Abstract

The invention discloses a composite non-woven fabric suitable for oil-water separation and a preparation method thereof. The non-woven fabric comprises: 28-50 parts of polypropylene non-woven fabric,12-26 parts of acetone, 10-25 parts of acrylic acid, 12-25 parts of benzophenone, 13-19 parts of dichloroethane, 8-19 parts of calcium chloride, 8-19 parts of sodium carbonate, 19-32 parts of calciumcarbonate, 15-28 parts of n-hexadecane, 17-27 parts of sodium periodate, 7-20 parts of ethylenediamine, and 23-39 parts of dimethylsulfoxide. According to the method, a co-radiation method is employedfor grafting of acrylic acid to the polypropylene non-woven fabric and then mineralization is carried out, in a solid-water-oil three-phase system, a mineral layer on the non-woven fabric surface plays a role of rigid and stable moisture retention layer, and a mineralized membrane shows the underwater superoleophobic and oil drop adhesion layer effects. The composite non-woven fabric suitable foroil-water separation provided by the invention has the advantages of high oil phase disruptive pressure, small transmembrane resistance, and high retention rate of large-size emulsion droplets.

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 composite nonwoven fabric suitable for oil-water separation and a preparation method thereof. Background technique [0002] With the rapid development of society and the steady advancement of industrialization, people use more and more oil products. While meeting the needs of human material production and life, it also brings great challenges to environmental protection worldwide. On the one hand, oil-intensive industries such as oil refining, textiles, and food industries produce a large amount of oily wastewater every year, which seriously threatens water quality safety; on the other hand, oil spills from drilling platforms or ocean-going cruise ships have occurred frequently in recent years. When a large amount of crude oil is leaked into the seawater, the clean oil components will form a thin film on the ocean surface, h...
