preparation example Construction

[0048] In one embodiment, the preparation method of the bactericidal layer comprises the steps of:

[0049] Dissolving the bactericidal material in a solvent to obtain a bactericidal solution;

[0050] The non-woven fabric, woven fabric or polymer film is coated (such as spin-coated), sprayed or soaked with the bactericidal solution, and then dried.

[0051] Further in one embodiment, the solvent may be selected from but limited to at least one of methanol, ethanol, isopropanol and water.

[0052] Further in one embodiment, in the bactericidal solution, the mass concentration of the bactericidal material is 0.01-5 wt%, for example, 1 wt%.

[0053] In one embodiment, both the inner non-woven fabric layer and the outer non-woven fabric layer are made of at least one of polypropylene, polyester fiber, polyamide, polyacrylonitrile and polyvinyl chloride fiber Non-woven layer.

[0054] In one embodiment, the polyvinyl fluoride film can be made of polytetrafluoroethylene, a copol...

Embodiment 1

[0056] Embodiment 1 copolymer P1-1 (R 3 =H,X 2 - = Cl - ) preparation

[0057] According to reaction formula (1-1), Specifically include steps: 116g (1mol) N 1 ,N 1 ,N 2 ,N 2 -Tetramethyl-1,2-ethylenediamine (A-1), 112g (1mol) 1,4-vinylpiperazine (A-2), 66g (0.5mol) 1,2-bis(dimethylamino ) ethanol (A-3), 146g (0.5mol) ethylenediaminetetraacetic acid (A-4-1) and 1L dichloroethyl ether (A-5-1) mixed with 500mL water, stirred at 30°C for 30 minutes , refluxed for 8 hours, cooled, concentrated to remove the solvent, precipitated a solid with acetone, and dried under vacuum to obtain 328 g of copolymer P1-1.

Embodiment 2

[0058] Embodiment 2 copolymer P1-2 (R 3 =H,X 2 - =ClO 4 - ) preparation

[0059] According to reaction formula (1-2), The specific steps include: heating 100g of copolymer P1-1 and 200mL of perchloric acid aqueous solution to reflux, cooling and crystallizing after the reaction, washing with acetone, draining, and vacuum drying to obtain 109g of copolymer P1-2.

Abstract

The invention discloses an efficient antibacterial mask. Specifically, one or more layers of all layers of a mask body of an existing mask are loaded with the sterilization material with the specificstructure; or the efficient antibacterial mask containing the sterilizing layer is formed by additionally arranging the functional layer loaded with the sterilizing material with the specific structure in the mask body of the existing mask; according to the mask with the sterilization function, an existing mask has the sterilization function, microorganisms, bacteria and viruses adsorbed on the mask can be killed in time, and therefore the mask and the blocking layer with the physical protection function can play a better protection role, the service life of the mask can be prolonged, resourcewaste is reduced, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of respiratory protection products, in particular to a high-efficiency antibacterial mask. Background technique [0002] For diseases transmitted through the respiratory tract or droplets, masks have become a must-have, especially since the outbreak of the new coronavirus around the world, wearing masks has become a necessity for people to travel. At present, most of the masks on the market are disposable physical protective masks, which absorb droplets, microorganisms and dust through static electricity. However, the microorganisms adsorbed on the masks cannot be killed, and the used masks are also very troublesome to dispose of, causing environmental pollution and may also lead to secondary transmission of the virus. Therefore, it is imminent to develop a kind of mouth mask with bactericidal function. The mask with bactericidal function can kill the virus / bacteria adsorbed on the mask in time, and can ki...
