Embodiment 1

[0031] A preparation method of a novel dustproof, antibacterial and antiviral nanofiber mask, comprising the following steps:

[0032] (1) The preparation method of ordinary non-woven fabric layer: in the form of melt blowing, the high-speed hot air flow drafts the thin stream of polyethylene melt extruded from the spinneret hole of the die head, and the formed fibers are collected on the drum, and at the same time Self-bonding to prepare melt-blown non-woven fabrics.

[0033] (2) The preparation method of drug-loaded nano-microspheres is as follows:

[0034] Dissolve cetyltrimethylammonium bromide surfactant in water, keep stirring at 60°C for 1 hour, add triethanolamine and ethyl orthosilicate in sequence, cetyltrimethylammonium bromide: triethanolamine: Ethyl orthosilicate: water = 0.4g: 0.3g: 6mL: 80mL, stirred and reacted and then centrifugally filtered, the obtained filter residue was dried at 80°C for 6h, and calcined in a muffle furnace at 300°C for 3h to obtain powde...

Embodiment 2

[0039] A preparation method of a novel dustproof, antibacterial and antiviral nanofiber mask, comprising the following steps:

[0040] (1) The preparation method of ordinary non-woven fabric layer: in the form of melt blowing, the high-speed hot air flow drafts the thin stream of polyacrylonitrile melt extruded from the spinneret hole of the die head, and the formed fibers are collected on the condensed net curtain , At the same time, it is self-adhesive to prepare a melt-blown non-woven fabric.

[0041] (2) The preparation method of drug-loaded nano-microspheres is as follows:

[0042] Dissolve sodium dodecylbenzenesulfonate surfactant in water, keep stirring at 80°C for 0.5h, add triethanolamine and ethyl orthosilicate in sequence, sodium dodecylbenzenesulfonate: triethanolamine: orthosilicate Ethyl ester: water = 1g: 0.8g: 10mL: 100mL, after stirring and reacting, centrifugal suction filtration, the resulting filter residue was dried at 80°C for 4h, and calcined at 400°C f...

Embodiment 3

[0048] A preparation method of a novel dustproof, antibacterial and antiviral nanofiber mask, comprising the following steps:

[0049] (1) The preparation method of ordinary non-woven fabric layer: in the form of melt blowing, the high-speed hot air flow drafts the thin stream of PVC melt extruded from the spinneret hole of the die head, and collects the formed polyvinyl chloride on the condensate screen fibers, and at the same time bond themselves to prepare melt-blown non-woven fabrics.

[0050] (2) The preparation method of drug-loaded nano-microspheres is as follows:

[0051] Dissolve sodium dodecylbenzenesulfonate surfactant in water, keep stirring at 80°C for 2 hours, add triethanolamine and ethyl orthosilicate in sequence, sodium dodecylbenzenesulfonate: triethanolamine: ethyl orthosilicate Ester: water = 1g: 0.8g: 10mL: 100mL, after stirring and reacting, centrifugal suction filtration, the resulting filter residue was dried at 80°C for 5h, and calcined at 450°C for 2...

Abstract

The invention belongs to the field of ultrafiltration materials and the field of health protection technology, and specifically relates to a novel dustproof, antibacterial and antiviral nanofiber mask, which includes a mask main body, and is characterized in that: the mask main body sequentially includes non-woven fabrics from inside to outside Layer, multi-layer drug-loaded composite fiber film layer and non-woven fabric layer, the multi-layer drug-loaded composite fiber film layer includes at least three layers, the inner and outer layers are meltblown layers or electrospun fiber film layers, and the middle layer It is a fiber membrane layer loaded with drug-loaded nano microspheres. The multi-layer drug-loaded composite fiber membrane layer used in the present invention can enhance the slow-release performance, anti-virus and anti-bacterial properties of drugs through drug-loaded nano-microspheres and various mesoporous structures formed by different materials, and enhance the filtration of particulate matter and odor in the air It has a strong killing and inhibiting effect on public health safety, respiratory system, and infectious viruses.

Description

technical field [0001] The invention belongs to the field of ultrafiltration materials and the technical field of health protection, and in particular relates to a novel dustproof, antibacterial and antiviral nanofiber mask. Background technique [0002] A mask is a kind of sanitary protection product, which is generally worn on the mouth and nose. It can be used to filter the air entering the mouth and nose, and has the function of blocking harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose. The mask has a certain filtering effect on the air entering the lungs. When working in an environment polluted by respiratory infectious diseases or dust, the mask is a very necessary protective tool. From the outbreak of SARS virus to the new coronavirus, as well as the occasional bird flu virus and H1N1 virus that occur all over the world, it also seriously threatens the life and health of human beings. The size of these germs is generally about ...
