Problems solved by technology

[0006] The technical problem to be solved by the present invention is that the cost of the existing masks is high, the preparation process is complicated, and the antibacterial agent is easy to fall off due to the insufficient composite property with the base, and cannot play the role of dust absorption, antibacterial, and deodorization. The function is to provide a new type of mask with simple preparation method, good dust adsorption performance, excellent antibacterial and deodorizing properties, and good isolation effect on infectious bacteria and viruses that are easy to spread through air and other media.

Embodiment 1

[0037] Mix graphene oxide, tannic acid, and silver nitrate in a 0.2M sodium hydroxide solution at a mass ratio of 1:10:0.2, and then react at 80°C for 1 hour in the dark to prepare the green antibacterial material graphene oxide-tannic acid - Nanosilver.

[0038]A water mixture of green antibacterial material graphene oxide-tannic acid-nanosilver was prepared with a concentration of 50 μg / mL. Then use compressed air to spray the antibacterial mixed solution on the non-woven fabric, the average spraying amount is 0.03mL / cm 2 .

[0039] Arrange the sprayed non-woven fabric inside the mask, and place it on the second layer from the layer close to the mouth, where the sol non-woven fabric layer is the third layer from the layer close to the mouth, close to the mouth and the outermost The layers are high-quality protective non-woven fabrics.

Embodiment 2

[0041] Mix graphene oxide, tannic acid, and silver nitrate in a 0.5M sodium hydroxide solution at a mass ratio of 1:30:0.2, and then react at 100°C in the dark for 5 hours to prepare the green antibacterial material graphene oxide-tannic acid - Nanosilver.

[0042] A water mixture of green antibacterial material graphene oxide-tannic acid-nanosilver with a concentration of 500 μg / mL was prepared. Then use compressed air to spray the antibacterial mixed solution on the non-woven fabric, the average spraying amount is 1mL / cm 2 .

[0043] Arrange the sprayed non-woven fabric inside the mask, and place it on the third layer from the layer close to the mouth, where the sol non-woven layer is the second layer from the layer close to the mouth, close to the mouth and the outermost The layers are high-quality protective non-woven fabrics.

Embodiment 3

[0045] Mix graphene oxide, tannic acid, and silver nitrate in 0.3M sodium hydroxide solution at a mass ratio of 1:20:0.2, and then react at 90°C for 2 hours in the dark to prepare the green antibacterial material graphene oxide-tannic acid - Nanosilver.

[0046] A water mixture of green antibacterial material graphene oxide-tannic acid-nanosilver was prepared with a concentration of 150 μg / mL. Then use compressed air to spray the antibacterial mixed solution on the non-woven fabric, the average spraying amount is 0.5mL / cm 2 .

[0047] Arrange the sprayed non-woven fabric inside the mask, and place it on the second layer from the layer close to the mouth, where the sol non-woven fabric layer is the third layer from the layer close to the mouth, close to the mouth and the outermost The layers are high-quality protective non-woven fabrics.

Abstract

The invention discloses an antibiotic anti-haze green mouth mask based on oxidized graphene and a manufacturing method and belongs to the medical health and medical protection field. The antibiotic anti-haze green mouth mask comprises multiple layers of non-woven fabrics, one layer of the non-woven fabrics contains a compound antibiotic green material of oxidized graphene-tannic acid-nanometer silver, and the antibiotic green compound material has filtering and anti-microbic effects and has great inhibition and killing effects on bacteria and fungi microbes. The mouth mask has antibiotic and peculiar smell removing functions, the compound antibiotic material layer is nontoxic and has no pollution, the manufacturing technology is simple, and excellent ventilation performance is further realized. The manufacturing method is simple, breathing resistance of a high-efficiency anti-influenza face mask is not only reduced, but also cross infection caused the mouth mask itself can be avoided, relatively good market potential is realized.

Description

technical field [0001] The invention relates to the technical field of antibacterial masks, in particular to a green antibacterial anti-haze mask based on graphene oxide and a preparation method thereof. Background technique [0002] In recent years, due to the acceleration of industrialization and the intensification of various pollutions, the living environment of human beings has continued to deteriorate, and the potential invasion opportunities of infectious viruses and germs have increased. Respiratory tract infectious diseases spread quickly through droplets and air. The high rate poses a great threat to public health and social stability; at the same time, many cities in my country have experienced a certain degree of smog weather. PM2.5 is medically called inhalable particulate matter, which is the diameter of particulate matter in the atmosphere less than or equal to For pollutants of 2.5 microns, the general masks on the market currently have poor filtering effect on...
