Embodiment 1

[0023]A 0.3 mm thick nickel foam was used as the carrier. The nickel foam was treated as follows: firstly, it was degreased by ultrasonication with acetone for 30 minutes. Then foam nickel was dropped into 6.5mol / L HCl and soaked for 15 minutes, then cleaned with deionized water, and then dried in a 60-degree drying oven for 3 hours.

[0024] The treated foam nickel in 2.5mmol / L of H 2 PtCl 6 ·6H 2 Soak in O solution for 45 minutes. Afterwards, the nickel foam was dried at 85° C. for 8 hours, and then baked in an oven at 300° C. for 3 hours under the condition of feeding hydrogen. Then repeat the above soaking, drying and roasting steps.

[0025] Next, 10 g of activated carbon, 15 g of polyquaternium-10, and 75 g of PVA were added to 120 mL of acetone and dissolved, after which a solution of 2.0 g of ammonium oxalate in 40 mL of water was added and mixed uniformly. The above-mentioned mixture was coated on one side of the above-mentioned nickel foam to obtain an antibact...

Embodiment 2

[0030] A 0.4 mm thick iron-nickel foam was used as the carrier. The iron-nickel foam was treated as follows: firstly, it was degreased by ultrasonication with acetone for 30 minutes. Then put the iron-nickel foam into 6.5mol / L HCl and soak for 15 minutes, then wash it with deionized water, and then dry it in a 60-degree drying oven for 3 hours.

[0031] The treated foamed iron-nickel in 3.5mmol / L RuCl 3 ·3H 2 Soak in O solution for 45 minutes. Afterwards, the iron-nickel foam was dried at 85° C. for 8 hours, and then baked in an oven at 320° C. for 3 hours under the condition of feeding hydrogen. Then repeat the above soaking, drying and roasting steps.

[0032] Next, 20 g of activated carbon, 45 g of polyquaternium-7, and 35 g of ethylene-vinyl acetate copolymer EVA were added in 140 mL of acetone, followed by a solution of 2.5 g of ammonium oxalate in 50 mL of water and mixed well. Coating the mixture on one side of the foamed iron-nickel to obtain an antibacterial adso...

Embodiment 3

[0037] 0.3mm thick copper foam was used as the carrier. The copper foam was treated as follows: first, it was degreased by ultrasonication with acetone for 30 minutes. Then put the copper foam into 6.0mol / L HCl and soak for 15 minutes, then wash it with deionized water, and then dry it in a 60-degree drying oven for 3 hours.

[0038] The treated foam copper in 3.0mmol / L of PdCl 2 2H 2 Soak in O solution for 45 minutes. Afterwards, the copper foam was dried at 90° C. for 8 hours, and then fired in an oven at 350° C. for 3 hours under the condition of feeding hydrogen. Then repeat the above soaking, drying and roasting steps.

[0039] Next, 20 g of activated carbon, 35 g of polyquaternium-7, and 45 g of PET were in 140 mL of acetone, followed by a solution of 2.5 g of ammonium bicarbonate in 50 mL of water and mixed well. The above-mentioned mixture was coated on one side of the above-mentioned foamed copper to obtain an antibacterial adsorption coating. It was then dried ...

Abstract

The invention provides a general-type mask which comprises a mask body and ear hangers or headbands symmetrically connected to the two sides of the mask body. The mask body is provided with a rigid contour completely consistent with human facial characteristics. The mask body is formed by a first non-woven fabric layer, a honeycomb catalytic metal layer, a porous anti-bacterial adsorption composite layer, a nanoporous filter polymer layer and a second non-woven fabric layer from outside to inside. The nanoporous filter polymer layer is provided with micro-structures with nanopores densely distributed in a range of average pore diameter at 30-45 nm. The general-type mask has the advantages of excellent PM2.5 filtration efficiency, bacterial filtration performance and oil fume removal rate, and is comfortable and beautiful to wear.

Description

technical field [0001] The invention belongs to the field of sanitary products, and in particular relates to a general-purpose mask. Background technique [0002] At present, environmental problems, especially air pollution, have become serious social problems, affecting people's normal life and health more and more. For example, with the development of industry, the number of factories increases, people burn fossil fuels, such as oil, coal, etc., and the pollutants discharged into the air are increasing day by day, resulting in more and more smog weather. According to reports, smog is an important cause of cardiovascular diseases and respiratory diseases, and the concentration of inhalable particulate matter in the air increases by 10 μg / m 3 , respiratory diseases rose by 3.4%, cardiovascular disease rose by 1.4%, and the total daily death rate rose by 1%. In addition, traditional Chinese cooking methods will produce a large amount of oily fumes, which contain toxic chemi...
