Abstract

The invention discloses a polypropylene non-woven fabric modified with chitosan-metal complex and a preparation method thereof. The non-woven fabric comprises the following components in parts by weight: 35-55 parts of polypropylene non-woven fabric, 20-35 parts of chitosan, 11-19 parts of hydrochloric acid, 8-22 parts of sodium bicarbonate, 2-11 parts of sodium hydro-acetate, 7-18 parts of absolute ethyl alcohol, 12-23 parts of aluminum chloride, 12-23 parts of aluminum chloride, 13-25 parts of ferric chloride, 11-23 parts of zinc chloride, 13-21 parts of sodium p-styrenesulfonate, 4-11 parts of N-vinyl-2-pyrrolidone, 4-12 parts of acrylamide and 1-8 parts of acrylic acid. The polypropylene non-woven fabric modified with chitosan-metal complex disclosed by the invention is capable of effectively absorbing wastewater; the polypropylene non-woven fabric modified with chitosan-metal complex disclosed by the invention has a certain antibacterial function; and the polypropylene non-woven fabric modified with chitosan-metal complex disclosed by the invention is reusable.

Description

technical field [0001] The invention belongs to the field of material chemistry, and relates to a functional nonwoven fabric material, in particular to a chitosan-metal complex modified polypropylene nonwoven fabric and a preparation method thereof. Background technique [0002] Chitosan molecules contain a large number of intramolecular and intermolecular hydrogen bonds, so they are insoluble in water and alkaline solutions at normal temperature and pressure, soluble in inorganic acids such as dilute hydrochloric acid and nitric acid and most organic acids, and insoluble in dilute sulfuric acid and phosphoric acid. Chitosan molecules have a complex double-helix structure, and the molecular chain segments contain a large number of active amino groups, hydroxyl groups, and N-acetyl groups. At the same time, the active structure of its polymer chains also makes it highly efficient. On the one hand, they will form Various intramolecular and intermolecular hydrogen bonds, on the...
