Abstract

The invention provides a silk-based mask material with high adsorption and formaldehyde decomposing ability and a preparation method thereof. The silk-based mask material comprises silk fibers, cellulose aerogel particles and birnessite particles. The preparation method includes: chopping fresh banana peel, boiling in water, adding sodium hydroxide, continuing constant-temperature water bath processing, filtering to obtain filter residues, and subjecting the filter residues to etherification to obtain banana-peel-based carboxymethyl cellulose; adding the banana-peel-based carboxymethyl cellulose into a fibroin solution, evenly mixing, grinding in a water bath environment, slowly adding an acid solution containing trichloromethane, solidifying into spheres, taking out, sufficiently cleaning, and performing freeze drying to obtain fibroin / cellulose aerogel particles; degumming silk, cutting off to form a silk chopped fiber solution, defibering and beating, adding the fibroin / cellulose aerogel particles and the birnessite particles, evenly mixing, and using the sheet making technology to prepare the silk-based mask material with high adsorption and formaldehyde decomposing ability.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a silk-based mask material with strong ability to absorb and decompose formaldehyde and a preparation method thereof. Background technique [0002] Formaldehyde is a colorless, pungent and irritating gas at room temperature. It mainly comes from indoor furniture coatings, floor materials, wallpaper and smoke from cigarette burning. Its concentration is greater than 10 for a long time -7 A series of indoor air syndromes will be caused in the formaldehyde environment, which will affect people's health and the safety of the living environment. At present, the methods for treating indoor formaldehyde pollutants include adsorption, catalytic oxidation, and plant filtration. Among them, the adsorption method is the main method for removing formaldehyde, and activated carbon particles are mainly used to adsorb formaldehyde. However, activated carbon particles do no...
