Abstract

The invention belongs to the technical field of masks, and in particular relates to a sterilization and disinfection mask with a photocatalytic apatite wrapping technology, comprising a sterilization and disinfection outer layer and a textile inner layer in contact with a human face, wherein the sterilization and disinfection outer layer comprises a base fabric, and the The surface of the base fabric is coated with apatite-nano-titanium dioxide composite photocatalyst, and the base fabric is composed of three kinds of fibers: nano-silver fibers, bamboo charcoal fibers and photocatalytic fibers. The present invention improves the photocatalysis, sterilization and disinfection efficiency of titanium dioxide as a whole by coating the composite photocatalyst with titanium dioxide and apatite as materials on the outer layer of the mask as the main sterilization and disinfection agent, and the mask of the present invention has The effect of long-term use.

Description

technical field [0001] The invention belongs to the technical field of masks, and in particular relates to a sterilization and disinfection mask with photocatalytic apatite wrapping technology. Background technique [0002] A mask is a kind of hygiene product, which is generally worn on the mouth and nose to filter the air entering the mouth and nose to block harmful gases, odors, droplets, viruses and other substances. It is made of gauze or paper. Masks have a certain filtering effect on the air entering the lungs. Wearing masks has a very good effect when working in a polluted environment such as dust when respiratory infectious diseases are prevalent. However, the sterilization and disinfection effect of the masks in the prior art is not ideal, and cannot meet the use requirements in special environments. [0003] PCM is the abbreviation of photocatalysis, which is called photocatalyst in the world. It is a catalyst that converts light energy into chemical energy. The ...
