Embodiment 1

[0027] (1) Fix the functional groups that capture bacteria and viruses on the non-woven fabric: after cleaning the ultra-fine fiber non-woven fabric, put the 3- (Trimethoxysilyl) propyl dimethyl octadecyl quaternary ammonium chloride and an aqueous solution of an appropriate amount of initiator (such as dibenzoyl peroxide) are evenly sprayed on the nonwoven fabric to make it wet, and after ten minutes Then cross-link at 120-130° C. for 5 minutes.

[0028] (2) Dip-dyeing the sterilizing and disinfecting components onto the nonwoven fabric: triclosan is made into a sol of 5% (weight volume percentage), sprayed on the nonwoven fabric processed through step (1), and rolled and dried High-efficiency sterilization and disinfection materials are obtained.

[0029] The schematic diagram of the whole process is as figure 2 shown.

Embodiment 2

[0031] (1) Fix the functional groups that capture bacteria and viruses on the non-woven fabric: soak the ultra-fine fiber polypropylene non-woven fabric in acetone for 24 hours, wash it with distilled water until it is odorless, dry it at a constant temperature of 105°C, and then put it into a agent (such as dibenzoyl peroxide) and a concentration of 10% of the propylene functional group-containing sulfur compound allyl mercaptan in the polymerization bottle, exhaust oxygen with nitrogen for 5 minutes; then cross-link at 100 ° C After 30 minutes, take out the nonwoven fabric, wash it with acetone and 90°C hot water for 3-4 times to remove residual initiator and monomer, and then boil it with deionized water for 1 hour.

[0032] (2) Dip-dyeing the sterilizing and disinfecting components on the non-woven fabric: make a 10% solution of p-chloroxylenol, spray it on the non-woven fabric treated in step (1), and obtain high-efficiency sterilization by rolling and drying Disinfect ma...

Embodiment 3

[0034] (1) Fix the functional groups that capture bacteria and viruses on the non-woven fabric: soak the polyvinyl alcohol non-woven fabric in 7% ammonium hydrogen phosphate solution for 2 minutes, and dry at a constant temperature of 105°C; then the treated non-woven fabric The cloth was immersed in concentrated sulfuric acid and heated at 80°C for 90 minutes under the protection of nitrogen; finally, the nonwoven was washed with distilled water until neutral.

[0035] (2) Dip-dyeing the sterilizing and disinfecting components on the nonwoven fabric: preparing 10% silver nitrate solution, spraying it on the nonwoven fabric treated in step (1), rolling and drying to obtain the highly efficient sterilizing and disinfecting material.

Abstract

The invention discloses a sterilization and pasteurization material, comprising a substrate, wherein functional groups and sterilization and pasteurization components which can capture bacteria and / or virus are fixed on the surface of the substrate. The substrate is preferably made of non-weaving cloth with water-absorbing property. The invention also discloses a medical protective mask made of the sterilization and pasteurization material. Quaternary ammonium salt, sulfur-contained compounds and sulfoacid-contained compounds which are fixed on the surface of the sterilization and pasteurization material can be specifically combined with cell membranes of bacteria and viruses, actively captures the bacteria and the virus and can cause the sterilized and pasteurized components attached to the surface of the material to rapidly take effect. The sterilization and pasteurization material can rapidly kill the bacteria and viruses in five minutes. The medical protective mask has the functions of sterilization, antivirus, disease prevention, air purification and the like and can prevent the droplet transmission of the viruses.

Description

technical field [0001] The invention relates to a sterilizing and disinfecting material and its application. Background technique [0002] Traditionally used masks are all made of gauze, which must meet national standards for medical and sanitary protection. At present, the two main standards for protective masks in the world are the American standard and the European standard. The National Institute of Occupational Safety and Health (NIOSH) divides the standards of masks into three categories, namely N series, R series and P series. N is non-oily particles, R and P are oily particles, but R-level protective oily particles The efficiency is only eight hours and the P level has no such limitation. Each of these three categories has three standards of filtration efficiency: 95 (95%), 99 (99%), and 100 (99.97%), so there are nine kinds of masks in total. Since biological particles are mostly non-oily particles, N grade can be used. The N95 grade means that it can protect aga...
