a freezer at minus 20°C for 20 hours after packaging, take it out to relax at room temperature for 10 hours, and repeat this process 3 times to obtain the s...

Embodiment 3

[0055] A mixed solution of polyvinyl alcohol and sodium hypochlorite is prepared, wherein the mass percentage of polyvinyl alcohol is 5%, and sodium hypochlorite is 15%.

[0056] The specific configuration method is as follows: weigh 5g polyvinyl alcohol (alcoholysis degree 98%, molecular weight 70,000), 15g sodium hypochlorite, 80g deionized water. Add polyvinyl alcohol into 50g of deionized water, stir at room temperature for 12h, then stir at 95°C for 10h until completely dissolved, and cool to room temperature for later use. Sodium hypochlorite was added to the remaining 30 g of deionized water and stirred until completely dissolved. Mix the polyvinyl alcohol solution and the sodium hypochlorite solution evenly, fill it into a plastic box, put it in a freezer at minus 20°C for 20 hours after packaging, take it out to relax at room temperature for 10 hours, and repeat this process 3 times to obtain the sodium hypochlorite hydrogel. Put the plastic box in the outer box pack...

Description

technical field [0001] The invention relates to the technical field of disinfectants, in particular to a disinfectant and its preparation method and application. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Chlorine-containing disinfectants are recognized as the most widely used class of chemical disinfectants. It has the advantages of wide bactericidal spectrum, high efficiency, quick effect, low toxicity, low price and convenient use. At present, sodium hypochlorite is the most commonly used chlorine-containing disinfectant. The domestic 84 disinfectant uses sodium hypochlorite as the main active ingredient, which has played a great role in daily life and major epid...
