Antibacterial and environment-friendly mask containing zedoary oil nano-particle coating and preparation method thereof

Abstract

The invention discloses an antibacterial and environment-friendly mask containing a zedoary oil nano-particle coating and a preparation method thereof. The antibacterial and environment-friendly maskcomprises a mask body and lacing belts arranged on the two sides of the mask body. The mask body comprises an inner layer cloth, an antibacterial filtering layer and an outer layer cloth which are sequentially arranged from inside to outside. The antibacterial filtering layer comprises a spunlace non-woven fabric layer serving as a first layer and the zedoary oil nano-particle coating serving as asecond layer. The zedoary oil nano-particle coating is composed of zedoary oil nano-particles, and the diameter of air-permeable pores of the nano coating is less than 2.5 nm. On the one hand, the antibacterial and environment-friendly mask is fresh and pleasant and has the good effect of preventing and killing bacteria and microorganisms; and on the other hand, the adopted spunlace non-woven fabric material is safe, environmentally friendly, low in cost, simple in production and suitable for industrial production, adopted production materials are free of pollution, disposable materials can be naturally degraded harmlessly, and thus the more environment-friendly effect is achieved.

Description

Technical field: [0001] The invention relates to the technical field of health protection products, in particular to an antibacterial and environmentally friendly mask containing zedoary oil nanoparticle coating and a preparation method thereof. Background technique: [0002] At present, the mask cover widely used in the market is composed of fabrics and multi-layer filters. The fabrics can be ordinary fabrics or antibacterial fabrics such as nano-silver. The filter is made of meltblown cloth, or filled with activated carbon and traditional Chinese medicine particles. The mask made by this technology can only filter and block non-oily particles such as dust (particle size greater than 2.5nm). If you want to filter smog particles (PM2.5) or fine bacteria with a particle size of less than 2.5nm, you need to use a meltblown cloth filter with a smaller pore size, and use a meltblown cloth filter with a pore size smaller than 2.5nm to make a mask. There are three disadvantages. ...

AI Technical Summary

Problems solved by technology

If you want to filter smog particles (PM2.5) or fine bacteria with a particle size of less than 2.5nm, you need to use a meltblown cloth filter with a smaller pore size, and use a meltblown cloth filter with a pore size smaller than 2.5nm to make a mask. There are three disadvantages. The first point is that the air permeability is poor, the breathing resistance is large, and it cannot meet the standard requirements.

The third point is that there is no antibacterial and sterilizing function, and the active protection function
