Mask and a production method therefor

Abstract

A mask and a method of manufacturing the same that intercept a virus are provided. The mask includes: a mask body; an exhalation module that is formed at one surface of the mask body; and an inhalation module that is formed at the one surface of the mask body and that includes an inhalation filter. The inhalation filter includes an anodized aluminum oxide film.

1 . A mask, comprising:
 a mask body;   an exhalation module that is formed at one surface of the mask body; and   an inhalation module that is formed at the one surface of the mask body and that comprises an inhalation filter,   wherein the inhalation filter comprises an anodized aluminum oxide film.   
     
     
         2 . The mask of  claim 1 , wherein a plurality of holes are formed in the aluminum oxide film, and the plurality of holes each have a diameter of 18 nm to 40 nm. 
     
     
         3 . The mask of  claim 1 , wherein the aluminum oxide film is formed in a honeycomb structure. 
     
     
         4 . The mask of  claim 1 , wherein the inhalation filter further comprises
 a dust-proof fiber that is disposed at both surfaces of the aluminum oxide film; and   a net-shaped partition that is disposed between the aluminum oxide film and the fiber.   
     
     
         5 . The mask of  claim 1 , wherein the inhalation module comprises an inhalation housing that houses the inhalation filter. 
     
     
         6 . The mask of  claim 1 , wherein the exhalation module comprises
 an opening and closing film;   a net-shaped partition that is disposed at one surface of the opening and closing film; and   an exhalation housing that houses the opening and closing film and the partition.   
     
     
         7 . The mask of  claim 1 , further comprising an adhesive module that is formed along an edge of the mask body at the other one surface of the mask body in which the inhalation module and the exhalation module are not formed. 
     
     
         8 . The mask of  claim 7 , wherein the adhesive module is a double-sided adhesive tape. 
     
     
         9 . The mask of  claim 1 , wherein the exhalation module is formed in a central portion of the mask body, and the inhalation module is formed in a pair in symmetry about the exhalation module. 
     
     
         10 . A method of manufacturing a mask, the method comprising:
 preparing a mask body;   forming an inhalation module inserting port and an exhalation module inserting port in the mask body; and   mounting an inhalation module and an exhalation module comprising an inhalation filter in the inhalation module inserting port and the exhalation module inserting port, respectively,   wherein the inhalation filter is formed by forming an aluminum oxide film by forming a hole by anodizing aluminum and by disposing a net-shaped partition and fiber at both surfaces of the aluminum oxide film.   
     
     
         11 . The method of  claim 10 , further comprising forming the aluminum oxide film and performing an etching process in order to adjust a size of a hole that is formed in the aluminum oxide film. 
     
     
         12 . The method of  claim 10 , further comprising anodizing the aluminum and removing an unoxidized aluminum layer. 
     
     
         13 . The method of  claim 10 , further comprising forming a double-sided adhesive tape along an edge of the other one surface of the mask body in which the inhalation module and the exhalation module are not formed. 
     
     
         14 . The method of  claim 10 , wherein the exhalation module is formed in a central portion of the mask body, and the inhalation module is formed in a pair in symmetry about the exhalation module.
