▎ 摘　　要

NOVELTY - The preparation method of an antibacterial activated carbon mask involves: sequentially stacking a photocatalyst melt-blown non-woven fabric outer layer, an activated carbon melt-blown non-woven fabric inner layer and a pure cotton spun-lace non-woven fabric surface layer from top to bottom; placing the nose bridge strip in the middle of the upper end of the outer layer of the photocatalyst melt-blown non-woven fabric, and covering the nose bridge strip by the non-woven fabric; placing two ear belts at the left and right ends of the outer layer of the photocatalyst melt-blown non-woven fabric respectively; and carrying out hot pressing. A composite nano antibacterial agent prepared from graphene oxide, ferric chloride and bacterial cellulose is added in the outer layer of the photocatalyst melt-blown non-woven fabric. USE - Preparation method of an antibacterial activated carbon mask. ADVANTAGE - The antibacterial activated carbon mask is prepared by combining the outer layer with photocatalytic degradation, the copper-doped activated carbon filtering inner layer and the skin-friendly spun-lace non-woven fabric surface layer. The preparation process is simple, the functional layers are good in matching performance, the filtering efficiency on particles is high, and the mask has stable long-term service performance. The biomass waste is comprehensively utilized, the waste bamboo is used as a precursor of the activated carbon, the copper nitrate trihydrate is used as a mild modifier and a functional agent, and a structure regulator is added, so that the performance of the copper-doped activated carbon is obviously improved, and the filtering efficiency of the antibacterial activated carbon mask is further improved. The composite nano antibacterial agent prepared from graphene oxide, ferric chloride and bacterial cellulose is added on the outer layer of the photocatalyst melt-blown non-woven fabric, so that the antibacterial performance of the non-woven fabric layer is effectively improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the antibacterial active carbon mask. DESCRIPTION OF DRAWING(S) - The drawing shows a field emission scanning electron microscope image of the activated carbon.
