Embodiment 1

[0048] A preparation method of an antibacterial activated carbon mask, the steps are as follows: according to the preparation method of an ordinary mask, the outer layer of the photocatalyst melt-blown non-woven fabric, the inner layer of the activated carbon melt-blown non-woven fabric, and the surface layer of the pure cotton spunlace non-woven fabric are cut into The upper and lower heights are 95mm, and the left and right widths are 175mm. The outer layer of photocatalyst melt-blown non-woven fabric, the inner layer of activated carbon melt-blown non-woven fabric, and the surface layer of pure cotton spunlace non-woven fabric are stacked in order from top to bottom. ;Put the nose bridge strip at a distance of 8mm from the upper edge of the photocatalyst melt-blown non-woven fabric, and cover the nose bridge strip with non-woven fabric; place the two ear straps on the outer layer of the photocatalyst melt-blown non-woven fabric respectively Both ends, 5mm away from the upper...

Embodiment 2

[0058] A kind of preparation method of antibacterial active carbon mouth mask is basically consistent with embodiment 1, and its difference is only in:

[0059] The preparation method of described activated carbon melt-blown nonwoven inner layer is:

[0060] (1) Wash the discarded bamboo stalks and dry them at 90°C for 6 hours; then crush them and sieve them to obtain 325-mesh bamboo powder;

[0061] (2) Add 2g of copper nitrate trihydrate and 0.02g of hexamethylenetetramine to 150g of water and stir at a speed of 300r / min for 5min to form solution A; add 5g of bamboo powder in step (1) to solution A and soak for 12h ; After filtering, dry the insoluble matter at 80°C for 6h; then raise the temperature to 700°C in a nitrogen atmosphere at a heating rate of 5°C / min, keep it warm for 2h, and naturally cool to 25°C, wash the powder three times with water and acetone, Dry at ℃ for 6 hours, crush and sieve to obtain 325 mesh copper-doped activated carbon;

[0062] (3) 5g step (2)...

Embodiment 3

[0064] A kind of preparation method of antibacterial active carbon mouth mask is basically consistent with embodiment 1, and its difference is only in:

[0065] The preparation method of described activated carbon melt-blown nonwoven inner layer is:

[0066] (1) Wash the discarded bamboo stalks and dry them at 90°C for 6 hours; then crush them and sieve them to obtain 325-mesh bamboo powder;

[0067] (2) Add 2g of copper nitrate trihydrate and 0.02g of 1-butyl-3-methylimidazole bistrifluoromethanesulfonimide salt into 150g of water and stir for 5min at a speed of 300r / min to form solution A; 5g of step ( 1) Bamboo powder was added to solution A and immersed for 12 hours; after filtration, the insoluble matter was dried at 80°C for 6 hours; then the temperature was raised to 700°C at a heating rate of 5°C / min in a nitrogen atmosphere, kept for 2 hours, and naturally cooled to 25°C. ℃, the powder was washed three times with water and acetone, dried at 60 ℃ for 6 hours, crushed ...

Abstract

The invention discloses an antibacterial activated carbon mask and a preparation method thereof. The antibacterial activated carbon mask comprises a photocatalyst melt-blown non-woven fabric outer layer, an activated carbon melt-blown non-woven fabric inner layer and a pure cotton spunlace non-woven fabric surface layer from outside to inside. The outer layer of the photocatalyst melt-blown non-woven fabric is also provided with ear bands and nose bridge strips, and titanium dioxide doped with metallic nickel and an antibacterial agent prepared from graphene oxide, ferric chloride and bacterial cellulose are added into the photocatalyst melt-blown non-woven fabric layer. According to the antibacterial activated carbon mask, the outer layer with the photocatalytic degradation effect, the copper-doped activated carbon filtering inner layer and the skin-friendly spunlace non-woven fabric surface layer are combined to prepare the antibacterial activated carbon mask, the preparation process is simple, all functional layers are good in cooperation, the antibacterial performance is good, the filtering efficiency on particulate matter is high, and the stable long-term use performance is achieved.

Description

technical field [0001] The invention belongs to the technical field of masks, in particular to an antibacterial activated carbon mask and a preparation method thereof. Background technique [0002] With the continuous development of science and technology, the continuous improvement of people's living standards and the increasingly severe environmental pollution, people's awareness of self-protection has increased, and masks have become a necessity for life. A mask generally refers to a device worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, and droplets from leaching out of the wearer's mouth and nose. Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, when working in dusty and other polluted environments, wearing a mask has a very good effect, especially in cities with severe smog. Items that people must wear when traveling. [0003] Masks o...
