Problems solved by technology

However, traditional hand sanitizers still have contact during use, and traditional soaps also have defects that are not easy to carry or have no antibacterial and antiviral functions
Although soap paper has appeared at present, most of them are soap paper, which only has decontamination function and no antibacterial function, which does not meet people's requirements for safety and health at the present stage, such as the soap paper invented by the patent No. CN201510413977.0

Embodiment 1

[0035] Disposable nano antibacterial soap paper, the specific steps of preparation are as follows:

[0036] (1) First inject sodium hydroxide solution in the container, vibrate, then heat and boil; after pouring out the sodium hydroxide, wash it with distilled water for later use, add 20mL concentration to the container and be 0.05mmol / mL silver nitrate solution; Under stirring, add ammonia water drop by drop to 20 mL of silver nitrate solution with a concentration of 0.05 mmol / mL until the precipitate just dissolves to obtain a silver ammonia solution;

[0037] (2) adding the silver ammonia solution that step 1 obtains to 20mL concentration is that 0.05mmol / mL sodium carboxymethyl cellulose solution is mixed, then dripped into the 0.5wt% montmorillonite solution that has been swelled by water absorption, Microwave stirring reaction (reaction time 30min, reaction temperature 60°C, power 500W) to obtain silver-loaded sodium carboxymethylcellulose / montmorillonite antibacterial m...

Embodiment 2

[0043] Disposable nano antibacterial soap paper, the specific steps of preparation are as follows:

[0044] (1) First inject sodium hydroxide solution in the container, vibrate, then heat and boil; after pouring out the sodium hydroxide, wash it with distilled water for later use, add 20mL concentration to the container and be 0.05mmol / mL silver nitrate solution; Under stirring, add ammonia water drop by drop to 20 mL of silver nitrate solution with a concentration of 1 mmol / mL until the precipitate just dissolves to obtain a silver ammonia solution;

[0045] (2) adding the silver ammonia solution obtained in step 1 to 200 mL concentration of 1 mg / mL sodium carboxymethyl cellulose solution and mixing, then dripping into 10 mL concentration of 1 wt% montmorillonite solution that has been swollen by water absorption, microwave stirring Reaction (reaction time 70min, reaction temperature 85°C, power 800W) to obtain silver-loaded sodium carboxymethylcellulose / montmorillonite antib...

Embodiment 3

[0051] Disposable nano antibacterial soap paper, the specific steps of preparation are as follows:

[0052] (1) First inject sodium hydroxide solution in the container, vibrate, then heat and boil; after pouring out the sodium hydroxide, wash it with distilled water for later use, add 20mL concentration to the container and be 0.05mmol / mL silver nitrate solution; Under stirring, add ammonia water drop by drop to 20 mL of silver nitrate solution with a concentration of 3 mmol / mL until the precipitate just dissolves to obtain a silver ammonia solution;

[0053] (2) Add the silver ammonia solution that step 1 obtains to 600mL concentration and mix in 3mg / mL sodium carboxymethyl cellulose solution, then drop into 6mL concentration that has been swelled by water absorption and be 3wt% in the montmorillonite solution, microwave stirring Reaction (reaction time 80min, reaction temperature 90°C, power 1000W) to obtain silver-loaded sodium carboxymethylcellulose / montmorillonite antibac...

Abstract

The invention discloses disposable nano-antibacterial soap paper as well as a preparation method and an application thereof. The method comprises the following steps: preparing nano-silver by adopting sodium carboxymethyl cellulose as a reducing agent and a stabilizing agent, and meanwhile, intercalating the nano-silver into montmorillonite (MTT) lamellas to peel off the lamellas, so as to prepare a silver-loaded sodium carboxymethyl cellulose / montmorillonite composite antibacterial agent; and mixing with a nano cellulose (CNF) solution, adding into the soap liquid, and preparing the disposable soap paper by using a suction filtration film forming method. The silver-loaded sodium carboxymethyl cellulose / montmorillonite disposable nano antibacterial soap paper has an inhibition zone diameter of 4.68 mm for staphylococcus aureus and an inhibition zone diameter of 5.70 mm for escherichia coli, and has excellent antibacterial performance; meanwhile, the soap paper also has various properties such as good convenience, foamability, detergency, biodegradability and dissolvability, and meets the requirements of current crowds on healthy, portable and environment-friendly soap paper.

Description

technical field [0001] The invention relates to the field of public health and health, in particular to a disposable nano antibacterial soap paper and its preparation method and application. Background technique [0002] In normalized epidemic prevention, including daily cleaning, timely hand washing is one of the important means to control the spread of germs and prevent the development of infection. However, traditional hand sanitizers still have contact during use, and traditional soaps also have defects that are not easy to carry or have no antibacterial and antiviral functions. Although soap paper has appeared at present, most of them are soap paper, which only has decontamination function and no antibacterial function, and does not meet people's requirements for safety and health at the present stage, such as the soap paper invented by CN201510413977.0. Therefore, it is of great significance to develop portable soap paper with antibacterial and antiviral properties. ...
