Abstract

The invention belongs to the technical field of masks, and relates to a sterilization and disinfection mask adopting a photocatalysis apatite wrapping technology. The sterilization and disinfection mask comprises a sterilization and disinfection outer layer and a textile fabric inner layer contacting with a human face; the sterilization and disinfection outer layer comprises base layer cloth; the surface of the base layer cloth is coated with an apatite-nanometer titanium dioxide composite photocatalyst; and the base cloth is composed of nano-silver fibers, bamboo charcoal fibers and photocatalytic fibers. According to the mask, the outer layer of the mask is coated with the composite photocatalyst which is made of titanium dioxide and apatite and serves as a main sterilization and disinfection action object, the photocatalysis, sterilization and disinfection efficiency of titanium dioxide is integrally improved, and the mask has a long-acting use effect.

Description

technical field [0001] The invention belongs to the technical field of masks, in particular to a photocatalytic apatite wrapping technology for sterilization and disinfection masks. Background technique [0002] Mask is a kind of sanitary product, which is generally worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, droplets, viruses and other substances, and is made of gauze or paper. Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, wearing a mask has a very good effect when working in a polluted environment such as dust. Yet its sterilizing effect of mouth mask in the prior art is unsatisfactory, can not satisfy the use requirement under the special environment. [0003] PCM is the abbreviation of photocatalysis, known internationally as photocatalyst, which is a catalyst that converts light energy into chemical energy. The principle of PCM ...
