Abstract

The invention discloses a nano-material antibacterial mask which comprises a filter material, and the filter material comprises bamboo charcoal fibers and graphene oxide; the bamboo charcoal fibers are hollow, and the pipe wall of each bamboo charcoal fiber is spiral. When the product is prepared, the preparation method comprises the following steps: preparing modified graphene oxide: sequentiallytaking 10-20 parts by weight of graphene oxide, 80-100 parts by weight of absolute ethyl alcohol, 10-20 parts by weight of fatty acid and 8-10 parts by weight of titanate; and mixing graphene oxide,absolute ethyl alcohol, fatty acid and titanate, carrying out ultrasonic dispersion uniformly, carrying out heating reflux reaction, and carrying out suction filtration, washing and drying to obtain modified graphene oxide. According to the technical scheme, the obtained product not only has small air suction resistance, but also has good filtering efficiency; and the contradiction between the filtering efficiency and the air suction resistance is effectively solved.

Description

technical field [0001] The invention relates to the technical field of anti-virus and PM2.5 masks, in particular to a nano-material antibacterial mask based on bamboo charcoal fiber and graphene oxide composite and a preparation method thereof. Background technique [0002] At present, China's air pollution situation is severe. Most of the primary pollutants are PM2.5 and PM10, and the PM2.5 value in Beijing exceeds 900. Air pollution can not only have a destructive effect on surrounding objects through physical, chemical, and biological erosion, but also pollute the respiratory system (lungs), skin epidermis and other parts of our respiratory system, nervous system, immunity, skin, Liver, endocrine system and other toxic effects. At the same time, it can affect people's mental state, prone to adverse reactions such as fatigue and tension, and reduce work and study efficiency. Living and working in an environment with poor air quality for a long time will not only cause a...
