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

Abstract

The invention provides a multifunctional mask and a preparation method thereof. A main body part of the multifunctional mask is formed by overlapping an antimicrobial nanofiber layer prepared by electrostatic spinning and provided with antimicrobial microcapsules, a temperature adjusting nanofiber layer containing temperature adjusting microcapsules and a skin protection antibacterial nanofiber layer containing antimicrobial microcapsules and skin protection microcapsules, wherein the skin protection antibacterial nanofiber layer is located in an innermost layer close to the face. According tothe preparation method, a microcapsule technology and an electrostatic spinning technology are organically combined; the advantages of two technologies are fully coordinated; and the mask prepared bythe preparation method maintains a good protection function, also has a good antimicrobial capability, a temperature adjusting capability and a skin protection capability, and is safe to use and widein application.

Description

technical field [0001] The invention relates to the field of sanitary protective products, in particular to a multifunctional mask with 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 th...
