Problems solved by technology

Such masks often need to be irradiated by ultraviolet light to produce sterilization and disinfection effects. However, most medical workers work indoors, and indoor ordinary lighting does not contain ultraviolet light, which cannot make such masks produce sterilization and disinfection effects. Therefore, this type of mask is not suitable for medical places

Abstract

The invention discloses a method for preparing a disinfecting mask suitable for medical places. The steps are as follows: 1) adding the treated activated carbon into the ferrous oxalate dispersion, evaporating in a water bath, putting it into a muffle furnace for calcination, and obtaining Ferrous oxide / activated carbon composite powder; 2) Add ferrous oxide / activated carbon composite powder to the prepared passivation solution, stir and stand to prepare silane-coated ferrous oxide / activated carbon composite powder; 3 ) adding manganese nitrate and cobalt nitrate to citric acid solution, stirring, drying, pulverizing and then roasting to obtain manganese / cobalt composite oxide; Spray the gel-like liquid on the substrate to make a functional layer, and then sew the functional layer on the outer surface of the mask to make a disinfection mask. The disinfection mask has an efficient and durable antivirus and sterilization effect in medical places, can provide good protection for medical staff, and is suitable for large-scale promotion.

Description

technical field [0001] The invention belongs to the technical field of medical supplies, and in particular relates to a preparation method of a disinfection mask suitable for medical places. 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, and masks in hospitals can also play a role in isolating germs. [0003] The disinfection and sterilization effect of traditional medical masks is not thorough enough. In order to achieve a better effect of isolating germs, it is often necessary to make the masks very thick, which not only costs a lot, but also is inconvenient to wear. To the passive filtering effect, can not play the role of actively killing germs, there is a deficiency in the protection of the human body. At present, a new type of medic...
