Problems solved by technology

However, the defect of this patented technology is that the structure is complex and the production cost is high. Only the step of crosslinking or grafting the photocatalyst and the surface of the gauze needs to be equipped with a composite photocatalyst finishing solution. , washing, drying, finishing process, the operation is too complicated, not suitable for large-scale application

Abstract

The invention relates to the technical field of sanitary protective equipment, in particular to a photocatalyst disinfection mask and a preparation method thereof. The photocatalyst disinfection maskincludes a functional layer which includes base materials, function materials are sprayed on the base materials, and the function materials include modified photocatalyst materials and an emulsifyingagent; the preparation method includes the steps that the function materials are mixed to produce suspending liquid and colloidal liquid in sequence; the colloidal liquid is sprayed on the base materials to produce the function materials; and the photocatalyst disinfection mask can be effectively sterilized during insufficient light, and has the characteristics of simple structure, lightness, portability, low production cost and suitable promotion.

Description

technical field [0001] The invention relates to the technical field of sanitary protection articles, in particular to a photocatalyst disinfection mask and a preparation method thereof. Background technique [0002] Mask is a kind of commonly used sanitary protective equipment, which can keep warm, prevent dust, prevent bacteria, deodorize and so on. During the outbreak of airborne diseases such as influenza and SARS, masks can play a certain role in isolating germs. Masks in hospitals can also play a certain role in isolating germs. [0003] Photocatalyst is a general term for a photo-semiconductor material with photocatalytic function represented by nano-scale titanium dioxide. It is coated on the surface of the substrate, and under the action of ultraviolet light, it produces a strong catalytic degradation function: it can effectively degrade toxic substances in the air. Harmful gas; can effectively kill a variety of bacteria, and can decompose and harmlessly treat the ...
