Protective device, sterilization and disinfection composite sheet and manufacturing method thereof

Abstract

The invention provides a protective device, a sterilization and disinfection composite sheet and a manufacturing method thereof. The sterilization and disinfection composite sheet is at least providedwith a first sheet layer which comprises a melt-blown nonwoven fabric and a sterilization and disinfection catalyst, the sterilization and disinfection catalyst in a powdery form is compounded on themelt-blown nonwoven fabric and used for generating various active particles including gas-phase free radicals OH, ClO2, HO2 and O to realize adsorption, oxidation and/or purification of wounds, oral-nasal skin or infectious skin through the various active particles. By functional combination of the sterilization and disinfection catalyst and a band aid or a mask, air purification can be realized, and sterilization and disinfection of microorganisms in human bodies or air are realized; due to the characteristic of extreme limited space distance of effective efficacies of the gas-phase freeradicals, lifetime in existence of the gas-phase free radicals is about 10 nanoseconds, so that entering the human bodies is avoided, safety and cleanness are provided for users, and health and safety are guaranteed.

Description

technical field [0001] The present application relates to the technical field of sterilization and disinfection, in particular to a protective device, a sterilization and disinfection composite sheet, and a method for manufacturing the sterilization and disinfection composite sheet. Background technique [0002] In the air filtration, purification, sterilization and disinfection industries, a large number of polyester materials with high air permeability and low resistance are required to be used in composite materials for filter bags, filter elements and purifiers. At present, most of the substrates made of polyester long fiber technology appear on the market. The base material of this long-fiber process is limited by the long-fiber process, uneven cloth surface, low air permeability, high cost and other factors, resulting in a series of problems such as unsatisfactory performance of air filter products. [0003] On the other hand, the sterilizing and disinfecting material...

AI Technical Summary

Problems solved by technology

The base material of this kind of long fiber technology is limited by the influence of long fiber technology, the influence of factors such as uneven cloth surface, low air permeability, high cost, etc., resulting in a series of problems such as unsatisfactory performance of air filter products.

[0003] On the other hand, the sterilization and disinfection materials used in general Band-Aids are low in effect, and it is even more difficult to sterilize viral skin, so the application range is narrow and cannot meet the needs of users.
