Embodiment 1

[0070] This embodiment prepares a protective material, and the specific preparation method is as follows:

[0071] 1) Preparation of positively charged filter layer:

[0072] Mix didecyl dimethyl ammonium chloride and n-alkyl dimethyl benzyl ammonium chloride with a mass ratio of 60:40 to obtain a compound quaternary ammonium salt. After mixing hypromellose (molecular weight 50,000) with water, add the Compound quaternary ammonium salts to obtain a suspension. The mass ratio of the compound quaternary ammonium salt and hypromellose is 20:1, and the overall concentration of the compound quaternary ammonium salt and hypromellose in water is 5%.

[0073] After soaking the non-woven fabric in the above-mentioned suspension for 25min, dry it for later use, and the composite ratio (loading capacity) of the composite quaternary ammonium salt and the non-woven fabric is 30g / m 2 (That is, the final load of 30g of composite quaternary ammonium salt per square meter of non-woven fabric...

Embodiment 2

[0082] This embodiment prepares a protective material, the specific preparation method is the same as that of Example 1, the only difference is that the composite ratio of composite quaternary ammonium salt and non-woven fabric is 60g / m 2 ; The composite ratio of graphene oxide / titanium dioxide composite nanoparticles and non-woven fabric layer is 30g / m 2 ; The composite ratio of the composite of calcium oxide and magnesium oxide to the non-woven layer is 30g / m 2 .

Embodiment 3

[0084] This example prepares a kind of protective material, the specific preparation method is the same as Example 1, the only difference is: the compound ratio of compound quaternary ammonium salt and non-woven fabric is 10g / m 2 ; The composite ratio of graphene oxide / titanium dioxide composite nanoparticles and non-woven fabric layer is 10g / m 2 ; The composite ratio of the composite of calcium oxide and magnesium oxide to the non-woven layer is 60g / m 2 .

Abstract

The invention relates to the technical field of materials, and specifically discloses a protection material as well as a preparation method and an application thereof. The preparation method comprisesa positively-charged filter layer and a nanometer anti-phytopathogenic layer, wherein the nanometer anti-phytopathogenic layer comprises a composite layer formed by a photocatalytic reaction generation layer and an active hydroxyl radical generation layer; and the photocatalytic reaction generation layer is a filter layer supported with graphene oxide / metallic oxide composite nanometer particleswith photocatalytic performance, and the active hydroxyl radical generation layer is a filter layer supported with basic metal oxide. The material has the characteristics of being long in protection time, good in antiviral effect, and comfortable to use, and is appliable to preparation for various medical protection products, and capable of providing effective virus protection for high-risk population.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a protective material and its preparation method and application. Background technique [0002] Influenza virus can cause infection and disease in many animals such as humans, poultry, pigs, horses, bats, etc. It is mainly transmitted through droplets in the air, contact between susceptible and infected persons, or contact with contaminated objects. The easiest, economical and effective way to block influenza and other respiratory diseases is to wear protective equipment. Ordinary protective equipment mainly includes masks, which are generally made of cotton, hemp and other gauze or synthetic fibers, and mainly trap air through electrostatic adsorption and mechanical filtration. Particles, droplets, dust and other substances in the mask have a certain protective effect on the virus, but they cannot achieve effective isolation, and the virus surviving on the discarded mask will ...
