Mask and preparation method thereof

Abstract

The invention provides a mask and a preparation method thereof. The structure of a main body part of the mask is sequentially divided into a hydrophobic surface layer, a middle layer and an antibacterial skin-care nanofiber layer from outside to inside, wherein the middle layer is composed of the antibacterial nanofiber layer, a supporting fiber layer and a temperature adjusting nanofiber layer. The nanofiber layer is prepared and formed by adopting an electrostatic spinning technology, and the nanofiber layer, the hydrophobic surface layer and a supporting layer are bonded into a whole through ultrasonic welding, hot-pressing compounding or gluing. According to the preparation method, an electrostatic spinning technology and a microcapsule technology are organically combined, and the prepared product is light, thin, soft, excellent in antibacterial performance, stable in temperature regulation performance and remarkable in skin care function while having certain mechanical properties.The mask prepared by the preparation method has good antibacterial ability, good heat storage and temperature adjustment functions and skin care ability, is light and comfortable to wear, greatly reduces respiratory resistance, has excellent filtering performance, and has relatively high application value and wide market prospect.

Description

technical field [0001] The invention relates to the field of sanitary protective products, in particular to a mask with the functions of temperature regulation, antibacterial and skin care and a preparation method thereof. Background technique [0002] The rapid development of industrial civilization has caused more and more environmental problems, such as global warming and poor air quality. Due to the warming of the global climate, plateau glaciers and polar glaciers are thawing, and many frozen ancient viruses and microorganisms are gradually released. At the same time, with the decreasing air quality, these viruses and microorganisms may cause many epidemic diseases. It is a huge threat to human beings on earth. [0003] With the improvement of human safety awareness, in order to cope with the deteriorating air quality and epidemic diseases, people usually use masks for self-protection. At present, there are a variety of masks on the market. According to the definition...

Problems solved by technology

Chinese patent CN201610012431.9 uses nano-silver particles as the antibacterial layer, and adopts electrospray method to spray nano-silver ions onto the spunbonded fabric of the non-woven fabric layer, so that the mask has a certain antibacterial ability, but the nano-silver ion antibacterial agent is only It is attached to the surface of the mask without forming a chemical bond, and the combination is relatively unstable. On the other hand, nano-silver ions have certain migration toxicity, which is not conducive to human health during use.

The above patented methods are only used to prepare masks with a single antibacterial function, and masks with antibacterial functions, temperature regulation functions and skin care functions and their preparation methods are rarely reported
